3. 支持分布式电源 / 储能 / 充电桩接入相关数据扩展存储。 | -#### 3.6.3 性能需求 -##### 故障录波高速写入需求 -GB/T 35732-2025 6.2.2.l 明确要求 DTU 具备故障录波功能,录波格式遵循 GB/T 14598.24。典型故障录波参数: -- 采样率:128 点 / 周波(6400 点 / 秒,50Hz 系统) -- 通道数:16 通道(8 路电流 + 8 路电压) -- 采样精度:16 位(2 字节 / 点) -- 录波时长:3 秒(故障前 0.5s + 故障后 2.5s) -单次故障录波数据量 = 16 通道 × 6400 点 / 秒 × 2 字节 × 3 秒 = **614.4KB**。故障发生时,需在**100ms 内完成全部录波数据写入**(避免后续数据覆盖),因此最低写入速率要求:614.4KB × 8bit / 0.1s = **49.15Mbits/s**。考虑到故障录波同时可能伴随 SOE 事件写入、实时数据采集等并发操作,需预留至少 1 倍余量,因此要求 **≥100Mbits/s**。 -##### 固件远程升级效率需求 -GB/T 35732-2025 6.4.1 要求 DTU 支持远程固件升级。典型 DTU 固件大小为 16~32MB,若传输速率过低: -- 32MB 固件以 50Mbits/s 传输需约 5.1 秒 -- 以 100Mbits/s 传输需约 2.6 秒 -- 以 400Mbits/s(GD5F2GQ5UE 的 QSPI 模式)传输仅需 0.6 秒 - -32MB 固件区包含 256 个 128KB 块,若每个块擦除时间为 5ms,则总擦除时间为 1.28 秒;若为块擦除时间10ms,总擦除时间为 2.56 秒;若块擦除时间100ms,总擦除时间将达 25.6 秒,严重影响升级效率和系统可用性。 - -**工程要求**:固件升级总时间(擦除 + 写入 + 校验)应≤30 秒,避免长时间占用通信链路和 CPU 资源。若传输速率低于 100Mbits/s,在通信不稳定场景下极易出现升级失败。 -##### 多任务并发访问需求 -DTU 运行时通常同时执行以下存储操作: -- 实时数据写入(1 次 / 分钟) -- SOE 事件突发写入 -- 主站历史数据读取 -- 日志追加写入 -若存储芯片带宽不足,会出现操作阻塞,导致 SOE 事件延迟、实时数据丢失等问题。100Mbits/s 的速率可保证 4~5 个并发操作同时进行而不出现瓶颈。 -##### SOE 分辨率的硬性约束 -GB/T 35732-2025 8.1.4.3 明确规定:**SOE 事件顺序记录分辨率≤2ms**。若页写入时间过长(如 1ms),则在写入过程中发生的 SOE 事件会被延迟记录,最坏情况下时间误差可达 1ms,再加上 CPU 处理延迟、中断响应延迟等,总误差可能超过 2ms 的标准要求。 -**工程阈值**:页写入时间应≤SOE 分辨率的 1/4,即 2ms ÷ 4 = **500μs**,以保证足够的时间余量。 -##### 故障录波连续写入需求 -故障录波是连续数据流,若页写入时间过长,会导致缓存溢出,造成录波数据丢失。按 16 通道、128 点 / 周波计算,每秒产生 200KB 数据,对应每秒需写入 100 页(2KB / 页)。若页写入时间为 500μs,则 100 页写入总时间为 50ms,仅占 CPU 时间的 5%,不会影响其他任务;若页写入时间为 1ms,则占 CPU 时间的 10%;若超过 2ms,会导致 CPU 负载过高,系统卡顿。 -##### 历史数据循环覆盖需求 -GB/T 35732-2025 6.2.1.d 要求 DTU 具备历史数据循环存储功能。当存储空间满时,需擦除最早的块以写入新数据。若块擦除时间过长(如 20ms),则在擦除过程中,新产生的数据无法写入,可能导致数据丢失。特别是在故障频发时段,短时间内会产生大量 SOE 和录波数据,对擦除速度要求更高。 -**工程要求**:单次擦除操作应在系统可容忍的最大延迟内完成,通常为 5ms,以保证实时数据不丢失。 - -| 性能指标 | 要求值 | 测试条件 | -| ------------- | -------------------------- | ------------------------------------------------------------------------ | -| 最小本地存储空间 | ≥128MB(基础版);≥256MB(标准款) | 常温、正常供电,终端空载运行 | -| 历史运行数据存储时长 | ≥15 天(1 次 / 分钟采样,全遥测 / 遥信) | 额定采样频率,循环存储模式 | -| SOE 事件最大存储条数 | ≥10000 条 | 标准 SOE 格式,带毫秒级时间戳 | -| 故障录波存储次数 | ≥50 次故障 | 16 通道、3s / 次,标准 COMTRADE 格式 | -| 操作 / 告警日志存储条数 | ≥5000 条 | 含操作人、时间、内容、结果 | -| 定值 / 参数存储 | 永久保存,掉电不丢失,≥3 个历史版本 | 断电重启、后备电源切换后 | -| 固件存储版本数 | ≥2 个(当前版 + 备份版) | 远程升级、本地升级后 | -| 数据读写可靠性 | 写入寿命≥10 万次,数据保存≥10 年 | 工业级存储芯片,常温环境 | -| 掉电数据保持时间 | ≥10 年 | 无外部供电,芯片非易失性存储 | -| 数据传输速率 | ≥100Mbits/s | 通过测量连续读写固定大小数据块的总时间,计算出实际传输速率 | -| 页写入时间 | ≤500μs | 测量从发送 "页编程" 命令到芯片完成写入(R/B# 变高)的时间,即为单页写入时间。需测试**随机页写入**和**顺序页写入**两种情况 | -| 块擦除时间 | ≤5ms | 测量从发送 "块擦除" 命令到芯片完成擦除(R/B# 变高)的时间,即为单块擦除时间。需测试**新块擦除**和**多次擦写后的块擦除**两种情况 | -#### 3.6.4 安全需求 -- 重要数据(定值、参数、证书、日志)采用**加密存储**,使用国密算法加密,防止非法读取、篡改、伪造。 -- 支持存储访问权限控制:仅授权主站、本地运维账号可读取 / 修改 / 导出数据。 -- 存储参数、定值、日志文件具备防篡改与操作留痕,所有修改行为自动记入审计日志。 -- 故障录波、SOE、电能量等关键数据具备写保护机制,仅可追加不可删除。 -- 支持存储数据完整性校验,上电自动校验,异常立即上送告警。 -#### 3.6.5 运维需求 -- **参数配置**:支持本地 / 远方配置存储策略、循环覆盖阈值、重要数据保护策略、清理规则。 -- **状态监测**:实时监测总容量、已用容量、剩余容量、各分区使用率、存储芯片健康状态,可上送主站。 -- **数据管理**:支持主站远程清理普通历史数据,重要数据需授权才可清理;支持一键备份 / 恢复参数、定值。 -- **故障诊断**:支持存储故障自诊断,可定位芯片异常、空间不足、数据损坏、写入失败等原因并上送。 -- **远程维护**:支持远程导出录波、日志、SOE,远程备份 / 恢复配置,不影响终端正常采集与控制业务。 -### 3.7 电源管理功能(FUN-006) -#### 3.7.1 功能概述 -管理双路供电电源和无缝切换至锂电池后备电源,监控电源状态,并在电源异常时提供告警。 -#### 3.7.2 子功能需求 -| 子功能编号 | 子功能名称 | 优先级 | 详细需求描述 | -| :--------- | :-------- | :-- | :----------------------------------------------------------------------------------------------------- | -| FUN-006-01 | 双路电源无缝切换 | P0 | 1. 任一路供电不足或消失时,终端能不间断正常运行 [1](标准6.2.4.a)。

的基础定义、典型部署场景(如石油化工、智能制造),以及其与可编程逻辑控制器(PLC)在传统架构下的能力对比。文档重点介绍了工业监控的“三遥”标准能力集(遥信、遥测、遥控),并简要提及了电力配电自动化领域专用终端(DTU/FTU/TTU)与通用 RTU 的派生关系。该源文件为构建工业控制硬件谱系与边缘节点知识树提供了基础概念框架,但在具体通信协议栈、硬件架构选型及现代设备融合趋势方面留有进一步扩展空间。 \ No newline at end of file diff --git a/write.ts b/write.ts new file mode 100644 index 0000000..4b2d046 --- /dev/null +++
