There is.

c.Means for solving problems] FIG. 1 is a block diagram of the principle of the present invention.

In the figure, 70 and 71 are line control circuits that receive the monitoring information of a plurality of terminal systems transmitted on the highway and send the monitoring information to the bus 72 at a time slot determined for each terminal system, and 74 is a line control circuit. Control circuit 70.71
An address creation section 75 receives an address from the address creation section 74 and sends it to each terminal from the memory section 25. This is a display control unit that reads system monitoring information in a fixed order and sends it to a display device.

[Effect]

Monitoring information from a plurality of terminal systems is time-division multiplexed and received by the line control circuits 70 and 71 via the highway, but even faster time-division multiplexing is performed to serially send the outputs of the plurality of line control circuits to the bus 72. can be sent with 0 for example 2
The monitoring information of a plurality of terminal systems received by the line control circuit 70.71 on a highway having a transmission rate of 4 MBPS can be serially assigned to specific time slots on the bus 72 having a transmission rate of 4 MBPS.

The address generation unit 74 uses address signals sent from the line control circuits 70 and 71 for each specific time slot,
By creating an address of the memory section 25 where monitoring information is recorded for each terminal system and sending the address to the memory section 25, the monitoring information assigned to that time slot is recorded.

The display control unit 75 inputs the above address to the address creation unit 74.
, and sets the display timing to a specific time slot other than the time slot assigned to the monitoring information, and reads the monitoring information of each terminal system from the memory unit 25 at a low speed via the bus 72 in the order of the terminal system number, for example. The monitoring information is sent to a display device and displayed.

Thus, a monitoring device that does not require a register to store monitoring information in the line control circuit, nor does it require a microprocessor or fixed memory, and can display monitoring information in a fixed order using a simple circuit with a small amount of hardware. is realized.
