摘要
由于现有列车车厢空气质量检测与自动控制系统的自动化程度较低,无法对空气质量变化做出及时的响应,导致空气质量控制效果差,因此文中进行列车车厢空气质量检测与自动控制系统的研究。首先设计系统硬件单元,其中包括主控单元、检测单元、显示单元与排风控制单元;在此基础上设计软件模块,包括主程序模块、温度检测数据读取模块、湿度检测数据读取模块与控制台模块。通过硬件单元与软件模块的结合设计,实现了列车车厢空气质量检测与自动控制系统的运行。设计仿真实验进行系统性能测试。结果显示:应用该设计系统后,列车车厢平均二氧化碳浓度小于1%;平均吹风感指标小于10%;平均预期不满意百分率为8.77%,远远低于现有系统。充分证实设计系统空气质量控制效果好。
As the existing air quality detection and automatic control system for train compartment has low degree of automation and cannot respond to the changes of air quality in a timely manner,resulting in the poor control effects of the air quality,an air quality detection and automatic control system for train compartment is proposed.The system hardware unit is designed,which includes the main control unit,detection unit,display unit and exhaust control unit.On this basis,the software modules are designed,including main program module,temperature detection data reading module,humidity detection data reading module and console module.The operation of the air quality detection and automatic control system for train compartment is realized by the combined design of the hardware unit and the software module.A simulation experiment was designed to test the system function.The experimental results show that,with the application of the designed system,the average concentration of carbon dioxide in the train compartment is less than 1%,the average blowing sensation index is less than 10%,and the average expected dissatisfaction percentage is 8.77%,which are far lower than those of the existing system.It is fully proved that the air quality control effect of the designed system is good.
