Abstract Due to the safety and comfort problems of subway stations, we propose a system that can monitor environmental information by constructing a fundamental information monitoring platform based on a WSN. The basic idea is to deploy a large number of sensor nodes with the ability of sensing, computing and communicating in the station to form a wireless network and the information collected by different nodes will be sent in real time to the backend database. Then, we can acquire all kinds of monitoring information from the platform after a series of processing steps conducted by the platform. If any abnormal data ware found, the corrective measures will be taken immediately. The main features of our proposed platform are the design of the system’s functional structure and the design of the software and hardware modules. Also, we propose to incorporate a dormancy mechanism to save energy. Keywords Monitoring platform

Introduction The urbanization process has resulted in the rapid development and construction of urban rail transit systems. However, due to the low level of the information and integration, traditional management approaches of construction and operation have not adapted to the requirements of such systems. With more and more rail operation rely on the network, informational and intelligent collection methods are urgently needed to acquire environmental information. Railway stations have encountered many difficulties in the process of constructing the infrastructure of railway stations. The problems associated with the aging of the structure have become increasingly prominent as the service life has been extended. The underground structure of urban subway tunnels is subject to ground water erosion and vibration loading imposed by the trains. So, safety monitoring work, which is difficult to accomplish, has become very important. Because the rail networks are located underground, most stations may have many limits when they are compared with other types of space, Such as insufficient daylight, the lack of fresh air, air pollution, and high temperature [1]. All of these factors have a significant effect on the comfort of the people who use the stations. Thus, work designed to monitor the comfort levels is also important [2]. In order to improve the safety and comfort index of subway stations, we have established a
