Description
Technical field
The utility model relates to a kind of material tower weighing-appliance more particularly to a kind of remote sensing type material tower weighing-appliances.
Background technique
With the improvement of the national economy, China Meat consumption proportion improves year by year, livestock-raising also from casual household cultivate towards
Large-scale cultivation transformation, automation and intelligent pig raising equipment will be widely applied in big-and-middle scale pig farm.Feed link
Cost accounting during pig-breeding has been more than 60%, and the requirement for feed fine-grained management is also higher and higher.Expecting tower is
Main feed memory space in farm.Therefore, there is an urgent need to the prisons that one kind can detect feed tower storehouse residue doses automatically
Control system.
The monitoring method in traditional feed tower storehouse is all mainly manually to check.Feed tower storehouse be translucent material,
By visually checking remaining doses.Some feed tower storehouse translucency are bad, can not by visually checking remaining doses, need using
Hand taps it, and remaining doses is distinguished by sound.Inspection personnel is recorded on paper after inspection, is reporting to other
Department.In recent years, fraction material tower begins to use the material tower weighing-appliance of ground list formula.Current material tower weighing passes through installation weighbridge,
By the weighing of electromechanical, to measure material tower gross weight, to obtain the remaining doses in material tower.
The check process in feed tower storehouse have naked eyes check, verify, recording sheet shelves and report 4 links of higher level department.In meat
Eye, which is checked, can not accurately calculate remaining doses, not accomplish the fine-grained management of demand.Link is recorded in paper shelves, due to the work of personnel
Make fault problem, causes the content of recording sheet shelves wrong.It needs to give higher level department in report after record, will cause data update
Delay.
Although expecting that the method for installing traditional weighbridge below tower can accomplish the management of fining, equipment cost height, base
It builds at high cost, does not meet the cost requirement of farm.Secondly, weighbridge undertakes the weight bearing of entire material tower, so weighbridge is easy to damage

When a part of old material tower can not install the equipment additional.Finally, weight bridge weighing can only measure gross weight, moisture is total in indistinguishable feed
Proportion in weight.
To sum up, traditional material tower weighing technology can not meet this timely, accurate, inexpensive triple standard simultaneously.Therefore, expect
Tower weighing technology is not wide in farm's use.Subjective experience can only be passed through due to lacking the accurately surplus material data of material tower, farm
Judged, it is thus possible to will appear the defect in terms of the feed managements such as stock deficiency, feeding excess.On the other hand, feed number
According to related to the cultivation such as feedstuff-meat ratio critical data.Accurately expect the surplus material data of tower due to lacking high frequency, farm can not whole process chase after
Track feedstuff-meat ratio information.In the case where loss of learning, novel fodder research and development fall into stagnation, and an empty verbiage is become in fining cultivation.

Pixel, if the nonqualifying pixels points distance of each column is greater than m pixel, it is considered that the Lieque is lost, otherwise it is assumed that the column
Qualification, and record the average value of all nonqualifying pixels point row coordinates of the columnp, after steering engine 6 traverses all angles, can choose certain
A specific angleα, the angleαMeet two following conditions: qualification column at most, and respectively arrangepIt is worth consecutive variations；Qualification columnpValue
Average valueMinimum, levels off to 0；Under the conditions of the two, illustrate that CCD camera 5 captures a clearly laser line projection,
And the laser rays is located in the middle part of image；Using triangle telemetry, triangle remote sensing distance is obtained by following formulaR2’:
Wherein,,,LBe linear laser source 2 and CCD camera 5 it
Between horizontal distance,FIt is the stationary lens focal length of CCD camera 5；
T shape mounting rack 1 is in the corresponding all distances in all positionsR2’It carries out average computation and obtains final average departure
From；
The characteristics of range of triangle is strong antijamming capability, but time of measuring is long, and certain times may be because masking failure；
Alternately started using pulse ranging or range of triangle or two kinds of distance measuring methods, and uses Kalman Filtering and decision tree
Equal usual manners turn inward between charge level 16 and linear laser source 2 to obtain continuous, the accurate i.e. material tower 13 of comprehensive remote sensing distance
Comprehensive distanceR’；
Step (7.3): measurement clout weight:
It is calculated by the following formula the weight of clout in material tower:
Wherein,,VBe in material tower bottom to the overall volume between the luminous point of linear laser source,S
It is the sectional area for expecting midsection.
Above-described embodiment is the preferred embodiment of the utility model, is not the limit to technical solutions of the utility model
System, as long as being regarded as falling into without the technical solution that creative work can be realized on the basis of the above embodiments
In the rights protection scope of the utility model patent.
