With the current frequent terrorist activities involving explosions abroad, there is an increasing need to prepare, deal with, prevent and dispose of explosive events in advance, which requires enhanced training of explosive disposal personnel for security inspection.

Currently, there are various ways of initiating explosive devices, including ignition, collision, and electrical initiation. Compared with ignition, mechanical friction, impact and other initiation modes, the electric initiation mode is more flexible and controllable. The electric initiation explosion device can set different attack modes aiming at different targets, so that the electric initiation explosion device has practical threat by adopting an electric initiation party.

The electric initiation and explosion device comprises an explosion device body and an electric initiation function module, wherein the electric initiation function module is provided with a corresponding electronic circuit and is used for generating a controlled initiation signal when triggered; the explosive device body receives a controlled initiation signal to trigger the detonation of an explosive. According to different detonation triggering modes of the electric detonation function module, the detonation triggering mode has various modes such as timing (generating a detonation signal according to set time), remote (generating a detonation signal according to a remote control signal), light control (generating a detonation signal according to an ambient light signal), magnetic control (generating a detonation signal according to ambient magnetic force or magnetic force change), lifting (the detonation device is lifted off a support to generate a detonation signal), direct (generating a detonation signal through direct triggering), inclination (generating a detonation signal when the temperature reaches a preset range), temperature control (generating a detonation signal when the temperature reaches a preset range), approach (generating a detonation signal when an infrared signal approaches), and the like.

The corresponding type of electric initiation functional module is used for generating a corresponding initiation signal when triggered, and the explosion simulator generates a corresponding simulation effect based on the initiation signal.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic diagram of a circuit of a remote-control multi-path simulated explosion training device according to an embodiment of the present invention. In this embodiment, the remote-controlled multi-path simulated explosion training device comprises a power supply unit 100 and an explosion simulator 200, and further comprises four simulation function units 310 and 340.

In this embodiment, the power supply unit 100 includes a battery pack U, a power selection switch K1, a power-up indication circuit, and a power-down indication circuit. The power-on indicating circuit comprises a resistor R1 and a light-emitting diode D1 which are connected in series, and the power-off indicating circuit comprises a resistor R2 and a light-emitting diode D2 which are connected in series. The battery pack U may consist of three 18650 rechargeable lithium batteries housed in a battery case, the red positive power terminal of which is connected to pin 1 of the power selection switch K1, and the black ground terminal of which is connected to the ground of the entire circuit. The state of a power supply selection switch K1 is changed, a movable contact 1 is in contact with a fixed contact 2, a power-on indicating circuit is powered on, the power-on indicating circuit is grounded through a resistor R1 and a diode D1, a diode D1 emits light to indicate the power-on state, and meanwhile electric energy is output outwards; when the movable contact 1 contacts with the fixed contact 3, the power-off indicating circuit is powered on, is grounded through the resistor R2 and the diode D2, and the diode D2 emits light to indicate the power-off state and stop outputting electric energy outwards.

The power supply unit 100 may be provided with a suitable charger, such as a charging module that may be a 220 volt ac input, a 12.6 volt dc output, to charge the battery pack U with ac or dc power.

As shown in the figure, each of the four analog function units 310-340 includes a function switch K11-K14, a control interface S21-S24 and a control relay J1-J4, which are correspondingly arranged, and are matched with the predetermined electric initiation function module.

The function selector switch K11-K14 may be a boat-shaped double blade switch, i.e. configured as a double blade switch, two blades being rotatably mounted on a switch base, the two blades being switchable between the III and I states by rotation. Each of the function switches K11-K14 is provided with terminals such as a power supply input terminal 10, a first power supply output terminal 11, a signal input terminal 20, and a signal first output terminal 21. By rotating the two knife switches, the function switch can control the power-on or power-off of the control interfaces S21-S24 and the control relays J1-J4. In the first state (I state) (rotation of the two blades), the power input 10 is in communication with the first power output 11, while the signal input 20 is in communication with the first signal output 21.

The four control relays J1-J4 include coil circuits and series normally open circuits Kj 1-Kj 4 cooperating with the coil circuits. The series of normally open circuits Kj 1-Kj 4 may be provided with a pair of normally open contacts. The coil circuit is electrified to generate magnetic force, the state of the series normally open circuit Kj 1-Kj 4 can be changed, and the normally open contact is switched to be in a closed state.

