Real-time detection is performed, and each temperature sensor 2, humidity sensor 3, air quality monitoring device 4 and microorganism detection device 5 communicates with the control system through wired or wireless communication respectively, and then transmits its detection data to the control system in real time. The control system includes a processor, a controller, a display, a parameter input module and a data recording management module. The parameter input module can set the operating conditions of the ultraviolet generating device 1 and the ventilation equipment 6. The processor can analyze and judge whether disinfection is needed in the agricultural product warehouse according to the conditions set by the parameter input device and the detection data of the temperature sensor 2, humidity sensor 3, air quality monitoring device 4 and microorganism detection device 5. The processor is electrically connected and communicated with the controller, the display and the data recording management module.
