DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a traveling detection device for a moving vehicle suitable for detecting the traveling state of a moving vehicle, such as the position and speed.

Generally, in nuclear power plants, unmanned moving vehicles are used for maintenance and inspection work in radioactively contaminated areas. In other words, equipment for maintenance and inspection work is mounted on a mobile vehicle, and while the position of the mobile vehicle is constantly detected, the vehicle is moved along a predetermined travel route and stopped at an appropriate position to perform maintenance and inspection work. It is something to do.

FIG. 1 is an explanatory diagram showing a conventional moving vehicle and a traveling route. A moving vehicle 3 traveling on a running path 1 is provided with an encoder on its wheels 5, for example, on an axle.
It is designed to transmit a predetermined number of pulses corresponding to 50 rotations of the wheel. Therefore, by counting the number of pulses and knowing the number of rotations of the wheels 5, it is possible to continuously measure the distance traveled by the vehicle.

However, when using an encoder, slip rotation of the wheels 5 is also subject to measurement, so there is a risk that a discrepancy will occur between the actual distance traveled by the vehicle 3 and the value detected by the encoder. Therefore, as shown in FIG. 1, a sensor 7 as a transmitter that emits optical, magnetic, or ultrasonic signals is provided at the center of the lower part of the moving vehicle 3, and a receiving sensor is installed at a predetermined location on the traveling path 1. 9 will be buried. This sensor 9 detects when the mobile vehicle 3 approaches and is located directly below the sensor 7.
It is designed to receive the outgoing signal from sensor 7. Therefore, while the moving vehicle 3 is moving from one sensor 7 to the next sensor 7, if the moving distance detected by the encoder and the actual moving distance recognized by the sensor 9 are different, the detected value by the encoder can be corrected, and accumulation of errors in detected values can be prevented.

However, in this case, even if the accumulation of errors caused by the encoder can be prevented, the distance traveled by the mobile vehicle 3 when it moves between adjacent sensors 7 cannot be accurately detected. Therefore, the position of the moving vehicle 3 cannot be continuously and accurately recognized, and the accuracy of the stopping position of the moving vehicle 3 also decreases.

In this case, the vehicle stores the route as a map in the storage device, and travels along the route while comparing this map with the vehicle's current position.

In this case as well, the current position of the moving vehicle is detected by encoders provided on the wheels of the moving vehicle in the same manner as in the conventional example described above. Therefore, the position of the moving vehicle detected by the encoder may differ from the actual position of the moving vehicle. Therefore, no matter how accurately the vehicle is moving on the map based on the position of the vehicle detected by the encoder, a situation may arise in which the vehicle is not accurately moving along the actual travel route. In this case as well, the position of the moving vehicle cannot be accurately detected, as described above.
