Abstract

The invention discloses a fog and haze on-line monitoring device composed of a controller module, a power source management module, an external storage module, a signal acquisition module and a display module. A dust sensor in the signal acquisition module adopts a GP2Y1010AU0F module which can send the acquired dust concentration to the controller module in a form of a standard voltage signal; a sulfur dioxide sensor converts acquired information into a current signal, the current signal is converted into a standard voltage signal by an IV circuit and then is sent to the controller module; the controller module converts the voltage signals of two monitoring parameters into digital signals by an internally-integrated AD converter, and concentration information is displayed on a liquid crystal display screen LCD19264 after the signals are subjected to processing calculation. The device can real-timely and on-line complete the fog and haze monitoring task.

Description

technical field [0001] The invention belongs to the technical field of embedded systems, and in particular relates to an online smog monitoring device. Background technique [0002] Haze is the aerosol system composed of dust, sulfuric acid, nitric acid and other non-aqueous substances in the air that causes visual impairment. Smog is mainly composed of carbon dioxide and respirable particulate matter. Smog is extremely harmful to the human body and can easily cause upper respiratory tract infection, bronchial asthma, lung cancer, conjunctivitis and other diseases. In 2014, my country included smog weather as a natural disaster. [0003] A sensor is a device or device that can sense a specified measured value and convert it into a usable output signal according to certain rules. [0004] Embedded systems are application-centric, computer-based, dedicated computer systems with tailorable hardware and software, and strict requirements for functionality, reliability, cost, v...
