Access control turnstile door system is widely used in modern commercial buildings, communities, schools, enterprises and other security management systems. Access control turnstile door system is a latest security management system, which combine computer automatic identification technology and modern security management measures. Access control turnstile door with affordable price is widely used in our life and work, but how much do you know about daily maintenance of access control turnstile door system? Let's share the relevant content of troubleshooting the system of access control.


Software testing method

1. Detection method: start the management software, enter the main console, select the door, click the detection controller, the software operation information will prompt the relevant fault, then it can be processed according to the relevant information.

2. Real time monitoring method: the main console - real-time monitoring, real-time monitoring corresponding swipe card indicator light, convenient to find out the swipe card does not open the door fault.

3. Search. Net method: basic setting - controller - Search. Net is helpful to find the communication fault of TCP / IP controller, and the corresponding communication indicator is helpful to find the communication fault. (Note: please close the firewall! )


Hardware indicator method

1. When power on, we can see the power indicator power, CPU Indicator Flashing to determine whether the controller is in working state.

2. When swiping the card, we can look at the card light to determine whether the card reading data is transmitted to the controller.

3. Press the exit button, we can see whether the relay indicator light clicks, and judge whether the relay output of the controller is normal.

4. During the communication operation, look at the TX and Rx lights. The RX (link) light of the TCP controller is always on, indicating that there is no problem with the wiring. The TX light flashes to indicate that communication is in progress.

5. Err light flashing indicates that the controller has failed, and the detailed information can be obtained in the software detection.

6. The video controller can also see whether the power indicator light flashes alternately when pinging.

7. Whether the 485 active converter flickers or not can determine whether the computer has data transmission.


Substitution exclusion

1. Equipment replacement method: this method can only be used for reference, but can not be completely determined, because if it is caused by certain environment or factors, it may not appear immediately, just as there is an incubation period for people's chronic diseases. After a period of time, it will also cause problems. If the replaced equipment is suspected of having problems, there is no problem in the separate detection, it may be environmental interference problems such as wiring, We should actively continue to find the source of the fault.

2. Computer replacement method: can determine whether the client's computer or operating system environment, virus problems, serial output or set the wrong.

3. Database and software replacement method: for example, if the record extraction or upload setting fails, or the report generation fails, another brand-new database or software can be used to determine the scope of the problem.



Separation and exclusion

1. With the system of access control controller as the core, many controlled devices can be connected, and the quality parameters and performance of the external devices are uneven. If they are compatible, there may be interference, and the phenomenon will be strange, such as the controller restart, err light flashing, abnormal door opening and closing, the external devices can be separated to see whether they are normal, and then each external device can be loaded one by one, and the Take a test to see what causes the fault. For example, three bar gate, road gate, electric bell, elevator, automatic door, and various alarm devices connected to the expansion board may be the interference source. The solution is to install weak current isolator.

2. 485 communication mode, a system has eight controllers, you can consider first disconnect the following four, and then disconnect the remaining two to narrow the search range, or disconnect from the first two, one by one link the following to the communication line, to see which one can not be added.

3.If the TCP controller can't connect to the customer network normally by using the conventional method, it can be separated from the customer network and tested OK with the independent switch. Then it can seek the support of Party A's network management to see whether other network authentication restrictions are enabled.

The daily maintenance of access control turnstile system is also a very important part. To ensure the normal use of the security turnstile door equipment, we must understand these daily detection methods. In this way, we can better ensure the safety and effective personnel management of our place and area.

The above is about the 4 methods of access control turnstile door system troubleshooting related content, I hope to help you in the daily maintenance of access control turnstile door.
