Methods, systems, and servers for indoor operation monitoring of cleaning devices

A system for indoor operation monitoring of a cleaning device, wherein the system includes a cleaning device, a server connected to the cleaning device via a network, and a monitoring terminal for displaying a monitoring interface;

• the cleaning device is configured to collect a set of positioning data based on a data collection period and send the set of positioning data to the server via the network;
• the server is configured to:
• generate a work region map;
• form a monitoring map based on location fingerprints taken from a work region in the work region map;
• determine working trajectory points of the cleaning device based on the set of positioning data sent by the cleaning device;
• obtain a monitoring task region through the monitoring terminal;
• determine, based on the monitoring map, a monitoring region map corresponding to the monitoring task region, match the working trajectory points with the monitoring region map, and determine cumulative trajectory points within the monitoring task region;
• and
• in response to determining that a count of the cumulative trajectory points and a distribution situation of the cumulative trajectory points satisfy a preset update condition, send a display update instruction to the monitoring terminal;
• and
• the monitoring terminal is configured to update a display feature on the monitoring interface based on the display update instruction sent by the server.
