A system for wirelessly transmitting and receiving self-powered power-free fixed temperature type fire detection, the system comprising:
- a self-powered fixed temperature type fire detector (10) operating by the heat generated by fire occurrence and self-powered;
- a receiver (20) for receiving and monitoring a fire occurrence signal through wireless communication according to the operation of the self-powered fixed temperature type fire detector (10);
- and
- an application part (30) for allowing the signal received from the receiver (20) to be notified in real time,
- wherein the self-powered fixed temperature type fire detector (10) comprises:
- a detecting part (100) for detecting, if a temperature caused by the fire occurrence is above a pre-determined temperature, the temperature to thus operate;
- and
- a dust and water-resistant self-powered operating part (200) operating cooperatively with the operation of the detecting part (100) to transmit a fire occurrence signal to the receiver (20),
- the detecting part (100) comprising:
- a top cover (110) connected to the dust and water-resistant self-powered operating part (200);
- a spring cover (120) connected to the top cover (110);
- a push protrusion (130) inserted into the spring cover (120), coming into contact with the dust and water-resistant self-powered operating part (200), and operating the dust and water-resistant self-powered operating part (200);
- a shape memory alloy spring (140) disposed inside the spring cover (120), extended and compressed through shape memory displacement by the high temperature heat generated by the fire occurrence, and pressing the push protrusion (130) serving as a switch to operate the dust and water-resistant self-powered operating part (200);
- and
- a return spring (150) disposed inside the spring cover (120) to return the push protrusion (130) to the original state thereof under a situation where the shape memory alloy spring (140) is automatically returned to the original state thereof if the temperature is returned to a normal temperature after fire extinguishment,
- the dust and water-resistant self-powered operating part (200) comprising:
- a base (210) having partition walls (212) adapted to form an accommodation portion (211) thereon;
- a self power generation module (220) disposed inside the accommodation portion (211) and performing self power generation;
- a transmitting module (230) electrically connected to top of the self power generation module (220), receiving the output generated from the self power generation module (220), and transmitting a radio signal to the receiver (20);
- a dust and water-resistant member (240) disposed on tops of the partition walls (212) of the base (210) to seal the accommodation portion (211);
- and
- a middle cover (250) surrounding the outer surfaces of the base (210) and fixedly connected to the detecting part (100) by means of bolts (B),
- the dust and water-resistant member (240) comprising seating portions (241) formed on the outer surfaces of the lower ends thereof to be seated onto the partition walls (212) and a contact portion (242) formed at the central portion thereof to be pressurized by the press operation of the push protrusion (130) to allow the self power generation module (220) to perform the self power generation,
- the contact portion (242) being corrugatedly formed so that when the push protrusion (130) is pressed, the contact portion (242) is pressurized to minimize the change in air pressure, to operate the self power generation module (220) gently, and to be returned quickly to the original state thereof, and
- a method for registering the self-powered fixed temperature type fire detector (10) onto the receiver (20) is carried out by means of the pressurization of the entire surface of the spring cover (120) through which the spring cover (120) having given flexibility is pressurized to press the push protrusion (130) so that the dust and water-resistant self-powered operating part (200) operates, or by means of the pressurization of the push protrusion (130), without any movement of the spring cover (120).
