A SECURITY SYSTEM FOR GAS PIPER APARTMENT HOUSE

摘要

A security system for a gas pipe of an apartment house is provided to prevent robbery by promptly informing invasion of an invader through generation of alarm or smoke in case of the invasion. A security system comprises a case, a low speed motor(20), a first gear, a second gear, upper and lower human body sensing sensors(50,51), and a control unit(60). The low speed motor is mounted inside the case and operated by a battery(80). The first gear rotates by being installed on an upper part of a motor axis of the low speed motor. The second gear is engaged with the first gear and installed on a vertical rotation axis rotatably installed by being protruded toward upper and lower parts of the case. The upper and lower human body sensing sensors sense an invader by being installed on upper and lower parts of the vertical rotation axis. The control unit compares a sense signal of the upper and lower human body sensing sensor with a pre-inputted control signal, and then when determining that the invader exists, controls operation of an alarm(70) for a set time.