The control interfaces S21-S24 may be in plug-in engagement with predetermined electrical initiation function modules. The control interface S21-S24 can be provided with four pins, wherein pin 1 is a power pin for providing power for the electric initiation functional module. The pin 2 may be a ground terminal connected to a ground line. The pin 4 is a signal output pin, that is, when the electric initiation functional module meets a predetermined condition, an initiation signal is output (for example, when the predetermined condition is met, the signal output pin is communicated with the power supply pin, and is powered on and outputs a high-level signal). Pin 3 of control interface S21-S24 may be spare for empty pins.

As shown in the figure, the first power output end 11 of each function switch K11-K14 is communicated with the power input end of the corresponding control interface S21-S24, so as to supply power to the control interface S21-S24; the signal output ends of the control interfaces S21-S24 are communicated with the signal access end 20 of the corresponding function switch K10, so that the initiation signal (or the power-on signal) is transmitted to the signal access end 20.

The power supply access terminal 10 of each of the function switches K11-K14 is electrically connected to the power supply unit 100. As shown in the figure, the first signal output ends 21 of the four function switches K11-K14 are electrically connected with the input ends of the coil circuits of the control relays J1-J4 through diodes D7-D10 respectively.

In this embodiment, the four analog functional units 310-340 may be integrated into a box, and form a trigger signal output terminal 401 for outputting the initiation signal. The plurality of simulation function units 310-340 and the power supply unit 100 can be enclosed in the cartridge, so that the trainee can not change the parts in the cartridge 100. The box body can be packaged by using the existing packaging process so as to ensure the connection reliability of the electronic elements in the box body and avoid that other people randomly change circuits and parts in the box body.

As shown in the figure, in each analog function unit 310-340 in the present embodiment, the serial normally open circuits Kj 1-Kj 4 of the control relays J1-J4 are serially connected between the input terminal of the coil circuit of the control relay J1 and the trigger signal leading-out terminal 401 in the analog function unit 310 (left side in fig. 1), so that the serial normally open circuits Kj 1-Kj 4 form a serial structure, i.e., a plurality of electrical initiation function modules/control interfaces S21-S2 form an and relationship. And the trigger signal derivation end 401 is electrically connected with the explosion simulator 200 through a remote electric wire 402.

The remote wires 402 may have a suitable length, such as 40, 50, 60 … … 100 meters, to provide separation of the explosion simulator 200 from the cartridge (enclosing the power supply unit and the simulation function unit 310 and 340) and to provide remote monitoring or qualification of the training results in an area remote from the simulation function unit 310 and 340.

As shown, in this embodiment, the explosion simulator 200 includes an audible and visual alarm and a backup binding clip. The audible and visual alarm comprises an analog electric detonator, an indicator bulb and an analog explosive: the simulated electric detonator can be composed of a failed electric ignition head and a detonator shell, so that the appearance of the simulated electric detonator is consistent with that of a real electric detonator, and the training effect can be enhanced; meanwhile, indicator bulbs are connected in parallel at two ends of the analog electric detonator, so that whether explosion is triggered or not can be displayed. The simulated explosive can be a PVC pipe with the outer diameter of 32 mm, and the simulated explosive which is consistent with the color, appearance, property and imaging under X-ray of the real explosive is filled in the PVC pipe. The terminal clamps may be electrically connected to the respective explosion simulating means or may be connected to other parts as appropriate to suit different needs. The audible and visual alarm and the backup binding clip are connected to the remote wire 402 through an output selector switch K2. By switching the state of the output selection switch K2, the detonation signal can be transmitted to the audible and visual alarm and also to the jointing clamp.

The principle of the remote control multipath simulated explosion training device is as follows:

four electric initiation function modules with the same or different initiation modes are matched with the control interfaces S21-S24 (can be in plug-in matching) to prepare for the simulated explosion training.

The function switches K11-K14 are switched to a first state (I state), the power selection switch K1 is switched, the movable contact 1 and the fixed contact 2 are contacted, the power-on indicating circuit is powered on, and electric energy is output outwards. The power pin 1 of the control interface S21 is connected to the power unit 100 through the first power output terminal 11 and the power input terminal 10 of the function switch K11, and is powered on. The power supply terminal of the electrical initiation function module that cooperates with the control interface S21 is also powered.

