Abstract

Disclosed are a smart test point (T/P) system for automatically detecting a leak of a heat pipeline and a method thereof. The smart T/P system for automatically detecting a leak of a heat pipeline comprises: a smart T/P connected to a leak detection line to detect a leak of an underground heat pipeline and wirelessly transmitting leak detecting data by detecting the leak of the heat pipeline using the connected leak detection line; and an inspector terminal receiving the leak detecting data from the smart T/P. According to the present invention, the smart T/P system for automatically detecting a leak of a heat pipeline and the method thereof can automatically detect an accurate leak point and a disconnection point as all smart T/Ps directly detect the leak or the disconnection using the leak detection line. Specifically, the smart T/P system for automatically detecting a leak of a heat pipeline transmits the leak detecting data from the smart T/P to the inspector terminal via short-distance wireless communications. So, the smart T/P system for automatically detecting a leak of a heat pipeline can accurately detect the leak and the leak point just by an inspector patrolling along a loop circuit plan with a pipeline patroller. Also, the smart T/P system for automatically detecting a leak of a heat pipeline can find a neglected multi-disconnection point and reduce blind spots of leak detection.

Description

Smart T / P system and its method for automatic leakage detection of heat transport pipes {Smart TEST POINT SYSTEM FOR AUTOMATIC LEAK DETECTION OF HEAT TRANSFER PIPE AND METHOD THEREOF}

The present invention relates to a smart T / P system and a method of the heat transport pipe, and more particularly, to a smart T / P system and method for the automatic detection of leakage of the heat transport pipe.

1 is a schematic diagram of leak detection of a heat transport tube according to the prior art, and FIG. 3 (A) is a schematic diagram of disconnection detection of a conventional heat transport tube.

Heat transfer pipes buried underground are not easy to quickly identify leaks when leaks occur, it is also difficult to know the exact leak point.

Accordingly, the leak of the underground heat transport pipe is detected through the leak detection system of the heat transport pipe as shown in FIG. 1.

Referring to Figure 1, each heat transport pipe is connected to form a long pipe. Each leak detection line extends to an adjacent heat transport tube and is connected to a test point 10. The test point 10 is provided with only connection terminals, and connects each leak detection line through the connection terminal to form one large loop. Form a loop line approximately 1 km long.

Here, the main panel 20 may detect a leak by measuring a change in a leak detection line, and recognize a leak through an existing system. In most cases, the leak detection line is normally detected by installing such an existing system. However, as shown in (A) of FIG. 3, many leaks occur because the old leak detection line does not overcome the fluid pressure in the heat transport pipe. If the leak detection line is broken even though the piping is normal, the current automation system cannot identify the leak location. In particular, in the case of multiple disconnection lines in which two or more leak detection lines are broken, it is impossible to predict whether or not a leak occurs in the loop section between the broken leak detection lines.

In cities where old pipes are laid, such as Bundang, Gangnam, and Ilsan, many leak lines of such leak detection lines occur, and the utility and utilization rate of the system is rapidly dropping. Is the current way. This method is called interval check.

However, finding the exact leak point manually is not easy. In one loop, approximately 80 to 90 pipes are connected under the ground as complicated as the circuit of the electromagnetic plate. Underground piping condition is complicated, it is not easy to find the abnormal section by relying on the loop connection drawing for the section of test points 10 T1 to T10, and considerable time and professional manpower are required. It would be even more difficult without a loop connection drawing.
