In order to ensure the driving safety of railway crossings, a new set of railway crossing driving safety monitoring system has been successfully developed by using the Internet access platform GPRS of the mobile digital communication public network as a means of communication.The system can not only display the train running conditions at the railway crossing in real time, but also carry out informatization processing of the monitoring data in combination with the train's traveling position. And use data analysis capabilities to warn of possible security issues.The technology is being tested on trains and railroad crossings. The results show that when the system detects that the electrical characteristic index exceeds the safe range or there is a problem with the crossing signal equipment, it can quickly send an alarm to the staff, and quickly make corresponding processing according to the state of the train entering and leaving the crossing and the running state.
