Embodiment Construction

[0015] Such as figure 1 The real-time monitoring system for information on the occurrence of storage pests of the present invention is shown. The system includes a gas collection chamber 1, a gas reaction chamber 6 and a computer 10. There are several gas collection chambers 1, and several gas collection chambers 1 are scattered in the granary. In the prime monitoring area, the outlet of each gas collection chamber 1 is collected through the gas flow conduit 3 and then connected to the input end of the micropump 7. A filter screen 2 is sealed at the outlet of each gas collection chamber 1, so that various gases can pass through the filter screen 2 and then enter the airflow duct 3, while impurities such as wheat grains and dust are blocked outside, thereby ensuring The gas in the gas flow conduit 3 runs smoothly. The output end of the micropump 7 is connected to the gas reaction chamber 6 through the gas flow conduit 3, and the olfactory visualization sensor and the camera 8 ...

Abstract

The invention discloses a method and a system for monitoring grain stored-grain insect generation information in real time. A plurality of gas collection chambers are placed in a pheromone monitoring area of a barn in a scattered mode, an olfaction visualization sensor and a camera are fixedly arranged in an inner cavity of a gas reaction chamber, the content and the concentration of the pheromone diffused by female insects are determined through conventional experiential knowledge, and a sensitive color-sensitive material is selected for manufacturing the olfaction visualization sensor; color change values are obtained by subtracting read, green and blue (RGB) pixel values in clear air from RGB pixel values of changed color information; when the change values exceed a preset threshold value, each change value is transformed into a corresponding signal value to obtain a signal response characteristic matrix, and a main content characteristic vector and the determined pheromone content and concentration are selected to establish a partial least square regression model; and when the insect pheromone is measured in real time, the concentration value of the insect pheromone can be obtained according to the model, so that the main insect generation information in the barn can be found out outside the barn, and a suitable control opportunity is selected.

Description

technical field [0001] The invention relates to a monitoring technology for pests in grain storage, in particular to a method and a system for monitoring the occurrence of pheromones of pests using olfactory visualization technology. Background technique [0002] Grain purchases generally coincide with the high temperature period in summer, which is the period when pests are most likely to develop. Therefore, newly entered grains generally carry pests, especially hidden pests. The number of pests in the initial stage of grain storage is small, and the damage is not great, but after a certain period of time, the population of pests will multiply and develop rapidly (according to the logistic formula), and the corresponding amount of damage will also increase sharply. In the central part of China, under suitable conditions, the weight loss of grains stored for three months without any pest control measures can reach 11.25%, and it can reach 35.12% for six months. For grains t...
