The ambient humidity is not suitable. The industrial computer is mainly composed of integrated circuits of many electronic components, and its insulation function is greatly related to the ambient humidity. If the humidity is too high, it is easy to form a short circuit and burn the circuit board; If the humidity is too small, it is easy to generate static electricity, and it will also break down some electronic components, so it is required that there must be a good instrument grounding on the industrial computer. Therefore, too much humidity and too little humidity will bring potential threats to the industrial computer.
The ground tremors were felt greatly. In the automatic control system, the disk that runs for a long time and at high speed is prone to disk sensation, resulting in disk read/write ability decline, 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 work location cannot be changed, sponges and bufferable objects can also be placed under the industrial control cabinet and box to reduce the damage 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 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 from causing a sensation due to 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. On the cabinet where the industrial computer is placed, a small axial fan is installed; 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 days, the demand for electricity is also increasing, and many areas have insufficient power supply, unstable voltage, and easy power outages. Voltage instability and sudden power failure cause the system to restart frequently, and the system files are also easy to lose and fail to start normally; The head that is performing the reading and writing operation will sometimes cause the disk problem of the industrial computer due to the inaccurate return of the head due to power failure. 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 choose stabilized power supply and UPS uninterruptible power supply for protection, and the specific equipment selection should be determined according to the load power and the amount of operation time that needs to be maintained.
There is a lot of inhalable particulate matter in the air. In many factories, most of the materials need powder for processing, coupled with large external air activity and dust, it is easy to accumulate a large amount of sticky dust in the industrial computer, resulting in excessive local temperature in the industrial computer and causing 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, punctual dust blowing can be selected under the condition that normal production allows. In the local area where the dust accumulation is more serious, the dust filter gauze can be placed in the ventilation place of the industrial control chassis and sorted out regularly.

The difference between industrial computer hard disk - EVOC
1. Hard disk speed
The speed of the hard disk is one of the important parameters to identify the level of the hard disk, and it is one of the key factors of the internal transfer rate of the hard disk, which directly affects the speed of the hard disk to a large extent. The speed of the hard disk refers to the rotation speed of the motor shaft in the hard disk, which is the speed of the hard disk in 60 seconds.
