  • Publication number: 20240016089
    Abstract: A combine is provided with a control device configured to function as a route generation unit, a position setting unit, a mid-work route generation unit, or a self-driving control unit. The route generation unit generates a travel route by combining a plurality of routes for an unreaped region in a field. To perform mid-work corresponding to the work amount of reaping traveling at a preset mid-work position, the position setting unit sets an interruption position at which automatic reaping traveling is interrupted to the end point of a predetermined interruption route based on the work amount. To perform the mid-work, the mid-work route generation unit generates a mid-work route extending from the interruption position to the mid-work position. The self-driving control unit controls traveling and reaping based on the travel or mid-work route.

    Abstract: A thermoelectric generation system is provided with: a thermoelectric element; a heating unit; a cooling unit; a heat transfer unit; a pressure gauge; a first valve; and a control unit. The thermoelectric element uses a temperature difference to generate power. The heating unit has a first heat medium path through which a heat medium passes, and heats the thermoelectric element by means of the heat of the heat medium. The cooling unit cools the thermoelectric element. The heat transfer unit has a second heat medium path through which the heat medium passes and which is connected to the first heat medium path, and heats, by using a heat source, the heat medium reduced in temperature as a result of heating the thermoelectric element. The pressure gauge detects the rise or fall of a value (pressure of heat medium) in accordance with the temperature of the heat source.
