Fig. 2 is a signal waveform diagram of an electronic detonator device providing a simulated detonation test in one or more embodiments, as shown. When the finished product of the electronic detonator needs to be tested, the working principle of providing the simulated detonation test is as follows:

(1) preparation before the simulated detonation test is performed.

First, the initiator may set the delay value of the electronic detonator to a small value to avoid long waiting times.

Secondly, completing the preposed detonation conditions for the electronic detonator, wherein the detonation conditions comprise: the method comprises the steps of detecting online, detecting faults, verifying detonator identification (UID) and detonation code (BMID), presetting a delay value and charging, wherein 2V gear (2V is a preset safe voltage value) can be selected as a charged voltage gear, and a digital logic circuit verifies an instruction sent by a detonator to pass.

(2) And carrying out a simulated detonation test.

The method comprises the following steps: and the initiator sends a detonation simulation instruction to the electronic detonator chip.

Step two: after the electronic detonator chip receives the simulation detonation instruction, the digital logic circuit judges whether the charging gear value is a preset safe voltage value and only charges once. If yes, executing the step three; otherwise, the instruction is exited and other commands are awaited.

The electronic detonator chip opens the detonating tube no matter the detonator sends the simulation detonating command or the detonating command. If the charging gear is an unsafe voltage gear, the voltage on the energy storage capacitor is a high voltage value for detonation, and then the detonator is detonated by opening the detonating tube, so that safety accidents are caused.

In the second step, the restriction that the charging control circuit is charged only once is used for limiting the charging times, and the main purpose is to prevent the situation that the high-voltage gear is charged first, but the safety gear is directly used again for charging without discharging. The two times of charging under the above conditions can make the voltage on the energy storage capacitor in the process of slowly declining from a high-grade value to a low-grade value, and at the moment, it is unsafe to open the detonating tube.

Step three: and the digital logic circuit of the electronic detonator chip starts delay timing, and the gear of the voltage comparator is set to be the lowest gear value. In one or more embodiments, the lowest gear value is set to 1V.

And in the time period from the time of entering delay timing to the time of resetting the electronic detonator chip, the electronic detonator chip is in a low power consumption mode. When the digital logic circuit receives the simulation detonation instruction, the internal part of the electronic detonator chip is automatically set to be the lowest gear value for comparing the voltage value of the second feedback, so that the circuits started in the delay period can be reduced, and the power consumption is reduced.

In addition, when the capacitor voltage is charged to the shift position, the charging is stopped, and the voltage is slowly lost. Since the simulated detonation is performed after the charging is carried out to 2V, after a certain period of time, the 2V gear is unreasonably used, and misjudgment can be caused, one or more embodiments of the invention set the gear to be the lowest gear value (1V).

Step four: when the delay timing is finished, the digital logic circuit controls the current feedback circuit to send a first feedback signal to mark the initiation of the initiating pipe.

Step five: and when the first feedback signal is finished, the digital logic circuit opens the detonating tube, and the energy storage capacitor starts to discharge. Because the embodiment is a simulated detonation test, the charging voltage is only 2V and is a safe voltage, and the electronic detonator cannot explode.

Step six: after the primary tube is opened for a period of time (such as 5ms), if the finished product test of the electronic detonator is normal, the energy storage capacitor is released and discharged, the value output by the voltage comparator is 0 at the moment, and the digital logic circuit receives the value and controls the current feedback circuit to generate feedback.

When the finished product test of the electronic detonator is abnormal, for example, the detonating tube cannot be opened, the voltage of the energy storage capacitor cannot be released, the value output by the voltage comparator is 1, the electronic detonator chip generates a second feedback signal, the feedback duration is a preset value (for example, 2ms), and the feedback duration is controlled by the digital logic circuit.

Step seven: after the feedback is finished or after a period of time, the electronic detonator chip enters a reset state.

Referring to fig. 1 and 2, dout is a feedback switch of the control current feedback circuit, fire is the control of the opening of the detonator, rst is the reset generated by the digital logic circuit, and the reset is started when the rst is 0. As can be seen from the waveforms of fig. 2, the waveform diagram of dout is a waveform diagram of generating the first feedback signal and the second feedback signal, and the waveform diagram of fire is a waveform diagram of opening the squib for a certain period of time. And Rst is a waveform diagram of the electronic detonator chip entering a reset state after the feedback is finished or after a certain time.

Fig. 3 is a flow diagram of a control method of an electronic detonator device providing a simulated detonation test in one or more embodiments, as shown.

A control method of an electronic detonator device for providing a simulated detonation test executes the following steps in the electronic detonator device for providing the simulated detonation test:

s1, receiving a simulated detonation instruction signal sent by a detonator by an electronic detonator chip.

Before the electronic detonator device of step S1 is subjected to the finished product test, the electronic detonator device satisfies the detonation condition, and the stage value of the charging voltage is set to 2V. In one or more embodiments, 2V is the safe voltage used for testing of the electronic detonator chip.

S2, the digital logic circuit of the electronic detonator chip judges whether the gear value of the charging voltage is a preset safe voltage value and the energy storage capacitor is charged only once, if so, the step S3 is executed, otherwise, the step S1 is returned to wait for instructions. Wherein, in one or more embodiments, the preset safe voltage value is 2V.

And S3, the electronic detonator chip enters delay timing, and after the delay timing is finished, a first feedback is sent to the initiator, and then the initiating pipe is opened. When the electronic detonator chip sends the first feedback signal, the electronic detonator chip is marked to start detonating. Step S3 specifically includes the following steps:

and S31, the electronic detonator chip enters delay timing, and the electronic detonator chip sets the gear of the voltage comparator to be the lowest gear value. Wherein, in one or more embodiments, the lowest gear value is 1V.

And S21, when the electronic detonator chip opens the detonating tube, the energy storage capacitor starts to discharge. Because the simulated detonation test of the electronic detonator is carried out, the gear value of the charging voltage is 2V, and 2V is a safe voltage value, the electronic detonator cannot explode.

And S4, after the detonating tube is opened for a preset time, judging whether the voltage of the energy storage capacitor is higher than the lowest gear value, if so, executing the step S5, otherwise, executing the step S6.

Wherein the preset time is set by a system, and in one or more embodiments, the preset time may be set to 5 ms.

And S5, sending a second feedback signal to the initiator to prompt the abnormality of the electronic detonator device.

When the electronic detonator is abnormal, for example, the detonating tube cannot be opened, so that the voltage of the energy storage capacitor cannot be released, the output value of the voltage comparator is 1, the electronic detonator chip generates a second feedback signal, the duration time of the second feedback signal is set by a system, in one or more embodiments, the duration time of the second feedback signal is set to 2ms, and after the second feedback signal is ended, the step S6 is performed.

S6, the electronic detonator chip enters a reset state.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
