PROBLEM TO BE SOLVED: To provide a ground spot transmission device by wireless power supply in which mobile control and maintenance of the device can be performed at the same frequency, and which can be operated with lower power since there is no need to supply power to an unnecessary function at the time of mobile control in the device required to be operated with low power at the time of mobile control.SOLUTION: A ground spot transmission device by wireless power supply has a system configuration for receiving a power wave by a wireless reception part, generating operation voltage in a circuit by a constant voltage generation part after converting the power wave from an alternating current to a direct current by a rectification part, and transmitting information in a storage part to an on-vehicle device by supplying power to a telegram output part, and is characterized by including a function to rewrite the information in the storage part in the device with a modulation signal by radio having the same frequency as the power wave. |
