Industrial tablet PCs will inevitably have some failures during operation. When the industrial tablet PC crashes, how to solve it? Let's first understand what causes the industrial tablet computer to crash?
1. Poor internal heat dissipation of industrial tablet computers
Industrial tablet computers are in a harsh environment, in addition to high temperature, there is also a lot of dust. When dust enters the industrial tablet computer, the heat dissipation effect of various boards, CPUs and other electronic components is poor, causing the industrial tablet computer to "crash".
Solution: Clean the dust inside the industrial tablet computer regularly and maintain good ventilation.
2. Ambient temperature
Industrial tablet computers are more sensitive to ambient temperature. When the summer is hot and the air conditioner is damaged, industrial tablet computers are prone to "crash".
Solution: Repair the air conditioner, lower the ambient temperature of the industrial tablet computer, and ensure the normal operation of the industrial tablet computer.
3. Frequently clean up temporary files
When the industrial tablet computer is running, it will generate a large number of temporary files. These files occupy the hard disk and system resources and affect the speed of the industrial tablet computer to process information.
Solution: Check the hard disk regularly and delete temporary files to improve the speed of industrial tablet computer processing information.
4. Hardware reasons
When the industrial panel computer processes too many on-site signals transmitted by PLC, the CPU efficiency of the industrial panel computer is low, and the memory is small, and it cannot recognize and process so many signals at the same time. These signals "crash" and cause the industrial panel computer to "crash". ".
Solution: Due to the limitation of the memory slot of the industrial panel computer motherboard, intelligently expand the memory to 64M. The main solution is to reduce the frequency of processing and identifying on-site signals by industrial tablet computers to avoid signal "car crashes". The specific plan is: when the industrial panel computer is connected to the field signal through the PLC, the signal sampling period is set to be more than 2s, and the analog signal with little change, such as temperature, can be set to more than 10s. In the process of programming, after setting the sampling period of all analog signals to more than 2s, the phenomenon of industrial panel computer "crash" rarely occurs.
5. Check the CPU fan and host power supply fan
The heat dissipation of industrial tablet computers is mainly carried out by CPU fans and power supply fans. When the CPU fan is damaged, the temperature of the CPU rises, which can easily cause the industrial panel computer to "crash".
Inspection method: frequently check the fan of the industrial panel computer, and replace the damaged fan in time. When the industrial panel computer in the central control room leaves the factory, only a heat sink is installed in the CPU, without a fan, and a special cooling fan is installed later, and the temperature of the CPU is reduced by nearly 5 degree .
The above are the reasons for the possibility of crashes in industrial tablet computers. In general, in addition to correct operation, necessary maintenance is also required. Also pay attention to the temperature during use, and often clean up temporary files, pay attention to these matters. It can reduce the occurrence of "crash" of industrial tablet computers.
