Universal method for detecting toxic gas and alarming and instrument

Abstract

The invention relates to a universal method for detecting toxic gas and alarming and an instrument thereof. In the method, a basic module, a universal interface unit of a toxic gas sensor and a wireless communication universal interface unit are adopted. The basic module comprises a central processing unit, a one-key on / off and power supply management unit, a temperature and humidity detecting unit, a real-time clock unit, an alarm unit and a human-machine interface unit, and can be used for completing one-key on / off management, toxic gas detection signal processing, battery power detection, temperature and humidity signal processing, real-time clock signal processing, alarm control and strategy management, human-machine interface control and output wireless signal transmission management. The instrument integrates a toxic gas detection interface function, a temperature and humidity detection function, an alarming function of various manners, and various wireless communication interface functions into a whole, and is convenient to carry on and simple and convenient to operate, and toxic gas sensor modules and wireless communication modules of different manufacturers can be replaced as required.

Description

technical field [0001] The invention relates to a general method and an instrument for toxic gas detection and alarm. Background technique [0002] With the improvement of people's living standards, the demand for energy is increasing, and various petroleum, chemical, and natural gas plants continue to increase. In the process of mining and utilization, there are many kinds of toxic and harmful gases (such as hydrogen sulfide, sulfur dioxide, etc.) that threaten people's lives at any time. It is necessary to carry relevant toxic gas detection and alarm equipment to form an early warning system. Once there is a high concentration of toxic gases, it can be reminded in time On-site workers to ensure worker safety. [0003] In the prior art, toxic gas detection and alarm instruments based on a single function have been widely used. However, the existing toxic gas detection instruments generally have a single function, and only have a single function of detecting toxic gases, or...
