Description

Technical Field

[0001] The invention relates to the technical field of security inspection, search and disposal of explosives and explosives, and in particular to a simulated explosion training device with exposed wires used by professional security inspectors and search and disposal of explosives personnel for practical training. Background Art

[0002] It is becoming increasingly urgent to prepare for, respond to, prevent and deal with explosion incidents in advance, which requires strengthening the training of security inspection and bomb disposal personnel in the disposal of explosive devices.

[0003] At present, there are many ways to detonate explosive devices, including pulling fire, collision and electric detonation. Compared with ignition, mechanical friction, impact and other detonation methods, electric detonation is more flexible and controllable. Electric detonation explosive devices can set different attack methods for different targets, so electric detonation explosive devices use electric detonation methods to pose a more realistic threat.

[0004] The electric detonation explosive device includes an explosive device body and an electric detonation functional module. The electric detonation functional module is provided with corresponding electronic circuits for generating a controlled detonation signal when triggered; the explosive device body receives the controlled detonation signal and triggers the explosion of the explosive. According to the different detonation triggering modes of the electric detonation functional module, the detonation triggering modes include timing (generating a detonation signal at a 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 lines or magnetic force changes), lifting (generating a detonation signal when the explosive device is lifted away from the support), direct (generating a detonation signal through direct triggering), tilting (generating a detonation signal when tilted at a predetermined angle), temperature control (generating a detonation signal when the temperature reaches a preset range), proximity (generating a detonation signal when an infrared signal approaches), and the like. Summary of the invention

[0005] The remote-controlled multi-channel simulated explosion training device provided by the present invention comprises a power supply unit and an explosion simulator, and also comprises at least two simulation function units;

[0006] The analog function units all include a correspondingly arranged function switching switch, a control interface and a control relay; the function switching switch is provided with a power supply access terminal, a first power supply output terminal, a signal access terminal and a first signal output terminal; in the first state of the function switching switch, the power supply access terminal is connected to the first power supply output terminal, and the signal access terminal is connected to the first signal output terminal; the control relay includes a coil circuit and a series normally open circuit coordinated with the coil circuit;

[0007] The first power output terminal of the function switching switch is connected to the corresponding power input terminal of the control interface; the signal output terminal of the control interface is connected to the corresponding signal input terminal of the function switching switch;

[0008] The power supply input end of each function switching switch is electrically connected to the power supply unit; the first signal output end of each function switching switch is electrically connected to the input end of the coil circuit of the control relay through a diode;

[0009] At least two of the series normally open circuits are connected in series between an input terminal of the control relay coil circuit and a trigger signal derivation terminal in one of the analog function units;

[0010] The trigger signal derivation end is electrically connected to the explosion simulator via a remote wire.

[0011] Since in the device, each simulation function unit includes a control interface, that is, the simulation explosion training device includes multiple control interfaces that cooperate with predetermined electric detonation function modules, at least two electric detonation function modules with different detonation methods can be configured at the same time; since the power access end of each function switching switch is electrically connected to the power supply unit and the first signal output end is electrically connected to the input end of the coil circuit of the control relay through a diode; the unidirectional conductive function of the diode can be used to maintain the independence of each simulation function unit; at the same time, the series normally open circuits of the two control relays are connected in series between the input end and the trigger signal export end of the control relay coil circuit in one of the simulation function units, so that the simulation function unit signal series connection can be realized; combined with the state switching of the function switching switch, the control interface and the electric detonation function module can be powered on or off, so that security inspection and bomb disposal personnel can be trained on multiple corresponding electric detonation function modules, and more conveniently understand the basic principles and structures of various explosive devices, thereby improving training efficiency and effect. At the same time, multiple simulation function units form a trigger signal export end, and the trigger signal export end is electrically connected to the explosion simulator through a remote wire. In this way, the explosion simulator can be separated from the power supply unit and the simulation function unit, thereby providing favorable conditions for remote monitoring and assessment training, and the simulation effects produced by multiple electric detonation function modules can also be centrally managed, thereby providing convenience for the management and control of bomb disposal training.

[0012] A further optional technical solution includes four simulation function units, which can make it easier for security inspection and bomb disposal personnel to understand the basic principles and structures of various explosive devices.

