According to the structure of the present invention configured as described above, the data transmitted from the monitoring and control facility side
The client terminal can monitor and control the water treatment facility (on-site facility) at a location other than the monitoring and control facility via the communication server and the monitor and control server. In other words, the monitoring and control of the water treatment facility can be performed at the center facility (monitoring control). Server), and the client terminal only issues instructions to the monitoring and control facility side. Therefore, it is possible to reduce the load on the client and build a monitoring and control network system for the water treatment facility with a simple system. There is an effect that can be.

At this time, the communication between the controller and the supervisory control server is packet communication employing TCP / IP, and the use of a packet communication network in which the amount of the packet is charged makes the communication fee unnecessarily high. In addition, by using wireless communication or the like, there is no need to connect the controller and the monitoring control server with a dedicated line, and it is possible to reduce the initial setting cost of the facility.

Further, the communication server is a web server that supports a markup language based on HTML, and the communication server and the client terminal communicate with each other using HTTP and TCP / IP.
Each client terminal communicates by packet communication adopting the Internet, and the communication network between the communication server and the client terminal is the Internet, so that each client terminal transmits a web page transmitted from the communication server (web server) to the WWW (World Wide Web). You can check the status of the on-site facilities by viewing the Internet via the Internet, and remotely control the monitoring and control server by sending instructions to the web server from the web page to remotely operate the water treatment facility (controller). be able to.

That is, a terminal (computer) having a browser capable of displaying the web page as a client terminal, for example, a personal computer, a mobile phone, or a PDA capable of starting a known web browser is used. Therefore, there is an advantage that a device for remotely controlling or monitoring the water treatment facility (field facility) can be arranged relatively inexpensively and can be easily added, and the expandability of the system is improved.

In particular, by using a personal computer for the client terminal, maintenance (monitoring and remote operation) of the water treatment facility can be easily performed at a low cost. There is also an effect that maintenance can be performed in various places, and even when the on-site facility is maintained near the water treatment facility, the maintenance can be performed without directly operating the on-site facility.

Also, when the site facility is maintained at the monitoring and control facility, a special interface (GUI) for performing maintenance at the monitoring and control facility is provided on the monitoring and control server by accessing the communication server from the client to the communication server. There is also the advantage that there is no need to provide

Further, a web page transmitted from the monitoring and control facility (communication server) for the client terminal becomes an interface (GUI) for monitoring and control, so that the system is updated on the monitoring and control facility side (software or hardware). The update is completed by updating the system, and the system can be easily updated.

On the other hand, by providing an alarm display device for receiving data from the monitoring control server via a network capable of communicating with a computer and notifying an abnormality of the site facility, the site facility can be viewed without viewing the web page from the communication server. There is an effect that the abnormality of can be easily recognized. In addition, the status of the site facility is distributed to the administrator (monitoring controller) by e-mail, and the administrator receives the e-mail from a portable information terminal such as a mobile phone, and the abnormality (error) of the site facility. Can be easily obtained by an administrator or the like without being greatly affected by the location of the administrator or the like, and in some cases, an abnormality can be resolved by remotely operating a site facility with a terminal that has received an e-mail. Is also possible.

By providing the monitoring and control department with a database server for converting the status of the site facility into a database and storing the database, the continuous operation of the site facility and the history of the measurement results can be stored in a database. Troubleshooting can be easily performed at the time of trouble or the like.
