Wireless strain data acquisition apparatus based on ZIGBEE

The utility model relates to a wireless strain data acquisition apparatus based on ZIGBEE. The wireless strain data acquisition apparatus comprises a strain acquisition module, a digital processing module and a wireless transceiving module, wherein the strain acquisition module consists of a strain bridge, a programmable analog signal adjuster and an AD converter; a voltage signal generated by deformation of a strain gauge is acquired through the strain bridge connected with the strain gauge, and then transmitted to the digital processing module after processed by the programmable analog signal adjuster and the AD converter; the digital processing module is provided with a core part processor, and the data processed by the processor is transmitted to the wireless transceiving module through a USART (Universal Synchronous Asynchronous Receiver Transmitter) interface; the wireless transceiving module is provided with a wireless transceiving chip; and the output end of the wireless transceiving chip is additionally provided with a power intensifying circuit, and the data processed by the wireless transceiving module is sent by an antenna end to an upper computer according to ZIGBEE protocol. The wireless strain data acquisition apparatus solves the problems of a strain transducer such as temperature drift and nonlinearity, and the like and can realize the communication within a distance of 300m in open areas.
