Chapter 1 Preface
The intelligentization of residential quarters is the need of social development and the product of economic and technological development. Since the reform and opening up, under the premise of rapid economic development in our country, a historic breakthrough has been made in housing construction. With economic development, people’s lives have become richer, most people have houses to live in, and a considerable number of people have begun to pursue a comfortable and safe housing environment. Housing construction has also shifted from the pursuit of “quantity” to “quantity” and “quality”. This is also the development trend of the entire international society. The housing environment must rely on high technology to achieve. At present, the construction of intelligent housing has been put on the construction schedule.
The design of the smart residential community card system is characterized by an advanced application system that combines contemporary advanced non-contact smart card technology with computer communication technology and database application technology. As a one-card management system for residents, it can realize the integration and automation of property management, building access, registration, query, elevator control, parking management, area shopping, entertainment consumption, billing, checkout, statistics, etc. in residential quarters.
From the perspective of the purpose of the one-card system, the community one-card system can generally be divided into two parts, one is the community security one-card, and the other is used as an electronic wallet application. At present, almost all residential communities in large, medium and small cities are equipped with a community security card system, and its subsystems include access control, elevator intelligent control, electronic patrol, parking management, and so on. And as a consumer system for electronic wallet applications, it is slowly becoming popular in smart communities. The elevator intelligent control system, as a new IC card intelligent control system, is becoming “popular” in high-end residential quarters and office buildings. On the one hand, it is an intelligent application system integrating non-contact IC card technology, automatic control technology, and computer application. It fully meets the high security requirements of high-end residential quarters or office buildings, and it can deny outsiders entering at will Inside the building, cardholders can also be restricted to only reach the floor where they are located, which is more effective than any previous means to prevent the residence or office area in the building from being harassed by outsiders; on the other hand, due to its own control Principle, it is an intelligent system completely independent of the elevator’s own control system. Its design and construction do not require complicated changes to the original elevator system, only simple wiring is required at the button panel in the elevator car. It can realize the use of IC card to control the elevator. Therefore, it can be applied to elevators in any building, regardless of whether the elevator has been put into use, it can be easily modified and opened for use.Moreover, when the IC card control system fails, just stop the IC card controller power supply, and the elevator can return to its normal operation.
Chapter Two Brief Introduction of IC Card Elevator Control System
Many high-end buildings are now equipped with IC card elevator control systems. The owner holds the IC card and swipes the card to enter the lobby door. At the same time, the elevator is summoned to the first floor or the elevator has the first floor waiting function. After entering the elevator, swipe the card in the car, IC The card elevator control system will activate the corresponding button of the elevator car control keyboard, and it will transport you to your floor.
Chapter 3 IC Card Elevator Control System Analysis
In response to the above needs, Jianbo Electronics Co., Ltd. has launched the JBC2132 elevator control system. In this system, all cardholders who use elevators must first be authorized by the system administrator. When using elevators, different people have different authority assignments. Each person who enters the elevator can enter the designated area or floor with authorization, and can perform authorization management according to the timetable. Without authorization, it is impossible to enter the management floor, and to control the time of important floors. Regardless of whether the controller is running offline or online, it can record a large amount of transaction data, so that all the elevator personnel entry and exit records can be found.
1. The working principle of JBC2132 IC card elevator control system
The working principle of elevator control is by intercepting the elevator control panel, and directly connecting the elevator buttons or the reserved IC control interface of the elevator to the output terminal of JBC2132. In the normal power-on working state, the output terminal is in a live open circuit state. At this time, the elevator button Cannot work normally; when the card reader reads a valid card, the corresponding output terminal is restored to the connected state, and the elevator floor button is pressed at this time, and the elevator logic controller receives the corresponding floor request signal and starts to run.
2. Hardware introduction of JBC2132 IC card elevator control system

3) Input and output of JBC2132
Controller output relay: The output terminal relay is open when it is working normally. When it is forcibly closed by the external card reading signal when it is allowed to work, the circuit is closed, a state change occurs, and the relay outputs a short circuit signal Control the corresponding elevator floor work. The elevator controller relay is a normally open contact when it is energized. When the relay is not energized and controlled, the normally open contact is connected; once the relay is energized, the normally closed contact is disconnected, and the elevator’s work is controlled at this time The validity of the card reading.
