The Design and Realization of Digital Community Information Issuing System Ma Shi-xia, Li Ji-biao Dan, Zhai Hai-qing,Liu Dan (1.Henan Mechanic and Electric Engineering College, Xinxiang Henan 453002;2.Zhengzhou University, ZhouZheng Henan,450001) Abstract: Using CAN bus and the C++ technology to develop digital community information issuing system, the paper introduces the software and hardware structure of CAN field bus communication system, and elaborates the data exchange principle, then discusses several important problems and design thought in the design. The digital community communication network based on the CAN bus realizes the community information dynamic management, and overcomes the static state management’s flaw .The form causes the information issuing promptly and effectively, then enhances the working efficiency.
