The invention discloses a real-time detection apparatus and method for field particle operation parameters. The apparatus comprises a host computer and a plurality of detection nodes; each detection node comprises a concentration detection module and a master control circuit; the master control circuit calculates the particle operation parameters according to data detected by the concentration detection module and sends calculation results to the host computer; and the concentration detection module comprises a light emitting element, a through hole and a light receiving element, wherein the light emitting element emits an optical shaft capable of covering the through hole, and the light receiving element receives scattered light of particles when the particles pass through the through hole, converts an optical signal into an electric signal and sends a processed electric signal to the master control circuit. Since the concentrations of particles entering the through hole are different, light scattering degrees are different, and thus, obtained electric signals are different; and the master control circuit analyzes the signals to obtain current particle operation parameters. The apparatus can be repeatedly used and is capable of precisely detecting field particle operation parameters in real time.
Description
technical field [0001] The invention relates to the technical field of field particle operation parameter detection, in particular to a real-time detection device and method for field particle operation parameters. Background technique [0002] In agricultural activities, field particulate matter operation parameters have a great influence on the operation effect. For example, the amount of droplet deposition during spraying has a direct impact on the efficacy of the drug, and an appropriate amount of droplet deposition can ensure a good effect of the drug. At present, the most widely used method for measuring the amount of spray droplet deposition is the water-sensitive paper method, but the water-sensitive paper method is not real-time, and its use is not repeatable. In addition, there is an image processing method as a relatively new detection method of droplet deposition, but this method has higher requirements for equipment and higher cost. [0003] With the rapid dev...
