As an example of the communication module 140 for communicating with the operation server 20, a conventional modem for performing TCP / IP communication using the vDSL network may be applied. To the operation server (20).

The various sensors for measuring the pressure, the flow rate, the water level, the flow rate, and the water quality data can be variously applied through known technologies, and a detailed description thereof will be omitted.

According to an embodiment of the present invention, the collecting unit 10 further includes a gas sensor 100 installed on a manhole 1 on which one or more sewer pipes 2 are focussed, as shown in FIG. 3 can do.

The gas sensor 100 is for measuring the concentration of hydrogen sulfide gas generated from the sewage pipe 2. The measurement data is transmitted to the operation server 20 to be described below and the hydrogen sulfide concentration measured from the operation server 20 It is possible to grasp the aging of the pipeline through.

This is because the hydrogen sulfide (H2S) is generated by the reduction of the conversion salt in the biofilm formed in the sewer pipe, and the hydrogen sulfide is oxidized by the microorganism and oxidized to sulfuric acid to cause the corrosion of the conduit. By estimating the degree of corrosion, the condition of the conduit is diagnosed and evaluated.

At this time, it is preferable that the gas sensor 100 is installed as close as possible to a position where hydrogen sulfide gas is generated, thereby minimizing dilution due to other atmospheres.

For example, as shown in FIG. 3, the collecting part 10 may further include mounting means so that the gas sensor 100 can be configured to ascend and descend fluidly according to the water level of the manhole 1.

The mounting means includes at least one guide rail 160 coupled along the side wall of the manhole 1 and a buoyancy spring 150 coupled to a lower portion of the gas sensor 100 and adapted to flow along the guide rail 160. [ ).

The stopper 190 is configured to be able to adjust the position of the stopper 190 so that the stopper 190 can flow at a lower portion of the guide rail 160. The downward flow of the sensor 100 is restricted so that the gas sensor 100 is protected from the sewage contained in the manhole 1 and at the same time the gas sensor 100 is positioned at the upper portion of the invert so that the rain does not occur, Do not disturb the milking.

The operating server 20 includes an input unit 200 and a communication unit. The input unit 200 includes not only the population and area of the area to be managed, but also a housing type, a sewage drainage system, History information such as location information, construction information, dredging information, and specification information of the sewer pipe, which is history information about a plurality of sewer pipes installed in the area, as well as local information. Such input information is used as basic information in the analysis process of the operation server 20 described below.

The communication means receives information data transmitted from the communication module 140 of the collecting unit 10 by using a conventional wired or wireless communication network.

Meanwhile, the operation server 20 receives the information data transmitted from the collecting unit 10 and the data input through the input unit 200 in real time, analyzes the state information of various sewer pipes, and stores and outputs the information And obtains the information requested from the administrator terminal 30 described below and provides the information corresponding to the request information to the administrator terminal 30.

In addition, the sewage pipe evaluation unit 210 analyzes data measured from the gas sensor 100 and predicts the amount of dirt accumulated in the sewer pipe. That is, as shown in FIG. 6, as the hydrogen sulfide rises in proportion to the amount of dirt accumulation in the conduit, the sewage pipe evaluation unit 210 determines the corrosion progress state of the pipe through the hydrogen sulfide gas concentration measured by the gas sensor 100 Of course, when the hydrogen sulfide gas concentration reaches a certain level, the amount of dirt accumulation in the pipeline is predicted and the dredging time is determined accordingly.

As described above, the sewage pipe evaluation unit 210 can determine the overall deterioration and maintenance period of the pipeline by determining the dredging time according to the corrosion state of the pipeline and the amount of dirt accumulation through the input hydrogen sulfide gas concentration.

The quantity analyzer 220 analyzes Combined Sewer Overflows (CSO), infiltration quantity and infiltration quantity (Infiltration / Inflow) on the basis of data transmitted from the collecting unit 10.

As the method of analyzing invasive water, four estimation methods can be applied, such as a method for estimating the amount of water used, a maximum / minimum flow rate evaluation method / day maximum flow rate evaluation method, and a night life wastewater assessment method.

The above water use evaluation method evaluates the average value of the measured flow rate as the invasive water quantity obtained by subtracting the sewage water discharge amount estimated from the constant usage amount.

That is, the amount of infiltration = the measured amount of sewage - (the amount of water used × the conversion rate of wastewater), and the wastewater conversion rate is usually 0.8 to 0.9.

