Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a train monitoring device for a train formation in which a plurality of vehicles are connected in an arbitrary manner. This system is connected to a train monitoring system that is automatically carried out by a monitoring station.

[Prior Art] Figure 2 is a block diagram showing a conventional train monitoring device described in, for example, the ``Domestic Symposium on Cybernetic Disease Utilization in Railways'' (19th, p. 496). ) to (104) are monitoring stations installed in each vehicle of a four-car train, and monitoring stations (111) to (114) are installed in each vehicle along with each monitoring station (101) to (104), and monitor the operation of the vehicle to which it belongs. Vehicle equipment for supplying information, (
121) and (124) are installed on the cars at both ends, which serve as the driver's cabs, and are used to monitor the entire train. (L) is used to route the monitoring stations (101) to (104) and transmit information. This is a series transmission line.

A conventional train monitoring device is configured as described above, and has four monitoring stations (101) to 1, corresponding to cars No. 1 to No. 4, respectively.
Among (104), the monitoring station (101) or (104) of car No. 1 or No. 4, which is the lead vehicle, operates as a control station for serial transmission, and the other monitoring stations (102) and (103) act as dependent stations. It's supposed to work.

Now, assuming that the left direction in the drawing is the traveling direction, the monitoring station (101) of car 1, which is the control station, is the monitoring station (102) of the subordinate station.
) to (104) are sequentially called out via the serial transmission line (L), information on each vehicle is collected, edited for display, and then displayed on the displays (121) and (124).

The monitoring stations (102) to (104) that are subordinate stations have switches (not shown) for setting the car number of the vehicle to which they belong, and this allows the station number of the own station to be set to 2 to 2, which is the same as the car number.
It has been decided to be 4.

Therefore, only when the monitoring station (toi) of the control station specifies its own station number and requests a response via the transmission line (L), each monitoring station (102) to (104) of the subordinate station transmits information about the vehicle to which it belongs to the monitoring station (101) as a response.

At this time, if the train is a fixed formation of four cars, it is determined that the cars are connected in the order of car number. Therefore, for example, the monitoring station for car No. 1 (
101), each monitoring station (1oz) to (10oz) including itself.
It is possible to determine the position of a vehicle equipped with 4) in the train composition (i.e., the number of vehicles from the beginning).

[Problems to be Solved by the Invention] As described above, the conventional train monitoring device operates in a semi-fixed manner to each monitoring station (101) to
Since the station number (104) is determined, if train configurations are combined or changed on a commercial route, multiple monitoring stations with the same station number will be created, and the monitoring station data will be There were problems in that it became difficult to send and receive data, and it was impossible to determine the position of the vehicle on which each monitoring station was installed in the train composition.

This invention was made in order to solve the above-mentioned problems, and it is possible to distinguish the station numbers of each monitoring station even for train formations configured by connecting or separating arbitrary vehicle formations, and The purpose of the present invention is to obtain a train monitoring device that can determine the position of a vehicle equipped with a monitoring station on a train composition.

[Means for Solving the Problems] The train monitoring device according to the present invention includes a power line for supplying power through each monitoring station, and a power line provided at each monitoring station,
It is equipped with an opening/closing circuit for sequentially connecting power lines to adjacent monitoring stations, and a starting switch for initially supplying power to one of the monitoring stations in response to a cab starting signal.

[Function] In this invention, the monitoring station to which the IC source is first supplied becomes the control station, and the switching circuits are sequentially closed to sequentially start up adjacent monitoring stations via the power line.
The position and operation information of the vehicle to which each monitoring station belongs is input to the monitoring station serving as a control station via a serial transmission line.

Together with the SM 24), it constitutes an opening/closing circuit within each of the monitoring stations (11) to (14), and is controlled to open and close by each of the monitoring stations (11) to (14).

(Sl+131) and (S1434) are respectively provided between the monitoring stations (11) and (14) in the vehicle at both ends having the driver's cab and the vehicle DC1i source (E), and are closed by the driver's cab activation signal. The other end of each start switch (S1+131) and (34) is connected to the connection point of the open/close switch (SWII) and (21) and the connection point of the open/close switch (14) and (24). power supply circuit (
41) and (44).

Next, the operation of the embodiment of the present invention shown in FIG. 1 will be explained. Initially, each activation switch (
SW31) and (SW34), each open/close switch (SWl
It is assumed that l) to (SnI2) and (SW21) to (SW24) are all off, that is, open. Furthermore, as described above, it is assumed that the train is operated with the left side of the drawing as the traveling direction.

(1) First, when the driver's cab (not shown) on the vehicle (1) is activated, this driver's cab activation signal causes the activation switch (S
1131) is turned on. Therefore, the vehicle DC power (E) is supplied to the power supply circuit (41) in the monitoring station (11), and the monitoring station (11) is activated. At this time, since the diodes (Dll) and (021) connected in parallel to each open/close switch (Sl+111) and (Sll121) are in opposite directions, each power line (Pl) and ( Vehicle DC power (E) is not supplied to Pl).

