Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information transmission device for a railway vehicle for serially transmitting control signals or status monitoring signals,
In particular, the present invention relates to an information transmission device suitable for being applied to an information-oriented railway vehicle that connects and disconnects fixed trains.

[0002]

2. Description of the Related Art In a railway vehicle, particularly an electric vehicle, control devices are distributed and arranged in a plurality of vehicles, and they are operated in a fixed formation by connecting these vehicles. In addition, the number of vehicles in the formation is also adjusted according to the amount of passengers transported, but the increase or decrease in the number of vehicles is often due to connection or disconnection of a fixed formation at a depot or a specific station on the operating route.

FIG. 3 is a view showing a state in which vehicles of an informationized fixed formation, which is the premise of the present invention, are connected. In the figure, 1 to 7 are vehicles, and each of the vehicles 1 to 4 and the vehicles 5 to 7 constitutes one fixed formation. Also, 8, 9
Are transmission lines of each fixed train, 11 to 17 are vehicles 1 to
7 mounted on each of the transmission control devices 10a, 10
b is an operating device, 21a and 21b are auxiliary power supplies, 22a,
Reference numeral 22b is a braking force control device, and 23a and 23b are propulsion force control devices.

A station number is assigned to each of the transmission control devices 11-14 and 15-17 of the vehicles 1 to 4 and the vehicles 5 to 7 which form a fixed train. The station number sends a predetermined signal to the transmission control device. Further, it is used as a code indicating the destination of a signal when it is transmitted to a predetermined control device, and at the same time used as a counting code when displaying the number of connected vehicles on the driver's cab.

For example, a state in which station numbers 1 to 4 are assigned to the transmission control devices 11 to 14 of each of the fixed formations composed of the vehicles 1 to 4 and the fixed formations of the vehicles 5 to 7 are not connected In, the driver sends a command to the control device 23a, so when the operating device 10a is operated, the command is transmitted to the control device 23a of the vehicle 2 as follows.

When a command signal is input to the operating device 10a,
The transmission control device 11 serving as the main station adds the destination station number 2 to the predetermined signal name and transmits the data to the transmission line 8. All the transmission control devices 12 to 14 of each vehicle receive this signal, and if the destination station number matches the own station number, take in the data of the signal name sent subsequently, but the station numbers must match. If so, discard this data. In the above case, the transmission controller 12 receives this data, decodes it, and outputs it to the controller 23a.

FIG. 4 shows a block diagram of the transmission control means 100 in the conventional transmission control devices 11 to 17 mounted on each vehicle, where 8 and 9 are transmission lines, 101 is a signal buffer, and 102.
Is a station number list in which the station number of its own station is registered, 103 is a station number collating means, and 104 is a processing device. When a signal is transmitted through the transmission line 8 as described above, the transmitted signal is once placed in the signal buffer 101 of each of the transmission control devices 11 to 14, and the station number of the own station registered in the station number list 102 is stored. When,
The transmitted station number is collated by the station number collating means 103. Then, if the transmitted station number and the station number of its own station match, the processing continuation signal 110 is issued to the processing means 104 according to the control code in the received data, and if they do not match,
The signal in the signal buffer 101 is discarded.

Upon receiving the processing continuation signal from the station number collating means 103, the processing means 104 processes the text data in accordance with the control code and performs processing such as writing a numerical value to a predetermined variable. Further, when the transmission control device 11 of the main station requests the data of the braking force control device 22a, the signal name and the station number 2 are added to the data request code for the transmission control device 12 which temporarily stores the data. A signal is transmitted to the transmission line 8. The transmission control device 12 recognizes that the request is for the own station because the station number matches the own station number, and transmits the data of the requested signal name by the transmission means (not shown).

As described above, the transmission control device serving as the master station (usually, the transmission control device with station number 1 is assigned to the master station) calls the transmission control device serving as the slave station of each vehicle by designating the station number. It sends and receives information and monitors and controls various control devices for each vehicle. By the way, as described above, the first fixed train composed of the vehicles 1 to 4 in which the station numbers 1 to 4 are allocated to the respective vehicles, and the second stationary train composed of the vehicles 5 to 7

That is, when the second fixed train composed of the vehicles 5 to 7 is driven independently of the first fixed train, the above-mentioned vehicles 5 to 7 of the second fixed train are also usually mentioned above. The station numbers 1 to 3 that are overlapped with the first fixed train are used, and immediately after the two are connected, the station numbers are duplicated and it becomes impossible to exchange signals. Therefore, in the past, all signal transmissions were temporarily stopped at the time of fixed formation connection, the station number was re-registered so that it became the only station number in the formation, and then signal transmission was restarted.

[0011]

As described above, in the conventional art, at the time of fixed formation connection, all signal transmission was temporarily stopped, the station number was re-registered, and then signal transmission was restarted. The condition monitoring signal also stopped, and there was a period when the monitoring function did not work. The present invention has been made in consideration of the above-mentioned problems of the prior art, and also when connecting fixed formations equipped with a serial transmission means of signals for transmitting and receiving control information and status information between respective devices.
