Next, the operation will be explained. FIG. 4 is an explanatory diagram of the operation of collecting customer data at a sales office in the wide-area system data collection method of FIG. 3, and its contents will be fully explained.

In FIG. 4, a data request 261 is transmitted from the automatic processing device 18 of the office to the customer 211, and
receives this data request and sends the reply 262 to the office, and the automatic processing device 18 receives this and stores it on the disk 19.

Next, when the automatic processing device 18 transmits a data request 271 to the consumer 212, it receives a reply 272 sent from the consumer 212 and stores it in the disk 19.

Similarly, the automatic processing device 18 performs the same process for uncollected customers, and the sales office collects customer data in series up to the last customer 23n and stores it on the disk 19.

The relay devices 201 to 2On have only a line concentration function such as the communication lines 171 to 17n.

[Problems to be Solved by the Invention] Since the conventional wide-area system data collection system is configured as described above, between the relay devices 201 to 20n and the customers 211 to 23n in FIG. Low-speed transmission is often implemented due to the cost of transmission equipment and communication lines, and in the conventional method, sales offices collect data from customers in series, resulting in a large number of data (several thousand to hundreds of thousands). When targeting consumers, there were problems such as the long time required to collect system-wide data.

In addition, as an approximation technique, Mitsubishi Electric Technical Report Vo161°No.
12, 1987, ``Information Communication and Power Distribution Automation'' on pages 34 to 37.

This invention has been made to solve the above-mentioned problems, and its object is to obtain a data collection method for a wide area system that can speed up the data collection time for the overall system at a business office.

[Means to solve all problems]

The wide-area system data collection method according to the present invention is equipped with a relay bag that collects customer data through parallel processing in sections where the data transmission speed between the relay device and the customer is slow and sends it back to the business office. It is.

[Effect]

The relay device in this invention is operated according to instructions from the business office.
Customer data is collected through parallel processing, and the collected data is sent back to the sales office via a relay device.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, 161 is a communication line that connects the automatic processing device 18 of the business office shown in FIG. Communication line or power line (power line transport system, etc.) connecting the data transmitting/receiving unit 15 and each consumer
It is.

This data transmitting/receiving section 15 transmits data to each consumer and transmits/receives data from each consumer in parallel.

14 is provided in the relay device 201, and the data transmitting/receiving section 13
．． Compiling data from 15 and data transmitting/receiving unit 1
3.15 is a data processing unit that instructs where to say data.

Although only the relay device 201 is shown in FIG. 1, the system configuration of the wide-area system data collection method of this invention is the same as that shown in FIG.
The symbols for communication lines 171 to 17n are the same as in FIG.

Furthermore, although the relay devices 202-2o3 degree communication lines 162-16n, 241-24n, and 251-25n shown in FIG. 3 are not shown in FIG. 1, they are similar to those in FIG. 3.

Next, the operation will be explained. FIG. 2 is an operational explanatory diagram for explaining the present invention in detail, and in the figure, 11.
51.91 is from the automatic processing device 18 of the office to the relay device 2
Data collection command for 01, 12,52.92 indicates return of collected data from the relay device 201 to the automatic processing device 1.8.O In order to speed up the data collection time of the overall system, the relay devices 201 to 20n Data collection from each customer is carried out completely in parallel. For example, it is impossible to simultaneously collect data from the customers 211 to 21n via the 11111 signal line 171r unless a method such as multiplexing is taken into consideration, since data returned from the customers to the relay device 201 will collide.

Therefore, data collection according to the present invention is a method of collecting data from each customer on a communication line.The relay device 201 is provided with a parallel processing function to collect data from multiple customers at the same time.

That is, as shown in FIG. 2, when the automatic processing device 18 of the office sends the data collection command 11 of the customer 211, 221, 231 to the relay device 201 as shown in FIG. 201, the data processing unit 14 instructs the data transmitting and receiving unit 15 to send data request commands 21. Call 1,41. These transmission times are approximately the same time.

Consumers 211, 221, and 231 each receive data request commands 21, 31, and 41 at approximately the same time, and then
Data 22, 32, and 42 are sent back to the relay device 201 from 1, 221, and 231, respectively. The relay device 201 receives these returned data 22, 32, 42 at the data transmitting/receiving unit 15, and then instructs the data transmitting/receiving unit 16 at the data processing unit 14 to process these returned data 22, 2.
3.Reply all 24 to the office.

Next, when the business office sends a data collection command 51 to the relay device 201, the data transmitter/receiver 16 of the relay device 201 receives it, and the data processor 14 instructs the data transmitter/receiver i15' to send it to the customer. 212.222.
The data request commands 61, 71, and 81Th are sent to the relay device 201, respectively, and the same procedures as described above are performed thereafter.
The data 52 is sent back to the sales office. Such operations are repeated up to the final customer groups 2in, 22n, and 23n.

By doing this, in the data collection time of 1 second/1 house, for 100,000 target examples, 100,000 seconds (approximately 28
If the parallel processing is set to 'IN=10, it will be possible to collect data in about 3 hours, which can speed up the collection time of the system's comprehensive data. Generally, the number of business offices is 100,000 to 500,000.

Up to this point, for ease of explanation, we have used three levels: sales offices, relay equipment, and customers. However, the four levels of sales offices, relay equipment, slave stations, and customers can also be applied to each hierarchy, and the number of floors is i. The same effect can be achieved even if there are many.

Furthermore, the term "business office" is given by a general name and includes business offices, branches, branch offices, control centers, and other locations having automatic processing equipment.

〔Effect of the invention〕

As described above, according to the present invention, a relay device that relays data transmission between a business office and a customer collects data from a customer through parallel processing according to a command from the business office, and sends the data to the business office. Since it is configured to send back data, it is possible to collect data from multiple consumers simultaneously using a relay device.
If the parallel processing is N, it has the effect of speeding up data collection for the entire system by about eight times.
