基于CAN总线的直燃式液氮泵车控制系统

摘要

介绍了直燃式液氮泵车的组成和工作原理，设计一种基于CAN总线的液氮泵车控制系统。描述了控制系统与发动机ECU的CAN总线通讯的配置，并重点介绍控制系统中温控器的组成、蒸发器的温度控制原理。%This paper introduces the composition and principle of liquid nitrogen pump truck with direct fired vaporizer, and designed a control system of liquid nitrogen pump based on CAN bus. The paper also describes the configuration of control system and engine’s ECU based CAN bus, and introduces the composition of temperature controller and the temperature control principle of direct fired vaporizer.
