Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a remote control system and a remote control method for a mobile unit that remotely controls an unmanned mobile unit by radio.

[0002]

2. Description of the Related Art In a conventional remote control system for a mobile unit using wireless communication, an operation command from the operation unit to the mobile unit is performed using a so-called radio transceiver. This radio control transceiver is manufactured exclusively for remote control of a mobile body, and the frequency and intensity of radio waves used there are prescribed by law. In particular, since the maximum value of the intensity of usable radio waves is limited, the distance from the operation unit to the moving object is limited as a result.
For example, the frequency bands permitted to be used for the radio control model are a 27 MHz band and a 40 MHz band, and there are a total of 19 bands. Also, the distance between the operation unit and the moving body is 2-3.
The limit is about Km.

[0003]

A conventional wireless remote control system for a mobile object uses a dedicated radio control transceiver, and the frequency and intensity of radio waves usable there are limited by law. For this reason, since the number of bands is limited, a transmitter / receiver using the same frequency is used nearby, causing a problem that interference occurs. Further, since the intensity of the radio wave cannot be increased, there is a problem that the distance from the operation unit to the moving body is limited. Furthermore, if the mobile unit moves to a position where radio waves transmitted from the transmitter do not reach during operation, there is a problem that the operation of the mobile unit becomes impossible.

[0004] Further, the receiver mounted on the moving body and the transmitter for operation correspond one-to-one, and in order to operate the moving body, a corresponding transmitter is required. There arises a problem that only a person who has it can operate the moving body.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and can greatly reduce the restriction on the distance between the operation unit and the moving body. It is an object of the present invention to provide a remote control system and a remote control method for a moving object.
