} ,该速率集合包括 N+2个等级。 其中 VD是数据卡的下行速率等级, Vu是数据卡的上行速率等级, VD(N+ 1)是 数据卡支持的最大下行速率等级,VU(N+ 1)是数据卡支持的最大上行速率等级, 上行速率等级由小到大逐级递增, 下行速率等级由小到大逐级递增, 其取值 可以手动由小到大预先设定, 也可以按如下公式计算确定:
VD„=VD(N+ i)/2(N-n+ l) , 其中 n= l,...,N;
Vu„=VU(N+ i)/2(N-n+ l) , 其中 n= l,...,N。 步骤 102中调节上述数据卡的数据传输速率包括: 按照上述速率集合中 的速率等级对数据卡的上行速率和 /或下行速率进行控制, 具体地, 控制方式 包括下述的一种或几种:
1 ) 按照速率集合中的上行速率对数据卡的上行速率进行控制, 不对数 据卡的下行速率进行控制;
2 ) 或按照速率集合中的下行速率对数据卡的下行速率进行控制, 不对 数据卡的上行速率进行控制; 3 ) 按照速率集合中的上下行速率对数据卡的上下行速率同时进行控制。 步骤 102使用釆样得到的温度调节上述数据卡的数据传输速率的步骤包 括: 将釆样得到的温度与预设的门限进行比较, 确定速度传输速率调节的方 向及速率等级; 才艮据确定的方向及速率等级调整上述数据卡上的数据传输速率。 优选地, 上述门限包括: 紧急门限、 高温门限和氐温门限; 如果上述数据卡上受保护器件的釆样温度至少有一个大于或等于上述紧 急门限, 则将上述受保护器件的数据传输速率下调至 0, 停止数据传输; 如果上述数据卡上受保护器件的釆样温度至少有一个大于或等于上述高 温门限且全部小于上述紧急门限, 则将上述受保护器件的数据传输速率下调 一个速率等级; 如果上述数据卡上受保护器件的釆样温度全部小于上述低温门限, 则将 上述受保护器件的数据传输速率上调一个速率等级; 如果上述数据卡上受保护器件的釆样温度全部小于上述高温门限且至少 有一个大于或等于上述低温门限, 则保持上述受保护器件中数据传输速率不 变。 步骤 101和步骤 102是釆用漏桶流量整形算法调节上述数据卡的数据传 输速率。 速率控制是釆用漏桶流量整形算法来实现, 该算法原理如图 2所示, 如 果分组到达, 则会被放入漏桶中, 如果桶满了, 则分组会被丢掉, 分组会以 一个恒定的速率发送, 其大小等于漏桶洞的大小。 所以, 如果我们控制漏桶 洞的大小, 就可以控制分组的发送速率了。 当进入漏桶的分组数据速率会大 于漏桶漏出的分组数据速率时, 漏桶中的分组会†曼' 1"曼累积起来, 最后会出现 因漏桶满而将一部分分组丢去, 当接收端检测到分组丢去情况后, 会通过
TCP/UDP传输层或应用层请求发送端将丢去的组数据重传,发送端检测到分 组情况后, 就会认为传输链路出现了拥塞, 于是会降低发送速率, 确保数据 可靠传输。 以上只是漏桶原理介绍, 实际上可以使用队列来实现漏桶功能。 图 3才艮 据是本发明实施例的使用先入先出队列 (FIFO ) 实现漏桶速率控制功能原理 的示意图, 如图 3所示, 当从网络侧或 PC侧到来的分组报文达到无线数据 卡时, 速率控制模块按报文到达的先后顺序让报文进入 FIFO队列, 同时, 在 FIFO队列的出口让 4艮文按进队的顺序出队, 先进的 4艮文将先出队, 后进 的报文将后出, 当分组报文进入 FIFO队列的速度大于接口能发送的速度时, FIFO队列长度就会增加, 当队列的长度达到某一最大值后, 所有新到来的 4艮 文因队列满而将被丢弃。我们可以通过限制 FIFO队列的出口在单位时间 t(ms) 内分组报文的突发尺寸大小 s(Byte)字节)来实现速率控制功能, 这样数据传 输速率就被调节为: V=8* ( s/t ) Kbps。 我们可以通过调整 t和 s的大小来实现不同速率等级控制功能, 当 s为 0 时数据传输速率为 0, 即停止数据传输, 假设数据卡最大的上行和下行速率 分别为 VU(N+1)和 VD(N+1), 此时对应一组 s和 t, 介于" 0"与 VU(N+1)和 VD(N+1) 之间的速率等级可以手动设定也可以按照也可以按如下公式计算确定:
