After the 220V ac power supply enters the two power input terminals of the switching power supply a (a9), the

pins

When a thief enters the monitoring range of the middle part under the camera in motion, at the moment, because the finished product A2 of the pyroelectric infrared detection switch module can detect the infrared signal of a moving human body, 3 pins of the finished product can output high level to enter the positive power input end of the relay K1 under the action of the internal circuit of the finished product, and then the relay K1 is electrically attracted to close the control contact end and the normally open contact end (the finished products A1 and A3 of the pyroelectric infrared detection switch module cannot output high level because 3 pins of the infrared signal of the human body cannot be detected, and the relay K, K2 is in a power-off state). When a thief enters the lower right monitoring range of the camera in a moving mode, at the moment, because the finished product A3 of the pyroelectric infrared detection switch module can detect infrared signals of a moving human body, 3 pins of the finished product can output high level to enter the positive power input end of the relay K2 under the action of the internal circuit of the finished product, and then the relay K2 is electrified to attract the control contact end and the normally open contact end of the relay to be closed (the finished products A1 and A2 of the pyroelectric infrared detection switch module cannot output high level because 3 pins of the infrared signals of the human body cannot be detected, and the relay K, K1 is in a power-off state). Because the control contact end, the normally open contact end and the wireless transmitting circuit module finished product A4 of the relays K, K1 and K2 are respectively connected with two contacts under each key of the three wireless signal transmitting keys S1, S2 and S3 through wires, when a thief enters the front left end, the middle part and the right part of the camera respectively, the two contacts under each key of the three wireless signal transmitting keys S1, S2 and S3 are respectively closed, and further, under the action of an internal circuit of the wireless transmitting circuit module finished product A4, the wireless transmitting circuit module finished product A4 can respectively send three different wireless closing signals.

As shown in fig. 1, 2, and 3, when the wireless transmitting circuit module finished product a4 sends a first path of wireless closing signal, that is, when a thief is located at the left end of the camera monitoring area, after the wireless receiving circuit module a5 receives the signal (the wireless signal receiving distance can reach about 300 meters), its 4 pins will output a high level, which is reduced by the resistor R and limited by current, and enter the base of the NPN triode Q1, so that the NPN triode Q1 turns on its collector to output a low level, which enters the negative power input end of the relay K3, the relay K3 is powered to pull in its control power input end and normally open contact end to be closed, and further, the time control switch a6 is powered to operate; under the action of an internal circuit of the time control switch A6 and the time of the power supply output by the

pins

3 and 4 set by a technician, the

pins

3 and 4 can firstly output 9 seconds of power supply to enter the two ends of the power supply input end of the relay K4 and then stop outputting the power supply, so that within the time of 9 seconds, the relay K4 is electrified to attract the two control power supply input ends and the two normally open contact ends of the relay K4 to be respectively closed, and the two control power supply input ends and the two normally closed contact ends are respectively opened; because two normally open contact ends of the relay K4 are respectively connected with the positive and negative pole power input ends of the motor reducing mechanism M, the motor reducing mechanism M can be used as a power output shaft of the motor reducing mechanism M to drive the camera to rotate towards the left side end within 9 seconds, after 9 seconds, the

pins

3 and 4 of the time control switch A6 stop outputting power, and the two control power input ends and the two normally closed contact ends of the relay K4 are respectively closed; because two normally closed contact ends of the relay K4 are respectively connected with the negative and positive power supply input ends of the motor speed reducing mechanism M, after 9 seconds, the motor speed reducing mechanism M can be used as a power output shaft of the motor speed reducing mechanism M to drive the camera to rotate towards the right side end; in practical situations, when the motor reduction mechanism M drives the camera and the magnet CT to move left or right, the magnet CT passes through the upper ends of the reed pipes GH, GH1, and GH2, respectively, and when the magnet is located at the upper end of the reed pipe GH (i.e. when the camera moves left in place), the magnetic acting force of the magnet acts on the reed pipe GH, so that the internal contact of the reed pipe GH is open, and thus, the positive power supply at the pin 1 of the time control switch a6 does not enter the positive control power supply input end of the relay K4, that is, because the positive control power supply input end of the relay K4 does not have power supply input, the relay K4 cannot cause the motor reduction mechanism M to work when power is on and off, and no longer drives the camera to rotate, so that the camera can automatically rotate to the left part of the motor reduction mechanism M to monitor and automatically stop rotating after being in place when the camera is stolen, the video monitoring needs of the left end area are met (a manufacturer or a user adjusts the position of a left end reed switch GH arranged on the supporting plate, and the camera can stop moving after moving to any needed position from the left end).

As shown in fig. 1, 2, and 3, when the wireless transmitting circuit module finished product a4 sends a third wireless close signal, that is, when a thief is located at the right end of the camera monitoring area, after the wireless receiving circuit module a5 receives the third wireless close signal (the wireless signal receiving distance can reach about 300 meters), its 6 pins will output a high level, via the resistor R3, reduce the voltage and limit the current, and enter the base of the NPN triode Q3, so that the NPN triode Q3 turns on its collector to output a low level, and enters the negative power input end of the relay K7, the relay K7 gets electricity to attract the control power input end and the normally open contact end thereof to be closed, and further, the time control switch A8 gets electricity to work; under the action of an internal circuit of the time control switch A8 and the time of the power supply output by the

