As the core equipment of industrial control, industrial controllers play a key role in industrial automation, equipment monitoring, data processing and other fields. However, industrial controllers may encounter a variety of faults during long operation. This article will introduce some common industrial computer failure and its elimination methods to help users quickly locate and solve the problem.
First, can not be turned on
Failure phenomenon: industrial computer press the power button, no response, can not boot.
Troubleshooting methods:
1. Check the power supply: make sure whether the power plug is plugged in tightly and whether the power cord is damaged. Try to replace the power socket or use a multimeter to test whether the power output is normal. 2.
2. Check the power button: Sometimes the power button may be damaged or stuck, resulting in failure to turn on the power. Try gently tapping or pressing the power button to see if it returns to normal.
3. Check the internal hardware: If the power supply is normal, the internal hardware may be faulty. You can open the chassis and check whether the memory sticks, hard disk, etc. are plugged in properly and whether there are signs of damage or looseness.
Second, blue screen or crash
Failure phenomenon: industrial computer in the operation process suddenly appeared blue screen or crash phenomenon, can not operate normally.
Troubleshooting methods:
1. Check the heat: poor heat dissipation is a common cause of blue screen or crash. Check whether the fan of the industrial computer is running normally, whether the heatsink is clean and dust-free. 2.
2. Update the driver: incompatible or outdated drivers may also lead to failure. You can try to update the drivers for your graphics card, sound card, etc. to the latest version.
3. Check memory: Memory problems are also a common cause of blue screens. You can use the memory detection tool to detect the memory to see if there is any error or damage.
Third, network connection problems
Failure phenomenon: industrial control machine can not connect to the network, or network connection is not stable.
Troubleshooting methods:
1. Check the network cable: make sure that the cable is plugged in properly and is not damaged. You can try to replace the network cable or network interface to see if it can return to normal. 2.
2. Check the network settings: Check whether the network settings of the ICPC are correct, including the Ip address, subnet mask, gateway, etc. 3.
3. Check the network equipment: If all the above are normal, the network equipment (such as switches, routers) may be faulty. You can try to restart the network device or replace the device for testing.
Fourth, hard disk failure
Failure phenomenon: industrial control machine can not recognize the hard disk, or hard disk read and write speed becomes slow.
Troubleshooting methods:
1. Check the hard disk connection: confirm whether the hard disk data cable is plugged in, whether there is damage. You can try to replace the data cable or interface to test. 2.
2. Check the status of the hard disk: use the hard disk detection tool to test the hard disk to see if there are bad sectors or damage. If there is any damage, you can try to repair or replace the hard disk.
3. Update BIOS: Sometimes the BIOS version is too old and may cause hard disk recognition problems. You can try to update the BIOS to the latest version.
Other Common Failures
In addition to the above several common failures, industrial computer may also encounter sound card, USB interface failure, no signal display and other problems. For these failures, you can generally check the device connection, update the driver, replace the hardware and other methods to eliminate.
In order to avoid the occurrence of industrial computer failures, it is recommended to perform regular maintenance and repair. This includes cleaning the chassis, checking hardware connections, updating software and drivers, and so on. At the same time, keep the temperature and humidity of the working environment appropriate, and avoid overuse or prolonged continuous work.
In short, although the common faults of industrial control machine are varied, but as long as you master the correct troubleshooting methods, you can quickly locate and solve the problem. In daily use, pay attention to the maintenance and maintenance of industrial control machine, can effectively extend its service life and improve work efficiency.
