[Abstract]:The proportion of bridges in highland mountainous areas is relatively high. However various reasons lead to defects and diseases of bridges in addition to the complex terrain and backward communication it is impossible to monitor the health status of the bridges in real time and effectively.Therefore, it is urgent to carry out monitoring and early warning through advanced technology, carry out preventive maintenance in advance, and ensure the safety of people's life and property.In view of this, this paper analyzes and combs the diseases affecting the health of bridges and their causes, which has some reference significance for bridge monitoring and maintenance.In addition, this paper analyzes and designs the Beidou / GPS bridge health monitoring system based on low power consumption. The system makes use of the advantages of satellite monitoring means to effectively solve the lack of coverage of wired communication network in highland mountain areas.The problem of lack of professional and technical personnel can realize dynamic monitoring and safety evaluation of active bridges in highland mountain areas.At present, the system has been implemented and applied in Yunnan Province, which not only has the advantages of low cost and high efficiency, but also can realize real-time dynamic monitoring, which is very suitable for popularization and application in highland and mountainous areas.
