Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be noted that the following examples are only illustrative of the present invention, and do not limit the scope of the present invention. Similarly, the following examples are only some but not all examples of the present invention, and all other examples obtained by those skilled in the art without any inventive work are within the scope of the present invention.

The automatic elevator disinfection method comprises the following steps:

1) whether passengers exist in the elevator is detected through an infrared detector.

2) Camera modules are arranged at the preset distance from each floor to the elevator path and at the waiting area of each floor of the elevator for obtaining images at corresponding positions; the preset distance is determined according to the preset spraying disinfection time, the preset spraying disinfection time in the scheme is 10-15s, and the preset distance is 20-30m according to the walking speed of a normal person about 2 m/s.

4) when the figure image is detected in the image at the elevator waiting area, judging whether the time required by the elevator to move to the floor is more than the preset time for spraying disinfection, if so, spraying disinfection is carried out; if not, the spraying sterilization is not carried out; wherein the time required for the elevator to move to the floor can be calculated according to the normal lifting speed of the elevator and the height distance of the floor.

5) Under the condition that no person is carried in the elevator, when a person image is detected in an image at a preset distance of an elevator path and no person image is detected in an image at an elevator waiting area, judging whether the sum of the time T for the person to travel from the preset distance of the elevator path to the elevator waiting area and the time T for the elevator to move to the floor is greater than the preset spraying disinfection time or not, if so, spraying disinfection is carried out; if not, the spraying sterilization is not carried out; wherein, the time for judging the person to travel from the preset distance of the elevator path to the elevator waiting area is determined according to the length of the preset distance in 2), and if the preset distance is 20m and the walking speed of the normal person is 2m/s, the time T is set to 10 s; and calculating the time T required by the elevator to move to the floor according to the normal lifting speed v of the elevator and the floor height distance h, namely, T is h/v, and then comparing the T + T with the preset spraying disinfection time.

The elevator is disinfected according to a preset interval disinfection time period, namely, the elevator is judged whether to have idle time to disinfect the elevator by adopting the method every preset time, and the interval time period is usually set to be 50-60 min.

When the elevator door receives an opening instruction in the process of spraying and disinfecting, the spraying and disinfecting equipment stops working; under the condition of avoiding misjudgment and the like, the spraying and disinfecting equipment is still spraying and disinfecting when passengers enter the elevator. As a further improvement, when the elevator door receives an opening instruction in the process of spraying and sterilizing, the spraying and sterilizing equipment is opened after emergency reverse exhaust for a preset time; the preset time is about 1-1.2 times of the current spraying time so as to avoid the stimulation of the respiratory tract of a user caused by heavy smell of the disinfectant.

Further, if the elevator is not disinfected within the preset interval disinfection time period, when no passenger is detected in the elevator, the elevator stops responding to the uplink and downlink call button requests, and stops for the preset disinfection time to spray and disinfect the interior of the elevator; when the preset interval disinfection time period is exceeded and no person is carried by the elevator, the operation of the disinfection equipment is automatically stopped to spray disinfection setting time to the interior of the elevator, and the time is changed to 10-15s in the scheme.

Further, if the plurality of elevators are not disinfected within the preset interval disinfection time period, the elevators are sequentially stayed for the preset disinfection time to spray and disinfect the interiors of the elevators according to the sequence of the times when passengers are not detected in the elevators; that is, when a plurality of elevators are not disinfected in the preset interval disinfection time, each elevator is stopped one by one for disinfection, and when one elevator is disinfected, other elevators can normally work to avoid influencing the normal use of the elevator.
