Gas detection device and detection method

Abstract

The invention discloses a gas detection device and a detection method, and relates to the technical field of gas detection. The gas detection device comprises a microcontroller, a gas sensor which is used for detecting gas density and is connected with the microcontroller through an A / D sensor, a 9-axis attitude sensor which is used for acquiring and identifying information of human body attitudes and is connected with the microcontroller, a wireless communication module which is used for data communication and transmission and is connected with the microcontroller, and an intrinsic safety power source which is connected with the microcontroller and is used for supplying power supply to the gas detection device, wherein the microcontroller is used for acquiring the information of human body attitudes and then determining information of dangerous attitudes, an alarm signal is generated according to the information of dangerous attitudes, and data is transmitted through the wireless communication module, so that early alarm is realized in time. The gas detection device can be used for acquiring and identifying attitudes of a user and transferring early alarm signals in time, so that timely rescue is favored.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a gas detection device and a detection method. Background technique [0002] The gas detection device is an instrumentation tool for detecting and analyzing the gas leakage concentration. The device converts the physical or chemical non-electrical signal collected by the gas sensor into an electrical signal, and then rectifies and filters the above electrical signal through an external circuit. And through these processed signals, display the gas concentration information and control the corresponding modules to realize specific functions such as gas alarm, recording, and analysis. [0003] The gas analysis device can detect hydrogen sulfide, carbon monoxide, oxygen, sulfur dioxide, phosphine, ammonia, nitrogen dioxide, hydrogen cyanide, chlorine, chlorine dioxide, ozone and combustible gases and other gases. Coal mines, mining, municipal, chemical, refining, oil and gas p...

Problems solved by technology

[0004] Due to the complexity of the gas site environment, especially the environment with hidden dangers of gas explosion and toxic gas leakage, production operations and inspection personnel entering or being in the gas site pose a threat to health or even life

Traditional portable and hand-held gas detection devices have a single function, generally only display the gas concentration, and store local records, and alarm when the limit is exceeded

Traditional hand-held gas detection devices generally can only be understood through on-site personnel using intercom equipment for voice reports or video monitoring. When danger arises, users are eager to run and escape, and may not have time to use the intercom to call for help; or when the gas sensor fails or When a fault occurs, the user may have found a gas leak but the detection device cannot detect it. At this time, the user may have fainted and cannot transmit information and alarm in real time, so it is impossible to make an accurate judgment and effectively deal with the front-line scene and timely rescue
