Abstract
The invention relates to a method for preventing accidental charging of an electronic code detonator chip ignition capacitor and a circuit used by the method, and belongs to the electronic code detonator technology. The method is characterized by providing an electronic switch, wherein the electronic switch is arranged on an electronic code detonator chip and can connect a positive end of the ignition capacitor and a grounding end of an electronic system, so that the ignition capacitor is maintained at low level and cannot be charged; when receiving a charging command, the electronic switch is turned off, then a charging switch is turned on, and the ignition capacitor is charged; after the charging is completed, if the received command is a detonation command, the detonation is normally carried out according to the command; if the received command is not a detonation command, or a detonator cannot be fired after the detonation command is received, the electronic switch is immediately turned on, the electric energy in the ignition capacitor is discharged, and the mis-detonation can be avoided. The method can prevent the accidental charging of the electronic code detonator chip ignition capacitor, the circuit is simple and reliable, and the cost is low.
Description
Technical field
The invention belongs to the electronic cipher technology for detonators.
Background technology
The electronic cipher detonator also claims digital primer, electric detonator or digital intelligent detonator etc.Electronic cipher detonator collection cipher control, accurate delay, special use is detonated, fuzing information storage etc. is multi-functional.Be provided with control chip in the detonator, constituted by microprocessor, communication unit, state detection unit, charging ignition control unit, password identification unit, time-delay control module etc.In order to guarantee the security reliability of electronic cipher blasting cap initiation, need prevent the unexpected charging of its igniting electric capacity.
Summary of the invention
The object of the present invention is to provide a kind of method that prevents the unexpected charging of electronic cipher detonator chip igniting electric capacity, to guarantee the safe and reliable of electronic cipher blasting cap initiation.Another object of the present invention is to provide a kind of circuit of implementing said method.
The inventive method is as follows: establish an electronic switch, this electronic switch can be logical with the ground termination of anode and the electronic system of igniting electric capacity when electronic cipher detonator chip power is worked, thereby make the electric capacity of lighting a fire maintain low level and can not charge; After receiving charging instruction, this electronic switch cuts out, and opens charge switch immediately, charges to igniting electric capacity; After charging finishes, if what receive is fuze, then normally detonate by instruction; If what receive is not fuze, or detonator is failed real quick-friedly after the fuze of receiving, and then electronic switch is opened immediately, and electric energy is released in the igniting electric capacity, thereby it is quick-fried to avoid producing mistake.
The structure of implementing a kind of circuit of the inventive method is:
The colelctor electrode of one transistor is connected with first end, the output of charge switch and an end of bridge silk of igniting electric capacity, the second end ground connection of igniting electric capacity, the base stage of triode connects the charging instruction output of detonator chip, the grounded emitter of triode by a resistance.
The invention has the beneficial effects as follows that this method not only can prevent the unexpected charging of electronic cipher detonator chip igniting electric capacity, and it is simple and reliable to implement the circuit of this method, cost is low.
