The intelligent disinfection method is simple and has strong practicability.
Meanwhile, the intelligent disinfection method is applied to the sweeper, multiple indoor areas can be sterilized and disinfected through autonomous movement of the sweeper, and the defects that an original mercury lamp is large in size, fixed in installation position and inconvenient to move are overcome. The intelligent disinfection method of the embodiment has less manual participation and high degree of autonomy.
In this embodiment, a miniaturized UVC ultraviolet LED lamp is used as the sterilization tool.
Further, the environmental data includes a surface area of the target disinfection zone; the step S1 of acquiring environmental data of the target disinfection area includes:

In this embodiment, the sweeper is after receiving the disinfection instruction, disinfects and sterilizes the inside appointed area of sweeper earlier, and the target disinfection area in the external environment is disinfected and sterilized again after accomplishing. The sequence of the internal disinfection and the external disinfection of the sweeper can avoid bacteria in the sweeper from coming out of the sweeper and polluting the external environment and causing cross contamination with the external environment in the moving process of the sweeper.
Further, before the step S1 of acquiring the environmental data of the target disinfection area, the method includes:
s04: dividing the external space into a plurality of disinfection areas;
s05: receiving a disinfection request of a client, and taking at least one disinfection area indicated by the disinfection request as the target disinfection area; wherein, at least one disinfection area indicated by the disinfection request is determined according to selection of a plurality of disinfection areas displayed by a client by a user.
In step S04, the exterior space refers to an indoor space where the sweeper is located. The floor sweeping machine divides the indoor space into a plurality of disinfection areas and records the disinfection areas.
In step S05, the interaction information between the sweeper and the user is controlled by the bound client, and the sweeper performs the disinfection operation according to the disinfection request received from the client. In the intelligent disinfection method, the user defines the mobile disinfection mode of the sweeper through the client. In the invention, the mobile disinfection mode of the sweeper comprises a general mode and a custom mode. When a user selects a general mode on the client for disinfection, the client returns a disinfection request corresponding to the general mode to the sweeper, and the sweeper takes a default selected disinfection area as a target disinfection area according to the indication of the disinfection request and disinfects the target disinfection area. In general, the sweeper defaults to a selected decontamination area as all of the decontamination areas. When a user selects a custom mode on a client for disinfection, the user can select a plurality of disinfection areas on the client as target disinfection areas of the disinfection work, a disinfection request is formed and sent to the sweeper, and the sweeper reaches the target disinfection areas selected by the user according to the indication of the disinfection request for disinfection work.
Further, after step S05 of receiving a sterilization request from the client, and regarding at least one sterilization area indicated by the sterilization request as a target sterilization area, the method includes:
s06: and sequentially reaching the target disinfection area according to the disinfection path indicated by the disinfection request.
In step S06, the user selects the disinfection sequence of the target disinfection area, i.e., the disinfection path of the sweeper, on the client.
In this embodiment, the sweeper sterilizes at least one target sterilization area designated by the user according to the sterilization path indicated on the sterilization request returned by the client. Specifically, when a user selects a general mode on the client for disinfection, the client returns a disinfection request corresponding to the general mode to the sweeper, and the sweeper disinfects a target disinfection area selected by default by the sweeper according to a default disinfection path indicated by the disinfection request. When a user selects a custom mode on a client for disinfection, the user can select a plurality of disinfection areas on the client as target disinfection areas, select the disinfection sequence of the target disinfection areas, form disinfection paths to be recorded in a disinfection request, the client sends the disinfection request to a sweeper, and the sweeper conducts disinfection work on the target disinfection area designated by the user according to the disinfection path selected by the user and indicated by the disinfection request.
Still further, in other embodiments, the intelligent disinfection method of the present invention further comprises: and disinfecting the target disinfection area according to the disinfection power indicated by the disinfection request. For example, when the user selects a general mode on the client for disinfection, the client returns a disinfection request corresponding to the general mode to the sweeper, and the sweeper disinfects a target disinfection area selected by default by the sweeper according to the default disinfection power indicated by the disinfection request. When a user selects a custom mode on a client for disinfection, the user can select corresponding disinfection power for several selected target disinfection areas on the client respectively, and form a disinfection request to be sent to the sweeper through the client, and the sweeper disinfects the several target disinfection areas according to the disinfection power corresponding to the selected target disinfection areas respectively according to the indication of the disinfection request.
