摘要:随着科技的发展，交通运输已经成为人们生活不可以缺少的一部分。本文针对轨道交通车站设备在实际生活中可能遇到的情况进行分析，设计出轨道交通车站设备监控系统。

本文设计的车站设备监控系统主要功能有：联锁故障模块、温湿度检测模块、火灾检测模块、照明检测模块、有毒气体检测模块、报警模块。随着单片机芯片的发展，单片机芯片在面向对象的实时控制和监控领域得到广泛的应用。单片机芯片主要有两大优势：（1）强大的处理能力并在内部集成硬件乘法器，有较快的处理速度。（2）单片机的中断源较多，并且可以任意嵌套，使用时灵活方便。本文设计的车站设备监控系统利用单片机作为主芯片，对各个模块进行控制，利用温湿度传感器对车站温度进行监控，利用烟雾传感器对车站内部烟雾颗粒浓度进行监控，利用光线采集电路度车站内部光照强度进行监控，利用气体传感器对车站内部有毒气体浓度进行监控，实现对车站设备全方位的监控。

Design Of Equipment Monitoring System For Rail Transit Station

Abstract:With the development of science and technology, transportation has become a part of people's lives can not be missing.In this paper, the rail transit station equipment in the actual life may be encountered in the situation analysis, design of rail transit station equipment monitoring system.

The main functions of the station equipment monitoring system are: interlocking fault module, temperature and humidity detection module, fire detection module, lighting detection module, toxic gas detection module, alarm module.With the development of single-chip chip, single-chip chip in the field of object-oriented real-time control and monitoring has been widely used.Single chip chip has two major advantages: (1) powerful processing power and integrated hardware multiplier, a faster processing speed.(2) single-chip interrupt source more, and can be arbitrarily nested, flexible and easy to use.This article designed the station equipment monitoring system using the single chip as the main chip, carries on the control to each module,the use of temperature and humidity sensors to monitor the temperature of the station, the use of smoke sensors on the station within the dark witch particles to monitor the use of light collection circuit degree of light intensity of the station to monitor the use of gas sensors on the station to monitor the concentration of toxic gases,Equipment all-round monitoring.

The paper has Figure 22, Table 1, reference 32 articles.
