What are the common factors resulting in failure of industrial control machine?

Industrial computer is also known as industrial control computer, industrial control computers with important attributes and characteristics, such as a computer CPU, hard disk, memory, peripherals and interface, and the operating system, control network and protocol, industrial control computers with important attributes and characteristics, and the operating system, control network and protocol, computing power, friendly man-machine interface, computing power, friendly man-machine interface. Industrial PC using the same over time, in time, the environment, under the influence of factors such as voltage will fail, below small make up is the external cause of industrial computer fault do some simple analysis: more than one, the particulate matter in the air: most of the plant material need powder processing, and large outside air flow and a lot of dust, industrial PC within easy to accumulate a large amount of sticky dust, local high temperature caused by industrial PC, hardware damage. This kind of situation happens in CPU, power supply, hard disk, video card, such as a cooling fan around. Dust is lighter, in normal production permission, can use time * * *. Can place with severe dust, industrial PC box placed drafty place strainer gauze, regular cleaning needs to be done. Second, the power supply voltage fluctuation, easy to power outages, now the development of industry and improvement of living standards, the demand for electricity is growing, some of the more remote areas prone to the phenomenon of the power supply insufficient, voltage instability. In industrial control system restart, frequent important log file system easy to lose and cause can't normal boot. Therefore industrial work environment, the stability of the power supply is related to industrial computer working properly or not. Need to adopt the regulated power supply and UPS uninterruptible power supply, equipment selection, in accordance with the size of the load power, how much need to keep working time. Three, environment humidity is not suitable for: industrial computer is made up of many electronic components integrated circuit, its insulation performance has a great relationship with environment humidity. Humidity, circuit board is easy to cause short circuit and burned; Humidity is too small, easy to generate static electricity, also can breakdown of electronic components. Therefore, humidity is too big, too small, will bring industrial potential threat. Electrostatic protection issues on the industrial PC we must be good instrument grounding. Four, the ground was shaking: many factories need motor drag, such as vibration displacement of physical movement, not only bring huge noise, the vibration of the machine is working to bring bring industrial computer disks, cd-rom, floppy drive huge damage. Disk production process more and more high. In automatic control system of a large number of data exchange, long operating time, high speed disk, easy for disk vibration, resulting in a decline in disk, speaking, reading and writing, head positioning is slow, and even damaged disk; Therefore reduce the aftershock, industrial environment is conducive to protect the disk.
