Description

Method for temporarily transforming elevator in public place during epidemic prevention and control period

Technical Field

The invention relates to the technical field of temporary reconstruction of elevators during epidemic prevention and control, in particular to a method for temporarily reconstructing an elevator system in public places such as hospital buildings and the like during epidemic prevention and control.

Background

Hospitals as public places are main places for isolated treatment of confirmed cases during epidemic prevention and control of novel coronavirus, and are also main places for epidemic prevention and control due to relatively large people stream density and population density; since land cost is high and hospitals are usually located in urban central areas, hospital buildings are usually high-rise buildings that must be equipped with multiple elevators.

At present, physical keys, including an up key, a down key and a floor number key, are generally arranged in elevators in public places such as hospital buildings for controlling the operation of the elevators, for example, the technical scheme disclosed in patent document with publication number CN 110857202A. As the main transmission path of the novel coronavirus is respiratory droplet transmission and contact transmission, the elevator three-dimensional space area with small space, tightness and large people flow needs to be disinfected regularly, particularly the disinfection at the position of a key and the disinfection of air in a car, but the currently commonly adopted disinfectant usually has pungent smell and certain corrosivity and cannot be disinfected regularly.

In order to solve the above technical problems, a virtual key pad is generally projected and imaged based on the existing projection technology to reduce infection caused by touch, for example, the technical proposal of projecting virtual key pads disclosed in patent documents with patent numbers CN102701033A, CN204675569U, CN108483154A, etc., but during epidemic prevention of viruses such as new coronavirus which are transmitted through respiratory droplets and contact, the elevator with such a structure still has the following problems and is not favorable for epidemic prevention and control: (1) the virtual keys projected on the side wall of the elevator car or the control panel outside the elevator still need to be touched by hands, and the number of projection devices is increased along with the increase of the number of floors, so that the cost is increased a lot, and the existing elevator system is difficult to improve by using the projection technology to achieve the purpose of epidemic prevention; (2) if no additional trigger control is added, a virtual key always in a projection state needs a lot of energy consumption; (3) the disinfection liquid still needs to be disinfected regularly; (4) the number of people in the car is difficult to regulate and control, people mainly rely on the people to feel, and the effect is difficult to see, and the lift-cabin door is opened and shut, not only people do not get into the elevator because inside personnel are more, and can lead to the pause up-and-down of elevator and be unfavorable for the improvement of carrying efficiency.

91 and 92 may be restored by removing the plates of the outer control panel 12 and the inner control panel 11, inserting the cables through the gaps, or drilling threading holes in the panels, and blocking the cables by means of adhesion or welding after the period of epidemic prevention and control. The pedal calling landing button device 13 is directly arranged on the ground without being fixed; the virtual key projection device 14 may be fixed to the support plate 150 by a fastening member such as a bolt, and the ultraviolet generating device 17 may be fixedly connected by a bolt, a wire, or the like after the ceiling of the car is removed, and the cable 94 for supplying power to the ultraviolet generating device 17 may be connected through the ceiling. The structure of the bearing plate 15 can be arranged according to the existing bearing device.

A software upgrading step S3, wherein the control program in the control system 10 is upgraded so as to control the finger-pressed call key on the outer control panel to be lighted up or extinguished when the pedal call key is triggered by pedal in the running process of the elevator 1; when the detection data of the pressure sensor indicates that a person newly enters the car 2, the virtual key projection device 14 is started to project at least a virtual pedal layer number key on the imaging panel 93; when the virtual pedal layer number key is triggered in a shielding manner, the finger-pressing layer number key 110 on the inner control panel 11 can be controlled to be lighted up or extinguished in an indicating manner; 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; when the detection data of the pressure sensor represents that the number of people in the car 2 exceeds the preset number of people, people entering the car to open the door is suspended; the foot key and the finger key can control the traction system at the same priority level.

Wherein, the 'pedal key and the finger key can control the traction system at the same priority level' is configured: when calling, a passenger can call by triggering one of the pedal up call button 32 and the pedal down call button 31, or by triggering one of the finger down button 121 and the finger up call button 122, and the triggering modes of the two buttons have the same priority level, so that the calling can be selected in the same priority level; (2) when the floor is selected, a passenger can select the floor by triggering one of the eight virtual pedal floor buttons, or can select the floor by triggering one of the eight finger-pressing floor buttons, and the triggering modes of the two buttons have the same priority level and can select the floor with the same priority level; therefore, when the temporarily-improved external pedal call key device 13 and the virtual key projection device 14 have problems, the entity keys on the control panel can be selected for triggering control, and the use safety can be ensured.

