Abstract

A control apparatus 13 outputs an order signal to order supply apparatuses 12-1 through 12-N to perform supply of a signal in a contactless manner at a respectively different timing. The control apparatus 13 determines that a moving apparatus 11 is stopped at the position of the supply apparatus 12 being the output destination of the signal output order, when a wireless signal is received from the moving apparatus 11 within a certain period of time after outputting the order signal. Then, the supply apparatus 12 at the position at which the moving apparatus 11 is ordered to start supplying a signal.

Claims

1. A control apparatus configured to control a plurality of supply apparatuses that supply a signal to a moving apparatus in a contactless manner, comprising:

a wireless unit configured to perform transmission/reception of a wireless signal; and

a control unit configured to output an order signal to order a plurality of supply apparatuses to perform supply of a signal in a contactless manner at a respectively different timing, and also to determine that the moving apparatus is stopped at a position of the supply apparatus being an output destination of the order signal, when a wireless signal is received in the wireless unit from the moving apparatus within a certain period of time after outputting the order signal.

2. The control apparatus according to claim 1, wherein

the supply apparatus is an apparatus that supplies electricity to the moving apparatus in a contactless manner, and

the control unit outputs a signal to the supply apparatus being an output destination of the order signal to order start of supply or electricity, when a wireless signal is received in the wireless unit from the moving apparatus within a certain period of time after outputting the order signal.

3. The control apparatus according to claim 1, wherein

the control unit makes a first order signal to order a first supply apparatus among the plurality of supply apparatuses to supply a signal valid for a certain period of time, to make the first supply apparatus supply a signal in a contactless manner, and after that, making the first order signal invalid, and makes a second order signal to order a second supply apparatus to supply a signal valid for a certain period of time, to make the second supply apparatus supply a signal in a contactless manner, and after that, makes the second order signal invalid.

4. The control apparatus according to claim 1, wherein

the control unit transmits the order signal by power line communications to the plurality of supply apparatuses.

5. A control method to control a plurality of supply apparatuses that supply a signal to a moving apparatus in a contactless manner, comprising:

outputting an order signal to order a plurality of supply apparatuses to perform supply of a signal in a contactless manner at a respectively different timing, and also determining that the moving apparatus is stopped at a position of the supply apparatus being an output destination of the order signal, when a wireless signal is received from the moving apparatus within a certain period of time after outputting the order signal.

6. The control method of supply apparatuses according to claim 5, wherein

the supply apparatus is an apparatus that supplies electricity to the moving apparatus in a contactless manner, and

a signal is output to the supply apparatus being an output destination of the order signal to order start of supply of electricity, when a wireless signal is received from the moving apparatus within a certain period of time after outputting the order signal.

7. The control method of supply apparatuses according to claim 5, wherein

a first order signal to order a first supply apparatus among the plurality of supply apparatuses to supply a signal is made valid for a certain period of time, to make the first supply apparatus supply a signal in a contactless manner, and after that, the first order signal is made invalid, and a second order signal to order a second supply apparatus to supply a signal is made valid for a certain period of time, to make the second supply apparatus supply a signal, and after that, the second order signal is made invalid.

8. A supply system comprising:

a plurality of supply apparatuses that supply a signal to a moving apparatus in a contactless manner; and

a control apparatus comprising a wireless unit configured to perform transmission/reception of a wireless signal; and

a control unit configured to output an order signal to order a plurality of supply apparatuses to perform supply of a signal at a respectively different timing, and also to determine that the moving apparatus is stopped at a position of the supply apparatus being an output destination of the order signal, when a wireless signal is received from the moving apparatus within a certain period of time after outputting the order signal.

9. The supply system according to claim 8, wherein

the supply apparatus is an apparatus that supplies electricity to the moving apparatus in a contactless manner, and

the control apparatus outputs a signal to the supply apparatus being an output destination of the order signal to order start of supply or electricity, when a wireless signal is received from the moving apparatus within a certain period of time after outputting the order signal.
