[ background of the invention ]

Electronic detonator blasting systems are widely used today and replace conventional blasting systems in many applications. Generally, the electronic detonator blasting system comprises an electronic detonator and an electronic detonator control device. The electronic detonator control device comprises a programmer and an initiator.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. And that the present invention may be practiced without these specific details. Those skilled in the art will be able to utilize the description and illustrations herein to effectively introduce other skilled in the art to their working essence. In other instances, well known methods and procedures have not been described in detail as they are readily understood, for the purpose of avoiding obscuring the present invention.

Reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with at least one implementation of the invention is included. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Fig. 1 is a block diagram of the blasting system according to an embodiment of the present invention. The blasting system includes a programmer and/or initiator 110, a plurality of electronic detonators 120, and a bus 130 connecting the programmer and/or initiator 110 and the electronic detonators 120. The bus 130 may be a twisted pair including a first connection line and a second connection line. The programmer 110 is in bidirectional data communication with the electronic detonator control circuit 122 of the electronic detonator 120 via the bus 130, and may also transfer energy to the electronic detonator control circuit 122 of the electronic detonator 120.

Due to the complex environment of a construction site, a plurality of electronic detonators are connected on a bus in parallel, so that lead wires grow disorderly, and the situation that some electronic detonators cannot normally explode frequently occurs on the construction site. After various improvements on the electronic detonator, the electronic detonator is still frequently detonated. Therefore the utility model provides a modified electron detonator is in order to improve the on-the-spot success rate of detonating of electron detonator.

Fig. 2 is a schematic diagram of an embodiment of the improved electronic detonator 120 of the present invention. The utility model provides an improvement job site's that modified electronic detonator 120 can be showing the detonation success rate of electronic detonator. The electronic detonator 120 comprises a tube shell 121, an electronic detonator control circuit 122 positioned in the tube shell 121, a tube plug 124 positioned at the tail part of the tube shell 121, a magnetic ring 123 positioned in the tube shell 121, and a leg wire 125 penetrating through the tube plug 124 and entering the tube shell 121. The leg wire 125 directly passes through the magnetic ring 123 or is wound on the magnetic ring 123 and then electrically connected to the electronic detonator control circuit 122. The electronic detonator 120 is electrically connected to the bus 130 via a leg wire 125. The number of the leg wires 125 is at least two, and each leg wire 125 directly passes through the magnetic ring 123 or is electrically connected with the electronic detonator control circuit 122 after being wound on the magnetic ring 123. The leg wire 125 may be wound around the magnetic ring 123 for one or more turns, and the number of turns may be set according to the requirement and application. The case 121 is made of metal. The magnetic ring 123 is located between the pipe plug 124 and the electronic detonator control circuit 122.

The electronic detonator 120 further comprises a blasting portion, and the electronic detonator control circuit 122 can control the blasting portion to detonate. To further reduce the area, the magnetic ring 123 may be integrated with the electronic detonator control circuit 122. In one embodiment, the electronic detonator control circuit 122 may comprise a semiconductor chip.

Through research on the electronic detonators which are not detonated on the spot, some electronic detonator control circuits 122 of the electronic detonators which are not detonated on the spot fail to work normally. In order to investigate the failure reason of the electronic detonator control circuit 122 of the electronic detonator which is not detonated in the field, a blasting test is subsequently carried out, and it is found that high-voltage pulses are sometimes generated on the bus 130 during blasting. The reason for the electronic detonator to fail in the construction site can be as follows: because the initiation sequence of the electronic detonators is inconsistent, and each electronic detonator is connected to the bus 130 during initiation, the electronic detonators initiated first may generate high-voltage pulses at the initiation moment, the voltage of the high-voltage pulses may reach tens of thousands of volts, the high-voltage pulses are transmitted to the electronic detonator control circuit 122 of the electronic detonators 120 which are not yet initiated through the commonly connected bus 130 through the leg wires 125, and the transmitted high-frequency high-voltage pulses may break down the electronic detonator control circuit 122 and discharge with the tube shell 121, so that the electronic detonator control circuit 122 may be disabled, and the electronic detonators 120 may be rejected; of course, it is also possible that the shock wave generated by the detonated electronic detonator 120 directly causes a high voltage pulse to be generated on the leg wire of another electronic detonator 120.

In the present invention, the magnetic ring 123 and the pin wire 125 passing through or wound around the magnetic ring are equivalent to a high frequency filter, which can effectively filter out the high frequency energy and signal entering through the pin wire 125, and when the high voltage pulse (which can be regarded as a high voltage high frequency signal) enters, because of the function of the magnetic ring 123. As shown in fig. 2, a high voltage is generated between the leg wire 125 at the plug 124 inside the tube case 121 and breaks down a medium (such as air) between the two to form a pulse discharge, as shown by the discharge indication in the region R in fig. 2, which prevents the high voltage pulse from being conducted to the electronic detonator control circuit 122, so as to achieve the purpose of protecting the electronic detonator control circuit.

Fig. 3 is a schematic block diagram of an electronic detonator according to another embodiment of the present invention. As shown in fig. 3, the electronic detonator in fig. 3 differs from the electronic detonator in fig. 2 in that: the magnetic ring 123 is arranged in the pipe plug 124, and the magnetic ring 123 is also arranged in the pipe shell 121, and the leg wire 125 enters the pipe plug 124 from the outside and then directly passes through the magnetic ring 123 in the pipe plug or is wound on the magnetic ring 123 in the pipe plug and then is electrically connected with the electronic detonator control circuit 122.

In one embodiment, the magnetic ring 123 and the plug 124 are integral. Preferably, the magnetic ring 123 may be directly injected into the plug 124, so that the electronic detonator is assembled in the same or similar manner as the electronic detonator without the magnetic ring 123.

The following are actual blast comparison tests: in certain tunnel construction in Guizhou, use current 500 electronic detonator (the electronic detonator who does not insert the magnetic ring) and the utility model discloses a blasting construction is done to modified 500 electronic detonator, and the network deployment scale is about 50 at every turn, and ordinary electronic detonator loses big gun 17 altogether and sends out, and the initiation success rate is 96.6%, and modified electronic detonator does not have the big gun of losing, and the success rate is 100%. Therefore, the success rate of detonation can be obviously improved by adopting the improved electronic detonator.

The foregoing description has disclosed fully the embodiments of the present invention. It should be noted that those skilled in the art can make modifications to the embodiments of the present invention without departing from the scope of the claims of the present invention. Accordingly, the scope of the claims of the present invention is not to be limited to the specific embodiments described above.
