Abstract

PURPOSE: To prevent the runaway of a signal due to a train by automatically operating a brake regardless of confirmation handling when signal indication information from a frequency changing type ground substation is a stop indication in a section from the time when a power supply is turned on to the time when pattern control is started. CONSTITUTION: A control device 5 inside a train 2 is provided with a first control part and a second control part. The first control part prepares a checking pattern indicating the allowable train speed on the basis of information from a pattern controlling exclusive ground substation, and when the actual speed of the train 2 exceeds the allowable speed indicated by the checking pattern, a brake 7 is automatically operated to stop the train 2 in a predetermined position. The second control part automatically operates the brake 7 regardless of the presence of the confirmation handling of an operator on the basis of signal indication information from the frequency shift type wayside coil when the second control part receives stop indication information in the section from the time when the power supply of an ATS device is turned on to the time when stop control is started by the first control part.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pattern type ATS device, and more particularly to improvement of train stop control in a section from a departure to a start of pattern control.

[0002]

2. Description of the Related Art At present, as an ATS device which has been put into practical use, a traffic light in front of a train transmits two pieces of indication information, which are R indication and non-R indication, via a ground element by utilizing frequency variation. By sending the alarm to the upper side of the vehicle, an alarm is generated in the case of R indication, and the brake is automatically activated if the driver does not confirm and handle (confirm button operation) within a predetermined time after this alarm is generated. Such a variable-frequency ATS device is generally used. However, such a variable-speed ATS device causes frequent alarms in high-density operation sections where there are many trains operating, because the train interval is short, and the train stop operation after confirmation depends on the driver's attention. Due to such circumstances as described above, in recent years, the pattern type ATS device is used in the high density operation section.

In the train stop control operation by the pattern type ATS device, the distance information to the stop point, which corresponds to the display information of R, Y, and G, is transmitted to the upper side of the car through the ground element, and on the upper side of the car, A check pattern indicating an allowable speed is created based on the received information, and the brake is automatically operated when the train speed exceeds the allowable speed shown by the check pattern. According to this pattern type ATS device, an alarm is not issued unless the permissible speed indicated by the check pattern is exceeded, and when the permissible speed is accidentally exceeded, the brake operates reliably.

By the way, as a conventional pattern type ATS device installed in a line section in which an existing variable frequency ATS device is installed, there is the following one. One is the section where the pattern control of the line section where the ground element for the existing variable-radiation ATS device is installed is required (for example, high-density operation section).
In addition, a method of installing a ground element dedicated to pattern control. Another one
In the same way, the installation position data of the ground equipment (signals, ground conductors, etc.) in the section where the pattern control of the line section in which the existing variable ATS equipment ground conductor is installed is also requested in advance on the onboard equipment side. It is a method of using the existing variable-gyration ground element.

In the former method, when the power is turned on (for example, when the train leaves the station) to the pattern control section,
The train stop control operation is performed by the variable-speed ATS device, and the received information is received from the time when it recognizes that it is the pattern control section by passing through the ground element dedicated to pattern control and receiving the information from the ground element on the vehicle upper side. Pattern control based on
In the latter method, the train stop control operation is performed by the variable-speed ATS device in the same manner as the former between the time the power is turned on (for example, when the train leaves the station) and the pattern control section, and before the pattern control section. Since the point information was received from the ground equipment such as the loop coil installed in the vehicle and it was recognized that it was the pattern control section, the installation position data of the ground equipment stored in advance on the vehicle and the existing location installed in the control section Pattern control is performed based on the information from the variable-range ground element.

