[0016] 图 4是本发明第一实施例提供的第四种数据存储方法的流程图；
[0017] 图 5是本发明第二实施例提供的一种数据存储装置的结构图。
本发明的实施方式
[0018] 为了使本发明的目的、 技术方案及优点更加清楚明白， 以下结合附图及实施例 ， 对本发明进行进一步详细说明。 应当理解， 此处所描述的具体实施例仅仅用 以解释本发明， 并不用于限定本发明。
[0019] 本发明实施例中， 监测写入机械硬盘的数据的速率， 在监测的写入机械硬盘的 数据的速率小于预设的第一写入阈值吋， 将后续的数据写入指定存储器， 所述 指定存储器的工作温度范围宽于机械硬盘的工作温度范围和 /或指定存储器的防 振能力强于机械硬盘的防振能力。
[0020] 为了说明本发明所述的技术方案， 下面通过具体实施例来进行说明。
[0021] 实施例一： [0022] 图 1示出了本发明第一实施例提供的第一种数据存储方法的流程图， 详述如下 [0023] 步骤 Sl l， 监测写入机械硬盘的数据的速率。
[0024] 由于机械硬盘通常内置振动频率和温度监测装置， 因此当机械硬盘所处环境的 振动频率或温度变化达到设定阈值， 机械硬盘的写操作会启动写后核对机制， 即对每次写入的数据， 重新读出， 确认写入无误后， 才返回写操作成功的结果 。 这种机制会造成机械硬盘在高频振动、 过高温、 过低温、 瞬间加速或减速的 吋候， 整体写入速率大幅降低。
[0025] 该步骤中， 当在机械硬盘写入数据吋， 可定吋或间隔一定的吋间或实吋计算写 入机械硬盘的数据的速率。 这里的机械硬盘是指车载的机械硬盘。
[0026] 步骤 S12， 在监测的写入机械硬盘的数据的速率小于预设的第一写入阈值吋， 将后续的数据写入指定存储器， 所述指定存储器的工作温度范围宽于机械硬盘 的工作温度范围和 /或指定存储器的防振能力强于机械硬盘的防振能力。
[0027] 其中， 预设的第一写入阈值小于机械硬盘正常工作吋的速率。
[0028] 当写入机械硬盘的数据的速率小于预设的第一写入阈值吋， 表明机械硬盘可能 已启动了写后核对机制， 即机械硬盘可能处于易坏 （如高温、 低温或振动环境 ) 的工作环境， 此吋， 为了避免由于机械硬盘突然出现故障而导致的数据没有 及吋写入的情况， 则将监测的写入机械硬盘的数据的速率小于预设的第一写入 阈值后的需要写入机械硬盘的后续数据写入指定存储器， 该指定存储器与机械 硬盘相比， 工作温度范围更宽， 防振能力更强， 该指定存储器可以为 SD卡或固 态硬盘等。
[0029] 当然， 为了避免存储重复的数据， 在指定存储器写入数据吋， 不再在机械硬盘 写入数据。
[0030] 图 2示出了本发明第一实施例提供的第二种数据存储方法的流程图， 在图 2中， 在所述步骤 S12之后， 包括：
[0031] 步骤 S13， 将少于指定字节的数据写入机械硬盘。 具体地， 当在指定存储器写 入数据吋， 可定期在机械硬盘写入少量数据， 以探测机械硬盘是否已恢复正常 的数据写入速率。 [0032] 步骤 S14， 在将少于指定字节的数据写入机械硬盘的速率大于或等于所述预设 的第一写入阈值吋， 将已写入指定存储器的数据写入机械硬盘， 并刪除已写入 指定存储器的数据。 具体地， 当判断出机械硬盘已恢复正常的数据写入速率后 ， 则将已写入指定存储器的数据都重写入机械硬盘， 并且， 为了节省指定存储 器的存储空间， 在将已写入指定存储器的数据都重写入机械硬盘后， 刪除已写 入指定存储器的数据， 这样， 即使指定存储器为小容量的 SD卡也能满足大数据 量的数据存储， 降低了设备成本。
[0033] 图 3示出了本发明第一实施例提供的第三种数据存储方法的流程图， 在图 3中， 除了包括步骤 S11和步骤 S12， 还包括：
[0034] 步骤 S15， 在监测的写入机械硬盘的数据的速率大于预设的第一写入阈值且小 于预设的第二写入阈值吋， 监测机械硬盘的工作温度。 具体地， 可通过温度传 感器监测机械硬盘的工作温度。 需要指出的是， 该预设的第二写入阈值与机械 硬盘正常工作吋的速率的差值小于指定的差值阈值， 即该预设的第二写入阈值 稍大于或等于机械硬盘正常工作吋的速率。
[0035] 步骤 S16， 在机械硬盘的工作温度大于预设的高温阈值或小于预设的低温阈值 吋， 将后续的数据写入指定存储器。
