基于CH376的高铁电缆温度检测系统设计

On Temperature Detection System Design of High Speed Railway Cable Based on CH376

在我国高铁飞速的发展过程中时常发生意外事故,这些事故大多出自高铁电缆在高负荷运作下电缆温度升高,导致电缆绝缘性能降低,尤其是电缆接头、电缆排列密集的地方,因此对电缆接头温度的检测显得尤为重要.就成都地区独特的地形和排线走势分析设计高铁电缆温度检测系统,考虑到地形、排线成本、工程实施等多方面的原因排除实时检测的设计,而采用本地存储的方式.通过IAP15W4K61S4主控芯片,DS18B20数字温度传感器和CH376U盘管理芯片搭建测温系统,将采集到的温度值实时存入U盘中,相对于目前的测温方式有了非常大的改善.该系统独立存在,成本低、体积小、抗干扰能力强、易于安装,能够很好地实现测温,为电力电缆测温系统的研究提供了一个新的方向.

China witnesses a rapid growth in its high-speed railway construction in the past few years.The development also brings some accidents caused mainly by excessive time and high load operating of highspeed railway cables,especially in cable connectors and cable-intensive places.It is,therefore,vital to detect the temperature of high-speed railway cables.In this paper,in consideration of the unique topography,cable costs,project implementation,etc.,a temperature detection system with local-storage has been designed for high-speed railway cables.The proposed system consists of IAP15W4K61S4 as main control chip,DS18B20 as digital temperature sensor and CH376 as U disc management chip.The system collects temperature record and store it in U disk,which proves to be an impressive improvement on the existing systems.This system can detect cable temperature accurately with advantages of independent operation,low cost,small size,and strong anti-interference ability.In addition,the proposed temperature detection system provides a new direction to power electronics research.
