Description

노후수도관로의 누수감시시스템{WATER LEAKOUT DETECTION AND MONITORING SYSTEM}WATER LEAKOUT DETECTION AND MONITORING SYSTEM}

본 발명은 지하에 매설된 노후수도관로를 주관 및 분기관로별, 담당 구역별로 블록화한 다음 상기 블록의 시점과 종점에 압력측정센서 또는 유량측정센서를 설치하여 측정된 압력값 또는 유량값을 소출력 무선방식으로 출력하므로 담당자의 휴대용 데이터수집기를 이용해 차량을 타고 다니며 모든 데이터를 수집후 관리용 컴퓨터에 연결하면 내장 프로그램에 의해 해당 데이터를 출력할 수 있는 노후수도관로의 누수감시시스템에 관한 것이다.The present invention blocks the obsolete water pipes buried underground, by main and branch pipes, and by zones in charge, and then installs a pressure sensor or a flow sensor at the starting point and the end point of the block to output small measured pressure values or flow rate values. Since it outputs by wireless method, it is related to the leak monitoring system of the old water pipe which can output the data by the built-in program when driving the vehicle using the portable data collector of the person in charge and collecting all the data to the management computer.

인간생활에 있어 물은 없어서는 안될 중요한 물질이며 이것을 생산 하는데도 적지 않은 돈이 소요되고 있는 실정이다. 따라서, 지하매설 수도 관로의 누수측정은, 관로의 특성상 매우 장거리에 걸쳐 매설되어 있으며, 또한 많은 분기점에 연결된 소형 수도관로로 이루어져 있는 관계로 상기 수도관로들이 지나가는 지상의 이상한 증후, 즉 물이 새어 공중으로 솟거나 땅이 함몰되어 있는 상태 등을 보고 육안 또는 신고등으로 쉽게 알 수 있다. 그런데, 이들 수도관로가 소규모로 땅속에서스며들어 버리는 현상일 경우에는 감지가 어렵다는 것은 물론, 이 누수된 물은 이리 저리 옮겨다니며 다른 오염물질과 만나 지하수가 오염되고 있는 실정이다.In human life, water is an indispensable material and it takes a lot of money to produce it. Therefore, the leak measurement of underground buried water pipelines is buried over a very long distance due to the nature of the pipeline, and also consists of small water pipelines connected to many branch points. You can easily see it with the naked eye or report by looking at the state of rising or sinking. However, when these water pipes are infiltrated into the ground on a small scale, it is difficult to detect them, and the leaked water moves around and meets other pollutants and contaminates groundwater.

또한, 지하에 매설된 수도관로의 누수측정은 초음파 발생여부 또는 관로투입장치, 초단파 레이저에 의한 측정과 같은 방법등을 사용되고 있는 바, 이러한 방법은 매설관로의 위치를 정확히 파악하고 있어야 적용(GIS 구축등) 가능하도록 되어 있고 경비 또한 엄청나다. 이것 또한 누수가 발생된 이후의 측정이며, 누수와 동시에 위치를 파악하기 위해서는 현실적으로 많은 어려운 점들이 있었다.In addition, leak measurement of water pipes buried underground uses methods such as the generation of ultrasonic waves, pipeline injection devices, and measurement by microwave laser. These methods are applied only when the location of buried pipes is accurately understood (GIS construction). Etc.) and the cost is enormous. This is also a measurement after a leak has occurred, and there are many practical difficulties in determining the location at the same time as the leak.

한편, 상수도관의 누수를 공급량과 소모량과의 차로 비교하거나 담당직원이 심야에 현장을 돌아다니며 가청음식으로 파악하고 있으나 어느 지점에서 새고 있는지를 알 수 없어 새고있다는 상황만을 감지할 뿐이다. 누수되는 곳을 찾을려면 예상되는 현장에 가서 이곳저곳 진단하며 상당한 시간을 소비하고 있지만 그렇다고 효과적이고 만족할 만한 작업이 되지 못하고 있는 실정이다.On the other hand, water leaks from water pipes are compared with the difference between supply and consumption, or the staff is walking around the field late at night to identify audible food, but it does not know where it is leaking. In order to find leaks, they go to anticipated sites, diagnose them everywhere, and spend a considerable amount of time, but they are not effective and satisfactory work.

또한, 기존의 노후 수도관로에 누수감시시스템을 적용함에 있어 누출검출센서 및 부대설비를 설치하려면 관로를 일일이 되파고 되매우고 재포장하는 등 주로 토목공사가 차지하는 비중이 크고 복잡하며, 설치과정 중 노후 상수관로와 주변 타용도의 관로에 손상염려등을 고려하여 상기 누수감시시스템을 신설관과 같은 방식을 적용하기에 불합리 한점이 많았다, 따라서, 설치가 간단하며 경제적으로 단순한작업등이 될 수 있는 누수감시시스템이 필요하게 되었다.In addition, in the case of applying the leak monitoring system to the old aging water pipeline, the civil engineering works are large and complicated, such as re-packing, refilling and repacking the pipeline to install leak detection sensors and additional facilities. In view of the possibility of damage to the water supply pipe and other nearby pipes, it was unreasonable to apply the leak monitoring system to the same method as a new pipe. The system was needed.

본 발명은 상기와 같은 사정을 감안하여 누수검출을 압력측정이나 유량측정으로 적용되는 누수감시시스템을 발명한 것으로, 노후수도관로가 주관 및 분기관로별, 담당 구역별로 블록화되고 이 블록의 시점과 종점에 압력측정센서 또는 유량측정센서를 설치하여 측정된 압력값 또는 유량값을 소출력 무선방식으로 출력하게 되므로 차량탑재의 휴대용 데이터수집기를 이용하여 모든 데이터를 수집한 다음 관리용 컴퓨터에 연결하면 내장 프로그램에 의해 해당 데이터를 출력할 수 있고, 이들을 유무선 또는 공중통신망과 연결하여 중앙감시망을 구축함으로 노후 수도관로의 누수 감시를 더 정확히 측정하고 경제적으로 설치 운영할 수 있는 노후수도 관로의 누수감시시스템을 제공함에 그 목적이 있다.In view of the above circumstances, the present invention has invented a leak monitoring system in which leak detection is applied to pressure measurement or flow rate measurement, and the aged water pipe is blocked by the main and branch pipes and the area in charge. The pressure or flow rate sensor is installed at the end point to output the measured pressure value or flow rate value by using a small output wireless method. Therefore, all data can be collected using the portable data collector of the vehicle and then connected to the management computer. It can output the relevant data by linking them with wired / wireless or public communication networks to establish a central monitoring network, providing a leak monitoring system of the aged water pipeline to more accurately measure and economically install and operate leak monitoring of the old water pipeline. Has its purpose.