Card reader interface: The card reader interface of the elevator controller is a standard RJ45 socket with a total of 8 wiring heads, which are used to receive external effective signals, and then open the corresponding output terminals, allowing them to be in the set time Work. Generally, the distance between the external card reader and the controller card reader interface is not allowed to operate more than 100 meters, and should be connected with a Category 5 8-core shielded twisted pair cable.
RS485 network interface: The network interface of the elevator controller adopts a half-duplex RS-485 communication bus system, usually using Category 5 2-core shielded twisted pair connection, and the communication distance can reach 1200 meters.

3. The realization function of JBC2132 IC card elevator control scheme
1) Networking mode: The elevator equipment in this scheme adopts RS485 networking mode to ensure the safety and reliability of the entire system, which is conducive to the unified management of the entire system.
2) Control the number of floors: each elevator controller can control up to 4 elevator control expansion boards, each elevator control expansion board can control up to 8 floors, that is, each elevator controller can control up to 32 floors, through expansion The elevator controller can realize unlimited levels of control.
3) Card function: The elevator system uses a non-contact IC card. When the card is lost, it can be easily reported or replaced on the management software to prevent the card from being used illegally after being picked up by an illegal user.
4) Temporary card function: With the authorization of the management center, temporary cards with different permissions can be set in advance (temporary cards are generally set to the interviewee’s floor). When the customer visits, the management staff provides the temporary card and records the customer’s detailed information. The card is taken back when the customer leaves. All temporary card entry and exit have detailed records.
5) Recording function: The elevator system has a comprehensive event record storage function. The types of events that can be recorded are: normal card swiping events, abnormal card swiping events, each event records the name of the person, the time of swiping the card, the elevator room and other information in detail, combined The computer can inquire about the occurrence time of specific events and the person in charge, and implement responsibilities.
6) Delayed release function: After swiping the card, the user must press the floor button within the specified time (1~255 seconds can be set), and the button will be automatically released after the timeout to prevent illegal users from illegally using the elevator.
7) Remote control function: Managers can remotely control the turn-on and turn-off of elevator floors through the network. For example: a user forgets to bring his card that day, and after calling the management office to confirm his identity, the management personnel remotely connects to the user’s floor buttons. There are a lot of people during the on and off hours, and it is inconvenient to swipe the card. The management staff can set the elevator to be normally open (all buttons are connected), and it will be restored to the state of swiping in and out after the peak period. Each button can be set to normally open state (long-term on) or delayed state (off after delay), which makes the elevator operation more flexible and the control more standardized.
8) Time limit function: When using the elevator, different people can set different valid time for swiping the card, and swiping the card will be considered invalid after the allowed time. For example, the valid time of user A’s card swiping is set from 8:00 in the morning to 18:00 in the evening. During this period, user A can use the elevator normally, and will not be allowed to use the elevator after the timeout.
9) Authority function: When using the elevator, different people have different authority assignments. Each person who enters the elevator can enter the designated area or floor with authorization. After the user swipes the card, the floor button with the corresponding authority is activated, and the user can select the floor. For example: User A is allowed to enter the floors 1, 3, and 4. After swiping the card, the buttons on the floors 1, 3, and 4 of the elevator panel are turned on and the lights are on, and the other buttons remain off. Each card can set the expiration date independently, for example: User A’s card is valid from August 3, 2006 to August 5, 2006, and User A’s card is invalid after August 5, 2006.
10) Safety function: The elevator system adopts a split structure design that fully meets the security product specifications, that is, the card reader part is separated from the elevator control part. When the event server in the elevator system loses communication with the management host, it can work offline through the information stored in the event server without affecting any operation. The elevator controller and the elevator itself are connected by passive contacts (dry contacts), and the two are completely isolated, which will not have any impact on the original performance of the elevator.
11) Fault isolation function: Elevator controller provides normally open and normally closed dry contact output, generally using normally open dry contact connection. In the event of a power failure or failure of the elevator, all output nodes are automatically disconnected to ensure the safety of personnel in the elevator, and the elevator is at a standstill at this time.Fire interface function
12) Management software function: The intelligent elevator control system software platform adopts modular design, and its interface is basically icon button display, easy to operate, just use the mouse to tap the button on the interface to complete most of the system settings and data collection And so on. Its management function is powerful, which can realize real-time monitoring of elevator running status.
