摘　　要：针对目前煤矿井下设备振动加速度信号获取困难的问题,研究了矿用本安型振动传感器的研制方法,选用内装集成电路放大器IC的振动加速度传感器,通过矿用阻燃电缆连接信号调理模块,由21 V本安电源为信号调理模块供电,设计信号调理板的本安供电调理模块,为振动加速度传感器供电,并实现振动信号的调理功能。该仪器在本安试验中测得的本安参数分别为:本安电压DC21 V,本安电流65 mA,本安电容和本安电感均为0。通过对标准振动信号(频率159.2 Hz)进行采集测试,结果表明,该矿用本安型振动传感器研制方案可行。According to the difficulty problem to get the vibration acceleration singles in present underground mine, the research and devel- opment method of the mine intrinsic safe mode vibration sensor was studied.The vibration acceleration sensor with the built-in integrated circuit amplifier IC was applied.With the mine fire resistance electric cable connected with the signal control module, a 21 V intrinsic safe electric power was applied to supply the power to the signal control module.The intrinsic safe power supply control module for the design of the signal control board was applied to supply the power for the vibration acceleration sensor and could have the control function of the vi- bration single.The intrinsic safe parameters measured by the instrument were the intrinsic voltage of DC21 V, the intrinsic current of 65 mA,the intrinsic capacitance and the intrinsic inductance is zero individually. The collection and measurement were conducted on the standard vibration signals （frequency 159.2 Hz）.The results showed that the research and development program of the mine intrinsic safe mode vibration sensor was feasible.
