環境感知是智慧車輛自主行駛的基礎和前提，傳感器數據採集和HIL仿真測試是中間的關鍵環節。Adopting high bandwidth Ethernet to transmit data can effectively improve the efficiency of data collection and testing, but faces the problem of converting different Ethernet protocols.宏虹車載乙太網 NETLion 1000可將100/1000BASE-T1訊號轉換爲100BASE-TX/1000BASE-T以太網。

NETLion 1000 Dual Media Conversion Network Tool

NETLion 1000 is a development tool for 100/1000BASE-T1 networks. It contains two modes of operation: Dual Media Conversion Mode and Network TAP Mode.

・Recording Data

・Analyze data traffic for test access points

・Converts 100/1000BASE-T1 physical layer signals to 100/1000BASE-T Ethernet signals to obtain the most accurate data through Layer 1 technology, i.e.Converts in-vehicle Ethernet signals to conventional Ethernet signals.

Product Highlights

・Supports logging and analysis of data traffic

・Includes two modes of operation: “Dual Media Converter Mode” and “Network TAP Mode”.”

・Converts 100/1000BASE-T1 physical layer to 100BASE-TX/1000BASE-T Ethernet (Dual Media Converter Mode)

・Highly accurate time-stamping function to accurately measure packet arrival time

Dual Media Conversion Mode

The NETLion 1000 converts up to two 100/1000BASE-T1 signals to 100BASE-TX/1000BASE-T Ethernet, which can beUsing two independent bi-directional converter channels, theThat is to say, it converts two signals at most, in both directions.

Network TAP Mode

It is possible to uncouple data from two 100/1000BASE-T1 lines and transfer it to two 100BASE-TX/1000/BASE-T interfaces without interfering with the communication in the 100/1000BASE-T1 network, i.e.Realizes one 100/1000BASE-T1 line bi-directional data uncoupling without affecting communication.

Case

Data Capture and ECU Refresh

Through this connection, various sensor data captures and ECU refreshes can be performed. For example, the firmware (software in the embedded system) is stabilized on the PC side and transferred through the NETLion1000, which can be used to update the LiDAR configuration to improve performance, add new functionality, or fix problems.

HiL Testing

NETLion 1000 can be used as a bridge between the ECU and the data injection equipment to ensure efficient and stable data transmission. The NETLion 1000 can be used as a bridge between the ECU and the data injection equipment to ensure efficient and stable data transfer, which in turn validates the design of the intelligent driving system, detects problems in advance, and improves testing efficiency.

Cable (Harness) Testing

・Check the status of the cable, e.g. open, short circuits, terminated.

・Detecting the length and polarity of the wires.

Cable (Harness) Testing

Bus simulation between ECU (100/1000BASE-T1) and PC during development.
