Abstract

The invention discloses an odor-based portable insect pest information detecting system which comprises an insect and plant mixed odor acquiring and controlling system, a signal conditioning unit, a data acquisition card and a computer, wherein the mixed odor acquiring and controlling system is connected with the data acquisition card through the signal conditioning unit; and the data acquisition card is respectively electrically connected with the computer and a first electromagnetic valve, a second electromagnetic valve and a gas pump in the insect and plant mixed odor acquiring and controlling system. When the system works, the computer opens the gas pump to pump the insect and plant mixed odor into a sensor reaction chamber, after a gas-sensitive sensor array converts the odor into an electrical signal, the data acquisition card transmits the electrical signal to the computer to analyze, process and judge the insect pest condition, and after the acquisition time, fresh air is introduced to remove odor molecules adsorbed on the gas-sensitive sensor array so as to be convenient for acquisition next time. The invention can discover the insect pest condition of plants in time and can acquire and analyze odors of different insects by changing the sensors in the gas-sensitive sensor array.

Description

technical field [0001] The invention relates to a crop pest information detection instrument, in particular to a scent-based portable pest information detection system. Background technique [0002] Crop pests are obstacles to the sustainable, stable and healthy development of China's agriculture. Every year, there are outbreaks and epidemics of several major pests, which lead to large-scale production reduction and loss of crops, and a decline in quality. To further reduce the losses caused by various pests, the key lies in the accuracy of crop pest forecasts and the ability to report to the police in the early stage of pests, and to take corresponding measures to prevent the further development of pests, preferably to eliminate them in the bud. Insects will produce volatile substances during their life activities, and plants will also produce volatile substances when they are attacked by insects, and these volatile substances are enough to make the gas sensor have a signi...
