Elevator group control system refers to the installation of a number of elevators in a building, and these elevators and a computer connected. The computer can collect the various signals of each elevator, through the scheduling algorithm to each elevator issued a control command. In short, the elevator group control technology can be based on changes in the volume of traffic in the building, the operation of each elevator deployment, the purpose is to achieve the best service ladder group and reasonable operation and management.

The traditional group control algorithm has only one goal, the minimum waiting time. In the case of some specific traffic modes of modern high-rise buildings, it is impossible to require each elevator to serve every floor. Therefore, the research of elevator group control system scheduling algorithm has important practical significance. Intelligent group control technology not only represents the direction of industry technology development, but also will bring more convenience to people.

Comments: We often take the elevator in the daily, often encounter such a scenario, that is, press the call button, to wait for a long time to reach the elevator, a lot of time wasted. The traditional elevator control algorithm causes the elevator to run inefficient, prone to elevator get together, causing the user to take a long time and take a long time, and the elevator to stop the number of too many, resulting in energy waste. Take the intelligent group control technology elevator can avoid the occurrence of the above situation.

Metal material: mainly to stainless steel-based, for the car wall, car doors, hall doors, and door frame decoration. According to the degree of luxury hair panels, mirror panels, mirror etching plate, titanium plate, gold plate and so on.

Wooden material: mainly used for car wall, ceiling rack and floor decoration. Car wall decoration with a lot of wood materials, such as red beech, white beech, bird eyes, black walnut and even mahogany. Suitable for star hotels and other decoration requirements of the higher places. Ceiling wood materials and cars used to be consistent. The floor is the wooden floor. Decoration of wooden use of wood materials require fire treatment, in line with fire acceptance standards.

Glass: including glass, mirror, for car wall decoration. If you use mirror stainless steel can not mirror.

Artificial materials: mainly used for the ceiling used by the light plate, light beam and other man-made materials. The ceiling is also divided into a variety of grades to match the different car decorations. Car handrails with artificial materials are also more. Of course there are metal and wood materials.

Area measurement problem: the user uses the elevator car’s internal dimensions, width, depth, height; door frame size, width and height. If the car is not a regular rectangle but also draw, the corner part of the measurement accuracy. Door decoration to measure the width and height of the door. With these dimensions, the factory can process the corresponding product.

As for the offer: generally in accordance with user requirements, sub-offer, such as how much the car, the door how much money. Each production and decoration of the company has its own price positioning. If you do the agent, then add their own profits on it.
Another point, need to pay attention to: elevator decoration will change the balance of the elevator. If the user is a new elevator, the weight of the decoration should be estimated in advance to tell the elevator factory. If you are in the elevator decoration, need to be adjusted by the elevator commissioner.

Elevator automatic control system has become a computer technology applications in the field has a very dynamic branch. In order to meet the high requirements for the flexibility, reliability and functionality of the system, the developed system is based on microcomputers. This system is a 4C technology, namely, computer technology (COMPUTER), automatic control technology (CONTROL), communication technology (COMMUNICATION) and conversion technology (CHANGE) into a highly related, integrated system. It has obvious superiority in the control range, adaptability, maintainability, system stability and so on, and has become the cornerstone of the development of elevator control technology. System stability and many other aspects of the previous control system has obvious advantages, and has become the cornerstone of the development of elevator control technology.

Elevator speed tends to ultra-high speed

With the mass of skyscrapers, the elevator running speed constantly challenge, but also to promote the development of elevator technology. At present the world’s highest speed of the elevator has reached 17m / s, more 18m / s elevator will run in more than 600 meters high “Shanghai Center Building”. Can be expected, with multi-purpose, full-featured high-rise building development, ultra-high-speed elevator will continue to be the direction of research and development. Large capacity traction motors, high-performance microprocessors, vibration reduction, noise suppression technology, car automatic pressure control system, suitable for ultra-high-speed elevator safety components and other technologies will be actively promoted.

