摘要：In the working state detection of mechanical system, the strain monitoring of moving object is of great significance. In order to break through the limitation of applicable occasions for the static strain gauge and cable transmission of information, this paper introduces the design of a multi-channel wireless monitoring device which is based on the principle of small volume and convenient carrying, describes the design principle of signal acquisition, processing, transmission and display device. Combined with the actual demand, the power supply of the device is selected and the corresponding circuit is designed. At the same time, the amplification circuit is simulated to verify its feasibility and reliability. Finally, the error analysis of the whole device is made and the corresponding solution is tried to make the device have higher practical value. ? 2019 IOP Publishing Ltd. All rights reserved.
