| 摘 要： | 针对传统安全监控措施不完善的问题，设计了一套用于监控铁路路障的视频监控及报警硬件系统。系统中采用了，TI（TExAs INsTuMENT）的多媒体处理芯片TMS320DM642作为主要处理器，用于对系统所采集到的视频信号进行识别与处理，当系统判定路口中存在路障时，则通过无线收发器对列车发出报警信号，列车员收到信号后便可以对列车制动从而避免事故的发生。整个系统分为两个部分，一部分设计为架设在铁路口边，另一部分则设置在列车上。其它主要选用的器件还有视频解码芯片TVP5150PBS和无线收发芯片nrf401等。 |

| Abstract: | This presented a hardware which was designed to monitor the railway crossing.The authors chosed TI(TEXAS INSTRUMENT)'s multimedia processor TMS320DM642 as the main processor and it was ased to process the video signal capmred by the system.When there is the obstruction on the railwasy,the wireless system will send the alarm signal to the train and thus the train can be stopped.The whole system contains two parts.One of them is designed to be placed at the crossing,and the other will be placed in the train.Video decoder TVP5150PBS and wireless RF transceiver ntf401 are applied in this system. |