In the same manner, the power terminals of the electrical initiation function modules cooperating with the control interfaces S22, S23, and S24 are also powered to provide for analog training.

At this time, if the electrical initiation function module configured at the control interface S21 satisfies the initiation condition (for example, the optically controlled electrical initiation function module, according to the ambient light satisfying the predetermined condition, the power pin 1 and the signal output pin are turned on, and a first initiation signal is generated), the first initiation signal reaches the diode D7 through the signal input terminal 20 and the signal first output terminal 21, and then reaches the coil circuit of the control relay J1 and is grounded, and the coil circuit is powered on to change the state of the control relay J1, so that the serial normally open circuit Kj1 matched with the coil circuit changes the state, and the normally open state is converted into the closed state. The first detonation signal continues through the series normally open circuit Kj1 in the closed state to the series normally open circuit Kj2 of the control relay J1. The first detonation signal stops because the series normally open circuit Kj2 is open.

At this time, if the electrical initiation function module configured in the control interface S22 meets the initiation condition, a second initiation signal is generated, and the second initiation signal reaches the diode D8 through the signal access terminal 20 and the signal first output terminal 21 of the analog function unit 320, and then reaches the coil circuit of the control relay J2 and is grounded, and the coil circuit is powered on to change the state of the control relay J2, so that the serial normally open circuit Kj2 matched with the coil circuit changes the state, and the normally open state is converted into the closed state. At this time, the second detonation signal and the first detonation signal (which may actually be an electrical signal with a high level, the same applies) continue to reach the series normally-open circuit Kj3 of the control relay J3 through the series normally-open circuit Kj2 in the closed state. The second detonation signal and the first detonation signal cease due to the series normally open circuit Kj3 being open.

By analogy, if the electric initiation function module configured at the control interface S23 meets the initiation condition, a third initiation signal is generated, the third initiation signal reaches the coil circuit of the control relay J3 and is grounded, the coil circuit is powered on, and the state of the control relay J3 is changed, so that the serial normally open circuit Kj3 matched with the coil circuit changes the state, and the normally open state is changed into the closed state. At this time, the third detonation signal, the second detonation signal and the first detonation signal continue to reach the series normally open circuit Kj4 of the control relay J4 through the series normally open circuit Kj3 in a closed state at the same time. The third firing signal, the second firing signal and the first firing signal cease due to the series normally open circuit Kj4 being open.

If the electric initiation function module configured in the control interface S24 meets the initiation condition, a fourth initiation signal is generated, and according to the same principle, the fourth initiation signal can close the series normally open circuit Kj4, so that the fourth initiation signal, the third initiation signal, the second initiation signal, and the first initiation signal reach the trigger signal lead-out end 401, and are electrically connected to the explosion simulator 200 through the remote wire 402, thereby performing explosive simulation.

It will be appreciated that this arrangement is utilised. A plurality of electric initiation functional modules with different initiation modes can be configured at the same time; the power supply access ends 10 of the four function switch switches K11-K14 are electrically connected with the power supply unit 100, the first signal output ends 21 are electrically connected with the input ends of the coil circuits of the control relays J1-J4 through diodes D7-D10, signal series connection of the analog function unit 310 and the signal series connection 340 can be achieved, the plurality of electric initiation function modules/control interfaces S21-S2 form an and relation, and the control interfaces S21-S24 and the electric initiation function modules can be powered on or powered off by combining state switching of the function switch switches K11-K14, so that security inspection, search and explosion-elimination personnel can train the plurality of corresponding electric initiation function modules, the basic principles and structures of various explosion devices can be known more conveniently, and training efficiency and effect are improved.

Meanwhile, the initiation signals of the plurality of analog function units 310 and 340 are collected to one trigger signal leading-out end 401, and the trigger signal leading-out end 401 is electrically connected with the explosion simulator 200 through a remote wire 402, so that the explosion simulator 200, the power supply unit 100 and the analog function units 310 and 340 can be separately arranged, favorable conditions are provided for remote monitoring and checking training, the simulation effects generated by the plurality of electric initiation function modules can be centrally managed, and convenience is provided for management and control of explosive ordnance disposal training.

In this embodiment, the independence of the analog functional units 310 and 340 is maintained by using the unidirectional conductive function of the diodes D7-D10, so as to avoid the inversion of the initiation signal.