The popularity of green elevators is an inevitable trend

Energy-saving, environmentally friendly materials in the elevator parts on the application has been exposed. Permanent magnet synchronous gearless traction machine, energy feedback device is rapidly improving the machine matching rate. Non-metallic materials made of car wall, guide wheel, traction wheel has been put into use. The elevator suspension system replaces the traditional traction wire rope with a flat composite traction strip. The use of non-metallic materials made of rope to replace the rope is more revolutionary. In addition, the use of linear motor-driven elevator also has a larger research space. The two elevators that share the same hoistway are already running. Elevator group control system more intelligent. Such as expert system, fuzzy logic group control system can adapt to the elevator traffic uncertainty, control the diversity of objectives, non-linear performance and other dynamic characteristics. With the development of intelligent buildings, the intelligent group control system of the elevator can be combined with all the automation service equipment of the building into the whole intelligent system.

Today for everyone popular science in the elevator when the elevator lift the five major considerations:

1, press the switch door button repeatedly

Many people after entering the elevator, because the time and repeatedly press the door switch button, hoping to improve the door speed. In fact, this behavior will not only speed up the door speed, but affect the elevator running the program sensitivity.

2, the elevator overtime to open the door and others

Warm tips you: elevator door, waiting time are already designed a good program. Manual interference with the design of a good program, will cause the elevator computer program disorder, reduce the elevator sensitivity.

3, transport decoration garbage, throw debris

Handling debris into the elevator, may make some debris into the elevator inside the running parts, resulting in elevator stuck and stop running. So fast off the king to suggest that if you need to carry debris, try to pack a good, reduce the chance of falling off the waste.

4, handling furniture, building materials and other heavy objects hit the elevator

When the elevator received a collision may be dislocation, causing the elevator emergency brake closed or fall accident, therefore, fast off the king that the handling of heavy objects hit the elevator is all the wrong operation of the elevator damage the most serious consequences.

5, forced to squeeze when overloading

In the busy working life, there may be some passengers in the know that the elevator has been overloaded under the premise or do not want to give up, forced to squeeze into. Here to remind you: the elevator has a rated capacity, overloading the elevator will take the alarm and other self-protection measures, such a long operation may lead to elevator procedures disorder.

Everyone in the hurry on the occasion of the trip, be sure to abide by the safe operation of the elevator code of conduct, the safety of the first can greatly avoid the elevator safety accident, do not step on the elevator safety “minefield” Oh!

After the Eighth Fifth Plenary Session also put forward: try the network strategy and the implementation of the “Internet” action plan, the development of sharing the economy, the implementation of national large data strategy.

“Cloud” to solve the problem is to eliminate the information island and data fusion, “calculation” to solve the problem is to dig the value behind the data.

Elevator companies to install the service platform are based on large data for the calculation and analysis of relying on.

5, visual technology – intellectual creation of the necessary weapons

“Smart” era struck, intelligent manufacturing will become the future direction of development. In the intelligent manufacturing process, the machine vision mainly uses the computer to simulate the human visual function, has the human part of the brain function, that is, the object of the image of the information extracted, processed and understood, and ultimately for the actual detection, measurement and control The In the next few years, with the development of China’s manufacturing industry, people’s demand for machine vision will gradually increase.

Industry analysis, with the development of machine vision, the future application of new industries may occur. Industrial production is relatively large in the logistics industry, in particular, will involve 3D vision. Civil service may need more experience, the difficulty lies in the environmental variability, the redundancy of the algorithm requires a higher, civil applications will mainly come from the consumer level of the product.

At present, the threshold of machine vision components is mainly embodied in the software algorithm, and the current domestic enterprises in dealing with speed and ability, there are large gaps, and because the industry started late, shipments, hardware prices are no advantage. This is 2016 years and the future to break the place.

