| China is a big country pig industry, but because of animal epidemic prevention is not qualified, the management of farming without scale, feeding methods are not correct and o ther reasons, causes the pig production to be reduced, the pork quality drops. Therefore, how to use modern farming techniques to improve the yield and quality of pork are needed to solve the problem. The rapid development of the technology of the Internet of things is the third revolution of the following the computer and the Internet of information technology in the world. Its ultimate goal is to make all the objects are linked with the network, which can real-time identification of any object, monitoring and traceability. The Internet of things technical is cited to the breeding sows, not only can realize real-time monitoring and management of sows, but also can improve the breeding environment, sow scientific farming, to further improve the production, e nhance quality of pork. Therefore, it is of great significance to use the Internet of things technology to research the system of feeding management of pregnant sows.In this paper, the research on the management of the restriction of the pregnant sows bas ed on the Internet of things technology is studied, the independent research and development of a stable performance of pregnant sows limited feeding management system. The system can identify the sow individual information, accurate access to sow weight a nd control the amount of feeding and feeding time, to realize intelligent and limited feeding of pregnant sows. The main works of this thesis are as follows:(1) Design the whole structure of the limited feeding system. On the domestic and foreign research status and things such as Internet of things technology in-depth study, analysis the structure characteristics and working principle of radio frequency identification, sensor, communication technology, introduced the application of Internet of things tech nology in aquaculture. The overall structure of the limited feeding system and the design of each function module were designed, and the overall design scheme was determined.(2) Design and implement the hardware part of limited feeding system. Separately from the main processing module, the radio frequency identification module, the weighing sensor module, the control module and the data transmission module of the system hardware design and implementation of the detailed design. Analysis and selection of t he 89C54 RD STC type microcontroller, 13.5KHZ RF chip and electronic ear standard, square S type pressure sensor and transmitter, 86 type hybrid stepper motor and the corresponding drive. Using keil software programming achieve the function of each module and data transmission, and through the construction of the test system to verify the realization of the hardware part of the system.(3) Designing and development of the limited feeding system software. The overall analysis and design of the software for the limited feeding system, using Eclipse software, Java language system software.To achieve user information management, user rights settings, basic information management of sows, sow production management, feed management, data analysis, data backup, set system parameters and other functions.(4) Designing of the experiment for the limited feeding system.Put forward experimental designs and experiment analysis method, to facilitates the analysis of gestation sows in food intake and eating time with its litter survival rate between the correlation.In summary, in this paper, the development of the Internet of things based on the restriction of the pregnant sows feeding management system to achieve the recognition of sow, weight measurement, automatic control feeding, limit slow feeding and other functions. It has the characteristics of low price, stable performance and so on. It is helpful to intekkigent scientific feeding of pregnant sows, and it has the research significance and application value to the scientific feeding of pregnant sows. |
