[0012]
Next, the operation will be described with reference to FIG.
When a failure or an alarm occurs in the plant equipment 1, the controller 2 receives the information and transmits the name of the equipment / equipment and the type of the failure to the database device 3. The database device 3 transmits information on the failure that has occurred to the Web server 5, and the Web server 5 receives the information (Step S1). The Web server 5 stores the information in the data storage unit 51 and sends a notification to the mail generation unit 52 at the same time. The mail generation unit 52 receives the latest alarm information from the data storage unit 51, and generates a mail including information such as the time of occurrence, the name of equipment / equipment, the type of failure, and the degree of importance (Step S2).
The generated mail is transmitted by the mail server unit 53 to the mobile monitoring device 6 of the notification destination registered in the notification destination information 54 (step S3). As means for notifying the mobile monitoring device 6, means using telephone voice may be used.
[0013]
The operator having received the notification (step T1) uses the mobile monitoring device 6 to make a connection request to the Web server 5 (step T2). Upon receiving the connection request from the mobile monitoring device 6 (step S4), the Web server 5 displays a list of alarm information that has occurred from the alarm information stored in the data storage unit 51 in Java (registered trademark), HTML, or the like. The screen is generated by the screen generation unit 55 in a format that can be viewed on a general-purpose browser, and transmitted from the Web server unit 56 as the first screen after connection to the mobile monitoring device 6 (step S5). The mobile monitoring device 6 receives the alarm screen (step T3), and displays a list of alarm information from the latest one as a list. Each item of the alarm information list has a link to a screen for detailed information such as a related trend graph and a device operation screen. The user selects the list and requests the screen (step T4). ). The Web server 5 receives the screen request (Step S6), and transmits the requested data to the mobile monitoring device 6 (Step S7). Based on this, the operator can confirm the detailed situation by using a trend graph or the like, and take necessary measures such as operating a spare device or making contact from anywhere (step T5).
[0014]
According to the first embodiment, since necessary detailed information can be directly referred to from the list of alarm information, monitoring can be easily performed even from a mobile monitoring device that is inoperable.
[0015]

In FIG. 6, when receiving the alarm information, the Web server 5 sets an ID number consisting of several digits for each alarm information (step S1-3). When transmitting the alarm information to the mobile monitoring device by e-mail or voice, the Web server 5 creates an e-mail including the ID number together with the failure information by the e-mail generation unit 52 (step S2-3). The mail is transmitted by the mail server unit 53 to the mobile monitoring device 6 of the notification destination registered in the notification destination information 54 (step S3). As means for notifying the mobile monitoring device 6, a means using telephone voice may be used.
The operator having received the notification (step T1) uses the mobile monitoring device 6 to make a connection request to the Web server 5 (step T2). The Web server 5 receives the connection request from the mobile monitoring device 6 (Step S4), and transmits an alarm ID input screen (Step S5-3). The mobile monitoring device 6 receives the alarm ID input screen (step T3-3) and, when displaying the initial screen, inputs and transmits the ID number on the initial screen (step T4-3). The Web server 5 receives the screen request (step S6), searches for the corresponding alarm information from the input ID number, and transmits the detailed information to the mobile monitoring device (step S7-3). Based on this, the operator can confirm the detailed situation by using a trend graph or the like, and take necessary measures such as operating a spare device or making contact from anywhere (step T5).
[0019]
According to the third embodiment, since the alarm information can be retrieved from the ID number and the detailed information can be displayed immediately, the operator can display necessary information by a simple operation of inputting only a few digits. It is possible to do.

[0021]
In the fourth embodiment, when receiving the alarm information, the Web server 5 generates a URL of a screen displaying detailed information of the alarm (step S1-4). The mail server unit 53 creates a mail including the URL together with the alarm information (step S2-4), and transmits the created mail to the mobile monitoring device 6 based on the destination information (step S3-4).
The operator receives the transmitted mail (step T1-4), and requests connection to the Web server 5 by selecting a URL included in the mail (step T2-4). The Web server 5 receives the connection request (Step S4), and transmits a detailed information screen of the requested URL alarm (Step S5-4). The operator receives this screen by the mobile monitoring device 6 (step T3-4), and can directly confirm the detailed information of the alarm.
[0022]
According to the fourth embodiment, the detailed information can be directly referred to from the alarm information mail, so that the alarm information can be confirmed with fewer operations.
[0023]
Embodiment 5 FIG.
Hereinafter, a fifth embodiment of the present invention will be described with reference to FIGS.