According to the above description, it can be understood that the remote control multipath simulated explosion training device can be provided with an appropriate number of simulated functional units according to actual needs to meet training needs.

In the above embodiment, the series normally open circuits Kj 1-Kj 4 may be sequentially connected in series between the input terminal of the coil circuit of the control relay J1 and the trigger signal leading terminal 401 in the analog function unit 310, so that any one of the electric initiation function modules is not triggered, and when no initiation signal is generated, the explosion simulator 200 cannot be triggered.

According to actual needs, at least two of the series normally-open circuits may be connected in parallel between another series normally-open circuit and the trigger signal derivation end 401. Fig. 2 is a schematic diagram of a circuit of a remotely controlled multi-channel simulated explosion training device in another embodiment. The principle differs from that shown in fig. 1 in that: the series normally open circuits Kj3 and Kj4 are connected in parallel between the series normally open circuit Kj1 and the trigger signal derivation terminal 401. These two paths for the first initiation signal and the second initiation signal to reach the trigger signal output terminal 401: one path is through the series normally open circuit Kj3 and the other path is through the series normally open circuit Kj 4. Therefore, different combinations of a plurality of electric detonation functional modules can be realized, the adaptability of the simulated explosion training device is improved, and the number of training items is increased.

Referring to fig. 3, a schematic diagram of a circuit principle of a remotely controlled multi-channel simulated explosion training device in another embodiment is different from the embodiment shown in fig. 1 in that the function switches K11-K14 further include a second power output terminal 12 and a second signal output terminal 22, respectively. The second power output 12 communicates with the power inputs of the corresponding control interfaces S21-S24. The second signal output terminal 22 of each of the function switches K11-K14 is connected to the trigger signal output terminal 401 through a diode D3-D6.

The function switch may be a double-pole double-throw switch, and the two blades rotate in the other direction to switch to the second state (II state). In the second state of the function switch, the power input end 10 is communicated with the second power output end 12, and the signal input end 20 is communicated with the second signal output end 22. Therefore, the parallel connection of a plurality of control interfaces S21-S24/electric detonation functional modules can be realized, the adaptability of the simulated explosion training device is improved, and the number of training items is increased. The second signal output end 22 of each of the function switches K11-K14 is connected to the trigger signal output end 401 through the diodes D3-D6, so that the interaction between different control interfaces S21-S24/electric initiation function modules can be avoided.

In this embodiment, the plurality of control ports S21-S24/electrical initiation function modules are in a parallel relationship, i.e., the plurality of electrical initiation function modules/control ports S21-S2 are in an "OR" relationship. The second signal output end 22 of each of the function switches K11-K1 is connected to the trigger signal output end 401 through the diodes D3-D6, so that the interaction between different control interfaces S21-S2/electric initiation function modules can be avoided. Thus, the function switch of the corresponding simulation function unit 310-340 is in the second state, and the plurality of control interfaces S21-S24/electric initiation function modules can be trained respectively, so that the adaptability of the simulation explosion training device can be improved, and the number of training items can be increased. If the function switch K11 can be set to the second state, the power input terminal 10 is communicated with the second power output terminal 12, the signal input terminal 20 is communicated with the second signal output terminal 22, and the control interface S21/electric initiation function module is set to the power-on state, ready for the training of simulated explosion. Meanwhile, the function switch K11 is in state III (third state), and the power supply input terminal 10 is kept separate from both the first power supply output terminal 11 and the second power supply output terminal 12; the signal access end 20, the signal first output end 21 and the signal second output end 22 are kept separated, and the control interface S21/electric initiation functional module is in a power-off state.

Similarly, any one, any two or any three of the function switches K11-K14 can be in the power-on state, so as to provide a precondition for performing corresponding training.

When the function changing switch K11 is in the first state (I state), the operation principle thereof can be referred to the description of the embodiment shown in fig. 1.

Referring to fig. 4, a schematic diagram of a circuit of a remotely controlled multi-circuit simulated explosion training device in another embodiment is shown. Compared with the embodiment shown in fig. 3, in this embodiment, each of the analog function units 310 and 340 control relays J1-J4 further includes a normally open holding circuit Ki 1-Ki 4 cooperating with the coil circuit. Two ends of a holding normally-open circuit Ki 1-Ki 4 are respectively and electrically connected with the input end of the coil circuit and the corresponding first power output end 11 of the function switch K11-K12. Thus, the state of the series normally open circuit Kj 1-Kj 4 and the state of the holding normally open circuit Ki 1-Ki 4 can be changed by electrifying the coil circuit to generate magnetic force, so that the normally open contacts of the series normally open circuit Kj 1-Kj 4 and the holding normally open circuit Ki 1-Ki 4 are switched to be in a closed state.

