It goes without saying that a speedometer device for a railway vehicle is essential for safe operation. Conventionally, this speedometer device has been widely used and is comprised of a speed generator, a generator frequency-voltage conversion circuit, a wheel diameter correction circuit, and a speed indicator. A speed generator is installed on the axle or drive device, and is designed to induce a voltage with a frequency proportional to the speed of the railway vehicle.The frequency of this voltage is converted into voltage by a generator frequency-voltage conversion circuit. The speed indicator is driven, but the wheels wear out as the vehicle is driven, and as the wheel diameter decreases, the frequency relative to the vehicle speed also increases, so the output voltage, which is converted from frequency to voltage, also increases proportionally. Therefore, in order for the speed indicator to indicate accurate speed, when the wheel diameter becomes smaller, it is necessary to reduce the output voltage that converts the frequency into voltage.For this purpose, a wheel diameter correction circuit is used. have.

The voltage is input to the generator frequency-voltage conversion circuit 2, where it is converted into a DC voltage proportional to the wheel rotation speed, and this output is input to the wheel diameter correction circuit 3. Since the wheel diameter changes due to wear during use, the diameter of the wheel on which the speed generator 1 is installed is actually measured at each periodic inspection, and the wheel diameter correction circuit 3 is adjusted using the measured value. The DC voltage proportional to the wheel rotation speed is corrected, and its output is given to the speed indicator 4 to indicate the speed.

is installed on the axle or drive device (not shown), and induces a voltage with a frequency proportional to the speed of the railway vehicle, and the output of the speed generator 1 is input to the generator frequency-voltage conversion circuit 2, where the The frequency of this voltage is converted into a DC voltage proportional to the wheel rotation speed, and the output of this generator frequency-voltage conversion circuit 2 is input to a wheel diameter correction circuit 3. Incidentally, the degree of wear on wheels varies depending on the operation and route of the railway vehicle, but when considering a limited number of routes and operations, there is a certain specific wear pattern. It is possible to replace this with the relationship between traveling distance and wheel diameter, and this is stored in the wear data storage circuit 5 as wear data. On the other hand, the distance meter circuit 7 has a built-in distance meter and transmits the distance traveled to the wear data reading circuit 6. Since the wear data reading circuit 6 obtains information on the distance traveled from the distance meter circuit 7, it requests the wear data at that time, that is, the wheel diameter for that distance traveled, from the wear data storage circuit 5. The expected wheel diameter in relation to the distance is transmitted and becomes the wheel diameter output in relation to the traveling distance of the wear data reading circuit 6, the characteristics of which are as shown in FIG. This wheel diameter output is input to the wheel diameter correction circuit 3, which corrects the DC voltage proportional to the speed already given to the wheel diameter correction circuit 3, and the output of the wheel diameter correction circuit 3 is given to the speed indicator 4. ,
A speed indicator 4 indicates the speed.

The wheel diameter is automatically corrected based on the read wheel diameter data. Therefore, it is possible to save labor in the vehicle inspection and repair system, and the speedometer device is maintenance-free and does not require any adjustment.
