Description

Technical Field

[0001] The present application relates to the technical field of path planning, and in particular to a disinfection and purification method and system based on path planning. Background Art

[0002] With the prevalence of respiratory infectious diseases in recent years, medical air purifiers have received more and more attention from the society. Medical air purifiers refer to medical epidemic prevention-grade air purifiers that can be used in medical systems. Medical air purifiers use air filtration systems to continuously purify the gas in the external space through the air inlet, filter screen and air purification filter, and then put it back into the air to achieve the effect of keeping the air in the space clean.

[0003] In traditional technology, medical air purifiers are generally fixed, but whether it is a wall-mounted medical air purifier or a cabinet-type medical air purifier, it can only disinfect and purify the air within a fixed range, but cannot fully purify the entire range. In order to solve this problem, people have vigorously developed mobile air purifiers. For example, Chinese patent CN110227303A discloses an air purifier, which includes: a guide rail part, which is used to be set on the wall of the room; a purifier body, and the purifier body is movably set on the guide rail part. In addition, Chinese patent CN104764106A discloses a purification method for an air purification device, which determines the target purification area according to the air quality of each area and controls the motion unit to drive the air purification device into the target purification area, so that the air purification device can be easily moved to different areas of the room for purification.

[0004] However, existing mobile air purifiers lack specificity in complex environments such as hospitals. Some people in the hospital suffer from respiratory infectious diseases, while others suffer from other diseases. If they are not differentiated and directly purified, the places where people with respiratory infectious diseases pass by may not be disinfected and purified in time, posing a certain risk of infection.

DETAILED DESCRIPTION

[0048] The present solution is described below in conjunction with the accompanying drawings and specific implementation methods.

[0049] Figure 1 A schematic diagram of a disinfection and purification method based on path planning provided in an embodiment of the present application, see Figure 1 The disinfection and purification method based on path planning in this embodiment includes:

[0050] S101, determining a first position and a second position of a user corresponding to adjacent information collection in a hospital.

[0051] When a user enters a hospital for medical treatment, the department where the user is treated will collect the user's characteristic information through a face collection device and a medical information collection device. The characteristic information includes: face information and medical information. After the user has finished the medical treatment at the department where the user is treated, he or she may undergo a secondary examination, pay fees, or get medicine, etc. At this time, the user's medical information will be collected again, and the first collection point and the second collection point for collecting the user's adjacent information will be determined based on the medical information. The positions corresponding to the first collection point and the second collection point are used as the first position and the second position.

[0052] When the user visits the treatment department, the user information will be collected by the collection equipment in the department. After the treatment, the user will go to the payment window to pay according to the doctor's treatment instructions. When the user arrives at the payment window to pay, the information collection equipment at the payment window will collect the user information again. At this time, the two information collections of the user information between the treatment department and the payment window are the adjacent information collections of the user. Therefore, the treatment department and the payment window are respectively used as the first position and the second position in this embodiment. If the user goes to the laboratory for blood test after completing the payment, the payment window will be dynamically updated to the first position of the new path, and the blood drawing window position where the user arrives at the laboratory will be used as the second position. Correspondingly, if the user has to go to different departments of the hospital for examination, there will be information collection equipment to collect user information. According to the different paths, the second position determined later will dynamically become the first position of the new path. S102, determine the disinfection and purification path of the medical mobile air purifier according to the first position and the second position.

[0053] There are multiple paths that users can choose from to reach the second location from the first location, and each path passes through different locations. Based on this, first obtain the hospital floor plan, and then obtain all the third locations that the user may pass through from the first location to the second location based on the hospital floor plan. The third locations include multiple locations, such as corridors, aisles, elevator entrances, etc., and determine the location of the location in the hospital floor plan. Then, all the paths between the first location and the second location are generated based on the third locations as the disinfection and purification paths.

[0054] Since there are multiple possible paths for the user to reach the second location from the first location, and too many paths will occupy too many medical mobile air purifiers, and there is generally only one path for the user to reach the second location from the first location, for this reason, in this embodiment, the camera in the hospital is utilized, and the camera is used to identify the user to determine the place the user has passed, thereby reducing the length of the disinfection and purification path.

[0055] Specifically, a camera distribution plan of the hospital is obtained, and the cameras in the hospital perform facial feature recognition on people in the shooting area based on the facial information. If the camera recognizes the user, the position of the camera is determined according to the camera distribution plan, and then the position of its shooting area in the hospital floor plan is determined according to the position of the camera. The position of the user in the hospital floor plan is determined through image feature recognition, and the position of the user in the shooting area of ​​the camera is used as path node information.

[0056] In this embodiment, in order to more accurately determine the user's position, a rectangular anchor frame is set in the shooting area of ​​the camera. Figure 2 When the user is identified, the user is locked using an anchor frame, and the center point of the anchor frame is determined as the path node information.

