摘　　要：为满足文化遗产地的微振动环境监测需求,设计了可远程自校准的分布式组网无线微振动测试仪。通过测试仪硬件电路、固件程序、封装结构的合理设计,以及测试仪的校准试验和在敦煌莫高窟的现场试验,验证了设计的无线微振动测试仪具有无线分布式组网、集成度高、远程自校准、同步采样、自动定位、灵敏度高等特点,能够满足世界文化遗产地对微振动环境的长期大范围监测需求。该测试仪已经在敦煌莫高窟的风险预警系统中使用。In order to realize real-time micro vibration monitoring in the area of cultural heritage, a distributed wireless micro vibration testing instrument was designed with remote self-calibrate function. Through the rational design of hardware circuit, firmware program and package structure, at the same time the calibration experiment and field experiment in Mogao Grottoes of the testing instrument were implemented. It has been proved that the designed testing nstrument has the advantage such as distributed wireless networking, high integrated sense and adaptation, remote self-calibration ,synchronous sampling, automatic positioning and high sensitivity, which is able to meet the demand of micro vibration monitoring for long time and wide range in the area of world cultural heritage. At present the testing instruments are used in the risk early warning system of Dunhuang Mogao Grottoes.