[0013] In a further optional technical solution, each of the series normally open circuits is sequentially connected in series between the input end of the control relay coil circuit and the trigger signal derivation end in one of the simulation function units, or at least two of the series normally open circuits are connected in parallel between another series normally open circuit and the trigger signal derivation end. In this way, different combinations of multiple electric detonation function modules can be realized, the adaptability of the simulation explosion training device can be improved, and the number of training items can be increased.

[0014] In a further technical solution, the function switching switch also includes a second power output terminal and a second signal output terminal, the second power output terminal is connected to the corresponding power input terminal of the control interface; the second signal output terminal of each function switching switch is connected to the trigger signal output terminal through a diode; when the function switching switch is in the second state, the power access terminal is connected to the second power output terminal, and the signal access terminal is connected to the second signal output terminal. In this way, multiple control interfaces / electric detonation function modules can be connected in parallel, the adaptability of the simulated explosion training device can be improved, and the number of training items can be increased. The second signal output terminal of each function switching switch is connected to the trigger signal output terminal through a diode, which can avoid mutual influence between different control interfaces / electric detonation function modules.

[0015] In a further technical solution, the control relay further includes a retentive normally open circuit that cooperates with the coil circuit; the two ends of the retentive normally open circuit are electrically connected to the input end of the coil circuit and the first power output end of the corresponding function switching switch, respectively. In this way, after the corresponding control interface cooperates with the electric detonation function module to trigger, the retentive normally open circuit can keep the coil circuit connected, thereby keeping the series circuits of the different function switching switches connected, which can better determine the training process, thereby improving the training effect, and facilitating the management of simulated explosion training and training assessment.

[0016] In a further technical solution, when the function switch is in the third state, the power input terminal, the first power output terminal and the second power output terminal remain disconnected; the signal input terminal, the first signal output terminal and the second signal output terminal remain disconnected. In this way, each analog functional unit can be powered off, thereby facilitating the resetting of the analog functional unit.

[0017] In a further technical solution, the simulation function unit further includes a power-on indication device, one end of which is electrically connected to the power input end of the control interface, and the other end can be grounded; or, further includes a trigger indication device, one end of which is electrically connected to the signal output end of the control interface, and the other end can be grounded. This allows trainees to better determine the state of the explosion training device and improve the training effect.

[0018] In the preferred technical solution, the explosion training device comprises a closed box body, the power supply unit and the simulation function unit are closed in the box body, and the explosion simulator is located outside the box body. This can facilitate the disposal of the explosion training device, facilitate training management, and improve training effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] Please refer to Figure 1 , Figure 1 The circuit principle diagram of a remote-controlled multi-channel explosion simulation training device in one embodiment of the present invention is shown in FIG. In this embodiment, the remote-controlled multi-channel explosion simulation training device includes a power supply unit 100 and an explosion simulator 200, and also includes four simulation function units 310-340.

[0032] In this embodiment, the power supply unit 100 includes a battery pack U, a power selection switch K1, a power-on indication circuit and a power-off indication circuit. Among them, the power-on indication circuit includes a resistor R1 and a light-emitting diode D1 connected in series, and the power-off indication circuit includes a resistor R2 and a light-emitting diode D2 connected in series. The battery pack U can be composed of three 18650 rechargeable lithium batteries placed in a battery box, the red positive power terminal of the battery box is connected to the 1st pin of the power selection switch K1, and the black ground terminal of the battery box is connected to the ground wire of the entire circuit. When the state of the power selection switch K1 is changed, the moving contact 1 and the static contact 2 are in contact, the power-on indication circuit is powered on, grounded through the resistor R1 and the diode D1, the diode D1 emits light, indicates the power-on state, and outputs electric energy to the outside; when the moving contact 1 and the static contact 3 are in contact, the power-off indication circuit is powered on, grounded through the resistor R2 and the diode D2, the diode D2 emits light, indicates the power-off state, and stops outputting electric energy to the outside.

[0033] The power supply unit 100 may be configured with a suitable charger, such as a charging module with a 220V AC input and a 12.6V DC output, so as to charge the battery pack U with AC or DC power.

[0034] As shown in the figure, the four simulation function units 310-340 each include correspondingly arranged function switching switches K11-K14, control interfaces S21-S24 cooperating with predetermined electrical detonation function modules, and control relays J1-J4.

