Title:
SELF-POWER GENERATING SYSTEM MONITORING OPENING/CLOSING OF GAS VALVE IN WIRELESS AND REMOTE MANNER
Document Type and Number:
WIPO Patent Application WO/2021/261661
Kind Code:
A1
Abstract:
The present invention relates to a self-power generating system monitoring opening/closing of a gas valve in a wireless and remote manner, which performs self-power generation in accordance with opening and closing operations of the gas valve so as to immediately monitor the opening and closing states of the gas valve in a wireless manner, thereby improving safety by means of a rapid response. The system comprises: a self-power generating gas valve opening and closing detector which is capable of self-power generation, and which is connected to a gas pipe and is operated through self-power generation in accordance with the opening and closing of the gas valve; a receiving unit which receives the opening and closing states of the gas valve in accordance with the operation of the self-power generating gas valve opening and closing detector through wireless communication and monitors the states; and an application unit which enables real-time notification of a signal transferred through the receiving unit. The self-power generating gas valve opening and closing detector comprises: a body holder unit connected to the gas pipe; a body unit connected to a valve lever on the top of the body holder unit; a valve opening and closing unit which is connected to the body holder unit through the body unit so as to allow the gas pipe to be opened and closed by means of rotation; a rotator mounted in the body unit and operating in accordance with the opening and closing operations of the valve opening and closing unit; and a dustproof/waterproof self-power generating detection unit mounted in the body unit and performing self-power generation in accordance with the rotation of the rotator.
