Description

Technical Field

[0001] This invention relates to the field of disinfection technology, and in particular to an intelligent disinfection system and method. Background Technology

[0002] Currently, many crowded public places require regular disinfection, especially high-risk places such as hospitals where pathogens exist. Precise and comprehensive disinfection is essential; inadequate disinfection can lead to serious infectious disease outbreaks. Existing indoor disinfection methods mostly rely on manual inspections. However, manual inspections have drawbacks: small inspection areas, long time commitments, and large workloads. For large disinfection areas, a significant amount of manpower is required. Therefore, the use of disinfection robots has emerged as a solution.

[0003] For example, invention patent CN114668880A discloses a disinfection and epidemic prevention intelligent inspection robot, including a vehicle body and four wheels installed on both sides of the vehicle body. The four wheels are driven by four drive motors installed inside the vehicle body, and the four drive motors are powered by a battery installed inside the vehicle body. The vehicle body is equipped with an outdoor disinfection mechanism and an indoor disinfection mechanism. An intelligent detection mechanism is installed on the top of the vehicle body. The outdoor disinfection mechanism includes a first disinfection box installed inside the vehicle body. The top of the first disinfection box is equipped with a first sealing cover. A quick connector is installed on the front surface of the first disinfection box.

[0004] The invention patent with publication number CN111617276A discloses an ultraviolet disinfection robot, including a mobile chassis and an ultraviolet light-emitting disinfection device. The ultraviolet light-emitting disinfection device is mounted on the mobile chassis. The mobile chassis is also provided with a protective device for blocking ultraviolet light. In the robot's forward direction, the protective device is located behind the ultraviolet light-emitting disinfection device and is used to block the ultraviolet light emitted by a portion of the ultraviolet light emitted by the ultraviolet light-emitting disinfection device.

[0005] Chinese patent application CN113171472A discloses a disinfection robot. The disinfection robot includes an electronic control unit, a first communication unit, and an image acquisition device. The electronic control unit is configured to: determine whether a living being is an adult in the vicinity of the robot; if so, communicate with the living being's name tag via the first communication unit to obtain the user's identification information; and based on the identification information, determine whether the user has gesture command permissions; if so, use the image acquisition device to acquire the user's gesture image and analyze it to derive the gesture; and execute the operation corresponding to the gesture, wherein the operation includes at least one of stopping, turning left, turning right, backing up, going upstairs, and going downstairs.

[0006] Existing disinfection robots typically perform disinfection using manually set disinfection paths. However, in actual use, hospitals and other facilities often have areas requiring different disinfection methods. Therefore, a single UV disinfection robot or spray disinfection robot cannot comprehensively disinfect every area. Furthermore, due to limitations in battery power and / or disinfectant storage capacity, each use of UV and / or spray disinfection robots requires pre-setting their movement paths, resulting in low disinfection efficiency.

[0007] To address the shortcomings of existing technologies, this invention provides an intelligent disinfection system and method.

[0008] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this invention, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that the present invention does not possess the features of these prior art. On the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art.

The intelligent disinfection system includes at least: several disinfection robots, an information collection device, and a central server. Preferably, the disinfection robots and the information collection device are connected to the central server via wired or wireless means. The disinfection robots disinfect the disinfection area using a first disinfection method based on sterilizing light and / or a second disinfection method based on disinfectants. The information collection device collects environmental information about the disinfection area and uploads it to the central server. The central server divides the disinfection area into sub-disinfection areas adapted to the first and / or second disinfection methods based on the environmental information. The central server dispatches the disinfection robots to perform disinfection based on the sub-disinfection areas. Preferably, the environmental information includes at least the spatial volume of the disinfection area, the distribution of facilities, and personnel activities.

[0010] Preferably, when disinfecting an area requiring disinfection, the intelligent disinfection system of the present invention divides the disinfection area into sub-disinfection areas suitable for different disinfection methods based on differences in environmental information such as spatial volume, facility distribution, and personnel activities. The intelligent disinfection system then dispatches the disinfection robot according to the divided sub-disinfection areas. Preferably, when a sub-disinfection area changes, the intelligent disinfection system can respond to the change by dispatching the disinfection robot, thereby achieving dynamic control of the disinfection robot.

