Description of the Related Art As one of on-vehicle devices related to ATC mounted on a Shinkansen, a point detection coil is directed to the ground as an antenna as a vehicle arm, and L (coil component) is partially used as L and C. There is a point detection device provided with an oscillation circuit of (capacitor component), and this oscillation circuit is always 94 KHz.
Is oscillating. On the other hand, a specific point in the orbit is L
A grounding element (coil) having a specific resonance frequency composed of a C circuit is disposed so as to face a point detection coil which is a vehicle element of a train passing therethrough. This earth child,
Broadly speaking, there are W, X, Y, and Z types depending on the difference in information content transmitted to trains passing through this point, and each has a different resonance frequency. Then, by coupling the coil of the grounding element and the point detection coil of the vehicle child facing each other, the LC component of the oscillation circuit of the point detection coil changes, and the oscillation frequency of the oscillation circuit changes (this is referred to as frequency change). It is to let. For example, when a train passes through the point Y installed for the purpose of ATC stop control, the oscillation frequency of the oscillation circuit of the point detection device changes to 124 KHz corresponding to the resonance frequency of the grounding element at the point Y, and the point detection device Is for detecting the changed frequency and outputting information to the ATC.

[0003] Among the ATC tests, there is a point detection test for testing whether the ATC performs a predetermined operation when the vehicle continuously passes the point Y with YY under a certain speed condition. A test coil is set below the point detection coil, which is a vehicle child, to simulate and change the frequency of the ground child, and the test coil is driven to open and close to close the LC circuit.

When testing the ATC on-board equipment of the first car, the point detection tester that changes the frequency of the point detection coil and the ATC operation automatic tester that is connected to the ATC on-board equipment are close to each other, so they must be connected by cable. Is easy, but when testing the ATC on-board equipment of Car 16,
C Even if it is a dedicated inspection warehouse for testing onboard equipment,
A great deal of effort and labor was required to connect a very long cable to a distance of about 400 meters between the point detection coil of the car and the ATC on-board device of the car.

[0005] In an emergency such as a disaster, it is desired that a point detection test can be performed on an actual train track other than a dedicated inspection warehouse. Although it is possible to do so, as long as there is a long cable of 400 meters for connecting the point detection tester and the ATC operation automatic tester, it cannot be made portable.

Accordingly, the present invention provides a method for detecting a point A in a point detection test.
A small and lightweight configuration that eliminates the need to use a long cable to send a test start signal from the TC operation automatic tester to the point detection tester. It is an object of the present invention to provide a point detection test device capable of performing a point detection test even on an actual train track.
