目前,智能监控已成为一种趋势并深入到我们生活的各个层面,在我们生活的各种场合都有智能监控的影子。智能监控的深入也对其要求在不断地提高,可视化、灵活、稳定可靠、操作方便等都成为考核和验证一个系统能否占领市场的性能指标。无论是家用电器、智能楼宇还是工业类产品都要求具有人性化操作的功能,显示屏、键盘等用户界面和实时可靠的控制已成为产品不可或缺的部分。要保证系统各部分可靠运行、又要保障给用户提供良好的操作界面,将显示、各个关键控制部分等分别由不同的控制单元来完成,而各个控制单元之间则通过总线的通信方式完成数据和信息的交换已成为构建系统的一种方式。本文针对控制单元之间如何通信进行了探讨,对几种通信方式进行对比并给出其实现的途径。
At present, intelligent monitoring has become a trend and deepens to all levels of our life, with the shadow of intelligent monitoring on various occasions of our life. Intelligent monitoring of its requirements are constantly improving, visualization, flexibility, stability, ease of operation and so have become a test and verify a system can dominate the market performance indicators. Whether it is household appliances, intelligent buildings or industrial products require a user-friendly features, display screens, keyboards and other user interface and real-time and reliable control has become an integral part of the product. To ensure the reliable operation of various parts of the system, but also to provide users with a good user interface will be displayed, the various key control sections were completed by the different control unit, and each control unit through the bus communication to complete the data The exchange of information has become a way of building a system. This article discusses how to control the communication between the units were discussed, the comparison of several communication methods and gives its way to achieve.
