When the angle is proper, the attendant presses the fourth transmitting button S4 of the wireless transmitting circuit module a4 again, so that the wireless transmitting circuit module a4 transmits a fourth wireless open-circuit signal, the wireless receiving circuit module A3 stops outputting a high level after receiving the fourth open-circuit signal by 7 feet, and the motor speed reducing mechanism M no longer drives the camera SP to rotate and stop at the position required by the attendant.

In practical situations, if more cameras need to be controlled, more corresponding wireless remote control devices and monitoring camera control devices are adopted.

As shown in fig. 2 and 4, after the 220V ac power enters pins 1 and 2 of regulated power supply a9, pins 3 and 4 of regulated power supply a9 will output stable 12V dc power into the two terminals of the power input of time-controlled switch a5 under the action of its internal circuit, so that time-controlled switch a5 is in power-on operation. The 3 and 4 feet of the time control switch A5 can be set by the internal circuit and the technical staff (including duty entrance guard, family of the old, etc.), the required time period (for example, 12 o 'clock in evening to 5 o' clock in the next morning, different users can set according to their living habits, for example, the old can sleep only at 11 o 'clock in morning, and get up at 6 o' clock in the next morning, so the set time is the output power between 11 o 'clock in evening and 6 o' clock in the next morning every day) to enter the two ends of the power input of the detection circuit and the timing emission circuit, so the circuit can be powered to work between 12 o 'clock in evening and 5 o' clock in the next morning. In the detection circuit, when the old closes the window before sleeping at night, the distance between the movable window sash and the front end of the detection head of the photoelectric switch A6 is less than 50cm, and 3 feet of the photoelectric switch A6 do not output high level; when the old forgets to close the window before sleeping at night, the distance between the movable window sash and the front end of the detecting head of the photoelectric switch A6 is larger than 50cm (infrared beams emitted by the emitting head of the photoelectric switch A6 directly irradiate outdoors), the 3-pin output high level of the photoelectric switch A6 is subjected to voltage reduction and current limiting through the resistor R11 and enters the base of the NPN triode Q5, the NPN triode Q5 is conducted, the collector is conducted, and the low level is output, so that conditions are created for the work of a rear-stage circuit. After 12 o' clock at night, the old does not turn on the indoor lamp, the light receiving surface of the photoresistor RL (considering the influence of the curtain at home on the light, the photoresistor RL can be independently installed in a small box, and the small box is installed in the indoor area which cannot be shielded by the curtain) has no large illumination resistance value of about 10M, the base voltage of an NPN triode Q5 is lower than 0.7V, and the rear-stage circuit does not work. After 12 o' clock at night, the old opens the indoor lamp, the light receiving surface of the photoresistor RL is smaller in illumination resistance value by about 100K, the 12V power supply is subjected to voltage reduction and current limiting through the resistor R11 and enters the NPN triode Q5, the base voltage is higher than 0.7V, the NPN triode Q5 is conducted, the collector is conducted, the low level is output, and conditions are created for the work of a rear-stage circuit.

As shown in fig. 2 and 4, in the timing transmitting circuit, when the old is not closed or turned on between 12 pm and 5 am in application, after the NPN triode Q5 turns on and outputs a low level to the cathode of the electrolytic capacitor C, the 12V power supply charges the electrolytic capacitor C through the resistor R5 within 30 minutes from the beginning (the time period mainly considers the requirements of normal night, old people on light-on time, the light is not turned off in the late night of 30 minutes, the old people possibly get up at night, the old people fall down in a bathroom and the like and do not return to a bedroom, a later stage circuit alarms to prevent false alarm), when the electrolytic capacitor C is not fully charged, the voltage of the base electrode of the power supply, which enters the NPN triode Q6 after the anode of the power supply is subjected to voltage reduction and current limitation through the resistors R5 and R6, is lower than 0.7V, the base electrode voltage of the NPN triode Q6 is too low and is in a cut-off state, then the relay K5 cannot be electrified and attracted, and the wireless transmitting circuit module A7 cannot transmit a wireless signal. After about 30 minutes (time is 1.1 resistance of the resistor R5 and capacitance of the electrolytic capacitor C), when the electrolytic capacitor C is fully charged, the positive electrode of the power supply is subjected to voltage reduction and current limitation by the resistors R5 and R6 and then enters the base voltage of the NPN triode Q6 to be higher than 0.7V, the NPN triode Q6 is in a conducting state, the collector outputs low level and enters the negative power supply input end of the relay K5, and then the relay K5 is electrified to attract the power supply input end and the normally-open contact end to be closed. Because the normally open contact end of the relay K5 is connected with the positive power input end of the wireless transmitting circuit module A7, and the lower contact of the first wireless key S1 of the wireless transmitting circuit module A7 is connected with the lead in advance, the wireless transmitting circuit module A7 can transmit a first path of wireless closing signals at the moment (the lower contacts of the second, third and fourth wireless keys S2, S3 and S4 of the wireless transmitting circuit module A7 in the second, third and fourth old people families are connected with each other in advance respectively, so that the second, third and fourth paths of wireless closing signals can be transmitted respectively). After the indoor light is turned on or the window is closed, the wireless transmitting circuit module A7 does not send a wireless closing signal any more because the NPN triode Q5 is cut off.

As shown in fig. 1 and 5, after the 220V ac power enters pins 1 and 2 of the regulated power supply A8, pins 3 and 4 of the regulated power supply A8 output stable 12V dc power into the two terminals of the power input of the wireless receiving circuit module a10 under the action of its internal circuits, so that the wireless receiving circuit module a10 is in a power-on operating state. When the wireless transmitting circuit module a7 mainly monitors the old's home to transmit the first, second, third and fourth wireless closed signals, respectively, after the wireless receiving circuit module a10 receives the wireless signals, its 4, 5, 6 and 7 pins will output high level respectively, via the resistors R7, R8, R9 and R10, the high level is reduced voltage and limited current to enter the positive power input terminals of the light emitting diodes VL, VL1, VL2 and VL3, so that the light emitting diodes VL, VL1, VL2 and VL3 emit light respectively to indicate which old's home has forgotten to close the window or has an accident. After watching different diodes to emit light (an element box at the side end of each diode can be printed with characters, for example, 219 and 901 represent 2 units of 1 unit, 9 buildings and 901 indoor old people need rescue), a person on duty can timely arrive at the scene to check the situation or save the life (in practical situations, situations that two or more old people need rescue at the same time rarely occur, the requirement of the working principle of the embodiment is mainly explained in the present invention), and unforeseen serious consequences caused by the rescue too late are prevented (the window closing is not prompted, the window closing is prevented, the theft is prevented, and the like). In this novel, daily life monitoring device 3, wireless receiving device 4 can adopt many sets, monitor more old man's daily life etc. and reach the wider control purpose of scope. In the circuit, the resistances R, R1, R2, R3, R5, R6, R11, R7, R8, R9 and R10 are respectively 1K, 3.48M, 470K, 100K, 1.8K and 1.8K. The model numbers of the NPN triodes Q, Q1, Q2, Q3, Q4, Q5 and Q6 are 9013. The light emitting diodes VL, VL1, VL2, VL3 are red light emitting diodes. The photoresistor RL is model MD 45.
