[0002] Comprehensive monitoring of the internal storage environment of grain is the key to ensuring long-term safe storage of grain. Currently, grain storage mainly relies on large granaries. The storage environment in the granary, such as temperature, humidity and gas concentration, has an important impact on the storage of grain. If the storage environment is not properly controlled, the storage time of grain in the granary will be shortened, causing the grain to become damp, moldy, and have quality problems.

[0003] At the same time, pest problems are also an important factor affecting the grain storage process. Pests that breed in the granary will eat and contaminate the grain, causing losses in grain storage. Therefore, it is necessary to monitor and control the granary environment in real time to detect various problems in the granary in time to avoid causing greater losses.

[0004] At present, environmental monitoring of granaries mainly focuses on the monitoring of storage environments such as temperature, humidity, and gas environment, which is often separated from the monitoring of granary pests. In addition, the monitoring of granary pests is mostly based on the attraction of biological agents, trapping with fans, etc. The required equipment is complex and not easy to integrate.

The light-attracting module includes an LED light source, a coupler and a through-light emitting optical fiber which are electrically connected in sequence. The LED light source is electrically connected to the control unit. The LED light source is controlled by the control unit to emit light of different specific wavelengths. Light of different specific wavelengths corresponds to different colors, which has a strong attraction to various pests in the granary, thereby playing a role in luring pests. The coupler is used to efficiently couple the light of a specific wavelength emitted by the LED light source into the through-light emitting optical fiber to reduce light loss. As a special optical fiber, the through-light emitting optical fiber can emit light along its entire length to form a light strip that attracts pests. A transparent encapsulation shell is arranged outside the through-light emitting optical fiber. The arrangement of the transparent encapsulation shell can protect the internal through-light emitting optical fiber from external extrusion and dust pollution that affects the luminous effect. Secondly, as a carrier for the through-light emitting optical fiber to penetrate into the granary, a variety of sensors can be arranged to monitor the environment inside the granary.

The monitoring module includes a macro camera, a temperature sensor, a humidity sensor, an oxygen sensor and a nitrogen sensor, wherein the macro camera is used to collect images inside the granary, take real-time photos of the granary pests lured to the outside of the transparent packaging shell, and transmit the acquired image information to the control unit. The macro camera is set on the inner wall of the transparent packaging shell, and one or more macro cameras are set to ensure all-round coverage of the monitoring. In the utility model, the temperature sensor is used to monitor the real-time temperature inside the granary and transmit the real-time temperature data to the control unit; the humidity sensor is used to monitor the real-time humidity inside the granary and transmit the real-time humidity data to the control unit; the oxygen sensor is used to monitor the oxygen concentration inside the granary in real time, and the nitrogen sensor is used to monitor the nitrogen concentration inside the granary in real time. The temperature sensor, humidity sensor, oxygen sensor and nitrogen sensor are all integrated in a transparent packaging shell. A plurality of ventilation holes are arranged on the shell of the transparent packaging shell, and a breathable sheet is arranged on the ventilation holes to ensure that the gas in the transparent packaging shell interacts with the gas environment in the external granary, thereby ensuring the accuracy of the measured gas concentration and temperature and humidity data. The integration of different sensors can reduce the number of equipment in the granary and simplify installation and maintenance work. At the same time, in this embodiment, a plurality of transparent packaging shells with integrated multiple sensors are arranged, which are evenly distributed in the granary to ensure the accuracy of the monitoring results.