6, virtual reality – science and technology of the bright star

Virtual reality technology is also called VR technology, is the new darling of the technology sector, some people think that in 2016 it will board the top of the geek search list. According to research institutions forecast, by 2020, the global VR market size will reach 150 billion US dollars, in the smart hardware entry snatch, the virtual reality technology will be more eye-catching, and ushered in the vigorous development of the entire market.

Virtual reality technology refers to the use of computers and advanced sensor technology to create a new form of human-computer interaction, including simulation environment, multi-perception conduction, natural skills and other aspects, and more for the game, tourism, sports, environmental protection and other fields. For example, in the field of games, users can experience the horror of the horror game through the VR technology, home to see the haunted house around the world, but also with their own fans of the same stage of competition; through the virtual reality, you can also view the idol at home concert.

In 2016, the combination of virtual reality technology and specific scene applications, B-side application class, channel class, hardware device class standard will be developed. In the long run, to create a complete ecological closed-loop, layout content, platform and the whole industry chain to determine the future virtual reality market can eventually detonate.

7, wireless communication – the world because of its connection

According to forecasts, by 2020 or so, the world will have more than 50 billion devices to achieve networking. Wireless connectivity as a key component of embedded applications plays an important role in the deployment of millions of things, making it a key part of the design of the Internet of Things. At present, we have seen a combination of wearable devices that can be used in combination with wireless transmission technology, home automation, home security, personal care, smart home appliances, accessories and remote controls, automotive, lighting, industrial internet and more.

Taking 5G as an example, there is a growing demand for ultra-high flow density, ultra-high connection density and ultra-high mobility, which requires that the mobile communication network must accelerate to a higher level in the international communications industry. Into the substantive stage of development.

China’s 5G in the footsteps did not fall, China Telecom recently signed a cooperation plan with the Guangdong Provincial Government, will take the lead in Guangdong to carry out 5G mobile communication network trial and deployment, and China Mobile led the 5G system architecture design has also been 48 global companies stand by. Visible, mobile Internet technology will become the “world connection” key.

8, intelligent sensing – one end of the data source

Sensors as the information age to achieve intelligent manufacturing of important equipment in the field of science and technology, industrial and agricultural production and daily life plays an important role. We have to implement the “Made in China 2025”, to achieve intelligent manufacturing, we must pay close attention to the sensor market.

Under the trend of technological development, the United States, Japan, Britain, France, Germany and other countries put the sensor technology as one of the key technologies of national key development. In recent years, China’s sensor industry has shown a rapid growth, such as photosensitive sensors, its production capacity in 2014 reached 450 million, the market demand industry reached 250 million, the data show that the market prospects for light sensor development.

Sensors in the Internet of Things market growth under the pull, was steady development, 2015 China’s sensor market size or will reach 120 billion yuan.

9, fast charging technology – intelligent equipment “mobile” key

This year there is an ad, we are familiar with, “charging 5 minutes, call two hours.” This sentence is about the role of fast charging technology. In 2015, fast-charging technology to support mobile devices more and more, if a cell phone does not support fast charging technology has been embarrassed to say that they belong to this dream era.

Fast charging demand is to increase mobile devices, new energy equipment to promote and improve. To new energy vehicles, for example, charging a large-scale promotion of new energy vehicles a major obstacle to the construction of the charging pile infrastructure throughout the country can not meet the new energy vehicle charging needs. This time, fast charge to become a new energy vehicle life-saving straw. Now some car manufacturers began to research and development in 5 minutes to complete the electric car charging technology, which is bound to the electric car ecosystem to bring about revolutionary changes.

In the power outage state, continuous cruise battery technology has been successfully developed and applied, fast charging technology to overcome, the elevator in the state of power to continue to work as possible.

