Description

[Detailed description of the invention]

The present invention relates to a console control device, and more particularly to a console control device that controls information transmission between a central control device and a console. When a central control device such as an electronic exchange advances processing according to a program, the subsequent processing steps may be changed depending on the operating state of a branch switch provided in the console. FIG. 1 is a diagram showing an example of a conventional method in which the central controller refers to the operating status of a branch switch. In FIG. 1, console B is provided with 16 branch switches D0 to D15. Each branch switch Di (i is 0 to 15) has three operating states, which are respectively referred to as an ON state, an OFF state, and a STOP state. The operating state is input to the console control device A by the operation signal b for each branch switch and is stored therein. The central controller C switches the branch switch D0 according to the program.
When the central control unit C executes the instruction 0 that changes the processing process depending on the operating state of A set of three target operating states is referred to as a branch switch unit.) The console control device A outputs the stored operating state of the designated branch switch D0 as an operating state output signal.
A combination of logical values as shown in the do and ds table is transmitted to the central controller C. The central controller C receives the received operating status.

[Table] When the output signals do and ds indicate the ON state, jump to instruction 2 of the program and execute it.
Further, when the OFF state is indicated, instruction 1 of the program is executed, and when the STOP state is indicated, the operation is stopped. As is clear from the above explanation, in a conventional console control device, in order to execute 16 types of instructions 0, 16 branch switches D0 to D1 are required.
5, the required dimensions of the console B become larger, and the price also increases. Particularly when a non-locking switch such as a seat key is used, two non-locking switches are required for one plant switch, and the above-mentioned drawbacks are further exacerbated. SUMMARY OF THE INVENTION An object of the present invention is to eliminate the drawbacks of conventional console control devices as described above and to reduce the number of branch switches on the console as much as possible. This purpose is to provide a console control device that controls information transmission between a central control device and a console with an operation signal input from the console that displays the branch switch type, an operation signal that displays the branch switch unit, and an operation signal that displays the branch switch unit. A storage means is provided for storing an operation signal indicating the operating state of each branch switch, and by receiving a signal specifying a branch switch unit from the central control device, the specified branch switch unit stored in the storage means is stored. This is achieved by outputting the operating status of the An embodiment of the present invention will be described below with reference to FIGS. 2 to 5. FIG. 2 is a diagram showing an example of an electric keyboard of a console used in conjunction with a console control device according to an embodiment of the present invention, and FIG. 3 is a diagram showing the configuration of a console control device according to an embodiment of the present invention. , FIG. 4 is a diagram showing the configuration of a console control device according to another embodiment of the present invention, and FIG. 5 is a signal sequence diagram in FIG. 4. In Fig. 2, switches D, X, Y, and Z are switches for specifying the input switch type, switch D is a switch type for branch switch types, and switches X, Y, and Z are switches for specifying other switch types. . Switch E specifies the switch unit within each switch type, and switch F specifies the status of each switch unit. Therefore, by operating the switches E0 to E15 after operating the branch switch D, 16 branch switch units D0 to D1 can be set.
5 is specified. After specifying the branch switch unit Di (i is 0 to 15), further switch F0, F
By operating 1 or F2, the branch switch unit Di is set to OFF state, ON state or
Set to STOP state. Each of the above switches D,
Each time E0 to 15, F0, F1, and F2 are operated, an operation signal b is input from console B to console control device A. In FIG. 3, when the operation signal b of the switch D is input from the console B, the switch signal generation circuit AA of the console control device A operates, outputs the signal d, and at the same time activates the time limit circuit AB. Time limit circuit AB outputs a setting signal td for switch D at a predetermined time. Flip-flop inputted with signal d and setting signal td
AD becomes set state. Next, when the operation signal b for the switch E0 is input from the console B, the switch signal generating circuit AA operates, outputting the signal e0, and at the same time outputs the setting signal te for the switch E from the timer circuit AB. The result is a flip-flop
AC0 enters the set state. By the output of flip-flop AD and AC0 which are in the set state,
Gates AG0 and AH0 become conductive. Furthermore, when the operation signal b of the switch F1 is input from the console B, the switch signal generating circuit AA operates and outputs the signal f0, and at the same time causes the time limit circuit AB to output a setting signal tf for the switch F. As a result, flip-flop AE0 enters the set state.
As described above, the ON state of the branch switch unit D0 is stored in the console control device A by bringing the flip-flop AE0 into the set state and flip-flop AF0 into the reset state. In the console B, the number 1 is displayed on the display G0, indicating that the ON state of the branch switch unit D0 is stored in the console control device A. However, in FIG. Circuits are omitted. In such a state, the branch switch unit D is transferred from the central controller C to the branch switch unit D.
When branch switch unit designation signal c0 arrives in order to refer to the operating state of flip-flop 0, 16-1 selection circuits AI and AJ of console control device A select flip-flops AE0 and AF0, corresponding to flip-flop AE0 in the set state. The operating state output signal do has a logic value of 1, and it also has a logic value of 0 corresponding to the flip-flop AF0 in the reset state.
