Embodiment 1
[0042] figure 1 It is the overall design scheme of the electrostatic data acquisition system. The signal detected by the EST201 non-contact vacuum electrostatic detector passes through a 500-ohm resistance to generate a 5V voltage analog signal, and the analog signal enters the ICP DAS 7017 acquisition module connected to the DC power supply. The ICP DAS 7017 acquisition module converts digital signals and outputs RS-485 serial communication signals. The digital signals enter the computer MOXA CP-114 multi-serial board, and the dust electrostatic voltage value is read by the MCGS software system installed in the computer. , to achieve real-time monitoring of dust static electricity.

The invention relates to a dust static real-time monitoring method which mainly solves the problems that in the prior art, design is complex and cost is high. According to the dust static real-time monitoring method, signals detected by a static detector generates voltage analog signals through a resistor, the analog signals enter a collection module connected with a direct-current power source and are converted into digital signals through the collection module, RS-485 serial communication signals are output, the digital signals enter a computer multi-serial-port board card, an MCGS software system installed in a computer reads dust static voltage values, real-time monitoring on dust static is achieved, and the technical scheme can be applied to dust static real-time monitoring.
Description
technical field [0001] The invention relates to a real-time monitoring method for dust static electricity. technical background [0002] Industrial static electricity is the static electricity generated and accumulated on materials, devices, human bodies, equipment and buildings during industrial production, storage and transportation. It has a great impact on production safety and product quality. With the development of science and technology and the progress of human society, polymer materials, microelectronic devices and explosion-proof devices are widely used in various fields, and the harm caused by static electricity is increasingly concerned by people. Electrostatic discharge can not only cause combustion and explosion other than flammable and explosive gases, but also interfere with electronic equipment and cause accidents. For this reason, the study of electrostatic protection measures has become a research field that industrialized countries attach great importa...
