Research of the Automatic Control System Based on Multi-sensor Data Fusion in Vegetable Shed

Based on the measurement of the environment factors inside the vegetable shed such as temperature, humidity, soil moisture and light intensity, etc, this paper introduces a control system for vegetable shed environment based on the main controller PIC16F873. This system is simple, low cost and enabling human-machine dialogue. And at the same time to improve the reliability of the system the data fusion technology such as the improved voting and fuzzy expert system is applied. Experiments prove that the system can monitor and control the environment factors inside the shed well, and the economic efficiency is improved,so the system has very good prospects of popularization and utilization.
