BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Various other advantages and benefits will become apparent to those skilled in the art upon reading the detailed description of the preferred embodiment below. The accompanying drawings are for illustration purposes only and are not to be considered as limiting the present invention. Throughout the drawings, the same reference figures denote the same components. In the drawings:

[0037] Figure 1 The schematic diagram of the structure of the ultraviolet disinfection system in the embodiment of the present invention is shown. DETAILED DESCRIPTION

[0038] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0039] The embodiment of the present invention provides an ultraviolet disinfection system, such as Figure 1 Shown, including:

[0040] Ultraviolet lamp 101, used to disinfect the environment within a preset range;

[0041] A mobile trolley 102 is used to support the ultraviolet lamp 101;

[0042] The control circuit 103 is used to control the on and off of the ultraviolet lamp 101;

[0043] The infrared ranging module 104 is provided on the four edges of the mobile trolley base and is used to monitor whether there is a person approaching within a preset distance of the mobile trolley 102;

[0044] When the infrared ranging module 104 detects that a person is approaching within a preset distance, the control circuit 103 controls the ultraviolet lamp 101 to be turned off.

[0045] In a specific embodiment, the free movement of the mobile car 102 can be remotely controlled by a remote controller. Viruses and bacteria can be disinfected at close range in the area it passes through.

[0046] To improve the disinfection safety of the system, the UV lamp 101 can be controlled to be turned off when a person approaches, thereby ensuring the safety of the person. The infrared ranging module 104 monitors whether there are people within a preset space. For example, the monitoring distance limit can be set to 1m. When a person reaches 1m from the mobile cart 102, the control circuit 103 controls the UV lamp 101 to be turned off, effectively protecting the health of the person.

[0047] After the ultraviolet lamp 101 is controlled to be turned off, it is necessary to control the ultraviolet lamp 101 to be turned on again after the personnel leave.

[0048] Specifically, when the infrared ranging module 104 detects that a person has left the preset distance, the control circuit 103 controls the ultraviolet lamp 101 to turn on after a preset time delay;

[0049] If the infrared ranging module 104 detects a person approaching within the preset distance again within the preset time, the control circuit 103 controls the ultraviolet lamp 101 to turn off the function of delaying the start for the preset time, and waits for the person to leave before controlling the ultraviolet lamp 101 to turn on after the preset time.

[0050] By setting a delay time for turning on the UV lamp 101, the UV lamp 101 is turned on and off repeatedly to avoid the need for people to come and go during the delay time, which would affect the life of the UV lamp. Therefore, the UV lamp 101 is turned on only when people do not enter the area, ensuring safety while also protecting the life of the UV lamp 101.

[0051] In a specific embodiment, the system further includes: a route guidance module, which is provided on the mobile cart 102 and is used to guide the mobile cart 102 to move in the target room so that each location in the target room is disinfected.

[0052] The route guidance module can guide the mobile cart 102 to perform disinfection along the route. Since the furnishings in each room are different, different guidance routes need to be used for different rooms.

[0053] Specifically, a target route is generated based on the layout of items in the target room;

[0054] Based on the target route, the mobile car 102 is directed to move in the target room.

[0055] The target route is determined by the placement of items in the target room. This target route includes not only the route direction and location, but also the duration of stay at different locations. For example, for locations with a large number of items, you can choose to stay longer, while for locations with fewer items, you can move and disinfect directly without stopping.

[0056] The control of the ultraviolet lamp 101 for ensuring the safety of personnel is performed when the personnel actively approach the mobile vehicle 102. The following describes the situation in which the mobile vehicle 102 actively approaches the personnel:

[0057] The route guidance module is used to guide the mobile car to move in the target room, and when the mobile car is about to move to a preset distance from a person according to the target route, control the mobile car 102 to pause or change the moving route.

[0058] By controlling the mobile car 102 to pause its movement, on the one hand, disinfection can be continued, and on the other hand, the safety of personnel can be guaranteed. Changing the movement route can also achieve uninterrupted disinfection and ensure personnel safety.

[0059] Among them, the method of changing the moving route can be to find the target position on the target route when the current monitoring mobile car 102 is at a preset distance from the personnel. The distance between the target position and the personnel is greater than the preset distance. At the same time, the target position is closest to the current position. By controlling the mobile car 102 to move to the target position and avoiding the personnel during the movement, the area where the personnel is located is disinfected again after the personnel leave, which not only ensures the safety of the personnel, but also improves the efficiency of disinfection.

[0060] In an optional embodiment, the system further includes: a first timer, configured to first time the duration of the UV lamp being on;

[0061] a processor, connected to the first timer, and configured to generate a prompt message when the first timer exceeds a life span;

[0062] The display screen displays based on the prompt information.

[0063] By timing the usage time of the ultraviolet lamp 101, a prompt is given when the corresponding life span is exceeded. For example, if the service life of the lamp is 1000 hours, when the usage time of the lamp reaches 1000 hours as measured by the first timer, a prompt message is generated by the processor and displayed on the display screen. To attract attention, a buzzer is also provided and connected to the processor so that the buzzer emits a continuous alarm sound based on the prompt message to remind staff to replace the lamp in time.

[0064] In an optional embodiment, the system further includes:

[0065] A second timer is used to measure the duration of the UV lamp 101 being turned on for one disinfection operation;

[0066] The second timer is connected to the processor, which is connected to the control circuit. The processor is used to control the UV lamp 101 to be turned off through the control circuit 103 when the second timer reaches the preset disinfection time. Of course, the second timer starts timing when the UV lamp 101 is turned on.

[0067] Through the timing of the second timer, it can be automatically opened and closed during the disinfection process without human participation, which can be automated and free the hands of the staff.

[0068] In an optional embodiment, the system further includes:

[0069] Bluetooth module, connected to the door lock of the target room;

[0070] After the ultraviolet lamp 101 is turned off, a door opening instruction is sent to the door lock through the Bluetooth module, so that the mobile car 102 leaves the target room according to the guidance route and automatically returns to the preset position.

[0071] By setting up a Bluetooth module, the ultraviolet lamp 101 is linked to the door lock. When entering or leaving the target room, the door lock is opened and closed to control the opening and closing of the door, so that the user can enter or leave the target room smoothly. At the same time, the ultraviolet lamp 101 can be returned to the preset position after leaving the target room according to the guidance route without human intervention, thus saving labor and time.