[0011] Preferably, the intelligent disinfection system collects environmental information of the disinfection area in real time through the information collection device and uploads it to the central server. This allows the central server to set the movement route of the disinfection robot based on the real-time changes of the sub-disinfection area, thereby ensuring the disinfection efficiency of the intelligent disinfection system and avoiding the problem of low disinfection efficiency caused by pre-setting the walking path of the disinfection robot.

[0012] According to a preferred embodiment, the central server generates a disinfection task based on the sub-disinfection area and sends it to the disinfection robot. Preferably, the disinfection task includes at least the location of the disinfection area, the disinfection method, and the movement route of the disinfection robot.

[0013] Preferably, when the disinfection method adapted to the sub-disinfection area changes, the central server can update the disinfection task according to the change of the sub-disinfection area, thereby adjusting the movement route and / or disinfection method of the disinfection robot to ensure the disinfection efficiency of each sub-disinfection area.

[0014] According to a preferred embodiment, the disinfection robot includes at least a processing module, a communication module, and a disinfection module. The processing module is electrically connected to both the communication module and the disinfection module. The processing module establishes a data transmission channel with the central server through the communication module to receive disinfection tasks issued by the central server or upload the status information of the disinfection robot. Preferably, the disinfection module may be an irradiation disinfection device and / or a spray disinfection device mounted on the disinfection robot.

[0016] According to a preferred embodiment, the disinfection robot further includes a movement module electrically connected to the processing module. Preferably, in response to receiving the disinfection task, the processing module controls the movement of the movement module to cause the disinfection robot to move along the movement path in the disinfection task, and the processing module controls the start and stop of the disinfection module to cause the disinfection robot to disinfect the sub-disinfection area.

[0019] Preferably, when dividing the sub-disinfection areas, the central server can divide the first disinfection area suitable for irradiation disinfection and the second disinfection area suitable for atomization disinfection based on the distribution of facilities and personnel activities in the disinfection areas.

[0020] When using atomized disinfection to disinfect areas containing equipment such as CT scanners and MRI machines, the disinfection robot sprays water-based disinfectants, increasing humidity and creating a high-humidity environment. This can cause moisture-absorbing materials in the equipment, such as printed circuit boards and packaged components, to absorb excessive moisture, leading to contamination or short circuits and ultimately damaging the equipment's functionality. Preferably, the central server can divide the disinfection area into sub-disinfection zones based on the presence of working equipment. Preferably, the central server can designate areas containing equipment such as CT scanners and MRI machines as first disinfection zones, disinfecting them through irradiation to prevent equipment failure due to short circuits or other reasons within the first disinfection zone.

[0021] Preferably, the central server can divide the area where people are active into a second disinfection area and disinfect it by means of atomization disinfection, thereby avoiding damage to the human body caused by sterilization light irradiation.

[0022] According to a preferred embodiment, the central server acquires the status information of the disinfection robot and generates the disinfection task based on the status information and the sub-disinfection area. Preferably, the central server can determine the mobile distance of the disinfection robot based on its battery level, or the central server can determine the disinfection space volume of the disinfection robot based on its remaining disinfectant level.

[0023] Preferably, the central server generates the disinfection task based on the status information of the disinfection robot and the sub-disinfection area, so that the central server can set up combined disinfection tasks based on the task execution capabilities of the disinfection robot. That is, when generating the disinfection task, the central server allocates the disinfection areas to be handled by each disinfection robot, thereby reducing the disinfection time.

[0024] According to a preferred embodiment, the information acquisition device includes at least an image acquisition device for acquiring image information of the disinfection area.

[0025] Preferably, the central server can determine the disinfection completion status of the disinfection robot in the sub-disinfection area by the movement trajectory of the disinfection robot in the disinfection area, particularly the movement trajectory of the disinfection robot in the sub-disinfection area. Preferably, the disinfection robot has an effective disinfection range, and the central server can determine the area disinfected by the disinfection robot in the sub-disinfection area based on the effective disinfection range and the movement trajectory of the disinfection robot in the sub-disinfection area. When the disinfected area covers the sub-disinfection area, it can be considered that the disinfection robot has completed the disinfection of the sub-disinfection area.

[0026] According to a preferred embodiment, the disinfection robot includes at least a first disinfection robot that uses a first disinfection method of emitting sterilizing light and a second disinfection robot that uses a second disinfection method of releasing disinfectant.