[0036] 上述步骤 S15和步骤 S16中， 由于预设的第一写入阈值小于机械硬盘正常工作吋 的速率， 因此， 为了能够在写入机械硬盘的速率下降之前发现写入数据的速率 可能将发生异常， 则当判断出写入机械硬盘的数据的速率大于预设的第一写入 阈值且小于预设的第二写入阈值吋， 监测机械硬盘的工作温度， 若发现机械硬 盘的工作温度处于异常状态， 则将后续的数据写入指定存储器。 由于在写入机 械硬盘的速率下降到预设的第一写入阈值之前就将数据写入指定存储器， 因此 ， 使得数据能够及吋写入， 从而减少数据丢失的概率。
[0037] 图 4示出了本发明第一实施例提供的第四种数据存储方法的流程图， 在图 4中， 除了包括步骤 S11和步骤 S12， 还包括：
[0038] 步骤 S17， 在监测的写入机械硬盘的数据的速率大于预设的第一写入阈值且小 于预设的第二写入阈值吋， 监测机械硬盘的振动频率。 具体地， 可通过振动传 感器监测机械硬盘的振动频率。 [0039] 步骤 S18， 在机械硬盘的振动频率大于预设的振动阈值吋， 将后续的数据写入 指定存储器。
[0040] 上述步骤 S17和步骤 S18中， 由于预设的第一写入阈值小于机械硬盘正常工作吋 的速率， 因此， 为了能够在写入机械硬盘的速率下降之前发现写入数据的速率 可能将发生异常， 则当判断出写入机械硬盘的数据的速率大于预设的第一写入 阈值且小于预设的第二写入阈值吋， 监测机械硬盘的振动频率， 若发现机械硬 盘的振动频率处于异常状态， 则将后续的数据写入指定存储器。 由于在写入机 械硬盘的速率下降到预设的第一写入阈值之前就将数据写入指定存储器， 因此 ， 能够及吋存储数据， 从而减少数据丢失的概率。
[0041] 可选地， 在所述步骤 S16之后， 包括：
[0042] 监测机械硬盘的工作温度， 在机械硬盘的工作温度大于或等于预设的低温阈值 且小于或等于预设的高温阈值吋， 将已写入指定存储器的数据写入机械硬盘， 并刪除已写入指定存储器的数据。 具体地， 当判断出机械硬盘的工作温度范围 恢复为正常的范围吋， 将已写入指定存储器的数据写入机械硬盘， 并刪除已写 入指定存储器的数据， 从而节省了指定存储器的存储空间。
[0043] 可选地， 在所述步骤 S18之后， 包括：
[0044] 监测机械硬盘的振动频率， 在机械硬盘的振动频率小于或等于预设的振动阈值 吋， 将已写入指定存储器的数据写入机械硬盘， 并刪除已写入指定存储器的数 据。 由于刪除已写入指定存储器的数据， 因此节省了指定存储器的存储空间。
[0045] 本发明第一实施例中， 监测写入机械硬盘的数据的速率， 在监测的写入机械硬 盘的数据的速率小于预设的第一写入阈值吋， 将后续的数据写入指定存储器， 所述指定存储器的工作温度范围宽于机械硬盘的工作温度范围和 /或指定存储器 的防振能力强于机械硬盘的防振能力。 由于写入机械硬盘的数据的速率小于预 设的第一写入阈值吋， 通常表明所述机械硬盘处于高温、 低温或振动环境等易 损坏的工作环境， 而指定存储器的工作温度范围宽于机械硬盘的工作温度范围 和 /或指定存储器的防振能力强于机械硬盘的防振能力， 因此， 在写入机械硬盘 的数据的速率小于预设的第一写入阈值吋， 将后续的数据写入指定存储器能够 避免由于机械硬盘突然出现故障而导致的数据丢失的情况。 [0046] 应理解， 在本发明实施例中， 上述各过程的序号的大小并不意味着执行顺序的 先后， 各过程的执行顺序应以其功能和内在逻辑确定， 而不应对本发明实施例 的实施过程构成任何限定。
[0047] 实施例二：
[0048] 图 5示出了本发明第二实施例提供的一种数据存储装置的结构图， 该数据存储 装置可应用于各种汽车中， 为了便于说明， 仅示出了与本发明实施例相关的部 分。
[0049] 该数据存储装置包括： 数据写入速率监测单元 51和第一指定存储器数据写入单 元 52。 其中：
[0050] 数据写入速率监测单元 51， 用于监测写入机械硬盘的数据的速率。
[0051] 具体地， 当在机械硬盘写入数据吋， 可定吋或间隔一定的吋间或实吋计算写入 机械硬盘的数据的速率。 这里的机械硬盘是指车载的机械硬盘。
[0052] 第一指定存储器数据写入单元 52， 用于在监测的写入机械硬盘的数据的速率小 于预设的第一写入阈值吋， 将后续的数据写入指定存储器， 所述指定存储器的 工作温度范围宽于机械硬盘的工作温度范围和 /或指定存储器的防振能力强于机 械硬盘的防振能力。
[0053] 其中， 预设的第一写入阈值小于机械硬盘正常工作吋的速率。
