Aiming at the problem that the frequency difference protection ability of the current intermittent pumping self optimization control system for low production wells is poor, which leads to large reactive power compensation error and long control time, a low production well intermittent pumping self optimization control system based on Internet of things technology is designed. According to the gas separation path, the control hardware component operation path is constructed. The dczl23-wfet600s-i collector is used to collect the internal information. The serial port connection mode of RS-485 is used to construct the information serial port connection mode. The data controller is used to standardize the control data to complete the control system hardware design. Match the control criteria and control platform program, query the best matching value information, complete the platform initialization processing, design the software control backplane, connect the control front end and control channel, construct the data transmission contact channel, use the photoelectric conversion isolation technology, exchange the sensing information of crude oil data, adjust the algorithm input mode, connect the central control network of the system software platform, and execute network connection command, control system software operation. The experimental results show that the overall value of the frequency difference protection is 7.0hz, the action value is 50.05hz, and the control time is only 7.6s. The frequency difference protection ability is good, which can effectively reduce the reactive power compensation error and shorten the control time.
