Design of Alarm Controllers in Detection and Alarm Systems for Gases

Abstract

The paper discussed the main design philosophy of alarm controllers in detection and alarm systems for combustible and toxic gases according to content of national standard, GB 16808-2008. The content of this paper is mainly divided into two parts, program of software and development of hardware. In addition, some key points and problems which should be paid attention to in design and development stage of new product are summarized, including EMC performance, immunity to environment interference and so on.
