Title Based on Single-chip microcomputer wireless smoke
alarm of design and implementation
Abstract
This paper using single sensor, wireless technology with developed and designed a set of the smoke control system,to photoelectric sensor and single chip microcomputer as the core and with other electronic technologies, realize the program under the control of the smoke alarm. When there is a fire, smoke signal acquisition circuit (general by smoke sensor and amplifying circuit component) will smoke signal into analog signals. Module circuit will convert from smoke detection circuit sent the analog signal conversion into single chip can identify the digital signal into the wireless module after. Wireless module through the signal encoding/decoding processing to microcontroller, single chip microcomputer to receive signal, the digital signal filtering processing, and the treatment of the analysis of the data, realize smoke alarm. Alarm more intelligent and information.