[0027] Preferably, after dividing the disinfection area into several first disinfection areas suitable for irradiation disinfection and several second disinfection areas suitable for atomization disinfection, the central server can generate a movement map of a first disinfection robot composed of several first disinfection areas and a movement map of a second disinfection robot composed of several second disinfection areas. Preferably, the central server can set the movement routes of each disinfection robot according to the movement maps, thereby using a combination of multiple first disinfection robots and multiple second disinfection robots to perform disinfection tasks, improving disinfection efficiency.

[0043] Preferably, the central server 130 divides the disinfection area into sub-disinfection areas based on environmental information, using either irradiation disinfection or atomization disinfection. The central server 130 then dispatches disinfection robots 110 to perform disinfection based on the sub-disinfection areas.

[0044] Preferably, the central server 130 generates disinfection tasks based on the sub-disinfection areas and sends them to the disinfection robot 110.

Preferably, the central server 130 can set the movement routes of each disinfection robot 110 according to the movement map, thereby using a combination of multiple first disinfection robots and multiple second disinfection robots to perform disinfection tasks, improving disinfection efficiency.

[0050] Preferably, the division of sub-disinfection zones is based on a set of established rules and changes according to the environmental information of the disinfection zone. Preferably, the sub-disinfection zone includes at least a first disinfection zone using irradiation disinfection and a second disinfection zone using atomization disinfection.

[0051] Preferably, when dividing the sub-disinfection areas, the central server 130 can divide the first disinfection area suitable for irradiation disinfection and the second disinfection area suitable for atomization disinfection based on the distribution of facilities and personnel activities in the disinfection areas.

[0052] When using atomized disinfection to disinfect areas containing equipment such as CT scanners and MRI machines, the disinfection robot 110 sprays water-based disinfectant, increasing humidity in the disinfection area and creating a high-humidity environment. This can cause moisture-absorbing materials in the equipment, such as printed circuit boards and packaged components, to absorb excessive moisture, leading to contamination or short circuits and impaired equipment functionality. Preferably, the central server 130 can divide the disinfection area into sub-disinfection areas based on whether working equipment is present. Preferably, the central server 130 can designate areas containing equipment such as CT scanners and MRI machines as first disinfection areas and disinfect them using irradiation disinfection, thereby preventing equipment failure due to short circuits or other reasons in the first disinfection area.

[0053] Preferably, the central server 130 can divide the area where people are active into a second disinfection area and disinfect it by means of atomization disinfection, thereby avoiding the damage to the human body caused by the sterilization light.

[0054] Preferably, the central server 130 can acquire images of the disinfection area through an image acquisition device. Preferably, the central server 130 can divide the disinfection area into sub-disinfection areas based on the images. Preferably, the central server 130 divides the sub-disinfection areas according to the following set of rules: first, the central server 130 determines whether there is equipment such as a CT scanner or MRI scanner in the image; second, the central server 130 determines whether there is human activity in the image. Preferably, the central server 130 can divide the area where there is equipment such as a CT scanner or MRI scanner into a first disinfection area. Preferably, the central server 130 can divide the area where there is no equipment such as a CT scanner or MRI scanner but there is human activity into a second disinfection area. Preferably, for areas where there is neither equipment such as a CT scanner or MRI scanner nor human activity, the central server 130 can divide them into a third disinfection area. Preferably, the third disinfection area can be disinfected by either atomization disinfection or irradiation disinfection. Preferably, the third disinfection area can be an area where there is no human activity and no equipment is placed during disinfection.

[0055] Preferably, after dividing the sub-disinfection areas, the central server 130 can generate disinfection tasks based on the status information of the disinfection robots 110. Preferably, when generating a disinfection task, the central server 130 can determine the power consumption and / or disinfectant dosage of the disinfection robot 110 for disinfecting the space to be disinfected in the sub-disinfection area. Preferably, the central server 130 can also set the movement route of each disinfection robot 110 based on its initial position, power consumption, and / or remaining disinfectant.

[0056] Preferably, the central server 130 may include a processing unit and a storage unit. The storage unit may store the hospital's architectural drawings. The processing unit may mark the location of each sub-disinfection area on the pre-stored architectural drawings, and the processing unit may also determine the movement route of the disinfection robot 110 between each sub-disinfection area based on the architectural drawings, thereby generating a movement map containing the locations of several sub-disinfection areas and the movement routes of the disinfection robot 110 between each sub-disinfection area. When the disinfection area changes, the processing unit of the central server 130 may modify the movement map, thereby realizing online modification of the movement route of the disinfection robot 110, avoiding the problem that the disinfection robot 110 cannot adapt to the dynamic changes in the disinfection environment due to the pre-set walking path.