[0035] The function switching switches K11-K14 can be a boat-shaped double-blade switch, that is, a double-blade switch, and the two blades can be rotatably installed on the switch base. Rotating the two blades can switch between the III and I states. Each function switching switch K11-K14 is provided with terminals such as a power supply access terminal 10, a first power supply output terminal 11, a signal access terminal 20, and a first signal output terminal 21. By rotating the two blades, the function switching switch can control the power on or off of the control interface S21-S24 and the control relay J1-J4. In the first state (I state) (rotating under the two blades), the power supply access terminal 10 is connected to the first power supply output terminal 11, and the signal access terminal 20 is connected to the first signal output terminal 21.

[0036] The four control relays J1-J4 include a coil circuit and a series normally open circuit Kj1-Kj4 that cooperates with the coil circuit. The series normally open circuit Kj1-Kj4 can be provided with a pair of normally open contacts. The coil circuit generates magnetic force, which can change the state of the series normally open circuit Kj1-Kj4, and the normally open contact is switched to a closed state.

[0037] The control interface S21-S24 can be plugged and matched with a predetermined electric detonation function module. The control interface S21-S24 can be provided with four pins, and pin 1 is a power pin, which provides power for the electric detonation function module. Pin 2 can be a ground terminal, connected to a ground wire. Pin 4 is a signal output pin, that is, when the electric detonation function module meets a predetermined condition, a detonation signal is output (for example, when the predetermined condition is met, the signal output pin is connected to the power pin, powered on, and a high-level signal is output). Pin 3 of the control interface S21-S24 can be an empty pin for standby.

[0038] As shown in the figure, the first power output terminal 11 of each function switching switch K11-K14 is connected to the power input terminal of the corresponding control interface S21-S24 to supply power to the control interface S21-S24; the signal output terminal of the control interface S21-S24 is connected to the signal access terminal 20 of the corresponding function switching switch K10 to transmit the detonation signal (or power-on signal) to the signal access terminal 20.

[0039] The power supply input terminal 10 of each of the function switching switches K11-K14 is electrically connected to the power supply unit 100. As shown in the figure, the first signal output terminals 21 of the four function switching switches K11-K14 are electrically connected to the input terminals of the coil circuits of the control relays J1-J4 through diodes D7-D10 respectively.

[0040] In this embodiment, four analog function units 310-340 can be integrated in a box body and form a trigger signal output terminal 401 for outputting a detonation signal. Multiple analog function units 310-340 and the power supply unit 100 can be enclosed in the box body, so that the trained personnel cannot modify the parts in the box body 100. The box body can be packaged using existing packaging processes to ensure the reliability of the connection of electronic components in the box body, while preventing others from arbitrarily changing the circuits and components in the box body.

[0041] As shown in the figure, in this embodiment, in each analog functional unit 310-340, the series normally open circuits Kj1-Kj4 of the control relays J1-J4 are connected in series to the analog functional unit 310 ( Figure 1 The input end of the control relay J1 coil circuit and the trigger signal output end 401 are connected between the series normally open circuits Kj1-Kj4 to form a series structure, that is, multiple electric detonation function modules / control interfaces S21-S2 form an "AND" relationship. The trigger signal output end 401 is electrically connected to the explosion simulator 200 through a remote wire 402.

[0042] The remote wire 402 can have an appropriate length, such as 40, 50, 60...100 meters, to separate the explosion simulator 200 and the box body (enclosing the power supply unit and the simulation function units 310-340), and be set in an area far away from the simulation function units 310-340 to remotely monitor or evaluate the training results.

[0043] As shown in the figure, in this embodiment, the explosion simulator 200 includes an audible and visual alarm and a spare wiring clamp. The audible and visual alarm includes a simulated electric detonator, an indicator bulb and a simulated explosive: the simulated electric detonator can be composed of an ineffective electric ignition head and a detonator shell, so that its appearance is consistent with the real electric detonator, which can enhance the training effect; at the same time, the indicator bulbs are connected in parallel at both ends of the simulated electric detonator to display whether the explosion is triggered. The simulated explosive can be a 32 mm outer diameter PVC pipe, which contains simulated explosives that are consistent with the color, appearance, properties, and X-ray imaging of the real explosive. The wiring clamp can be electrically connected to the corresponding explosion simulation device, or it can be connected to other appropriate parts to meet different needs. The audible and visual alarm and the spare wiring clamp are connected to the remote wire 402 through the output selection switch K2. By changing the state of the output selection switch K2, the detonation signal can be transmitted to the audible and visual alarm or to the wiring clamp.

