基于STM32和CAN总线的楼宇自动化系统设计

摘要

This paper introduces the relevant concepts and design system of building automation. Due to space division,the whole building is divided into a plurality of independent regions,and each one is set in a different system,such as power supply,water supply, fire protection,access control system and so on;each system is set with function detection,control and information transmission,but there is also close contact between them. Based on the consideration of cost and performance,abundant peripherals STM32 series are used to conduct regional control and the use of real-time CAN bus connection of each region make the sharing of multi host control and information control points realized.%介绍了楼宇自动化的相关概念及系统设计。整栋楼宇由于空间的分隔，分为多个独立的区域，而每个相对独立的区域都集合着不同的子系统，如供电、供水、空调、消防、门禁系统等，每种系统集合着检测、控制与信息传递等功能，而且每个独立区域之间还有紧密的联系。基于成本和性能的考虑，采用外设丰富的STM32系列单片机进行区域控制，并采用具有实时性的CAN总线连接每个区域，实现了各测控点的多主机控制与信息共享。
