Control system for initiation networks of electronic detonators

Abstract

The invention provides a control system of initiation networks of electronic detonators. The control system comprises an upper computer control module, an actuator module, an initiator control module, changeover switches and the initiation networks. A signal input end of the initiator control module is connected with the upper computer control module, an output end of the initiator control module is connected with the initiation networks by the corresponding changeover switches and is further connected with an input end of the actuator module, and an output end of the actuator module is connected with the corresponding changeover switches. The control system has the advantages that various initiators are respectively connected with corresponding initiation networks before initiation instructions are issued, and accordingly initiation network detection, delay setting and the like can be completed; the initiation networks are completely connected with actuators in a changeover manner during initiation, the initiation instructions are amplified via the actuators, accordingly, all the initiation networks can be actuated by the aid of sufficient actuation capacity, initiation precision loss due to the system can be prevented, and the control system is simple and is high in reliability.

Description

technical field [0001] The invention relates to the technical field of explosive detonation control, in particular to an electronic detonator detonation network control system. Background technique [0002] The electronic detonator detonator is the most important device of the electronic detonator system. It directly determines whether the electronic detonator can be reliably detonated and the networking capability of the detonation network. Due to cost and technical reasons, the maximum capacity that a single detonator can support generally does not exceed 500 However, the networking capability required for large-scale blasting will reach thousands to tens of thousands of rounds, which requires multiple detonators to be able to work in cascade. The existing cascading method generally adopts the master-slave method. In this method, the detonation command is sent from the master device to the slave device, and then sent from the slave device to the electronic detonator. The i...
