车载设备嵌入式监控组态软件的研究与应用

Research and application of vehicle embedded supervisory configuration software

针对传统嵌入式编程方法开发周期长、开发难度大等问题,结合车载嵌入式设备资源有限、实时性要求高等特点,提出了一套完整的车载嵌入式监控组态软件(Vehicular Embedded Supervisory Configuration Software,VESCS)设计方案。重点对其体系结构、图形控件、协议和实时数据库等关键技术进行了介绍;结合车载设备CAN帧特性,将设备变量各属性抽象为结构体变量,引入定序链表和二分查找思想,提出了一种高效的实时数据库设计方法。将VESCS应用于工程机械专用车辆,表明VESCS较传统方法缩短了90%以上开发周期时间,在显著降低开发成本的同时,满足了车载类设备的各类监控需求。

Traditional embedded programming has a long developing cycle and great developing difficulty. Aiming at the characteristics of limited resources and high real-time requirements on vehicular embedded equipment（问题）, this paper proposes a design scheme of Vehicular Embedded Supervisory Configuration Software （VESCS）（过程）. The key technologies including architecture, graphical controls, protocol, and real-time database are focally presented. Combined with the feature of CAN frame for vehicular equipment, the device variable attributes are abstracted into structure vari- ables. The sequencing linked list and the binary search ideology are introduced, and an efficient real-time database is put forward（方法）. The application of VESCS in construction machinery demonstrates that, compared with traditional pro- gramming, VESCS can shorten 90 percent of developing cycle and meet all kinds of requirements of monitoring on ve- hicular equipment with the significant reduction of developing cost.