[0057] Preferably, the central server 130 connects several first disinfection areas to generate a movement map of the first disinfection robot, which includes the locations of the several first disinfection areas and the movement routes of the disinfection robot 110 between the first disinfection areas. The central server 130 connects several second disinfection areas to generate a movement map of the second disinfection robot, which includes the locations of the several second disinfection areas and the movement routes of the disinfection robot 110 between the second disinfection areas.

[0058] Preferably, when setting the movement routes of each disinfection robot 110, the central server 130 can determine the movable distance of each disinfection robot 110 based on its battery level. Preferably, the central server 130 can set the movement routes of each disinfection robot 110 in ascending order of their movable distances. Preferably, when all disinfection robots 110 have the same initial position, the distance between the endpoint of the movement route and the initial position of each disinfection robot 110 increases as the movable distance of the disinfection robot 110 increases.

[0059] Preferably, the third disinfection area can be integrated into the movement map of the first or second disinfection robot according to the principle of using the same disinfection method as its previous sub-disinfection area, thereby reducing the number of times the disinfection robot 110 starts and stops. Preferably, the previous sub-disinfection area of ​​the third disinfection area can be the sub-disinfection area where the disinfection robot 110 was located before entering the third disinfection area.

[0060] Preferably, when an obstacle blocks the sterilization light emitted by the first disinfection robot in the third disinfection area using irradiation disinfection and the first disinfection robot cannot bypass the obstacle, the central server 130 can dispatch a nearby second disinfection robot to perform atomized disinfection on the obstacle area. For example, when disinfecting the interior of an unused nurse station, the first disinfection robot cannot enter the nurse station due to access control, and the sterilization light emitted by the first disinfection robot cannot reach the interior of the nurse station due to the obstruction of the enclosure, thus preventing disinfection of the interior area of ​​the nurse station. In this case, the central server 130 can dispatch a second disinfection robot to spray atomized disinfectant, allowing the disinfectant to diffuse into the interior of the nurse station to complete the disinfection.

[0061] Preferably, the central server 130 can determine the environmental information in the disinfection area and the movement trajectory of the disinfection robot 110 in the disinfection area based on the image information acquired by the image acquisition device.

[0062] Preferably, the central server 130 can check the disinfection completion status of the disinfection robot 110 by tracking its movement trajectory in the disinfection area.

[0063] Preferably, when the disinfection robot 110 is performing disinfection, the central server 130 can check the disinfection completion status of the disinfection robot 110 by judging whether the area formed by the effective disinfection range of the disinfection robot 110 moving along the movement trajectory covers the area to be disinfected.

[0064] Preferably, the disinfection robot 110 has an effective disinfection range. The central server 130 can determine the area disinfected by the disinfection robot 110 in the sub-disinfection area based on the effective disinfection range of the disinfection robot 110 and the movement trajectory of the disinfection robot 110 in the sub-disinfection area. When the disinfected area covers the sub-disinfection area, it can be regarded as the disinfection robot 110 has completed the disinfection of the sub-disinfection area.

[0065] Preferably, when disinfecting an area requiring disinfection, the intelligent disinfection system 100 of the present invention divides the disinfection area into sub-disinfection areas suitable for different disinfection methods based on differences in environmental information such as spatial volume, facility distribution, and personnel activities. The intelligent disinfection system 100 then dispatches disinfection robots 110 according to the divided sub-disinfection areas. Preferably, when a sub-disinfection area changes, the intelligent disinfection system 100 can respond to the change by dispatching disinfection robots 110, thereby achieving dynamic control of the disinfection robots 110.

[0066] Preferably, the intelligent disinfection system 100 collects environmental information of the disinfection area in real time through the information collection device 120 and uploads it to the central server 130, so that the central server 130 can set the movement route of the disinfection robot 110 based on the real-time changes of the sub-disinfection area, so as to ensure the disinfection efficiency of the intelligent disinfection system 100 and avoid the problem of low disinfection efficiency caused by the pre-setting of the walking path of the disinfection robot 110.

[0067] Preferably, when the disinfection method adapted to a sub-disinfection area changes, the central server 130 can update the disinfection task according to the change of the sub-disinfection area, thereby adjusting the movement route and / or disinfection method of the disinfection robot 110 to ensure the disinfection efficiency of each sub-disinfection area.

