Some Points about Industrial Tablet Computer cannot Work
With the continuous popularization of industrial tablet applications, more and more enterprises gradually introduce its use. And equipment in the process of operation, it is inevitable that there will be some failures, when the industrial tablet computer “crash”, how should we solve it? To better solve the problem, first to find the cause of the problem, follow Symtrue together to understand the cause of industrial tablet computer crash what it!
- Poor internal heat dissipation of industrial tablet computers
Industrial tablet computers are in a harsh environment, in addition to high temperature, dust is also a lot. When the industrial tablet computer into the dust, all kinds of board cards, CPU and other electronic components of the heat dissipation effect is poor, resulting in the industrial tablet computer “crash”.
Solution: Clean the dust inside the industrial tablet computer regularly and keep good ventilation.
- Clean up temporary files frequently
When an industrial tablet is running, it creates a large number of temporary files, which take up hard disk and system resources and affect the speed of processing information on the industrial tablet.
Solution: Improve the processing speed of industrial tablets by checking hard drives regularly and deleting temporary files.
- Large amount of data leads to low CPU efficiency
When the industrial tablet computer processing through THE PLC transmission of the field signal is too much, the CPU efficiency of the industrial tablet computer is low, the memory is small, unable to identify and process so many signals at the same time, so that these signals “crash”, causing the industrial tablet computer “crash”.
Solution: Due to the limitations of the memory slot of the industrial tablet motherboard, the intelligent memory expansion to 64M. The main solution is to reduce the frequency of industrial tablet computer processing identification field signal, to avoid signal “crash”.
The specific scheme is: when the industrial tablet computer connects the field signal through 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 be more than 10s. In the programming process, when the sampling period of all analog signals is set above 2s, the “crash” phenomenon of industrial tablet computers rarely occurs.
- Check CPU fans and host power fans
The heat dissipation of industrial tablets is mainly carried out by CPU fans and power fans. When the CPU fan is damaged, the TEMPERATURE of the CPU increases, which can easily cause the “crash” of the industrial tablet computer.
Solution: Check fans on industrial tablets frequently and replace damaged fans in a timely manner. When the industrial tablet computer in the central control room leaves the factory, the CPU is only equipped with heat sink, no fan. After installing a special heat dissipation fan, the temperature of the CPU is reduced by nearly 5℃.
The above is the possibility of industrial tablet computer crash, in general, in addition to the correct operation, but also need to maintain the necessary, in the use of the process but also pay attention to the temperature, to often clean up temporary files, pay attention to these matters, can reduce the occurrence of industrial tablet computer “crash”.
There are two main reasons for the “crash” of everyday industrial tablets: board failure and system failure. As the most basic and core part of hardware and software, their application is critical. So this requires us to follow the precautions when we usually apply, and timely maintenance.
