1. An autonomous work system that controls an autonomous work machine that detects a magnetic field of an area signal generated by energization to an area wire disposed on an outer periphery of a work area, specifies a boundary of the work area based on the magnetic field, and works autonomously in the work area, the autonomous work system comprising:
a memory configured to store position information of a plurality of the work areas;
a processor circuit executing instructions that, when executed, cause the processor circuit to set, based on the position information, different energization modes, in a case where a plurality of adjacent work areas at adjacent positions is present, such that area signals corresponding to the plurality of adjacent work areas are not identical mutually, wherein in a case where the plurality of adjacent work areas at adjacent positions is present and respective autonomous work machines that work in the plurality of adjacent work areas do not overlap in work schedule, the processor is configured to set a common energization mode to the plurality of adjacent work areas; and
a station electronic controller configured to energize, based on the different energization modes, the area wires disposed on the respective outer peripheries of the plurality of adjacent work areas, wherein the station electronic controller is configured to energize, based on the common energization mode, the area wires disposed on the respective outer peripheries of the plurality of adjacent work areas in a case where the common energization mode is set by the processor circuit,
wherein every certain period, the station electronic controller transmits, to the processor circuit, the position information of the work area corresponding to the area wire in energization and an identification pattern of the area signal corresponding to an energization mode, and
the instructions further cause the processor circuit to:
store, in the memory, the position information and the identification pattern, and
delete, from the memory, in a case where the position information and the identification pattern are not received from the station electronic controller after an elapse of the certain period, the position information and the identification pattern.
