Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-vehicle device and a vehicle control device, and more particularly, to a vehicle control device for a vehicle traveling on a track, such as an automatic train stop device (ATS device) and an automatic train control device ( In the ATC device), when the signal from the traffic signal is given by the variable frequency type, the position of the ground signal from which the signal other than the progress signal is transmitted from the ground signal to the on-board device. Also, the present invention relates to a technique of determining a block boundary of a stop display from the received display signal and outputting a stop pattern signal capable of stopping the vehicle before the block boundary.

[0002]

2. Description of the Related Art A vehicle control device of this type is disclosed in Japanese Patent Laid-Open No. 2-2.
It is disclosed in Japanese Patent No. 37403. In brief, an allowable speed pattern (stop pattern) is set for each closed section, and when the closed section is a stop R indication, the train can be stopped in the closed section. Specifically, a plurality of ground elements, which are the quick-lighting points, are installed for each closed section, and when the ground element arranged at the farthest point from the control point (stop position) is detected, the control logic processing device An allowable speed pattern (stop pattern) is set, and a brake signal is output when the speed at each flash point exceeds the allowable speed. When the allowable speed pattern is canceled on the way, the allowable speed pattern is not set until the closed section in front of the route is entered.

[0003]

However, in the conventional vehicle control device, the train is surely stopped in the closed section from the viewpoint of preventing misrecognition of the traffic signal, so that It has become longer, which is an obstacle to train control with close service intervals.

Therefore, an object of the present invention is to provide an on-vehicle device and a vehicle control device which can set a stop pattern over a plurality of closed sections and can achieve high-density driving.

[0005]

In order to solve the above problems, an on-board device according to the present invention includes an on-board child and a processing section, and the on-board child is a ground child installed on the ground side. For receiving a display signal transmitted from
The position information and the display information are stored, the traveling distance signal and the display signal are input, and the position information designates a blockage boundary and an arrangement interval of the ground elements arranged therebetween, and The indication information specifies the indication method of the adjacent closed section, and when the indication signal is supplied, the ground element that has transmitted the indication signal is determined from the mileage signal and the position information, and the indication is given. From the signal and the indication information, a stop indication blockage section is determined, and the distance from the ground element that has transmitted the indication signal to the blockage boundary of the stop indication blockage section is calculated based on the position information. A stop pattern that can stop before the boundary is set, and a stop signal pattern signal is output.

The vehicle control device includes an on-vehicle device and a ground device. The on-vehicle device is the one described above. The ground device includes a plurality of closed sections and a ground transmitter.
Each of the closed sections has a closed boundary and at least one ground element in the closed section, the ground element transmits a display signal to the car top, and the ground transmitter transmits the ground element. The above-mentioned presenting signal is supplied to.

[0007]

The function of the car top is to receive a signal indicating the ground signal transmitted from the ground guard installed on the ground side. When the display signal is supplied, the ground element that transmitted the display signal is calculated from the travel distance signal and the position information, so the ground element is traced according to the running of the train and the position of the ground element is changed. The running position of the train can be obtained.
In addition, even if an error occurs between the traveling position of the train obtained from the traveling distance signal and the placement position of the ground element obtained from the position information,
Since the running position of the train can be calibrated based on the position information, the running position of the train can be accurately obtained without erroneously determining the ground element.

[0008] The processing section specifies the method of displaying the block sections adjacent to each other by the display information, and determines the block section of the stop display from the display signal and the display information. When the indication information is “the obstruction section is a G, YG, Y, and R four-occurrence section” and the indication signal received from the ground terminal is the YG indication, two points ahead of the obstruction section. It can be determined that the section is the closed section of the stop R indication.

Since the processing unit calculates the distance from the ground element that has transmitted the indication signal to the obstruction boundary of the obstruction section of the obstruction stop based on the position information, the processing unit calculates the braking distance from the stop position to calculate the obstruction boundary. You can set a stop pattern that allows you to stop before. As a result, the stop pattern is not restricted within the closed section, and high-density operation in which the intervals of the closed sections are reduced becomes possible.

Since the processing unit outputs the stop pattern signal, the braking device can control the speed of the train according to the stop pattern signal.

After the stop pattern is set, when the signal indicating the progress G is received from the ground element in front of the route, the set stop pattern is released. After that, when an indication signal other than G indication is obtained, a new blocked R indication block section is obtained,
Set a new stop pattern.

