Abstract

PURPOSE:To eliminate the need for a data transmitter by automatically detecting a section between traveling stations and computing the next-station code. CONSTITUTION:An ATC-signal block memory section 21 memorizes the relationship of ATC signals and distances between respective stations, an inter-station distance memory section 22 distances between respective stations and an ATO- signal laying-distance memory section 23 the relationship of ATO signals and distances between respective stations. An inter-traveling station detecting section 24 detects a section between traveling stations on the basis of signals from an ATC signal receiver 7 and an ATO receiver 8 and a speed signal from a tachometer generator 9, and discriminates a next-station code and transmits it over an ATO target-speed generating section 25. The ATO target-speed generating section 25 decides ATO target speed from the next-station code and the ATC signal, and transmits it over an ATO traveling arithmetic section 10. Accordingly, the high-degree automatic operation of a train can be realized without mounting a data transmitter.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to improvements in automatic train operation devices for railway vehicles.

[Conventional technology]

Regarding the conventional system that requires a high-level driving side m using a vehicle 11 and a driving device, a data transmission device is added to exchange operation data between the train and the vehicle.

FIG. 2 shows a configuration diagram of these automatic train operation devices equipped with data transmission devices.

The data transmission base station 1 transmits the operation data (next station code, broadcast message selection code, etc.) necessary for the operation of the 7 trains to the on-board equipment on the 6 cars via the data transmission loop 2. 4 captures the data transmission wave and sends the data to the ATO target speed generator 6 via the data transmission transceiver 5. 6, the next station code that was transmitted data and A
The ATC signal sent from the TC receiver 7 generates an ATO target speed V for automatically traveling between stations.

In the ATO travel calculation unit 10, the ATO target speed ■.

and the train speed Jσ signal generated by the speed generator 9■1. Compare and check and when V r > V v, issue a ka-line command, and then.

When V p < V w, a brake command is output to the power running/brake control device on the vehicle body side to cause automatic running.

In addition, the automatic number/sending device 11 prepares a broadcast sentence using the next station code and the broadcast sentence selection code, and the ATO travel calculation unit 1
Next station information is displayed inside the train by the broadcast activation command sent from 0.
Automatically broadcast information broadcasts such as arrival preview broadcasts.

The AT○ receiver 8 detects a point signal installed on the track, sends the ATO point signal to the ATO travel calculation section 10,
Deceleration control is performed before the ATC signal changes to a lower level, and a fixed position stop pattern is generated from before the station, and station and fixed position stop control is performed to follow the deceleration and stop pattern.

An example of these operating conditions is shown in FIG. 3(a).

The thick solid line shows the ATC limit, the dotted line shows the ATO target speed, and the thin solid line shows the automatic travel curve with AT○.

As shown by the dotted line and the table shown in Figure 3(b), the ATO target speed is not determined simply by the ATC signal, but is determined by the operating route (ATC signal development, gradient, etc.) and inter-station operating speed. The most reasonable target speed is selected and the selection is made based on the next station code transmitted.

[Problem that the invention seeks to solve]

However, such conventional techniques require a data transmission device and are therefore uneconomical.

An object of the present invention is to provide an automatic train operation system that does not require a data transmission device and is highly economical.

[Means for solving problems]

Automatic train operation is carried out under the restrictions of ATC equipment.

This ATC signal is transmitted between each station as shown in Figure 2.
Signal evolution has specificity. (The relationship between distance and signals is different), and the distance traveled between stations is different between each station. Furthermore, each station has its own characteristics in terms of the way that the ground coils are installed for ATO travel.

According to this specific condition, the present invention automatically detects the distance between the running stations, calculates the next station code equivalent to the next station code transmitted by the conventional data transmission device, and uses it as automatic operation control data.

[Effect]

If it is not possible to set the primary station code during the first operation, the automatically detected next station code is saved in a part of the non-volatile memory when the power is turned off, and it is stored at the next power supply time (the next day's By reading it again at the start of work, etc., the next station code can be reliably detected.

In case the next station code cannot be calculated or detected for some reason when traveling between stations, the next station is calculated from the next station code of the section already traveled when stopping at a station.

To set a new next station code and ensure that the next station code can be set.

〔Example〕

Embodiments of the present invention are shown in FIGS. 1 and 4.

FIG. 1 shows the minimum configuration of the present invention, and FIG. 4 shows a configuration in which the effects of the present invention can be exerted even when a part of the device or automatic driving system is defective.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 4.

The ATC signal blockage storage section 21 stores the relationship between the ATC, signal, and distance between each station, and the inter-station distance storage section 22 stores the distance between each station. ATO signal installation distance storage section 23
stores the relationship between ATO signals (point signals) and distances between each station. These stored data are transmitted to the traveling station distance detection section 24. The running station distance detection unit 24 is based on the ATC signal from the ATC signal receiver 7, the ATO signal (point signal) from the ATO receiver 8, and the speed signal (same as the distance signal) generated by the speed generator 9. The distance between the running stations is detected, the next station code is determined, and the code is sent to the ATO target speed generating section 25. As shown in FIG. 2, the ATO target speed generation section 25 determines the most reasonable AT○ target speed between each station from the next station code and ATC signal, and provides it as VF to the ATO travel calculation section IO. The ATO running calculation unit 10 compares Vp with the train speed signal vv from the speed generator 9 and outputs power running and brake commands to the car body side power running and brake control device to automatically control the train.

Normally, the relationship between ATC signals, mileage, and ATO signals between stations is different for each station L:l, but
When the next station code cannot be determined by the running station distance detection unit 24 due to a setting error in the wheel diameter of the train, a difference from the standard deployment due to the approaching distance between ATC4 trains, or a failure of some hardware, In the present invention, a station order storage section 32 is provided, and when the traveling station distance detection section 24 is undefined, the station order storage section stores the next station code one ahead of the next station code when traveling between already translated stations according to the station stop signal;
By automatically setting the next station code sequentially from 32, the next station code is set from the station order storage unit 32 to the running station distance detection unit 24, so that no problem occurs.

Further, the next station code can be set reliably at the start of train operation, and can be set using the next station code from the previous day, as follows. That is, when the device is powered off, the running station distance detection section 2
Part 31 of the non-volatile memory specifies the 9th station code specified in 4.
The next station code is temporarily saved and stored until the next operation, and when the power is turned on at the start of work, the next station code is read out from the non-volatile memory part 31 and reset in the running station distance detection part 24, so that the next station code is always stored. can be specified without exception.

Note that 11 in the figure is an automatic broadcasting device μ].Although this embodiment mainly describes an automatic driving device, it is used as a monitoring device for one train 7, and automatically detects the distance between running stations and collects operation status data. It is also possible to make failure data analysis convenient by making it one of the following.

〔Effect of the invention〕

According to the present invention, without installing a data transmission device,
It is possible to carry out advanced automatic operation of trains, and also to carry out automatic broadcasting, and the cost performance is significantly improved compared to conventional devices.
