Wireless sensor network based farm air quality monitoring system

Abstract

The invention discloses a wireless sensor network based farm air quality monitoring system which comprises a data acquisition front, a middle management server, a monitoring center server and a client which are in communication connection with one another. The data acquisition front is used for acquiring farm air quality data and transmitting to the middle management server, and the middle management server transfers the received farm air quality data to the monitoring center server; meanwhile, working conditions of sampling nodes are controlled, network congestion is effectively alleviated, timeliness, stability and effectiveness of the data are guaranteed, and remarkable effect in prolonging service life of wireless sensors is achieved; the monitoring center server is used for centralized processing and storing the data, a user logs on the client to check real-time monitoring information on the air quality of the nodes in a farm, effective measures are timely taken to reduce air pollution levels according to air pollution degree in the farm, and agricultural products planted and bred in the farm are ensured to be green and free of pollution.

Description

technical field [0001] The invention belongs to the technical field of agricultural production and relates to an air quality monitoring system, in particular to a farm air quality monitoring system based on a wireless sensor network. Background technique [0002] "Food is the most important thing for the people, and food safety is the first priority." However, food safety issues occur from time to time, and the harm and losses caused are distressing. Food safety issues are related to the daily life of the majority of people and are closely related to everyone. Safety The food brought to us is not only to fill our stomachs, but more importantly, to meet our needs for safe, safe, green, and non-life-threatening safe food. [0003] Food safety needs to be controlled from the source, real-time monitoring of the environment of the agricultural base, and air, soil, and water quality must meet the standards. A good ecological environment can breed high-quality products, and high-qu...

Problems solved by technology

However, due to the limited bandwidth of wireless sensor communication, a large amount of data may cause network congestion during transmission and cause data distortion, which brings difficulties to data analysts

At the same time, the energy of wireless sensor nodes is limited, and it takes time and effort to replace batteries in practical applications. Therefore, it is necessary to design a node sleep scheduling mechanism to schedule wireless sensors to ensure that the communication network is smooth and can obtain effective numbers while balancing the energy of each sensor node. Consumption, prolonging the service life of the wireless sensor network, the case arises from this
