An object of the present invention is to provide an information processing method in a telecontrol system that shortens the data collection time described above.

Means for Solving the Problems> In order to achieve the above object, an information processing method in a telecontrol system of the present invention includes extracting a plurality of inquiry signals for the same slave station from the plurality of inquiry signals at the supervisory control station. In response to a request from the supervisory control station, a predetermined slave station returns information about the status of multiple loads connected to itself at once, and the supervisory control station transmits the information to the slave station. This is an information processing method for extracting predetermined data from a set of information regarding the status of a plurality of loads returned from.

Effect> With the information processing method in the telecontrol system as described above, when inquiring about the control status of multiple devices connected to multiple slave stations at the supervisory control station,
First, words for the same slave station are extracted from multiple inquiry signals, and multiple words of information regarding the status of multiple loads connected to the same slave station are collectively requested. In response to an inquiry from a control station, multiple words of information regarding the status of multiple loads connected to the station are returned at once, so the supervisory control station can extract a predetermined number from the set of words returned from the slave station. Data can be extracted, and processing such as data collection and display can be performed quickly.

<Example> Hereinafter, embodiments will be described in detail with reference to the accompanying drawings showing examples.

The outline of the telecontrol is as already shown in FIG. 5, and the same reference numerals are used.

FIG. 2 is a functional block diagram for implementing the information processing method in the telecontrol system of the present invention, showing only the relationship between the supervisory control station (1) and one slave station (5).

The supervisory control station (1) displays the status of the load (7) and uses a CRT to specify multiple loads (q) to be queried.
A desk (11) and the above CRT by processing multiple input data.
An information processing device (1) that generates a transmission signal (see FIG. 4A) that is supplied to the console (11) and also inquires about the status of a plurality of loads (7) specified in the CRT console (11).
2), the signal transmitted from the dataway ■ is supplied to the information processing device (12), and the inquiry signal from the information processing device (12) is sent to the dataway ■
and an information transmission device (13) for transmitting information to.

On the other hand, the slave station (5) communicates with the supervisory control station (
In response to an inquiry from 1), the status of load ■ is transmitted. A digital scanner (52) scans the state, and the ON state is determined based on the output pulse from the scanner (52).
lJ, the OFF state is binarized as "0", and a predetermined number of binarized pulses are put together into one word (Fig. 4B
a word generation circuit (53) that converts parallel information compiled in word units into a serial signal to generate a teleconverter input signal, and a parallel/serial conversion circuit (54) that generates a teleconverter input signal and modulates the serially converted data. In addition, the MOD (55) is transmitted to the supervisory control station (1) at predetermined time intervals.

FIG. 3 is a diagram illustrating the position information relationship for the information processing device (12) to process the teleconference input data. Since the slave station (5) only transmits the status of the load (7) with one bit consisting of "0" and "1", for example, 16
To transmit the status of each load (7), 16-bit signals are enumerated. As it is, it is not possible to know which load (7) is in the state, so using the position information relationship diagram, it is possible to determine which load (7) it is based on the bit position.

The word processing operation of the above telecontrol system will be explained. The information processing device (12) of the supervisory control station (1) processes the teleconverter input signal transmitted from the slave station (5) at predetermined time intervals based on the position information related diagram, and based on this processed signal. The status of the load (7) is displayed on the CRT console (11).

Then, by operating the CRT console (11), multiple loads (7
) is specified, the information processing device (12) extracts the load (7) connected to the same slave station (5) from the multiple loads (7) specified based on the position information relationship diagram. Then, as shown in FIG. 4A, a request word consisting of the address of the transmission relay device (3), the address of the slave station (5), a request code, and a load code is generated, and a plurality of these words are put together and sent to the information transmission device. (13) and sends it to the data way ■.

The slave station (5) replies with the number of words corresponding to the plurality of words in the inquiry. That is, as shown in FIG. 4B, multiple loads (including the address of the transmission relay device, the address of the slave station (5), the reply code, and the inquiry load)
7) A plurality of reply words consisting of the status data are transmitted together.

The information processing device (12) of the supervisory control station (1) can separate and extract the data of the queried load (7') from the reply word based on the position information relationship diagram.

FIG. 1 is a flowchart showing the information processing method of the present invention.

In step (2), the state of the load (7) is displayed by the CRT console (11) based on the teleconverter input signal transmitted from the slave station (5) at predetermined time intervals.

In step (2), the CRT console (11) is operated to specify a plurality of loads.

In step (2), loads (7) connected to the same slave station (5) are extracted from the specified plurality of loads (7). That is, the same words are extracted.

In step (2), a plurality of request words are sent together from the information transmission device (13) to the dataway (2).

In step ■, it is determined whether or not the requested number of words has been transmitted, and if it is determined that the requested number of words has not been transmitted,
Perform the process in step (■). Further, if it is determined that the requested number of words has been transmitted, the processing from step (2) onwards is performed.

In step (2), the slave station (5) receives the request word and returns a plurality of reply words including status data of a plurality of loads (7) including the inquiry load (7).

In step (2), the information processing device (12) of the supervisory control station (1) processes (separates and extracts) the data of the load (7) inquired from the reply word.

In step (2), it is determined whether or not the processing has been performed a number of times corresponding to the requested number of words. If it is determined that the processing has not been performed a number of times corresponding to the requested number of words, the processing in step (2) is performed. If it is determined that the requested word has been processed several times, the process moves to the display routine of step (2).

As shown in the above flowchart, the control and monitoring station (1) extracts the same words and sends them all to the slave station (5), and the slave station (5) replies to the inquiry with multiple words at once. Therefore, the control and monitoring station (1) can separate and extract predetermined data from the group of reply words, and can shorten the data collection time.

Effect> As described above, according to the information processing method in the telecontrol system of the present invention, words for the same slave station are extracted from a plurality of inquiry signals at the supervisory control station, and words for the same slave station are extracted from multiple inquiry signals. The slave station requests multiple words of information regarding the status of multiple loads at once, and the slave station requests multiple words of information regarding the status of multiple loads at once in response to the zero adjustment from the supervisory control station. Since the message is sent back, the supervisory control station can extract the specified data from the group of words sent back from the slave station.
This has the unique effect of shortening data collection time.
