With the development of China's modernization construction, elevators are widely used in commercial office buildings, high-rise residential quarters and other places where people enter and exit daily, and become an indispensable tool for people to enter and exit these high-rise buildings. The IC card elevator control system has gradually become one of the weak current systems in intelligent buildings. The following describes some of the functions and technical implementation methods of intelligent elevator access control.
1. Swipe to the designated floor. At the time of card issuance, the authority of the card user to reach the floor is authorized.In use, when the user enters the elevator and swipes the card on the card reader, the access control panel determines whether the card is valid and can reach the floor. When the output conversion board converts the signal into the start of the relay, the corresponding floor is automatically pressed. Button, the elevator can drive to the designated floor. At this time, the cardless user button is invalid, and the illegal elevator is restricted.
2. Open the button permission after swiping the card, and manually press the button to reach the floor you want to go. When the card is not swiped, in addition to the common layer button (such as the floor, -1 floor, etc.), the other floor buttons are locked. After the card is swiped, the elevator accesses the button of the authorized floor, that is, the relay conduction button corresponding to the authorized floor button is valid, and the elevator starts to operate when the user presses the button corresponding to the authorized floor. Unauthorized floor buttons are invalid.
3. Intercommunication function. At the time of card issuance, in addition to the floor where the authorized user is located, the floor that can be authorized to visit each other can be authorized. For example, the user on the 16th floor can apply for opening the 12th, 13th, and 15th floors in addition to the 16th floor. When swiping the card directly in the elevator, the elevator directly takes the user to the 16th floor. If the user wants to visit the friend on the 13th floor, the elevator button in the elevator is pressed, and the elevator is switched to the open permission state. Then, swipe the card, the elevator opens the buttons on the 12th, 13th, and 16th floors, the user presses the 13th floor, and the elevator can take the user to the 13th floor.
4. Temporary visitor function. Temporary cards can be issued for temporary visitors. At the time of issuance, the effective time period of the temporary card, the effective floor, the effective elevator, and the number of valid credits can be authorized, and the use within the authorized range is valid. This information is loaded into the main control board through the management computer. When the temporary visitor leaves, the card can be returned and the permission of the temporary card can be cancelled.
5. Security card management. For one-time visitors or some visitors, the security floor can be swiped by the security guard to open the elevator floor. The security card's permissions can also be authorized by the administrator.
6. The situation of one ladder and two doors. The access control hardware reserves the interface of two card readers. In some elevators with double-sided opening, the card reader can be installed at both ends, which is more convenient to use.
Optional function
1. Intercom linkage function. When the visitor calls the occupant through the intercom door host, after the occupant confirms, the occupant opens the door from the indoor intercom extension, and connects to the intercom system through the input conversion board of the access control, that is, when the intercom system opens the door, the elevator is called to the floor. And providing the floor number of the called household to the main control board, the main control board is the button for controlling the floor, the visitor enters the elevator and then presses the corresponding floor button, and the elevator only reaches the floor.
2. Call control function. Install the call controller next to the elevator's up and down call buttons. After the card is valid, the button can be pressed, no card or invalid card is swiped, and the buttons are not reflected, preventing illegal users from calling the elevator.
The elevator should not be scrapped, after reading this will understand
2015-09-08
As of the end of 2014, the number of elevators in China has more than 3500000 units, the amount of production, ownership, annual growth of the world's first. However, with the increase of the number of elevators, the old elevator running for many years also increased rapidly, and the safety risk caused by the functional degradation of the elevator components has increasingly been concerned by the society.
July 20th, the National Standards Committee held a media briefing, invited experts to the new release of the main parts of the elevator, the technical conditions of the national standards for interpretation.
Why to develop this standard
Because of the influence of the design, manufacture, installation, maintenance and use, there is a big difference in the service life of the elevator. It is difficult to establish the standard of the elevator. At the same time, the transformation and upgrading of the old elevator, but also the relevant departments are very "headache" one thing: a huge cost and management difficulties.
Therefore, by setting up the main parts of the elevator to scrap the technical conditions, the decision to scrap or not, and then determine whether the elevator is required to scrap, is to improve the safety in the use of the feasible way, taking into account the economic and scientific.
Currently the only relevant standards in the world
This standard is independently developed by our country, there is no relevant international standards, developed countries have no relevant standards. The standard filled in the domestic and foreign elevator industry for many years the lack of elevator related standards, the new standard will be formally implemented in February 1st next year.
13 major component technology
The new standard stipulates the "safety protection device, emergency rescue equipment, safety door in well and the trapdoor, drive host, car, layer door and the car door, an electrical control device and 13 on the safe operation of the elevator influence large elevator main parts scrapped technology conditions. Standard clear mechanical damage (such as cracking, deformation), non normal wear and tear, corrosion, material aging, electrical failure, electrical components damage and other 6 kinds of failure or potential failure mode as part of the technical conditions for the existence of risk, the need to scrap parts to provide a technical basis. To improve the operation safety and service life of the elevator, the main component of the failure or potential failure risk of the main components of the elevator to promote the upgrading and transformation.
Effectively avoid serious accidents
As the key part of the elevator, the brake can be used as the core of the electromagnetic coil, which can lead to the phenomenon of the brake, which is easy to lead to serious safety accidents such as the lift truck, the pier bottom, and the top of the head. The standard of the brake solenoid coil iron core action exception, the phenomenon of card resistance phenomenon as a brake scrap technical conditions, will greatly reduce the risk. Hanging wire rope as elevator traction and bearing components, carrying the car with the load and the weight, and the realization of the traction drive. Rope suspension deformation or damage will not only lead to wire rope inner stress distribution is not uniform, accelerate the damage of steel wire rope, but also to the traction wheels and pulleys caused abnormal damage and accelerated damage. Standard wire rope cage shape distortion, strand extrusion, kinks, part flattened or curved fold "appears as the traction steel wire rope and the hydraulic elevator suspension rope scrap technical conditions of, will be effective to avoid the above problems.
The national standard of the national standard for the technical conditions of the main parts of the elevator
