摘　　要：高速公路不停车收费(ETC)已经实现全国联网,用户超过3 200万,参与建设的厂家近20余家,多厂家、多型号设备之间互联互通是系统的关键,如何能够快速准确地定位设备之间兼容性的问题,成为当务之急。针对需求,设计了基于科斯塔斯(Costas)环的新型ETC数据侦听和故障定位系统,描述了系统的工作原理、整体框架和开发思路。该系统已经开发完成并规模应用于ETC联网工作中,对故障定位、协议一致性判定、规范建设起到了不可替代的作用。该系统与现有方案相比其灵敏度提升15 d Bm,并且具备可同时侦听多信道、支持数据并发等突出优点。Electronic Toll Collection （ETC） has been networked. There are more than 32 million users and the manufacturers involved in the construction are nearly more than 20. The interoperability between differ-ent manufacturers and types of equipment is the key problem of system design. How to quickly and accu-rately positioning the compatibility between equipment becomes the urgent affair. According to the de-mand ,ETC data monitoring and fault location system based on the Costas loop is designed, and the working principle, overall framework and developing thought of the system are described. The system has been de-veloped and widely applied in ETC networking. It has played an irreplaceable role in the fault location, de-termination, protocol conformance specification for construction. Compared with the existing schemes,the proposed system has improved the sensitivity of 15 dBm and is featured by simultaneously intercepting mul-tiple channel and supporting data concurrency.