10, unmanned aerial vehicles – industrial applications, civilian consumption at the same time the outbreak

In 2015, the global unmanned aerial vehicle market is rapidly expanding, and the US Federal Aviation Administration (FAA) has estimated that more than 1 million UAVs will be sold in the 2015 Christmas season. At the same time, as countries continue to loosen unmanned aerial vehicle application laws and regulations, the future UAV will continue to create huge economic benefits, including UAV manufacturers, UAV operators and chip operators are full of fire, UAV market opportunities.

In the industrial field, the current unmanned aerial vehicles in the power, security, agriculture, forest fire, police and other applications in different areas of steady growth, the overall accumulation in the accumulation stage. At the same time, the consumption of unmanned aerial vehicle market to enhance the UAV in different applications in the field of visibility, to a certain extent, promote the UAV in the industrial market promotion.

China’s industrial UAV manufacturing applications are still in the initial stage and demonstration stage, has not yet formed a large-scale market, but in the national industrial development strategy to guide and promote the promotion of policies, China’s industrial-grade unmanned manufacturing and market Applications will be in the next few years to achieve greater development.

Elevator business aerial video video is the most early UAV shooting useless. Perhaps the future space shuttle will change the way people travel.

In technology so developed today, everything is possible to achieve, but some need more time to achieve “perfect”. The top ten emerging technologies, are “Xiao He was exposed sharp corners,” the emerging technology, they in 2016 or even longer in the future will be a “bloom.”

First, the elevator type to determine

During the planning period of the building, the use of the building should be clarified because the type of elevator used varies considerably depending on the buildings of hotels, office buildings, hospitals, residential or industrial and mining enterprises, and, once determined, It is very troublesome to change. After determining the use of the building, according to its construction area, floor (height), access to personnel flow, the elevator where the location of the building and other factors to make passenger flow analysis in order to determine the elevator speed (minimum speed to meet the requirements of fire forced landing), load (Large engine room, small room, no room), traction machine type (traditional turbine vortex and new permanent magnet synchronous).

Second, planning approval after the start of procurement

Procurement time It is recommended to start purchasing after planning approval. In the elevator type, speed, load, the number of stations, stop the number of stations, the total length of the trip, etc., can be commissioned by the architectural design department design blueprint, and the elevator building (mainly elevator shaft) part of the design department is usually professional Elevator manufacturers to provide the same type of standard civil construction drawings, combined with the building elevator shafts different structures such as brick structure, concrete structure, brick structure or steel structure drawing drawings. This size to consider the general, to meet the needs of manufacturers in general. However, different elevator manufacturers of the shaft design size, room and pit requirements are still different, if the advance to determine the manufacturers, according to the selected manufacturers of drawings designed to reduce the use of space waste, but also reduce the trouble of future construction. If the shaft is large, waste area; if the shaft is small, some manufacturers simply can not meet, it is necessary to non-standard production, increase a lot of cost.

Third, a reasonable choice of manufacturers and brands

Elevator manufacturers and brands in the world eight brands also have grades of points, there are the first legion and the Second Army said. Domestic elevator business is also a lot. The elevator is also a penny. You can according to their own budget and project positioning to select the same level of the unit tender. But also a large area of ​​choice, and ultimately according to the degree of difference and then determine which grade. Elevators also have dealers and agents, they will be high prices, but the strength can be advanced. Usually choose manufacturers, so that quality is guaranteed, the service can find the root, but the payment conditions are more harsh. Industry practice is required to have a prepayment, delivery before the full amount or basic full amount. Elevator factory should be necessary business license, elevator production license, its construction sector construction enterprises grade qualification, installation safety certificate and other supporting documents.

Fourth, the interface to facilitate the transfer

Interface installation Elevator installation and the total package construction units (civil and installation), fire units, weak units are closely related to each other’s interface to be clear, the construction process to do the transfer.

