Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

2. Description of the Related Art Conventionally, as a technique for measuring the traveling time of a moving body, there have been methods using a manual stopwatch, an infrared measuring system, or a small tag. When measuring time with a stopwatch, a measurer was placed at the measurement point and the stopwatch was visually pressed. When measuring with an infrared measurement system, an infrared projector,
Light receivers were installed at both ends of the measurement line at the measurement point, and the time was measured by a signal that entered when the moving object blocked the infrared rays. When a small tag is used, a small tag is attached to the moving object, and the time when the tag reacts to radio waves from an antenna installed near the measurement point is set as the measurement time.

In order to obtain information on the speed of a moving object, a dedicated measuring person uses a stopwatch to calculate the speed of the moving object from the time difference between two measurement points.

[0004]

However, the above-mentioned conventional stopwatch has a drawback that accuracy is deteriorated because it is measured visually. Further, when there are a plurality of moving bodies, it is difficult to measure the plurality of moving bodies by one measuring person, so that there is a problem that a large number of humans are required.

In the conventional measuring system using infrared light, there is no problem when one moving object passes through the measuring point. However, when a plurality of moving objects overlap each other and block the infrared light, each of the moving objects overlaps. Identification was not possible. Also,
There was a problem that the work of installing the infrared light projector and the light receiver was troublesome.

[0006] Further, in the conventional time measurement using a small tag, the timing at which the tag enters an area where radio waves reach, centered on the antenna, is not necessarily on the measurement line, and a measurement error is generated. Had a point.

Also, when measuring the speed of the above-mentioned conventional moving body, a dedicated measuring person is required, and when the number of moving bodies is increased, the trouble and labor required for the moving body are required. Had.
