First, the ambient humidity is not suitable.
Industrial computers are mainly composed of integrated circuits of many electronic components, and their insulation properties are closely related to the ambient humidity. Excessive humidity can easily lead to short circuits and incineration of the circuit board. If the humidity is too low, static electricity will easily occur, and some electronic components will be damaged, which requires a good instrument grounding on the industrial control computer. As a result, both high and low humidity can be a potential threat to industrial control computers.
Second, the sense of the ground should be stable.
In the automatic control system, the simple high-speed operation of the disk for a long time leads to the decline of the disk read and write ability, the slow positioning of the head, and even the damage of the disk due to oscillation. In engineering design, industrial control computers should be as far away as possible from the job site with large seismic sources. If the location cannot be changed, sponges and cushions can be placed under industrial control cabinets and boxes to reduce damage caused by oscillations.
Third, the temperature is not suitable.
If the chassis temperature reaches 30 degrees Celsius, the internal hard drive temperature will reach 40 degrees Celsius or higher. You can simply manipulate your industrial computer to lower the ambient temperature. First of all, 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 frame to prevent the hard disk from oscillating due to fan rotation, (1) to accelerate heat dissipation; (2) Install a fan inside the case to exhaust the air outside the case, thereby adding air convection; (3) A small axial fan is installed on the cabinet where the industrial computer is placed; (4) Equip the control room with air conditioning to reduce the temperature of the space.
Fourth, the power supply voltage fluctuates greatly, and the power supply failure simply occurs.
With the rapid development of industry and life, the demand for electricity is also increasing. In many areas, there is a lack of power supply, unstable voltages and simple power outages. Unstable voltage and sudden power failure lead to frequent system restarts, and system files are simply thrown away and cannot be started normally. Heads that perform read and write operations sometimes cause disk failures in industrial PCs due to the failure of the heads to come back. Therefore, the stability of the power supply in the working environment of the industrial control computer is related to the normal operation of the industrial control computer. Regulated power supplies and uninterruptible power supplies are available for protection. The specific choice of equipment depends on the load power and the operating time to be maintained.
5. There are many inhalable particles in the air.
Most of the raw materials in many factories need to be processed with powders. In addition, because of the flow of outside air and dust, a lot of sticky dust can easily accumulate in the industrial control computer, resulting in high local temperatures and hardware damage in the industrial control computer. This condition often occurs around cooling fans, such as CPUs, power supplies, hard drives, graphics cards, etc. For places with light dust accumulation, regular soot blowing can be selected under the condition of normal production. For places where dust accumulation is severe, a dust filter can be installed in the ventilation section of the industrial control cabinet and cleaned regularly.
