Description

Description: TECHNICAL FIELD The present invention relates to a train control device for preventing a train accident due to a signal error or a stop position overrun in train operation of a railroad.

[Conventional technology]

In the method of controlling the train speed by the ground element, as a method of knowing the control condition on the vehicle, a combination method in which the combination of the type of the ground element and the internal state corresponds to the control condition, and the control condition itself is transmitted from the ground element as data. The transponder method is used.

[Problems to be Solved by the Invention]

The above combination method has a simple device and is used in many railways, but many control conditions are up to several types,
The complex train operation zone has the drawback of not being efficient. On the other hand, the transponder method of transmitting control conditions from the ground element to the vehicle has almost no limit on the number of control conditions, but the equipment cost is high, and it is only used in some railways.

The train control device of the present invention aims to dramatically increase the number of control conditions in the combination system.

[Means for Solving the Problems]

According to the present invention, in order to solve the above-mentioned problems, a ground element (P1, Pi, Pn, ...) Which changes the internal state according to the speed limited state of a traffic signal (S) is arranged on the ground in front of the traffic signal. , The control processor (CL), the position detection device (PD) for detecting the absolute position of the train at the time of traveling, and the installation positions of the above-mentioned ground elements (P1, Pi, Pn, ...) are used as identifiers A control data storage device (CD) that stores the controlled conditions, a ground device detection device (SD) that detects the ground device, and a speed control device (SC)
When the train (TR) passes through the above-mentioned ground train (P1, Pi, Pn, ...), the control data corresponding to the train train is specified from the absolute position information of the train at that time. Then, the speed limiting condition is determined from the specified control data, the detected control type of the ground element and the internal state (g, r) of the ground element.

[Action]

When the train detects a ground element, the control data is specified from the train position at that time, and the control condition is determined from the specified control data, the type of the detected ground element, and the internal state. This allows you to set control conditions individually for each ground element,
In the above combination method, it is possible to set the same complicated conditions as when all the ground elements are of different types, and it is possible to realize a control function comparable to the transponder method of transmitting the control conditions from each ground element to the vehicle.

〔Example〕

An embodiment of a train control device according to the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows the configuration of a basic device of the present invention, FIG. 2 shows an example of a control data structure, FIG. 3 shows an example of a position detection device necessary for carrying out the present invention, and FIG. Is according to the invention 1
It is explanatory drawing which shows the example which performs the train control of 2 signal traffic signal area using the ground element of the type 2 internal state. In each figure, the same signals as those in other figures indicate the same components.

First, the configuration of the apparatus of the present invention will be described with reference to FIG. In FIG. 1, TR indicates a train and CL indicates a control processing unit on the train. The control processing device CL is connected to the control data storage device CD, the position detection device PD, the ground child detection device SD, and the speed control device SC. PT represents an allowable speed pattern created in CL. The control data storage device CD stores the position of the signal corresponding to each ground element, the relationship between the control speed at the signal point and the internal state of the ground element in a format that can be indexed from the position of the ground element. S is a traffic light, P1, Pi,
Pn represents a ground element restricted by the traffic light S.

The position detecting device PD detects the running position of the train, and the ground detecting device SD detects that the train has passed over the ground and the internal condition of the ground detecting device. The control processing device CL takes in these pieces of information, searches the control data storage device CD using the train position as a key each time the ground coil is detected, and creates an allowable speed pattern from the information and the ground coil internal state.

Next, FIG. 2 shows an example of control data items in the case of using the ground element in the type 1 and type 2 internal state. In Figure 2, O,
i, K, L, U1, VC1, U2, and VC2 represent data items for one ground element, and values are stored in all data items for all ground elements through which the train passes. O is the position of the ground element, and K is a control type code that distinguishes whether the control point whose speed must be limited to VC is a traffic signal or a switch. L is the distance from the ground element to the control point, U1 and U2 are the ground element internal status codes, VC1 and V
C2 is the speed limit corresponding to each internal status code. The control processing unit CL in FIG. 1 selects the control data item of the passing ground element from the train position, and the distance L to the control point.
And create an allowable speed pattern from the speed limit.