pins

3 and 4 set by a technician, the

pins

3 and 4 can firstly output 9 seconds of power supply to enter the two ends of the power supply input end of the relay K8 and then stop outputting the power supply, so that within the time of 9 seconds, the relay K8 is electrified to attract the two control power supply input ends and the two normally open contact ends of the relay K8 to be respectively closed, and the two control power supply input ends and the two normally closed contact ends are respectively opened; because two normally open contact ends of the relay K8 are respectively connected with the positive and negative pole power input ends of the motor reducing mechanism M, the motor reducing mechanism M can be used as a power output shaft of the motor reducing mechanism M to drive the camera to rotate towards the left side end within 9 seconds, after 9 seconds, the

pins

3 and 4 of the time control switch A8 stop outputting power, and the two control power input ends and the two normally closed contact ends of the relay K8 are respectively closed; because two normally closed contact ends of the relay K8 are respectively connected with the negative and positive power supply input ends of the motor speed reducing mechanism M, after 9 seconds, the motor speed reducing mechanism M can be used as a power output shaft of the motor speed reducing mechanism M to drive the camera to rotate towards the right side end; in practical situations, when the motor speed reducing mechanism M drives the camera and the magnet CT to move left or right, the magnet CT passes through the upper ends of the reed pipes GH, GH1 and GH2, respectively, when the magnet is located at the upper end of the reed pipe GH2 (i.e. when the camera moves right in place), the magnetic acting force of the magnet CT acts on the reed pipe GH2, so that the internal contact of the reed pipe GH2 is open, thus, the positive power supply at the 1-pin position of the time control switch a8 cannot enter the positive control power supply input end of the relay K8, that is, because the positive control power supply input end of the relay K8 has no power supply input, the relay K8 cannot cause the motor speed reducing mechanism M to work when power is on and on or off, the camera is no longer driven to rotate, and when the camera has a thief at the right side end of a detection area, the right part of the camera can be automatically rotated to monitor and take a picture, and the camera stops rotating automatically after being in place, the video monitoring needs of the right end area are met (a manufacturer or a user adjusts the position of a reed switch GH2 at the right end arranged on the supporting plate, and the camera can move to the right end and stop moving after moving to any needed position).

As shown in fig. 1, 2, and 3, when the wireless transmitting circuit module finished product a4 sends a second wireless close signal, that is, when a thief is located in the middle of the camera monitoring area, after the wireless receiving circuit module a5 receives the second wireless close signal (the wireless signal receiving distance can reach about 300 meters), its 5 th pin outputs a high level, and the high level is reduced voltage and limited current by the resistor R1 to enter the base of the NPN triode Q2, so that the NPN triode Q2 turns on its collector to output a low level to enter the negative power input end of the relay K5, the relay K5 is powered to pull in its control power input end and normally open contact end to be closed, and further, the time control switch a7 is powered to operate; under the action of an internal circuit of the time control switch A7 and the time of the power supply output by the

pins

3 and 4 set by a technician, the

pins

3 and 4 can firstly output 9 seconds of power supply to enter the two ends of the power supply input end of the relay K6 and then stop outputting the power supply, so that within the time of 9 seconds, the relay K6 is electrified to attract the two control power supply input ends and the two normally open contact ends of the relay K6 to be respectively closed, and the two control power supply input ends and the two normally closed contact ends are respectively opened; because two normally open contact ends of the relay K6 are respectively connected with the positive and negative pole power input ends of the motor reducing mechanism M, the motor reducing mechanism M can be used as a power output shaft of the motor reducing mechanism M to drive the camera to rotate towards the left side end within 9 seconds, after 9 seconds, the

pins

3 and 4 of the time control switch A7 stop outputting power, and the two control power input ends and the two normally closed contact ends of the relay K6 are respectively closed; because two normally closed contact ends of the relay K6 are respectively connected with the negative and positive power supply input ends of the motor speed reducing mechanism M, after 9 seconds, the motor speed reducing mechanism M can be used as a power output shaft of the motor speed reducing mechanism M to drive the camera to rotate towards the right side end; in practical situations, when the motor speed reducing mechanism M drives the camera and the magnet CT to move left or right, the magnet CT passes through the upper ends of the reed pipes GH, GH1, GH2, respectively, and when the magnet is located at the upper end of the reed pipe GH1 (i.e. when the camera moves to the middle in place), the magnetic acting force of the magnet CT acts on the reed pipe GH1, so that the internal contact of the reed pipe GH1 is open, thus, the positive power supply at pin 1 of the time control switch a7 cannot enter the positive control power supply input end of the relay K6, that is, because the positive control power supply input end of the relay K6 has no power supply input, the relay K6 cannot be powered on and powered off to stop the motor speed reducing mechanism M, and no longer drives the camera to rotate, so that when the camera has a thief in the middle of a detection area, the middle of the motor speed reducing mechanism M can be automatically rotated to monitor and stop rotating after being in place, the video monitoring requirement on the middle area of the front end of the camera is met (a manufacturer or a user adjusts the position of a middle reed switch GH1 arranged on a supporting plate, so that the camera can move to the middle part to any required position and then stops moving). Through the circuit function, when a thief enters three different directions of a monitoring area in use, the corresponding pyroelectric infrared detection switch module in the corresponding area can enable a wireless transmitting circuit module finished product to transmit a corresponding path of wireless closing signal after the detection is carried out by the pyroelectric infrared detection switch module; after the wireless receiving circuit module located near the camera receives the corresponding wireless closed signal, the control mechanism can automatically control the motor reducing mechanism to rotate by a certain angle, the front end of the camera is aligned to an area where thieves move as far as possible, and a better video signal acquisition effect can be obtained, so that technical support is provided for the security equipment to play a greater role (a better field video data can be obtained in a monitoring area).
