Abstract

Taking long-term measurements on in-service bridges is challenging due to the lack of easy access to power and communications. Whilst all-in-one, portable sensor data loggers act to address these challenges, they still lack the flexibility to meet evolving measurement needs. This paper presents the design and implementation of a highly flexible, modular sensor system for bridge structural health monitoring research, which has an emphasis on customisability and extensibility to allow it to meet evolving challenges. The architecture incorporates interchangeable sensor modules that allows data acquisition to an on-board Secure Digital card, with timing and synchronisation provided by global positioning system and a real-time clock chip and remote system monitoring and control utilising LoRaWAN. A prototype system has been developed and tested in both laboratory and field trials.