[0057] Since the camera's shooting range is an area, if only one position is used as the path node information, errors are inevitable. Figure 3 A plurality of anchor frames 2 are arranged in the shooting area 1 of the camera, and only one anchor frame 2 locks the user 3 at the same time.

[0058] Specifically, the interval time window for the anchor frame to lock the user is determined, and the interval time window can be flexibly set according to the size of the camera shooting area 1. In this embodiment, the shooting length of the indoor camera is 25 meters, and the walking speed of ordinary people is about 1 meter per second, so it can be determined that the time for ordinary people to pass through the shooting area 1 of the camera is 25 seconds. In this embodiment, at least 3 path node information is obtained in the shooting area 1 of the camera, so the interval time window is set to 10s. Considering that the elderly or special groups have a slower walking speed, which leads to a longer passage time, in order to avoid that the 3 anchor frames 2 do not meet the anchoring requirements, 6 anchor frames 2 are set in this embodiment. When the user 3 appears in the shooting area 1 of the camera at the first moment, the first anchor frame 4 is controlled to lock the user 3, and the first anchor frame 4 is any anchor frame 2. After that, different anchor frames 2 are used to lock the user 3 at the interval time window as a unit time interval until the user 3 walks out of the shooting area 1 of the camera. In this way, multiple path node information is obtained, and then the position of each path node information in the hospital floor plan is determined through image feature recognition, and then the path nodes at the first position, the second position and the two positions are connected in sequence to generate a disinfection and purification path connecting the first position and the second position. In this embodiment, a straight line connection is used for connection. Since the medical mobile air purifier can achieve regional purification, the use of a straight line to connect the path nodes will not affect its disinfection and purification effect.

[0059] Since the camera's shooting area is a range, it is impossible to include all disinfection and purification paths. If there is a monitoring blind spot between adjacent cameras, all fourth positions that users may pass through between the two camera shooting areas are determined. The fourth positions include multiple ones, and the supplementary path information between the two camera shooting areas is generated through the fourth positions. Specifically, the positions of the two cameras are determined according to the camera distribution plan, and then the positions of their shooting areas in the hospital floor plan are determined according to the positions of the two cameras. If there is a monitoring blind spot between the two cameras, the position of the location in the blind spot in the hospital floor plan is determined, and the location in the blind spot is the fourth position. The supplementary path information is generated according to the position of the location in the blind spot in the hospital floor plan.

[0060] In this embodiment, it is taken into account that the hospital is a multi-story building, and each medical mobile air purifier only works on a single floor. If the disinfection and purification path contains a fifth position that the medical mobile air purifier cannot pass through, such as stairs, elevators or other inaccessible places, the position of the location in the hospital floor plan is determined, and after the medical mobile air purifier reaches the fifth position, the information of the fifth position is uploaded to the system, and the fifth position is deleted from the disinfection and purification path. If there is still an area that needs to be disinfected and purified after deleting the fifth position, the remaining path is disinfected and purified according to the hospital floor plan, and the staff performs manual disinfection and purification according to the fifth position.

[0061] S103, disinfecting and purifying the area corresponding to the disinfection and purification path according to the disinfection and purification path.

[0062] See also Figure 4 In this embodiment, the first path length threshold is 1000 meters. The trajectory of the disinfection and purification path on the hospital floor plan is determined, and then the length of the disinfection and purification path is obtained. If the length of the disinfection and purification path is greater than the set first path length threshold, the first medical mobile air purifier 8 sends a broadcast signal 9 when performing disinfection and purification along the disinfection and purification path. The broadcast signal 9 contains information about the disinfection and purification path.

[0063] The middle path node 7 of the disinfection and purification path is determined according to the trajectory of the disinfection and purification path on the hospital floor plan and the length of the disinfection and purification path. Then, the second medical mobile air purifier 10 closest to the middle path node 7 of the disinfection and purification path is determined from the idle medical mobile air purifiers that have received the broadcast signal 9. The second medical mobile air purifier 10 goes to the middle path node 7. After the second medical mobile air purifier 10 reaches the middle path node 7, it disinfects and purifies according to the remaining disinfection and purification path from the middle path node 7 to the second position 6. After the first medical mobile air purifier 8 disinfects and purifies to the middle path node 7, it ends the disinfection and purification and enters the idle state.

[0064] Through the above method, an overly long disinfection and purification path is split into two sections. The path from the first position 5 to the middle path node 7 is disinfected and purified by the first medical mobile air purifier 8, and the path from the middle path node 7 to the second position 6 is disinfected and purified by the second medical mobile air purifier 10, which greatly shortens the disinfection and purification time.

[0065] Corresponding to the disinfection and purification method based on path planning provided in the above embodiment, the present application also provides an embodiment of a disinfection and purification system based on path planning.

[0066] See also Figure 5 The disinfection and purification system 20 based on path planning in the embodiment of the present application includes:
