Generally, the length of the water pipe is several hundred Km, and the water is supplied with a strong water pressure. Therefore, even in case of a small water leakage, the water leakage portion can be extended in a short time, leading to water damage. There is a problem that the water supply of the water pipe is interrupted frequently.

In addition, during the past period, the water leakage amount of 7.5 billion ㎥ has reached 4.6 trillion won in the amount of financial losses, and it is possible to know how serious the damage is. In case of damages caused by leakage water, the soil is washed away by the strong water pressure in the pipe, , Soil erosion and other dangerous factors, as well as serious damage to people.

Therefore, the problem of permanent leakage of water tap and the necessity of solution are emerged, so that researches are actively carried out.

Therefore, the conventional water leakage detection device is applied by using a sensor type using electricity, a method of directly photographing the inside of a pipe with a camera, a method using a water pressure difference, and the like.

However, the conventional water leakage detection device as described above has difficulty in finding an accurate position of the water leakage and quick response.

On the other hand, as a conventional technique for detecting water leakage, there has been proposed a water leakage detection system using a pulse signal in a liquid pipe through Patent Literature 1 (Registered Patent No. 0462269, Dec. 24, 2004).

However, there is a problem that such a conventional apparatus for catching leakage is difficult to apply to an existing water pipe, and since an electrical signal is continuously transmitted to a lead wire, not only an expensive maintenance cost is caused, but also an external impact is applied to the lead wire, There is a problem that leakage detection of the present invention is no longer possible and maintenance costs for recovering the leakage are considerably generated, which is inefficient.

In addition, personnel accidents due to chemical leaks occur frequently in piping applied to the chemical industry, but in the conventional system, rapid detection and countermeasures against chemical leaks in piping are not achieved.

Therefore, it is possible to detect the color change of the outside of the piping for the piping applied to the chemical industry, and it is possible to detect the leak easily and automatically, and it is possible to detect leakage of piping through alarms and alarms corresponding to the leak (LEAK) It is required to research and develop a piping leakage monitoring system capable of prompt response.
