Description

Technical Field [0001] The present invention relates to a remote monitoring system for a buried pipe,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote integrated management system for a buried piping, and more particularly, to a remote integrated management system for a buried piping capable of integrally managing the corrosion state and operation state of pipelines buried in the ground remotely.

In general, buried pipelines of metal such as gas pipelines, oil pipelines, and water supply and sewer pipes buried in the ground are used to electrically prevent corrosion, which is a result of an electrochemical reaction.

The electric system is a method for suppressing corrosion by artificially controlling the potential of the object to be protected (corrosion prevention). Typically, there is a cathodic protection system for cathodically buried piping. The method is divided into a sacrificial anode method and an external power source method.

The sacrificial anode method is a method of negatively interposing a buried pipe by electrically connecting a metal having a high ionization tendency (usually magnesium is used) in the electrolyte to act as an anode.

In the external power supply method, a cathode (-) of a DC power supply or a rectifier is connected to a buried pipe, and a positive current (+) is connected to an anode member disposed under the buried pipe to apply a method current (corrosion current). For example, a steel pipe has a natural intrinsic potential of -400 to -500 kPa. In this state, metal ions transport electricity and corrode, so it is usually about 300 을 To keep the potential below -850..

In this way, high pressure gas or water flows through the buried piping to prevent corrosion. Therefore, it is very important to manage whether or not the electrical system to prevent corrosion is correctly performed, so that the method potential is measured regularly once or twice a year. A prior art related to this is disclosed in Utility Model Registration No. 20-0353153 entitled " reference electrode " used for measuring the method potential of a buried metal structure.

On the other hand, in order to measure the method potential, the manager proceeds by connecting a potential measuring device to a plurality of test boxes (TB) installed on the road. Each of these test boxes is provided with lead wires, i.e. buried pipes and buried And both lead wires connected to the reference electrode are connected.

However, in order to measure the method potential, the manager performed repetitive actions such as connecting the ground rod of the potentiometer that opens and closes the equipment lid installed on the road to the exposed electrode, and the measured potential The administrator has to go through a cumbersome process such as manually inputting data into a computer or printing data for analysis. Therefore, in reality, it takes more than 30 hours to monitor one buried pipe, and the workload is excessively increased.

In addition, since the test box is installed along a buried pipe installed along the road, the possibility of collision with the vehicle running on the road always exists in the process of measuring the method potential through the test box by the manager, and when the traffic volume is large, And the like.
