Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to an electronic exchange, and particularly to a high-speed command execution method that allows a large number of commands to be executed at high speed.

(b) Background of the Technology Humans can give various commands to electronic exchanges by inputting commands from an input/output device such as a typewriter. The electronic exchange outputs the execution result of the input command to an input/output device, such as a typewriter device, as a normal completion message or an abnormal completion message. Note that protection measures are provided so that important commands such as changing the operating conditions of the electronic exchange cannot be executed unless a guard release command is input and executed in advance.

(c) Prior Art and Problems FIG. 1 is a diagram showing an example of a conventional electronic exchange, and FIG. 2 is a diagram showing an example of a conventional command execution method in FIG. In FIG. 1, a typewriter device TYP is provided as an input/output device for inputting commands and outputting messages. In FIGS. 1 and 2, for example, when a maintenance person inputs a command from the typewriter device TYP, the central control device CC receives the input command via the typewriter control device TYC, and the input command is It is determined whether or not the guard release command needs to be executed (step S1). If the command does not require execution of the guard release command, the command is executed immediately (step S4). If the input command requires the execution of a guard release command, it is determined whether the guard release command has already been executed (step S2), and if it has not been executed, the command is sent via the typewriter control device TYC. The typewriter device TYP is caused to output an abnormal termination message (step S3), and if the guard release command has already been executed, the command is executed (step S4).
The central controller CC determines whether or not the input command has been executed normally (step S5), and if the input command has been executed normally, the central controller CC executes the typewriter device TYP via the typewriter controller TYC.
output a normal completion message (step S).
6), and if the process ends abnormally, an abnormal end message is output (step 7). After confirming the normal termination or abnormal termination message output from the typewriter device TYP, the maintenance person starts inputting the next command if necessary. FIG. 3 is a diagram showing an example of the process of inputting and executing a large number of commands in succession in FIG. 1. In FIG. 3, after command A is input and executed, the next command B is input after a normal completion message is output, and commands M and N that require a guard release command to be preceded are as follows: A guard release command is input in advance, and the command is input after waiting for a normal completion message to be output as a result of execution.

As is clear from the above explanation, in the conventional command execution method, the central control unit CC always outputs a normal completion or abnormal completion message every time it executes an input command, and the maintenance person is responsible for outputting the message. I had to wait for it to finish before entering the next command. In addition, important commands such as changing the operating conditions of electronic exchanges are
It was necessary to input and execute the guard release command in advance. Therefore, when a large number of commands had to be input and executed at once, such as when an electronic exchange was first installed, there was a drawback that a large amount of time was required.

(d) Purpose of the Invention The purpose of the present invention is to eliminate the drawbacks of the conventional command execution methods as described above, and to realize a means that can reduce the time required to input and execute a large number of commands as much as possible. Ru.

(e) Structure of the Invention The purpose of this invention is to provide an electronic exchange equipped with a command input/output device with means for switching between a general operation mode and a high-speed operation mode, and to A message indicating normal termination or abnormal termination is output after the command is executed, and a predetermined command can be executed after executing a guard release command in advance, and when the switching means is set to high-speed operation mode, the command This is achieved by stopping the output of a message indicating normal termination when the command terminates normally, and by making it possible to execute the predetermined command without executing the guard release command.

That is, in the present invention, when the switching means is set to the high-speed operation mode, the output of the normal completion message is omitted when the command execution result is normal completion, and the guard is also set when executing important commands. Since there is no need to precede the release command, the time required to execute the command is shortened.

(f) Embodiment of the invention An embodiment of the invention will be described below with reference to the drawings. FIG. 4 is a diagram showing an electronic exchange according to an embodiment of the present invention, FIG. 5 is a diagram showing a high-speed command execution method according to an embodiment of the present invention, and FIG.
The figure is a diagram showing an example of the process of inputting and executing the same amount of commands in succession in FIG. 4. Note that the same reference numerals indicate the same objects throughout the figures. In FIG. 4, a changeover switch SW is provided for switching the operating mode of the electronic exchange, and is connected to a central control unit CC' via a scanning device SCN. The central control unit CC′ has a changeover switch SW,
Whether the mode is set to general operation mode or high-speed operation mode is monitored via the scanning device SCN. In FIG. 5, for example, when a maintenance person inputs a command from the typewriter device TYP,
When the central control unit CC' receives a command input via the typewriter control unit TYC, it first identifies whether the changeover switch SW is set to the general operation mode or the high-speed operation mode (step S11), If the general operation mode is set, the necessity of the guard release command (steps S12 and S1) is determined in the same process as in Figure 2.
After confirming 3), the input command is executed (step S15). On the other hand, if the changeover switch SW is set to the high-speed operation mode, the central controller CC' immediately executes the input command without constantly checking whether the guard release command is necessary (step S15). The central control unit CC identifies whether or not the result of executing the input command has ended normally (step S16), and if it has ended normally, it further identifies the setting state of the changeover switch SW (step S17). If the normal operation mode is set, the typewriter TYP is caused to issue a normal completion message via the typewriter control device TYC as in FIG. 2 (step S18), but if the high-speed operation mode is set. If so, omit the output of the normal completion message. In addition, in case of abnormal termination, changeover switch SW
An abnormal end message is output regardless of the setting state (step S19). The maintenance person confirms that no abnormal termination message is output from the typewriter device TYP, and starts inputting the next command if necessary. In Figure 6, if an abnormal end message is not output after command A is input and executed, input of the next command B is immediately started, and command M that requires a guard release command to be preceded.
And command N also starts inputting immediately without inputting the guard release command in advance.

As is clear from the above explanation, according to this embodiment, if the input command is successfully completed, the central controller CC' can immediately input and execute the next command without outputting a normal completion message. becomes. Also, important commands such as changing the operating conditions of the electronic exchange can be input and executed immediately without waiting for the input of the guard release command.
Therefore, the time required to input and execute commands is significantly reduced. In particular, when a large number of commands must be input and executed at once, such as when the electronic exchange is first installed, the amount of time required can be saved significantly.

Note that FIGS. 3 to 6 are only one embodiment of the present invention, and for example, command input and output are not limited to the typewriter device TYP, and many other modifications may be considered. However,
In either case, the effects of the present invention remain the same. Further, the command processing process is not limited to that shown in FIG. 6, and many other modifications may be considered, but the effects of the present invention will not change in any case. It goes without saying that the configuration of the electronic exchange to which the present invention is applied is not limited to that shown in the drawings.

(g) Effects of the Invention As described above, according to the present invention, the time required to input and execute a large number of commands in the electronic exchange can be significantly reduced, and the required man-hours can also be significantly reduced.