"when the pedal call key is triggered by the pedal, the finger on the outer control panel is controlled to press the call key to indicate the lighting or the extinguishing" is configured to "when the passenger can call by triggering the pedal up call key 32, the finger presses the down key 121 to correspondingly light up; when a passenger can call by triggering the pedal down call button 31, the finger-pressing up button 120 is correspondingly lightened, and the corresponding finger-pressing button is extinguished as the same as the operation rule of the existing elevator, for example, after the elevator is turned on and off; when the virtual pedal floor number key is triggered in a shielding manner, the finger-pressing floor number key 110 on the control inner panel 11 is controlled to be lighted or extinguished in an indication manner, and the control inner panel is correspondingly configured to control that "when a passenger triggers one of the eight virtual pedal floor number keys to select a floor, the corresponding numerical value of the eight finger-pressing floor number keys is lighted, and the button is extinguished as the same as the operation rule of the existing elevator, for example, when the elevator door is opened and the corresponding floor number is reached; "; therefore, in the using process, the on-off of the entity keys arranged on the control panel can be utilized to represent the selection result of the elevator to passengers, namely, the existing elevator components can be fully utilized to save the cost, and the using habit of the passengers does not need to be changed greatly.

"the virtual key projection device 14 is turned on to project at least a virtual number of steps key on the imaging panel 93 when the detection data of the pressure sensor indicates that a person newly enters the car 2" is configured:

(1) in consideration of the epidemic situation prevention and control period, compared with ordinary times, the number of people can be reduced and can be regularly arranged and separated by a certain distance, so that the people cannot be crowded too much, the bearing capacity on the bearing plate can be judged to be increased or reduced every time, the increase or reduction amount is not less than a preset value, for example, the weight of a human body capable of walking independently is not larger than the preset value, and a child holding the adult is not considered, so that the weight of the human body on the preset value can be increased or reduced every time, the new people entering or going out is represented, and the number of people in the lift car can be counted by means of the weight and the increase and decrease times.

(2) If the weight on the bearing plate is smaller than a preset value, for example, less than 5 kilograms, the elevator can judge that no person is in the car, and because the elevator is usually installed in public places such as hospital buildings, few things can fall into the elevator, so that whether people are in the elevator can be judged better. 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; "is 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 presses a calling elevator key or a pedal calling elevator key to be 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 ultraviolet lamp tubes with different sizes. And for the elevator going from other floors to the floor where the elevator is called by people currently or at the current floor, if the ultraviolet disinfection is not completed, the elevator door cannot be opened. In addition, for the setting of the fourth preset time length, the setting can be shorter when the number of people is more in the daytime and the like, and the setting can be longer at night so as to meet the actual requirement.

(2) When the number of the cars in the leisure ultraviolet disinfection state reaches more than two, if a calling key is triggered, and no car goes up and down to the corresponding floor and can be subjected to ultraviolet disinfection for the fourth preset time before the elevator door of the floor is opened, the car which goes up and down to the corresponding floor and has the longest ultraviolet disinfection time before the elevator door of the floor is opened is controlled to go up and down in response to the triggering of the calling. In the rule, the elevator is disinfected by fully utilizing the up-down time of the elevator, namely the longest one of the time from up-down to the current calling floor number plus the ultraviolet disinfection is controlled to respond to the calling request, so that the problem that passengers think the elevator has a problem 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 the disinfection is completed and the call is nearest, the control is closest to respond to the call request.

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 consciously 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, and 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 detected number of times of continuous pedal triggering is more than N and the time length of two adjacent pedal triggering is less than a fifth preset time length, 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 operation efficiency of the elevator caused by unreal multiple foot-operated triggering of people is avoided.

(2) When the detection data of the pressure sensor indicates that the newly-entered elevator personnel at the current floor number is one person, the virtual key projection device closes the projection imaging of the virtual pedal key after starting for a first preset time period or after being triggered by the pedal for a second preset time period, wherein the second preset time period is less than the first preset time period. 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 number of newly-entered elevator people at the current floor 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 layer number of 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.
