a communication module provided inside the main body;
a controller provided inside the main body, when leakage of the sprinkler head is detected by the sensor, a controller for controlling to transmit identification information of various equipment, pipes, and heads in which leakage is detected to a control server through the communication module; and
One end is coupled to the deflector of the sprinkler head, and the other end is coupled to the coupling member to prevent the body from falling to the floor when the body is detached from the sprinkler head due to the operation of the sprinkler head. ,
A part of the coupling member is connected to the head guard member through a low melting point alloy coupling, and the other part of the coupling member is coupled to the deflector of the sprinkler head, and when a certain temperature is reached due to a fire, the low melting point alloy coupling The sprinkler head leakage detection device, characterized in that the connected parts are primarily detached, and the spring structure of the coupling member is secondarily detached by the radiation operation of the sprinkler head.
delete The method of claim 1,
and an indicator lamp formed on one surface of the base frame and flickering or lit when leakage of the sprinkler head is detected by the sensor.
4. The method of claim 3,
Further comprising a solar battery unit,
The solar battery unit is formed on one surface of the base frame, and the power generated by indoor lighting is provided to at least one of the sensor and the display lamp.
