| 摘要: |
| 单总线是一些传感器和低速器件与主机通信常用一种总线协议，如智能温度传感器DS18B20，A/D转换芯片等。随着物联网的发展，这些传感器的应用将越来越广泛，而这些接口没有与内核紧密联系，内核无法进行统一管理，稳定性和可靠性无法得到保证。在符合Linux内核设备模型[2]的前提下，实现一个稳定的单总线接口，将整个控制器分为顶层设备接口、核心层、底层硬件接口由上到下三个部分；同时对驱动和设备分离、顶层设备接口和具体硬件操作分离。 |

| Abstract: |
| 1-Wire Bus is a bus protocol which connects some sensors and low-speed devices with the host , such as the smart temperature sensor DS18B20, A/D chip, and so on . With the development of the internet of things , the application of these sensors will become more widespread, but their interface are not closely linked with the kernel , the kernel can not unifiy the management , so stability and reliability may not be guaranteed . In line with the premise of the Linux kernel device model , a stable 1-Wire interface is given . the controller will be divided into three parts, top-level device interface , the core layer and the underlying hardware interface ; while separate the driver and the device, the top-level device interface and the specific hardware operations.