[0068] Preferably, the central server 130 can collect environmental information such as changes in personnel activity and / or equipment layout in the disinfection area in real time through the information acquisition device 120. Preferably, when equipment such as a CT scanner in the first disinfection area using irradiation disinfection is removed and personnel activity exists in the disinfection area, the central server 130 reclassifies the first disinfection area into a second disinfection area using atomization disinfection. Preferably, the central server 130 updates the movement map of the disinfection robot 110 according to the reclassification of the sub-disinfection areas. Specifically, the central server 130 removes the disinfection area from the movement map of the first disinfection robot and adds it to the movement map of the second disinfection robot, so that the second disinfection robot replaces the first disinfection robot to enter the disinfection area to perform atomization disinfection. This realizes real-time adjustment of the movement route of the disinfection robot 110 and the disinfection method adapted to the sub-disinfection area, avoiding the problem that the disinfection robot 110 cannot adjust its disinfection method when the disinfection method adapted to the sub-disinfection area changes due to the pre-set walking path of the disinfection robot 110.

[0069] Preferably, the disinfection robot 110 uploads its status information to the central server 130, enabling the central server 130 to obtain the task execution capabilities of each disinfection robot 110 when generating a disinfection task. This allows the central server 130 to combine the movement routes of the disinfection robots 110 in the disinfection area, thereby improving the utilization efficiency of the disinfection robots 110. Preferably, the task execution capabilities of the disinfection robot 110 can be its movable distance and the volume of space it can disinfect.

[0070] Preferably, the processing module 111 controls the movement of the movement module 114 according to the movement route of the disinfection robot 110 in the disinfection task. Preferably, the disinfection robot 110 is also equipped with a positioning module electrically connected to the processing module 111. Preferably, the positioning module of the disinfection robot 110 can be connected to the hospital's existing indoor positioning system. Preferably, the processing module 111 pre-stores the hospital's architectural drawings, and the processing module 111 can obtain the location of the disinfection robot 110 in the hospital through the positioning module. Preferably, the movement module 114 can be a movement mechanism such as tires or tracks configured on the disinfection robot 110. After receiving a disinfection task, the processing module 111 can control the movement of the movement module 114 according to the location of the disinfection robot 110 in the hospital and the movement route in the disinfection task, so that the disinfection robot 110 enters each sub-disinfection area for disinfection. Preferably, the movement route of the disinfection robot 110 includes at least a first movement route for the disinfection robot 110 to move between sub-disinfection areas and a second movement route for the disinfection robot 110 to move within a sub-disinfection area. Preferably, the first movement route can be a corridor, elevator, or other passageway that the disinfection robot 110 needs to traverse when moving between sub-disinfection areas. Preferably, the second movement route can be a movement route by which the disinfection robot 110 ensures that the disinfection area covers the disinfection area space within the sub-disinfection area.

[0071] Preferably, when the disinfection robot 110 enters or exits the sub-disinfection area, the processing module 111 controls the start and stop of the disinfection module 113, thereby ensuring that the disinfection robot 110 disinfects the sub-disinfection area, while avoiding the waste of energy or disinfectant caused by the disinfection robot 110 releasing disinfectant or emitting sterilization light when moving between sub-disinfection areas, as well as the potential damage to the human body or equipment caused by disinfectant or sterilization light.

[0072] Preferably, the central server 130 generates disinfection tasks based on the status information of the disinfection robot 110 and the sub-disinfection areas, so that the central server 130 can set up combined disinfection tasks based on the task execution capabilities of the disinfection robot 110. That is, when generating disinfection tasks, the central server 130 allocates the disinfection areas to be handled by each disinfection robot 110, thereby reducing the disinfection time.

[0073] Example 2

[0074] This embodiment is a further improvement on embodiment 1, and repeated content will not be described again.

[0075] The intelligent disinfection system 100 provided in Example 1 relies on image acquisition devices such as cameras to obtain information when setting the movement routes of each disinfection robot 110 and judging the completion status of the disinfection work of the disinfection robot 110. If images of the disinfection area are obtained through monitoring cameras, a large number of cameras need to be set up to eliminate blind spots, which undoubtedly leads to high installation costs. Due to the limited field of view of monitoring cameras, the images of the disinfection area they acquire are often tilted, requiring image processing to obtain spatial information of the disinfection area. Errors are easily introduced during the processing, causing the disinfection area of ​​the disinfection robot 110 to differ from the actual area to be disinfected, thus affecting the disinfection effect.

