| With the rapid development of society and the improvement of people’s living standard,people pay more and more attention to the safety and health of food,and natural products become hot.As a result,animal husbandry is developing rapidly in order to meet the needs of the times and the market.At the same time,the management of livestock farms has become more difficult.It is difficult to guarantee the accuracy of livestock raising information.In the paper,a visual monitoring system and a safety traceability system are designed,which can be used to monitor scattered livestock with complicated environment at any time.The accuracy of traceability information of meat products can also be guaranteed.The paper first introduces the development environment and selection of the system.B/S and C/S are selected as the architecture of the system.The use of the system development environment and the choice of development technology are also introduced one after another.The importance of the database and other related technologies are expounded.Secondly,according to the needs of the agricultural pasture and the relevant government quality supervision departments,the design scheme of the system is determined,and the economic feasibility of the system is also discussed.Technical feasibility and operational feasibility are analyzed to determine the feasibility of the design and development of the system.Then,the paper divides the visual monitoring and security traceability system into real-time video surveillance,user login,user information management,traceability coding database management,traceability production and aquaculture,traceability of slaughterhouse processing and traceability of transportation.The seven modules are designed separately.According to the functional requirements of each unit part,the module flow chart or function structure diagram of each part of the design is designed in detail.Then the hardware design and software programming are carried out according to the specific design method of each module described above,and finally the function of each module is realized.And the successful realization of each unit function is presented in this paper in the form of specific software interface.Finally,it is necessary to test each functional module.The test results of each method are consistent with the expected results,and meet the needs of agricultural and pasture companies and government departments. |
