As shown in fig. 3, two

ends

1 and 2 of the power input of the switching power supply U1 and two ends of the 220V ac power supply are respectively connected by leads, two ends 3 and 4 of the power output of the switching power supply U1 and two ends VCC and GND (1 and 2 pins) of the power input of the human body infrared sensing module U2, the positive power input end of the relay K1 at the two ends of the power input of the control circuit and the emitter of the NPN triode Q1 are respectively connected by leads, the pin 3 of the signal output end of the human body infrared sensing module U2 and the other end of the resistor R1 at the signal input end of the control circuit are connected by leads, the normally open contact end of the relay K1 at the first path of the power output end of the control circuit and the emitter of the NPN triode Q1 and the two ends of the power input of the electromagnetic pull rod DC are respectively connected by leads, the normally open contact end of a second power output end relay K2 of the control circuit and the emitting electrode of an NPN triode Q1 are respectively connected with the two ends of the power input of the motor reducing mechanism M through leads.

As shown in fig. 1, 2 and 3, before the human-shaped target body 1 is used, the lower end of the human-shaped target body 1 is inserted into the rectangular groove 9, and then the two manual screws 91 are respectively screwed tightly, so that the human-shaped target body 1 is firmly fixed in the rectangular groove 9. The Fresnel lens can be placed at any indoor position according to requirements, in order to achieve the effect of suddenly covering hidden objects on the front end cover of the shell 2 (the front end of the Fresnel lens 61 of the human body infrared sensing module 6 cannot be shielded, a detection head of the human body infrared sensing module 6 inclines by about 10 degrees towards the front upper end, the front end of the Fresnel lens 61 also inclines by a certain angle towards the front upper end, and the Fresnel lens can effectively detect the human body moving by about 7 meters within the range of 120 degrees around the front end of the Fresnel lens 61), and can achieve a good training effect when being used indoors. The humanoid target body 1 lies on the ground in the initial state before the excitation. After the 220V ac power supply enters the

pins

1 and 2 of the switching power supply U1, the switching power supply U1 outputs a stable 12V dc power supply to the control circuit and the power input end of the human body infrared sensing module U2 under the action of its internal circuit, so that the control circuit and the human body infrared sensing module are in an energized operating state.

