具体实施方式
为使本申请的目的、技术方案和优点更加清楚明白，下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在一个示例性实施方式中，本申请提供了一种风扇调速系统，图1为本申请提供的一种风扇调速系统的结构示意图。图2为本申请提供的一种网络设备部分架构示意图。如图2所示，风扇调速系统可以集成在任意类型的网络设备中，如交换机设备上。
相应的，如图1和图2所示，本申请提供的风扇调速系统包括：监控板10、信号背板20、至少一个温度传感器阵列30、至少一个风扇集合板40以及至少一个风扇阵列50；监控板10、温度传感器阵列30、风扇集合板40与信号背板20通信连接，风扇集合板40与风扇阵列50通信连接；其中：监控板10或风扇集合板40用于根据温度信息以及预设调速方式计算风扇阵列50的转速，并生成对应的转速控制信息；其中，转速控制信息包括每个风扇的目标转速以及风扇与温度传感器子阵列的对应关系；信号背板20用于传递信息；温度传感器阵列30用于采集网络设备中单板的温度信息；风扇集合板40还用于根据转速控制信息对风扇阵列50中每个风扇的转速进行调整；风扇阵列50用于对网络设备进行散热。
监控板10是网络设备中的风扇控制管理模块，主要用于根据温度传感器阵列30采集的温度信息以及预设调速方式计算风扇阵列50的转速，并生成对应的转速控制信息。可选的，预设调速方式包括但不限于自动独立调速方式、脱机独立调速方式、自动分区调速方式或手动调速方式。其中，自动独立调速方式需要监控板10从温度传感器阵列30顺序 获取到单板上各个位置的温度信息，以及扇阵列50中的风扇的具体位置对应关系，从而动态调整对应位置的风扇转速，其他无关位置的风扇通过调速策略降低到合适的档位。脱机独立调速方式是当监控板10不在位或者监控板10配置到该脱机独立调速方式后，风扇集合板40根据槽位信息自动识别风扇和温度传感器阵列30的对应关系，并直接获取到对应温度传感器的信息以根据对应关系自动调整转速，不需要关心其他温度传感器的信息。自动分区调速方式和手动调速方式为传统控制方式，仅需要从温度传感器阵列30获取的温度信息中筛选得到最高温度和环境温度，然后使用分区的方式整体控制所有风扇调速。除此之外，监控板10还可以监控网络设备中单板的电压或功耗等机电信息，也还可以完成下发风扇控制、上下电控制等功能。监控板10可以与网络设备中的主控板进行通信，以传递机电信息。监控板10可以是专用单板，也可以是拥有相同处理功能的小系统或者是主控板中的一部分功能模块，本申请实施例对此并不进行限制。
信号背板20是一种通讯信号的传输介质，可以用于传递信息。信号背板20可以是电路板，也可以是连接器，还可以是光纤、网线等信号传输介质，本申请实施例并不对信号背板的具体结构进行限定。具体的，信号背板20可以传递监控板10与其他单板之间的机电信息，还可以传递监控板10与风扇集合板40的控制信息。同时，信号背板20还可以通过插在信号背板20的不同位置获取风扇与单板的对应关系。
温度传感器阵列30是单板上的温度采集装置，可以通过多个温度传感器采集到单板不同位置、不同芯片的温度信息。温度传感器阵列30可以是专用的温度传感器芯片，也可以是带有温度测量功能的芯片，本申请实施例对此并不进行限制。通常在网络设备中，每个单板上都配有多个温度传感器，组成多个温度传感器子阵列，温度传感器子阵列通过数据总线传递数据到监控板10或者风扇集合板40。
风扇集合板40是风扇阵列50中风扇转速的控制器，可以接收监控板10发送的转速控制信息以对风扇阵列50中每个风扇的转速进行调整，还可以独立监控单板的温度生成转速控制信息以对风扇阵列50中每个风扇的转速进行调整。其中，转速控制信息可以是控制风扇阵列50调整每个风扇转速的指令信息，具体可以包括但不限于每个风扇的目标转速以及风扇与温度传感器子阵列的对应关系。风扇集合板40可以是一个独立的单板，也可以是包含驱动部分的单板的一部分，本申请实施例对此并不限制。
风扇阵列50可以是多个风机组成的风扇组，用于给网络设备抽风或者吸风散热。风扇阵列50可以采用由多个独立风机拼接而成的多转子风扇，风机的数量可以由温度传感器的密集程度和每个风机的体积决定。
图3为本申请提供的一种风扇对应关系效果示意图，如图3所示，在结构上，单风扇60可以对应一个温度传感器子阵列310，或者多个单风扇60对应一个温度传感器子阵列310，一个风扇集合板40可以同时控制多个风扇，一个风扇集合板40可以对应多个温度传感器子阵列310。
在本申请中，如图1所示，监控板10可以通过信号背板20获取到所有温度传感器阵列30采集到的温度信息，并通过获取的温度信息来计算每个风扇应该配置的转速，从而生成对应的转速控制信息并通过信号背板20下发到风扇集合板40，以使风扇集合板40根据接收的转速控制信息控制驱动风扇的转速。风扇集合板40上配置单独的控制小系统，可以独立获取温度传感器阵列30采集的温度信息，从而生成对应的转速控制信息并控制驱动风扇的转速，可以实现在无监控板10的情况下独立完成风扇转速的控制调节。
综上所述，本申请中的风扇调速系统采用可配置的方式，使得监控板、风扇集合板与温度传感器阵列相互配合，从而实现对风扇阵列的自动调速。通过高密度的温度传感器阵列和风扇阵列实现监控的颗粒度细化，并且把风扇的作用范围控制在较小的水平，从而提高风扇控制效率并降低风扇的噪音水平。由于风扇的数量更多，其作用范围更小，在单个风扇失效时对风扇调速系统造成的影响最小，并且还可以通过相邻风扇来弥补失效风扇损失的风量。另外，当网络设备处于异常状态时，例如温度传感器失效或者监控板失效，风扇调速系统还可以自动切换至风扇集合板进行温度检测和风扇控制，从而最大程度减小部分器件失效造成的影响，提高整机可靠性。
本申请实施例通过风扇调速系统中的温度传感器阵列采集网络设备中单板的温度信息，监控板或风扇集合板根据采集的温度信息以及预设调速方式计算风扇阵列的转速，并生成对应的转速控制信息，并由风扇集合板根据转速控制信息对风扇阵列中每个风扇的转速进行调整，解决了现有网络设备散热系统存在的有效性和可靠性较低等问题，实现了对风扇转速的精细控制和冗余备份，提高了风扇控制效率并降低了噪音水平，从而满足网络设备对散热功耗和噪音的更高需求。

在风扇调速系统采用脱机独立调速方式时，温度传感器阵列的子阵列通过信号背板总线连接到风扇集合板，风扇集合板可以通过该总线获取温度信息。
S320、风扇集合板接收到调速模式后进入主机模式，或，风扇集合板在多次检测没有检测到监控板后进入主机模式。
