| Rice-duck is very good ecological agriculture pattern with make is a kind of ecological, economic and social benefit, especially suitable for production of organic rice. It is very especially suitable for water source protection area in reservoir upstream.Currently affecting the popularization and application of the rice-duck make technical problem is the management of the duck. At present there are two forms, duck for the night is a kind of every evening with manual called ducks from paddy field back to home, integrated feed into the case in the night, poor working conditions and spend large strength.Another way is, in the paddy field juggle building temporary duck, manual feeding part of the feed, the existing simple duck are generally open-style, cannot ensure the security of the duck for the night, weasel, mouse, fox, snakes and other predators will endanger the duck’s life, at the same time also need manual feeding.In this paper, aiming at the existing problem of the original wild duck automation, put forward the improvement scheme.Design of wild wild duck automation realized automatically open the door in the morning and night automatically play music calls up duck, automatic shutdown, automatic feeding, automatic water supply, realized unattended, ensure the safety of the ducks in the field for the night.(1) Key components in the wild duck automation improvement.For the original feed system exists arch feed after be affected with damp be affected with damp easily, the serious influence on the precision of the blanking, the improving design adopts the arch breaker has the feeding system.Arch way adopted vibration breaking arch way.Passed the related tests, feeding motor choose 24 v DC gear motor of 160 w/7.5 r/min.Arch breaker and feeding system, the optimal combination of parameters for the source location is located in below the hopper, vibration motor speed of 1200 r/min, vibration eccentricity of CAM is 30 mm.In the process of container discharge peak torque of 47.79 Nm.Arch breaker motor relative to the feed motor startup sequence in the confidence of α=0.05, has a significant effect on cutting precision.For automatic door driven by image design, the minimum torque of 9.8 N, running speed of 5/min speed is the most appropriate, from 0 to 5 r/min to accelerate the process need time is 0.0067 s.To design the wild duck automation need energy calculation shows that the power of 80 w solar panels, battery capacity required for 50 ah.Through finite element analysis of container load bearing arm, the shape of the container load bearing arm is T structure, material selection of stainless steel.(2) The wild duck automation control system hardware design improvements.On the original control system without working instructions, use, adjust the inconvenience USES STC12C5A60S2 single-chip microcomputer as its control core design of a new type of dry controller.Increased to reflect the status of the wild duck automation work status indicator.(3) The wild duck automatically control system software design improvements.In order to meet the requirements of the duck night drinking water, increased the automatic water supply device, using C language and Keil uVision as MCU development language and development environment, design the combined with digital tube display and graphic display panel control system.(4) The wild duck automation field experiment.By 2015 in liaoyang dengta xinguang village for a period of 36 days paddy field test, the test data analysis results show that the automatic door delay time and summon up the loudness of sound in the confidence of α=0.05, the ducks The returning rate of ducks there is a significant effect.Automatic door 1 min delay time, sound loudness 100 db, ducks The returning rate of ducks can reach more than 97.5%.Through the single factor analysis of variance, the wild duck automation feeding ducks average weight compared with artificial feeding and there is no significant difference.The wild duck automation the failure rate is 3%. |
