With the continuous popularization of industrial tablet PC applications, more and more companies are gradually introducing their use. During the operation of the equipment, there will inevitably be some failures. When the industrial tablet computer Crashes, how should we solve it? If you want to solve the problem better, you must first find out the cause of the problem. Follow SINSMART to find out what causes the industrial tablet computer to crash!
1. Poor heat dissipation inside the industrial panel computer
The environment in which industrial tablet computers are located is relatively harsh, 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, CPU and other electronic components is poor, causing the industrial tablet computer to Crash.
SINSMART Reminder: Regularly clean the dust inside the industrial tablet and keep it well ventilated.
2. Frequently clean up temporary files
When the industrial panel computer is running, it will generate a large number of temporary files, which occupy the hard disk and system resources, and affect the speed at which the industrial panel computer processes information.
SINSMART Reminder: Regularly check the hard disk and delete temporary files to improve the speed of information processing by industrial tablets.
3. The amount of data is too large and the CPU efficiency is low
When the industrial panel computer processes too many on-site signals transmitted by the PLC, the CPU efficiency of the industrial panel computer is low, and the memory is small, so it cannot recognize and process so many signals at the same time, causing these signals to Crash and cause the industrial panel computer to Crash.
SINSMART Reminder: Due to the limitation of memory slots on the main board of industrial tablet PCs, Smart expands the memory to 64M. The main solution is to reduce the frequency with which the industrial panel computer processes and recognizes on-site signals to avoid signal Crash.
The specific plan is: when the industrial panel computer is connected to the field signal through the PLC, set the signal sampling period to more than 2s, and set it to more than 10s for analog signals that do not change much, such as temperature. In the programming process, after setting the sampling period of all analog signals to more than 2s, the Crash phenomenon of the industrial panel computer rarely occurs.
4. Check the CPU fan and host power fan
The heat dissipation of the industrial panel computer is mainly carried out by the CPU fan and the power supply fan. When the CPU fan is damaged, the temperature of the CPU will rise, which will easily cause the industrial tablet computer to Crash.
SINSMART Reminder: Check the fan of the industrial panel computer frequently, and replace the damaged fan in time. When the industrial tablet computer in the central control room leaves the factory, the CPU is only equipped with a heat sink, without a fan. Later, a special cooling fan is installed, and the temperature of the CPU is reduced by nearly 5°C.
The above are the possible reasons for the crash of industrial tablet computers. In general, in addition to correct operation, necessary maintenance is also required. During use, we must also pay attention to the temperature, and we must often clean up temporary files. Pay attention to these matters, It can reduce the occurrence of industrial panel computer Crash.
There are two main reasons for the Crash of daily industrial tablet computers, board failure and system failure, as the most basic and core part of hardware and software, their application is very important. So this requires us to follow the precautions and maintain it in time when we usually use it.
