Design of Greenhouse Environmental Detection System Based on AHP Comprehensive Fuzzy Evaluation

Abstract

Because greenhouse is not influenced by external climate and regional environment, it has become a trend in crop cultivation. Building a method that evaluates the fitness of greenhouse for crop has a great significance for the development of greenhouse. In this paper, a design of greenhouse environmental detection system based on AHP (analytic hierarchy process) comprehensive fuzzy evaluation is proposed to approach the goal of evaluation. Multiple sensors are used to detect environment and the wireless transmission network based on Zigbee is used to transmit environmental data. The temperature, air humidity, illumination, CO2concentration and soil moisture are used as the evaluation factors. The appropriate membership function is selected to build the membership matrix and the AHP is used to construct the weight vector set. The environment of greenhouse can be evaluated by the calculation of membership matrix and weight vector set.
