How to troubleshoot product problems with QR code access control? Cyberlos Technology teaches you a few tricks
Customers are afraid of product quality problems when purchasing products, so they will choose a number of products to borrow samples to ensure the quality of the product and the suitability of the product function . Before the products of Sebreros are out of the warehouse, they will undergo aging tests and product troubleshooting Waiting for multiple tests, so Sebreros said here how to troubleshoot the product?
1. Software Testing Method
1. Detection method: Start the management software, enter the main console to select the door, click the detection controller, the software operation information will prompt related faults, then you can deal with it according to the relevant information.
2. Real-time monitoring method: total console-real-time monitoring, real-time monitoring corresponding to the corresponding card indicator light is convenient to detect the failure of card opening.
3. Web search method: basic setting-controller-search web page t, help to find communication faults of TCP / IP controller. Corresponding communication indicator helps to find communication faults. Please turn off the firewall!
Second, the hardware indicator method
1. When power is on, we can look at the power indicator POWER and the CPU indicator flashes to determine whether the controller is in working condition.
2. When swiping the card, we can look at the card light to determine whether there is card reading data transmitted to the controller.
3. Press the exit button, we can see whether the relay indicator light clicks to determine whether the controller relay output is normal.
4. Look at the TX and RX lights during the communication operation. The TCP controller Rx (Link) light is always on to indicate that there is no problem with the wiring. Tx light flashing indicates that communication is in progress.
5. The flashing of the err light indicates that the controller is malfunctioning. Obtain detailed information in the software.
6. The video controller can also look at the power indicator. Whether the Rj45 port indicator flashes alternately during ping.
7. Whether or not the 485 active converter flickers can determine whether the computer is sending data.
Three, replacement exclusion method
1. Equipment replacement method: This can only be used for reference and cannot be completely determined, because if it is caused by an environment or factor, it may not be immediately displayed, just like a chronic disease of humans has an incubation period, and over time will also cause problems It appears that if the equipment that is suspected of being replaced is detected separately and there is no problem, this may be an environmental interference problem such as wiring, and it should actively continue to find the source of the fault.
2. Computer replacement method: It can determine whether it is the customer's computer or operating system environment, virus problems, serial port output or settings are incorrect.
3. Database and software replacement method: For example, failure to extract records or upload settings, failure to generate reports, etc., you can use another brand-new database or software to determine the scope of the problem.
4. Separation and elimination
1. With the access 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, resulting in strange phenomena, such as controller restart, ERR light Blinking, the door opens and closes abnormally, you can separate this external device to see if it is normal, and then load each external device one by one, and load a test to see what is loaded to cause this failure, such as three stick gate, barrier gate, electric bell , Elevators, automatic doors, and various alarm devices external to the expansion board may all be sources of interference. The solution is to install a weak current isolator.
2. In the 485 communication mode, there are 8 controllers in a system. You can consider disconnecting the next 4 units first, and then disconnect the remaining 2 units to narrow the search range, or disconnect from the second one first. Connect the following links to the communication lines one by one to see which one will not work.
3. The TCP controller cannot use the conventional method to connect to the customer's network normally. You can test the OK from an independent switch independently from the customer's network and seek support from the network management of Party A to see if other network authentication restrictions are enabled.
These are the troubleshooting methods for some products, if you have any questions or product consultation, can go to Cybertron Ross officer wang consult customer service, we will assign you to an exclusive pre-sale technology for you based on your needs.
