Abstract： [Purposes] In response to the problems of high pier displacement in mountainous highway bridges caused by terrain，climate and other factors，as well as the high cost and poor environmental adaptability of traditional monitoring methods，a lightweight monitoring system and its supporting software platform were developed to enable eficient，real-time monitoring of high-pier displacement.[MethodslA lightweight monitoring system was built using miniaturized low-power tilt and displacement sensors，reliable wirelesstransmission technology，and a monitoring and warning software platform.Taking a bridge in a mountainous area of Guizhou as an engineering example，long-term on-site monitoring was carried out in the complex climate and environment of the mountainous area.[Findings] The monitoring system operated stably in the field environment and successfully captured the periodic deformation pattern of the high pier， which was dominated by temperature changes.A comparative analysis showed that the monitoring results were in close agreement with the finite element simulation results.[Conclusions] Through real-time monitoring and early warning，bridge safety hazards can be detected in a timely man

ner，significantly improving bridge operational safety，reducing maintenance costs，and thus possessing substantial engineering application value and economic benefits.
