Research of Wireless Sensor Network Node Based on Vibrating Wire Sensor of Single Coil and Phototube
The merits of conventional vibrating wire sensor(VWS) used for roof pressure monitoring are introduced, based on photoelectric single coil VWS and ZigBee technique, this paper has designed a wireless sensor network node. In the mean time, this paper has designed the circuits of wireless communication module、the software design approaches of sweeping frequency and networking for wireless sensor network nodes. Compared to traditional vibrating wire sensor used in roof pressure monitoring system, which not only solves the electromagnetic interfere problem in the course of frequencies’ excitation and picking up but also avoids the difficulty when setting up equipments and laying wires.
