【摘要】：随着现场总线技术的不断扩展壮大,越来越多的用户将现场总线应用到铁路交通中,正一步步的实现列车控制系统的网络化、先进化与讯息化。WorldFip总线具有可靠性好、可延伸性强、‘及时性高等优点已被大范围使用,现如今成为许多重载机车、地铁列车等轨道车辆的骨干网。作为目前流行的总线之一的CAN,与其它应用的总线比较,具有高实时性、纠错校验效能以及低成本,因此CAN总线应用在许多的车载电气设备中,如：制动、牵引、车钩、空调等,同时也应用在旅客信息控制等次系统中。为解决重载机车、地铁列车等轨道车辆FIP网络控制系统与带有CAN接口的车载电气设备(如牵引控制单元、制动控制单元等)的互联互通问题,本文设计了一套WorldFip-CAN网关设备,用于WorldFip总线与CAN总线之间的互相连接,实现WorldFip网络和CAN网络之间的双向数据转换功能,WorldFip部分含有WorldFip网络站点的所有通信功能,CAN部分使用规范CAN接口。本文从现场总线技术在近年来的发展状况出发,简单概述了WorldFip总线、CAN总线及WorldFip-CAN网关的发展状况,主要解析了WorldFip和CAN的通信规范。文中以某重载机车FIP测试平台项目为依托,重点设计了WorldFip-CAN网关的三个方面：硬件设计、软件设计和网关调试及型式试验。硬件方面分析了网关设备的架构及可靠性设计、CPU板卡、FIP网卡、电源板卡、母板等板卡的关键电路设计；软件方面主要完成CPU板卡的操作系统移植、CAN和FIP驱动设计以及对应的应用程序编写；并结合FIP网络测试平台对网关进行调试及实验室型式试验,通过测试结果分析表明该网关可实时、可靠的进行CAN网络与WorldFip网络之间通讯数据的转发。该设备的研发为推动我国基于WorldFip网络的轨道车辆等车载电气部件国产化发展提供了有力支持,同时使带有CAN接口的车载电气设备上车使用成为现实。
[Abstract]:With the continuous expansion of fieldbus technology, more and more users are applying fieldbus to railway traffic. The network of train control system is being realized step by step, and the advanced and informational .WorldFip bus has good reliability. The advantages of high extensibility, high timeliness and so on have been widely used. Nowadays, it has become the backbone network of many heavy haul locomotives, subway trains and other rail vehicles. As one of the popular bus, compared with other bus, CAN has high real-time, error correction efficiency and low cost. Therefore, CAN bus is used in many on-board electrical equipment, such as braking, traction, coupler, air conditioning, etc. At the same time, it is also used in the passenger information control system. In order to solve the problem of interconnection between FIP network control system of heavy haul locomotive, subway train and onboard electrical equipment with CAN interface (such as traction control unit, brake control unit, etc.), a set of WorldFip-CAN gateway equipment is designed in this paper. For the connection between WorldFip bus and CAN bus, the bi-directional data conversion function between WorldFip network and CAN network is realized. The part of WorldFip contains all the communication functions of WorldFip network station and can part uses the standard CAN interface. Starting from the development of fieldbus technology in recent years, this paper briefly summarizes the development of can bus and WorldFip-CAN gateway based on WorldFip bus, and mainly analyzes the communication specification between WorldFip and CAN. Based on the FIP test platform of a heavy-haul locomotive, three aspects of WorldFip-CAN gateway are designed: hardware design, software design, gateway debugging and type test. The structure and Reliability Design of Gateway equipment; the key circuit design of CPU board card FIP network card, power card, motherboard and so on; In the aspect of software, it mainly completes the design of can and FIP driver and the corresponding application program of CPU card, and combines with the FIP network test platform to debug the gateway and test the type of the laboratory. The test results show that the gateway can transmit the communication data between CAN network and WorldFip network in real time and reliably. The research and development of this equipment has provided strong support for the domestic development of on-board electrical components such as rail vehicles based on WorldFip network in our country. At the same time, the on-board electric equipment with CAN interface has become a reality.