Next, referring to FIG. 3, an example of the position detecting device necessary for implementing the present invention will be shown. In FIG. 3, TG is a wheel rotation speed detector, and PDL is a position calculation processing device. The PDL is connected to the TG and has a position calculation function that calculates the travel distance from the wheel rotation pulse output by the TG and calculates the initial position. Also PD
The L is also connected to the control processing device CL, and has a function of receiving the ground element detection timing via CL and detecting the distance between the ground elements from the ground element detection timing using the position calculation function. The initial position is set by having position setting data in the PDL that associates a combination of multiple inter-ground child distances and the initial position, and searches for position setting data using the detected combination of ground child distances. . The PDL starts outputting position information to CL after the initial position is determined. If the running distance of the train is long and the error of the above position calculation function cannot be ignored, the method of repeating the initial position setting at regular intervals is adopted.

Next, referring to FIG. 4, an example of an apparatus for performing train control of two signal signal sections by using the ground element of one kind and two internal states of the present invention will be shown. In FIG. 4, D means a switch, Pd1, Pd2,
Pd3 represents the ground element controlled by the switch D, and its internal state is g when the switch is in the orientation direction and r when it is in the inverted direction.
Controlled by. Pb1 and Pc1 indicate ground signals respectively corresponding to the two signal traffic lights Sb and Sc, and the internal states thereof are controlled to g when the traffic signal is the progress G signal and r when the signal is the stop R signal.
FIG. 4 (No. 1) shows a state in which the train TR2 is approaching the traffic light Sc and the train TR1 is approaching the traffic light Sb when the switch D is opened in the localization direction and the traffic light Sc is in the G position. Ground child P
c1 and Pd1 are all in the g state, and the allowable speed pattern PT2 of the train TR2 is a straight line that is not subject to speed limitation. The traffic light Sb shows R, and all the ground children Pb1 controlled by it are in the r state. The permissible speed pattern of the train TR1 was created when the ground child Pb1 in the r state was passed, and the traffic signal Sb
The pattern is to stop before. FIG. 4 (No. 2) shows a state in which the train TR2 has traveled to the switch D. The traffic light Sc becomes R and the ground child Pc1 controlled by it becomes r.
This is the state, and the ground element Pd1 controlled by the switch remains in the g state. The signal Sb changes to G and the ground terminal Pb1 changes to g.
It is in a state. The train TR1 detects that the traffic light Sb has turned to G when passing through the ground terminal Pb3 in the g state, and switches the allowable speed pattern PT1 to a straight line that is not in the speed limit.
After that, the vehicle continues to accelerate as shown by the broken line and passes through the traffic light Sb.
In Fig. 4 (part 3), when the traffic light Sc is in the R position and the switch D is in the stationary position, the train TR1 is in the internal state r.
It is in the state of passing through, and the allowable speed pattern PT1 is
The pattern has been rewritten to stop before c. In Fig. 4 (No. 4), the switching machine D then becomes inversion and the ground cub
The train TR1 passes through the ground terminal Pd1 after Pd1 becomes r, and the ground terminal Pc2 is detected after the traffic light Sc becomes G indication. Vp represents the passing speed limit of the switch D in the inverted position. The train TR1 creates and stores an allowable speed pattern for decelerating to the speed limit Vp in front of the switch D when the r state of the ground terminal Pd1 is detected, but the pattern speed of stopping before the traffic signal Sc is lower, so the ground terminal The permissible speed between Pd1 and Pc2 remains unchanged. When the g state of the ground element Pc2 is detected and the pattern of stopping before the traffic light Sc is released, the stored pattern for the speed limit of the switch D is set as a new allowable speed pattern.

〔The invention's effect〕

When performing the above-mentioned control by the conventional technique,
There is a method of categorizing the distance from the ground element to the corresponding traffic light or switch and setting the type of ground element for each distance type. As shown in FIG. 4, when arranging three ground elements in front of a traffic light and a switch, three types of ground elements are required. Further, since the control type is different between the traffic signal and the switch, it is necessary to use a total of six types of ground elements to distinguish them. However, the device of the present invention has an advantage that not only one type of ground element is required but also the position of the ground element can be set quite freely. At present, a simple automatic train stop device using a grounding element of type 1 internal state called ATS-P type is used in many railways. If the present invention is applied to these line sections, it is possible to perform control equivalent to a strict and efficient control method by a multi-type or multi-information ground element at a small cost with only a slight modification of ground equipment, and safety of train operation. It can greatly contribute to the improvement of efficiency and efficiency.
