1) Networking, connecting buses, sending a mode switching instruction, and setting the module mode as a networking mode (only once). The bus is continuously supplied with 16V at this time.

2) After the bus is powered for a period of time, 3 discharging instructions (at least 10ms intervals) are sent, and 3 detonator initialization instructions (at least 500ms intervals) are sent, wherein the instructions have certain requirements on the driving capability of the detonator battery.

3) And sending an instruction for acquiring the configuration information of the detonator, and acquiring the UID length, the detonation password length and the version information used by the detonator. When the version detection fails, the module does not receive other instructions except the power supply/disconnection of the bus in the fourth section, voltage and current acquisition, mode switching, detonator configuration information acquisition, discharging, detonator resetting, detonator initializing, bridge wire on-off measurement and energy storage capacitor measurement.
