本发明的较佳实施方式
本发明的基本思想是: 测量数据传输设备的温度, 再根据测量得到的数 据传输设备的温度控制数据传输设备的数据传输速度, 从而控制数据传输设 备产生的热量, 将数据传输设备的温度控制在预定范围内。
为了使本发明的目的、 技术方案及优点更加清楚明白, 下面结合附图对 本发明的具体实施进行进一步的详细说明。
本发明所述的数据传输设备指用于传输数据的设备, 一般有有线网卡、 调制解调器、 无线网卡等。 与所述数据传输设备进行数据交换的设备一般为 用户使用的数据终端, 也可以为数据传输设备, 为了便于描述这里将与数据 传输设备连接的设备统一称为数据终端。 且将控制数据传输设备温度的系统 简称为温度控制系统。
图 1示出了本发明的控制数据传输设备温度的方法流程。 该方法包括以 下步骤: 步骤 101、 周期性测量数据传输设备的温度。
这里, 可以通过温度感应器等其它的温度测试器周期性地测量数据传输 设备的温度值。 测量周期可以根据用户的需要或数据传输设备的性能来进行 设置, 例如, 可以将测量周期设置在 500m ~ 2000m之间。
步骤 102、 判断温度测量时间点测量得到的温度是否大于预定的温度值, 是则将数据传输设备和数据终端的数据传输速度调小; 否则在确定数据传输 设备和数据终端的数据传输速度小于最大数据传输速度时将数据传输设备和 数据终端的数据传输速度调大。
这里, 预定的温度值可以等于数据传输设备的极限温度值, 也可以小于 数据传输设备的极限温度值。 当数据传输设备的温度超过极限温度值时该数 据传输设备将发生故障, 无法正常工作。
将数据传输设备和数据终端的数据传输速度调小或调大的值的大小与测 量得到的温度值与数据传输设备的极限温度值的差值成正比。 也就是说, 测 量得到的温度值比数据传输设备的极限温度值高越多, 则需要将数据传输速 度调小越多; 测量得到的温度值比数据传输设备的极限温度值低越多, 则越 需要将数据传输速度调大越多。 当然, 将数据传输设备和数据终端的数据传 输速度调小或调大的值的大小还与数据传输设备和数据终端的性能有关。
数据传输速度最大值可以是用户预先根据数据传输设备和数据终端的性 能设置的合适的速度值, 也可以是将数据传输设备和数据终端之间数据包交 互的时间间隔为零时的速度作为数据传输速度最大值。
这里, 数据传输速度是由数据传输量和传输时间决定的, 速度与传输时 间是成反比的,传输时间实际上是传输过程和数据交互所花费的时间的总和。 实际上, 数据传输量设备和数据终端之间数据包交互总是需要一定的时间间 隔的。 4叚设交互时间间隔为零, 即整个数据传输过程花费的时间即为传输过 程所用的时间, 这就把传输时间假设为了一个理论上的最短时间。 因此, 可 将这样设定的速度作为传输速度最大值。
这里, 对数据传输设备和数据终端的数据传输速度进行调整的方式为: 生成将数据传输速度调小的命令并将其发送到数据传输设备及数据终端; 或 者在确定数据传输设备和数据终端的数据传输速度小于最大值时生成将数据 传输速度调大的命令并将其发送到数据传输设备及数据终端; 数据传输设备 或数据终端执行收到的命令, 这样就实现了对数据传输速度的调整。
调大数据终端和数据传输设备进行数据包交互的时间间隔具体为: 数据 终端向数据传输设备发送数据包的时间间隔从 T1调整为 T1+ tl, 数据传输设 备向数据终端发送数据包的时间间隔从 T2调整为 T2+ t3。 调小数据终端和数据传输设备进行数据包交互的时间间隔具体为: 数据 终端向数据传输设备发送数据包的时间间隔从 T1调整为 Tl- 12, 数据传输设 备向数据终端发送数据包的时间间隔从 T2调整为 T2-t4。 其中, Tl、 tl和 t2分别为数据终端在温度测量时间点的数据包发送时间 间隔、数据终端向数据传输设备发送数据包的时间间隔调大的值和调小的值; T2、 t3和 t4分别为数据传输设备在温度测量时间点的数据包发送时间间隔、 数据传输设备向数据终端发送数据包的时间间隔调大的值和调小的值。