Because the holding normally open circuit Ki 1-Ki 4 is arranged, after the corresponding control interfaces S21-S24 are matched with the electric initiation function module to trigger, the coil circuit is electrified to close the contacts of the holding normally open circuit Ki 1-Ki 4; because the two ends of the retentive normally open circuit Ki 1-Ki 4 are respectively electrically connected with the input end of the coil circuit and the first power output end 11 of the corresponding function change-over switch K11-K12, the corresponding coil circuit can be kept communicated, namely, the state of the electric circuit is kept, and the series circuit of the corresponding function change-over switch K11-K12 is kept communicated, the training process can be better determined, the training effect is further improved, and the explosive training management and training and examination can be conveniently simulated.

The specific scene is as follows: after the electric initiation function modules matched with the four control interfaces S21-S24 are triggered and then successfully send initiation signals to the explosion simulator 300 under the AND state by enabling each function switch K11 to be in a first state (I state), and enabling the simulation function unit 310 and 340 to be in an AND state, because the first power output end 11 and the control relays J1-J4 of the four function switches K11 are powered on, an electric loop is formed among the power unit 100, the power access end 10, the first power output end 11, the corresponding coil circuit and the ground wire, and further the serial circuits of the corresponding retainable normally open circuits Ki 1-Ki 4 are kept communicated. At this time, even if any one of the electrical initiation function modules cooperating with the control interface (e.g., the control interface S22) no longer outputs the initiation signal, the corresponding holding normally-open circuit (e.g., Ki2) remains open, and the four analog function units 310-34 can be kept in the and state. At the moment, other electric initiation functional modules can be normally powered on to carry out corresponding training, and then training items are added; meanwhile, as long as the corresponding electric initiation function module (such as the electric initiation function module matched with the control interface S22) is triggered, the corresponding holding normally open circuit (such as Ki2) is communicated, and then according to the state of the holding normally open circuit Ki2, whether the corresponding electric initiation function module is triggered or not can be determined, so that the training process can be tracked, and the training, examination and supervision are facilitated.

It is understood that, when the function selector switch is in the third state (state III), the power input terminal 10, the first power output terminal 11 and the second power output terminal 12 are kept disconnected; the signal access end 20, the signal first output end 21 and the signal second output end 22 are kept disconnected, so that power can be lost for each part, and the function switch K11-K14 and the control relay J1-J4 are reset.

As shown in fig. 4, in this embodiment, each of the analog functional units 310-340 further includes a power-on indicating device, one end of the power-on indicating device is electrically connected to the power input terminals of the control interfaces S21-S24, and the other end is grounded. Thus, when the power pins of the control interfaces S21-S24 are powered on, the power-on indicating device displays. Similarly, each of the analog functional units 310-340 further includes a trigger indicating device, one end of the trigger indicating device is electrically connected to the signal output end of the control interface S21-S24, and the other end is grounded; therefore, when the corresponding electric initiation functional module is triggered and the electric signal output pin outputs an initiation signal, the trigger indicating device can indicate the trigger state. It is understood that the power-on and trigger indicators may be light emitting diodes D11 and D12. In this embodiment, the anode D11 of the diode for power-up indication is electrically connected to the power input terminal, the anode D12 of the diode for power-down indication is electrically connected to the signal output terminal, the cathodes of the diodes D11 and D12 are connected and grounded through the safety resistor R3, and the diodes can avoid the mutual influence of the power-up indication circuit and the power-down indication circuit.

As shown in fig. 5, fig. 5 is a schematic layout diagram of the remote-controlled multi-path simulated explosion training device shown in fig. 4, which may include a closed box 400, in which the power unit 100 and the simulation function unit 310 and 340 are closed, and the explosion simulator 200 is located outside the box. The box body can be packaged by using the existing packaging process so as to ensure the connection reliability of the electronic elements in the box body and avoid that other people randomly change circuits and parts in the box body.
