As shown in FIG. 1, the USN-based real-time water quality monitoring system according to the present invention is installed in a certain range to collect various information of water quality using at least one sensor, and integrates the sensed water quality information data into an integrated gateway ( At least one water quality measuring means 100 for transmitting to the 200, water quality information data received from the water quality measuring means 100 for processing and transmitting to the integrated control means 400 through the Internet network 300 The water quality is analyzed using at least one integrated gateway 200 and the water quality data information received from the integrated gateway 200, and the water quality information according to the depth sensed by the water quality measuring means 100 is analyzed. It consists of integrated control means 400 for generating three-dimensional water quality information by analyzing, and outputs a warning sound when the water quality data allowance is exceeded On-site emergency dispatch means (500) to notify the SMS to check the pollution source on the site is included, and the web service is provided so that the general user 600 can check the water quality status on the web page through the Internet network 300 It includes a web server (not shown) for.

The water quality measuring means 100 is installed in a plurality of ranges for measuring the water quality to form a primary sensor node.

The network method of the water quality measuring means 100 is preferably a local area network in the form of RF ZigBee (RF ZigBee) to be configured as Non-IP-USN, all the local area communication that can transmit and receive data with Non-IP The method can be applied.

The water quality measuring means 100 transmits the water quality data through the sensor node capable of data transmission to be delivered to the integrated gateway 200.

Water quality monitoring system of the present invention can be divided into Non-IP-USN and IP-USN, the water quality measuring means 100 that is the primary sensor node 100 and the integrated gateway 200 that is the secondary sensor node is Non-IP- It consists of a USN, the Internet network 300 and the integrated control means 400 is composed of IP-USN.
