Abstract

The invention provides equipment for monitoring highway ETC air interface data. The equipment comprises a receiving antenna module, a radio frequency receiving module, a data transmission module, a USB interface module and a PC software part; the receiving antenna module is an energy converter, receives electromagnetic waves in a space and converts the electromagnetic waves into guided waves in a transmission line; the radio frequency receiving module is used for demodulating a signal in the receiving antenna module to form a baseband signal; the data transmission module is used for keeping the integrity of transmission data; the USB interface module carries out data transmission through a USB interface chip, and the design requirement of the DSRC air interface data monitoring instrument is met; and the PC software part performs data acquisition, data processing, data analysis, data display and parameter configuration through the PC software part.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a device for monitoring data at an ETC air interface of an expressway. Background technique [0002] At present, with the increasing demand of the transportation industry, expressway has become an efficient transportation method. However, with the rapid growth of traffic flow and the sharp increase of traffic volume, the toll station has become a traffic bottleneck on the expressway, which affects the traffic capacity of the expressway. Therefore, the electronic non-stop toll collection (ETC) system has become the current improvement An important means of traffic capacity. [0003] ETC system is an important application object of intelligent transportation. However, with the development of ETC application, improving ETC service quality and reducing failure rate have become prominent issues. There are many factors that affect ETC performance, including not only physical la...
