Embodiment 1

[0075] In this embodiment, the type code of the electronic detonator is injected into the electronic detonator during the production stage, and the feature information is the extension of the electronic detonator as an example for illustration.

[0076] Step 101: Connect multiple electronic detonators with different types of codes in parallel to the same leg line. This step includes the following sub-steps:

[0077] Sub-step A1: Set the type code.

[0078] Assuming that the number of electronic detonators sharing the leg is 4, then set 4 type codes, which are 0, 1, 2 and 3 respectively.

[0079] Sub-step A2: Injecting the type code into the electronic detonator.

[0080] During the production process of each electronic detonator, a type code is randomly written into the memory of each electronic detonator control circuit.

[0081] Sub-step A3: Coat the body of the electronic detonator injected with the same type code with the same color.

[0082] In this example, paint the ...

Embodiment 2

[0102]In this embodiment, the type code of the electronic detonator is injected into the electronic detonator during the production stage, and the feature information is the network address of the electronic detonator as an example for illustration.

[0103] Step 201: Connect multiple electronic detonators with different types of codes in parallel to the same leg. The specific process of this step is exactly the same as sub-step A1-sub-step A4.

[0104] Step 202: Connect the foot wire with the electronic detonator signature reader.

[0105] Step 203: The electronic detonator characteristic reader / writer sends the type code and characteristic information to the four electronic detonators sharing the footline respectively according to the position of the footline in the detonation network.

[0106] In this example, the characteristic information is the network address of the electronic detonator, and the network address of the electronic detonator is set as the initiation branch...

Abstract

The invention discloses a communication method for multiple electronic detonators with a shared leg wire in the technical field of connection and communication design of electronic detonators. The method comprises the following steps: connecting multiple electronic detonators with different types of preset codes in parallel in the same leg wire; connecting the leg wire with an electronic detonator characteristic reader; respectively transmitting the type codes and characteristic information to the multiple electronic detonators connected to the leg wire in parallel by the electronic detonator characteristic reader; after the electronic detonators connected to the leg wire in parallel receive the type codes and characteristic information, storing the characteristic information and transmitting response information when the type codes transmitted by the electronic detonator characteristic reader are judged to be consistent with preset type codes; disconnecting connection between the leg wire and the electronic detonator characteristic reader after the characteristic information is stored in each electronic detonator which is connected in parallel with the leg wire, and connecting the leg wire into a detonation branch. The communication and recognition problems in the process of sharing the same leg wire among the multiple electronic detonators are solved, the construction convenience is improved, and the miss-fire rate of the electronic detonators is reduced.

Description

technical field [0001] The invention belongs to the technical field of electronic detonator connection and electronic detonator communication design, and in particular relates to a communication method for a plurality of electronic detonators sharing a leg line. Background technique [0002] Electronic detonators have gradually become common equipment in blasting engineering due to their accurate delay setting and safe controllability. During the blasting construction process, the usual initiation network such as figure 1 As shown, the structure is that a plurality of electronic detonators 1 are connected to their respective leg wires 2, and then the leg wires 2 are connected in parallel to the same detonating branch 3, and multiple detonating branches 3 are connected to the detonator to form a detonating net road. [0003] The existing electronic detonator detonation network has the following problems: [0004] (1) The construction process is complex and cumbersome, and ...
