Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following will describe the dual sensor attached automatic elevator disinfection device and disinfection method in further detail with reference to the attached drawings.

As shown in fig. 1-2, the automatic disinfection device for the double-inductor additional type elevator comprises a control system, and a switching power supply, a door lintel inductor, a top inductor, an ultraviolet lamp and an emergency button which are connected with the control system. The control system consists of a singlechip, a solid-state relay and a voltage stabilizing circuit and realizes the disinfection of the ultraviolet lamp and the control of the disinfection time. The singlechip can adopt a 51 singlechip, and also can adopt an STM32 singlechip. The door lintel sensor and the top sensor adopt non-contact infrared heat release human body sensors. The ultraviolet lamp adopts a short-wave ozone-free straight tube type or an H-tube type, and the ultraviolet lamp tube adopts a quartz glass lamp tube. The lamp shade is arranged outside the ultraviolet lamp, the power of the ultraviolet lamp is configured according to the size of the actual space of the elevator car, and the control system is fixedly arranged inside the lamp shade. The lintel inductor is arranged at the lintel position right above the elevator door and used for inducing elevator passengers outside the elevator, the top inductor is arranged at the top of the elevator car and used for inducing elevator passengers inside the elevator, when the lintel inductor or the top inductor induces a human body, the induced data are transmitted to the control system, the ultraviolet lamp stops disinfection by the control system identification signal, and when the lintel inductor and the top inductor do not induce the human body, the ultraviolet lamp starts disinfection. The emergency button is connected with the control system and used for cutting off the ultraviolet lamp circuit when the elevator fails or the inductor fails. A fuse is arranged between the emergency button and the elevator additional power supply, and when the circuit of the disinfection device is overloaded, the fuse is disconnected to play a role in protecting personnel. Further, in order to prevent the ultraviolet light source from directly irradiating the outside of the elevator door to protect the safety of the elevator passengers, the ultraviolet lamp is arranged on the elevator wall right above the same side of the elevator door. The emergency button is arranged on the elevator wall at the same side of the elevator door, and the emergency button does not conflict with the original elevator equipment (such as a floor button and the like). Meanwhile, the installation height of the emergency button is within the range of 1.4m-1.7m away from the bottom of the elevator car (too low and too high are not suitable for preventing children from mistakenly pressing and people from normally touching). The attention of the ultraviolet disinfection device is needed near the emergency button, and the emergency button is prompted by an obvious prompt. Furthermore, the door lintel inductor is installed on the elevator door lintel through the fixing support, and the part for fixing the door lintel inductor is higher than the door lintel, so that the influence on the original height of the elevator door is avoided. Meanwhile, the sensor probe and the elevator door have a certain inclination angle, so that the human body is ensured to be in the sensing range of the sensor when the human body is outside the elevator door. Stainless steel is preferred to the fixed bolster, and ageing-resistant, intensity is high. The fixing bracket made of PVC material can also be selected.

As shown in fig. 3-4, the double-inductor additional type automatic elevator disinfection device adopts an additional elevator power supply 220V alternating current power supply to supply power to an ultraviolet lamp, converts the power into 12V direct current power through a switching power supply to a door head inductor and a top inductor, and provides 3.3V voltage for a controller through a voltage stabilizing circuit. When the sensor senses that a human body passes through, the dry node in the sensor, namely the normally open contact, is closed, the circuit is switched on, the high-low level signal is transmitted to the controller through the 12V solid-state relay, and the ultraviolet lamp is in a closed state at the moment. When two inductors can not sense the human body, the ultraviolet lamp is controlled to be started through outputting 3.3V voltage and passing through the 5V solid-state relay. The system state includes three cases: when one of the door head sensor or the top sensor senses a human body, the sensor sends a signal to the controller, the controller identifies the signal and sends a signal to the ultraviolet lamp, and the ultraviolet lamp is immediately closed; and secondly, when the door head sensor and the top sensor do not sense a human body, the sensors send signals to the controller, the controller identifies the signals and sends signals to the ultraviolet lamp, and the ultraviolet lamp is turned on. And thirdly, emergency occurs. When the elevator has a fault or the inductor has a fault, field personnel immediately press an emergency button to cut off the ultraviolet lamp circuit; when the elevator is overloaded, the fuse is disconnected to protect personnel.

s2: when the human body is not sensed to lintel inductor and top inductor, the inductor signals to the controller, discerns the signal by the controller, to ultraviolet lamp signaling, ultraviolet lamp opens, opens the disinfection, when two inductors all can't detect the human body, begins disinfection work, when predetermineeing time t1, ultraviolet lamp closes, when predetermineeing time t2 again, ultraviolet lamp opens, from this circulation reciprocal.
