摘　　要：工程建设领域建构筑物沉降自动化监测需要实现高精度、广覆盖范围和稳定通讯。为解决上述问题,以容栅静力水准仪为采集设备,设计了一套静力水准沉降自动化监测系统。系统运用基于低功耗广域网(LPWAN)无线通讯技术,实现广覆盖、低成本和高稳定性的沉降数据采集和远程传输。对系统进行试验测试表明,在城市环境中系统的稳定覆盖范围不小于2.5 km,数据采集精度可达±0.15%。实际工程应用测试表明,自动化系统沉降监测结果与同期人工测量结果基本一致,满足工程中可覆盖范围广、数据稳定性高、通讯成本低的沉降自动化监测的要求,具有一定的应用意义。The automatic monitoring of settlement of structures in the field of engineering construction requires high accuracy,wide coverage and stable communication.In order to solve the above problems,designs a set of static level settlement automation monitoring system with capacitive grid static level as the collection device.The system utilizes wireless communication technology based on low power wide area network(LPWAN)to realize wide-coverage,low-cost and high-stability settlement data acquisition and remote transmission.Experimental tests of the system show that the stable coverage range of the system is not less than 2.5 km in an urban environment,and the accuracy of data collection can reach±0.15%.The actual engineering application tests show that the results of the automated system settlement monitoring are basically consistent with the results of manual measurements in the same period,which meets the requirements of the automated settlement monitoring with wide coverage,high data stability,high accuracy and low cost in the project,and has certain application significance.
