Research on Android-based video monitoring for greenhouse devices status

According to the requirements of modern greenhouse monitoring and management, the status monitoring module of greenhouse devices is developed based on Android system. CAN bus system is used for the real-time environmental data acquisition and environmental devices control in greenhouse. Remote monitoring system software is developed with Android operating system. In order to ensure the security of automatic control of devices, using the real-time video data provided by the camera, image recognition technologies are studied in the status detection of greenhouse devices to implement devices anomaly detection. The frame subtraction method is used in the detection of fan switch. The background subtraction method and Gaussian mixture model are studied to detect the opening status of ventilation window. The test shows that the system data transmission is stable, the environmental regulation is reliable, the video image is clear and smooth, and the devices status can be detected in real time and reliably. The operation of the status monitoring module of greenhouse devices is simple and the interface is friendly, which satisfies the requirements of remote intelligent monitoring in modern greenhouses.
