Description

Water and sewage leak monitoring system {LEAKAGE SENSING AND MONITORING SYSTEM OF WATER SUPPLY AND DRAINAGE}

The present invention relates to a water and sewage leak monitoring system in a wireless transmission system of underground facility measurement data, and more specifically, a pipe leak of a water and sewage pipe buried in each region is displayed on the leak monitoring device as data through a corresponding pressure sensor or a flow sensor. Next, it uses the external laptop computer, PDA or portable data transmission / reception device to transmit / receive sensing time zone, area code, stored data and current pressure value or flow rate value to water and sewage leak monitoring system that can analyze and display it on the screen. It is about.

In general, as underground facilities, water pipes, sewage pipes, rainwater pipes, power lines, communication lines, and gas pipelines are buried within a certain depth so that various means can be connected or connected from one area to the next. It extends to the distance of the corresponding destination through the connection point or the connection point using the back.

The water supply pipe of the underground facilities is connected to the main building to the distance of the destination and the final building or house through the pipe of each necessary branch or classification from the main building to smoothly supply or drain the raw water from the water supply. By the way, when transporting water in the main pipeline which is buried underground, when the water leaks at high pressure, the surrounding land gets wet or spewed to the ground, so it can be checked with the naked eye or other methods. It is difficult to detect the leakage of the connection part due to the abnormal condition.

In order to detect the leak, a pressure sensor or a flow detector is installed at the connection part when replacing a new pipeline or pipeline, and when it is leaked, it is checked and notified to the monitoring equipment of the ground or other points to take further measures. Since such leak check is an underground facility, there was a limit in finding the correct distance or point. Therefore, we used various methods and means to approach the nearest point to check for leaks and find points of underground facilities.

In addition, the high water drainage basin is preferentially drained into the lowlands, resulting in a decrease in the efficiency of the drainage basin. Here, the drain can be known as the water pressure difference by the high water level value and the low water level value. Therefore, the function of the drain basin is deteriorated due to the water supply from the highlands.

Applicant installed the auxiliary jacket to check the pressure sensor or the flow rate detector at each connection part of the pipeline for accurate leak check, and systemized to be notified of abnormal symptoms more easily and accurately by connecting wired and wireless to the point connected to the ground. It is developing variously to systematize facility measurement.

By using this development, hydraulic or flow rate data is transmitted from the water supply pipe of the underground facility to each point connected to the above point, and it can be connected to the ground using wired or wireless. Thus, in view of the above situation, users are demanding a new system that can easily and easily check the corresponding data on underground facilities through the Internet network using a personal computer which is currently used a lot.

In addition, not only can the measurement data be visually displayed on the new system, but also the software is developed and used in various ways for the personal computer to be conveniently used by the operator.

The present invention has been invented a new system in view of the above circumstances, the measurement data through the pressure sensor or the flow sensor in the region is expressed in the leak monitoring device and then external laptop computer, PDA or portable data transmission and reception device By transmitting the sensing time zone, area code, stored data and current pressure value or flow rate by using the wireless data, these data can be analyzed on the main computer and visually displayed on the network. The purpose is to provide water and sewage leakage monitoring system in the wireless transmission system of measurement data of underground facilities.
