The failure of the industrial computer is caused by external reasons

The temperature is not suitable for the maintenance of the hard drive, if the case temperature reaches 30 degrees Celsius, the temperature of the internal hard drive will reach 40 degrees or higher. We can briefly DIR our industrial computer to achieve the effect of reducing 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 speed up 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 failure of the industrial computer is caused by external reasons

1. The ambient humidity is not suitable

The industrial computer is mainly composed of integrated circuits of many electronic components, and its insulation function has a lot to do with the ambient humidity. If the humidity is too high, the circuit board will be short-circuited and incinerated by simply forming a short circuit; If the humidity is too low, static electricity will simply be generated, and some electronic components will be broken down. Therefore, too much humidity and too little humidity will bring potential threats to the industrial computer. The problem of electrostatic protection requires that we need to have a good instrument grounding on the industrial computer. It is worth clarifying that the grounding electrode of the industrial computer is different from the lightning protection grounding on the civil engineering, the grounding electrode site should be three meters away from the control room, and the ∮20 galvanized angle steel is used as the vertical direct ground electrode at 1700mm under the outdoor floor, and the number of grounding meets the grounding resistance of less than 1 ohm (the application of the shake meter test when backfilling), and then the selection of 40 * 40 * 4 galvanized flat steel and the grounding body are reliably welded (each welding point should be carefully treated with anti-rust), and the 25mm copper cable is transferred to the building to the system ground terminal and the industrial computer address. This can effectively reduce the damage caused by static electricity.

Second, the earthquake on the ground is large

In the production of many factories, the motor is required to produce physical bit movement actions such as drag and sensation, which not only brings huge noise, but also brings huge damage to the industrial computer disk, optical drive and floppy drive when the machine is operating. The process of producing disks is getting higher and higher, and the current speed has reached 7200 revolutions per second or even higher. In the large amount of data exchange 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 positioning of the head, and even disk damage; Therefore, it reduces the environmental vibration of the industrial computer and is conducive to the maintenance of the disk. When we are in the process of engineering design, we can keep the industrial computer away from the operation site with a large seismic source as much as possible; If the job address cannot be changed, we can also place sponges and bufferable objects under the industrial control cabinet and box to reduce the damage caused by the sensation.

3. 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 large amount of sticky dust is simply accumulated in the industrial computer, resulting in excessive 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 places where the dust accumulation is light, punctual dust blowing can be selected under the condition that normal production allows. In places where the dust accumulation is serious, dust filter gauze can be placed in the ventilation area of the industrial control chassis and sorted out regularly.

Fourth, the power supply voltage fluctuates greatly and is prone to power failure

With the rapid development of industry and daily life, the demand for electricity is also increasing, and many areas have insufficient power supply, unstable voltage, and easy power outages. The voltage is unstable and the sudden power failure causes the system to restart frequently, and the system files are also simple and therefore lost and cannot be started normally; The head that is performing the read and write action sometimes causes the head to return inaccurately due to power failure, which causes the disk problem of the industrial computer. 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. We can choose stabilized power supply and UPS uninterruptible power supply for maintenance, and the specific equipment selection should be determined according to the load power and the amount of operation time that needs to be maintained.
