Overview

The automatic control system of elevators is implemented through BAS for centralized management and control programs of multiple elevators in the building, while cooperating with some subsystems of BAS to execute linkage programs.

Feature Introduction

Group control function of elevator group

The centralized control of multiple elevators is particularly important. When a user on any floor calls the elevator The elevator in the same direction as the user will be the first to reach the user's call floor to save waiting time. The group control management program for elevators can automatically detect the busy level of elevator operation, control the number of open/stop elevators, and save energy. At the same time, through the system management center, the operating status of each elevator is directly monitored on the CRT graphic display. When an elevator malfunctions, an alarm signal is sent to the system management center.

Security management function of elevator group

The management of elevators leading to key department floors within the main building is particularly important. The smart card system can be used to implement comprehensive security management for the elevator group in the building. Set the elevator operation schedule using the SAS system in the building and a time control program, for example, the program can set 19:00

--

8: 00, all access doors on key department floors are automatically locked (in case of a fire alarm, the access door will automatically open), so that the access doors on the upper and lower floors can be locked The passage is the elevator. At the same time, the program can be set to stop most elevators from running (due to non peak hours). In this way, all personnel entering the floor must hold a smart card pass in order to enter and read the card. The elevator card reader will automatically operate to the designated floor according to the security level preset in the smart card or the designated floor. At the same time, the system management center will record the names, times, and floors of the personnel using the elevator, and the elevator camera will synchronously capture the cardholder's image (to prevent tailgating). If the personnel entering the floor do not hold a smart card pass, it is impossible to enter the floor. When the cardholder leaves the building and calls the elevator, the elevator will automatically come to that floor and can only return At the same time, the system management center will record the return time and cardholder name.

Linkage function of elevator group

When an abnormal event occurs in a building, the elevator team often needs to take corresponding linkage actions, because IBMS/BMS is an integrated management system with multiple subsystems, which can easily handle linkage programs when multiple events occur. For example, when there is a fire alarm, the linked elevator group will descend to the bottom floor of the building; When an anti-theft alarm signal occurs, the elevator will stop at the designated floor of the program or not stop at the corresponding floor of the alarm point. In short, through the system management center, various emergency events and elevator group linkage programs can be set according to needs and linkage logic.

In this system, the building controls the elevator system according to a pre programmed program, and the specific monitoring functions are as follows:

1. Confirm whether the equipment is currently under the control of the building automation system, while reducing the false alarm rate of fault alarms;
