Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a switchboard control device, and more particularly to a switchboard control device having a switchboard monitor function.

[Conventional technology]

Conventionally, this type of switchboard control device only had the function of controlling the transfer of information between the host 1 to the processor and the switchboard, and the function of displaying the switchboard screen in response to the operator's key operations without involving the host processor. Ta.

[Problem that the invention seeks to solve]

In the above-mentioned conventional switchboard controller, when a switchboard monitors another switchboard, when the host processor recognizes a change in the screen of the monitored board by a notification from the switchboard controller, the host processor And the switchboard control device performed the following processing.

That is, the host processor sends an instruction to the switching board control device to read all printed characters on the screen of the monitored board. Upon receiving this reading instruction, the switching console controller reads the entire screen information of the monitored console and transfers the entire screen data to the host processor.

Next, the host processor issues a full-screen write instruction to the switchboard control device in order to send the full-screen data returned by the read instruction to the monitor stand. The switching board control station that receives this write instruction sends full screen data to the monitor board.

In order to perform the monitoring in this way, the host processor needs to instruct the above-mentioned reading of all printed characters and write the entire screen, which has the drawback of affecting its processing performance. Furthermore, when the switchboard control device and the switchboard are installed remotely, there is a drawback that the information transfer speed between the host processor and the switchboard control device is a factor that affects the response delay of the monitor stand.

[Means for solving problems]

The switchboard control device of the present invention has an information transfer function between a host processor including a main storage device and a switchboard, and a switchboard screen display function in response to an operator's switchboard key operation without the involvement of the host processor. In the platform control device, a reception buffer that receives information from the host processor, a transmission buffer that transmits information to the host processor, a switchboard interface circuit that transmits and receives information to and from each of the switchboards, and each of the switchboards. The switchboard status memory stores the information displayed on the screen and the flashing status of the lamps, and the processor has a switchboard monitor control function that identifies the monitor of the switchboard.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the switching board control device of the present invention.

In the figure, a switchboard controller (hereinafter referred to as PCTL) 1 includes a host processor (not shown) including a main memory (not shown).
Hereinafter CC) 2 and multiple switchboards (hereinafter PO3o, ~P

It is equipped with a screen display function that displays the screen of a desired switchboard among the switches 30, 3, and 3m. The PCTLI includes a reception bar sofa (hereinafter referred to as R) 10 that receives information from the CC2;
A transmission buffer (hereinafter referred to as 5) 11 that transmits information to the CC2, a switchboard interface circuit (hereinafter referred to as ■) 12 that transmits and receives information to and from each of PO3, 30, to PO3, 3m, and Po8o30. ~ Switchboard status memory (hereinafter referred to as PM>13, RIO, Sll
, 112. The processor (hereinafter referred to as P) 14 performs predetermined control of the PM 13 and identifies the switchboard monitor.

Next, the operation of this embodiment will be explained using FIG. 2.

FIGS. 2(a), (b), and (c) are block diagrams for explaining the operation of the switchboard control device in FIG. 1. It shows the progress of the operations of P M 13 and PI 3 during monitoring. Note that PM13 has a memory area for PO8o (hereinafter referred to as Ao>130 and a memory area for pos (hereinafter referred to as A+) 1
31 are provided.

The PCTLI (shown in Figure 1) is
PO3n can be used as a monitored stand by key operation of 3n30.
When PI3 recognizes that PO3n30 has been designated, it stores the switchboard number of PO3n30 in a built-in memory (not shown) using the switchboard monitor identification function described above. next,
As shown in FIG. 2(a), in order to match the screen display and lamp display contents of PO3, 31 with those of PO3, 30, PI3 is A. The contents of 130 are transferred to A and 131. After that, P14 reads the contents of A1131 and
2 to Po5t 31. Therefore, at this point, the screen displays of PO3n30 and PO3l31 and the lighting/flashing status of the lamps match. Also, PI3 is S
ll to CC2 (shown in Figure 1), monitor stand PO
3+31 specifies the monitored stand poso 30, which is read from the memory and notified. Note that PCTLl stores information associated with key operations on each switchboard by the operator at 112.
CC2 is constantly monitored via Sll, and the information that needs to be notified to CC2 is transferred via Sll. C.C.
2 analyzes and processes this information and, if necessary, sends the processed data to pCTLl for display on the switchboard.

If the switchboard to be displayed here is PO8°30 of the monitored board, as shown in Figure 2(b), if the RIO is the CC
After receiving the data of the processing result of step 2, PI3 reads the contents of RIO and sends it to poso 30 via 112, and writes this contents to A0130. After that, p14 determines whether the switchboard to be displayed is PO3030 using the switchboard monitor identification function, and
When it is determined that it should be displayed on Ao13, PI3
After transferring the contents of 0 to A113.1, A sends the contents of 1:31 to PO3+31 via 112.

Furthermore, if it is not necessary for PCTLl to transfer the information associated with the key operations of each switchboard received via 112 to CC2, the key operation information at PO3, 30 is transferred to the screen as shown in FIG. 1 if you need to echo back to
After echoing back to PO8°30 via PI
3 is A. The screen data is written to 130. after that,
PI3 uses the switchboard monitor identification function to identify poso.
When it is determined that the content should be displayed on PO3+30, the content of Ao130 is transferred to A+131 as in FIG. 2(b), and then the content of A1131 is sent to PO3+31 via 112.

〔Effect of the invention〕

As explained above, in the present invention, the status of the monitored board can be transferred and displayed on the monitor board through the processing within the switching board control device, so that the processing capacity of the host processor is prevented from decreasing, and the monitor board can immediately Since it is possible to respond, it has the effect of preventing delays in response time.
