Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the field of blasting, in particular to an electronic detonator and a blasting system.
[ 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. The electronic detonator comprises an electronic detonator control circuit and a detonator basic unit, wherein the electronic detonator control circuit is communicated with the electronic detonator control equipment and controls the electronic detonator to explode. Specifically, the programmer may perform various programming on the electronic detonators, such as programming the initiation delay time of each electronic detonator, and the like. The order of initiation of the individual electronic detonators is usually in a sequential relationship for a predetermined initiation effect.

Generally, the electronic detonator may receive energy from the electronic detonator control device via a pair of twisted pairs (buses) and perform bidirectional data transmission with the electronic detonator control device via the twisted pairs. Large explosions, such as those of dams, mountains or buildings, typically require tens or even hundreds of electronic detonators to cooperate.
However, when so many electronic detonators are detonated in the field, some electronic detonators often fail to detonate normally. How to ensure that all electronic detonators can normally detonate is always the research direction in the field.

[ detailed description ] embodiments
The detailed description of the invention generally describes procedures, steps, logic blocks, processes, or other symbolic representations that directly or indirectly simulate the operation of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. And the 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 so as not to obscure the present invention.
Reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic may be included in at least one implementation of the invention. 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 a blasting system 100 according to an embodiment of the invention. The blasting system 100 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 performs bidirectional data communication with the electronic detonator control circuit 121 of the electronic detonator 120 through the bus 130, and may also transmit energy to the electronic detonator control circuit 121 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 invention provides an improved electronic detonator to improve the success rate of the field initiation of the electronic detonator.
Fig. 2 is a schematic diagram of the improved electronic detonator 120 of the present invention in one embodiment. The improved electronic detonator 120 in the invention can obviously improve the detonation success rate of the electronic detonator in a construction site. 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 121 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 penetrating or wound thereon function as a high frequency filter, which can effectively filter high frequency energy and signals entering through the pin wire 125, and when a high voltage pulse (which can be regarded as a high voltage high frequency signal) enters, due to the function of the magnetic ring 123, as shown in fig. 2, a high voltage is generated between the pin 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 in the discharge indication of the R region in fig. 2, which prevents the high voltage pulse from being conducted to the electronic detonator control circuit 122, thereby achieving the purpose of protecting the electronic detonator control circuit.
The following are actual blast comparison tests: in the construction of a certain tunnel in Guizhou, the existing 500-generation electronic detonator (the electronic detonator without the inserted magnetic ring) and the improved 500-generation electronic detonator are used for blasting construction, the networking scale is about 50 in each time, the common electronic detonator loses 17 shots, the detonation success rate is 96.6 percent, the improved electronic detonator does not lose shots, and the success rate is 100 percent. Therefore, the success rate of detonation can be obviously improved by adopting the improved electronic detonator.
The foregoing description has disclosed fully preferred 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 appended claims. Accordingly, the scope of the appended claims is not to be limited to the specific embodiments described above.
