Abstract

PURPOSE:To attain the identification by an ear of a commander by connecting a simultaneous command board finally to a common tone source and disconnecting it finally. CONSTITUTION:In connecting a tone source to inform the start of a command to the simultaneous command reception terminal equipment with the simultaneous command reception terminal equipment, the source is connected finally to the command board. The commander confirms it by listening to the tone by its own ear that the simultaneous command reception terminals of the simultaneous command object are in the state of simultaneous command start notice. At the start of simultaneous command transmission, the command board and the speech path of the tone source are released finally. The commander confirms it from the unheard tone to its own ear as to the discrimination when talking is to be started. Thus, the command operation is simplified more and the display lamp corresponding to the simultaneous command reception terminal equipment is not required.

Description

[Detailed Description of the Invention] [Summary] In a simultaneous command control method for command receiving terminals, -
By finally connecting the command console to the common tone sound source and disconnecting it last, the command center can be identified by the ears of the dispatcher.

[Industrial application field]

The present invention relates to a simultaneous command control device, and more particularly to a simultaneous command control system in which a commander arbitrarily selects a plurality of simultaneous command receiving terminals from among a plurality of simultaneous command receiving terminals and issues a simultaneous command.

In recent years, F[i-order control equipment has been enriched with functions as an information processing system, and is often operated in synchronization with a computer, making it necessary to install a computer display terminal on the command desk. It's been a long time since I've been in the middle of a long time. This shows that the amount of information that the dispatcher must read visually when giving a command is increasing dramatically.
In other words, it shows that the burden placed on the commander's eyes is becoming heavier. Therefore, reducing the number of visual check items has become an important issue in order to reduce the burden on the dispatcher.

[Prior art]

In the conventional one-house command control system (・), an indicator lamp is provided on the command base surface corresponding to a plurality of simultaneous command receiving terminals, and the status of the simultaneous command receiving terminals is displayed using the lamp. The lamps of terminals receiving simultaneous commands that are notifying are made to flash, and the lamps of terminals receiving simultaneous commands that have become capable of transmitting simultaneous commands are to be lit. By doing so, it is a trap to judge the current state of all the simultaneous command receiving terminals that are subject to the simultaneous command and to perform the next operation.

[Problems to be solved by the invention]

However, in the conventional simultaneous command control system, as the number of receiving terminals targeted for simultaneous commands increases, the number of display lamps increases correspondingly, and when the commanding person wants to perform the next operation, he or she always has to use his/her own eyes. Since a large number of display lamps have to be checked at the same time, the operability is poor, and the command desk has to be thick (and cluttered).

[Means and effects for solving the problems] In order to eliminate the above-mentioned drawbacks, the present invention provides: - a tone sound source for notifying the start of a command to a simultaneous command receiving terminal; When connecting to the command receiving terminal, by also connecting to the command console at the end, the dispatcher can hear a tone in his/her ears that all the command receiving terminals that are subject to the simultaneous command are in the state of notifying the start of the simultaneous command. Similarly, when starting to send commands all at once, the communication path between the command desk and the tone sound source is released at the end, so that the dispatcher can hear the tone and know when to start speaking. Confirmation is made by not being able to hear the command, making the command operation easier, and since there is no need for an indicator lamp that is not compatible with the -★ command receiving end, it is possible to make the structure of the command desk more mainstream.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

1 and 2 show embodiments of the present invention, ■ in the figures represents a communication path network of a digital electronic exchange, solid lines in the communication path network represent connection of communication paths, and similarly, dotted lines represent communication paths. ■ represents the command console, ■ represents the receiving terminal for simultaneous commands, ■ represents the common tone sound source for notifying the start of command transmission, and ■ represents the central control unit that controls all of these. Now, if a command is to be issued all at once from the command console in FIG. 1, the commander first selects a command target from the command console (2) and notifies the central control unit (2) of the selection. Based on the notification, the central controller ■ activates the simultaneous command receiving terminal ■ and waits for a response signal from the receiving terminal ■, and at the same time captures a common tone sound source ■ to notify the start of command transmission. , and the receiving terminal (■) that received a response is sequentially connected via the communication path network (■). When response signals are returned from all the receiving terminals ■ (after connecting the tone sound source ■ to all the receiving terminals to be commanded), finally connect the receiving terminal A of the command console ■ to the tone sound source ■ and send the message to the dispatcher. Notify that the command is ready. In other words, the dispatcher checks the display lamp that corresponds to the simultaneous command receiving terminal.
It is possible to judge by listening to the tone from the tone source ■.

In this state, if the dispatcher makes a command transmission request as the next operation, the state changes to the state shown in Figure 2, and the command console connects the transmitting terminal B of the command console ■ to all the receiving terminals ■ subject to simultaneous commands. ■
At this time, the sending terminal B of the command center ■ and the simultaneous command receiving terminal ■ are first connected, and then the communication path from the tone sound source ■ to the receiving terminal of the command center ■ is established. Do the release last. By controlling the connection in this way, the dispatcher can immediately start speaking from the moment the tone is no longer heard. (This is because the connection between the command console ■ and the simultaneous command receiving terminal ■ has already been completed when l/- releases the communication path between the sound source ■ and the command console ■.)
Therefore, at this time as well, there is no need to check the display lamp as in the case of notifying the start of command transmission.

[Effects of the Invention] As described above, according to the present invention, items that were conventionally checked with the eyes can be distributed to the ears without the need for new equipment, further reducing the burden on the dispatcher. This allows for excellent operability, higher reliability of command information, and a simpler structure for the current command console.
