Abstract
Given the broad monitoring range and long monitoring time of anchor bolt loosening of draught fan, and harsh site environment in offshore wind power projects, a remote temperature and pressure monitoring system was designed in this study to realize the real-time wide-range monitoring of anchor bolt loosening of draught fans. The strain pressure transducer and platinum thermistor were used at the test end to acquire the pressure and temperature data, respectively. stm32f103 was used as the master controller in the acquisition system, hierarchical networking was conducted via Modbus protocol, and the long-distance transmission was realized by a fiber optical transceiver. LabVIEW was used by the upper computer to establish the client side to implement the data acquisition, storage and real-time monitoring.
