【摘要】 测控网络主要由测量设备、测量站、数据中心、测控指挥网络组成，是实现精确测控的基础网络，其可靠性要求较高。目前，测控网络中，测量设备与测量站之间是电话线路传输，测量站与数据中心间是光纤传输，其数据传输线路是混合式传输线路，为了判断整个线路数据传输的可靠性，需采用误码测试仪和电平检测仪器对线路进行测试。但是在对多条数据线路进行检测管理时，仪器检测实时性不强，给工作带来了诸多不便。如何利用现有技术，设计开发出一套能同时检测误码和电平特性的多线路状态测试系统具有重要的现实意义。多线路状态测试系统采用软硬件相结合的技术来实现。硬件方面首先分析了调制解调器、数字数据网和FPGA在测试方面的原理，然后根据接口或接入规范设计了各类电路，集成在以FPGA为控制单元的误码板和电平板上，并完成了FPGA硬件控制程序的编写。软件方面以VC++6.0为开发平台，按照软硬件间的通信规范，以模块化的方式实现了人机间的便捷操作。经用户测试，能够同时满足69路测控线路的误码测试和24路电平的实时监测，测试结果数据可实时传输给线路保障用户，极大提高了线路检测的效率。多线路状态测试系统在实际的运行过程中收到了较好的效果，测试系统检测的效果均达到了设计要求。目前该系统正在测控系统局部网络中进行试运行，通过用户检验后进行推广应用。更多还原

【Abstract】 Measurement and control network is mainly composed of measuringdevices, measuring stations, data center, C2network (command and controlnetwork). This network is the basis of precise measurement and control. Itrequires high reliability. Now, telephone lines between the measuring devicesand the measuring station, fibers between the measuring station and datacenter constitutes a hybrid-type transmission mode of the data. In order tojudge the reliability of data transmission in the entire line, checking the linerequires using of the BER tester and level detection equipment. But, the realtime performance of the instrument detection makes a lot of inconvenience inthe detection and management of multiple data lines. How to use existingtechnology to design and develop integrated circuit test system suited for bothbit error detection and level characteristics have important practicalsignificance.Multi-line state test system is composed of hardware and softwaretechnology to achieve. Part of hardware firstly analyzes the principles of theMODEM, the digital data network and the FPGA in the test, secondly designsvarious types of circuit based on the interface or access specification, oncemore integrates into the FPGA as the control unit of error plate and electricalplates, and finally completes FPGA hardware control program. Thecommunication between hardware and software specifications, convenientoperation between man and machine in a modular manner based on SoftwareVC++6.0platforms were developed. System tested by users can meet lineerror test for69lines and real-time level monitoring of24lines. The testresults can be transmitted to the user whose line is protected in real time. Thismethod greatly improves the detection efficiency of the line.Multi-line state test system have been received better results in the actual operation of the process, the effect of the test system detects have been metthe design requirements. Now, the test operation of the system is running inthe local network of monitoring and control system. After inspection by theuser, the system can be widely applied.更多还原
