所述数码电子雷管包括第二二总线通信串口模块、检测模块和点火头，所述第二二总线通信串口模块分别与检测模块和第一二总线通信串口模块连接，通过第一二总线通信串口模块和第二二总线通信串口模块实现手持设备终端控制模块与数码电子雷管检测模块之间的通信，所述检测模块包括检测电阻和第二信号处理模块，所述检测电阻与点火头并联，所述第二信号处理模块与所述检测电阻组成闭合回路，所述第二信号处理模块用于发出远低于起爆电压的低电压高频信号并检测点火头和检测电阻并联电路的电流，由于点火头在正常工作时具有阻抗特性，若点火头故障时，电路阻抗为：The digital electronic detonator includes a second two-bus communication serial port module, a detection module and an ignition head, and the second two-bus communication serial port module is connected with the detection module and the first two-bus communication serial port module respectively, and is connected to the first two-bus communication serial port through the first two-bus communication serial port module.

点火头可以正常工作时，电路阻抗为：When the ignition head can work normally, the circuit impedance is:
由上式可知：It can be seen from the above formula:
