Electronic detonator initiation system based on near field communication and control method of electronic detonator initiation system

Abstract

The invention discloses an electronic detonator initiation system based on near field communication and a control method of the electronic detonator initiation system. A relay is adopted to transmit a wireless communication signal from an initiation controller or an encoder to an electronic detonator in a wired communication signal mode, and feed feedback information of the electronic detonator to various commands of the initiation controller or the encoder back to the initiation controller or the encoder in a wireless communication signal mode, the encoder and the electronic detonator adopt near field communication in the register and delay time setting links, and the problem that an existing wireless electronic detonator initiation system is low in reliability and high in cost is effectively solved. Near field communication simplifies the register and delay time setting work of the electronic detonator on a blasting operation site, omits the physical connection work of the electronic detonator and the encoder in the register and delay time setting links, can greatly reduce the quantity of manual work, avoids faults and improves working efficiency. The near field communication distance between the encoder and the electronic detonator is short, and thus operation safety is ensured.

AI Technical Summary

Problems solved by technology

[0003] In the existing design scheme of the wireless electronic detonator detonation system, each wireless electronic detonator needs to be equipped with an independent power supply. Communication signal transceiver unit, so when implementing blasting operations, the project site preparation cycle and manual workload will be increased

The structure and circuit of the single-shot wireless electronic detonator are more complicated than the traditional wired electronic detonator, but its working reliability cannot be guaranteed at the same time, and the cost of the single-shot wireless electronic detonator is much higher than that of the traditional wired electronic detonator.

[0004] The main manual workload of the traditional electronic detonator detonation system at the blasting operation site is the registration and setting delay time of the electronic detonator. The operator needs to hold the encoder to record the ID number and setting delay time of each electronic detonator. In this During the process, each electronic detonator needs to be connected to the encoder through the signal bus interface in turn, and the early detonation controller and encoder have no positioning function, so the delay time needs to be allocated according to the position of the blast hole of the electronic detonator. The program is pre-written on the encoder, and then the registration of the electronic detonators at the corresponding positions and the delay time are set in sequence in strict accordance with the specific order. The on-site operators need to set up a large number of complicated wired connections at the blasting site, which may easily lead to wire failure. Short and broken faults, the work of retracting and unwinding the line is very large, the project site preparation period is long and the manual workload is large, resulting in low efficiency of registration and setting delay
