基于FX_(2N)-4AD-PT的高速动车组轴温检测系统

High Speed Bullet Trainsaxle Temperature Detecting System based on FX_(2N)-4AD-PT

结合陕西省教育厅创建示范专业建设需求,为了加强专业课程教学的实践性和多门课程知识的综合应用,基于FX_(2N)系列PLC设计了一种高速动车轴温检测系统。依据高速铁路实际轴温检测要求,提出测温系统的基本功能,设计了具有温度显示、声光预警报警功能的硬件电路。分析了FX_(2N)-4ADPT的性能指标、缓存器分配及读写指令,将FX_(2N)-4AD-PT应用于高速动车轴温检测系统,简化了系统电路设计。依据系统功能需求,结合硬件电路,编写了高速动车轴温检测程序,系统的预警、报警温度均可通过程序设置。系统功能、指标完全能满足教学需求。

In order to meet the requirement of specialty construction by Shaanxi department of education, we design a lo comotive temperature detection system based on FX2N system PLC to strengthen practical teaching and synthesis application of knowledge. According to the requirements of high speed train temperature detection, we develop the basic function of de- tection system, and design hardware circuit with the function of temperature readings and sound light alarm. We analyze the performance index of FX2N-4AD-PT, cache allocation and read-write operations, then apply the FX2N-4AD-PT to the system of locomotive temperature detection and simplify the circuits . In addition, we write temperature detection programs which have the function of early warning and temperature reading. The function and performance index of the system fully satisfy the teaching requirement.
