Design and Implementation of Intelligent Control System for Green Building

摘要

To meet the demands of users in green building and to reduce the learning cost by intelligent control system, this paper establishes the overall design framework of intelligent control system for green building, and formulates the specific implementation scheme of system hardware and software, as well as the overall control strategy of the system. We use Kingview and Zigbee ad hoc network technology to establish wireless sensor network, to transmit and store all kinds of sensor data. RS485 bus is adopted to realize switch control of household equipment and irrigation solenoid valve, and Modbus-RTU protocol is used to realize system monitoring and control. Then, the temperature control subsystem based on fuzzy-PID control algorithm is established according to the relevant theory of the fuzzy-PID control algorithm, and the simulation experiment is completed in MATLAB, which achieves better control effect. Finally, through the functional test of the acquisition and the control part of the system, it is proved that the scheme achieves the expected design requirements.