As a result, an on-vehicle device that can set stop patterns over a plurality of closed sections and can achieve high-density operation can be obtained.

Further, in the ground device, each of the closed sections has a closed boundary and at least one ground element in the closed section, and the ground element transmits the indication signal to the car top and the ground transmission. Since the vessel supplies the ground signal to the ground element,
Allows you to set stop patterns across multiple blocked sections,
A vehicle control device that can achieve high-density driving is obtained.

Further, since an appropriate stop pattern is set according to the indication of the traffic signal, even when the train operation interval is shortened and the presentation becomes complicated, an accident due to a misunderstanding of the traffic signal of the driver is caused. Can be prevented.

1 is a block diagram showing the construction of an on-vehicle device according to the present invention. INDUSTRIAL APPLICABILITY The on-vehicle device according to the present invention is used for a vehicle control device of a vehicle traveling on a track, such as an ATS device or an ATC device, in a railway or a new urban transportation system. The on-board device A includes an on-board child 1 and a processing unit 2. In the figure, reference numeral 3 is a train and 4 is a braking device. The on-board device A and the train 3 are exaggerated for convenience of explanation.

The car child 1 is a ground child 1 installed on the ground side.
2, 21, 22, 31, 32, 41, 42, 51, 5
The indication signal S1 transmitted from 2, 61, 62 is received. The indication signal S1 is a signal indication, for example, G (blue),
It is composed of variable frequencies corresponding to YG (blue yellow), Y (yellow), and R (red). Ground element 12, 22, 32, 42, 5
2, 62 are the closing boundaries p of the closing sections 1T to 6T.
1 to p6. Ground element 21, 31, 41,
51 and 61 are provided in the respective closed sections of the closed sections 2T to 6T. Traffic lights 13, 23, 33, 43, 53, 63 are provided at the closed boundaries of the closed sections 1T to 6T. In the embodiment, the method of displaying the traffic light is a four-way display method, and the closed section 6T is set as the stop section. Therefore, the traffic signal 63 indicates the stop R and the traffic signal 53 indicates the Y.
Representation, traffic signal 43 is YG revelation, traffic signals 13, 23, 33
Is the progress G display. Ground element 12, 21, 22, 31,
32 transmits an indication signal S1 indicating the progress G indication. Ground child 4
1 and 42 transmit a YG signal indicating signal S1. The ground elements 51 and 52 transmit the Y-representation signal S1. The ground elements 61, 62 transmit the signal R1 indicating the stop R.

The processing unit 2 includes the position information PI and the presentation information G.
I is stored, and the traveling distance signal S2 and the indicating signal S1 are input. The position information PI includes the obstruction boundaries p1 to p6 and the ground elements 12, 21, 22, 31, 3 arranged therebetween.
Arrangement interval L of 2, 41, 42, 51, 52, 61, 62
12, L21, L22, L31, L32, L41, L4
2, L51, L52, L61, L62 are designated. The presentation information GI specifies the presentation method of the adjacent closed section. For example, the presentation information GI is “the relevant closed section is G, YG, Y,
It is a section of the fourth display of R ”. The position information PI and the display information GI can be given both when the information on all the line sections where the train 3 is operated is given from the beginning or when the information about the line sections operated on the day is given before departure. . Decoding of the signal S1 is performed by checking the frequency of the frequency changing frequency. The travel distance signal S2 is obtained by integrating from the speed signal of the train or the rotation speed of the wheels. In the example,
The rotation speed of the wheel is detected by the tachogenerator TG, and the traveling distance signal S2 is obtained from the wheel diameter and the rotation speed.

When the display signal S1 is supplied, the processing section 2 receives the display signal S from the traveling distance signal S2 and the position information PI.
Determine the ground child who sent 1. As an example, there is a station (not shown) in the closed section 1T, and the train 3 departs from the station,
A case where the processing unit 2 determines the ground element 11 will be described. The train car 1 first receives the signal G1 from the ground train 12 indicating the progressing G.
To receive. The distance L12 from the station to the ground element 11 is stored as the position information PI. When the traveling distance from the station obtained from the traveling distance signal S2 and the distance L12 given by the position information PI match, the ground child who has transmitted the showing signal S1 indicating the progress G is the ground child 11. Figure out. The ground elements 21 to 62 can be similarly indexed.
The traveling distance signal S2 may use either the traveling distance from the station or the traveling distance between the ground elements. When using the distance traveled from the station, it is possible to reduce the influence of changes in vehicle speed due to glide, gliding, etc. of the train 3 by correcting according to the position of the ground element each time it passes the ground element.

