[Industrial application field]

The present invention relates to a display control system, and particularly to a display control system that processes many types of line switching information and displays a line switching route on a line switching display section.

When a line is switched using line switching information, the display may show where the line was switched from to where, but if there are many types of line switching information, the processing of this switching information and the switching route A large-scale processing unit is required to display the image.

Therefore, there is a need for a display control method that is inexpensive and can be implemented with a simple circuit configuration.

[Conventional technology]

FIG. 1 is a diagram for explaining the line switching system.

Generally, when switching lines, the following switching information is required.

(1) Switching information between the working line and the protection line, etc. (2) Switching information between the station side and the line side, etc. (3) No. information of the line to be switched. This is switching information to switch to line No. 60 on the track side. When switching lines using this line switching information, the display may display the information from where to where the line was switched, but if there are many types of line switching information, processing and switching of this switching information may be necessary. A large-scale processing unit is required to display the route.

In FIG. 1, for example, it is assumed that the number of lines to be switched, 96×96, is divided and controlled by six switching devices No. (1) to No. (6) as follows. That is, the device (1) switches between the lines No. 1 to No. 48 on the station side and the lines No. 1 to No. 32 on the track side.
(6) Lines No. 49 to No. 96 on the station building side and No. 65 to No. 96 on the track side
(This is called setting information) so that each line is divided and the line switching is controlled.

Now, in the case of line switching such as →, when information regarding line switching (hereinafter referred to as input information) is input, this input information is added to all six processing devices. Therefore, each of the processing devices (1) to (6) determines whether this input information is relevant to its own location by comparing it with the setting information.

If the input information is information related to your location, it is determined from where to where it will go, and the determination result is stored in a memory (not shown) provided for each processing device (1) to (6). Write. The written route is immediately read out and displayed on a display unit (not shown) (for example, by lighting an LED).

On the other hand, a processing device that determines that the input information is not relevant to itself does not perform any processing.

Conventionally, this determination has been made using a logic circuit (not shown) constructed of a NAND circuit (not shown) or the like.

[Problem to be solved by the invention]

However, in the display control method described above,
Previously, input information and setting information were used to determine which path to take for each switching combination using a logic circuit, but one NAND circuit with 3 to 4 inputs was required to determine one switching pattern, and the above In the example case 3-4
Approximately including the input NAND circuit and its attached circuit
200 TTL (transistor-transistor-logic) gates were required.

Therefore, there were problems in that the circuit configuration became complicated, the price was high, and the reliability decreased.

Therefore, an object of the present invention is to provide a display control method that is inexpensive and can be implemented with a simple circuit configuration.

[Means to solve the problem]

The problem mentioned above is that in the display control method of a device that has the function of processing multiple line switching information and displaying a line switching route, information indicating the on/off switching line number and the range of switchable line numbers of the device A read-only system that inputs the comparison information in binary display obtained by comparing the information indicating on the track side, and combines the input information regarding on/off, converts it to the first binary information, and outputs it. Input in memory 1 the comparison information in binary notation obtained by comparing the information indicating the on/off switching line number and the information indicating the range of switchable line numbers of the device on the station side. A read-only memory 2 that combines input information related to on/off and converts it into first binary information and outputs it, and a second read-only memory that inputs the outputs of read-only memories 1 and 2 and combines them. The read-only memory 3 converts and outputs binary information, and the input read-only memory 3 inputs the combination information of the output of the read-only memory 3 and the on/off information of the working/protection line. - After adding combination information of working/protection line on/off information corresponding to the line switching state to the output of memory 3, it is converted to third binary information and separated into the line side and station side. Output read-only memory 4, 5, 6,
7, and the third binary information output from the read-only memories 4, 5, 6, and 7 controls the display unit 10 via the memories 8 and 9. This is achieved by

[Effect]

Comparison of binary numbers obtained by comparing information indicating on (switching) and off (disconnecting) line numbers and information indicating the range of line numbers that can be switched by equipment for the track side and the station building side, respectively. Input the information into read-only memories 1 and 2,
The read-only memories 1 and 2 combine input information regarding on/off, convert it into first binary information, and output it.

As a result, it is sufficient to use, for example, six input lines (6 bits) and four output lines (4 bits, 9 types) in each of the read-only memories 1 and 2.

Next, input the outputs of read-only memories 1 and 2 to read-only memory 3, and
The only memory 3 combines the two and converts it into second binary information (for example, 7 bits, 81 types of information) and outputs it.

Output and current use of read-only memory 3 above
The combination information of the on/off information of the protection line is input to the read-only memories 4, 5, 6, and 7, and the current use corresponding to the line switching state is input to the output of the input read-only memory 3. /After adding the combination information of the on/off information of the protection line, it is converted into third binary information and output separately to the line side and the station side.

And read-only memory 4, 5, 6,
The third binary information of the output of 7 causes the memory 8,
The display unit 10 is controlled via 9.

As a result, by using several read-only memories, an inexpensive and highly reliable circuit can be obtained with a simple circuit configuration.