[0076] Preferably, the intelligent disinfection system 100 provided in this embodiment may include a plurality of disinfection robots 110, an information collection device 120, and a central server 130. Preferably, the information collection device 120 may be mounted on the disinfection robot 110. Preferably, the information collection device 120 may also be mounted on a mobile platform with inspection functions, such as a cleaning robot or a triage robot. The information collection device 120 may include devices such as cameras and lidar. Preferably, the information collection device 120 may be connected to the processing module 111 of the disinfection robot 110. Preferably, the disinfection robot 110 may include a first disinfection robot using irradiation disinfection and a second disinfection robot using atomization disinfection.

[0077] Preferably, the disinfection robot 110 in this embodiment may include a first disinfection robot or a second disinfection robot equipped with an information collection device 120. Preferably, the first or second disinfection robot equipped with the information collection device 120 is the main disinfection robot, and the first or second disinfection robot without the information collection device 120 is the auxiliary disinfection robot. Preferably, the communication module 112 of the main disinfection robot establishes communication connections with the communication modules 112 of the other auxiliary disinfection robots, so that the main disinfection robot and the other auxiliary disinfection robots can transmit information to each other.

[0078] Preferably, when disinfecting high-risk locations such as hospitals where pathogens exist, the central server 130 can obtain information about the areas to be disinfected through architectural drawings, layout drawings, and other information to set the inspection route for the main disinfection robot. Preferably, the main disinfection robot moves along the inspection route to obtain environmental changes in each disinfection area and detects the disinfection effect of each disinfection area.

[0079] Preferably, the main disinfection robot acquires environmental information of each disinfection area through the configured information collection device 120 and transmits the environmental information to the central server 130. Preferably, when the central server 130 detects changes in environmental information such as facility distribution and personnel activities in the disinfection area, it updates the division of the sub-disinfection areas.

[0080] For example, when a hospital temporarily places equipment and supplies in a room due to department relocation or renovation, the main disinfection robot can detect changes in the distribution of facilities in the room where the equipment and supplies are temporarily placed during the inspection process and upload these changes to the central server 130 to change the disinfection method of the room where the equipment and supplies are temporarily placed.

[0081] Preferably, when a room using atomized disinfection is used as a temporary warehouse to store medical supplies, the main disinfection robot can acquire this change through a camera during the inspection process. Preferably, after the processing module 111 of the main disinfection robot acquires the environmental changes of the room through the camera, it can update the disinfection method used in the room, and the main disinfection robot uploads the update result to the central server 130, so that the central server 130 updates the division of sub-disinfection areas.

[0082] Preferably, when the main disinfection robot learns that a room using atomized disinfection is being used as a temporary warehouse to store medical supplies, the main disinfection robot updates the disinfection method of the room to irradiation disinfection and sends instructions to the auxiliary disinfection robot using irradiation disinfection, so that the first disinfection robot, which is not equipped with an information collection device 120, disinfects the room used as a temporary warehouse.

[0083] Preferably, the main disinfection robot is equipped with a sampling module. Preferably, after the auxiliary disinfection robot completes its received disinfection task, the main disinfection robot can sample the gas and / or object surface of the area disinfected by the auxiliary disinfection robot through the sampling module. Preferably, the main disinfection robot can collect the gas in the area disinfected by the auxiliary disinfection robot through a gas collecting bottle or by wiping the object surface with a sterile cloth. Preferably, after sampling, the main disinfection robot can transport the sample to a testing laboratory to test the bacterial survival rate in the sample to determine the effectiveness of the area disinfected by the auxiliary disinfection robot. Preferably, when the disinfection effect is unsatisfactory, the central server 130 can increase the disinfection frequency of the unsatisfactory area to improve the disinfection effect. Preferably, when the disinfection effect is unsatisfactory, it indicates that the bacteria in the area are multiplying rapidly or that there are many bacteria in the area. The central server 130 can designate the area as a hot spot area and disinfect it with a higher level of disinfection. Preferably, the central server 130 can focus on disinfecting the hot spot area by spraying a higher concentration of disinfectant, irradiating it with a higher intensity sterilization light, or increasing the disinfection frequency.

