Design And Implementation Of Safety Protection System For Crossing

There are railway crossings in many cities,and they are not only located in the railway,but also in the intersection of highway and railway.Therefore,the safety management of railway crossing is very important,especially if people relax their vigilance when passing the crossing,it is easy to have a malignant traffic accident.The traditional railway crossing adopts camera,red light signal detector and so on.Although this method can improve the early warning ability of railway crossing,there are some problems such as unclear signal recognition,complex image analysis algorithm and so on.In recent years,with the rapid development of MMW radar,especially the use of Doppler effect,the measurement and analysis of the distance and speed of abnormal objects can be realized quickly.This paper designs and develops a railway crossing radar early warning safety protection system.The main work of this paper is as follows:(1)This paper adopts the development mode of C/S,builds the system architecture according to the user interface layer,logic processing layer and data management layer,and uses Java as the development language to design,realizes the main functions of the railway crossing radar early warning and safety protection system.The data generated in the system operation process is stored and managed by SQL Server 2012 database.(2)This paper focuses on the analysis and research of the application of trd-1000 radar.The radar is deployed at the railway crossing,and a new railway crossing radar early warning and safety protection system is established in cooperation with the crossing monitoring system.The system is able to detect within 1 km before the train enters the crossing and feedback the data to the computer.(3)In this paper,the radar initialization function,data query and analysis function,crossing monitoring function and data management function of the railway crossing radar early warning system are realized,and the black and white box test method is used to test the system.The radar early warning and safety protection system of railway crossing developed in this paper has been deployed at the level crossing of Jinan City.After the test system runs well,when the train is one kilometer away from the crossing,the radar can detect the train.In addition,combined with the picture and data of video monitoring,the ability of the radar early warning and safety protection system of railway crossing has been greatly improved.
