Several major factors affecting the stable operation of industrial control computers - Dongfang Song

  & nbsp; Industrial control computers are mainly used in areas where computers are needed in industrial automation systems. Generally, they require strong anti-interference ability and high reliability. During the working process, industrial control computers must ensure that all network cables and network configurations are normal, and there are corresponding standards for both network printing and regular operations. It is best for operators to train in operating skills before taking up their positions< br />
  & nbsp;& nbsp; Today, Dongfang Songbai Technology will analyze several reasons that affect the stability of industrial control computers< br />
  & nbsp;& nbsp; Reason 1: Dust on small components
  & nbsp;& nbsp; At present, the components and wiring used in industrial control motherboards are very precise. When dust accumulates too much in small components, it will absorb moisture in the air. Conductivity may connect different signals on small components or short-circuit resistors and capacitors, causing signal transmission errors or changes in working points, resulting in unstable operation or inability to start the industrial control computer.
  & nbsp;& nbsp; Reason 2: Dust on the motherboard
  & nbsp;& nbsp; In the practical application of industrial control computers, the control host often crashes, restarts, and cannot find the keyboard and mouse to activate alarms. This is mostly caused by the accumulation of dust on the industrial motherboard, which cannot be removed from the chassis. Dust is also a key factor affecting the service life of industrial control computers. Therefore, the dust and waterproof work of industrial control computers is very important.

  & nbsp;& nbsp; Reason 3: Poor working environment
  & nbsp;& nbsp; The power supplies used for industrial computer CPUs, memory, etc. are capacitors of varying sizes. Capacitors are afraid of high temperatures, which can easily cause capacitor breakdown and affect normal use. In many cases, the electrolytic capacitor on the main board will bubble or leak, and the capacitance is not caused by product quality, but because the working environment of the industrial main board is too poor.
  & nbsp;& nbsp; Reason 4: High temperature baking
  & nbsp;& nbsp; Usually, most of the bubbling, leaking and insufficient capacity capacitors appear around the CPU, the edge of the memory module and next to the AGP slot. Because these components are very hot, the generator in the computer. In long-term high-temperature baking, the above faults may occur to Aluminium electrolytic capacitor< br />
  & nbsp;& nbsp; If the environmental humidity in the space is relatively high, some dehumidification equipment can be used to reduce the humidity
  & nbsp;& nbsp; If the temperature of the space is too high, use air conditioning or electric fans to cool the external unit, and also ensure that the internal cooling holes of the computer are unobstructed and not blocked.
  & nbsp;& nbsp; If there is significant vibration in the space, it is recommended to place a layer of shockproof insulation material at the bottom of the industrial computer< br />
 
  & nbsp;& nbsp; Shourui Warm Reminder: When purchasing an industrial computer, you should choose a well ventilated chassis and regularly open the chassis to remove dust. Generally speaking, dust on the motherboard can be gently brushed off with a brush. However, due to the pin form of some cards and chips on the industrial motherboard, it is easy to oxidize and cause poor contact. You can use an eraser to remove the surface oxide layer and reinsert it. If conditions permit, trichloroethane with good volatile energy can be used to clean the motherboard.
