Problems solved by technology

Due to the limitations of the WIFI module CPU processing capacity, data transmission rate and memory, usually the WIFI module cannot transmit complete map data to the cloud at one time, but needs to be completed in batches or compressed before transmission
If the method of batch transmission is adopted, when the network condition is not good, it is easy to lose the transmitted data, resulting in incomplete data obtained by the cloud; and with the continuous increase of transmitted data, the storage capacity of the sweeping robot is limited. , a large amount of data transmission can no longer be achieved by simple compressed upload

Embodiment Construction

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the connection can be used for both fixing function and circuit communication function.

[0037] It is to be understood that the terms "length", "width", "top", "bottom", "front"...

Abstract

The invention provides a map data transmission method and device, and the method comprises the steps: obtaining real-time map data, storing the real-time map data in a cache region of a WiFi module group, and enabling the cache region to comprise a volatile cache region and a nonvolatile cache region; controlling the WiFi module to send the real-time map data to a cloud end; visual images or videos and track data of the current position are obtained, whether the real-time map data are accurate or not is judged, if not, the real-time map data are corrected to obtain corrected map data, and thecorrected map data are stored in a cache region of the WiFi module; and controlling the WiFi module to send the corrected map data to the cloud. The non-volatile cache region is arranged on the WiFi module, the data transmission mode is improved, and it is ensured that the terminal obtains a complete and accurate map.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a map transmission method and device. Background technique [0002] At present, household sweeping robots are becoming more and more popular, including laser robots, vision robots and gyroscope robots. Laser robots can obtain accurate sweeping maps, but the cost is relatively high. Obtaining accurate sweeping maps facilitates the subsequent designation of sweeping locations, setting of virtual walls, designation of cleaning areas, and designation of areas where cleaning is prohibited. [0003] The wifi transmission module of the sweeping robot in the prior art has a storage function, which can be used to store a part of the sweeping record map. The stored data can be uploaded to the cloud through the wifi transmission module, and then the user can download the sweeping record map from the cloud through the APP for viewing . [0004] However, when the sweeping robot skids or stop...