Fifth, due to the need to select the elevator function

Each elevator factory has an elevator function table, the purchasing staff to understand its function. Some functions are mandatory, they can not fall. Some features are essential to the elevator, no election will have. Some features are auxiliary, not a must, you can choose. According to the project positioning selection function. The more features, the higher the price, in fact, not necessarily practical. Especially the barrier-free elevator function, residential projects, there is no mandatory requirements in the completion of the acceptance, the usual practice is not to be considered, for the stretcher elevator, the design specification has a mandatory requirement. For public projects, accessibility is considered complete. Elevator button arrangement, to consider the convenience, beautiful, but also consider the people and foreigners are sensitive to some figures, 13,14 and other letters instead. Tender requirements of the elevator manufacturers to offer a variety of options for reference when the standard selection.

Six, clear price to avoid disputes

The total price of the elevator project should include all the equipment prices, transportation costs, customs (into the ladder), insurance, installation fees, commissioning fees and manufacturers commitment to the owner of pre-sale, after-sales warranty and other related costs, but here need to explain, The construction department to the owners of the delivery has been installed acceptance, and qualified elevator, some late costs should be borne by the owners, such as elevator registration fee, installation inspection fee, fire (equipment) inspection fees, elevator annual inspection fees. The above costs, both supply and demand should be implemented as far as possible in the contract, in the form of clear the responsibility of both sides is the best way to avoid disputes. Tender requirements of the elevator manufacturers reported that the price of damaged parts and maintenance costs, this department costs related to the future use of the cost of operation, the property company is more concerned about.

Seven, the overall planning delivery time

Owners for their own building construction progress, may require the production of elevator manufacturers a clear date of supply, and now the general manufacturers need to supply two and a half months to four months, and the general building elevator equipment approach is best in the building has been capped, It is necessary to dismantle the outdoor tower crane before the appropriate, if the arrival of this before, is bound to occur storage and storage problems, and after this will appear twice the lifting, handling and other costs. Usually the elevator factory will have a certain period of free storage period, more than this time not delivery, the factory will receive a fee.

Eight, a good elevator to install three links

A good elevator, to control the following three main links (also known as three stages).

First of all elevator equipment product quality, which requires the elevator manufacturer of its production quality of the protection of the elevator is a special equipment, with production certificate of production quality is usually not a big problem, but the durability, stability will be difference.

Second, pay attention to the level of installation and commissioning process, the installation quality is very important, each elevator factory installation team are their own or long-term cooperation, but also assessment, commissioning are generally arranged by the elevator factory responsible person.

Third, after-sales service, and now the elevator is sold after the professional maintenance team is responsible for the elevator factory and the property company signed a maintenance contract, which ensures the continuity of the elevator factory work. Maintenance and management of the rational and timely, to ensure the quality of the use of the elevator. So the country as early as the early 90s by the Ministry of Construction issued a red tape, clearly stipulates that the elevator products by the manufacturer “through-train” service, that is, the elevator manufacturers to produce their own elevator equipment warranty, installation commissioning, maintenance And so on.

Nine, elevator acceptance can not be sloppy

Elevator is a special equipment, the State Bureau of Technical Supervision has acceptance procedures, but they are usually responsible for security, acceptance is also fly. So the owners and supervision units, to strictly out of the box acceptance, process monitoring, hidden acceptance, functional acceptance and so on. Must be in accordance with the elevator acceptance criteria and the functions identified in the contract one by one acceptance, an elevator an elevator acceptance.

10, hand control elevator safety

Elevator installation and commissioning is completed, the internal acceptance is completed, with the use of conditions. According to regulations, the elevator is not allowed to use the technical supervision bureau is not allowed to use, but usually this time the elevator has been removed, the total package unit other work is not completed, need to use the indoor elevator. Elevator units and the total package unit signed an agreement, the elevator unit arrangements for people to open the elevator, the total package unit according to the requirements of the elevator unit to use the elevator and bear the cost. After the completion of the project, do a comprehensive inspection and maintenance. After the completion of the project as a whole, the elevator company transferred to the maintenance unit, the total package transferred to the property company management.
