Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a standardized operation management device that can cope with changes in specifications such as starting, stopping, and changing operating modes of computers in a multiplexed computer system consisting of a plurality of computers. It is related to.

FIG. 1 is a block diagram showing an operation management device in a conventional multiple computer system, and shows, as an example, a case where a dual system is configured.

In the figure, la and lb are computers, 2 is an operation management device that controls the role and operation mode of each computer la and lb, and 3a and 3b are computers l.
4 is an operator panel; 5a and 5b are hardware circuits 6a and 6b that determine the operation mode according to a certain specification based on instructions from the computers la and lb or manual instructions from the operator panel 4, respectively; is an operation management information register that holds this operation mode. Next, the operation of the operation management device in the multiple computer system according to the above configuration will be explained.

First, the computer la accesses its own operation management information register 6a via the interface circuit 3a and hardware circuit 5a of the operation management device 1. As a result, the operating state information is read from the operating management information register 6a and input to the computers la and lb. Simultaneously with this operation, it is also possible to access the system operation management information register 6b via the interface circuit 3b and the hardware circuit 5b. As a result, the operating status information is read from the operating management information register 6b and the computers la and l
Enter b. However, in conventional operation management devices for multiple computer systems, interface circuits, hardware circuits, and operation management information registers are composed of individual hardware circuits such as relays and ICs, and complex logic and interlock circuits are required for each system. designed,
Because it is manufactured, it is difficult to standardize it, and it is also difficult to modify the hardware in response to changes in specifications.

Furthermore, when using relays, the operating speed is slower than that of semiconductors, and there are drawbacks such as the need to use mechanical holding relays in order to maintain operation management information even after power is lost. Therefore, an object of the present invention is to provide an operation management device that can flexibly deal with the specifications of each system, is easy to standardize, and is highly reliable.

In order to achieve such an object, the present invention has a plurality of input/output boats provided corresponding to each computer, and an operation mode based on an instruction from each computer or a manual instruction from an operator panel. It is equipped with a program Liu's logic decision circuit using a microprocessor that determines the role of the computer, and a register consisting of a semiconductor memory that is provided corresponding to each computer and maintains the latest operating status. This will be explained in detail using examples.

FIG. 2 is a block diagram showing an embodiment of the operation management device in a multiple computer system according to the present invention, and shows, as an example, a case where a dual system is configured.

In the figure, 7a and 7b are computers la and lb.
8 is a logical decision circuit 9a using a microprocessor that determines the operation mode based on instructions from the computers la, lb or manual instructions from the operator panel 4. Reference numeral 9b is a register made of semiconductor memory that holds the latest operating state. Next, the operation of the operation management device in the multiple computer system according to the above configuration will be explained. First, the computer la inputs and outputs information to and from the logic judgment circuit 8 via the standardized board 7a. In this case, since the logic judgment circuit 8 uses a microprocessor, this microprocessor sets the registers 9a and 9b according to preprogrammed judgment criteria based on manual instructions from the computers la, lb and the operator panel 4. do. Therefore, the latest operating state information is always held in the registers 9a and gb. In this case, the microprocessor sorts out conflicts between computers la and lb and manual instructions from outside, masks and unmasks 10 ports under certain conditions, and performs interoperability between computers la and lb under certain conditions. Various conditions can be given in advance by a program. Although the above description has been made regarding the case of an operation management device for a dual-system system, the present invention is not limited to this, and it goes without saying that the present invention may be used for a single-system normal operator's console, a general-purpose terminal control device, and the like.

As explained in detail above, according to the operation management device for a multiple computer system according to the present invention, ■ By standardizing the hardware and changing the program,
Able to handle required specifications and specification changes for each system.

{B' By adding a battery, the status information before power loss can be easily protected and the continuity of operation management information can be guaranteed even after power is restored. } Simplify the interface with the computer,
It can be standardized, and access from computers to operation management equipment can also be standardized. ■ Q&A between a computer and a microprocessor is possible at the same level as compared to between a computer and a relay circuit, and has the advantage of being faster and simpler.
