Description

[Detailed Description of the Invention] This machine receives 1 train book number information, 1 train position information, etc. from an external device! The present invention relates to a train number display device that displays a train number on the display 11 of a monitoring panel in correspondence with the position of a train on a train route.

This type of device generally stores a train number input from a transmission device or a train schedule storage device in a predetermined window address of a storage circuit having a plurality of window addresses (memories S) individually corresponding to the display windows. , point occurrence information that means that train No. 11 has shifted its train number from the shift Chobekan point to the next point based on the train position information input from the train position detection device etc. via the transmission device, and the A point number that specifies the point is created by the point information creation circuit, and based on the point number, the window address (number of the window address of the shift source) that stores the train number to be shifted is created. and,
A number (destination window number) is created for the window address (shift destination window address) where the train number is newly stored, and the train information of the window address corresponding to the departure window number is made to correspond to the destination window number. is configured to shift to a window address that

However, in this type of device, if the transmission device continues to detect typos and a short train that is not specified runs, the point information creation circuit does not output the point information, and as a result, the shift source window address In some cases, the train number is not shifted correctly, but after this shift deviation occurs, when the train passes the next point information detection point, the conventional device will shift the train number to the window address corresponding to the starting window number. Without the number, the train number would not be shifted and the point information would be discarded as is, resulting in the disadvantage that the displayed state of the train number would not match the actual position of the train.

In the present invention, when there is no train number in the window address of the shift source even though the train number shift condition is met, the train number of the window address in the previous stage than the window address of the shift source is transferred to the window of the shift destination. Make sure to shift to the address.

An object of the present invention is to provide a train number display device capable of automatically correcting the display state of the actual train position and train number.

In FIG. 1, reference numeral 1 denotes a known input circuit that temporarily stores a train number input from an information transmission device or a train schedule storage device, and this time I! The train number temporarily stored in the train number 1 is read into the storage device 2 having a plurality of window addresses (memories S) individually corresponding to the display windows for the 30 rows of single honor codes on a display device such as a monitoring panel. This storage device 2 is a known device equipped with a writing function and a reading function, and writes the train number read from the % input circuit 1 into a predetermined window address. is output to the display device 3.

The display device 3 has display windows A, B, C, as shown in FIG.
D, E, etc. are provided sequentially along the train running route.

In Fig. 2, I, It, II, etc. indicate the points at which the train numbers should be shifted. Therefore, in this example, the storage device 2 stores the information from the display window ^ to B, from C, from D to f, -z. The shift of the train number is controlled by the shift control circuit 6, but the shift of the train number from display window B to C is controlled by the display window Ce.
As long as the c° train train number is not displayed, the train number is shifted by its own circuit.

Reference numeral 4 denotes a known input circuit that temporarily stores train position and route information inputted from the information transmission device.The train position and route information temporarily stored in this circuit 4 is read by the point information creation circuit 5, and this point information is read by the point information creation circuit 5. It is converted into point information in the creation circuit 5. The point information includes a point number C that specifies the position of the train (the point at which the train number should be shifted), and a point (occurrence) signal d that indicates that the train number shift condition has been met.
and are each supplied to a shift control circuit 6 that shifts the train number at a predetermined window address of the storage device 20 to the next window address.

Shift control cycle [6 is the first and second shift tables 10.11 and 12 which store pairs of start window numbers and destination window numbers for each point number, as shown in Figure 3.
．． 13°14.15, or gate 16, and memory 8I8
17 and a control circuit 18, the departure point window number stores the train number to be shifted. This is a number (address) that specifies the so-called shift destination window address to which the number is shifted.

The starting honorary code of the first shift table 10 is the number of the window address of the shift source during normal operation, that is, the window address number of the section one step before the shift control section of the window address of the shift destination, and the second The starting point number of the shift table 11 is the window address obtained by shifting one train number from the window address of the shift source, that is, the number of the window address of the section one step before the shift control section of the window address of the shift source. It is. Therefore, the first shift table 10 is as shown in FIG.
As shown in , pairs of starting window numbers ^, C, D, etc. and destination window numbers B, D, E, etc. are assigned to point numbers 1. I [, III...
・The second shift table 11 is made of rattan 4
As shown in Figure (II), the opening window number is 5, A.