[0044] The principle of the remote-controlled multi-channel simulated explosion training device is as follows:

[0045] The four electric detonation function modules with the same or different detonation modes are matched with the control interfaces S21-S24 (can be plug-in matched) to prepare for simulated explosion training.

[0046] Switch each function switch K11-K14 to the first state (I state), switch the power selection switch K1, make the moving contact 1 and the static contact 2 contact, the power-on indication circuit is powered on, and outputs electric energy to the outside. The power pin 1 of the control interface S21 is connected to the power supply unit 100 through the first power output terminal 11 and the power access terminal 10 of the function switch K11, and powered on. The power supply terminal of the electric detonation function module matched with the control interface S21 is also powered on.

[0047] In the same way, the power supply end of the electric detonation function module cooperating with the control interfaces S22, S23 and S24 is also powered on to prepare for the simulation training.

[0048] At this time, if the electric detonation function module configured by the control interface S21 meets the detonation condition (such as the light-controlled electric detonation function module, according to the ambient light meets the predetermined condition, so that its power pin 1 and the signal output pin are turned on, thereby generating the first detonation signal), the first detonation signal will reach the diode D7 through the signal access terminal 20 and the first signal output terminal 21, and then reach the coil circuit of the control relay J1 and ground. The coil circuit is powered on to change the state of the control relay J1, so that the series normally open circuit Kj1 matched with the coil circuit changes its state from the normally open state to the closed state. The first detonation signal continues to reach the series normally open circuit Kj2 of the control relay J1 through the closed state of the series normally open circuit Kj1. Since the series normally open circuit Kj2 is disconnected, the first detonation signal stops.

[0049] At this time, if the electric detonation function module configured by the control interface S22 meets the detonation condition and generates a second detonation signal, the second detonation signal will reach the diode D8 through the signal access terminal 20 and the first signal output terminal 21 of the analog function unit 320, and then reach the coil circuit of the control relay J2 and be grounded. The coil circuit is powered on, and the state of the control relay J2 is changed, so that the series normally open circuit Kj2 matched with the coil circuit changes state from the normally open state to the closed state. At this time, the second detonation signal and the first detonation signal (which can actually be a high-level electrical signal, the same below) will simultaneously continue to reach the series normally open circuit Kj3 of the control relay J3 through the closed state of the series normally open circuit Kj2. Since the series normally open circuit Kj3 is disconnected, the second detonation signal and the first detonation signal stop.

[0050] By analogy, if the electric detonation function module configured by the control interface S23 meets the detonation condition and generates a third detonation signal, the third detonation signal will reach the coil circuit of the control relay J3 and be grounded, the coil circuit will be powered on, and the state of the control relay J3 will be changed, so that the series normally open circuit Kj3 coordinated with the coil circuit will change state from the normally open state to the closed state. At this time, the third detonation signal, the second detonation signal and the first detonation signal will simultaneously continue to reach the series normally open circuit Kj4 of the control relay J4 through the series normally open circuit Kj3 in the closed state. Since the series normally open circuit Kj4 is disconnected, the third detonation signal, the second detonation signal and the first detonation signal stop.

[0051] If the electric detonation function module configured by the control interface S24 meets the detonation conditions and generates a fourth detonation signal, the fourth detonation signal can close the series normally open circuit Kj4 according to the same principle, so that the fourth detonation signal, the third detonation signal, the second detonation signal and the first detonation signal reach the trigger signal export terminal 401, and are electrically connected to the explosion simulator 200 through the remote wire 402, so as to perform an explosion simulation.

[0052] It can be understood that, by using the device, multiple electric detonation function modules with different detonation modes can be configured at the same time; the power supply access terminals 10 of the four function switching switches K11-K14 are all electrically connected to the power supply unit 100, and the first signal output terminal 21 is electrically connected to the input terminal of the coil circuit of the control relay J1-J4 through the diode D7-D10, so that the analog function unit 310-340 signal series connection can be realized, and multiple electric detonation function modules / control interfaces S21-S2 form an "and" relationship, and combined with the state switching of the function switching switches K11-K14, the control interface S21-S24 and the electric detonation function module can be powered on or off, so that the security inspection and bomb disposal personnel can be trained for multiple corresponding electric detonation function modules, and more conveniently understand the basic principles and structures of various explosive devices, thereby improving the training efficiency and effect.

