Agricultural greenhouse harmful gas distributed measurement and control method based on agricultural automation

Abstract

The present invention discloses an agricultural greenhouse harmful gas distributed measurement and control method based on agricultural automation. The method concretely comprises the following stepsof: establishing a system, and establishing monitoring nodes and a ventilation control subsystem; and communicating the monitoring nodes and the ventilation control subsystem, wherein the monitoring nodes employ distributed structures and are installed at different typical positions to perform multi-point distributed measurement of harmful gas concentration through a sensor array and send data andidentification codes of each node to a ventilator control system through a RFID network at the same time, and a main controller of the ventilator control system performs statistics analysis of data of each node. The method provided by the invention can achieve distributed high-precision multi-point detection of harmful gas concentration in the greenhouse, can effectively execute circuit automaticregulation of a ventilator to timely exhaust the harmful gas and has a good utility effect.
