After the long-term operation of the industrial tablet, there is a lot of dust in the chassis and the temperature of the chassis is high. At this time, it is very simple to cause the disk failure of the industrial tablet computer, the product quality problems of the hard disk itself and the failure problems caused by the working environment.
1. The relative humidity of the air is not suitable
The key to industrial tablet PCs is composed of integrated circuit chips with many electronic components, and their dielectric strength can be greatly related to the relative humidity of the air. It is very simple to cause short circuit damage to the circuit board due to excessive ambient humidity; Assuming that the ambient humidity is too low, it is very simple to form electrostatic induction, which will also penetrate some electronic components. Therefore, too much or too little ambient humidity can be a potential threat to industrial tablet PCs.
Solution: The problem of electrostatic induction safety protection stipulates that it is necessary to have excellent instruments and equipment grounding devices on your industrial tablet computer. Special attention should be paid to the electrical level of the grounding device on the industrial tablet PC is different from the lightning protection grounding wire in the construction profession. The electrical stage of the grounding device should be located at 3Km of the main control room and 1700mm below the field road.
Second, the internal temperature of the industrial tablet computer is too high
In the natural environment of long-term high-temperature operation, the components on the computer are very simple and brittle, and the frequency of computer hard disk defects is higher. This requires factory automation server protection staff to pay close attention to the temperature of the chassis during daily inspections, and to maintain the temperature on the industrial tablet at 10-30°C as much as possible. Temperatures that are too high or too low should not be protected by computer hard drives. Assuming the chassis temperature is 30°C, the internal computer hard drive temperature will be 40°C or higher.
Solution: We can easily and correctly guide everyone's industrial tablet PC to reduce the natural ambient temperature. The first is to disassemble and replace the high-power CPU and computer hard disk cooling fan (the computer hard disk cooling fan should be fixed, not installed on the computer hard disk fixture shelf, to prevent the computer hard disk from vibrating due to the rotation of the cooling fan), and speed up heat dissipation; The second is to install a cooling fan inside the chassis to pump gas to the outside of the chassis to enhance air convection. 3. Install a small and medium-sized axial fan on the server cabinet on the industrial tablet computer; Fourth, install air conditioning in the main control room to reduce the temperature of the indoor space.
Third, the industrial tablet computer has a long working time
Because it is necessary for all normal production and production, it is necessary for the industrial production automatic control system of some processing plants to work for a long time, which has caused a great tempering of the computer operating system on the industrial tablet computer. According to Microsoft's computer operating system operation time report, Microsoft claims that its computer operating system after Windows 2000 can be applied to long-term work, but from the perspective of the operation process, after the actual operation time exceeds a week, a lot of data information fragments will accumulate in the whole process of data transmission, which is very simple to form hard disk logic problems, incorrect reading and writing ability, and slow operation of system software.
Solution: Restart the industrial tablet PC when the production of the industrial tablet PC allows, unfold the disk defragmentation on time, and reduce the incorrect hard disk caused by long-term work. The restart time can be clarified depending on the amount of information processed on the industrial panel PC and the production status. It is necessary for the reader to explore gradually. According to the social experience of creators, rebooting an industrial tablet once a month (30 days) and tidying up can reduce the chance of hard disk mistakes.
