Description
Technical Field
The invention relates to the technical field of electronic detonators, in particular to a method, a system and a medium for realizing time-sharing charging of electronic detonators.
Background
The electronic detonators need to be networked in real explosion on site, the number of the commonly networked detonators is from dozens to hundreds, and the detonators and the electronic detonators are connected in parallel. The detonator usually adopts the battery power supply, because the detonator is limited in size, the battery that adopts also can not provide too big output power, when the electronic detonator that the network deployment inserts the detonator is more and charge to the high pressure simultaneously, can produce very big charging current on the generating line, on the one hand can be because of exceeding the biggest power initiation short circuit or overcurrent protection of detonator, on the other hand also can lead to partial electronic detonator can not charge target voltage or because input voltage is low reset excessively, whatever kind of condition, can all influence the anti-explosion of detonator.
The prior art mainly has several charging modes:
1. and serially charging one by one, and sequentially sending a single charging instruction to all electronic detonators of the network by the exploder one by one. Because the quantity of the electronic detonators is large during networking, the operation is complex, the integral charging time is long, and meanwhile, because the charging time interval between the first detonator and the last detonator is too long, the energy storage capacitor of the early-stage charged detonator can cause insufficient charging due to self electric leakage, thereby improving the probability of explosion rejection.
2. And in the voltage division charging mode, the charging voltage is divided into a plurality of voltage levels from low to high, and the detonator charges the energy storage capacitor in the electronic detonator by sending charging instructions of different voltage levels. In this way, the initiator needs to send a charging command for many times and needs to detect the charging voltage for many times to judge whether the initiator is full or not so as to enter the charging of the next voltage level, and the whole charging process is complex to process and has low reliability.
3. And in the sectional charging mode, numbering the detonators, randomly extracting part of the detonator set from the n numbered detonators at one time for charging, and after the detonator set is completely charged, taking part of the detonators from the rest detonators for charging until the detonator set is completely charged. The method has two disadvantages that on one hand, the detonator needs to perform additional numbering operation on the electronic detonator, and meanwhile, a special charging instruction according to the number value needs to be designed in the electronic detonator, so that the efficiency is still lower compared with the method of broadcasting the charging instruction (all detonators are charged simultaneously).

Two embodiments of the time-shared charging instruction:
the fast time-sharing charging instruction 1 is fixedly divided into 8 groups for time-sharing charging no matter how many electronic detonators are.

Charging can be completed faster for application scenes with a small networking quantity. By adopting the mode, the circuit is realized only by taking the high bit of the number value without an additional circuit.
Referring to fig. 5, the number value register in the figure is a number value generated by the detonator chip after the scanning feedback is completed, and is stored in the register.

Selecting corresponding data bits with different number values according to the group _ cfg, taking out the low effective 6 bits of the group number register, respectively sending the low effective 6 bits into a comparator for comparison, if the low effective 6 bits are equal, the output signal matched is 1, otherwise, the output signal is 0. The charge _ cmd is an effective signal generated by the digital circuit and analyzed to a charging instruction, and the effective charging enable signal charge _ en is really output to control the opening of a charging path only after the serial numbers are matched through the processing of an AND gate.
The embodiment of the invention provides a method, a system and a medium for realizing time-sharing charging of an electronic detonator, and the related electronic detonator chip comprises a function of automatically generating a serial number value according to a scanning instruction, and the serial number value is simultaneously returned to an exploder. After the networking scanning is finished, each generator detonator has a different number value N, the number value N starts from 1, and the maximum value is the number of detonators on line in the network. The detonator realizes time-sharing charging of the electronic detonators by a quick time-sharing charging method, specifically, a charging instruction adopts a broadcasting instruction, the instruction comprises a specific grouping mode to simultaneously charge a group of specified electronic detonators, and detonators in different groups realize time-sharing charging.
