Abstract
Development ofgas sensors digital module for industrial safety systems
Incoming article date: 05.06.2018The article describes the development of a wireless monitoring system for toxic and flammable gases control to solve the actual problem of gaseous environment automated control at hazardous production facilities. The architecture of the monitoring system is described, which consists of wireless gas analyzers with connected remote digital modules. The article deals with design and circuit solutions for the development of a gas sensors digital module, which includes: a microcontroller, a RS-485 transceiver, an integrated power supply based on a pulse converter, and a block with digital gas sensors. The principle of the combined protection against electrostatic and microsecond interference is considered, as well as the concept of digital gas sensors with sensing elements of various physical types. The developed module is to detect explosive and toxic gases in the atmosphere, and can be used in emergency prevention systems at the factory together with execution units.
