摘要
主要介绍了基于LonWorks总线技术的节点开发工作。结合火灾报警系统的要求 ,分别就系统结构、神经元芯片的I/O对象分配和定义、硬件和软件等方面进行了讨论和分析。开发的现场节点有效解决了自动寻址和火警信息的处理、传输等问题 ,提高了网络灵活扩展的能力和报警的准确率。
The development of the nodes based on LonWorks technology is introduced. Combining with the requirements of fire alarm system, the system structure, I/O object distribution and definition of neuron chip, hardware and software are discussed and analyzed accordingly. The developed nodes resolved the problems of automatic addressing, fire information processing and transmission, flexible expansion of the network and enhancement of alarm accuracy.
