1. New Product Launch
The Highway Transportation Division of Doewe Technologies, with years of expertise in testing solutions for CCTV surveillance systems and ETC toll collection systems in highway electromechanical engineering, proudly announces the official release of ProEye in October 2023. This professional ETC communication process testing software complies with JTG 2182 standards for ETC protocol conformance testing, adapts to OBU-RSU communication interactions, and delivers precise analysis of ETC transaction data.
ProEye is a specialized tool for analyzing ETC system communication protocols (conformance testing). It processes recorded IQ files containing ETC RF interaction data, supporting common IQ formats while parsing、RF performance metrics、Application-layer key interaction commands and feature-specific data.
2. System Functional Framework
1、IQ File Import:Supports importing and analyzing multiple IQ file formats.
2、RF analysis: mainly includes core functions such as radio frequency parameter testing and calculation, spectrum display, and demodulation.
Spectrum display and radio frequency parameter display: Supports IQ file spectrum display and related radio frequency parameter display.
Demodulation: Supports ASK/FSK demodulation methods.
3、Data Parsing：Supports parsing of key interaction statements and characteristic data of the application layer and device application layer.
Data display: Supports displaying demodulated and decoded data (ASK demodulation and FM0 decoding).
Retrieval and judgment of key interaction statements: Supports retrieving key interaction statements and judging their existence.
4、Screenshot output: Supports screenshot of the software interface.
3. Software Features
The software interface is well-structured and user-friendly. All software functions provide C# APIs for secondary development.
1、Supports IQ file reading and identification
Based on the 《GB/T 20851-2019》 series standards, it supports the demodulation of RSU downlink signals and OBU uplink signals in the read IQ files.
2、Supports parsing of radio frequency indicators
Based on the 《GB/T 20851-2019》 series standards, it supports testing and parsing radio frequency indicators such as signal strength, carrier frequency, carrier tolerance, modulation coefficient and occupied bandwidth. It supports parsing ETC uplink and downlink data after demodulation and decoding (ASK demodulation and FM0 decoding), and can display the decoded data.
3、Supports retrieval and judgment of key interaction statements and characteristic data
It can automatically search for key interaction statements: such as preamble, BST, VST, SetMMI.rq, SETMMI.rs, splicing statements, gantry number and license plate number, etc. It supports automatic display of retrieval results to judge whether the communication process of the ETC system is normal. It supports software interface screenshot output.