As shown in fig. 1, 2 and 3, in an actual training, when a training person enters a range of about 7 meters near the indoor human body infrared sensing module U2, a probe of the human body infrared sensing module U2 detects a moving human body under the combined action of the fresnel lens, and then the human body infrared sensing module U2 outputs a high level at its 3 pin under the action of an internal circuit, the high level is reduced in voltage and limited in current (higher than 0.7V) by the resistor R1 and enters the base of the NPN triode Q1, so that the NPN triode Q1 turns on its collector to output a low level and enters the negative power input end of the relay K1; because the positive power input end and the control power input end of the relay K1 are communicated with the 3 pins of the switch power supply U1, the normally open contact end of the relay K1 is connected with the positive power input end of the electromagnetic pull rod DC, and the negative power input end of the electromagnetic pull rod is connected with the 4 pins of the switch power supply U1, the relay K1 can be electrified to close the control power input end and the normally open contact end, and open the normally closed contact end and the control power input end, so that the electromagnetic pull rod DC is electrified to work, and the armature rod of the electromagnetic pull rod DC moves leftwards by about 1cm under the action of an electromagnetic mechanism and the like in the electromagnetic pull rod DC after being electrified to work. Before power is not supplied, the front right end of the armature rod 71 of the electromagnetic pull rod DC is positioned in one of the circular through holes 151 of the driving plate 15 by about 4mm, and when the electromagnetic pull rod DC is powered to work and the armature rod 71 moves leftwards, the front right end of the armature rod 71 of the electromagnetic pull rod DC is separated from one of the circular through holes 151 of the driving plate 15; because the active plate 15 and the armature rod 71 are separated, the connecting plate 14 and the shaft rod 12 can rotate clockwise and anticlockwise forward under the elastic action force of the multi-coil spring 4, and drive the humanoid target 1 to rotate anticlockwise and immediately turn from the horizontal state to the vertical state on the ground, two convex rectangular limit blocks 102 at the left and right parts of the front end of the humanoid target 1 just contact with the left and right parts of the front inner side of the shell 3, so that the humanoid target 1 is ensured to be in the vertical state, and the training effect of the training personnel on the abruptness is achieved (the lead connected with the electromagnetic pull rod 7 has a certain length allowance, and the lead is ensured not to be strained and damaged when the lead rotates along with the connecting plate 14). When the trainee leaves the detection range of the detection head of the infrared induction module U2, the 3 feet of the infrared induction module U2 stops outputting high level, so that the NPN triode Q1 stops outputting low level when the collector is cut off, the relay K1 is powered off and does not attract the control power supply input end and the normally closed contact end to be closed, the control power supply input end and the normally open contact end to be opened, thus, when the armature rod 71 of the electromagnetic pull rod DC loses power and returns to the initial position rightwards under the action of the internal spring mechanism and the like, the right end of the armature rod 71 enters one of the circular through holes 151 of the driving plate 15 again by about 4mm (even if the right part of the armature rod 71 does not enter the circular through hole at the moment, and the subsequent driving plate 15 is driven by the power output shaft of the motor speed reducing mechanism M to rotate clockwise, the armature rod 71 of the electromagnetic pull rod inevitably enters one of the circular through holes 151 of the driving plate due to the fact that the circular through holes 151 of the driving plate are consistent with the circumferential position of the armature rod 71 of the electromagnetic pull rod). Because the positive power input end and the control power input end of the relay K2 are connected with the normally closed contact end of the relay K1, when a person leaves the detection range of the detection head of the infrared induction module U2 and the relay K1 loses power and does not attract the control power input end and the normally closed contact end to be closed (the positive power input end and the control power input end of the relay K1 are communicated with the 3 pins of the switch power U1), the positive pole of the 12V power supply enters the control power input end and the positive power input end of the relay K2 (the negative power input end of the relay K2 is communicated with the 4 pins of the switch power U1), and the relay K2 is electrified to attract the control power input end and the normally open contact end to be communicated; because the positive power supply input end of the motor speed reducing mechanism M is connected with the normally open contact end of the relay K2 (the negative power supply input end of the motor speed reducing mechanism M is communicated with the 4 pins of the switching power supply U1), the motor speed reducing mechanism M can be electrified to work after a person leaves the detection range of the detection head of the infrared induction module U2; after the motor reducing mechanism M works by electricity, the motor rotating shaft rotates anticlockwise, after the multi-stage reducing gears in the shell at the left end reduce speed and increase torque, the power output shaft of the motor reducing mechanism M rotates clockwise and drives the shaft rod 12 to rotate clockwise through the driving plate 15, the armature rod 71 of the electromagnetic pull rod and the connecting plate 14, the spring 4 can be wound and tightened in the clockwise rotation of the shaft rod 12 to enable the shaft rod 12 to have anticlockwise rotation potential energy, and preparation is made for people to approach the infrared induction module U2 next time and jump the humanoid target body 1. When the humanoid target 1 is parallel to the ground again, the permanent magnet 17 is just contacted with the upper end of the plastic box 19 at the moment, and the movable contact and the static contact inside the reed switch GH are opened; because, two wiring terminals of tongue-and-wire duct GH are established ties between second relay K2 positive power input end and control power input end and first relay K1 normally closed power output end, so at this moment, relay K2 can lose the electricity and no longer pick up its control power input end and normally open contact end and open a way, and then motor reduction mechanism M can lose the electricity and no longer work, prevent that motor reduction mechanism M from driving humanoid target body 1 clockwise rotation too much, and lead to the whole work of equipment to receive the influence. Because the electromagnetic brake mechanism is arranged in the motor reducing mechanism M, after the electromagnetic brake block (connected with two wires of the motor in parallel) loses power, the brake disc installed together with the motor rotating shaft can be firmly braked by the brake block of the electromagnetic brake block, and after the motor reducing mechanism M stops rotating, the anticlockwise elastic acting force of the spring 4 can cause the human-shaped target 1 to move upwards anticlockwise and prevent the rotating shaft of the motor reducing mechanism M from rotating. The human-shaped target body 1 can achieve better abruptness when excited, after each excitation, as long as a training person leaves a monitoring range, the human-shaped target body can recover the initial position under the action of a related mechanism, the next training person can conveniently enter a room to be excited, the reset operation of a special person is not needed, the manual expenditure is reduced, the human-shaped target body is particularly suitable for the same subject training under the condition that a plurality of training persons exist, and a good training effect can be achieved. In the invention, the relays K1 and K2 are DC4123 type 12V relays of Songle brand; the model of the NPN triode Q1 is 9013; the resistance R1 is 470K; the reed switch GH is a high-power plastic-sealed normally closed contact reed switch with a brand BASEUS/double-Si model GPS-11B.
