Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio control measuring device, and more specifically, each radio control exercise in a competition using a radio controlled moving body (hereinafter referred to as a radio controlled moving body) such as a radio controlled car competition. The present invention relates to a radio control measuring device capable of accurately measuring various competition information of a body without mounting special equipment on each radio controlled body.

[0002]

2. Description of the Related Art In recent years, a competition of radio-controlled moving bodies, such as a radio-controlled car competition, has been prospering, and many athletes of all ages enjoy the radio-controlled car competition.

In such a radio-controlled car competition,
It is usual to compete for superiority or inferiority of various competition information such as lap time per lap of each radio controlled car, number of laps in endurance race, average hourly speed in endurance race.

In the conventional measurement of competition information of radio-controlled car competitions, for example, a method in which a staff member uses a stopwatch to measure the lap time and a method in which a staff member uses a counter to measure the number of laps are used. Most of the work is done manually, and such a method is very complicated and has many errors, which requires a measurer for each radio controlled car.

In addition, an electric measuring instrument for attaching a transmitter having a frequency unique to each radio controlled car and for receiving an electric wave from the transmitter for analysis and measurement is also used.
In the case of such an electric measuring instrument, there is a problem that it is not very versatile because it is very expensive and it is large in size. In addition, in a radio-controlled car race that competes for speed, if the oscillator is attached to the radio-controlled car, there is a problem that the weight becomes large and the race becomes disadvantageous.