[0054] 其中， 该指定存储器与机械硬盘相比， 工作温度范围更宽， 防振能力更强， 该 指定存储器可以为 SD卡或固态硬盘等。
[0055] 当然， 为了避免存储重复的数据， 在指定存储器写入数据吋， 不再在机械硬盘 写入数据。
[0056] 可选地， 所述数据存储装置包括：
[0057] 写入速率探测单元， 用于将少于指定字节的数据写入机械硬盘。 具体地， 当在 指定存储器写入数据吋， 可定期在机械硬盘写入少量数据， 以探测机械硬盘是 否已恢复正常的数据写入速率。
[0058] 第一数据重写入单元， 用于在将少于指定字节的数据写入机械硬盘的速率大于 或等于所述预设的第一写入阈值吋， 将已写入指定存储器的数据写入机械硬盘 ， 并刪除已写入指定存储器的数据。 具体地， 当判断出机械硬盘已恢复正常的 数据写入速率后， 则将已写入指定存储器的数据都重写入机械硬盘， 并且， 为 了节省指定存储器的存储空间， 在将已写入指定存储器的数据都重写入机械硬 盘后， 刪除已写入指定存储器的数据， 这样， 即使指定存储器为小容量的 SD卡 也能满足大数据量的数据存储， 降低了设备成本。
[0059] 可选地， 所述数据存储装置包括：
[0060] 温度监测单元， 用于在监测的写入机械硬盘的数据的速率大于预设的第一写入 阈值且小于预设的第二写入阈值吋， 监测机械硬盘的工作温度。 具体地， 可通 过温度传感器监测机械硬盘的工作温度。 需要指出的是， 该预设的第二写入阈 值与机械硬盘正常工作吋的速率的差值小于指定的差值阈值， 即该预设的第二 写入阈值稍大于或等于机械硬盘正常工作吋的速率。
[0061] 第二指定存储器数据写入单元， 用于在机械硬盘的工作温度大于预设的高温阈 值或小于预设的低温阈值吋， 将后续的数据写入指定存储器。
[0062] 上述温度监测单元和第二指定存储器数据写入单元中， 由于预设的第一写入阈 值小于机械硬盘正常工作吋的速率， 因此， 为了能够在写入机械硬盘的速率下 降之前发现写入数据的速率可能将发生异常， 则当判断出写入机械硬盘的数据 的速率大于预设的第一写入阈值且小于预设的第二写入阈值吋， 监测机械硬盘 的工作温度， 若发现机械硬盘的工作温度处于异常状态， 则将后续的数据写入 指定存储器。 由于在写入机械硬盘的速率下降到预设的第一写入阈值之前就将 数据写入指定存储器， 因此， 使得数据能够及吋写入， 从而减少数据丢失的概 率。
[0063] 可选地， 所述数据存储装置包括：
[0064] 振动频率监测单元， 用于在监测的写入机械硬盘的数据的速率大于预设的第一 写入阈值且小于预设的第二写入阈值吋， 监测机械硬盘的振动频率。 具体地， 可通过振动传感器监测机械硬盘的振动频率。
[0065] 第三指定存储器数据写入单元， 用于在机械硬盘的振动频率大于预设的振动阈 值吋， 将后续的数据写入指定存储器。
[0066] 上述振动频率监测单元和第三指定存储器数据写入单元中， 由于在写入机械硬 盘的速率下降到预设的第一写入阈值之前就将数据写入指定存储器， 因此， 能 够及吋存储数据， 从而减少数据丢失的概率。
[0067] 可选地， 所述数据存储装置包括：
[0068] 第二数据重写入单元， 用于监测机械硬盘的工作温度， 在机械硬盘的工作温度 大于或等于预设的低温阈值且小于或等于预设的高温阈值吋， 将已写入指定存 储器的数据写入机械硬盘， 并刪除已写入指定存储器的数据。 具体地， 当判断 出机械硬盘的工作温度范围恢复为正常的范围吋， 将已写入指定存储器的数据 写入机械硬盘， 并刪除已写入指定存储器的数据， 从而节省了指定存储器的存 储空间。
[0069] 可选地， 所述数据存储装置包括：
[0070] 第三数据重写入单元， 用于监测机械硬盘的振动频率， 在机械硬盘的振动频率 小于或等于预设的振动阈值吋， 将已写入指定存储器的数据写入机械硬盘， 并 刪除已写入指定存储器的数据。
[0071] 由于刪除已写入指定存储器的数据， 因此节省了指定存储器的存储空间。
[0072] 本发明第二实施例中， 由于写入机械硬盘的数据的速率小于预设的第一写入阈 值吋， 通常表明所述机械硬盘处于高温、 低温或振动环境等易损坏的工作环境 ， 而指定存储器的工作温度范围宽于机械硬盘的工作温度范围和 /或指定存储器 的防振能力强于机械硬盘的防振能力， 因此， 在写入机械硬盘的数据的速率小 于预设的第一写入阈值吋， 将后续的数据写入指定存储器能够避免由于机械硬 盘突然出现故障而导致的数据丢失的情况。
