Abstract

PURPOSE:To improve the operability of a system monitor device by storing previously the switch information showing definitely the switch state data on a switch device and executing an indicated switching action just by indicating a discrimination address from an operation board. CONSTITUTION:In a register mode of the rewriting information, the switch information is delivered to a signal line 5 from an operation board 1 together with a discrimination address corresponding to a signal line 4. At the same time, the switch information is stored to a memory circuit 18 via an AND gate 8 in the form of the write data by a switch information registration indicating signal. Then a switching action is indicated through the board 1, and a switch action signal is delivered onto a signal line 3. At the same time, the discrimination address signal set on the board 1 is also delivered to the line 4 for selection of the switch information registered to the circuit 18. Then the read data is delivered as the switch information read data from the circuit 18 to a switch device 17 via a switch control circuit 15. Thus a manual switching action is possible.

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a system monitoring device for monitoring the operation of an information processing system, and more particularly to manual switching control of a switching device during supervisory control.

(Prior Art) Conventionally, manual switching control of input/output devices and switching devices that determine connection of lines in this type of system monitoring device was performed on the operation panel of the system monitoring device.
A plurality of changeover switches were operated to be set to predetermined connection positions depending on the operation of the system.

(Problems to be Solved by the Invention) In the above-mentioned prior art, the operation mode of the system is set by repeating limited combinations. However, there was an operational drawback in that switching information for determining connections for all switching modes existing in the system had to be input from the operation panel using a changeover switch each time.

An object of the present invention is to register the switching information of the above-mentioned changeover switch in a memory circuit by manual input from the operation panel, and to identify the registered changeover information when starting the manual changeover of the changeover switch. By simply instructing the identification address added for the purpose of switching from the operation panel, the switching control signal is read out from the memory circuit and supplied to the switching control circuit to realize the instructed switching operation, thereby solving the above drawbacks. An object of the present invention is to provide a system monitoring device configured to remove the problems and improve operability.

The switching device is for determining the connection between the information processing devices.

The switching control circuit is for controlling the switching device.

The memory circuit is for registering a plurality of pieces of switching information indicating the connection state of the changeover switch inside the switching device according to the operation of the system.

The address register is a register that stores an identification address added to identify switching information and enables writing/reading to/from the storage circuit.

The data register is for storing switching information read from the storage circuit and supplying it to the switching control circuit.

The operation panel is used to intervene and start the switching operation based on the switching information, register the input and switching information in the storage circuit, and instruct the content of the switching information and the value of the identification address.

(Example) Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of a seven-stem monitoring device according to the present invention. In Fig. 1, 1 is an operation panel;
6 is an address register, 8.9 is an AND gate, 13 is a data register, 15 is a switching control circuit, 17
is a switching device, 18 is a memory circuit, 2 to 5, 7, 9, 11
．． 12 and 1416 are signal lines, respectively.

In FIG. 1 showing an embodiment of the present invention, a switching device 17 in which a changeover switch is mounted is a switching control circuit 15.
It is controlled by the switching instruction signal from. When the changeover of the changeover switch is instructed from the operation panel 1 and a changeover operation instruction signal is outputted via the signal line 3, the switch is specified by the changeover information identification address supplied from the operation panel 1 via the signal line 4. The switching information is read from the address of the storage circuit 18 and stored in the data register 16. The switching control circuit 15 controls the switching device 17 based on this switching information.

First, the operation of registering switching information to which a switching information identification address is added from the operation panel 1 to the storage circuit 1B will be described. Registration of switching information in the memory circuit 18 is started when registration of switching information is instructed by the operation panel 1.
A switching information registration instruction signal is output from the signal line 2 to the signal line 2.

At this time, an identification address value is set on the operation panel 1 in accordance with the registered switching information, and the switching information on the signal m5 and the switching information identification address on the signal line 4 are output from the operation panel 1. The switching information identification address on the signal line 4 is stored in the address register 6, and is stored in the storage circuit 1 for registration.
When writing to 8, a storage address is given via signal line 7. The switching information on the signal line 5 is input to the AND gate 8, and when a switching information registration instruction signal is sent onto the signal line 2, the AND gate 8 enables output. Therefore, the switching information is written to the memory circuit 18 as memory write data via the signal line 9.

Although FIG. 1 shows that N pieces of switching information are stored in the storage circuit 18 in the order of identification addresses and addresses, it is possible to increase the identification address value within the range allowed by the storage capacity. By operating the operation panel 1, it is possible to increase the registration property p or change the switching information indicated by the existing identification address.

Next, manual switching performed by inputting only the switching information identification address from the operation panel 1 will be described.

When a switching operation is instructed by the operation panel 1, a switching operation instruction signal is output on the signal line δ, and an identification address signal set on the operation panel 1 to select the switching information registered in the memory circuit 1B is also output. It is output on Line 4. As a result, similarly to the above registration, the address stored in the address register 6 also provides a storage address when reading switching information from the storage circuit 18. The memory read data read out from the memory circuit 18 onto the signal 1111 is input to the AND gate 10. When the switching operation instruction signal on the signal line 6 is output, the AND
Storage read data can be output to the output side of the gate 10. This data is stored in the data register 16 via the signal line 12 as switching information read data.

When the switching information stored in the storage circuit 18 is stored in the data register 16, a switching operation instruction signal sent from the operation panel 1 via the signal line 6 is input to the switching control circuit 15. Therefore, the above data is sent out as switching information on the signal line 14, thereby enabling the switching control circuit 15 to manually switch the switching device.

(Effects of the Invention) The present invention is as follows. As explained above, switching is performed by storing switching information specifically indicating the switching state data of the switching device in a storage circuit, and by controlling the switching so that it can be switched any number of times as long as the above data is stored. Since there is no need to manually input switching information from the operation panel each time, there is an effect that the operability of manual switching of the system monitoring device is improved.
