ASP (Active Server P)
is one of the extended functions of a web server that dynamically generates a web (Web) page. Normally, a script written in JavaScript or VBSscript that is processed after being passed to a web browser is processed on the server side. Process and send only the processed result to the browser. For example, it is possible to use IIS, which is a Web server of Microsoft Corporation, to receive data from a browser and record it in a file, or to use a dynamic We that cooperates with a database.
You can create page b. The web browser is a system for linking data distributed on a network in a hypertext format, which is attracting attention on the Internet.

As shown in FIG. 2 and FIG. 3, a database is built in the server 10 and the dust collector 30 which is an object to be monitored.
The data collected from a, 30b, 30c, 30d is recorded, and the dust collector monitoring screen can be browsed from the client by the Internet technology. 2 and 3, 13 is a data processing unit, 14 is a database, 15 is a monitoring page, 16 is an automatic page updating unit, 2
1 is a communication function unit forming a part of the first communication line 20;
41 is the Internet which is the second communication line 40, 51
Is an internet browser built in the client 50 which is a maintenance management monitoring unit, and 52 is also the client 5
It is a resident monitoring software built in 0. 2 and 3, the dust collector 30 using the RS-485 line is used.
It is designed to perform data communication with a, 30b, 30c, 30d and communication monitor software.

The received data recorded and stored in the database 14 according to the procedure is converted into a Web screen, the monitoring page 15 can be monitored from the client using the Internet Explorer, and the page on the client side is automatically updated using the JAVA technology. Automatically updated by the unit 16. You can automatically detect alarms by using resident software with automatically updated data, even if you are not viewing the monitoring screen on the Internet browser. JAVA has a special form called an applet, and its feature is that a program is delivered to a client at runtime through a Web browser.

The resident software 52 is the personal computer 50a, 50b, 50c, 50d on the client 50 side.
It is located in. As shown in FIG. 4, the resident software 52 includes a resident program 52 ', an internet browser 53 and alarm software 54. The resident program 52 can activate the Internet browser 53 automatically or manually, and activate the alarm software 54.

More specifically, the dust collector 3 of the monitored part 30
Alarm / abnormality signals from 0a, 30b, 30c and 30d are transmitted to the monitoring server 10. The monitoring server 10 transmits the alarm / abnormality signal to the client 50 via the Internet line 41. In the client 50, the resident program 52 'activates the Internet browser 53 and activates the alarm software 54 to give a voice notification on the message screen.

Therefore, the resident software 52 is installed in the client 5
Since the alarm abnormality can be sensed in real time by incorporating it in the 0 side, it is possible to monitor the dust collecting facility even when other work is being performed on the client computer. The page of the client is updated by the automatic update (Refresh Viewer). It becomes possible to capture new data in real time.

Further, various settings can be made on the computer by setting the resident software 52, and even if the computer is doing other work, the resident message is displayed on the computer by interruption. This allows
Even if the IE browser is not in the monitoring state, and the user does not consciously monitor the dust collection facility, it is automatically monitored, and therefore the safety of maintenance is improved.

FIG. 5 shows the operation flow of the resident software 52. First, initialization is performed as preparation in step S1, and automatic updating is performed in step S2. Next, in step S3, it is determined whether an alarm / abnormality signal has been received. If it has been received, the process proceeds to step S4 to display a message.

This system uses a unique communication method, which is different from the real-time communication that is normally performed. The normal real-time method always polls, for example, 1 to 31 dust collectors, and sends and receives complicated data to and from the dust collectors that responded, but this system takes "procedure" as the communication method. This simplifies the communication contents, and is suitable for the communication of dust collectors that are resistant to noise to build a robust system.

FIG. 6 shows the procedure of the communication system according to the embodiment of the present invention, which is initialized in step S5 and it is determined in step S6 whether or not the refresh has been performed. If it has not been refreshed, the process proceeds to step S7, and it is determined whether or not one hour has elapsed. If 1 hour has not elapsed, the process proceeds to step S8, and it is determined whether 1 minute or 5 minutes have elapsed. If 1 minute or 5 minutes have not elapsed, step S9
Then, the data is stored in the database 14. If it has been refreshed in step S6, the process proceeds to step S10, the equipment information of, for example, 1 to 31 dust collectors is read, and the data is stored in the database 14 in step S9. If one hour has elapsed in step S7, the process proceeds to step S11 to read the setting information,
At 9 the data is stored in the database 14. Furthermore, if 1 minute or 5 minutes have elapsed in step S8, step S8
After reading the observation data in step 12, step S9
The observation data is stored in the database 14.

