DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-board device used for an automatic train stopping device (ATS device), an automatic train control device (ATC device) and the like, and a vehicle control device using the same.

[0002]

2. Description of the Related Art Conventional ATS devices, for example, ATS-P
The device is provided with a plurality of P-type grounding elements in one section on the ground side, and transmits information such as the distance from each P-type grounding element to the signal display and the stop position as a control message to the upper side of the vehicle. The on-board device generates a stop pattern based on the received control message, and applies an emergency brake when the vehicle is driven outside the stop pattern. When the content of the control message changes to a higher-level announcement (presentation up), the stop pattern created first is updated to a stop pattern corresponding to the announcement. AT
The SP apparatus is described in detail in pages 40 to 58 of General Electricity, Signal Series No. 7, "ATS / ATC" (published by Japan Railway Electric Technology Association) for railway engineers.

[0003] However, in the conventional apparatus, since the grounding elements are installed at appropriate intervals, when the signal indication in the section changes to the higher-order indication (present-up), the on-board equipment is moved forward. Until the control message is received from the ground child of the above, the change of the announcement cannot be known. For this reason, the stop pattern cannot be updated in response to the present change, which is a bottleneck in increasing the operation efficiency. Also, in order to know the change of the indication immediately, the arrangement interval of the ground children must be narrowed, and many ground children are required.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an on-vehicle device and a vehicle control device capable of updating a stop pattern in response to a change in the present state.

Another object of the present invention is to provide an on-vehicle device and a vehicle control device capable of reducing the number of ground members.

[0006]

In order to solve the above-mentioned problems, an on-vehicle device according to the present invention includes an on-vehicle arm, a power receiver, and a processing circuit. The vehicle upper child receives a control message transmitted from a ground child installed on the ground side. The power receiver receives an orbital current flowing in an orbital circuit installed on the ground side. The processing circuit, when a control message signal output from the vehicle upper arm and a track current signal output from the power receiver are input, and when the content of the control message signal is "red indication", Generating a stop pattern for stopping at a stop position set in, outputting a vehicle control signal according to the stop pattern, and receiving the control message signal of red indication, and then changing the track current signal. When the present up information is detected based on the above, the stop pattern is updated so that the speed at the boundary of the section becomes the allowable speed of the upper present.

[0007] As described above, the vehicle upper child receives the control message transmitted from the ground child installed on the ground side. The processing circuit receives the control telegram signal output from the upper armature,
When the content of the control message signal is “red sign”, a stop pattern for stopping at a stop position set in the section is generated, and a vehicle control signal according to the stop pattern is output. Therefore, when the on-board device receives the control message of the red indication, it can reliably stop the vehicle at the stop position according to the stop pattern.

The power receiver receives an orbital current flowing in an orbital circuit installed on the ground side. When the orbital current signal output from the power receiver is input and the control circuit signal of the red indication is received, the processing circuit detects the present up information based on the change in the orbital current signal, The stop pattern is updated so that the speed at the boundary becomes the permissible speed of the upper present. In the field of vehicle control, generally, when changing the signal presentation, the electrical element of the track current flowing in the track circuit is changed. For example, the frequency is changed, the phase is shifted by 180 degrees, the current flows, or the current is turned off. For this reason, the processing circuit can immediately obtain a change (presentation up information) of the signal presentation to the higher presentation by detecting the change of the electrical element of the orbital current signal,
The stop pattern can be updated in response to the change of the indication. In addition, the processing circuit updates the stop pattern so that the speed at the boundary of the section becomes the permissible speed indicated by the higher rank, so that the operation efficiency can be increased.

The processing circuit generates a stop pattern when the control message signal of the red indication is received, and after receiving the control message signal of the red indication, updates the indication information based on the change in the orbital current signal. When a stop pattern is detected, the first stop pattern is updated to a stop pattern corresponding to the higher-level announcement. For this reason, it is not necessary to provide a ground terminal for transmitting a change in signal presentation in each section, and the number of ground terminals can be reduced.

[0010] A vehicle control device according to the present invention includes an on-board device and a ground device. The on-board device is composed of the above-described on-board device. The terrestrial device includes a plurality of sections and a terrestrial transmitter. Each of the plurality of sections includes at least one ground carrier and a vehicle detection transmitter. One of the ground children is provided at a predetermined distance from the stop position, and transmits a control message to the vehicle child. The vehicle detection transmitter is connected to a front boundary of each section, transmits a track current to the track, and changes an electrical element of the track current according to a change in the indication of the section. The ground transmitter generates a control message and supplies the control message to the ground child. For this reason, all of the features and advantages of the above-described on-board device are obtained, and a vehicle control device that can update the stop pattern in response to the present change and reduce the number of ground members can be obtained.

Other features and advantages of the present invention will be described in more detail with reference to the accompanying drawings.
