Abstract

PURPOSE:To omit the reinput of a command to a minor command input mistake by preparing a confirming type for the result of analysis in addition to the normal and abnormal types and converting a wrong command name and a wrong key word caused in a command input operation into the most approximate formal command name and key code to confirm them. CONSTITUTION:An analyzing means 11 outputs the results of analyses in three types, i.e., the normal, abnormal, and confirming types. An analyzing result deciding means 12 decides the result of analysis. When the result of analysis is identical with a confirming type, a confirming information setting means 15 sets the confirming information and confirms whether the command name and the key word substituted in a system are correct or not by a terminal equipment 1 via a controller 2. Then this confirming result is judged by a confirming result judging means 16 via X controller 2. If the satisfactory result is judged by the means 16, an analyzing result setting means 13 sets the result of analysis. If the command name and the key word substituted in the system are not satisfactory, and error information setting means 14 sets the error information. Then the error information is displayed at a terminal equipment 1 via the controller 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a command analysis method, and more particularly to a command analysis method in a system in which an operator inputs a command from a terminal device and executes the command.

[0002]

2. Description of the Related Art FIG. 10 is a block diagram showing an example of a conventional command analysis method. As shown in FIG. 10, 21 is a terminal device, 22 is a control device, 23 is an execution device, 24 is an analysis device, 31 is an analysis means, 32 is an analysis result determination means, 3
Reference numeral 3 is an analysis result setting means, and 34 is an error information setting means. As shown in FIG. 10, the analysis device 24 receives the command input from the terminal device 21 via the control device 22.
The received command is analyzed by the analysis means 31 of the analysis device 24.

FIG. 11 is a flow chart showing an example of the operation of the analyzing means 31 shown in FIG. The command analysis method will be described with reference to FIG. The command name is extracted from the received command, the command name table is searched (301), it is determined whether or not it is found in the command name table (302), and if not found, an error information output request is made (309). , The process ends. If found, it is judged whether or not the command is completed (303), and if completed, a command execution request is made (308), and the process is ended.

On the other hand, if not completed, the keyword is extracted from the received command, the keyword table is searched (304), and it is judged whether or not it is found in the keyword table (305). If not found, an error is detected. An information output request is made (309), and the process ends. If found in the keyword table, the parameter value is extracted from the received command, the parameter value is checked (306), and it is determined whether the parameter value is normal (307).
A request is made to output error information (309), and the process is terminated. If the parameter value is normal, it is determined whether the command is completed (303) and the following processes are repeated.

Therefore, two types of results, normal and abnormal, are returned as the analysis result by the analysis means 31, and the analysis result determination means 32 determines the analysis result. If the analysis result is normal, the analysis result setting means 33 analyzes the result. The result is set, passed to the execution device 23 via the control device 22, the command is executed, and the execution result is displayed on the terminal device 21 via the control device 22. If the analysis result is abnormal, the error information setting means 34 sets the error information, and the terminal device 21 is set via the control device 22.
Error message is displayed.

As described above, in the conventional command analysis method, there are only two types, that is, the analysis result is normal or abnormal. Even if the command input error is a trivial input error, I had to enter the command again.

[0007]

In the conventional command analysis method described above, when the command input by the operator via the terminal device is incorrect, an error message indicating the reason for the error is displayed on the terminal device. Therefore, the command has to be re-entered again in order to execute the command, which is a burden on the operator.

[0008]

According to the command analysis method of the present invention, an analysis device which receives a command input from a terminal device via a control device performs a grammatical check of the command, and the analysis result is controlled by the control device. If the analysis result is normal, the control device instructs the execution device to execute a command, receives the execution result and displays it on the terminal device, and if the analysis result is abnormal, an error message is sent to the terminal device. In the command analysis method shown in FIG. 5, when the analysis device analyzes the command, the analysis result determination device determines the analysis result received from the analysis device, and the analysis result determination device determines that the analysis result is normal. Analysis result setting means for setting the analysis result, and an error information setting means for setting error information when the analysis result judging means judges that there is an abnormality. A confirmation information setting means for setting confirmation information when the analysis result determination means determines that the confirmation information is set, and the confirmation information set by the confirmation information setting means is displayed on the terminal device via the control device. It is configured to include a confirmation result determination unit that receives a confirmation result from the terminal device via the control device and determines a confirmation result.
