Software closed appliance gas leakage alarm device on basis of gas pressure sensor and strain gauge

Abstract

The invention discloses a software closed appliance gas leakage alarm device on the basis of a gas pressure sensor and a strain gauge and relates to a signal device which takes effects by the pressure of an inflatable object. The software closed appliance gas leakage alarm device comprises a gas leakage signal sending device, a gas leakage signal receiving device, an alarm device and a power supply system, wherein the gas leakage signal sending device mainly comprises the gas pressure sensor, a strain gauge device, a sent signal conditioning circuit, a sending device singlechip and a wireless data sender; the gas leakage signal receiving device mainly comprises a wireless data receiver, a received signal conditioning circuit, a receiving device signalchip, a keyboard and a liquid crystal display; the alarm device comprises an LED (Light-Emitting Diode) lamp and a buzzer; the power supply system mainly comprises a rechargeable battery and a solar cell panel. The device disclosed by the invention automatically gives an alarm when a software closed appliance has the phenomenon of gas leakage or is seriously deformed, solves the problem of incapacity of timely giving an alarm when an existing software closed appliance has the phenomenon of gas leakage or is seriously deformed, and overcomes the defect that in the prior art, an existing gas leakage alarm device can be only used in gas leakage alarm of a tire and has a narrow application range.

Description

technical field [0001] The technical solution of the present invention relates to a signal device acting on the pressure of an inflatable object, specifically an air leakage alarm device for a soft airtight appliance based on an air pressure sensor and a strain gauge. Background technique [0002] Nowadays, soft airtight appliances are widely used in various fields, but there is no effective measure for timely alarming of air leakage of soft airtight appliances. For example, the swimming ring is a soft airtight device. When the user is in the water, the air pressure inside the swimming ring changes or the shape changes, and the swimming ring may leak air, which has safety problems; the sheepskin raft is a soft airtight device, which is filled with air. If it is scratched by a branch in water, it will also leak air; the inert gas storage device is a soft airtight device, and there is also a risk of air leakage due to aging of the material or improper use. If there is a poten...
