4 and run the command. The execution result of the command is sent back to the startup computer 3 by the execution side communication means 41. This execution result is expressed in the execution result expression format of the execution computer 4. The execution result received by the activation side communication means 33 is translated by the execution result translation means 35 into the execution result expression format of the activation computer 3 and displayed on the display means 2.

[Problems to be Solved by the Invention] This conventional translated remote command execution system uses a command translation means and an execution result translation means on the startup computer to translate commands and execution results between the startup computer and the execution computer. Therefore, when adding computers with different command language formats and execution result expression formats as startup computers and execution computers, it is necessary to prepare command translation means and execution result translation means for the number of combinations of computers. The drawback was that it was difficult to configure.

An object of the present invention is to provide a remote command execution system that can easily construct a system between many different types of computers by limiting the number of command translation means and execution result translation means, by eliminating the above-mentioned drawbacks. The goal is to provide a system.

[0006]

[Means for Solving the Problems] The present invention provides an activation computer including a communication means for transmitting commands and execution results, and an execution computer connected to the activation computer via a network and including the communication means and a command execution section. In the remote command execution system, the communication means is configured to transmit commands and execution results in a certain intermediate command format different from the internal format of the computer, and the startup computer and the execution computer are each a computer. The present invention is characterized in that it includes a command translation means for translating between an internal command format and the intermediate command format, and an execution result translation means for translating between the execution result format inside the computer and the intermediate execution result format.

[0007]

[Operation] The communication means transmits data in a certain intermediate command format different from the commands inside the computer. In the startup and execution computers, the command translation means and the execution result translation means respectively translate the transmitted intermediate command format and the command format within the computer.

Therefore, when constructing a remote command execution system between many different types of computers, it is sufficient to provide command translation means and execution result translation means for each computer model, making it easy to construct the system. It becomes possible.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a first embodiment of the present invention. The first embodiment includes an activation computer 3 including an activation side communication means 33a for transmitting commands and execution results, an execution side communication means 41a connected to this activation computer 3 via a network 5, and a command execution section 44. In a remote command execution system comprising an execution computer 4 including:

A feature of the present invention is that the activation side communication means 33a and the execution side communication means 41a are configured to transmit commands and execution results in a fixed intermediate command format different from the internal format of the computer. The computer 3 and the execution computer 4 each have an invoking side command translation means 31 and an execution side command translation means 42 that translate between the command format inside the computer and the intermediate command format, and the execution result format and intermediate execution result inside the computer. Invoking-side execution result translation means 32 and execution-side execution result translation means 43 that perform translation between formats.
Contains.

Next, the operation of the first embodiment will be explained with reference to the flowchart shown in FIG. First, the user inputs an execution command into the input means 1 in the command format of the starting computer (step S1). The command is translated into an intermediate format by the initiating side command translation means 31 (step S2), and is transmitted to the execution host computer 4 by the invoking side communication means 33a (step S3). In the execution computer 4, the execution side communication means 41a receives the command in the intermediate format, and the execution side command translation means 42 translates it into a command in the format of the execution computer 4 (step S5), and starts the command execution unit 44 (step S6). . The execution result of the command execution unit 44 is translated into intermediate format execution result data by the execution-side execution result translation means 43 (step S7), and is sent back to the startup computer 3 by the execution-side communication means 41a (step S8).
. The intermediate format execution result returned to the starting computer 3 is received by the starting side communication means 33a (step S9).
) is translated into the execution result display format of the startup computer 3 by the startup side execution result translation means 32 (step S10).
, displayed by the display means 2 (step S11)
.

Through the above process, the command in the command format of the startup computer 3 input to the startup computer 3 is remotely executed by the execution computer 4, and the execution result is displayed from the startup computer 3 in the display format of the startup computer 3. . Since the execution computer 4a having other command formats and execution result display formats communicates with intermediate format commands over the network, remote command execution can be performed in the same way.

FIG. 3 is a block diagram showing a second embodiment of the present invention. The second embodiment includes an input means 1, a display means 2, a startup execution computer 6, and a network 5. The startup execution computer includes a startup side command translation means 31 and a startup execution result translation means 32.
, starting side communication means 33a , execution side communication means 41a ,
It includes an execution side command translation means 42, an execution side execution result translation means 43, and a command execution section 44.

In the second embodiment, the activation computer 3 and the execution computer 4 of the first embodiment shown in FIG. 1 are built into the same computer. Therefore, the startup execution computer 6 can play the role of either the startup side or the execution side of remote command execution.

Effects of the Invention As explained above, the present invention provides means for translating an intermediate command format and a command format of each computer in both the startup computer and the execution computer, and translation means for translating the intermediate format command format and the command format of each computer. By having a result format translation means and communicating in an intermediate format, even when building a remote command execution system between many different types of computers, you can prepare command translation means and execution result translation means for each computer model. This has the effect of making it easy to build a system.