The operating state output signal ds of is outputted to the central control device C. As is clear from the above description, according to this embodiment, switches D, E0 to E15 and F0, F
1 or F2, the operating states of the 16 branch switch units D0 to D15 can be stored in the console control device A, and can always respond to references from the central control device C. Note that switches E, F and display G shown in Fig. 2 are also used for types other than branch switches; only switch D is provided exclusively for branch switches; It contributes to economicization and economicization. Note that FIG. 3 is only one embodiment of the present invention, and for example, each branch switch unit D0 to D1
A flip-flop is used as a means to store the operating status of 5.
Instead of using AE0 to AE15 and AF0 to AF15, it is also conceivable to use more economical storage devices. FIG. 4 is a diagram showing the configuration of a console control device according to another embodiment of the present invention using this storage means. In FIG. 4, the first storage section
AN and second memory AO are branch switch D
It is provided as a storage means for 0 to D15.
As mentioned above, from console B to switches D and E
After the operation signal b of switch F1 is input and the flip-flops AD and AC0 are set by the operation of the switch signal generation circuit AA and time limit circuit AB, when the operation signal b of switch F1 is further input, the switch signal generation circuit starts. The signal f0 from circuit AA is
Further, a setting signal tf is output from the time limit circuit AB.
The output of the flip-flop AD in the set state,
The gate AR to which the setting circuit tf is input is the signal ts
The sequence of various signals output by the control circuit AS that starts the control circuit AS is shown in FIG.
In FIG. 5, the control circuit activated at time t0
AS outputs signals tl and tm, and sets both 2-1 selection circuits AL and AM to the input S side. At time t1, the signal tl stops and the 2-1 selection circuit AL is set to the input r side. Therefore, the output of the flip-flop AC0 in the setting state is output to the encoding circuit.
After being encoded by AK, 2-1 selection circuit AL
The address information is input as address information to terminal a of the first storage unit AN. On the other hand, the signal fo output from the switch signal circuit AA is input as write information to the terminals io of the first storage section AN and the second storage section AO. At time t2, the control circuit AS inputs the signal tn to the terminal WE of the first storage part AN, and based on the address information input to the terminal a, the control circuit AS inputs the signal tn to the terminal WE of the first storage part AN, and inputs the signal tn to the terminal io and is based on the address information input to the terminal a.
The signal fo (logical value 1) and the signal input to
Write fs (logical value 0). Next, at time t3,
The control circuit AS sends out the signal tl and stops the signal tm. As a result, the 2-1 selection circuit AL is set to the input S side, the 2-1 selection circuit AL is set to the input S side, and the 2-1 selection circuit AM is set to the input r side. Therefore, the output of the encoding circuit passes through the 2-1 selection circuit AM,
By inputting address information to terminal a of the second storage unit AO and inputting signal to at time t4,
Writing is performed in the same manner as in the first storage part AN. On the other hand, when the branch switch designation signal c0 arrives from the central control device C in order to refer to the operating state of the branch switch unit D0, it is sent via the 2-1 selection circuit AL or AM set on the input S side.
The address information is input to the terminal a of the first storage unit AN or the second storage unit AO and read out, and the signal
Write information (logic value 1) by fo is output to the terminal oo, and write information (logic value 0) by the signal fs is output to the terminal os. However, the 2-1 selection circuits AP and AQ are both set to the input r side when the signal tp is not input from the control circuit AS, so the output from the terminal oo of the first storage section AN is 2. -1
The operating state signal do is output to the central control unit C via the selection circuit AP, and the output from the terminal os of the first memory section AN is output to the central control unit C via the 2-1 selection circuit AQ as the operating state signal ds. It is output to device C. In addition, when the reference from the central controller C is from time t3 to t5, the signals fo and fs indicating the operating state of the branch switch unit D0 as described above are stored in the second storage unit AO due to the stop of the signal tm.
is written, but does not have any adverse effect on the output of the operating state output signals do and ds. Furthermore, when the operating state of the branch switch unit D0 is referenced from the central controller C from time t1 to t3, the 2-1 selection circuits AP and AQ are both set to the s side by the input of the signal tp. , the outputs from the terminals oo and os of the second storage unit AO are outputted to the central controller C as operating state output signals do and ds via the 2-1 selection circuits AP and AQ. Meanwhile, due to the stop of the signal tl, the above-mentioned branch switch unit D0 is stored in the first memory section AN.
Although the operating state is written, there is no adverse effect on the output of the operating state output signals do and ds. Note that, similar to FIG. 3, the display related circuits are omitted in FIG. 4 as well. Furthermore, in FIGS. 3 and 4, the number of branch switch units is not limited to 16, and even if the number of branch switches is arbitrary, the effects of the present invention can be achieved by appropriately selecting the number of switches D and E. remains unchanged. As described above, according to the present invention, there is no need to provide the same number of branch switches in the console as there are branch switch units that the central control unit refers to in order to change the processing process, and only a small number of dedicated switches can be provided. This will help make consoles more compact and economical.
