Air quality monitoring equipment based on sensor network

Abstract

The invention relates to air quality monitoring equipment based on a sensor network. The prior monitoring equipment and apparatus have various types, thus the data types are not universal. The invention comprises air quality monitoring nodes, a base station and a monitoring center. The monitoring nodes form a network through a self-assembling way, the base station receives air quality parameters acquired by the monitoring nodes, and then processes the data for storage, and the processed data is sent to the remote monitoring center by a GPRS network. Each air quality monitoring node comprises a power management module, an air quality parameter acquisition module, a microprocessor module and a ZigBee radio frequency module. The base station comprises a power management module, a base station microprocessor module, a ZigBee radio frequency module and a GPRS transmission module. The invention is not restricted by geographic environment, thereby being capable of monitoring the air quality change situation in a large-scale region.

Description

Technical field [0001] The invention belongs to the technical field of wireless communication and embedded systems, and specifically relates to an air quality monitoring device based on a sensor network. Background technique [0002] Environment and development are major issues of general concern to the international community today. The research and development of air quality monitoring equipment can understand and evaluate the air quality and better protect the environment. [0003] At present, modern air quality monitoring stations have been successively established throughout the country, which has greatly promoted environmental protection. But it also faces the following problems: 1) There are various types of monitoring site instruments, many data acquisition equipment, not universal, and poor mutual compatibility, there is no standardized communication protocol; 2) On-site monitoring data is usually transmitted to the monitoring center by wire , The communication method is...
