Mechanism Research On The Prevention Of Squeeze Turnout Accident Based On RFID

Railway is the country’s infrastructure, the backbone of the transportation system, the artery of national economy and mass transport in today’s China play an important role. Railway transportation safety can satisfy the requirement of national key material, engineering construction, scientific research base and military transportation, but also brought vigor and vitality into local economic development and technological development. With the rapid development of China’s railway transport, protect the security of rail transport becomes more important. Approach, one of the three inertial accident, in the process of changing lanes or through route squeeze the fork accident still is the dead security guard’s facilities. Fork to prevent accidents on squeeze the fork to ensure safe and smooth rail transport has great significance.In this paper, based on the comparison of the existing anti-extrusion fork improvement program, summarizes the advantages and disadvantages of existing programs, get the depth understanding of the driving environment in the switch section, careful study of the interlock system between turnout and signal, between turnout and through route. After a lot of squeeze the turnout accident analysis, indicating the reason is due to crowd turnout occurred in the absence of the majority of shunting operation code area, the vehicle in this segment,traffic safety equipment can not play an effective control, it need to manually confirm the signal. frequently people neglect so cannot carefully executed according to standardized operations. In this case, by improving the management mechanism to control the squeeze bifurcated accident that produce little effect. On that basis, we propose to increase device that can turn the situation will be very meaningful to the vehicle passed.To maximize eliminate driver’s guesswork that brought traffic safety problems, the need to ensure that trains can receive information turnouts open state. Need to install a wireless communications device, by comparison of existing wireless communication method then choose the RFID. Paper proposed solution is to install a set of RFID equipment, install the front beneath the locomotive and turnout RFID reader suitable location to install the front RFID tags. When the locomotive enters the acceptable range of information, in-car device receives a signal to confirm patency turnout, if the opening is right does not affect normal driving, if the error is opened automatically take emergency stop. In order to ensure traffic safety, prevent squeeze fork accidents occur.
