After the industrial tablet PC has been operating for a long time, a lot of dust has accumulated in the chassis and the chassis temperature is high. At this time, it is easier to cause disk failures. These reasons are divided into disk quality problems and working environment failures. How to solve this kind of problem?
1. Long working hours for industrial tablet computers
Because of the needs of normal production, the industrial control system of some factories needs to work for a long time, which brings a huge test to the industrial tablet computer operating system. According to Microsoft's operating system runtime report, Microsoft claims that its operating system after Windows 2000 can support long-term work, but from the actual operation, after operating for more than a week, the disk will accumulate a lot of data fragments during the huge data exchange process , It is easy to cause disk logical bad sectors, read and write errors, and slow system operation and startup.
Solution: The industrial tablet can restart the industrial tablet and defragment the disk regularly when production permits to reduce disk errors caused by long-term work. The restart time can be determined according to the amount of data processed by the industrial tablet and the production situation. It is not rigid and requires readers to explore slowly. From the author's actual experience, restarting and organizing an industrial tablet once a standard month (30 days) can reduce the probability of disk errors.
2. The internal temperature of the industrial tablet is too high
In an environment that requires long-term high-temperature operation, the components of the computer are prone to aging, and the frequency of hard disk failures is also increased. This requires that the factory's automation system maintenance personnel pay close attention to the temperature of the chassis during daily inspections, and try to keep the temperature of the industrial tablet between 10--30 degrees Celsius. Excessively high and low temperatures are not suitable for hard disk protection. If the chassis temperature reaches 30 degrees Celsius, the internal hard drive temperature will reach 40 degrees or higher.
Solution: We can simply DIR our industrial tablet to reduce the ambient temperature. 1. Replace the high-power CPU and hard disk fan (the hard disk fan should be fixed and should not be installed on the hard disk firmware rack to prevent the hard disk vibration caused by the fan rotation) to speed up the heat dissipation; , To increase air convection; three, install a small axial fan on the cabinet where the industrial tablet computer is placed; fourth, install air conditioning in the control room to reduce the space temperature.
3. The environment humidity is not suitable
The key of the industrial panel computer is composed of integrated circuits of many electronic components, and its insulation performance has a great relationship with the environmental humidity. If the humidity is too high, it is easy to cause the circuit board to be short-circuited and burned; if the humidity is too low, it is easy to generate static electricity and it will also breakdown some electronic components. Therefore, if the humidity is too high or too low, it will bring a potential threat to the industrial tablet.
Solution: The problem of electrostatic protection requires that our industrial tablet computers must have a good instrument ground. It is worth noting that the grounding pole of the industrial tablet computer is different from the lightning protection grounding on civil engineering. The location of the grounding pole should be three meters away from the control room and 1700mm under the outdoor floor.
