When the photoelectric sensor 330 senses the presence of an object, it will prevent the door from closing.

Based on the disinfection bin automatic door provided by the technical scheme, the invention provides a disinfection bin automatic door control method, which comprises the following steps:

s1, detecting whether a person is ready to enter the disinfection bin or not by the first camera and the second camera in real time, and if the person is ready to enter the disinfection bin, entering S2;

s2, controlling the air curtain machine to work to form an air curtain at the bin gate;

s3, opening a bin door;

s4, detecting whether the personnel enter the warehouse or not, if so, carrying out S5, if not, closing a warehouse door after waiting time T1, closing an air curtain machine, and returning to S1;

s5, closing the bin door, then closing the air curtain machine, and finally disinfecting the personnel entering the bin;

and S6, after the disinfection is finished, controlling the air curtain machine to be opened to form an air curtain at the bin door, then opening the bin door, and after the detection personnel leave the disinfection bin, controlling the bin door to be closed to close the air curtain machine.

The waiting time T1 in the control method refers to the upper limit of the time for waiting for personnel to enter the disinfection cabin after the cabin door is opened, and the specific set value of T1 can be adaptively adjusted according to actual conditions.

In the method, the position information of the detected personnel can be determined by utilizing the rotating angles of the first camera and the second camera and the position coordinates of the first camera and the second camera, so that whether the personnel are ready to enter the disinfection cabin is judged. To illustrate the principle more clearly, as shown in fig. 7, in a semicircular area a with the door as the center, in order to determine whether a person is ready to enter the predetermined area of the disinfection chamber, the first camera and the second camera are respectively arranged at two ends of the bottom edge of the semicircular area a. Angle m represents the angle between the first camera facing direction and the bottom edge of the semi-circular area a and angle n represents the angle between the second camera facing direction and the bottom edge of the semi-circular area a, such that the sum of angle m and angle n is less than ninety degrees, indicating that the person has entered the predetermined area a, the door may be opened, and the sum of angle m and angle n is greater than ninety degrees, indicating that the person has not entered the predetermined area a, without opening the door. It should be noted here that the first camera, the second camera and the detected person form a triangle for three vertices, and the angles m and n are internal angles of the triangle.

The method for detecting whether a person is ready to enter the disinfection bin by the first camera and the second camera comprises the following steps:

s11, detecting whether a person enters a visible range in real time by the first camera, and if the person exists in the visible range, entering S2;

s12, rotating the first camera to enable the lens to face the detected person, and rotating the second camera to face the person;

s13, feeding back the rotation angle information of the first camera and the second camera to an image processor;

s14, judging whether the first camera, the detected person and the second camera are collinear, if so, entering S15, and if not, entering S16;

s15, driving the first camera to slide on the sliding rail for a certain distance by the cylinder, and repeating S12;

s16, calculating the position of the detected person according to the position of the first camera and the rotation angles of the first camera and the second camera;

and S17, judging whether the detected personnel enters the preset area, if the personnel enters the preset area, entering S2, and if the detected personnel does not enter the preset area, repeatedly entering S11.

The predetermined area is an area in front of the door of the disinfection cabin, and when a user enters the area, the air curtain machine and the cabin door can be opened to allow the user to enter the disinfection cabin.

The method for enabling the first camera to face the detected person specifically comprises the following steps:

s121, judging whether the detected person is in the center of the visible range, if the person is in the center of the visible range, entering S13, and if the person is not in the center of the visible range, entering S122;

s122, the first camera rotates to the side where the detected person is located by a preset angle a;

and S123, re-entering S121.

The smaller the set angle of the rotation angle a is, the higher the detection accuracy is, but correspondingly, the longer the detection time is required, and in practical application, the adaptive adjustment is required according to the actual installation environment.

On the basis of the control method, the method for detecting whether the person enters the disinfection cabin in the step S4 specifically comprises the following steps:

s41, detecting whether the person steps on the bearing plate or not in real time through the piezoelectric sensor, if yes, entering S42, and if no person is detected to step on the bearing plate after the waiting time T1, entering S43;

s42, after the piezoelectric sensor detects that the personnel leaves the bearing plate, the operation enters S5;

and S43, closing the air curtain after the bin door is controlled to be closed, and entering S1 again.

In order to avoid the people being pinched by the door, the method for closing the door in step S5 specifically includes the following steps:

s51, detecting whether an object blocks at the bin gate in real time by the photoelectric sensor, if so, entering S52, and if not, entering S53;

s52, after the delay time T2, the process re-enters S1;

and S53, controlling the hydraulic motor to work, and further driving the hydraulic cylinder to work, so as to close the bin gate.

The delay time T2 of the control method is the time interval between the next detection by the photoelectric sensor after the photoelectric sensor detects that an object blocks the door and is closed.

When a user needs to disinfect by using the ozone disinfection cabin, the user moves to the disinfection cabin, the first camera 320 and the second camera 340 are both over against the user, the position coordinates of the user are determined through information fed back by the first camera 320 and the second camera 340, and after the user enters a preset area, signals are fed back to the controller 310. The controller 310 controls the air curtain machine 200 to work to form an air curtain at the door to prevent the toxic substances in the disinfection chamber from leaking, and then controls the hydraulic assembly 100 to work to drive the door panel 120 to slide on the guide rail 110 to open the door. After the personnel enter the disinfection cabin, the hydraulic assembly 100 is controlled to work to close the cabin door, then the air curtain machine 200 is controlled to close, and finally the disinfection cabin can disinfect the personnel entering the cabin. After the personnel finish disinfecting, controller 310 controls air curtain machine 200 to work, then opens the door, and after the personnel left the disinfection storehouse, closes air curtain machine 200 after closing the door again. The automatic door of the disinfection cabin provided by the invention can accurately capture the position information of a user, so as to accurately control the opening and closing of the cabin door, thereby avoiding frequent mistaken opening of the cabin door, further avoiding the leakage of a disinfection medium caused by mistaken opening of the cabin door, and reducing the waste of resources. The above-described embodiments of the present invention should not be construed as limiting the scope of the present invention. Any other corresponding changes and modifications made according to the technical idea of the present invention should be included in the protection scope of the claims of the present invention.
