Bridge intelligent sensing system based on Internet of Things

The invention provides a bridge intelligent sensing system based on the Internet of Things. The bridge intelligent sensing system comprises a data acquisition module, a data transmission module and a data monitoring module. The data acquisition module comprises a wireless sensor node and a data forwarding base station; the wireless sensor nodes are used for acquiring state data of the bridge; the data forwarding base station is used for sending the state data to the data transmission module, and is used for dividing the wireless sensor nodes into member nodes and cluster head nodes by adopting a self-adaptive clustering period; the data transmission module is used for transmitting the state data to the data monitoring module; and the data monitoring module is used for judging whether the state data is abnormal or not to obtain a judgment result. According to the invention, the energy consumption of the wireless sensor nodes is balanced, and the situation that part of the wireless sensor nodes quit work in adv
