基于DSP和CAN总线的楼宇对讲系统的设计

The design of intercom-speaking of building system based on DSP and CAN bus

本文主要针对TI公司的DSP芯片TMS320F2812的内嵌ECAN控制器的增强特性,提出了一种基于DSP和CAN总线的楼宇对讲系统的设计方案。该方案重点介绍了CAN总线智能节点的硬件原理和软件设计。系统实际运行表明其设计合理、功能完善、工作可靠性高,现已成为新一代智能居住小区网络建设的趋势。

This paper mainly analyzes the strengthened characteristics of the ECAN controller embedded in TMS320F2812 DSP made by Texas Instruments, and poses a design of the intercom-speaking of building system based on DSP and CAN bus. This design gives a particular description of the hardware theory and the software frame of the intelligent node of CAN bus. It indicates that the design has perfect function and high reliability after actual running ,and it will become the trend of new generation of intelligent residential areas .