〔Example〕

FIG. 2 is a block diagram showing the configuration of an apparatus according to an embodiment of the present invention.

In the figure, 1 to 7 are read-only memories (hereinafter referred to as
8 is the station side memory, 9 is the track side memory, 10 is the display section, 11 is the track side comparison input information, 12 is the station side comparison input information, 1
3 indicates on/off information of the combined working and protection lines, and 14 to 17 indicate terminals, respectively.

Further, an example of information input to each device is shown below.

A: On number information on the station building side, B: Off number information on the station building side, C: On number information on the track side, D: Off number information on the track side, E, F: Current or backup on information, G , H: Current or standby off information, Setting information for own equipment, X: Setting information for the track side of own equipment, For example, in the case of equipment (1) or equipment (2) shown in Figure 1, X is No. Shows the range from 1 to No. 32. Similarly, in the case of device (3) or device (4), X is the range from No. 33 to No. 64, and in the case of device (5) or device (6),
indicates the range from No. 65 to No. 96.

Y: Setting information on the station side of the own device. For example, in the case of device (1), device (3), or device (5) shown in FIG. 1, Y indicates the range from No. 1 to No. 48. Similarly, in the case of device (2), device (4), or device (6), Y indicates the range from No. 49 to No. 96.

Figure 2 shows the circuit configuration used in each of devices (1) to (6) shown in Figure 1, and shows the ROM
1. ROM2 has 6 input lines each ~,
′ to ′ (not shown) are connected.

For example, in the input line ~ of ROM1, the previous stage circuit (not shown) compares the line side setting information X of the own device with the line side on number information (on line connection number) C. The obtained signal (indicated by "1" or "0") is input.

For example, on the input line, when the value of C is larger than the range given by X (temporarily written as X<C), "1" is written.
In other cases, input "0". Similarly, "1" is input to the input line when the value of C is smaller than the range given by X (X>C), and "0" is input otherwise. Also, input "1" into the input line when the value of C is included in the range given by X (C=X), and "0" when the value of C is not included in the range given by X. .

Regarding the input lines ~ of ROM1, in the same way as described above, in the previous stage circuit (not shown),
and track side off number information (off line connection number)
The signal obtained by comparing with D (“1” or “0”
) is input.

For example, on the input line, when the value of D is larger than the range given by X (temporarily written as X<D), "1" is written.
In other cases, input "0". Similarly, "1" is input to the input line when the value of D is smaller than the range given by X (X>D), and "0" is input otherwise. Also, input "1" into the input line when the value of D is included in the range given by X (D=X), and "0" when the value of D is not included in the range given by X. .

Now, assuming that the device shown in FIG. 2 represents the device (1) shown in FIG. 1, the setting information X on the line side indicates the range of No. 1 to No. 32 as described above. Therefore, for example, on-number information on the track side (i.e., line number to be connected) C
For example, when the line side off number information (that is, the line number to be disconnected) D is 11, that is, when line No. 10 on the line side is newly connected and No. 11 is disconnected, No. 10, No. 11 are both in the range of X (No.1
~ No. 32), so the input line of ROM1 is "1", and the input line ~ is (001001).
It is entered in the form of

Also, when the on number information (i.e. the line number to be connected) C on the track side is, for example, 35, and the off number information (i.e. the line number to be disconnected) D on the track side is e.g. 38, the values of C and D are as shown in Figure 1. It belongs to device (3) shown in the figure, and is larger than the X range (No. 1 to No. 32) of device (1), so the input line of ROM1 is "1", and the input line ~ is (100100). It is entered in the form of

Then, input the line-side comparison information (for example, information consisting of 6 bits) of the bit pattern according to the above-mentioned certain rules to the input line ~ of ROM1,
The ROM 1 converts nine types of output signals obtained as a combination (product) of three C and D inputs into four binary signals and outputs them.

In addition, the above-mentioned on/off number information C on the track side
Alternatively, the value of D (for example, No. 10, 11 or No. 35, 38 as C, D) is added to the display section 10 at the same timing as data stored in the RAM 9, which will be described later, is read out and added to the display section 10.

Next, the station side comparison information input to the ROM 2 shown in FIG. 2 will be explained in the same manner as the line side comparison information described above.

That is, six input lines ' to ' (not shown) are connected to the ROM 2 . For example, among the input lines '-' of the ROM2, '-' are provided with setting information Y on the station side of the own device and on-number information (line number to be connected) on the station side in the previous stage circuit (not shown).
The signal obtained by comparing with A (“1” or “0”
) is input.

For example, when the value of A is larger than the range given by Y (temporarily written as Y<A), "1" is input to the input line '.
In other cases, input "0". Similarly, "1" is input to the input line' when the value of A is smaller than the range given by Y (Y>A), and "0" is input otherwise. In addition, the input line' indicates "1" when the value of A is included in the range given by Y (A=Y);
“0” when the value of is not included in the range given by Y
Enter.

Similarly to the input lines '~' of ROM2, in the previous stage circuit (not shown),
Off number information on Y and station side (line number to be disconnected)
The signal obtained by comparing with B (“1” or “0”
) is input.

