摘要：In this paper, in order to meet the needs of monitoring engineering such as coal mines, oil fields, dams, bridges, shipbuilding, this paper design vibrating wire sensor signal acquisition board based on the STM32.
   The structure of the paper is as follow: To begin with this paper introduce the circuit and program design with STM32 as the core. By the analysis of isolation vibration frequency and vibration pickup circuit, this paper introduce an equal precision frequency measurement module based on STM32 and RS485 for long-distance communications, which is easy to cascade and extend.
   The systematic contrast experiment shows that the signal acquisition board has stable performance, high precision, and meets the requirements of actual measurement applications.
