Greenhouse Environment Parameters Monitoring and Control System Based on Master-Slave Combined
According to the needs of environment parameters monitoring and control in greenhouse, a master-slave combined system of distributed monitoring and control is designed. The system consists of the master control unit and the different types of slave module. By using single chip computer STC12C5A32S2, the master control unit realizes direct monitoring and control of temperature and humidity and CO_2 concentration, makes fuzzy control operation by focusing on various greenhouse parameters, and displays all the parameters and current control state of greenhouse on LCD. The slave module has two parts: the soil moisture monitor-control module and lightintensity monitoring -control module. In this structure, the data storage amount of master microcontroller is large so that the fuzzy control expert system is easy to realize data storage, modification and system upgrade, easy to operate, can shows more information user-friendly, establishes a friendly human-computer interactive interface; and some parameters monitoring-control are focused on the master, which reduces the slave number and increases the system reliability; lastly, different types and number of slave can be chosen according to production needs to achieve partition or block control of greenhouse.
