【摘要】 根据铁路道口安全管理的需要,本文设计开发了一套基于DSP和以太网技术的铁路道口监测系统,介绍了它的硬件组成和软件结构。该系统使得铁路道口监测网与信息网融为一体,实现了对列车速度、车厢数目和列车行进的方向等列车运行状态数据的实时采集、网络传输、动态显示、入库保存以及历史数据查询等功能,并且可以同时向道口站工作人员发出声光报警信号,实用结果证明了该方案的正确性。更多还原

【Abstract】 According to the security requirements of Railroad Crossing, a set of railroad crossing monitor system based on DSP and Ethernet technology is designed. The structure of its hardware and software are presented. The monitoring network integrates the Internet perfectly. It can measure several kind of train state information, such as the current speed?the number of passing carriages and the direction of the train and etc. Further more, the real-time acquiring?networked transmitting?dynamic displaying?data-base saving and later querying of the train state data are realized. At the same time,the monitor system can also send a sound-light signal to the operator at the crossing to notify him that a train will pass through. The practical results have proved the correctness of the design schemes.更多还原
