1. Poor internal heat dissipation of industrial tablet computers
Industrial tablet PCs are in a harsh environment, with a lot of dust in addition to high temperatures. When the dust enters the industrial tablet computer, the heat dissipation effect of various electronic components such as boards and CPUs is poor, forming the "crash" of the industrial tablet computer.
Regularly clean up the dust inside the industrial tablet and insist on good ventilation.
2. Frequently sort out the documents that are temporarily generated
When an industrial tablet is running, it generates a large number of temporary files, which occupy hard disk and system resources, affecting the speed at which the industrial tablet can process information.
Regularly check your hard drive and delete temporary files to improve the speed at which your industrial tablet can process information.
3. The amount of data is too large and the CPU power is low
When the industrial tablet computer processes too many field signals transmitted by the PLC, the CPU power of the industrial tablet computer is low, and the memory is small, so it is impossible to identify and process so many signals at the same time, which makes these signals "crash" and form a "crash" of the industrial tablet computer.
Due to the limitation of the memory module slot of the industrial tablet motherboard, the memory can be expanded to 64M. The main processing method is to reduce the frequency of the industrial tablet computer processing to identify the on-site signal and avoid the signal "crash".
The specific scheme is as follows: when the industrial tablet 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 such as temperature that does not change much can be set to more than 10s. In the programming process, after setting the sampling period of all analog signals to more than 2s, the "crash" phenomenon of industrial tablet PC rarely occurs.
4. Check the CPU fan and the host power fan
The heat dissipation of industrial panel PCs is mainly carried out through CPU fans and power fans. When the CPU fan is damaged, the temperature of the CPU rises, and it is very simple to form an industrial tablet "crash".
Always check the fan of the industrial tablet PC and replace the damaged fan in time. When the industrial tablet computer in the central control room left the factory, the CPU was only equipped with a heat sink, and there was no fan, and a special heat dissipation fan was installed later, and the temperature of the CPU dropped by nearly 5°C.
The above is the possibility of the crash of the industrial tablet computer, in summary, in addition to the correct operation, but also need the necessary protection and maintenance, in the process of use should also pay attention to the temperature, to often sort out temporary documents, pay attention to these matters, can reduce the industrial tablet "crash" situation.
There are two main reasons for the "crash" of everyday industrial tablet PCs, board failure and system failure, as the most fundamental and central part of hardware and software, their use is crucial. Therefore, this requires us to follow the precautions and repair and maintain them in a timely manner.
