FIG. 3 is an explanatory diagram for explaining a function in a case where an electronic mail is issued by applying the sequencer 2, the frame converter 3 and the modem 4 from the facility 1 to the monitoring center 6 described above. is there.

As shown in FIG. 3, the equipment 1 and the sequencer 2 are connected via an input / output port 17. Then, for example, abnormality information and other operation information can be input to the sequencer 2 as digital inputs from a relay 18 of the equipment 1, a contact 18 including a push button and other various switches. Analog inputs of voltage, current, fluid flow rate, and other various variable elements are input to the sequencer 2 via the transducer 19.

The sequencer 2 incorporates a control sequence program corresponding to the equipment 1 and has a predetermined program control function including a sequence operation circuit and an arithmetic operation circuit. Further, the sequencer 2 has a function of creating operation information corresponding to the set monitoring item as monitor information, and stores the created monitor information in a predetermined data area. When abnormal information is input, a predetermined flag is set up and stored in the register 20 as a data area, and a report request is issued. Note that a data input device such as a personal computer can be connected to the sequencer 2, and abnormality monitoring of the equipment 1 can be continuously performed by inputting control data such as monitoring items and conditions.

On the other hand, a frame converter 3 is connected to another input / output port (not shown) of the sequencer 2.
The frame converter 3 has a frame conversion function between a control frame of the sequencer 2 and a communication frame of the modem 4, has a control function according to a predetermined transmission / reception program by a CPU, and has the alarm information from the sequencer 2. Has an alerting message database for storing messages corresponding to. As shown in FIG. 3, the alarm message database includes, as a flag table 21, a "flag position", a "mail body" corresponding thereto, and a "report destination" which is a telephone number of the monitoring center (ASP center) 6. Information such as "telephone number" is recorded.

Then, the flag is always read out by the frame converter 3 (S1). If there is a change in the flag (S2: YES), the mail text corresponding to the changed flag is read from the flag comparison table 21. Then, the report destination telephone number is extracted (S3), and a mail having the content of the mail is outputted (S4).

This e-mail is transmitted via the modem 4 as e-mail using the direct transmission method between slave units of the public telephone network to the monitoring center 6 which is the telephone number of the report destination. In the case of e-mail using this direct transmission method between slave units, e-mail information issued from the modem 4 is directly transmitted to the communication means on the management center 6 side, and arrives instantly (for example, in about three seconds). Therefore, abnormal information is received at a very high speed.

Therefore, a large number of facilities 1 owned by a large number of users can be rationally monitored by one or a small number of monitoring centers 6, and desired information can be provided to each user promptly and inexpensively in a timely manner. It can be effectively applied as a service.

Also, the types and scales of the facilities 1 owned by each user are different, installation locations are scattered in various places,

And it can be widely used.

FIG. 4 shows a processing flow of mail storage processing in the monitoring center 6 which has received the above-mentioned electronic mail.

As shown in FIG. 4, FIG. 1 and FIG. 2, when the electronic mail is received by the communication means of the monitoring center 6, the server of the monitoring center 6 first executes " The "acceptance time" is temporarily recorded in the temporary storage area as the mail history table 22 (S101), and the mail content is divided into a telephone number (terminal device ID) as a calling modem and a mail text (flag position). Temporarily recorded (S10
2).

Next, registration confirmation of the terminal device ID which is the mail originating modem 4 is performed with the user authentication database 23 of the database server 11 (S103). If there is no registration (S103: NO), Email storage is rejected. In other words, regarding a mail that is erroneously sent from equipment other than the user equipment to be monitored by the monitoring center 6, mail storage rejection processing is performed by confirming the registration of the terminal device ID, thereby increasing the reliability of reception. As well as ensuring security management.

On the other hand, in this step (S103), if it is confirmed that the calling modem 4 is a legitimately registered terminal device (S103: YES), the facility 1 owned by a predetermined user starts. , And the flag is interpreted (S104).

In the flag interpreting step (S104), a comparison is made with the text conversion table 24 stored in the database server 11 so that the transmission source terminal device ID shown in the correspondence relation with this table is compared with the text conversion table 24. , The contents of the report are retrieved, and the contents of the report are extracted. The report content extracted from the text conversion table 24 matches the report content of the mail history table 22 that was collated when storing the reception time record, telephone number, and text.

When the reception time, the terminal ID of the transmission source device, the contents of the report, and the like are specified by the above processing, the mail is recorded in the mail history database 25, that is, the mail is stored (S105). The mail history is accumulated for each facility and each time.

Although the description is omitted in this embodiment,
In the monitoring center 6, for the abnormality of the equipment specified based on the received information content, a report to the user, an instruction of a coping method, a mail reply to the transmission source equipment, and the like are separately performed. By these processes, measures such as abnormal recovery of equipment, operation stoppage, operation of compatible equipment, and the like are performed, and the results of these measures can be included in the mail history.

After the mail history is stored, the equipment 1
A mail conversion process is performed to convert the mail form from the side into a mail form (E-mail) via the Internet corresponding to the predetermined user terminal 16 (S10).
6).

In this mail conversion process, conversion to necessary preset message contents is performed based on, for example, the terminal device ID of the user. That is, in this step, first, a search is performed for a user ID registered in the e-mail address registration table 26 of the database server 11 or a group ID registered as a contact to which the user belongs. Then, the mail address is extracted from the table (S107).

Then, a list corresponding to the service is created according to the ASP program, and an e-mail is created based on the mail address (S108). And this e-mail is a mail server (e-mail server)
12 is stored. As a result, it becomes possible to respond to a service request such as the mail history request “2” from the user terminal 16.

Here, a procedure for a user to receive a service will be schematically described.

First, when the user first obtains the service permission by the monitoring center 6 individually or as a group, the user logs in from the web browser of the user terminal 16 and registers in the user authentication database of the monitoring center 6 based on the web server program. receive.

The monitoring center 6 returns a response of an available service menu to the user terminal 16 logged in to the web server. Thus, the user can select a service corresponding to the service menu that has received the response, and make a service request to the web server of the monitoring center 16.

When there is a service request from the user, the monitoring center 6 starts the service after confirming the user ID or group ID registered in the user authentication database by the web server program.

The center server of the monitoring center 6 has a program for registration / change to each database, and registration / change to each database can be performed at any time in response to a registration / change request from a user. I have. When making this addition / change, the user logs in from the web browser of the user terminal 16 and receives registration based on the web server program in the user authentication database of the monitoring center 6.

FIG. 5 shows a flow of a specific processing procedure in the monitoring center 6 when the above-mentioned mail history request “2” is issued.

As shown in FIGS. 5, 1 and 2, the monitoring center 6 is transmitted from the user terminal 16 via the Internet.
When a mail history request is made to the monitoring center 6, the monitoring center 6
First, based on the P program, user authentication is performed by collation with the user authentication database 23 (S20).
