Description

  The present invention relates to a train control apparatus that mainly generates a speed check pattern on a vehicle and performs train speed control using the generated speed check pattern.

  In recent years, in order to reduce train operation intervals and improve ride comfort, on the basis of predetermined digital information (ATC information) obtained from the ground, a speed check pattern is mainly generated on the vehicle (train), There has been proposed a one-stage control digital ATC system train control apparatus that performs train speed control using the generated speed check pattern (see Non-Patent Document 1). The train control apparatus according to the one-step control digital ATC system always uses predetermined data (information) obtained from the ground side and predetermined data (information) such as track circuit permutation data stored in advance in the on-board apparatus. Thus, a single parabolic speed check pattern from the current position to the stop target point can be generated.

The on-board device of the above-described one-stage control digital ATC system train control device is based on the data from the ground unit installed at a predetermined interval on the rail on which the train travels, and the ground side is mainly used as the ground unit installation interval. Because it is a technique similar to the ATS-P type multistage control system that generates a step-like speed check pattern corresponding to the above, a signal (information) from the ground side similar to the well-known ATS-P type on-board device is used. It consists of various processing units such as a receiving unit for receiving and a speed / position detecting unit for detecting the speed and position of the own train.

By the way, the train control device of the one-step control digital ATC method that mainly generates the speed check pattern mainly on the vehicle upper side according to the above proposal, the signal information and the distance / position necessary for the speed check pattern generation obtained from the ground side always. A predetermined speed check pattern based on predetermined data such as information (hereinafter referred to as ground data ) and basic data such as track circuit permutation data (hereinafter simply referred to as basic data) stored in advance on the vehicle . However, when the contents of basic data stored in advance in the on-board device are changed due to a change in the route on the ground side, it is natural that new basic data must be stored. is doing. For example, when the track circuit permutation data is changed due to the increase or decrease of the track circuit, or when the track circuit permutation data is changed due to the addition of a new station, it is stored in advance in each processing unit constituting the on-board device ( It becomes necessary to change the basic data to be set. For this reason, a train control device that can efficiently cope with such a data change has been desired.

  In addition, in a one-stage control digital ATC system train control device that mainly generates the speed check pattern mainly on the upper side of the vehicle, various data used in each processing unit of the on-board device can be transmitted and received safely and efficiently. It was hoped that.

  Therefore, the present invention has been made in order to meet the above-mentioned demand, and its purpose is to provide an on-board device when basic data needs to be updated due to a change in the route on the ground side or addition of a new station. An object of the present invention is to provide a train control device that can easily change basic data stored in advance and can distribute the changed basic data to each processing unit safely and efficiently.

In order to achieve the above object, the present invention generates a predetermined speed check pattern in the on-board device based on the ground data obtained from the ground side and the basic data stored in the on-board device in advance. In the train control device that performs train control using the speed check pattern thus formed, (a) a receiving unit that configures the on-board device, a security control unit that generates the predetermined speed check pattern, a train brake, and the like. A monitoring unit for monitoring a processing unit including a driving control unit for driving control via a communication area network formed between them, and (b) changing the basic data stored in the on-board device in advance or adding a new station An external device such as a personal computer that downloads new basic data to the monitoring unit every time it should be updated, etc., and (c) downloads the external data from the external device to the monitoring unit It is a data transmission means for downloading by time division the stored new base data to the said processing unit from the monitoring unit, (d) the monitoring unit, the processing when the power supply of the vehicle on the device is OFF The basic data stored in the unit is cleared, and when the on-board device is turned on, the data sending means is made to download the basic data from the monitoring unit to the processing unit again. It is a feature.
Delivery from the monitoring unit to the processing unit is preferably performed through the LAN of the optical cable.

According to the present invention, whenever basic data is to be updated due to a route change, new station addition, etc., new basic data is downloaded from a personal computer to the monitoring unit by communication and quickly stored in the on-board device in advance. The basic data being updated can be updated. In addition, since data transmission means for downloading in time division from the monitoring unit to each processing unit is provided, new basic data can be quickly distributed to each processing unit. Therefore, the speed check pattern can be effectively generated on the vehicle. Further, when the power of the on-board device is turned off, the basic data stored in the processing unit is cleared, and when the power of the on-board device is turned on, the basic data is sent from the monitoring unit to the data sending means. Therefore, basic data including always updated track circuit permutation data and the like is used. Therefore, it is not necessary for the on-board device to have spare parts such as a spare storage device corresponding to the update of the basic data.
When the distribution from the monitoring unit to the processing unit is performed via a LAN formed of an optical cable, it is excellent in noise resistance. Therefore, new basic data can be distributed to each processing unit safely and efficiently.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a train control device according to an embodiment.

A train (vehicle) A traveling on the rail R is equipped with an onboard device B for realizing the train control device of the present invention. This onboard device B is composed mainly of a CPU, and is connected to the rail R via a monitoring unit 1 that monitors the entire onboard device B and an onboard (antenna) a provided at the lower front of the train A. Receiving unit 2 formed by including an amplifying circuit and a filter circuit for receiving predetermined ATC information obtained or predetermined position information from a ground unit (not shown), that is, a predetermined signal from the ground side, and a CPU is organized around a secured control unit 3 for generating a predetermined speed Shosa pattern based on the basic data being ground data and prestored obtained from the ground side, the operation control unit 4 configured around a CPU, The common part 5 is comprised.

