Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, system of the present utility model comprises CCD camera 1, support 2, framework 3, support bar 4, Web materials 5, pressure transducer 6 and computer 7; CCD camera 1 is connected to directly over framework 3 by support 2, and be connected to computer 7, framework 3 lays Web materials 5 above, support bar 4 is provided with for reducing the elasticity of Web materials 5 in the middle of framework 3, the corner intrinsic pressure transducer 6 for measuring chicken body weight respectively below framework 3, each pressure transducer 6 is connected with computer respectively by A/D converter, the unlatching of computer 7 control system, runs image processing program, stores weight data.
Support 2 is welded on one side of framework 3, and support 2 material is steel pipe, lays CCD camera 1 circuit in steel pipe.
Framework 3 material is U-steel, by welding, U-steel is connected into a square frame.
Support bar 4 is welded between framework 3, and material is U-steel, plays a supportive role.
Web materials 5 material is steel wire, forms woven wire by welding.
The method that the utility model is weighed comprises:
Build a weighing platform, this platform is made up of framework, support bar and Web materials, and CCD camera is fixed on above weighing platform by support, and below weighing platform, Corner Strapped has the pressure transducer measuring chicken body weight, pressure transducer is fixed on farming site ground, and during unlatching, pressure resets.When measuring the chicken body weight sum variation obtained and being less than certain threshold value, trigger the image that CCD camera obtains weighing platform region, obtain the quantity of chicken on weighing platform through image procossing.According to chicken quantity on TBW and platform, calculate the average weight of chicken.During cultivation, set time section is opened, and can obtain the average weight of chicken every day, thus draws body weight growth curve.
As shown in Figure 2, setting triggers the threshold k of camera work, the pressure data that t receives and be P
t, the pressure data that the t+1 moment accepts and be P
t+1, when measuring the chicken body weight sum variation obtained and being less than certain threshold value, namely | P
t-P
