Title:
SELF-POWERED POWERLESS CONSTANT TEMPERATURE-TYPE DETECTION TRANSMISSION AND RECEPTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/157808
Kind Code:
A1
Abstract:
The present invention relates to a self-powered powerless constant temperature-type detector and wireless transmission and reception system which is wirelessly equipped with a self-powered module that can self-power a fire detector using a shape memory alloy (SMA) that detects fire, and a transmission module, and which can maximize dustproofing and waterproofing efficiency, the system being characterized by comprising: a self-powered constant temperature-type fire detector that is operated by heat generated in the event of a fire and is capable of being self-powered; a receiving unit that receives, through wireless communication, a fire occurrence signal resulting from the operation of the self-powered constant temperature-type fire detector, and monitors the signal; and an application unit for notifying, in real time, of a received signal received through the receiving unit. In this way, according to the present invention, a shape memory alloy spring set at a specified temperature causes shape memory displacement due to the occurrence of fire and a rise in temperature, thereby stretching the shape memory alloy spring and pushing a pressing protrusion, the pressing protrusion presses a contact part of a dustproofing/waterproofing part to operate a self-powered module and electricity is instantaneously generated from the self-powered module, and the generated electricity supplies power to the transmission module and sends an RF signal to the receiving unit in a short time such that, according to the control of the receiving unit, notification of a fire occurrence situation as well as a fire occurrence location can be immediately performed through the application unit in real time.