[0084] Preferably, the main disinfection robot can also be equipped with a gas sensor to detect the concentration of disinfectant in the disinfection area. Preferably, in the second disinfection area using atomized disinfection, the main disinfection robot and multiple auxiliary disinfection robots perform disinfection simultaneously.

[0085] Preferably, the main disinfection robot can cooperate with multiple auxiliary disinfection robots to disinfect areas using the same disinfection method. The main disinfection robot can check the disinfection effect. If the disinfection effect is unqualified, the main disinfection robot can re-disinfect the area with unqualified disinfection effect through itself or other auxiliary disinfection robots.

[0086] For example, in a hospital lobby, several second disinfection robots perform atomized disinfection of the lobby. Among these second disinfection robots, one can be a main disinfection robot equipped with an information acquisition device 120 and a gas sensor, while the other second disinfection robots without the information acquisition device 120 and gas sensors are auxiliary disinfection robots. Preferably, the communication module 112 of the main disinfection robot can establish communication connections with the communication modules 112 of each of the other auxiliary disinfection robots, allowing the processing module 111 of the main disinfection robot to transmit information to each other. Preferably, for ease of description, in the following description of this embodiment, the processing module 111 of the main disinfection robot will be referred to as the first processing module, and the processing module 111 of the auxiliary disinfection robots will be referred to as the second processing module.

[0087] Preferably, the first processing module can acquire environmental information of the hospital lobby through the information acquisition device 120, preferably the building area and layout. Preferably, the information acquisition device 120 acquires the environmental information of the hospital lobby and transmits it to the first processing module. The first processing module can then divide the area of ​​the hospital lobby requiring disinfection into several disinfection spaces based on the building area and layout of the lobby, as well as the number of second disinfection robots in the lobby. Preferably, after acquiring the environmental information of the hospital lobby, the first processing module can divide the hospital lobby into several disinfection spaces and allocate these spaces to the respective second processing modules within the hospital lobby.

[0088] Preferably, the first processing module allocates the disinfection space to the main disinfection robot and other auxiliary disinfection robots. Preferably, the first processing module can divide the disinfection space according to the number of second disinfection robots, such that each second disinfection robot is responsible for at least two disinfection spaces.

[0089] Preferably, after the second processing module controls the disinfection module 113 and the moving module 114 to work so that the auxiliary disinfection robot completes the disinfection of the allocated disinfection space, the second processing module 1 sends a completion signal to the first processing module, so that the first processing module controls the main disinfection robot to check the disinfection effect of the auxiliary disinfection robot.

[0090] Preferably, after receiving the completion signal, the first processing module controls the main disinfection robot's movement module 114 to move to the disinfection space corresponding to the completion signal. The first processing module can determine the concentration of disinfectant in the disinfection space using a gas sensor, thereby determining whether the disinfection effect is qualified. Preferably, the gas sensor transmits the disinfectant concentration to the first processing module, which can determine whether the disinfection effect is qualified by comparing the concentration detected by the gas sensor with a preset concentration threshold. Preferably, when the disinfectant concentration in the disinfection space is lower than the threshold, the first processing module can determine that the disinfection effect is unqualified. In this case, the first processing module can control the disinfection module 113 and the movement module 114 to make the main disinfection robot spray disinfectant in the disinfection space where the disinfection effect is unqualified until the disinfectant concentration in the disinfection space exceeds the threshold.

[0091] Preferably, the processing module 111 of the disinfection robot 110 can be configured with three working modes, including: a first working mode in which the processing module 111 controls the operation of the disinfection module 113 and the movement module 114 to enable the disinfection robot 110 to perform atomized disinfection on the allocated disinfection space; a second working mode in which the processing module 111 controls the operation of the sampling module and the movement module 114 to enable the disinfection robot 110 to detect the concentration of disinfectant in the disinfection space; and a third working mode in which the processing module 111 stops the operation of the disinfection module 113, the movement module 114, etc., so that the disinfection robot 110 is in a standby state. Preferably, the first processing module can be configured with the first working mode, the second working mode, and the third working mode. Preferably, the second processing module is configured with only the first working mode and the third working mode.

[0092] Preferably, after the first processing module completes the division of the disinfection space, it enters the first working mode to control the main disinfection robot to disinfect the hospital lobby. After receiving the disinfection space divided by the first processing module, the second processing module enters the first working mode to control the auxiliary disinfection robot to disinfect the corresponding disinfection space.

