What are the influencing factors of intelligent factories for automatic devices?

Smart factory is to use various modern technologies to realize the office, management and production automation of the factory, to strengthen and standardize enterprise management, reduce work mistakes, plug various loopholes, improve work efficiency, carry out safe production, provide decision-making reference, and strengthen the external environment. The purpose of contacting and expanding the international market.

1. Electromagnetic radiation interference: When electronic control devices are used in factories, electromagnetic waves outside the equipment will be absorbed to form a kind of electromagnetic radiation. In addition, the temperature of electric shock appliances will gradually rise during high-frequency operation, and arcs and sparks will also follow. Generated, radiated electromagnetic waves will become a parallel product of electronic automation control devices. It should be noted that electromagnetic waves will interfere with the normal operation of automation devices. According to relevant investigations, the degree of interference to electronic automation devices varies with the intensity of electromagnetic waves. The higher the intensity of the electromagnetic wave, the greater its impact will be.

2. Co-group anti-interference There are many circuits inside the electronic automatic control device, as the medium connecting different circuit loops: the wire has an important impact on the operation of the electronic control device. In the wires of the electronic control device in operation, the current and voltage values generated are different, and the loop current in the electronic control device under this operation will be affected, forming a common group anti-interference, and the length and cross-section of the interference circuit will be changed. It has an impact on electronic devices. When the circuit forming the current in the line is long, and at the same time, when the cross-sectional area of the wire is relatively small, the anti-interference of the group will also affect the operation of electronic automation equipment.

3. Static interference: It is one of the most common interference factors affecting the operation of electronic automatic control devices. Static electricity can be transmitted to capacitors or capacitive couplers through the accessories contained in electronic automation itself, which will interfere with electronic automatic devices and affect their normal operation. run. When a strong current enters the device through the power line, the electric field strength of the device will increase. At this time, the power line and capacitor may be disturbed by static electricity, and its operation will face problems. If the length of the wire in the electric field is continuously increased, the power line and the disturbed The distance between the lines will be pulled apart, so that the power line and the wire are in a parallel direction and continue to extend, and its anti-interference ability will be effectively improved.

4. Leakage coupling interference: If the internal components of the electronic automation control device fail, or the electrical insulation between components is affected by the outside world, it will cause leakage of components, and leakage coupling interference will follow. For example, if the electronic automation device has been in a factory with humid air for a long time, due to the long-term heat generation of the internal working software, it will form water vapor when it encounters water vapor in the air. After a long time, the internal or external circuits of the components will age, and their insulation resistance There will also be a decline, which is often the case in factories with poor working conditions.

5. Power grid interference factors: Electronic automation devices must be charged if they want to run. The AC power of the grid used in the operation process will have a certain impact on the equipment during the conversion process, and then the computer will appear interference signals. At the same time, the computer The signal is coupled and processed through the transformer to form a high-frequency interference, which is parasitic in the capacitor for a long time and hinders the operation of electronic automation equipment.

6. Magnetic field coupling interference: The equipment contains a strong current, which may generate an induced magnetic field. This magnetic field will affect the equipment to varying degrees, and may damage electronic automation control equipment. Due to the impact of this magnetic field on electromagnetic equipment Relatively large, when the device is in daily work, the current will be affected by the magnetic field, which will cause strong interference to the daily operation of the equipment. In addition, other different magnetic fields will relatively control the stability of the current, making it subject to strong interference and affecting the daily operation of electronic automation devices.
