摘 要 轨道电路作为信号设备的三大件之一，是实现列车车辆占用检查的设备，它直接关系到行车安全，是电务人员维修、测试工作的重点，同时是信号监测设备重点监测的对象。通过监测轨道电压能有效地反映轨道电路的运行状态，实现故障的预防，并及时消除不良隐患。 论文主要针对25Hz交流轨道电路的轨道电压进行监测，采集过程的控制和采数据的处理以C++作为设计开发的主要语言工具、以SQL Server 2008作为数据库设计平台来完成的，通过使用C++ Builder软件和SQL Server 2008数据库，实现对交流轨道电路轨道电压的监测。其中采集到的数据以数据库表的形式记录，以对监测数据的调用、查询、报表打印功能。微机监测；铁路信号；轨道电路；模拟量采集Track circuit is one of the three important signal equipment, is the equipment to achieve the occupancy inspection of the train or vehicle, it is directly related to the traffic safety, is the key of telecommunication personnel maintenance, testing, and signal monitoring equipment, at the same time, it is the object of the monitoring equipment for signal monitoring. The monitoring rail voltage can effectively reflect the operating state of track circuit, realize the fault prevention, and eliminate the bad hidden danger in time. This thesis mainly aims at studying the 25 Hz AC track circuit voltage monitoring. The design is divided into two parts: the hardware part and software part. The function of hardware part is data acquisition, the function of software part is data processing and management. Hardware part adopts the core equipment ADAM-6017 of Advantech Company. The equipment can realize the real-time collection of analog quantity and digital quantity. Software can be divided into two parts: the control of the acquisition process and the processing of the collected data. C++ is the main language of design and development tools in Software part, and SQL Server 2008 is the database design platform. The track voltage of AC track circuit is monitored by using Builder C++ software and Server SQL 2008 database as design tools. The data collected is recorded in the form of database tables, by calling the stored procedure to achieve the function of query, report printing.
