1  功能概述FUNCTIONAL OVERVIEW

知从玄武标定上位机工具是一种基于ASAM标准的通用测量与标定协议工具，支持多通信协议（如CAN、CANFD、Eth等），专为汽车电子控制单元（ECU）的在线标定、数据采集和调试设计。其核心功能包括：

实时数据采集：支持Polling（轮询）和DAQ（数据采集）两种模式。在线参数标定：动态调整ECU参数并实时生效，支持块标定、二维数组标定。Flash编程：将标定后的参数生成hex文件，可烧录存储至ECU的Flash中，确保持久化生效。多协议兼容：支持XCP-on-CAN、XCP-on-CANFD，XCP-on-Ethernet等多种传输层，适配不同车载网络环境。

The ZC.XuanWu Calibration Tool is a general-purpose measurement and calibration protocol tool based on ASAM standards, supporting multiple communication protocols (such as CAN, CANFD, Ethernet, etc.). It is specifically designed for online calibration, data collection, and debugging of automotive electronic control units (ECUs). Its core functions include:

Real-time Data Collection: Supports both Polling (cyclic query) and DAQ (data acquisition) modes.

Online Parameter Calibration: Dynamically adjusts ECU parameters that take effect in real-time, supporting block calibration and 2D array calibration.

Flash Programming: Generates hex files from calibrated parameters, which can be programmed and stored into the ECU's Flash memory to ensure persistent effectiveness.

Multi-Protocol Compatibility: Supports transport layers such as XCP-on-CAN, XCP-on-CANFD, and XCP-on-Ethernet, adapting to different vehicle network environments.

4  开发背景 DEVELOPMENT BACKGROUND

 随着汽车电子化与智能化进程加速，电子控制单元（ECU）的功能复杂度呈指数级增长。21世纪初，传统汽车行业的标定逐渐暴露以下局限性：

带宽瓶颈：仅支持CAN总线，最大理论带宽1 Mbps，无法满足高频率数据采集（如电机转速、电池单体电压）需求。

协议僵化：无法适配CANFD、Ethernet等新型车载网络，制约了多域控制器（如域控、中央计算平台）的发展。

资源占用高：需在ECU中预分配固定内存块（Daq List），导致内存利用率低，尤其在小内存MCU中矛盾突出。

功能单一：缺乏动态标定、安全访问等高级功能，难以应对ISO 26262功能安全与信息安全要求。

知从玄武标定工具适配多种总线类型，支持市场主流硬件设备，支持多种类型的测量与标定，图形化界面，操作简便，满足客户需求。

With the acceleration of automotive electrification and intelligentization, the functional complexity of Electronic Control Units (ECUs) has grown exponentially. In the early 21st century, traditional automotive calibration gradually revealed the following limitations:

Bandwidth Bottleneck: Supported only CAN bus with a maximum theoretical bandwidth of 1 Mbps, failing to meet high-frequency data acquisition requirements (e.g., motor speed, battery cell voltage).

Protocol Rigidity: Incompatible with emerging in-vehicle networks like CAN FD and Ethernet, constraining the development of multi-domain controllers (e.g., domain controllers, central computing platforms).

High Resource Consumption: Required pre-allocated fixed memory blocks (DAQ List) in ECUs, resulting in low memory utilization, particularly problematic for small-memory MCUs.

Limited Functionality: Lacked advanced features such as dynamic calibration and secure access, making it difficult to comply with ISO 26262 functional safety and cybersecurity requirements.

ZC.XuanWu Calibration Tool addresses these challenges by:Multi-bus compatibility: Adapting to various bus types (CAN/CAN FD/Ethernet).Mainstream hardware support: Seamless integration with industry-standard devices.Comprehensive measurement & calibration: Supporting diverse calibration types.User-friendly GUI: Featuring intuitive graphical interfaces for simplified operations.Customized solutions: Fully meeting customer requirements across scenarios.
