When the signal is input to the main control board of the MCU for processing, external interference will also enter through the input port. In addition to the use of anti-jamming device optocouplers on the input interface, anti-interference measures must be taken on the software to ensure reliable operation. Otherwise, it will cause a malfunction and make it not work properly. From the input port, the interference is a random spike with varying amplitude and width. The main task of anti-jamming design is to identify the authenticity information, discard the interference, and leave a useful signal. We have taken the following measures and received good results. The pulse width discrimination input pulse has a certain width, and the interference is mostly a sharp pulse, and continuous sampling is needed to distinguish the true signal from the interference signal. First, collect the signal and look for the rising edge of the signal. When the rising edge is found, it is sampled K times multiple times (four times in the figure), and if there is still a signal after K times, it is considered to be a true signal. If the signal is not collected after 2 to K times, it is considered that the interference signal is just collected. With this method, the intrusion of the interference signal can be greatly suppressed. (Finish) The air source processor is an element that does work through the force generated by the pressure or expansion of the gas, that is, a machine part that converts the elastic energy of compressed air into kinetic energy. Including air filter, pressure regulating valve, oil mist, etc. Start up products are widely used in automatic production of metallurgical Electromechanical, construction industry, transportation equipment, household appliances, light industry, machine tool, medical treatment, packaging industry and other industries. However, because the compressed air discharged by the air compressor cannot be directly used, the compressed air contains a certain amount of water, oil and dust. The compressed air temperature is up to about 140-170 ℃, and some water and oil have become gaseous. Therefore, the purified compressed air must be used to operate the mechanical equipment Air Source Processor,Air Source Treatment Pneumatic Filter,High Pressure Air Regulator,Air Filter Pressure Regulator Glove Industry Co.,Ltd. , https://www.glovemech.com
