As shown in fig. 1, 2, 3, 4 and 5, the pins 1 and 2 of the power input end of the K1 of the AC-DC power supply are connected with the two poles of the AC 220V power supply respectively through wires, the pin 3 of the power output end of the AC-DC power supply K1 is connected with the power input end of the power switch SK through wires, the power output end of the power switch SK, the pin 4 of the AC-DC power supply K1 and the pins 1 and 2 of the power input end of the time control switch K3 are connected with the pins 1 and 2 of the power input end of the photoelectric switch K respectively through wires.

As shown in fig. 1, 2, 3, 4 and 5, after the AC-DC power supply K1 is powered on, the 3 and 4 pins output DC power to the power input end of the power switch SK, and after the AC-DC power supply AK7 is powered on, the 3 and 4 pins output DC power to the power input ends of the plurality of wireless receiving mechanisms K8. When no person takes the elevator, the bottom plate 1 is not stressed, the lower end of the bottom plate 1 is not contacted with the upper end of the power switch SK button, the contacts in the power switch SK are not closed, and the control mechanism and the photoelectric switch K cannot work electrically. When a person takes the elevator, gravity acts on the bottom plate 1, the bottom plate compresses the spring 33 along the guide rod 32 to move downwards, so that the button of the power switch SK is pressed to close the internal contact, and the control mechanism and the photoelectric switch K work electrically. After the control mechanism is electrified to work, pins 3 and 4 of the two sets of time control switches K3 and K4 circularly output 6 seconds of power to positive and negative positive electrode power input ends of the motor reduction device DJ, and the motor reduction device DJ is electrified to drive the photoelectric switch K to rotate clockwise and anticlockwise; when the rotation shaft drives the limiting plate 43 and the photoelectric switch K to rotate to the rear side of the right end and the left end and the rear left part and the right part in the car 5 respectively and are parallel, the right end and the left end of the limiting plate 43 are respectively contacted with the buttons of the right end and the left end power switches AS1 and S2, the internal contacts of the power switches AS1 and S2 are opened, and AS the two power input ends of the two power switches AS1 and S2 are connected in series between the 3 pin of the time control switch K3, the 4 pin of the time control switch K4 and the positive and negative electrode power input ends of the motor speed reducer DJ through wires, the photoelectric switch K rotates to be parallel to the rear right end and the left end of the car (after about 5 seconds, the right end and the left end of the car can be rotated), the motor speed reducer DJ loses electricity, and only the motor speed reducer DJ reversely inputs power, so that the motor speed reducer DJ does not work, and adverse effects on normal use caused by uncontrolled movement of the motor speed reducer DJ to one side are prevented.

As shown in fig. 1, 2, 3, 4 and 5, when the photoelectric switch K rotates clockwise and anticlockwise, the infrared beam emitted from the front end probe of the photoelectric switch K irradiates the personnel in the elevator through the opening straight line, when the personnel is in the elevator (the height is higher than 1.1 m), the front of the probe of the photoelectric switch K has an obstacle to block the 3 feet of the probe and cannot output power, when the personnel is in the elevator but falls down for various reasons, the front of the probe of the photoelectric switch K has no obstacle to block the 3 feet of the probe of the photoelectric switch K from outputting power, so the time relay module K5 works electrically, and the time relay module K5 performs time counting. In actual condition, when personnel in the elevator normally stand, the 3 feet of the photoelectric switch K can stop outputting power supply within 12 seconds, the time relay module K5 can stop supplying power within 12 seconds, and the time timing can be performed again only when the power is obtained next time, so that as long as the personnel in the elevator are in a standing state, the accumulated timing of the time relay module K5 can not reach a set value, and the 3 feet and the 4 feet of the elevator can not output power supply. When one person in the elevator is in an inverted state, after the accumulated time of the time relay module K5 reaches a set value (for example, 13 seconds), the 3-pin and 4-pin output power sources of the time relay module K enter the power source input end of the wireless transmitting mechanism K6, and the wireless transmitting mechanism K6 transmits a first path of wireless signals or two paths, three paths, four paths, five paths, six paths, seven paths and eight paths of wireless signals (two contacts under the wireless transmitting keys T1, T2, T3, T4, T5, T6, T7 and T8 of the eight sets of wireless transmitting mechanism K6 are connected together in advance). In the range of 3000 m, after the wireless receiving mechanism K8 receives signals, 3 or 4, 5, 6, 7, 8, 9 and 10 feet of the wireless receiving mechanism K8 output power sources to the positive power source input ends of eight sets of audible and visual alarms R respectively, so that the corresponding audible and visual alarms R give out electricity, and personnel in a material pipe room can timely rescue people falling to the ground according to the text prompt positions corresponding to the audible and visual signals sent by the corresponding audible and visual alarms R. Through the above, when no person takes the elevator, the equipment is in a power saving state, and when the person takes the elevator, the detection mechanism and the trigger mechanism can work electrically, so that the purpose of automatic control is realized; when someone does not fall to the ground in the elevator, the wireless transmitting mechanism does not transmit wireless signals, when someone falls to the ground in the elevator, the wireless transmitting mechanism transmits wireless signals, and the corresponding audible and visual alarm can be powered to transmit audible and visual signals to prompt indoor operators on duty of the object pipe, so that the object pipe operators can rescue the falling people in time according to the area where the operators fall on site, the probability that the passengers taking the elevator get more serious results due to too late rescue after falling to the falling is reduced, and powerful technical support is provided for the safe transportation of the elevator to the residents to go upstairs and downstairs.
