Description
Technical Field
This patent relates to illumination heating technical field, especially is applicable to combustion apparatus's safety device technical field specially.
Background
In recent years, with the increase of the utilization rate of household gas, household gas explosion safety accidents frequently occur, and the gas safety accidents cause serious life and property losses for society and people.
The household gas alarm is installed in places where gas leakage is likely to occur, such as kitchens and restaurants. In the prior art, the core raw component for detecting gas leakage is generally a gas sensor, and as the gas sensor is exposed to gases with various components for use, a shell cover of a household gas alarm is provided with a vent hole. When the concentration of the fuel gas in the air exceeds a set value, the detector is triggered to alarm and sends out sound and light alarm signals to the outside. However, in the environment of more water mist, more oil smoke and the like such as a kitchen, a restaurant and the like, the air holes on the shell cover of the household gas alarm are easy to be blocked, so that the gas alarm generates false alarm or no alarm, and the gas safety of residents cannot be guaranteed under the condition. In addition, the alarm form of the household gas alarm usually only comprises acousto-optic alarm, the intelligent degree is not high, when gas leakage occurs and a user is not at home, the user or the property management platform cannot be informed at the first time, and great hidden danger is brought to the life and property safety of the user.
Common techniques applied:
flame detection module, photosensitive module: shenzhen, Mulitai electronics, Inc., Shenzhen, Ke Yongbang electronics, Shenzhen, Tianshiqian electronics, Inc. have already gained industrialized development.
A flame detection module: the first flame detectors appeared in the last 50 s and 60 s, and first ultraviolet flame detectors were developed abroad, and in the beginning of the 70 s, flame detectors for detecting infrared rays and visible light released during flame combustion appeared in foreign countries, and in the 80 s, boiler combustion monitoring devices based on images and videos appeared, and later flame detectors with combined probes (infrared rays and ultraviolet rays) appeared. The flame detector has stronger and stronger detection discrimination capability so far, and the detection also tends to be intelligent.
An Electrochemical gas sensor (Electrochemical gas sensor) is a detector that measures a current by oxidizing or reducing a gas to be measured at an electrode, and obtains a concentration of the gas to be measured. The gas electrochemical gas sensor is an electrochemical gas sensor specially used for detecting the concentration of methane.
The laser gas sensor is a gas sensor developed based on a tunable laser spectrum absorption (TDLAS) principle, and is not influenced by environment temperature and humidity and not influenced by interference gas through the fact that molecular absorption wavelength of gas is irrelevant to temperature and pressure and the wavelength absorption characteristics of different gas molecules are not interfered with each other. The TDLAS technique is still the preferred technique for accurate analysis of industrial process gases, and TDLAS is the abbreviation for Tunable semiconductor laser Absorption Spectroscopy (Tunable diode laser Absorption Spectroscopy). The technology mainly utilizes the characteristics that the narrow line width and the wavelength of a tunable semiconductor laser are changed along with the injection current to realize the measurement of single or a plurality of absorption lines of molecules which are very close to each other and difficult to distinguish. The basic principle is as follows: Lambert-Beer law. When a beam of light passes through a gas-filled absorption cell, its intensity is attenuated by molecular absorption. The amount of attenuation dI of the intensity of the incident light as it passes through the molecular layer of thickness dl is proportional to the intensity of the light transmitted thereto.
A photosensitive module: a photosensitive sensor is a sensitive device that has a response or conversion function to an external light signal or light radiation. Photosensitive sensors are one of the most common sensors, and are of a wide variety, mainly: phototube, photomultiplier, photoresistor, phototriode, solar cell, infrared sensor, ultraviolet sensor, optical fiber type photoelectric sensor, color sensor, CCD and CMOS image sensor, etc. The major manufacturers in China have OTRON brands and the like. The optical sensor is one of the most productive and widely used sensors, and plays a very important role in automatic control and non-electrometric measurement technology. The simplest photosensitive sensor is a photoresistor that generates a current when a photon strikes a junction.
