| The quick development of Internet's hardware and software makes the Internet user increases expeditiously .When we make the network connect with computer, the date acquisition and control appliance are gradually stepping into the net in the production of industry. Now the agriculture and poultry of china are beginning to set foot in this area.The paper takes milk hall as the monitor center, developing microcomputer monitor terminal, RFID wireless information acquisition terminal, weighting and ungroup terminal and data bus gather processor model in which it forms a system communication thread with consecutive communication data bus and takes TCP/IP as data communication protocol layer. Then it works with uplink pc server software to finish the autonomous milking control. At the same time, it also has the monitor and management come true.This data communication system integrates the software and hardware, referring to the TCP/IP, 485 serial bus, RS-232, I2C communication protocol, analog consecutive data communication, RF wireless communication technology, intelligent data collection and equivalent.The paper makes the case that it is not only getting to the require of communication technology but also saving the money. Facing the actuality of the milk occupation in our country, it will be an inevitable development trend and requirement to bring the electronic autonomous and intelligence to the production of agriculture and poultry. |
