Marine pollution measurement system {MARINE POLLUTION MEASUREMENT SYSTEM}

The present invention relates to a marine pollution measurement system that can measure the degree of marine pollution by measuring various pollutants present on the sea floor with a sensor.

More specifically, in order to measure a variety of marine pollution, a plurality of sensor modules modularized by various sensors are arranged in water to measure information on marine pollution in real time, The present invention relates to a marine pollution measuring system capable of selectively using various sensors according to environmental requirements and having excellent usability, and having a communication network connection unit to enable communication among a plurality of sensor modules underwater, thereby enabling an overall measurement in a large scale ocean.

With industrial and urban development, the emissions of factory wastewater and household sewage have been continuously increasing, and the marine pollution has also increased, leading to the destruction of the ecological environment.

With the emergence of such marine pollution severity, it is necessary to constantly measure the extent of marine pollution in order to prepare for immediate measures against marine pollution.

In recent years, in order to measure the pollution of the ocean, samples are collected through continuous observation of the ocean, and they are transported to the laboratory, and the pollutants are extracted and refined through chemical analysis using expensive equipment.

However, the method of measuring marine pollution involves collecting samples through manpower. Using these quotations, it is difficult to collect samples in the event of various natural disaster requirements, resulting in inefficiency and increased costs due to manpower management.

In addition, it takes a long time to obtain the result of the marine pollution, and there is a problem in that it is delayed in the ocean where the pollution has already occurred, and the cost for measurement of marine pollution is increased due to the chemical analysis using expensive equipment .

Accordingly, various techniques for measuring the degree of contamination at all times have been developed in order to provide an immediate measure against marine pollution.

As one of various technologies for measuring marine pollution, a water pollution monitoring system is disclosed in Patent Publication No. 10-0682127.

FIG. 1 is a view showing an example of a conventional water pollution monitoring system, and is configured to detect various types of contamination through various sensors including a DO sensor, a temperature sensor, a COD sensor, an SS sensor, a pH sensor, and an EC sensor.

However, in the conventional water pollution monitoring system, various sensors are provided to detect various types of contamination. However, it is difficult to configure the water pollution monitoring system by changing the configuration of the sensor depending on the type of pollution at the place where the pollution measurement sensor is installed. There is a problem in that the efficiency due to use is lowered.

In addition, when the battery of the measuring apparatus is replaced or a problem such as various faults or errors occurs, there is a problem in that it is difficult to check the state of the measuring apparatus in a state where the water and the sensor are in contact with each other, .

At this time, the integrated control system 10 may be provided in the form of a terminal, and may be formed as a separate reader for use in various application services.

The term " terminal " means that a terminal and a reader can communicate with a sensor module 20, which will be described later, through a communication network, and means a device capable of at least one communication among Internet communication, voice communication, data communication, do.

For example, a desktop computer installed in a control facility, a smart phone, a tablet PC, or a PDA.

As described above, the integrated control system 10 may include various devices and systems in which a communication network is formed, and may have any structure as long as it can communicate with the sensor module 20 within a predetermined distance. Of course.

The sensor module 20 is capable of measuring various kinds of contamination information of the ocean through various sensors, sharing the measured measurement information between different sensor modules 20, and communicating with the integrated control system 10 through a communication network .

Here, the measurement information means an indicator capable of measuring various kinds of contamination and distinguishing the contamination according to the type of the marine pollution measured.

At this time, a SDP (Session Description Protocol) stack may be included in the measurement information.

Here, the SDP stack refers to a format defined to provide information necessary for discovering and participating in a multimedia session. For example, if pH (hydrogen exponent) is measured measurement information or Do (dissolved oxygen) Whether the measurement information is measured or whether Cl (Chlorine) is the measured measurement information, or whether mixed liquor suspended solid (MLSS) is the measured measurement information or COD (chemical oxygen demand) The type of contamination can be classified by transmitting the measured information together through the communication network.

Depending on the design conditions, the sensor module 20 may be configured to communicate management information in addition to the measurement information when communicating with the integrated control system 10.

Herein, the management information refers to information regarding the remaining amount of the battery 150 provided in the sensor module 20, a failure or error generated in the sensor module 20, and a checking period of the configurations. When the abnormality is detected in the sensor module 20, it is possible to communicate with the integrated control system 10.
