Abstract

The invention relates to a communication circuit and method of an electronic detonator. The communication circuit comprises a communication interface, a filtering circuit, a first switch circuit, a second switch circuit, a single-chip microcomputer, a rectifying circuit and a voltage stabilizing circuit; an exploder modulates carrier waves through a modulation signal; a carrier wave signal is generated and sent to the communication circuit of the electronic detonator through a bus; the communication circuit demodulates the carrier wave signal and performs treatment; then a signal is sent to the exploder; and the communication process is completed. According to the communication circuit and method of the electronic detonator, communication is performed by means of a power line network, rewiring is not needed, the beneficial effects that the occupied space is small and the constructing and running cost is low are achieved, and transmission of a high-frequency signal and a lower-frequency signal is supported at the same time.

Description

technical field

[0001] The invention relates to the technical field of electronic detonators, in particular to a communication circuit and a communication method for electronic detonators. Background technique

[0002] The existing communication methods of electronic detonators mainly use M-BUS, RS-485, etc., but M-BUS is suitable for the transmission of low-frequency signals, and is prone to deformation when used to transmit high-frequency signals. RS-485 requires a dedicated Lines take up a lot of space and are not suitable for small electronic detonators. Contents of the invention

[0003] The invention provides a communication circuit for an electronic detonator, which adopts a power carrier communication method. The problem to be solved is that the M-BUS communication method used by the existing electronic detonator is not suitable for transmitting high-frequency signals, and the RS-485 communication method takes up less space. Many, not applicable to the technical p...
