Abstract: In order to solve the problems of low efficiency and poor security of college English education resource sharing, a resource sharing system of college English education based on wireless sensor network is proposed. The overall function of the resource sharing system is designed. In the hardware design of the system, the hardware of the wireless sensor node is designed. The model of PIC18LF6680 microprocessor is selected, and the standard RS232 serial port is extended to MAX232 level converter. Digital sensors are designed to realise the high-speed transmission of shared resources. On this basis, the hierarchical structure of the system is designed. In the software part, Kalman filter is used to detect noise and measure noise. According to different network conditions, the delay of wireless network system is controlled. The results show that the maximum sharing efficiency of the system is 98%, and the energy consumption of the system is low.