  The operation control unit 4 includes an operation control signal generation unit 4a and a speed / position detection unit 4b. The operation control signal generation unit 4a generates a control signal for the train system (not shown) so that the train operation is performed in accordance with the generated speed check pattern, and the speed / position detection unit 4b Based on a speed generator (not shown) provided on the axle and position information from the ground side, the own train position and the own train speed can be detected. Furthermore, the common unit 5 is formed by a relay logic unit, and is configured to input a signal from the operation control signal generation unit 4a and to drive and control devices (not shown) such as a train brake. .

The monitoring unit 1, the receiving unit 2, the security control unit 3 and the operation control unit 4 have a multiplexed configuration (duplexed in the illustrated example) and are connected via communication lines L1 and L2 made of optical cables. Thus, one communication area network (LAN) is configured . Therefore, although not shown, each part (1, 2, 3, 4) includes a known optical / electrical converter and an electrical / optical converter. As described above, since the LAN composed of the optical cable is configured , the noise resistance is excellent, and the safety is ensured by multiplexing.

  In FIG. 1, reference numeral 10 denotes a portable personal computer that is an example of an external device. The personal computer 10 is configured to be detachably attached to the monitoring unit 1 via the cable C. Therefore, the monitoring unit 1 has a built-in communication control unit for communicating with the personal computer 10.

  The control operation will be described below using the flowchart of FIG. Now, it is assumed that an onboard device B is newly installed on the train A. Then, it is assumed that the personal computer 10 is connected to the monitoring unit 1 via the cable C (Yes in Step 100. Hereinafter, the step is referred to as “S”). In a storage unit (not shown) such as a flexible disk (FD) of the personal computer 10, basic data that must be stored in advance by the on-board device B that has been carefully checked in advance is stored. That is, data (loading data) to be downloaded from the monitoring unit 1 to each of the units 2, 3, and 4 is stored in the storage unit of the personal computer 10. The loading data includes predetermined version data (version n (n represents a generation)) indicating the generation of data contents.

  The content of the loading data is basic data for mainly generating a speed check pattern on the vehicle (train A), and includes loading data header data (loading data version n, program data version n of each part, Size of each data ...), track circuit permutation data, track circuit attribute data, jump data, section jump data, speed limit data, branch data, curve speed limit data, line segment maximum speed data, gradient data, tunnel data, deceleration performance Data, running resistance data, various constant data, etc. are included.

  When downloading of basic data from the personal computer 10 to the monitoring unit 1 is completed (Yes in S102 and S104), the personal computer 10 is removed from the monitoring unit 1, and then the basic data is loaded from the monitoring unit 1 to each of the units 2, 3, and 4 ( Downloaded) and stored in each of the units 2, 3 and 4 (Yes in S106 and S108). The loading from the personal computer 10 to the monitoring unit 1 is performed every time the basic data is updated due to a route change, a new station addition, or the like, and the version n is updated every time the update is performed. Basic data is stored.

When basic data is stored in each of the units 2, 3, and 4 from the monitoring unit 1, train operation using the basic data becomes possible (S110). In other words, the on-board device B always uses the ground data obtained from the ground side and the basic data (loading data) such as the track circuit permutation data stored in advance on the on-vehicle device B to stop from the current position. A single parabolic speed check pattern up to a point is generated, and train i is operated using the generated speed check pattern. Then, when train A reaches a ground element (not shown) during this operation, the position information is obtained from the ground element and the position of the own train is corrected.

  When the operation of train A is completed and the power of the onboard apparatus B is turned off, the loading data stored in each of the parts 2, 3, and 4 is cleared. Then, when the operation of the train A is started and the power of the on-board device B is turned on (Yes at S112), the basic data is downloaded again from the monitoring unit 1 to the respective units 2, 3, and 4 (S106).

  Although omitted in the flowchart of FIG. 2, transmission of basic data from the monitoring unit 1 to the units 2, 3, and 4 is always distributed in a time-sharing manner. Therefore, even if the power is turned ON / OFF for each unit 2, 3 and 4 alone, the unit can be easily started up. Also, the version data (version n) held by the monitoring unit 1 and the version n stored in each unit 2, 3, 4 are always checked. If they do not match, reloading is performed in each unit 2, 3, 4 Is done. In addition, the basic data is transmitted at a faster period than the normal time for a certain period of time when the on-board device b is started up, and the basic data is stored in each of the units 2, 3, and 4 quickly Thus, the start-up time of the on-board device B is shortened. Further, the basic data includes information different for each vehicle, and the performance of each unit is associated with the basic data based on the basic data. Therefore, the basic data can be used for each vehicle only by changing the basic data. For this reason, it is not necessary to have spare parts for each part for each vehicle.

It is a schematic structure figure of a train control device concerning one embodiment of the present invention. It is a flowchart which shows control operation.
