Page 10 LOCAL INTERCONNECT NETWORH 1.LIN LIN Local Interconnect Network) is a concept for low cost automotive networks, which complements the existing portfolio of automotive multiplex networks. LIN will be the enabling factor for the implementation of a hierarchical vehicle network in order to gain further quality enhancement and cost reduction of vehicles. The standardization will reduce the manifold of existing low-end multiplex solutions and will cut the cost of development, production, service, and logistics in vehicle electronics 1.1.1 SCOPE The Lin standard includes the specification of the transmission protocol, the transmis sion medium, the interface between development tools, and the interfaces for soft- ware programming. LIN promotes the interoperability of network nodes from the viewpoint of hardware and software and a predictable Emc behavior 1.1.2 FEATURES AND POSSIBILITIES The LiN is a serial communications protocol which efficiently supports the control of mechatronics nodes in distributed automotive applications The main properties of the lin bus are single master with multiple slaves concept low cost silicon implementation based on common UART/SCI interface hardware, an equivalent in software or as pure state machine self synchronization without a quartz or ceramics resonator in the slave nodes deterministic signal transmission with signal propagation time computable in advance low cost single-Wire implementation speed up to 20 kbit/s signal based application interaction predictable behavior reconfigurability transport layer and diagnostic support The intention of this specification is to achieve compatibility with any two LIN imple mentations with respect to the scope of the standard, i. e from the application inter- face, APl, all the way down to the physical layer Websitewww.lin-subbus.org 【实例截图】

Page 10 LOCAL INTERCONNECT NETWORH 1.LIN LIN Local Interconnect Network) is a concept for low cost automotive networks, which complements the existing portfolio of automotive multiplex networks. LIN will be the enabling factor for the implementation of a hierarchical vehicle network in order to gain further quality enhancement and cost reduction of vehicles. The standardization will reduce the manifold of existing low-end multiplex solutions and will cut the cost of development, production, service, and logistics in vehicle electronics 1.1.1 SCOPE The Lin standard includes the specification of the transmission protocol, the transmis sion medium, the interface between development tools, and the interfaces for soft- ware programming. LIN promotes the interoperability of network nodes from the viewpoint of hardware and software and a predictable Emc behavior 1.1.2 FEATURES AND POSSIBILITIES The LiN is a serial communications protocol which efficiently supports the control of mechatronics nodes in distributed automotive applications The main properties of the lin bus are single master with multiple slaves concept low cost silicon implementation based on common UART/SCI interface hardware, an equivalent in software or as pure state machine self synchronization without a quartz or ceramics resonator in the slave nodes deterministic signal transmission with signal propagation time computable in advance low cost single-Wire implementation speed up to 20 kbit/s signal based application interaction predictable behavior reconfigurability transport layer and diagnostic support The intention of this specification is to achieve compatibility with any two LIN imple mentations with respect to the scope of the standard, i. e from the application inter- face, APl, all the way down to the physical layer Websitewww.lin-subbus.org 【实例截图】

小贴士
感谢您为本站写下的评论，您的评论对其它用户来说具有重要的参考价值，所以请认真填写。
- 类似“顶”、“沙发”之类没有营养的文字，对勤劳贡献的楼主来说是令人沮丧的反馈信息。
- 相信您也不想看到一排文字/表情墙，所以请不要反馈意义不大的重复字符，也请尽量不要纯表情的回复。
- 提问之前请再仔细看一遍楼主的说明，或许是您遗漏了。
- 请勿到处挖坑绊人、招贴广告。既占空间让人厌烦，又没人会搭理，于人于己都无利。