[0093] Preferably, the second processing module sends a completion signal to the first processing module after controlling the auxiliary disinfection robot to complete the disinfection of a disinfection space. Preferably, upon receiving the completion signal, the first processing module switches its operating mode from the first operating mode to the second operating mode, causing the main robot to move to the disinfection space handled by other auxiliary disinfection robots to detect the disinfectant concentration and determine whether the disinfection effect is qualified. Preferably, when the disinfection effect is unqualified, the first processing module switches from the second operating mode to the first operating mode, causing the main disinfection robot to disinfect the disinfection space where the disinfection effect is unqualified.

[0094] Preferably, the preset concentration threshold can be 90%. When the second processing module sends a completion signal to the first processing module, the first processing module switches from the first working mode to the second working mode, so that the main robot moves to the disinfection space that the auxiliary disinfection robot that sent the completion signal is responsible for in order to detect the concentration of disinfectant in the disinfection space.

[0095] Preferably, the first processing module obtains the disinfectant concentration in the disinfection space through the sampling module. When the disinfectant concentration is not lower than 90%, the first processing module can determine that the disinfection effect of the disinfection space is qualified. When the disinfectant concentration is lower than 90%, the first processing module can determine that the disinfection effect of the disinfection space is unqualified, and the first processing module switches from the second working mode to the first working mode, so that the main disinfection robot disinfects the disinfection space with unqualified disinfection effect until the disinfectant concentration in the disinfection space exceeds 90%.

[0096] Preferably, after the second processing module controls the auxiliary disinfection robot to complete the disinfection of the assigned disinfection space, it enters the third working mode, putting the auxiliary disinfection robot into a standby state. Preferably, when there is an auxiliary disinfection robot in standby mode and the first processing module has two or more disinfection spaces to be inspected, the first processing module maintains the second working mode to check the disinfectant concentration of the disinfection space and determine the disinfection effect. Preferably, when the disinfection effect is unqualified, the first processing module sends an instruction to the second processing module in the third working mode, causing it to control the auxiliary disinfection robot to disinfect the disinfection space with unqualified disinfection effect, while the first processing module maintains the second working mode to inspect the other disinfection spaces to be inspected.

[0097] Preferably, the first processing module can divide sub-disinfection areas using the same disinfection method into several disinfection spaces and allocate them to the main disinfection robot and other auxiliary disinfection robots, thereby shortening the time required for a single disinfection of the disinfection area and improving disinfection efficiency. Preferably, when the second processing module is in the first working mode to control the auxiliary disinfection robots to disinfect the disinfection spaces, the first processing module can control the main disinfection robot to disinfect the disinfection spaces that do not meet the disinfection requirements; when the second processing module is in the third working mode and the auxiliary disinfection robots are in standby mode, the first processing module can generate a disinfection command to disinfect the disinfection spaces that do not meet the disinfection requirements and send it to the second processing module of the auxiliary disinfection robots in the standby state, so that the second processing module in the third working mode enters the first working mode to control the auxiliary disinfection robots to disinfect the disinfection spaces that do not meet the disinfection requirements, thereby improving the utilization efficiency of the disinfection robots.

[0098] According to a preferred embodiment, the central server 130 can determine the location of key disinfection areas by measuring the relative time taken by the main disinfection robot to disinfect within the disinfection area. Preferably, the relative time taken by the main disinfection robot to disinfect within the disinfection area is the ratio of the total time taken by the main disinfection robot to disinfect within the disinfection area (either by itself or by controlling the auxiliary disinfection robots) to the area of ​​the disinfection area; that is, the time taken by the main disinfection robot to disinfect a unit area within the disinfection area using itself or by the auxiliary disinfection robots. Preferably, the longer the relative time taken by the main disinfection robot to disinfect within the disinfection area, the more focused the disinfection needs to be. The central server 130 can then disinfect key areas by adding more disinfection robots or increasing the disinfection frequency, thereby achieving efficient, economical, and accurate disinfection.

[0099] Preferably, for disinfection areas using atomized disinfection, especially areas with high concentrations of environmental disinfectant, after the auxiliary disinfection robot completes disinfection of the assigned disinfection space, the second processing module controls the auxiliary disinfection robot to move to the boundary of the disinfection area, so that personnel can intuitively confirm the concentration of disinfectant in the area and avoid exposure to harmful disinfectant.
