摘 要：【目的】中冷控制器涵盖多种科学技术，具有一定的开发难度。【方法】课题组基于Profibus-DP总线接口，结合现代电子/电气设计方法和EMC工程设计实务，采用电路的模块化方法，设计了四种中冷控制器模块方案，从电机伺服驱动、温度测量、编码器脉冲计数、Profibus-DP总线四个方面分析了中冷控制器接口设计及算法，提出了部分硬件设计原理图以及温度控制算法及编程，并进行了发动机转速分别为1 400 rpm、1 800 rpm和2 000 rpm时的涡轮增压后空气温升、压降、扭矩降实验。【结果】在不同运转工况下，发动机温升速度均不相同，功率越大、负荷越高，则温升速率越快；随着温度升高，涡轮增压的空气压力反而下降；随着涡轮增压后空气的温升，发动机扭矩下降。【结论】通过比较，选用总线桥产品，可以优化电子器件布局、布板布线，大大缩短课题开发时间，提高总线应用的稳定性与可靠性，对于短时间内工业级产品的设计与制造具有很好的应用价值。

Abstract: [Objective] The intercooling controller covers a variety of scientific technologies and has certain development difficulties. [Method] Based on the Profibus-DP bus interface, combined with modern electronic/electrical design methods and EMC engineering design practices, the research group adopted a modular circuit approach to design four intercooling controller module schemes. The interface design and algorithms of the intercooling controller were analyzed from four aspects: motor servo drive, temperature measurement, encoder pulse counting, and Profibus-DP bus. Some hardware design schematic diagrams, temperature control algorithms, and programming were proposed. And conducted air temperature rise, pressure drop, and torque drop experiments after turbocharging at engine speeds of 1 400 rpm, 1 800 rpm, and 2 000 rpm, respectively. [Result] Under different operating conditions, the temperature rise rate of the engine varies. The higher the power and load, the faster the temperature rise rate. As the temperature increases, the air pressure of turbocharging actually decreases. As the air temperature rises after turbocharging, the engine torque decreases. [Conclusion] By comparison, selecting bus bridge products can optimize the layout of electronic devices and board wiring, greatly shorten the development time of the project, improve the stability and reliability of bus applications, and have good application value for the design and manufacturing of industrial grade products in a short period of time.
