Embodiment Construction

[0032] Core idea of ​​the present invention:

[0033] (1) Two-wire bus: non-polarity, half-duplex, serial asynchronous communication, high anti-interference two-wire bus that supports power supply and communication.

[0034] (2) Communication mechanism: The detonator and the digital electronic detonator are connected through a two-wire bus. The downlink adopts bus differential voltage amplitude or pulse width modulation, and the uplink adopts bus current amplitude or pulse width modulation.

[0035] (3) Network detonation: the detonator can be used as the main detonator or as a sub detonator, and the detonators can be connected through RS485 bus / Ethernet port RJ45 / wireless (5G / 4G / WIFI, etc.) way to communicate.

[0036] (4) Digital electronic detonator: support two-wire bus power supply and communication, receive, process and execute instructions from the detonator, and feed back information to the detonator, control the charging and discharging of the detonating capacitor an...
