摘　　要：介绍一种锚杆测力系统的测量原理及其系统的设计,测量原理以电阻应变片构成的全桥差分电路为基础,当锚杆受力时,桥式电路产生电压差变化,根据电压差对外部受力进行分析和测量。该设计以MSP430F425芯片为核心,以nRF905芯片作为无线收发模块,具有无线接收数据、LCD显示、报警等功能。该设计主要适用于煤矿巷道中锚杆应力状态的测量。Designing a system of bolt force measuring system and introduces the measuring principle.The measuring principle is based on the full bridge differential circuit. When the force acting on the bolt, the bridge circuit generates a voltage change according to the external force. Use the MSP430F425 as the core,and nRF905 chip as the wireless transceiver module. In the system there is also the LCD display, alarm and other functions. It＇s mainly used to measure the stress state of rock bolt in coal mine roadway.