[0006]

However, in the conventional pattern type ATS device, it is necessary to receive the point information from the ground coil or the loop coil dedicated to the pattern control and recognize the pattern control section on the upper side of the vehicle. The control operation of the existing variable-frequency ATS device is being performed. That is, as shown in the flow chart of FIG. 6, control is started when the power is turned on at the time of departure of the train, and from the variable radius type ground element (S type ground element) arranged along the track as the train progresses. When the display information is received and it is determined that the stop information is received, an alarm is generated and confirmation is performed within 5 seconds (confirmation button operation)
It is determined whether or not there is. If there is no confirmation treatment (N
O), the brake is automatically applied to stop the train.
If there is (YES), the driver manually operates the brake. After that, when the point information is received from the pattern control-dedicated ground coil or the loop coil, the pattern control start section is recognized and the pattern control is started.

As described above, conventionally, in the section from the power-on to the pattern control section, the operation mode of the brake is different depending on whether or not confirmation is received when the stop information is received from the ground element, so that the driver If the confirmation is wrong,
There is a possibility that the train cannot be stopped before the set stop position. The present invention has been made in view of the above circumstances,
An object of the present invention is to provide a pattern type ATS device having improved train stop control performance in a section from power-on to start of pattern control.

[0008]

Therefore, in the pattern type ATS device of the present invention, based on the information from the ground element,
Create a check pattern on the upper side of the train to show the train speed limit for stopping the train at a predetermined position, and activate the brake automatically when the actual speed of the train exceeds the speed limit shown in the check pattern. The first stop control means for controlling the stop at a predetermined position, and a section from the time when the ATS device is turned on until the stop control by the first stop control means is started. Second stop control means for automatically activating the brake based on the signal indicating information regardless of whether or not the driver confirms the stop indicating information is received.

Further, the first stop control means includes a ground element capable of transmitting information on the distance to the stop point of the train to the upper side of the train,
It is configured to include control means for receiving information from the ground element to create the check pattern, comparing the created check pattern with the actual speed of the train, and controlling the brake. Further, the first stop control means includes a variable frequency grounding element for transmitting signal indicating information to an upper side of the vehicle, a storage means mounted on the vehicle for preliminarily storing installation position information of ground equipment, and a first stop control means. Point information transmission means for transmitting to the upper side of the vehicle that the control section has been reached by the stop control means, and information received from the ground element and stored information in the storage means when control start point information is received from the point information transmission means. And a control means for controlling the brake by comparing the created verification pattern with the actual speed of the train.

[0010]

According to the structure of the present invention, when the signal indication information from the variable frequency grounding element is the stop indication in the section from the time when the power is turned on to the time when the pattern control is started, it is confirmed and treated. Since the brake operates automatically regardless of the situation, it is possible to reliably prevent an accident such as the train moving forward at a traffic light indicating a stop ahead.

Since the pattern control is scheduled to be started during the period from the time when the power is turned on, that is, the time when the train departs to the time when the pattern control is started, the train stop control by the confirmation treatment is performed. Even if it is not done, it will not hinder the train operation. Further, according to the configuration of claim 3, the existing variable-radiation type ground element can be used, and there is no need to newly install a pattern control-specific ground element in the pattern control section. Can be cheaper.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first pattern type ATS device according to the present invention.
The structure by the side of the vehicle equipment of an Example is shown. In FIG. 1, below the tip of a train 2 traveling on a track 1, there is a first car top 3 which receives information from a pattern control-specific ground element (hereinafter referred to as a P-type ground element), and a variable radius type. There is provided a second car upper member 4 for receiving information from a ground member (hereinafter, referred to as S-type ground member). The control device 5 has a built-in microcomputer and the like, and a first control unit that executes pattern type ATS control,
A second control unit that executes the existing variable-frequency ATS control is provided. The first control unit creates a verification pattern based on the distance information from the first vehicle upper member 3 to the stop point, and speed generation that detects the speed from the permissible speed and wheel rotation defined by this verification pattern. The brake 7 is controlled by comparing the train speed information from the machine 6. On the other hand, the second control unit controls the alarm device 8 based on the signal display information from the second vehicle upper shell 4 in the normal variable-radiation ATS control section, and at the time of receiving the stop display information, the confirmation button. The brake 7 is controlled according to the presence or absence of the operation of 9. Further, in the control device 5, a section from when the power is turned on to when the pattern type ATS control is started (a section in which the pattern control is known to be started in advance, and is substantially a pattern control section. 2) has a function of automatically operating the brake 7 regardless of whether confirmation handling is performed when the stop indication is received, prioritizing the control of the second control unit.