[0053] At the same time, the detonation signals of multiple simulation function units 310-340 are collected into a trigger signal export terminal 401, and the trigger signal export terminal 401 is electrically connected to the explosion simulator 200 through a remote wire 402. In this way, the explosion simulator 200 can be separated from the power supply unit 100 and the simulation function units 310-340, thereby providing favorable conditions for remote monitoring and assessment training, and the simulation effects produced by multiple electric detonation function modules can also be centrally managed, thereby providing convenience for the management and control of bomb disposal training.

[0054] In this embodiment, the unidirectional conductive function of the diodes D7 - D10 is used to maintain the independence of the analog functional units 310 - 340 , thereby avoiding the reversal of the detonation signal.

[0055] According to the above description, it can be understood that the remote-controlled multi-channel simulated explosion training device can be provided with an appropriate number of simulation function units according to actual needs to meet training needs.

[0056] In the above embodiment, each series normally open circuit Kj1-Kj4 can be sequentially connected in series between the input end of the control relay J1 coil circuit in the simulation function unit 310 and the trigger signal output end 401, so that when any electric detonation function module is not triggered and no detonation signal is generated, the explosion simulator 200 cannot be triggered.

[0057] According to actual needs, at least two of the series normally open circuits can be connected in parallel between another series normally open circuit and the trigger signal derivation terminal 401. Figure 2 Another embodiment of the remote control multi-channel simulation explosion training device circuit schematic diagram is shown. Figure 1 The principle shown is different 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. In this way, the first detonation signal and the second detonation signal have two ways to reach the trigger signal derivation terminal 401: one way is through the series normally open circuit Kj3, and the other way is through the series normally open circuit Kj4. In this way, different combinations of multiple electric detonation function modules can be realized, the adaptability of the simulated explosion training device can be improved, and the number of training items can be increased.

[0058] Please refer to Figure 3 , the figure is another embodiment of the remote control multi-channel simulation explosion training device circuit principle diagram, and Figure 1 Compared with the embodiment shown in , the difference is that the function switching switches K11-K14 also include a second power output terminal 12 and a second signal output terminal 22. The second power output terminal 12 is connected to the power input terminal of the corresponding control interface S21-S24. The second signal output terminal 22 of each function switching switch K11-K14 is connected to the trigger signal derivation terminal 401 through the diode D3-D6.

[0059] The function switching switch can be a double-pole double-throw switch, and the two switches rotate in the other direction to switch to the second state (II state). In the second state of the function switching switch, the power access terminal 10 is connected to the second power output terminal 12, and the signal access terminal 20 is connected to the second signal output terminal 22. In this way, multiple control interfaces S21-S24 / electric detonation function modules can be connected in parallel, the adaptability of the simulated explosion training device can be improved, and the number of training items can be increased. The second signal output terminal 22 of each of the function switching switches K11-K14 is connected to the trigger signal derivation terminal 401 through the diodes D3-D6, which can avoid the mutual influence of different control interfaces S21-S24 / electric detonation function modules.

[0060] In this embodiment, multiple control interfaces S21-S24 / electric detonation function modules form a parallel relationship, that is, multiple electric detonation function modules / control interfaces S21-S2 form an "or" relationship. The second signal output terminal 22 of each of the function switching switches K11-K1 is connected to the trigger signal derivation terminal 401 through the diodes D3-D6, which can avoid different control interfaces S21-S2 / electric detonation function modules from affecting each other. In this way, the function switching switches of the corresponding simulation function units 310-340 are in the second state, and multiple control interfaces S21-S24 / electric detonation function modules can be trained separately, thereby improving the adaptability of the simulation explosion training device and increasing the number of training items. For example, the function switching switch K11 can be in the second state, the power supply access terminal 10 is connected to the second power supply output terminal 12, the signal access terminal 20 is connected to the second signal output terminal 22, and the control interface S21 / electric detonation function module is in the power-on state, ready for simulation explosion training. At the same time, the function switching switch K11 is in the III state (the third state), the power supply input terminal 10 is kept separate from the first power supply output terminal 11 and the second power supply output terminal 12; the signal input terminal 20 is kept separate from the first signal output terminal 21 and the second signal output terminal 22, and the control interface S21 / electric detonation function module is in the power-off state.

[0061] Similarly, any one, any two or any three of the function switching switches K11-K14 can be powered on, thereby providing a prerequisite for conducting corresponding training.

[0062] When the function switching switch K11 is in the first state (I state), its working principle can refer to Figure 1 Description of the illustrated embodiment.

