BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an Automatic Train Stopper (ATS) device. In particular, when the connection line between the ground and the ground self-control relay is short-circuited, a non-active state of the ATS device is generated because it generates a predetermined frequency indicating a short-circuit state. The grounder is in an unbalanced state because it detects the ATS terrestrial which prevents the non-active state and the predetermined frequency that occurs when the magnetic field is shorted and performs a predetermined process. The present invention relates to an ATS in-vehicle device that can detect a non-active state that can inform a driver.

In general, the ATS apparatus includes a grounder (11) composed of a capacitor (C) and a coil (L) as shown in FIG. 1 and FIG. Relays RL _1, RL _{2 ,} RL _n-1, RL _n and capacitors C _1, C _{2 ,,} C _n- which are turned on / off by a predetermined control signal. _1, C _n ), and the capacitor C of the terrestrial 11 is connected in parallel, so that the capacitance of the terrestrial 11 is varied according to a predetermined control signal, thereby reducing the resonance frequency. A ground control relay 12 for changing; The signal generator 13 is selectively connected to the ground control relay 12 to generate a predetermined relay control signal as a speed command signal, thereby controlling the relay of the ground control relay 12 and controlling a traffic light and the like. Ground device unit 10 consisting of; A primary box 21 in which the primary coil and the primary coil are inductively coupled with a predetermined coupling degree to sense the resonance frequency of the ground wave 11 by frequency induction; It consists of an amplification circuit section and an oscillation circuit section, and performs oscillation at a predetermined frequency (for example, 78 KHz) to feed back through the coil of the car box 21 and at the same time the frequency that has been reacted to the coil of the car box 21. An oscillator 22 for oscillating and amplifying; A frequency detector (24) for detecting and outputting a frequency output from the oscillator (22) because it is composed of a plurality of band pass filters (BAND PASS FILTER) and the like and connected to the oscillator (22); A speed detector 23 attached to the wheel side of the train for detecting the speed of the train; When the signal input from the frequency detector 24 and the speed detector 23 is compared and judged by a predetermined method, a predetermined alarm control when the actual speed of the train exceeds the speed commanded by the ground apparatus unit 10. A logic judgment control device 26 for generating a signal; Connected to the logic determination control device 26, when an alarm control signal is generated in the logic determination control device 26, an alarm sound and a display control signal are generated for a predetermined time, and then the actual train An alarm device 27 for generating a predetermined braking signal when the speed does not become smaller than the commanded speed; An emergency brake 28 connected to the alarm device 27 for braking the train when a braking signal is generated from the alarm device; Connected between the alarm device 27 and the logic judgment control device 26, when a display control signal is generated in the alarm device 27, a visual alarm is displayed, and a recovery command can be commanded by the driver. In this case, it is composed of an on-vehicle device section 20 composed of a display control device 25 which transmits the signal to the logic determination control device 26 and simultaneously displays a predetermined signal generated by the logic determination control device 26. The actual speed of the train was controlled by the command speed calculated from the track occupancy state of the other train.

In other words, by calculating the track occupancy state of the preceding train, that is, the distance between the preceding train and the following train, the traveling speed of the following train is calculated, and the resonance frequency of the grounder 11 is changed and transmitted to the vehicle box. By controlling the speed of the train.

For example, if the speed of the train is divided into five and the speed is to be controlled, five capacitors are connected to the ground person 11 and the ground control relay 12 through a relay, and the signal 13 By selectively connecting), five resonant frequencies were created to control the speed of the train at the speed corresponding to each frequency (see Figure 2).

In other words, the lead wire 12a connecting the coil L of the ground person 11 and the ground magnetic control relay 12 may be short-circuited due to repair of the track, new installation work, or other causes. In this case, the LC resonant circuit completely loses its function and cannot cope with the car box 21 of the on-vehicle unit 20 (this is called the groundless non-movement state). Train overspeed automatic control function will be disabled. This is a situation that frequently occurs in reality, which causes a decrease in the reliability of the ATS device.