VDn=VD(N+1)/2(N-n+1), 其中 n=l,...,N;
VUn^VU(N+1)/2(N-n+1), 其中 n=l,...,N。 实施例一 图 4是根据本发明优选实施例的数据卡温度控制方法的流程图, 是一种 通过调节数据传输速率来控制无线数据卡温度的, 如图 4所示, 该方法的具 体步 4聚如下: 步骤 1 : 对一个或多个器件的温度传感器进行周期釆样。 釆样周期可以 根据实际情况进行设置, 通常设置为 ls〜20s, 不能设置太长, 否则会导致设 备温度控制不及时; 步骤 2: 将釆样温度与设置的门限进行比较; 步骤 3: 控制数据卡传输速率, 当任何一个器件的温度达到或超出其紧 急门限时, 则将数据卡速率调整为 0的命令, 即停止数据传输, 使器件快速 降温,从而避免器件受损或老化; 当任何一个器件的温度高于其高温门限时, 则将数据卡传输速率下调一个等级;当所有器件的温度均低于其低温门限时, 则将数据卡传输速率上调一个等级; 当所有器件的温度小于高温门限且至少 有一个期间的温度高于低温门限时, 则保持数据卡传输速率。 控制速率可以分控制数据卡的上行速率和下行速率, 具体方式为下述的 一种或多种: 1 ) 按照速率集合中的上行速率对数据卡的上行速率进行控制, 不对数 据卡的下行速率进行控制; 2 ) 或按照速率集合中的下行速率对数据卡的下行速率进行控制, 不对 数据卡的上行速率进行控制;
3 ) 按照速率集合中的上下行速率对数据卡的上下行速率同时进行控制。 高温门限与低温门限值可以设置为相同, 也可以设置为不相同。 这里建 议设置为不相同, 低温门限要比高温门限低一些, 这样设置的目的是对温度 变化有一个緩冲作用, 因为如果低温门限和高温门限重叠, 那么当温度降到 低于高温门限时,温度保护模块就会马上给速率控制模块发送速率增加命令, 速率一旦增加, 那么温度就会艮快达到高温门限, 从而导致温度保护模块马 上又启动降速率过程,速率一旦降低, 那么温度就会很快降到低于高温门限, 导致温度保护模块又启动增加速率过程, 如此往复循环, 会导致温度和速率 快速剧烈波动。 而如果氐温门限与高温门限不重叠, 那么速率和温度就不会 那么快速剧烈波动了。 根据本发明的实施例, 提供了一种数据卡, 图 5是根据本发明实施例的 数据卡的结构框图, 如图 5所示, 该数据卡包括: 温度釆集模块 2和温度调 节模块 4 , 下面对上述结果进行详细描述。 温度釆集模块 2, 设置为釆集数据卡中受保护器件的温度; 温度调节模 块 4 , 连接至温度釆集模块 2 , 设置为使用上述温度釆集模块中的结果, 调 节上述数据卡的数据传输速率以控制上述数据卡的温度。 优选地, 图 6是才艮据本发明实施例的数据卡优选的结构框图, 如图 6所 示, 该数据卡还包括如下结构: 温度釆集模块 2包括: 定时单元 21和釆集单元 23 ; 其中, 定时单元 21 , 设置为设定温度釆集的周期; 釆集单元 23 , 设置为根据定时单元 21设定的所述周期釆集数据卡中受 保护器件的温度。 温度调节模块 4包括: 温度保护算法子模块 42和速率控制子模块 44; 其巾, 温度保护算法子模块 42 , 设置为根据釆样温度与设置门限的关系, 输出 速率控制命令; 速率控制子模块 44 ,设置为根据上述速率控制命令控制数据卡中数据传 输速率。 优选地, 温度保护算法子模块 42还包括: 集合设置单元 421、 门限设置 单元 422、 判断单元 423和命令输出单元 424; 其中, 集合设置单元 421 , 设置为设置传输速率集合, 该速率集合
