Various fault repair methods for the controller of key parts of the speed gate

Speedway doors can be seen in subway stations, airports, schools, exhibition halls and scenic spots. However, due to the high frequency of opening and closing of the speed gate controller in daily use, some common faults will occur, so how to deal with the common faults of the speed gate controller?
1. The maintenance method of the speed gate controller caused by the communication connection:
If there is a communication connection failure in the speedway door controller, you can first check whether the serial port is set incorrectly, and then check whether there is a short circuit or open circuit in the communication bus of the speedway door access control. If the controller still has a communication failure, you should check the communication card or the communication chip to see if the communication connection failure is caused by the communication chip;
2. Troubleshooting methods for the speed-pass door controller due to the failure of the speed-pass door access control card:
Usually, when using the speed pass door controller, it will be equipped with a speed pass door access control card. By scanning the speed pass door access control card, the speed pass door flap will be opened, but if the speed pass door controller is used daily, the speed pass door will suddenly appear. If the door access control card fails to be read, it is necessary to check whether the speed pass door controller has voltage signal output after the card is read. If it is not a signal fault, then you should check whether the external relay or the speed pass access control card authority is faulty;
3. The fault repair method of the speed-pass door controller due to the disordered storage parameters of the speed-pass door access control board:
Because the speed pass door controller is a commonly used device, and it comes into contact with a lot of speed pass door access control cards or electromagnetic interference every day, the speed pass door controller may also have a fault that the speed pass door access control keeps beeping. The main reason may be the speed pass door. It is caused by the disordered storage parameters of the access control board, so it is necessary to modify the parameters of the express door controller, and check whether the read-write chip and the read-write module of the card-reading board are damaged;
The above-mentioned faults are prone to occur when the speed gate controller is in high-load use every day. If you have certain maintenance skills, you can first judge and try to solve the problem according to the maintenance solutions of the speed gate controller provided in the article. If you still can't solve the fault of the speed gate controller, you should contact the speed gate repair company of the revolving door for maintenance as soon as possible.
