The cables used by our company for civil engineering safety monitoring instruments often break when used on the construction site. The use method of the instrument is to slide the free muffler of the instrument into each monitoring point (the pulley slides into the instrument in the pipe groove) with the aid of cable. The weight of the instrument, the weight of the cable and the resultant force of friction with the instrument are all borne by the cable. The circuit breaker of the circuit breaker is located at the connection between the instrument and the cable and other parts of the cable. The system can monitor the deformation, stress-strain and temperature of dam, bridge and high-rise building for a long-term on-line intelligent monitoring, and can automatically collect the data of vibration sensors for automatic analysis and prediction of measured values. It can be used for long-term on-line monitoring of deformation, stress-strain and temperature of dams, bridges, high mufflers and so on. It is mainly composed of optical fiber sensor, optical fiber and data acquisition instrument. Required technology: optical fiber sensor technology, optical fiber technology, data acquisition technology, etc. Our factory already has the foundation of CAN bus, and we need to study the high level can bus system and develop the test prototype. The key technical problems must be solved centrally.
