Description
Technical field
The present invention relates to a kind of matrix form liquid collecting cell array liquid collecting amount automatic tour inspection system; Matrix form liquid collecting cell array liquid collecting amount automatic tour inspection system in particular for the test bed collection mist of spraying mechanical mist amount distributing homogeneity amount automatic reading belongs to agricultural engineering test and measuring technical field.
Background technology
Mist amount distributing homogeneity is meant the homogeneity of droplet deposition distribution on target in the spraying mechanical operation process, is the important indicator of weighing the spraying mechanical transaction capabilities.Fast, accurately detecting improving spraying mechanical detection technique level, optimize the spraying mechanical job parameter and improving the spraying mechanical design level of mist amount distributing homogeneity is all significant.
JB/T9782-1999 " the general test method of equipment for plant protection " and JB/T9805.2-1999 " spray boom formula spraying machine test method " regulation can adopt level set mist groove to collect droplet carrying out the test of horizontal mist amount distributing homogeneity, and level set mist well width is not more than 50mm; GB/T24683-2009/ISO 9898:2000 " the plant protection mechanism shrub is used the air-assisted type spraying machine test method with the arbor crop " regulation can adopt vertical mist amount layering gatherer to collect droplet carrying out the test of the vertical mist amount of air-assisted type spraying machine distributing homogeneity, and the branch interlamellar spacing is not more than 250mm.In horizontal mist amount was evenly distributed property testing, test zone was generally 3m * 1m, along the 1m direction collection mist groove was set, and 60 collection mist grooves then need be set at least, and 60 liquid collecting unit need be set accordingly; In vertical mist amount was evenly distributed property testing, the test zone height was generally 4.5m, and 18 layering gatherers then need be set at least, and 18 liquid collecting unit need be set accordingly.Obtain more detailed droplet distributed intelligence, then need reduce droplet and collect spacing, more liquid collecting unit correspondingly need be set.And along with the increasing of liquid collecting unit, more and more loaded down with trivial details, complicated even difficulty that the manual work of liquid collecting amount or automatic reading will become.The distribution that droplet is put at level or vertical target is a kind of Two dimensional Distribution, and the testing method of stipulating in the above-mentioned standard all can only provide the one dimension distributed intelligence of ribbon area dividing, can't reflect the deposition distribution situation of droplet on target comprehensively.If collect droplet and adopt the two-dimensional mesh trellis to divide, though can access comprehensive Two dimensional Distribution information, the liquid collecting unit can increase on corresponding tens of times of ground, and it is unusual loaded down with trivial details and difficult that the manual work of liquid collecting amount or automatic reading will become.The quick pin-point reading of liquid collecting amount has become the crucial restraining factors that mist amount distributing homogeneity measuring accuracy improves.