[0063] Please refer to Figure 4 This figure is a schematic diagram of the circuit principle of a remote-controlled multi-channel explosion simulation training device in another embodiment. Figure 3 Compared with the embodiment shown in the figure, in this embodiment, each of the analog function units 310-340 control relays J1-J4 also includes a holding normally open circuit Ki1-Ki4 that cooperates with the coil circuit. The two ends of the holding normally open circuit Ki1-Ki4 are electrically connected to the input end of the coil circuit and the first power output end 11 of the corresponding function switching switch K11-K12, respectively. In this way, the magnetic force generated on the coil circuit can change the state of the series normally open circuit Kj1-Kj4 and the holding normally open circuit Ki1-Ki4, so that the normally open contacts of the two are switched to a closed state.

[0064] Since the retentive normally open circuit Ki1-Ki4 is set, after the corresponding control interface S21-S24 cooperates with the electric detonation function module to be triggered, the coil circuit is powered on to close the contacts of the retentive normally open circuit Ki1-Ki4; since the two ends of the retentive normally open circuit Ki1-Ki4 are respectively electrically connected to the input end of the coil circuit and the first power output end 11 of the corresponding function switching switch K11-K12, the corresponding coil circuit can be kept connected, that is, the electrical path state is maintained, and the series circuits of the corresponding function switching switches K11-K12 are kept connected, which can better determine the training process, thereby improving the training effect, and facilitating the management of simulated explosion training and training assessment.

[0065] The specific scenario is: each function switching switch K11 is in the first state (I state), the simulation function units 310-340 are in the "AND" state, and the electric detonation function modules that cooperate with the four control interfaces S21-S24 are triggered to successfully send the detonation signal to the explosion simulator 300. Since the first power output terminal 11 and the control relays J1-J4 of the four function switching switches K11 are all powered on, an electric loop is formed between the power supply unit 100, the power access terminal 10, the first power output terminal 11, the corresponding coil circuit and the ground wire, so that the series circuit of the corresponding holding normally open circuit Ki1-Ki4 remains connected. At this time, even if any electric detonation function module that cooperates with the control interface (such as the control interface S22) no longer outputs the detonation signal, the corresponding holding normally open circuit (such as Ki2) still maintains the passage, and the four simulation function units 310-34 can also maintain the "AND" state. At this time, not only can other electric blasting function modules be powered on normally and corresponding training can be carried out, thereby increasing the training items; at the same time, as long as the corresponding electric blasting function module (such as the electric blasting function module cooperating with the control interface S22) is triggered, the corresponding retentive normally open circuit (such as Ki2) will remain connected. Then, according to the state of the retentive normally open circuit Ki2, it can be determined whether the corresponding electric blasting function module has been triggered, and then the training process can be tracked, which is convenient for training assessment and supervision.

[0066] It can be understood that when the function switching 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 remain disconnected; the signal input terminal 20, the first signal output terminal 21 and the second signal output terminal 22 remain disconnected, so that each part can lose power, thereby resetting the function switching switches K11-K14 and the control relays J1-J4.

[0067] like Figure 4As shown, in this embodiment, each of the analog function units 310-340 also includes a power-on indication device, one end of which is electrically connected to the power input end of the control interface S21-S24, and the other end is grounded. In this way, when the power pin of the control interface S21-S24 is powered on, the power-on indication device displays. Similarly, each of the analog function units 310-340 also includes a trigger indication device, one end of which is electrically connected to the signal output end of the control interface S21-S24, and the other end is grounded; in this way, when the corresponding electric detonation function module is triggered and the electrical signal output pin outputs the detonation signal, the trigger indication device can indicate the trigger state. It can be understood that the power-on indication device and the trigger indication device can be light-emitting diodes D11 and D12. In this embodiment, the anode D11 of the diode for power-on indication is electrically connected to the power input terminal, the anode D12 of the diode for power-off 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 mutual influence between the power-on indication circuit and the power-off indication circuit.

[0068] like Figure 5 As shown, Figure 5 for Figure 4 The schematic diagram of the layout of the remote-controlled multi-channel simulated explosion training device is shown, and the remote-controlled multi-channel simulated explosion training device may include a closed box body 400, in which the power supply unit 100 and the simulated function units 310-340 are enclosed, and the explosion simulator 200 is located outside the box body. The box body can be packaged using existing packaging processes to ensure the reliability of the connection of electronic components in the box body, while preventing others from arbitrarily changing the circuits and components in the box body.
