The wireless communication system of the Tongkuai high-speed bending machine is a key link connecting the CNC system, operation panel, external sensors, and automation unit. Once a fault occurs, it may cause the equipment to shut down, parameter transmission to be interrupted, or automation functions to fail. Such faults are often related to signal transmission, hardware status, and system configuration, and need to be gradually resolved through layered troubleshooting and targeted operations.
Basic troubleshooting is the first step in troubleshooting, and priority should be given to eliminating external environmental and simple configuration issues. Firstly, check the power supply status of the wireless communication module and confirm whether the module power indicator light is on normally. If the indicator light goes out or flashes abnormally, check whether the power supply circuit is loose, whether the fuse is blown, and replace damaged power supply components in a timely manner. Next, check the network connection status by accessing the "Communication Settings" interface of the bending machine CNC system to see if the wireless connection has been established and if the IP address is in the same network segment. If there is a connection interruption, try searching for the wireless network again and entering the correct password. At the same time, turn off nearby devices that may cause interference (such as high-frequency welding machines and high-power frequency converters) to avoid electromagnetic signals affecting wireless communication.
Signal optimization is the core means to solve communication instability. If the device has problems such as "intermittent communication" and "data transmission delay", it is necessary to first check the status of the wireless antenna: confirm that the antenna is installed firmly, without bending or damage, and if necessary, replace it with an antenna of the same model to enhance signal reception capability; If the distance between the bending machine and the wireless AP (access point) is too far or there is wall obstruction, the AP installation position can be adjusted to shorten the signal transmission distance, or signal repeaters can be added to expand the coverage range. In addition, it is necessary to enter the wireless module configuration interface to check the channel occupancy and switch the communication channel to a frequency band with less interference (such as channels 1, 6, and 11 in the 2.4GHz frequency band) to reduce signal conflicts with devices on the same frequency band.
Hardware and system debugging are key to handling deep faults. If the problem is still not resolved after basic troubleshooting and signal optimization, the wireless communication module itself needs to be checked: replace the faulty module with a backup module through replacement method. If communication is restored to normal, it indicates that the original module has hardware damage and needs to be repaired or replaced by contacting the manufacturer; If the fault persists after replacing the module, it is necessary to check the communication parameters of the bending machine CNC system, confirm that the baud rate, data bits, stop bits and other configurations are consistent with the wireless system, and avoid data transmission errors caused by parameter mismatch. In addition, it is necessary to check the system software version. If there are compatibility issues, the firmware of the CNC system and wireless module can be updated through official channels to fix known communication vulnerabilities.
After the fault handling is completed, stability testing is required: continuously transmit multiple sets of bending parameters, observe whether the data reception is complete, and run the equipment for continuous bending operations to confirm that communication is not interrupted. By establishing a regular inspection mechanism, cleaning wireless modules and antennas on a weekly basis, and checking communication parameters on a monthly basis, it is possible to effectively prevent the recurrence of wireless communication failures and ensure the continuous and stable operation of the high-speed bending machine.