Regarding refreshing, normally, initial setting is required after completion of construction, but in this system, the setting of dust collecting equipment can be automatically registered by performing a refreshing operation. The refresh is performed manually, and the contents to be fetched include the model name and set values.

When receiving various data from the dust collecting equipment registered by refreshing, the setting data to be set every predetermined time (for example, 1 hour) corresponds to the case where the operator changes the set value, and is 1 hour. Sampling is performed once. Further, the observation data is read every 1 minute or 5 minutes, and the sampling time can be selected from 1 minute or 5 minutes. When storing the received data in the database 14, the data is stored for 10 years.

FIG. 7 shows the processing of the data received from the dust collecting equipment. Initialization is performed in step S13, and the process proceeds to step S14 to determine whether two weeks have passed. If two weeks have not passed, the process proceeds to step S15 and it is determined whether or not it is 24:00. If it is not 24:00, the process returns to step S14. If two hours have passed in step S14, the process proceeds to step S16 to delete and compress the real data. If it is 24:00 in step S15, the process proceeds to step S17, the data is read from the database 14, then the process proceeds to step S18, the data is closed and the processing of the 1-day data ends, and the process proceeds to step S19.
Write data to the database.

In processing the data received by the dust collecting equipment, if the data is continuously recorded on the server at a sampling speed corresponding to the number of observation data of 31 dust collecting equipment, the capacity becomes huge. Therefore, this system uses a unique recording method as shown in FIG. That is, real data (raw data received by communication) is stored for each equipment for up to two weeks. When it exceeds 2 weeks, the real data is averagely compressed. The average compression processing here means the average value of the total observation data when the vehicle is operating during the day. One day is 24 hours, and after 2:00 am, the daily operation data is automatically added. 1
At the end of the day, the data for that day is closed.

The recorded data is converted into a format that can be browsed by the Internet browser 51, and the page is automatically updated by the JAVA script. The year, month, day, day of the week, factory name, overall monitoring, alarm analysis report, alarm occurrence date, etc. are displayed on the screen of each computer. Unlike the panel display of the dust collector, any computer in the Internet environment can freely monitor the operation of a plurality of dust collectors at once on the screen. Also, real-time updated observation data can be displayed by JAVA as an individual monitoring screen.

As shown in FIG. 8, the data communicated from the dust collector also includes alarm information, and this information is judged on the server and displayed on the screen. Further, as shown in FIG. 9, the object of replacement parts is handled as maintenance management data by the automatic link function, and is automatically aggregated to accumulate the maintenance cost.

As described above, by accessing the server 10 from the client 50 by Internet communication,
A large number of users can monitor the operation status of the dust collector at one time. Further, it is possible to obtain a maintenance management system having a maintenance management function, a periodic inspection function, a daily report function, and a report function for the periodical voluntary inspection function. Even if the browser is not activated, the message of alarm abnormality is issued together with the sound on the screen by the function of the resident software 52. In addition, the server 10 periodically sends an e-mail and also delivers the e-mail when an alarm (alarm, abnormality) occurs. Therefore, if the e-mail receiving function is provided, the dust collector can be indirectly monitored even at a remote location. be able to.

[0035]

As described above, according to the maintenance management and monitoring system of the dust collector according to the present invention, an original resident software is incorporated in the computer of the client on the monitoring side, so that an alarm or an abnormality is displayed on the screen. It has a message notification function that allows users to support safety management and performance maintenance of dust collectors without being aware of monitoring. Using the computer at hand that the client has,
The condition of the dust collector can be grasped freely. In addition, this allows the optimum state of the dust collector to be confirmed, extending the operating life of the dust collector and reducing the man-hours required for maintenance and management.
In addition to reducing management costs, Internet technology enables remote monitoring even from remote locations, making manufacturing, sales, and maintenance consistent.
