Abstract:To realize the monitoring of the slope stress, ensure the safety of strip mine production, based on the theory of vibration string sensor research and analysis, this paper developed a model for its the core of the slope wireless remote monitoring system. First, it describes the vibration string sensor principle, then to points node stress acquisition and data transmission part of the hardware, the key technology of frequency measurement and software design, and finally put forward part Measurement cycle method frequency experiment measured. The practical application showed that in the slope sensor vibration string application of wireless remote monitoring system with induction sensitive, hardware circuit reliable, excitation efficient, price cheap, fast detection feature, and the mining related product development is of important value, have broad application prospects.
