摘要：
我们介绍了T-DAQ-P，一种紧凑且便携的数据采集和 telemetry 平台，旨在通过集成事件流、慢控制 telemetry 和面向操作员的调试工具，支持实验室和现场的探测器部署。该系统结合了Raspberry Pi 5主机用于多流处理、可视化和存储，以及专为传感器采集设计的Arduino UNO R4 WiFi微控制器。电子部分通过工程化的接口层集成了商用现成（COTS）模块，包括受保护的电源分配、逻辑电平转换和DB-37扩展连接器，暴露I2C-SPI-ADC线路供外部仪器使用。在 telemetry 方面，微控制器固件执行自动I2C发现、条件传感器处理，并输出带有XOR校验和显式块分隔符的类似NMEA的消息，使主机能够可靠解析和同步。有限状态控制（STOP-RUN-SIM-INIT）和看门狗式恢复操作在部分硬件可用性和现场故障下实现容错。主机软件采用多进程架构，具有独立的事件、 telemetry 和执行器流读取器，消息队列用于隔离，并在各流间实现一致的时间戳日志。模拟模式和集成命令通道允许端到端管道验证和快速调试，而无需完整的传感器可用性。本文详细描述了架构、电子集成、固件协议、主机软件设计和功能/工程验证程序，提供了一种可重复使用的蓝图，用于便携式仪器读取和上下文 telemetry 采集。
英文摘要：
We present T-DAQ-P, a compact and portable data acquisition and telemetry platform designed to support detector deployments in laboratory and field conditions by integrating event streaming, slow-control telemetry, and operator-oriented commissioning tools in a single unit. The system combines a Raspberry Pi 5 host for multi-stream ingestion, visualization, and storage with an Arduino UNO R4 WiFi microcontroller dedicated to sensor acquisition. The electronics integrate commercial off-the-shelf (COTS) modules through an engineered interface layer including protected power distribution, logic-level adaptation, and a DB-37 expansion connector exposing I2C-SPI-ADC lines for external instrumentation. On the telemetry side, the microcontroller firmware performs automatic I2C discovery, conditional sensor handling, and outputs framed NMEA-like messages with XOR checksum and explicit block delimiters, enabling robust parsing and synchronization on the host. A finite-state control (STOP-RUN-SIM-INIT) and watchdog-style recovery actions implement resilience under partial hardware availability and field failures. The host software adopts a multi-process architecture with independent readers for event, telemetry, and actuator streams, message queues for isolation, and coherent time-stamped logging across streams. A simulation mode and integrated command channel allow end-to-end pipeline verification and rapid commissioning without full sensor availability. The paper details architecture, electronics integration, firmware protocol, host software design, and functional/engineering validation procedures, providing a reproducible blueprint for portable instrumentation readout and contextual telemetry acquisition.
