A measurement method for liquid medicine superficial deposit homogeneity based on the measurement system is also provided; the fogdrop deposition inductive sensor based on dielectric constant variable capacitor is used for combining the sensor node device to the Ad-hoc network wireless sensor network for automatically collecting the liquid medicine fogdrop deposition amount in the spraying region at real time, the computer executes the statistic analysis on the fogdrop deposition amount to obtain the evaluation of the fogdrop deposition homogeneity of the spraying region, the analysis complexity for the fogdrop settling character for aviation drug delivery can be effectively reduced and the efficiency of the measurement method is raised.

Description

technical field [0001] The invention relates to the technical field of aerial drug application, in particular to a method and system for measuring the uniformity of drug liquid ground deposition. Background technique [0002] In aerial pesticide application, the uniformity of ground deposition of chemical solution is an important index for evaluating the effect of aerial pesticide application. At present, the means of obtaining the ground deposition characteristics of aerial pesticide spray droplets mainly use the method of laying water-sensitive paper on the ground to sample the deposited droplets, and then use the image processing method to obtain the droplet coverage and droplet size distribution of the sampling points , and then indirectly calculate the coverage rate of the spraying area, and then evaluate the uniformity. [0003] The specific implementation steps of using the water-sensitive paper method to analyze the characteristics of ground deposition are: install ...

AI Technical Summary

Problems solved by technology

It can be seen that from the completion of spraying to the uniformity data, the time lag is relatively large, and many manual operations are required in the middle

[0005] 2. The experimental materials cannot be reused, and the water-sensitive test paper needs to be replaced every time the pesticide is applied.

[0006] 3. Lack of control over the deposition process of droplets

It is not difficult to see that the method of using water-sensitive test paper can only obtain the deposition amount after the deposition is completely completed, and cannot realize the description of different time periods in the deposition process

[0007] 4. The experimental process is cumbersome, takes up a lot of manpower and time, and is poor in convenience

After the experiment is completed, collect the water-sensitive paper, scan the image of the water-sensitive paper one by one, and analyze it. The process is cumbersome and requires the cooperation of multiple people.

[0008] 5. The operation requirements are high, and data errors caused by misoperation are inevitable

Because water-sensitive paper is extremely sensitive to water and oil, it is necessary to wear rubber gloves during the experiment. A little carelessness will leave marks on the water-sensitive paper, which will directly affect the experimental data
