无论是在机械制造、医疗设备，还是在汽车电子产业、通信技术，我们都可以看见传感器在其中发挥重要作用。随着传感器的发展，很多行业也在积极开发利用传感器，很多新型的传感器都在广泛的被开放利用。
Whether in mechanical manufacturing,medical equipment,or in the automotive electronics industry,communication technology,we can see that sensors play an important role in it.With the development of sensors,many industries are actively developing and utilizing sensors,and many new sensors are widely used.
地铁成为人类利用地下空间的一种有效形式，充分缓解了城市的地面交通，以其运量大，准时性好，快速安全，交通效率高，利于环保等优点，成为现代城市地下空间建设的重点。但地铁在运营过程中，环境控制(简称环控)系统的用电量占了相当的比重，特别是带有空调的环控系统的用电量约占整个地铁耗电量的40%左右。但为了给乘客提供一个令人满意的舒适热环境，必须有地铁环控系统。
Metro has become an effective form of human use of underground space,which fully alleviates the urban ground traffic.With its advantages of large volume,good punctuality,fast and safe,high traffic efficiency and environmental protection,it has become the focus of modern urban underground space construction.But in the process of Metro operation,the power consumption of environmental control system accounts for a considerable proportion,especially the power consumption of environmental control system with air conditioning accounts for about 40%of the total power consumption of metro.However,in order to provide passengers with a satisfactory comfortable thermal environment,there must be a subway environmental control system.
因此，如何在环控系统中采取节能措施具有十分重要的意义。地铁的运量大，也就是乘客流量大，所需要的新风量变化大。因此地铁的空调负荷变化大，要实现节能必须借助于自动控制的手段。自动控制技术已经越来越多的应用于各类空调系统，在制冷设备集中、工况变化范围大的系统中，自控技术更是对系统的节能优化运行起到了很大作用。作为控制系统必不可少的组成部分，环境传感器在地铁中越来越多的起着重要的作用。
Therefore,how to take energy-saving measures in the environmental control system is of great significance.The large volume of subway traffic,that is,the large passenger flow,requires a large change in fresh air volume.Therefore,the air-conditioning load of the Metro varies greatly.In order to achieve energy saving,automatic control must be used.Automatic control technology has been more and more applied to all kinds of air conditioning systems.In the system with centralized refrigeration equipment and wide range of working conditions,automatic control technology has played a great role in energy-saving and optimal operation of the system.As an indispensable part of the control system,environmental sensors play an increasingly important role in the subway.
在地铁的环境控制系统里，我们使用了室内温湿度传感器、管道温湿度传感器以及Co2浓度传感器。
In the Metro environmental control system,we use indoor temperature and humidity sensors,pipeline temperature and humidity sensors and Co2 concentration sensors.
我们可以在车站的站厅以和站台区等公共区内以及重要的设备房内设置室内温湿度传感器，以监测车站实时的温度及湿度。这些参数可以帮助运营人员对车站各系统工况进行合理的调整，以保持车站公共区始终处于较为舒适的环境、确保设备房一直处于合适的温度之下。室内温湿度传感器一般装在车站站厅、站台以及设备房的墙面上或顶上。
We can set up indoor temperature and humidity sensors in the station hall,platform area and other public areas,as well as in important equipment rooms,to monitor the real-time temperature and humidity of the station.These parameters can help operators to adjust the working conditions of each system of the station reasonably,so as to keep the public area of the station in a more comfortable environment and ensure that the equipment room is always under the appropriate temperature.Indoor temperature and humidity sensors are usually installed on the walls or roofs of station halls,platforms and equipment rooms.
与此同时，我们可以在车站的新风室和回风室安装管道温湿度传感器，以监测室外新风的和车站内的温度以及湿度。环境控制系统可以根据传感器采集到的数据来判断车站的环境质量，并根据预先设计好的各种工况来进行自动切换，以实现自动控制系统对车站环境的自动控制，使得车站环境始终处于较为舒适的环境之中，并最终实现节能的减排的目的。管道温湿度传感器一般安装在新风室和回风室的墙壁上。
At the same time,we can install pipe temperature and humidity sensors in the fresh air room and return air room of the station to monitor the outdoor fresh air and the temperature and humidity in the station.The environmental control system can judge the environmental quality of the station according to the data collected by sensors,and switch automatically according to the pre-designed working conditions,so as to realize the automatic control of the station environment by the automatic control system,so that the station environment is always in a more comfortable environment,and ultimately achieve the purpose of energy saving and emission reduction.Pipe temperature and humidity sensors are usually installed on the walls of fresh air chamber and return air chamber.
我们还可以在车站的回风室内安装Co2浓度传感器，以监测车站内Co2的浓度。在车站里，由于人的呼吸，Co2的浓度会增加，当Co2浓度处于较大值时，当前车站的空气质量就对乘客的健康产生了威胁，所以，运营人员可以根据Co2浓度传感器采集上来的数据对车站公共区的工况进行及时的调整，以保证车站的空气质量始终处于好的状态。
We can also install a Co2 concentration sensor in the return air chamber of the station to monitor the concentration of Co2 in the station.In the station,because of human breathing,the concentration of Co2 will increase.When the concentration of Co2 is high,the air quality of the station threatens the health of passengers.Therefore,operators can timely adjust the working conditions of the public area of the station according to the data collected by the Co2 concentration sensor to ensure that the air quality of the station is always in good condition.
