Control system anti-jamming measures

1. Suppression of power interference. Protection is generally achieved by setting up shielded cables and PLC local shielding and high voltage release elements. The selection of equipment with good isolation performance, the selection of excellent power supply, power line and signal line routing should be more reasonable, etc., the main components of the power transformer, the central processor, the programmer, the use of conductive and magnetomagnetic good materials for shielding processing to prevent the influence of external interference signals. Power adjustment and protection: Power supply fluctuations cause voltage distortion or spikes, which will have an adverse effect on the PLC and I/O module. The +5V power supply required by the microprocessor core components is processed by multistage filtering and adjusted by integrated voltage regulator to adapt to the fluctuations of AC power grid and the influence of overvoltage and undervoltage. When the power line is parallel as far as possible, the power line is low impedance to the ground to reduce power noise interference. The shielding layer grounding method is different, the interference suppression effect is not the same, the general secondary coil can not be grounded. The input and output lines should be twisted pairs, and the shielding layer should be grounded reliably to suppress co-mode interference. In addition, a 1:1 isolation transformer with a shielding layer can be installed to reduce the interference between the equipment and the ground, and LC filter circuits can be connected in series at the power input end.

2. Anti-interference measures introduced by signal cables. Power line, control line and PLC power line and I/O line should be distributed separately, the isolation transformer and PLC and I/O should be connected by twisted pair. The PLC I/O line and the high-power line are separated, such as must be in the same line slot, separate the AC line, DC line, if conditions permit, the best slot line, which can not only make it have as large a space distance as possible, and can reduce interference to a minimum. In addition, the use of signal isolator to solve the interference problem is also a very ideal way, the principle is to first PLC received signal, through the semiconductor device modulation transformation, and then through the light or magnetic sensing device isolation conversion, and then demodulation transformation back to separate the original signal or different signals, while isolating the power supply of the isolated signal. Ensure the absolute independence of the transformed signal, power supply and ground. As long as there is interference in the place, the input and output terminals between the isolator can effectively solve the interference problem.

3. Select the ground point correctly and improve the grounding system. Good grounding is an important condition to ensure the reliable operation of PLC, which can avoid the harm of accidental voltage shock. The purpose of grounding is usually two, one is for safety, and the other is to suppress interference. Perfect grounding system is one of the important measures for PLC control system to resist electromagnetic interference.
