BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water leakage early detection and warning system having a function of automatically and collectively monitoring the water leakage state of water facilities in a plurality of houses outside the house.

[0002]

2. Description of the Related Art Recently, a so-called home automation system, which is configured to automatically control all devices installed in a house at one place, is becoming popular. One of the most important functions required for such a home automation system is security.

In addition to crime prevention, security functions include electricity,
Including prevention of various accidents caused by failure or abnormality of each facility of gas, water, home automation system with this function constantly monitors the state of each facility,
If there is an abnormality, an alarm is issued to prevent an accident.

Further, some advanced home automation systems are constructed so that equipment inside the house can be automatically monitored and operated from outside the house using a control line. . For example, a system has been developed in which an intercom is used to control various electric devices indoors and outdoors.

[0005]

However, security, fire, gas leaks, locks, etc. have been considered as security functions in home automation systems, but recently they have become a problem in high-rise houses and office buildings. One is a water leak or overflow accident due to loosening of water pipe connections in water facilities such as bathhouses and washrooms, deterioration over time, and the like.

[0006] In particular, when such an accident occurs in an apartment house, if it is left without being noticed as it is, not only the floor becomes wet due to the structure of the building but also the room below it. Causes enormous damage.

[0007] In order to prevent such a water leak accident, when a water leak occurs, the family member is immediately notified of it,
It is desirable to have a system constructed so that when the family member is absent, a notice is sent to the manager's office, the monitoring center, etc. However, since such a system requires a large amount of equipment and is considerably expensive, it is the current situation that it is not widely used.

Therefore, there is a problem to be solved in order to provide a water leakage early detection and warning system which is suitable for high-rise apartment houses and office buildings and has a low cost.

[0009]

In order to solve the above problems, a water leakage early detection and alarm system tem according to the present invention comprises a water leakage detector in a house, a detection signal processing unit connected to the water leakage detector, and a house. A leak early detection alarm system having a detection signal processing unit and a monitoring unit electrically connected to the outside, wherein the detection signal processing unit sends a warning signal to the monitoring unit when the leak detection signal from the leak detector is received. And the monitoring unit is configured to issue a water leak alarm upon receipt of this alarm signal.

In the water leakage early detection alarm system tem according to the present invention, the detection signal processing unit is composed of a plurality of slave units and a master unit of an intercom having a security function.

[0011]

With the above structure, when water leakage occurs, the water leakage detector detects it and sends out a water leakage detection signal. When the detection signal processing unit receives the water leakage detection signal, it generates an alarm signal and transmits it to the monitoring unit through the intercom line. Upon receiving this warning signal, the monitoring unit issues a warning sound and a water leak warning by a lamp.

When the detection signal processing unit is composed of the intercom master unit, when the intercom master unit receives the water leakage detection signal, the intercom master unit turns on the lamp and simultaneously outputs an alarm sound from the speaker and generates an alarm signal. This is transmitted to the monitoring unit through the intercom line. Upon receiving this warning signal, the monitoring unit issues a warning sound and a water leak warning by a lamp. In this way, a water leak warning can be issued both indoors and outdoors.
