摘　　要：针对共轨ECU快速原型平台建立底层硬件函数库的复杂性,采用基于LabVIEW的虚拟仪器技术和NI FPGA技术,从控制层软件功能要求出发,开发了信号输入方式模块、信号处理模块,PWM和开关量输出模块。实现多路传感器信号同步多速率输入以及控制信号输出。将输入输出功能封装成子VI,控制层软件调用此子VI实现对硬件端口的直接操作。同时,集成信号的显示、数据存储及回放功能,为平台的数据监控功能和数据后处理功能提供数据来源。经发动机台架验证,表明开发的功能模块具有运行可靠、功能完善、界面友好的特点,此种开发方法效率高、功能强。The establishment of substratum hardware function library was complicated and difficult in rapid prototyping for common rail diesel engine ECU. The signal input module, signal processing module, PWM and digital output module based on software functional requirements of the control level software using LabVIEW virtual instrument and the NI FPGA technology were developed. Realized multi-sensor and multi-rate input signal synchronization sample and control signal output are presented. The input and output capabilities were packaged into sub VI, the control layer software can operate the hardware port directly by calling sub-VI, overcomes the difficulty development with the text language The real time display, data storage and playback functions were developed, it provided the data sources of the data monitoring and data processing functions. The engine bench-test verifie functional modules are functional, user friendly, and the way is efficient.
