摘要
针对动车组客室照明系统的控制原理和测试方法进行研究;客室照明系统能够根据不同场景,为列车客室提供适宜的照明服务,包括全开、半开、全关和自适应模式;由于系统验证方面具有挑战性,提出一种基于串口测试装置的测试方法;串口测试装置硬件包括电源板卡、CPU板卡和两块串口卡,支持RS485、RS422、RS232方式与被测设备进行通讯;软件方面,能够解析通讯配置文件和协议,自动进行数据收发,使得测试时无需修改代码;串口测试装置能够对客室照明系统的控制端和照明端分别进行验证,有效解决了灯具数量不足和自适应控制条件难以模拟的问题;通过实验步骤和结果分析,验证了客室灯具状态反馈和自适应模式的测试方法;实验表明,使用串口测试装置能够有效提高测试的灵活性和效率,确保客室照明系统运行的稳定性。
Research on the control principle and testing method of a passenger compartment lighting system for electric multiple units(EMUs)is conducted.The passenger compartment lighting system can provide suitable lighting services for a train passenger compartment according to different scenarios,including fully open,half open,fully closed,and adaptive modes.Due to the challenges in system validation,a testing method based on a serial port testing device is proposed.The hardware of the serial port testing device includes a power board,a CPU board,and two serial port cards,which support a communication with the tested equipment in RS485,RS422,and RS232 modes;In terms of software,it can parse communication configuration files and protocols,automatically receive and send the data without the code modified during testing;The serial port testing device can verify the control-end and lighting-end of the passenger compartment lighting system separately,effectively solving the insufficient number of lamps and difficulty in simulating adaptive control conditions.Experimental procedures and result analysis verify the testing method for the status feedback and adaptive mode of the passenger compartment lights.Experiments show that a serial port testing device can effectively improve testing flexibility and efficiency,ensuring the stability of the passenger compartment lighting system operation.
