Background technique:

      At present, in the way of confirming the operation boundary of the smart lawn mower, the more mainstream is to adopt the method of electrifying the line or based on the GPS. However, the former requires accurate wiring operations for the entire work area. If there are multiple independent small work areas in the mowing work area, it is impossible to use the power-on fence for boundary identification. Although the use of GPS positioning information for boundary identification can solve the defect of the power-on line to a certain extent, the influence of the complex environment on the GPS signal makes it impossible to rely on the GPS for accurate boundary positioning.

      Technical realization elements:

      In order to solve the shortcomings and deficiencies in the prior art, the present invention proposes a work navigation method for smart lawn mowers, which can adaptively switch the navigation mode according to the current navigation signal strength in the work area, thereby improving intelligence The accuracy of the positioning of the lawn mower in the work area.