The daily maximum / minimum flow rate is calculated by subtracting the amount of nightly industrial wastewater from the daily minimum wastewater calculated from the average value of the measured flow rate. The inflow rate is the minimum wastewater amount per day - the amount of factory wastewater (based on 24-hour operation).

The daily maximum flow rate is calculated by subtracting the minimum value of the daily minimum sewage from the maximum value of the daily minimum water flow calculated from the measured flow rate. Finally, the night life wastewater assessment method evaluates the amount of inflow by subtracting the amount of night living sewage and the amount of factory wastewater from the daily minimum water amount of the measured flow rate.

In the present invention, the average of the remainder obtained by subtracting the maximum and minimum of the inflow water calculated by the four estimation methods is considered as the infiltration water and is analyzed comprehensively.

When the inflow water is analyzed, it is calculated by the flow rate during rainfall and the average flow rate during the dry season, and the flow rate during rainfall is subtracted from the dry season average flow rate to select the total inflow amount.

On the other hand, the sewage leak analysis unit 230 of the operation server 20 analyzes the leakage of the pipe based on the measurement data transmitted from the collection unit 10.

In addition, the pollution load unit intensity analyzer 240 analyzes the sewage generation amount and the pollutant load based on the data transmitted from the collecting unit 10 and the input unit 200.

The sewage pipe failure analysis unit 250 analyzes the combined amount of sewerage overflows (CSO) analyzed through the water analysis unit 220, the sewage leak analysis unit 230 and the pollution load unit analysis unit 240 Determine the difficulty of the pipelines through infiltration quantity and infiltration quantity (I / I: infiltration / inflow), the exfiltration of the pipelines and the information of the unit level, and determine the time of renovation and determine the priority.

In addition, the operating server 20 is configured to perform a conditional search. To this end, the operating server 20 further includes a database 280 in which received measurement data and self-analyzed result data are stored (Flow rate, flow rate, water level), data of the correlation between items (flow rate, flow rate, water level), water quality data And the analysis of rainfall events.

In addition, the operation server 20 further includes an abnormal state detection unit 270. The abnormal state detection unit 270 detects the abnormal state of the various measuring instruments constituting the collecting unit 10, And provides the contents of the meter and its failure state to the administrator terminal 30 and the manager when the abnormal state is detected.

The abnormal state detection information is transmitted to the manager through an information transmission medium such as SMS, E-mail, or Fax.

The operation server 20 further includes an information providing unit 250 for extracting information requested from the administrator terminal 30 described below from the database 280 and transmitting the request information to the administrator terminal 30, ).

Meanwhile, the administrator terminal 30 is configured to provide various information necessary for monitoring the sewer pipe to the manager. The manager terminal 30 is connected to the operation server 20 and displays result information analyzed and processed in the operation server 20 in real time .

In particular, the administrator terminal 30 includes a GIS-based sewage pipe map providing unit 310. In the operation server 20, the connection status of the sewer pipes provided on the area to be managed and the direction of the sewage It is possible to monitor through the sewerage map of the corresponding region by grasping the state of convergence of the step by step and providing it to the manager terminal 30. [

In the present invention, the configuration of the protection unit 400 for protecting the gas sensor 100 is further implemented, as shown in FIG. 7, including the configuration described above.

The protection plate 410 may have a rectangular shape and may be formed with a curved surface portion 411 protruding upward in the central portion and having a hemispherical shape.

This is so that the pressurization by the sewage or the like falling from the sewer pipe 2 can be dispersed.

The curved surface portion 411 may be provided with a transparent visible window 412 for visually checking the state of the gas sensor 100.

It is preferable that the protection plate 410 has an outer circumference extending outwardly from the buoyancy member 150 to prevent the sewage falling from the sewer pipe 2 from approaching the gas sensor 100.

The support plate 420 has the same shape as the upper periphery of the buoyancy member 150 and is formed at the upper part of the buoyancy member 150 so that the gas sensor 100 passes through the hollow 421 at the center. Lt; / RTI >

The support bars 430 are coupled to the support plate 420 by welding or the like so that the support bars 430 are positioned at both sides of the gas sensor 100 and the upper portion of the support bars 430 passes through the protection plate 410.

The protection plate 410 is coupled to the support bar 430 in such a manner that it can be raised and lowered while a through hole 413 through which the upper portion of the support bar 430 passes is formed on both sides.