(It) The activated monitoring station (11) has operational information <1a
), or by detecting that station number command (calling) information from another station is not input via the serial transmission line (L) even after a predetermined period of time has elapsed, the driver's cab of the own station Determine whether it has been activated. Then, it decides its own station number as "1", and opens/closes the switch (SWII> and (
SW21) is turned on and the station starts operating as a transmission control station. In other words, the monitoring station (11) that has become the control station is
A command to set the station number of the monitoring station (12) in the adjacent vehicle to "2" is repeatedly transmitted on the serial transmission line (L).

(Ill) When the open/close switch (SN21) is turned on, the vehicle DC power (E) is supplied to the power line (P2), and this voltage is applied to the rear adjacent monitoring station ( 12) is applied to the power supply circuit (42). Therefore, the monitoring station (12) starts operating, and the station number "2" is repeatedly transmitted on the serial transmission line (L).
and determines its own station number as "2". At the same time, a response signal indicating that the station number command has been received is transmitted to the monitoring station (11) via the serial transmission line (L).

(IV) The monitoring station (11) that received the response signal from the monitoring station (12) informs the monitoring station (12) that the station number is "2".
It notifies that it has been registered as a dependent station of , and also sends a command to turn on the open/close switches (SN12) and (SN22).

(V) Upon receiving this command, the monitoring station (12) turns on the on/off switches (SN12) and (22), and supplies the vehicle DC power (E>) to the power line (P3). ) is applied via the diode (013) to the power supply circuit (43) in the monitoring station (13) adjacent to the rear, and the monitoring station (13) is activated.

(■) Next, the monitoring station (11) as a control station further sends a command to the monitoring station in the adjacent vehicle to set the station number to "3".
Repeatedly transmit on serial transmission line (L). This command is then received by the monitoring station (13) immediately after being activated.

Note that this command is also sent to the monitoring station (12), but since the station number has already been determined as "2", it does not respond to it.

(■) Upon receiving the station number command from the monitoring station (11), the monitoring station (13) determines its own station number as "3" and sends a response signal indicating acceptance of this command to the monitoring station (11). 11) to let you know.

(■) Hereinafter, as in the case of monitoring station (12) (paragraph v), monitoring station (13) is registered as a subordinate station of station number "3", and further opens and closes according to commands from monitoring station (11). Switches (S11113) and (S1123) are turned on to supply DC power (F, ) to the power line (P4).

([) Then, the procedure in which the monitoring station (11) transmits a command to set the station number [4] and the monitoring station (14) that receives this is registered as the station number "4" is the same as described above.

(X) Finally, the monitoring station (11) turns on the on/off switches (SN14) and (SN24) in the monitoring station (14),
A command to set the station number to "5" is sent on the serial transmission line (L), but in this example, there are only up to 4 monitoring stations due to the 4-car train, so the command to set the station number to "5" is sent. The monitoring station (11) continues to send this command, but if no response is received after a certain period of time, there is no vehicle after vehicle (4). It is judged that the command is terminated.

As described above, by sequentially closing each on/off switch (SN21) to (SN23) according to the procedures in paragraphs (1) to (X), the monitoring stations (11) to (14) are connected to the power line 1Jlj and the line ( P2) to (P4), and by transmitting a station number command, i.e. calling, the driver's cab is sequentially routed from the activated leading vehicle (1) to rl'', r2J,'
Station numbers r3J and '4J are assigned. Thereafter, these station numbers can be used to identify each other's vehicles, to know the current train configuration, and to accurately exchange data such as operating information of each vehicle (1) to (4).

Therefore, the monitoring station (11) periodically monitors each monitoring station (12).
~ (14) and each monitoring station (12)

) can be displayed.

Furthermore, when there is a change in the train composition, the on/off switches (SWll) ~ (SN14) and (SN21) ~ (
S 24), start switch (Sli131) and (SN
34) and repeating the procedures in items H) to (X). In this way, the position of each vehicle in the train formation can always be accurately initialized.

In the above embodiment, the left side of the drawing was taken as the traveling direction, but even if the right side of the drawing was taken as the traveling direction of the train, the starting switch (S1134) in the vehicle (4) is turned on by the cab starting signal, and the power supply circuit (44) is turned on. Start up and connect the power lines (P4) to (
P2) is energized, and the diodes (023) to (
021), the respective power supply circuits (43) to (41) are activated, and the station numbers are similarly determined as "1" to "4" in order starting from the vehicle (4).

In addition, although we have shown the case where the monitoring station in the first car of a train formation operates as a control station, as long as the condition that it is one of the cars at both ends of the train formation is met, the monitoring station that operates as a control station can act as a train control station. It may be installed either at the beginning or at the end.

[Effects of the Invention] As described above, according to the present invention, a power line for supplying power through each monitoring station, a power line provided at each monitoring station,
It is equipped with an opening/closing circuit for sequentially connecting power lines to adjacent monitoring stations, and a start switch for first supplying power to one of the monitoring stations in response to a cab start signal. The monitoring station becomes the control station, and the switching circuits are sequentially closed to sequentially activate adjacent monitoring stations via the power supply line, and the position and operation information of the vehicle to which each monitoring station belongs is transmitted through the serial transmission line. Since the input is input to the monitoring station that serves as the control station via the train, it is possible to determine the connection relationship between each vehicle, distinguish each monitoring station, and accurately exchange monitoring information from the vehicle equipment in each vehicle. This has the effect of providing a monitoring device.