The processing unit 2 has a display signal S1 and display information G.
From I, the block segment of the stop indication is calculated. As an example, a case will be described in which the traffic signal is of the four-expression type. When the display signal S1 indicates the progressing G display, there is no speed limit, and it is not necessary to set the stop pattern. In the closed section 4T, when the YG displayed signal S1 is received from the ground element 41, the closed section 6T that is two ahead of the closed section 4T from the display information GI is the stop R displayed closed section. Figure out.
The presentation method does not have to be the same method over the entire line,
The three-view method, the four-view method and the like may be mixed.

Based on the position information PI, the processing unit 2 calculates the distance from the ground element that has transmitted the indication signal S1 to the obstruction boundary of the obstruction section of the stop R indication, and a stop pattern that can stop before the obstruction boundary. TP is set and the stop pattern signal S3 is output. In the illustrated example, the distance to the block boundary p6 of the block section 6T showing the stop R is calculated using the arrangement intervals L42, L51, L52, L61, L62 from the ground elements 41 to 62. Position Lp1 for setting stop pattern TP
Is set by back-calculating the braking distance from the closing boundary p6 of the closing section 6T. Normally, it is set so that it can be stopped 20 meters before the block boundary p6 with a margin.

FIG. 2 is a stop pattern diagram for explaining the operation of the on-vehicle device according to the present invention. The horizontal axis shows the running position of the train, and the vertical axis shows the allowable speed. FIG. 2 will be described together with its operation with reference to FIG.

As described above, the on-board child 1 has the ground child 12
To 62, the processing unit 2 receives the indication signal S1 and the processing unit 2 arranges the position information PI into the obstruction boundaries and the arrangement intervals L12 to L62 of the ground elements 12 to 62 arranged therebetween.
Is specified and the ground elements 12 to 62 that have transmitted the display signal S1 are determined from the travel distance signal S2 and the position information PI when the display signal S1 is supplied, the ground element 12 to 62 depending on the running of the train 3 62 can be traced, and the traveling position of the train 3 can be obtained from the arrangement position of the ground elements 12 to 62. In addition, the traveling position of the train 3 obtained from the traveling distance signal S2,
Even if an error occurs between the position of the ground elements 12 to 62 obtained from the position information PI, the running position of the train 3 can be calibrated by the position information PI, so that the ground elements 12 to 62 are not misaligned and the train is trained. The traveling position of 3 can be accurately obtained.

The processing unit 2 designates the method of displaying the closed sections adjacent to the display information GI, and displays the display signal S1 and the display information G.
Since the block segment of the stop R indication is determined from I, for example,
The detection information GI based on the detected ground element is “the relevant blocked section is the four display sections of G, YG, Y, and R”, and the display signal S1 received from the ground element 41 is the YG display. At this time, it is possible to determine that the block section 6T, which is two blocks ahead of the block section 4T, is the block section indicating the stop R. As a result, the stop pattern TP1 is no longer limited to the closed section, and high-density operation in which the intervals of the closed sections are reduced becomes possible.

Since the processing unit 2 calculates the distance from the ground element 41 which has transmitted the YG showing signal S1 to the closing boundary p6 of the closing R showing closed section 6T based on the position information PI, the stopping position By calculating the braking distance back from, it is possible to set the stop pattern TP1 that can stop before the closing boundary p6.

After setting the stop pattern TP1, the processing section 2
When the ground signal in front of the route, for example, the ground signal 42 gives a display signal S1 indicating the progress G, the stop pattern TP
Cancel 1. Signal S1 of the YG signal from the ground element 51
Is given, a new stop R present closed block section is obtained and a new stop pattern TP2 is set. In the illustrated example, the new stop R indication block section is 7T, and the new stop pattern TP2 is set so that the train 3 can stop before the block boundary p7.

When the number of ground elements provided in the closed section is increased, cancellation of the stop pattern due to the progress G indication becomes faster,
Train speed can be increased.

Since the processing unit 2 outputs the stop pattern signal S3, the braking device 4 can control the speed of the train 3 by performing speed check along the stop pattern signal S3.

As a result, the on-vehicle device capable of setting the stop pattern TP over a plurality of closed sections and achieving high-density driving can be obtained.
