Abstract:In order to improve the real-time and stability of wireless data transmission, enhance the convenience of system maintenance and the flexibility of system transformation, a wireless communication-based tailing pond online safety monitoring system was designed based on the actual situation of Jinyin tailing pond. The seven online monitoring indicators and their corresponding plan layout of each monitoring point were determined. The hardware topology of the tailing pond online safety monitoring system and each monitoring subsystem was constructed based on wireless digital radio and wireless bridge. According to the control requirements of data acquisition, the hardware circuit of the collector was designed. Finally, the implementation flow of system data acquisition was given. This solution is simple, easy to implement and maintain, and has some significance for the efficient management of tailings ponds.
