Due to the influence of external factors in the use of the industrial computer, it is very simple to have this or that failure, and if you do not understand the cause of the failure, it will form improper use, and also simply form the service life of some parts of the industrial computer. The external factors that affect the normal operation of the industrial computer are mainly as follows:
The ambient humidity is not suitable. Industrial computers are mainly composed of integrated circuits of many electronic components, and their insulation properties have a lot to do with ambient humidity. If the humidity is too high, the circuit board will be burned out due to a short circuit; If the humidity is too small, static electricity will be generated simply, and some electronic components will also break down, which requires an excellent surface grounding on the industrial computer. Therefore, too much humidity and too little humidity will bring potential threats to the industrial computer.
The tremor was felt on the ground. In the automatic control system, the disk that runs for a long time and at high speed is simply caused by the disk sensation, which leads to the decline of disk read and write ability, slow head positioning, and even disk damage. In the engineering design, keep the industrial computer away from the operation site with a large epicenter as much as possible; If the job address cannot be changed, sponges and bufferable objects can also be placed under the industrial control cabinet and box to reduce the harm caused by the sensation.
The temperature is not suitable. If the chassis temperature reaches 30 degrees Celsius, the temperature of the internal hard drive will reach 40 degrees Celsius or higher. You can simply DIR your own industrial computer to achieve the effect of lowering the ambient temperature. 1. Replace high-power CPU and hard disk fans (hard disk fans should be fixed and should not be installed on the hard disk firmware rack to prevent hard disk sensation caused by fan rolling) to accelerate heat dissipation; 2. Install an electric fan inside the chassis to exhaust air to the outside of the chassis and add air convection; 3. Install a small axial fan on the cabinet where the industrial computer is placed; 4. Install air conditioning in the control room to reduce the temperature of the space.
The power supply voltage fluctuates greatly and is prone to power outages. With the rapid development of industry and daily life, the demand for electricity is also increasing, and there is a lack of power supply, unstable voltage, and easy power outages in many areas. Voltage instability and sudden power failure, the formation of frequent restart of the system, the system file is also simple and therefore lost and cannot be started normally; The head that is performing the read and write operation sometimes causes the disk failure of the IPC due to the power failure of the head return. Therefore, the stability of the power supply in the working environment of the industrial computer is related to the normal operation of the industrial computer. It can use stabilized power supply and UPS uninterruptible power supply for maintenance, and the specific equipment selection should be determined according to the size of the load power and the amount of operation time that needs to be adhered to.
There is a lot of inhalable particulate matter in the air. Most of the materials in many factories require powder for processing, coupled with large external air activity and a lot of sand and dust, a lot of sticky dust is simply accumulated in the industrial computer, resulting in excessive local temperature in the industrial computer and hardware damage. This situation mostly occurs around cooling fans such as CPUs, power supplies, hard disks, and graphics cards. In the local area where the dust accumulation is light, under the condition of normal production, regular dust blowing can be used. In the local area where the dust accumulation is more severe, the dust filter gauze can be installed in the ventilation area of the industrial control chassis and sorted out regularly.

The shortcomings of EVOC's traditional PICMG PIC/ISA bus gold finger connection method
1. With the improvement of hardware channel functions, the power consumption also increases. The weight of the heat dissipation system fixed on the CPU card will inevitably increase, resulting in an unstable center of gravity of the CPU card, which is easy to cause problems such as deformation, wire breakage, and poor touch of the CPU card, resulting in unstable work.
