摘　　要：为了检测煤矿巷道支护体受力状况,介绍了一种矿用锚杆静态电阻应变仪。该应变仪采用ATMega16L作为主控芯片,包括硬件电路及软件部分的设计,硬件上采用电子程控开关切换、精密仪表放大器和先进低频滤波等对信号采集调理,并采用LCD汉字显示检测结果;软件上下位机利用AVR单片机的输入捕捉、CTC模式、I2C等功能。实验结果表明:矿用锚杆静态电阻应变仪精度高、电路简单、汉字显示,具有较高的抗干扰能力;在测量煤矿巷道支护构件(锚杆、锚索)所受应力大小的工作中,给井巷锚固工作带来了更便携的测试手段。In order to monitor the stress of bolt support in coal mines,a static resistance strain gauge for mine roof bolt is presented in this paper.The static resistance strain gauge is developed based on ATMega16L including hardware and software design.The electronic program-controlled switching technology,precision instrumentation amplifier and advanced low-frequency filtering are integrated in hardware design for signal collection.LCD is selected for displaying the results in Chinese.The input capture function,CTC and I2C of AVR16 are applied in programmable logic controller.The experimental results demonstrate that the strain gauge has high precision,simple electric circuit and Chinese display.As a secondary instrument for measuring the stress of support structures（including rock bolt and anchor rope）,it provides a more portable testing method for personnel who undertake anchoring works in coal mines.
