The traffic safety of railway crossing is a major concern for public safety.When the train passes,the signal equipment works well or not is directly related to the traffic and pedestrains ’ safety on railway crossings.However,due to the wide ranges and cattered distribution of railway crossings,the signal equipment lacks of effective automatic monitoring and centralized management system,witch basically relies on manual patrol to carry out daily monitoring.It is difficult to confirm whether the signal equipment is running normally in time and exists potential safety questions.On the basis of fully understanding the railway crossing signal equipment and railway operation mechanism in China,this paper proposes to develop a kind of railway crossing signal equipment from the system planning,technical standards,communication schemes and software and hardware function settings,which can automatically monitor the operation status of the crossing signal equipment,record and analyze the data of the crossing signal equipment operation status and train location information.When the equipment discovers the problems,it will send the announcements to the railway crossing equipment remote monitoring system.According to the actual situation of the railway,the sub-station device of the monitoring system is developed and installed at the crossing,which communicates with the crossing signal equipment,collects and uploads the status information data of the equipment.At the same time,the vehicle-mounted equipment is developed to collect and upload train location information in the crossing section,and the main station of the monitoring system is developed for remote centralized management.The system has the functions of analysing and processing the data uploaded by the sub-station device.When the system detects the breakdown of the signal equipment at the crossing or the electrical characteristic index of the monitoring exceeds the limit,it sends an alarm to the relevant maintenance personnel in time to ensure that the signal equipment at the crossing is always under effective monitoring,and makes timely disposal response to the running state and the state of the train entering and leaving the crossing.Finally,through selecting the train and railway crossings,the results of the project are tested,and data are collected during the trial operation.Through data analysis,the functions and performances of the software and hardware of the system are evaluated objectively,and the expected objectives of the project are achieved...
