硬件质量与测试研发Hardware Quality & Validation
在智能安防与 AIoT 产品研发验证场景中，参与硬件功能测试、通信接口验证及异常问题复现，协助开展工程验证、设计验证和产品验证阶段的质量工作。Participated in hardware validation and quality assurance for smart security and AIoT products, focusing on functional testing, communication interfaces, abnormal-condition testing, and issue reproduction across engineering validation stages.
主要工程工作Engineering Work
- 硬件接口与功能验证Interface validation
根据测试要求检查 SPI、I²C、UART、CAN、Ethernet 等接口相关功能，记录测试条件、预期结果与实际现象，辅助定位通信及设备行为异常。Tested relevant functionality involving SPI, I²C, UART, CAN, and Ethernet interfaces, documenting test conditions, expected behavior, observed failures, and reproducibility.
- 可靠性与异常场景测试Reliability testing
参与高低温、异常上电及长时间运行测试，记录设备状态、异常日志与复现条件，配合研发人员进行复测和问题跟踪。Supported high/low-temperature, abnormal power-on, and extended-operation testing, collecting logs and documenting failure conditions for engineering follow-up.
- 测试数据处理Test data processing
使用 Python 对测试日志进行批量整理、筛选和分类，减少重复人工检查，并提高异常记录的检索效率。Used Python scripts to organize, filter, and classify testing logs, reducing repetitive manual analysis and improving issue traceability.
- 跨团队问题跟踪Cross-functional collaboration
整理测试用例、异常现象和复测结果，与硬件、软件及质量团队沟通，支持问题闭环。Coordinated test cases, failure descriptions, and retest findings with hardware, software, and quality teams.
技术工具及方法Tools & Methods
工程实践收获Engineering Takeaways
形成从测试条件、预期行为到实际现象和复测记录的工作习惯；通过清晰记录支持研发排查，并区分异常复现与根因确认。Developed a disciplined approach to recording conditions, expected behavior, observations and retest findings, supporting engineering investigation while distinguishing reproducibility from root-cause confirmation.
