SYSTEM AND METHOD FOR DETECTING POSITION DEVIATION OF INVENTORY HOLDER BASED ON FEATURE INFORMATION GRAPHS

摘要

The present invention discloses a AP switching method for mobile robots based on path setting, including the following steps: install APs in the application environments of mobile robots; control the mobile robots to move along established routes, record the signal strengths of each of the APs on each of the paths of the mobile robots, and determine the AP with the strongest signal strength on each path; configure the MAC addresses of the APs to be connected on each path whereon the mobile robots will move; the mobile robots monitor continuously whether the AP that is connected at the moment coincides with the AP configured for the current path, if not, then switch to the configured AP directly. The present invention can avoid effectively the problem of switching APs excessively frequently, the method is simple and effective, without the need for setting thresholds for signal strengths, and it can decrease uncertainty effectively, which is valuable in the application environments of mobile robots.
