Abstract

The invention provides a communication protocol and a communication method for an electronic fuse. Downlink data '0' and '1' are coded by downlink communication according to the relative duration of high level and low level in a bus voltage difference waveform, so that the requirement for the clock matching degree between an exploder and the electronic fuse is lowered; and after electronic fuse sends uplink communication data, the exploder immediately feeds the communication data back to the electronic fuse downward, so that the electronic fuse confirms whether the uplink communication data iscorrectly received or not.

Description

technical field [0001] The invention relates to the field of electronic fuzes, in particular to a communication protocol and a communication method for electronic fuzes. Background technique [0002] The electronic fuze uses two-bus technology to form a communication network with the detonator. As attached to the description of the present invention figure 1 As shown, bus 1 and bus 2 are both power supply lines and signal lines. Generally speaking, the downlink communication (communication from the detonator to the electronic fuze) encodes the downlink data according to the voltage signal, and specifically encodes the downlink data according to the bus voltage waveform, wherein the bus voltage waveform is the waveform of the voltage difference between bus 1 and bus 2. Similarly, the uplink communication (communication from the electronic fuze to the detonator) sends uplink data through the current signal, specifically, the electronic fuze sends uplink data to the detonator...