Point I is the pair of C... and destination numbers B, D, E...

The starting window number and arrival window number in each shift table 10 are as follows:
When the corresponding point numbers are input as address signals, they are individually output to the AND gates 12 and 13, and the starting point number and destination window number in the second shift table 11 are inputted as address signals. As a result, they will be output individually on 14.15. anime game
) 12.13° and 14.15 are only shown in the figure, but in reality, the starting window number and the destination window number are each output in parallel, so the bits of the starting window number and the destination window number are There will be an equal number of

OR gate 16 is AND gate 12.1B.

14. The OR signal of the output signal of 15 is used as 111 for address.
The incense name is e, and it is a four-way output to the storage device 2, followed by c.
*@ltc is provided in the same number of bits as the window number.

The memory circuit 1617 is a circuit that temporarily stores the train number tube that has been read out from the storage device 3 under the control of the control circuit 18, and supplies the stored contents to the storage device 3 as the train number g for writing. The control circuit 18 starts operating when the point information d is input from the point information creation circuit 5, searches the shift table using the point number C, and inputs the information to the AND gate 12, as shown in the fifth aiilK. The signal is outputted to the first shift table 102 as the starting window number V window number e, and a read command J is output to the storage device 2, and the window specified by the starting window number is outputted to the storage device 2. The content of the address f11 is stored in the memory circuit 17, and it is determined whether or not there is a train number in the start window address. As a result of this determination, if the train number is present, normal shift control is performed. In this normal shift control, first, a signal of 1v is output to the AND gate 13, and the first
outputs the arrival point window number of the shift table 1o to the storage device 2 and also issues a write command m! t, is output to the memory device 2 and then cleared to the memory circuit 17, and then the signal hvtb is input to the AND gate 12 to output the arrival point window number of the shift register 10 of 1s1 to the memory device 2, and a write command mt is stored. This is control for outputting to the device 2 again.

As a result, the memory [1112] writes the contents of the memory circuit IT to the window address corresponding to the window number e every time the write command m is input, and therefore the train number of the shift source window address is changed to the train number of the shift destination window address. address, and the source window address is cleared. In other words, the point number is ■
As is clear from Fig. 3 (4), the train number in the display window OK display window C in Fig. 2 is displayed on the Noto trunk.
The train number on the IC will be deleted.

As a result of the above judgment, if there is no train number in the window address of the shift source, the control diagram j118 outputs a signal Jv to the anime game) 14 and sets the starting window number of the second shift group 110 as the window number e in the storage device 2. The contents of the window address specified by the departure window number are stored in the memory circuit 17, and a judgment is made as to whether or not there is a train number at the corner window address. As a result of this determination, if there is no train number, the pulley, rung, etc. are driven to notify that there is an abnormality, and if there is a train number, shift control is performed in the event of an abnormality.

Shift control in the event of an abnormality involves sending signals to the AND gates 12 and 13, and instead of outputting 1 to the AND gates 14 and 15, a signal 1. Except for outputting k, this is the same as the left control during normal operation described above. As a result, the train number of the shift source window address at the point one step before the shift source window address in normal conditions is written to the shift destination window address.ttL, and the contents of the shift source window address at the point one step before are When the 0 station is cleared, that is, the point number is ■, the train number in the 1 display window A is displayed in the display window O, as is clear from the car in Figure 5 (B), and the train number in the display window A is will be deleted.

Furthermore, as is clear from Fig. 5 (4) and (B), since the arrival point window numbers of both shift doubles 10 and 12 are the same,
The arrival window number of the first shift table 10 can be used even in the event of an abnormality, and the arrival window number of the second shift table 10 and the AND gate 15 can be omitted.

As described above, the present invention provides a second shift table for backup, and when there is no train number at the shift source window address during normal operation, the train number at the shift source window address at a point one stage before that point is provided. Since the train is shifted by t, the difference between the display state of one train number and the train position at * can be automatically corrected during shift control.
