With the continuous popularization of industrial panel PC applications, more and more enterprises are gradually using it. It is inevitable that some faults will occur during the operation of the panel PC.
When the industrial panel PC crashes, how can we solve it? In order to solve the problem, we must first find and understand the cause of the problem.
1. Poor internal heat dissipation performance
Due to industrial panels computers are mainly used in harsh environments. Except for the high or low-temperature conditions, there is also a lot of dust. When dust enters the industrial panel PC, it will affect the heat dissipation performance to the CPB boards, CPUs, and other electronic components, resulting in the "crash" of the panel PCs.
Tips: regularly clean the dust inside the industrial panel PC, and keep it well ventilated.
2. Redundant temporary file
When the industrial tablet PC is running, it will produce a large number of temporary files, which occupy the hard disk and system resources and affect the speed of information processing, sometimes it would cause crashes.
Tips: Regularly check the hard disk and delete temporary files to improve the speed of information processing.
3. Too much data and low CPU efficiency
When the industrial panel PC processes too many field signals transmitted by PLC, the CPU efficiency of the panel PC is low and the memory is small, so it is unable to identify and process so many signals at the same time, which makes these signals "crash", resulting in the "crash" of the industrial panel PC.
Tips: due to the limitation of the memory module slot on the main board of an industrial panel PC, usually the memory is only expanded to 64M. The main solution is to reduce the frequency of industrial tablet computers' processing and identify field signals to avoid signal "crashes".
Let's take the industrial panel PC used on industrial sites as an example: when the industrial panel PC is connected to the field signal through PLC, set the signal sampling period to more than 2S, and set more than 10S for analog signals with little change, such as temperature. In the programming process, after setting the sampling period of all analog signals to more than 2S, the phenomenon of "crash" of industrial panel PC rarely occurs.
4. CPU's fan and the host power supply's fan are damaged
The heat dissipation performance of industrial panel PC is mainly carried out through CPU fan and power fan. When the CPU's fan is damaged, the temperature of the CPU rises, which is easy to cause the "crash" of the industrial panel PC.
Tip: Regularly check the fan of the industrial panel PC and replace the damaged fan in time. Some industrial panel PCs are engineered only equipped with a heat sink without a fan in the CPU system. After a special heat dissipation fan is installed, the temperature of the CPU is reduced by nearly 5 ℃.
The above are the possible reasons for the crash of industrial tablets. Generally speaking, in addition to correct operation, necessary maintenance is also required. In the process of use, pay attention to the temperature, regularly clean up temporary documents, which can reduce the occurrence of "crashes" of industrial tablets.
There are two main reasons for the "crash" of industrial tablet computers, that is motherboard failure and system failure. As the most basic and core part of hardware and software, their application is very important. Therefore, this requires us to follow the precautions and timely repair and maintenance when we use it at daily times.
