摘　　要：在复杂的煤矿井下环境中,现有的井下人员定位分站很难实现对井下人员精确、稳定的定位;研究了一种基于CAN总线通讯技术的增强型井下人员定位分站系统,以ARM7为核心控制芯片,结合ZigBee无线通讯技术,并对系统进行Matlab仿真和实验;仿真图像的对比显示增强型驱动CAN总线信号传输传输距离大于标准型CAN总线,传输时间减小了45%;在传输速率为30kbit/s时进行的实验结果表明,增强型的CAN节点幅值4.5V比标准CAN结点的2.1V提高了约1.2倍;仿真和实验的结果表明,增强型CAN总线定位分站信息传输时信号的传输距离增大、信号延迟减弱、幅值衰减明显减小。In a complex environment of coal mine, the existing mine substation positioning station is difficult to achieve accurate and sta- ble positioning of the underground staff. It studies an enhanced mine positioning station system based on CAN bus communication technolo gy, ARM7 as the core to control chip, combined with the ZigBee wireless communication technology, and Matlab simulation and experiment on the system. Comparison of simulation image displayed enhanced drive CAN bus signal transmission distance is greater than the standard- CAN bus, the transfer time reduces 45% ; Experiment results show that when the transmission rate is 30Kbit/s, enhanced CAN node value 4.5V is more than standard CAN node value 2.1V up to about 1.2 times. Simulation and experimental results show that： Enhanced positio ning CAN bus station enhanced signal transmission distance significantly, reduced signal delay, reduced the amplitude attenuation significant ly when transport information.
