1. Плохое внутреннее тепловыделение промышленных планшетных компьютеров.
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".
2. Чаще очищайте временные файлы
Когда промышленный планшетный компьютер работает, он создает большое количество временных файлов. Эти файлы занимают жесткий диск и системные ресурсы и влияют на скорость обработки информации промышленным планшетным компьютером.
Регулярно проверяйте жесткий диск и удаляйте временные файлы, чтобы повысить скорость работы промышленного планшетного компьютера.
3. Объем данных слишком велик, а эффективность ЦП низкая.
When the industrial panel computer processes too many field signals transmitted by the 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". ".
Due to the limitation of the memory slot of the industrial panel computer motherboard, the memory is intelligently expanded 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.
4. Проверьте вентилятор процессора и вентилятор блока питания хоста.
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".
Часто проверяйте вентилятор промышленного панельного компьютера и вовремя заменяйте поврежденный вентилятор. Когда промышленный панельный компьютер в центральной диспетчерской покидает завод, в ЦП устанавливается только радиатор без вентилятора, а позже устанавливается специальный охлаждающий вентилятор, и температура ЦП снижается почти на 5 градусов.
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. 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.
There are two main related reasons for the "crash" of daily industrial tablet computers. Board failures and system failures are the most basic and core parts of hardware and software, and their applications are crucial. So this requires us to follow the precautions and repair and maintain in time when we usually apply.
