背景技术
目前市面上的交换机从有没有管理功能来分类，主要有两类：
一类是管理型的交换机，可以通过联网的方式来进行远程管理；这类交换机管理功能强大，可通过WEB页面、串口等方式对交换机进行管理，但必须使用电脑与之连接，才能达到管理交换机的目的。
另一类是无管理功能的非管理型交换机，俗称“傻瓜”交换机。这类交换机不能根据使用环境优化交换机的运行参数，在长期的使用过程中容易出现软故障。
但是此两类交换机各有各的缺点，具体如下：
管理型交换机
1.管理型交换机功能强大，应用灵活，但需要配置，操作比较复杂，对操作人员的技能要求较高。
2.为了对交换机进行管理，通常是需要通过串口、网口等方式与PC机连接起来，并使用PC机的终端软件来对PoE交换机的一些参数进行设置。
3.比非管理型交换机的成本贵。
非管理型交换机
1.工厂在设计机器时，把常规的参数固化在机器中，不能根据使用环境优化和更改机器的参数。
2.在机器设置一些开关，用来更改某些参数，但由于开关需要占用机器 面板的空间，不能设置的太多，这种方式只能布置少量的开关。

具体实施方式
下面结合附图对本发明一种基于本地管理的PoE交换机的技术方案作进一步详述：
见图1、图2所示，一种基于本地管理的PoE交换机，包括监控MCU模块、电源系统模块、显示模块、PoE系统模块、交换机系统模块、按键模块，监控MCU模块通过总线分别与显示模块、PoE系统模块、交换机系统模块相连接，监控MCU模块实时监测所述PoE系统模块、交换机系统模块的工作状态，通过所述显示模块显示出相关信息，监控MCU模块通过总线与按键模块相连接，按键模块通过显示模块把信息传递给所述监控MCU模块，所述监控MCU模块根据收到的信息做出相应操作。在PoE交换机的机壳1上设有端口2，LCD显示屏3及按键组4。显示模块为一LCD显示屏3，LCD显示屏3设置于机壳上1，按键模块为一组按键组4并置于机壳上1，其中按键组4设置于所述LCD显示屏3的四周。按键组4包括菜单键、上键、下键、确认键、返回键。
一种基于本地管理的PoE交换机的管理系统的实现方法工作过程如图3、图4所示如下：
基于本地管理的PoE交换机的人机交互功能管理系统的实现方法由监控MCU模块、显示模块和按键模块组成。
当电源系统模块给各模块供电之后，监控MCU模块开始工作，初始化各功能模块。初始化完成之后显示模块发指令给LCD显示屏显示公司Logo 5秒钟，之后再显示端口信息，监控MCU模块通过I/O总线实时访问按键模块，实时监测是否收到按键指令，如果有收到按键指令，则处理按键指令，处理完成之后，命令显示模块显示端口信息状态。
若未收到按键指令，监控MCU模块读取PoE系统模块信息，获取端口的状态，首先检测PoE系统模块是否正常，不正常则复位PoE系统模块，然后继续检测PoE系统模块。如果PoE系统模块正常则初始化PoE系统模块，然后检测电源电压是否正常，电源电压不正常则报警，并实时检控电源电压。如果电源电压正常，检测控制芯片温度是否正常，控制芯片温度不正常则报警，并实时检控制芯片温度。做完上述工作之后检测端口是否连接有PD，如果连接了PD,则检测端口是否存在轻载、过载或短路情况，如果端口不存在轻载、过载或短路则读取端口输出功率并在LCD显示屏上显示出来并实时检测。如果端口存在轻载、过载或短路现象，则报警并实时检测，并且PoE系统模块通过复位等一系列的操作来排除异常，如果异常排除了，则在LCD显示屏上显示出端口信息，未排除则继续运行排队异常指令。若端口上没有连接PD，则实时检测该端口的电源电压，控制芯片温度。
端口不存在轻载、过载或短路之后，监控MCU模块开始检测交换机系统模块，交换机系统模块实时检测各端口宽带是否存在异常，如果存在异常，则对相应端口的PD断电复位，复位后检测是否消除了该异常，若还有异常，则继续复位，并检测复位次数，若未超过10则继续复位，如果复位超过10次则直 接关闭该端口电压。若各端口宽带不存在异常，监控MCU模块通过总线访问交换机系统模块，分别获取端口上传和下传的数据量，计算出端口的上传和下传的数据带宽是多少，在LCD显示屏上显示出来。
实施例一：参见图5，PoE交换机正常工作时LCD显示的内容。
第五列：端口号；
第六列：对应端口的PoE信息；
16.5W：表示从PoE交换机的端口正在输出的功率；
OLP：表示PSE对应的端口过载，端口停止供电；
ULP：表示PSE对应的端口轻载，端口停止供电；(*当网线上的电流小于7.5mA时，PSE认为PD已经拨掉，端口停止供电)
SCP：表示PSE对应的端口出现短路的现象，端口停止供电；
OFF：白色和绿色的OFF表示通过菜单命令把端口禁止了；红色的OFF表示该端口的数据速率超过了设定的值，并且在1小时内，出现了10次，为了保护系统正常工作，关闭了该端口的供电；
----W：表示该端口没有PD设备接入。
第三、七列：对应的端口进入交换机的数据速率；
第四、八列：对应的端口从交换机出去的数据速；
---M：表示该端口没有数据传输；
<1M：表示该端口的数据传输速率小于1M；
856M：白色和绿色的字符表示数据正在传输的速率；红色字符表示该端口的数据传输速率大于交换机带宽设定的值，会引起PSE重启该端口的供电，如果在1个小时内，重启10次，还出现这个现象，将关闭该端口的供电；
PB：表示PoE交换机对外输出的最大电源功率；
TP：表示PoE交换机通过端口已经输出的电源功率；(TP的值小于PB的值)。