温度控制系统向数据终端或数据传输设备发送数据传输速度调整命令可 以通过网络控制信息协议的源端抑制命令定义实现。 温度控制系统向数据终
( 1 )获取从数据终端和数据传输设备之间传递的任意一个分组数据包。
( 2 )分析所获得的分组数据的 IP数据分组头信息。
( 3 )根据网络控制信息协议的源端抑制命令的定义,构造源端抑制命令。
( 4 ) 向数据终端或数据传输设备发送源端抑制命令。
( 5 )丟弃步骤( 1 ) 中获取的分组数据包。
上述源端抑制命令作为调小或调大数据传输速度的命令; 温度控制系统 向数据终端或数据传输设备发送数据传输速度调整命令的过程是一样的。
下面以数据传输设备为网卡, 数据终端为 PC终端为例来进一步说明本 发明的具体实施, 如图 2所示, 控制数据传输设备温度的具体方法包括以下 步骤:

步骤 202、 PC终端发起搜网请求,搜索到网络后, PC终端与网卡建立网 络连接。
PC终端与网卡建立网络连接时用到网络连接管理应用程序,通过调用网 络连接管理动态链接库提供的方法, 提供给固件搜网的中心频率、 带宽及列 表, 向固件发出搜网请求。 固件根据请求的中心频率、 带宽和开始搜索基站, 最后, 固件向动态链接库发出响应, 将搜索到的中心频率、 基站 ID、 带宽、 信号强度、 信噪比等参数传给动态链接库。 动态链接库则将搜网结果传给应 用程序。
应用程序将需要请求的中心频率、 带宽、基站 ID等参数, 传给网络连接 管理动态链接库, 发出上行同步请求, 动态链接库将该上行同步请求发送给 网卡固件。 固件根据请求, 将设备同步到指定的基站。 并向动态链接库返回 上行同步响应, 使得动态链接库得到同步的结果, 如果同步成功, 则响应包 括同步上的基站的中心频率、 基站 ID、 带宽、 信号强度、 信噪比等参数值。 动态链接库最终将响应传给应用程序。 完成整个接入网络的过程。
步骤 203、 判断测量周期是否到达, 是则执行下一步骤; 否则继续等待, 直到测量周期到。
测量周期可以由用户预先设置, 在周期到达时, 温度控制系统开始执行 步骤 204。
步骤 204、 在温度测量时间点 获取网卡温度。
这里, 温度控制系统可以通过温度感应器或其它温度传感装置获取网卡 当前的温度。
步骤 205、 判断网卡温度值是否大于预定的温度值, 是则执行步骤 208, 否则执行步骤 206。 温度控制系统判断获取的网卡的温度是否大于预定的温度值, 是则执行 步骤 208, 否则执行步骤 206.
步骤 206、 网卡将存入预留緩存区的部分数据释放。
温度控制系统指示网卡将预留緩存区的部分数据释放出来, 供下一步骤 进行发送。
步骤 207、 分别减小 P C终端发送数据包的时间间隔和网卡发送数据包 的时间间隔后返回步骤 203。
将数据终端向数据传输设备发送数据包的发送时间之间的间隔调小一预 定值; 将数据传输设备向数据终端发送数据包的发生时间间隔调小另一预定 值。 然后返回到步骤 203 , 完成本测量周期内对网卡的数据传输速度的调整。
步骤 208、 网卡向 PC终端发送源端抑制命令, 并将接收到的接入网发送 的部分数据存入预留緩存区。
温度控制系统指示网卡向 PC终端发送源端抑制命令, 并将接收到的接 入网发送的部分数据存入预留緩存区, 以避免数据丟失。
步骤 209、分别增加 PC发送数据包的时间间隔和网卡发送数据包的时间 间隔后返回步骤 203。