On the other hand, in the ground equipment, as shown in FIG. 2, an existing S-shaped ground element 11 (only one is shown in the drawing) is installed along the track 1 in all sections of the line section, and pattern control is performed. A P-type ground element 12 (only one is shown in the figure) is installed in the section. In the figure, 13 is a station and 14 is a traffic light. Next, the operation will be described.

When the train 2 departs from the station 13, the power of the ATS device is turned on. When the power is turned on, the control device 5 starts the ATS control operation as shown in the flowchart of FIG. That is, the train 2 departs from the station 13 and the S-type ground child 11
When passing above, the display information of the traffic signal 14 is received from the ground terminal 11 via the second vehicle upper terminal 4 and input to the control device 5. The control device 5 determines whether or not the received indication information of the traffic signal 14 is a stop indication (R indication) (step 1 (S1 in the figure).
The same shall apply hereinafter))). Then, in the case of the stop indication, the brake 7 is immediately operated without stopping the operation of the confirmation button 9 (confirmation handling) to stop the train (step 2).
If it is not the stop indication, the driver advances the train 2 according to the indication of the traffic light 14. After that, when the train 2 reaches the P-type ground element 12, information for pattern control is transmitted from the P-type ground element 12 and input to the control device 5 via the first car upper element 3. As a result, the determination in step 3 becomes YES and the process proceeds to step 4 to shift to pattern control.

The pattern control is the same as the conventional one, and creates a check pattern indicating an allowable speed according to the position from the current position to the train stop point based on the received information, and the driver controls the train speed according to this check pattern. To do. Speed generator 6
When the actual speed of the train input from exceeds the allowable speed of the check pattern, the brake is automatically activated. Thus, for example, in the section from when the train departs from the station to enter the pattern control section, that is, in the section from when the power of the ATS device is turned on to when the pattern control is started, When the stop indication information is received, the brake is immediately actuated regardless of whether or not it is confirmed and treated, so that an accident in which the train advances the traffic light 14 can be prevented.

Next, a second embodiment will be described with reference to FIGS. 4 and 5. In this, the P-type ground element 12 is not newly installed in the pattern control section, but the pattern control is performed by using the existing S-type ground element 11.

A data input unit 22 is provided in order to previously input the installation position information of ground equipment such as ground equipment and traffic lights in the pattern control section to the control device 5. The installation position information is, for example, an IC
It is stored in a card or the like and input to the control device 5 via the data input unit 22 (in this case, a card reader).

In the operation of this embodiment, the brake 7 automatically operates immediately when the stop indication is received from the S-type ground element 11 in the section from the power-on to the start of the pattern control. This is the same as in the first embodiment described above. And before the pattern control section, the loop coil
When the point information is received from 23, it recognizes that it is the pattern control start section and starts the pattern control. In the pattern control of this embodiment, when the information is received from the S-type ground element 11, the position of the ground element that has passed is recognized based on the installation position information that is input and stored in advance, and the check pattern up to the stop point is obtained. To create. The pattern control for stopping the train thereafter is the same as that described above, and the description thereof is omitted.

According to the second embodiment, since the existing S-type ground element can be used and there is no need to install a new P-type ground element in the pattern control section, the equipment cost in the pattern control section can be reduced. can do.

[0019]

As described above, according to the present invention, the brake automatically operates when the stop indication is received in the section from the power-on of the apparatus to the entry into the pattern control section. In addition, it is possible to prevent the accidental start of the traffic signal due to a misunderstanding of the traffic signal, and further improve the safety.

According to the third aspect of the invention, the existing variable-type ground element can be used, and there is no need to newly install a ground element dedicated to pattern control in the pattern control section.
This has the effect of reducing the cost of equipment.
