Abstract
Through the detection of bridge deck vibration, the information of passing vehicles can be obtained indirectly, so as to grasp the dynamics of the enemy. In this paper, a micro-power wireless vibration detection terminal is designed. In order to reduce power consumption, the terminal uses two sensors, one is the spring switch, the other is the acceleration sensor. When no vehicle passes by, the terminal is in a dormant state. As the vehicle passes by, the spring switch wakes up the CPU and the acceleration sensor to collect data. ZigBee network for data transmission has the advantages of low power consumption and ad hoc network. Experiments show that the average power consumption of the terminal is less than 7 mw. In theory, if the terminal is powered by 3.6V, 36Ah lithium batteries, it can work for at least two years.
