DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable-speed on-vehicle pattern train control apparatus, and more particularly to an ATS-S type automatic train stop system.

[0004] The ground element a is composed of a series resonance circuit of a coil L and a capacitor C, and can transmit a signal of a variable frequency (fx) consisting of a predetermined frequency toward a vehicle (train A). Is configured.

[0005] The train A is equipped with an ATS receiver 1 capable of generating a speed check pattern P on a car. When the ATS receiver 1 receives a signal of the variable frequency (fx) from the ground child a via the vehicle child (vehicle antenna) b, the frequency within the ATS receiver 1 is received. fx) and receives a signal from the ground terminal.

[0006] The ATS receiver 1 is configured to be able to notify a crew member by a bell or the like when receiving a signal of the variable frequency (fx). The ATS receiver 1 is configured so that a signal can be input from a speed generator G attached to the axle of the train A to measure the traveling distance. Therefore, when the train A travels a predetermined distance D with the speed reduced so as to be lower than the speed check pattern P, the train is operated so that the train speed becomes equal to or lower than a predetermined speed limit (Vpx). If the train speed is the speed check pattern P
Is exceeded, a brake signal is sent from the ATS receiver 1, and the brake is automatically activated.

The table shown in FIG. 4B shows the speed limit (V
(px) indicates the frequency-change frequency (fx) assigned to each.

FIG. 5 shows a case where a traffic signal S is installed at a position corresponding to the start point of the speed limit (Vpx) in FIG. Is shown.

That is, the traffic signal S is stopped (hereinafter, referred to as a stop signal).
It is called "R announcement". ), The contact H of the signal relay
R has been restored (OFF), and power is not supplied to the ground slave relay QR.
Are in a recovery (OFF) state. Therefore, a resonance circuit is formed by the capacitor C1 and the coil L connected in series with the capacitor C1.

When the ATS receiver 1 receives the variable frequency (f4), it is notified that the traffic signal S ahead is the R display. When the crew does not perform a predetermined driving operation in response to this notification, a brake signal is output from the ATS receiver 1 to ensure safety.

When the traffic light S changes from the R display to the upper warning display (hereinafter referred to as "Y display") or the progress display (hereinafter referred to as "G display"), the contact of the signal relay is issued. H
Since R is turned on, the contact of the ground relay QR also operates (O
N) Then, the ground element a 'becomes an oscillating circuit composed of the coil L and a pair of capacitors C1 and C2 connected in parallel. Therefore, from the ground child a ', the frequency-change frequency (f0) which means a release different from the frequency-change frequency (f4) up to that time is transmitted.

As described above, the ATS
The -S type system has the feature that the safe operation of the train can be ensured based on the information from the ground plane. However, since the amount of information from the ground is small, there is a problem that the train control cannot be performed in detail.

That is, the ATS-S type system has only two types of information amounts, "1" and "0". Therefore, in the ATS-S system applied to FIG. Can be notified that there is a speed limit section, but it is not known how long the speed limit section is, what type of speed limit it is, and the number of speed limits cannot be large. Was. Further, in the ATS-S system shown in FIG. 5, it was not possible to know information such as the speed limit of the branching device at the traffic light only by presenting the traffic light.
