Description

Smart system for warning water leak

The present invention relates to a water leakage alarm system, which detects an alarm when a pipe leak occurs or the like and alerts the water leakage system.

In general, tap water is purified in a water purification plant, and in the case of a city, each tap is supplied through a large pipe, and each tap is classified into a heavy block and a small block to supply tap water.

In addition, a water meter is installed between each distribution point to measure the flow rate of tap water supplied to the distribution area. In large facilities such as apartment complexes, water pipes may be installed to supply tap water at once through large pipes.

In addition, general homes and shopping centers are connected to small pipes from large pipes laid under the road to supply tap water to end users. At this time, when a small pipe is called a branch line, most leaks occur in the branch line. That is, the branch line is greatly pressured because the pipe is thin, and in a dense area of the house, the joint is connected by a long connection, so that water leakage occurs easily at the joint and the connection part.

In particular, water leaks occur easily in leaky areas such as the sink floor and balcony of the home.The owners of each home do not know the leak immediately and find the leak only long after the leak. This is wasted. As such a large amount of tap water leaks, as well as waste of cost, foreign matter, bacteria, heavy metals, etc. are introduced into the water supply pipe due to the pressure change at the leak location, causing contamination of the water quality.

Therefore, it is necessary to replace and repair old or damaged water pipes by accurately identifying the leak location, and conventional leak detection technology has a limitation in detecting a small amount of water leak. There is a problem that it is not easy to detect leaks in the area immediately.

In the house, many water pipe joints are parts where many defects occur. If a leak is not detected and not repaired, it will cost a lot of money to replace the leaked generation floor, the papering, furniture damage, and repair the leaked house's lower ceiling.

For example, as shown in FIG. 1, a leak of a toilet may cause property damages of 0 to 5 million won due to damage to a luminaire and a bathroom appliance.

In addition, in the case of leaking under the sink, property damage of about 10 to 150 million won may be caused by damage to flooring, ceiling and electronic products.

In addition, in case of a balcony leak, damages of about 20 million won can be caused by replacement of floor drains and cost of floor construction.

In particular, if a critical area such as the bottom of the sink is leaked, the damage will be enormous. Accordingly, the present invention provides a means for immediately detecting a leak in a leak danger area such as a sink bottom or a balcony.

To this end, the smart leak alarm system of the present invention, as shown in Figure 2, a sensor for detecting the leak as a bar bar shape, the leak detection sensor 100 and the leak detection sensor extended by the connector 10 connection, When the leak is detected through the 100, a leak alarm alarm sound output 200 includes a leak alarm. This will be described below.

The leak detection sensor 100 is a sensor that detects leaks, has a bar bar shape, and has a structure that is extended by connecting the connector 10.

To this end, the leak detection sensor 100 includes a PCB substrate 100a, an anode pattern 110, and a cathode pattern 120, as shown in FIG. 3.

The PCB substrate 100a has a bar bar shape. The PCB substrate 100a, as is known, is a printed circuit board, which forms a conductor circuit on the surface or inside of an insulating substrate in order to connect electronic components according to a circuit design.

The anode pattern 110 is a conduction band of a positive electrode patterned with a conductive material along one side edge of the PCB substrate 100a in the longitudinal direction.

The negative electrode pattern 120 is a conduction band of a negative electrode patterned with a conductive material and spaced apart from the positive electrode pattern 110 along the other edge in the longitudinal direction of the PCB substrate 100a.

A cable is connected between the first terminal (not shown) of the leak alarm 200 and the anode pattern 110, and the second terminal (not shown) of the leak alarm 200 and the cathode pattern 120 by a cable. That is, a cathode cable electrically connecting the anode pattern 110 and the leak alarm 200 and a cathode cable electrically connecting the cathode pattern 120 and the leak alarm 200 are provided.

Therefore, in the state where the current flows through the anode cable in the leak alarm 200, when the water does not flow into the leak detection sensor 100 made of the PCB substrate 100a, the current of the anode pattern 110 is It does not flow into the cathode pattern 120.

On the other hand, in the state where the current flows through the anode cable in the leak alarm 200, the water leaks into the leak detection sensor 100 made of the PCB substrate 100a, the anode pattern 110 and The cathode pattern 120 becomes conductive through water, so that a current of the anode pattern 110 flows into the cathode pattern 120. Accordingly, the leak alarm 200 detects a current flowing into the cathode pattern 120 through the cathode cable, and outputs a leak alarm alarm sound when a current is detected through the cathode cable.

When the leak alarm 200 detects a leak through the leak detection sensor 100, the leak alarm alarm sound is output. For this purpose, the leak alarm device has a general CPU computing device configuration. It includes program modules that are implemented through various types of languages such as C ++, Java, Visual Basic, Visual C, and so on. In addition, it may be implemented using an operating program that is variously provided according to an operating system such as general DOS, window, Linux, Unix, Macintosh, and the like.

Meanwhile, in the present invention, the connection between the positive electrode pattern 110 and the positive electrode cable, and the connection between the negative electrode pattern 120 and the negative electrode cable may be connected to the connector 10.

To this end, the PCB substrate 100a has a connector 10 connected to the anode pattern 110 and the cathode pattern 120 at one end as shown in FIG. 4. The connector 10 may be inserted into a hole formed in each of the anode pattern 110 and the cathode pattern 120 of the PCB substrate 100a.

 The connection jack 20 to which the positive cable and the negative cable are connected may have a structure that is fastened to the connector 10. When the positive cable is connected to the first jack end of the connecting jack 20, and the negative cable is connected to the second jack end of the connecting jack 20, the first jack end of the connecting jack 20 is inserted into the positive terminal of the connector 10. The second jack end of the connection jack 20 may be inserted into the negative terminal of the connector 10.

As such, since the PCB board 100a implemented as the leak detection sensor 100 may be connected to the connector 10, the plurality of PCB boards 100a may be expanded and coupled through the connector 10.

For example, as shown in FIG. 5A, two PCB boards 100a may be extended and connected by the connector 10. That is, the first PCB board 100a and the second PCB board 100a are coupled by the connector 10, so that leakage detection is possible in a region where the first PCB board 100a and the second PCB board 100a are combined.

It may also be combined in a bent form as shown in Figure 5 (b). That is, the first PCB board 100a and the second PCB board 100a are coupled by the connector 10, and the second PCB board 100a and the third PCB board 100a are coupled by the connector 10. 'Like the shape of the leak can be detected.

As illustrated in FIG. 6, the leak detection sensor 100 may be disposed along the bottom of the sink to detect leaks without missing the entire sink bottom.

Therefore, it can be installed by connecting the leak detection sensor to the desired position (connector terminal) at a desired position without any additional cost.

On the other hand, the leak alarm 200, when a leak is detected through the leak detection sensor 100, and outputs a leak alarm alarm sound, so that the user can immediately know that the leak has occurred, the valve tube repair Can be taken.

The present invention further implements to automatically handle leakage by a home automation system when a leakage occurs.
