This work designed a solar directional tracking system based on Internet of things remote tracking system,de-veloped separately the tracking system ontology and the remote monitoring system.By using offline and real-time control,current solar height angle and azimuth angle were calculated according to monitoring data and were used as the reference in adjusting the angle of photovoltaic panels,so as to improve efficiency of solar photovoltaic panels.The solar directional tracking system body of device layer adopted frame structure design and regulated motor of tracking device by fuzzy PID algorithm.The remote monitoring system of the application layer was designed by B/S architecture and adopted MQTT protocol to interact with the cloud platform.Users can directly access the monitor system through browser to realize the remote state detection,real-time control and data management of the solar directional tracking system.Relevant tests ver-ified that the designed system enables users to control and monitor the operation through the monitoring system,thereby is adequate for remote monitoring of solar directional tracking and has high practicability.