For example, when the value of B is larger than the range given by Y (temporarily written as Y<B), "1" is input to the input line '.
In other cases, input "0". Similarly, "1" is input to the input line ' when the value of B is smaller than the range given by Y (Y>B), and "0" is input otherwise. In addition, the input line' indicates "1" when the value of B is included in the range given by Y (B=Y);
“0” when the value of is not included in the range given by Y
Enter.

As in the case of the ROM 1 described above, if the device shown in FIG. 2 represents the device (1) shown in FIG. 1, the setting information Y on the station side indicates the range from No. 1 to No. 48. Therefore,
For example, when the on-number information (i.e., the line number to connect) A on the station side is 5, and the off-number information (i.e., the line number to disconnect) B on the station side is 6, for example,
In other words, when line No. 5 on the track side is newly connected and No. 6 is disconnected, both No. 5 and No. 6 are included in the range of Y (No. 1 to No. 48), so the input of ROM2 The lines ′ and ′ become “1”, and input lines ′ to ′ are input in the form of (001001).

Also, when the on-number information (i.e., the line number to connect) A on the station side is, for example, 50, and the off-number information (i.e., the line number to be disconnected) on the station side is, for example, 60, the values of A and B are the first Since it belongs to the device (2) shown in the figure and is larger than the Y range (No. 1 to No. 48) of device (1), the input lines ' and ' of ROM2 are "1", and the input lines ' to ' is input in the form (100100).

Then, the station side comparison information (for example, information consisting of 6 bits) of the bit pattern according to the above-mentioned certain rules is input to the input lines '~' of the ROM2,
The ROM 2 converts nine types of output signals obtained as a combination (product) of these three inputs for each of A and B into four signals expressed in binary numbers and outputs the signals.

In addition, the above-mentioned on/off number information A on the station side
Alternatively, the value of B (for example, No. 5, 6 or No. 50, 60 for A and B) is added to the display section 10 at the same timing as data stored in the RAM 8, which will be described later, is read out and added to the display section 10.

Further, information indicating whether the line-side comparison information and station-side comparison information inputted to the ROM1 and ROM2 described above are for the working line or the protection line is inputted to the ROM4 to ROM7 described later.

The X, C,
The combination information of D, Y, A, and B is input to the ROM 3, and the ROM 3 generates 81 types of output signals (9 x 9 =) obtained by combining the track side information and the station side information, for example, in 7 bits (7 The signal is converted into a binary representation signal consisting of 1) and output.

The output of this ROM3 is branched and applied to one input terminal of ROM4-7. The other input terminals of ROM4 to ROM7 contain the on information (E, F) of the working or protection line, or the off information of the working or protection line, regarding the track side comparison information and station side comparison information input to ROM1 and ROM2. Information (G, H) is added as, for example, four signals (16 types) in binary representation.

That is, the four input lines added to each of ROM4 to ROM7 are ``~'' (not shown),
For example, "" corresponds to E, "" corresponds to F, "" corresponds to G, and "" corresponds to H. For example, when the line-side comparison information input to the ROM 1 connects (turns on) the working line, it is input in the form of (1000) to the input lines "~".

In ROM4 to 7, track side information (9 types)
For example, by combining the information on the station side (9 types),
For signals converted to binary representation consisting of bits (7 bits, 81 types), on information (E, F) or off information (G, H) (16 Obtain a signal expressed in binary with the addition of the type (type). That is, as a combination (product) of both inputs, 81×16=1296 types of signals expressed in binary numbers are obtained.

Then, among the binary display signals related to the station building side, a signal that lights up the switching route display LED (i.e.,
For example, the signal to connect the line) is from ROM4, and the signal to turn off the light (signal to disconnect the line) is from ROM6.
, and write it to RAM8 for temporary storage. Similarly, among the binary display signals related to the track side, the signal that lights up the switching route display LED (that is, the signal that connects the line) is, for example, ROM5
Then, the signal goes out again (signal to disconnect the line).
It is read from ROM7 and written to RAM9 for temporary storage.

In addition, the above lighting information and lighting information are stored in each ROM 4 to 7.
Either one is selected by a control signal applied to the chip selector terminal CE.

After that, the signal for displaying the connection route written in the above-mentioned RAMs 8 to 9 and temporarily stored is read out and sent to the display section 10.
An LED (not shown) is turned on or off to indicate the connection route.

Also, as mentioned above, the line number corresponding to the connection path is branched from the signals input to ROM1 and ROM2 and inputted to the display unit 10, and in this case, the line number related to the device 1 shown in FIG. 1 is displayed. Display the included connection routes.

Device (2) shown in Figure 1 that displays the route as described above.
~Do this also for device (6). And finally the device
Displays the entire connection path including (1) to device (6).

As a result, the conventional hardware that required approximately 200 TTL gates (approximately 5 in a small package) can be realized with just a few read-only memories (one small package). The hardware will be 1/5th.

Therefore, it is possible to obtain an inexpensive and highly reliable circuit with a simple circuit configuration.
