Claim 16:
17. A mower fleet management system, comprising:
a mower fleet comprising a plurality of mowers, wherein each of the plurality of mowers comprises an on-board communication module and an on-board positioning and navigation hardware; and
a mower fleet management device comprising:
a map loading module configured to acquire a map of a working land for use by the on-board positioning and navigation hardware;
a control terminal communication module configured to communicate with the on-board communication modules to acquire status information of the mowers or transmit a control command to the mowers, wherein the status information comprises at least one of charge amount of battery, speed and mowing widths of the plurality of mowers; and
a working region assigning module configured to assign a working region to each of the plurality of mowers according to the status information and the map; wherein
the on-board positioning and navigation hardware of each of the plurality of mowers is configured to guide each mower to work in the working region assigned by the working region assigning module;
the working region assigning module comprises a working area estimation unit and a path generation unit, wherein the working area estimation unit is configured to estimate a working area value of each of the mowers according to the status information, and the path generation unit is configured to generate a working path according to the estimated working area value and the map of the working land; when a sum of the estimated working area values of all of the mowers is less than an area value of the working land, the working region assigning module transmits a prompt message;, wherein, an estimation equation for the working area is:

Simax=Bi*SOCi*Ki, or

Simax=(Bi−Bimin−Biback)*SOCi*Ki, or

Simax=(Bi−Bimin−Biback)*SOCi*Ki*(1−Fi),, wherein Simax is an estimated working area of an ith mower, Bi is a current battery percentage of the battery of the ith mower, and Ki is a ratio of a mowing area to power consumption of the ith mower, SOCi is a full charge of a battery of the ith mower, Bimin is a preset minimum battery percentage for the battery of the ith mower, Biback is a preset back battery percentage according to a distance between a position of the mower when work completed and a starting point, Fi is a preset re-mowing rate for the ith mower.
