(1) During considering epidemic prevention and control, at ordinary times, the number of people can reduce and all can be regular lining up and be separated by a certain distance, thereby can not crowd excessively, thereby can judge that the bearing capacity on the bearing plate increases or reduces at every turn, and this increase amount or reduction amount is not few default, for example the human weight that can independently walk is usually not greater than the default, and do not consider the child of embracing at the adult, thereby can think increase at every turn or reduce the volume above the predetermined value, the sign has people to enter newly or go out, thereby can utilize weight and increase and decrease number of times and statistics people's quantity in the car.

(2) If the weight on the bearing plate is smaller than a preset value, for example, below 5 kilograms, it can be judged that no person exists in the lift car, and because the lift is usually installed in public places such as hospital buildings, few things can fall into the lift car, so that whether a person exists in the lift car can be better judged. In addition, in the running process, if the weight smaller than the preset threshold value is monitored in the car, an instruction can be sent to the monitoring platform to request the monitoring platform to judge whether people exist in the car through the camera, and if the weight is not monitored, operations such as disinfection can be performed.

(3) Therefore, when a person enters the novel device, the virtual pedal layer number keys are projected for a novel person to select.

"when the detection data of the pressure sensor represents that no person exists in the car 2, the ultraviolet generating device 17 is controlled to carry out ultraviolet disinfection on the car 2; "configured to: "according to the above algorithm of people counting, when the load bearing amount on the bearing plate is less than a preset threshold value, for example, 5 kg, it is judged that the bearing plate is not occupied, so that the ultraviolet disinfection can be performed. ", and can be controlled according to the following rules during the operation process:

(1) In the ultraviolet disinfection process, if a finger is used for pressing a calling elevator key or a pedal calling elevator key is triggered and the ultraviolet disinfection duration is less than a fourth preset time, ultraviolet disinfection is performed for at least the fourth preset time before the elevator door of the floor is opened when the elevator car 2 moves up and down to the corresponding floor, so that the ultraviolet disinfection time is not less than the fourth preset time, the fourth preset time is set according to experimental data, and field setting is performed according to the number of the elevator cars and the number of ultraviolet lamp tubes with different sizes. And if the elevator moves from other floors to the floor where the elevator is called currently or is at the current floor, the elevator door cannot be opened if ultraviolet disinfection is not completed. In addition, for the setting of the fourth predetermined time period, the setting may be shorter when the number of people is large in the daytime and the like, and longer in the evening, so as to meet the actual demand.

(2) When the number of the cars in the leisure ultraviolet disinfection state reaches more than two, if a calling elevator key is triggered, and no car goes up and down to the corresponding floor and can be subjected to ultraviolet disinfection until the fourth preset time before the elevator door on the floor is opened, the car which is the longest in ultraviolet disinfection time before the elevator door on the floor is opened and responds to the triggering of the calling elevator to go up and down is controlled to go up and down to the corresponding floor. In the rule, the up-down time of the elevator is fully utilized for disinfection, namely the longest time from the up-down time to the current calling floor number plus the ultraviolet disinfection is controlled to respond to the calling request, so that the problem of the elevator, which is considered by passengers, is reduced; in addition, if the current calling floor has a car but the disinfection time is not the longest, the elevator can be controlled to go up and down to other floors, so that the passengers can not mistakenly recognize that the elevator is abnormal.

(3) When the number of the cars in the leisure ultraviolet disinfection state reaches more than two, if a call key is triggered and at least one car moves up and down to a corresponding floor and can perform ultraviolet disinfection to a fourth preset time before the elevator door of the floor is opened, the car which has the shortest time to move to the floor in the cars with the fourth preset time in disinfection is controlled to move up and down in response to the triggering of the call. Namely, in the rule, if ultraviolet disinfection is finished and the running time exceeds the time which is closer to the current calling floor and the disinfection time is close, the control is carried out to control the up-down going without disinfection and closer; if there is a disinfecting and closest one, the control responds the call request closest.

When the detection data of the pressure sensor represents that the number of people in the car 2 exceeds the preset number of people, the person entering type door opening is suspended; the rule is particularly suitable for the epidemic situation prevention and control period, people can voluntarily reduce the number of people entering the elevator, otherwise, the elevator is stopped and started all the time, but outside people do not necessarily enter the elevator, so that the problem of low elevator operation efficiency is caused.

In addition, the control program can be upgraded to achieve the following functions, so that epidemic prevention and control can be better performed:

(1) When the data detected by the pressure sensor indicates that the current floor number of newly-entered elevator personnel is N people, N is more than or equal to 2, if the frequency of continuous pedal triggering is detected to be more than N and the duration of two adjacent pedal triggering times is less than a fifth preset duration, the loudspeaker installed in the elevator car 2 is controlled to be started to prompt the user to pedal again to trigger and select the target floor, and the current continuous pedal triggering selection is eliminated. The fifth preset time is set according to the actual situation on site, so that the low running efficiency of the elevator caused by unreal multiple pedal triggering of people is avoided.

(2) When the detection data of the pressure sensor represents that the current floor number newly-entered elevator is one person, the virtual key projection device closes the projection imaging of the virtual pedal key after starting the first preset time length or after being triggered by the pedal for the second preset time length, and the second preset time length is smaller than the first preset time length. The first preset time length and the second preset time length are set according to the actual situation or the experience statistical structure on site, so that the energy consumption generated by projection can be reduced, and the interference to passengers can be reduced.

(3) When the detection data of the long-pressure safety steam indicates that the current floor number of newly-entered elevator personnel is N people, N is more than or equal to 2, and the virtual key projection device closes the projection imaging of the virtual pedal key after being started for a third preset time or after being triggered by the pedal for N times for a second preset time; the third predetermined time length is greater than the first predetermined time length and less than N times the first predetermined time length. The projection time is effectively prolonged according to the number of people, and the energy consumption is reduced while the power consumption is reduced.

In addition, the control system 10 may be provided with a communication unit for communication connection with the monitoring platform, which may be a wired communication unit or a wireless communication unit; therefore, when the number of the newly entered people is selected to be selected by triggering and selecting through pressing the key by fingers twice continuously, the maintenance notification information is sent to the monitoring platform through the communication unit. Thereby monitoring the working state of the non-finger-pressed key.

In the use process, because each part can be dismantled, can dismantle during non-epidemic situation prevention and control to can make full use of people's the not public mind and carry out better arranging during epidemic situation prevention and control.
