| Abstract: | This paper presents an ad hoc wireless dynamic strain acquisition circuit with high precision. The design selects TI＇s ZIGBEE solution to build ad hoc wireless network with constant current bridge to improve the anti-interference ability and the precision of sensor, builds up a driving circuit for the＇ADC, and has the circuit to be experimented. Experimental results show that the design has better environmental adaptability, maintainability and excellent precision, and can meet the distributed fatigue test of large and complex structures. |
