Basic understanding of access control gates

The identification device from the controller to the terminal is a mature and stable product. As the core of the system, the access control gate needs to support the offline working mode. The power failure or the impact information will not be lost. The server and terminal identification equipment failure will not affect the normal system. run. The main equipment should adopt modular design and adopt advanced wiring method. It can realize future system expansion through software and hardware upgrades without having to make too much changes to the system, embody economic principles, and the products should be cost-effective.
The channel gate has the self-adaptive ability when abnormal conditions occur. When the communication with the management terminal is interrupted, the normal opening of the field channel gate is not affected. The management host can cancel the authorization, and various event data reports can be provided, including the cardholder. Incoming events, alarm events, system events, etc.; the system can log the manager's operation steps, allowing traffic, refusal of traffic, alarm, forced opening, normally open, fault, network connection, network disconnection, remote control, etc. The system has a special memory protection device, and the access control code and system data will not disappear due to power failure.
If maintenance and maintenance are not in place and there is a failure to repair on site, it will be the loss of the unit. Before the installation of the fully automatic three-roller gate, the no-load current of the motor should be less than 500 mA, and the starting distance of the motor is in accordance with the use. It is required to install the fully automatic three roller gate at the rear. This little detail needs attention. Before the door-opening gate is powered on, the equipment must be inspected to ensure that the mechanical parts are not stuck and operate flexibly. If there is no problem in the electronic control part, check whether the power supply is exposed, and wrap it with the wire protection tool, arrange the wire, replace the wire in time, refer to the manual of the gate, check the parameters of each part, have problems in the electronic control part, check each component in turn, and find it in time. At the root of the problem, replace individual electronic components.
