There are various means to realize the communication link between FMU and ammeters, such as Ethernet and PLC, however they all have different limitation. We would take advantage of radio frequency in ISM channel to provide a better solution in the communication between FMU and ammeters.

集中器与电表之间的物理链路可以有很多选择，如以太网，电力载波线等，但它们都存在着一定的缺陷，所以我们采用了公用ISM频段的无线通信方式来实现集中器与电表之间的数据通信和采集，这种技术有很多优点，它无需布线、成本低、传输速度快、可靠性高。

ETHERNET: un est á ndar para redes de ordenadores muy utilizado por su aceptable velocidad y bajo coste.

以太网：一种因为可以接受的速度和较低的耗能而非常有用的电脑网络标准。

10Gigabit Ethernet (10 GBASE-R and 10 GBASE-W) uses 64B/66B coding and decoding, which is the code format transform without the high transition density and its redundancy is small at the cost of complicated synchronization and the storage. Thus scramble is added to the 64B/66B and descramble is otherwise added before the 64B/66B decode.

它的10 GBASE-R和10 GBASE-W标准中物理编码层采用了64B/66B编解码方案。64B/66B码只是一种码的格式转换，并没有显著增加码的0、1转换密度。64B/66B编解码方案包括64B/66B码格式转换、扰码/解扰以及数据速率转换。64B/66B码冗余度很小，其代价是同步所需时间和资源相对较多。

According to the calibration information, Research and development status of automotive bus network and automotive calibration system is studied and the research significance is generalized. First of all, the collectivity precept for calibration system is designed, the calibration platform is set up based on the XCP Protocol and the calibration object is CAN bus network simulation ECUs. Then how to create the calibration system based on Ethernet and Series communication is expatiated, the communication way from computer to ECUs is introduced and the calibration system is tested. Then how to create the calibration system based on CAN bus communication is expatiated, the design and the interface programme are introduced and the calibration system is tested. At last the platform is used to calibrate the CAN bus network simulation system to regulate the simulation system's topology and communication speed to test the communication protocol's feasibility.

论文首先设计了标定系统的总体方案，以CAN总线实时仿真系统中的节点标定为研究对象，采用XCP协议建立具有串口、以太网和CAN总线三种通讯接口的标定平台；然后，具体开发了基于以太网通讯和基于串口通讯的标定系统，完成了上、下位机部分的软件设计，确定了标定系统在两种通讯方式下的数据处理方法，并分别应用两种标定方式标定下位机仿真系统的参数，让下位机仿真系统在规定的通讯协议和拓扑结构下进行仿真，对所设计的标定系统进行了调试；接着，设计了基于CAN总线通讯的标定系统，完成了CCP协议（&XCP on CAN&）的接口程序设计，并通过混合动力汽车一种拓扑结构的通讯仿真对所设计的系统进行了调试；最后，应用开发的标定系统，对混合动力电动汽车网络通讯协议进行了仿真研究，并根据实验结果进行了分析。
