图 1为一种常见的单板运行状态的指示方式示意图;
图 2为本发明中检测装置结构示意图;
图 3为本发明中具体实施例一中按钮所在位置示意图;
图 4为本发明中具体实施例一中检测装置结构示意图;
图 5为本发明中具体实施例二中检测装置结构示意图。 具体实施方式
本发明中,通过向各单板上的可编程逻辑单元( CPLD )发送检测指令, 来检测各单板上的指示装置是否正常, 即 CPLD收到检测指令后, 如果能 够驱动单板上的指示装置发出指示, 则表明相应指示装置正常; 如果不能 驱动单板上的指示装置发出指示, 则表明相应指示装置故障。
图 2为本发明中检测装置结构示意图, 如图 2所示, 该装置包括: 检 测单元、 控制单元和指示装置, 其中, 检测单元用于向控制单元发送检测 指令; 控制单元用于根据收到的检测指令驱动指示装置发出指示。 指示装 置正常时, 将在控制单元的驱动下发出指示, 因此, 如果能够驱动单板上 的指示装置发出指示, 则表明相应指示装置正常; 如果不能驱动单板上的 指示装置发出指示, 则表明相应指示装置故障。 控制单元和指示装置均在 单板上。
以上所述指示装置可以为通过发光进行指示的指示灯, 如 LED; 也可 以为通过声音进行指示的声音指示装置。 下面以指示灯为例对本发明的具 体实现进行描述。
本发明方案中, 可以在通信设备上设置一个按钮, 通过按下该按钮实 现检测命指令的发送。 具体地, 利用通信设备原有的系统背板、 主控板及 各功能板上的 CPU和 CPLD,通过设置的按钮实现对单板上指示灯的控制。 这样的实现方式无需对原有通信设备做出很大改动, 只需简单改进即可实 现, 成本低廉, 操作方便。
按钮设置于主控板时, 如图 3 所示。 在实际使用中, 设置按钮的位置 并不仅限于在主控板上, 也可以在通信设备上启用的某一功能板上设置按 钮, 只要该按钮所连接的线路能够与系统背板上的控制总线相连即可。
图 4为本发明中具体实施例一中检测装置结构示意图, 如图 4所示, 检测单元包括: 按钮和系统背板上的控制总线, 控制单元为各单板上的 CPLD, 其中, 按钮用于接收维护人员的操作, 按钮被按下时, 用于使系统 背板上的控制总线低电平; CPLD用于检测到系统背板上的控制总线低电平 时, 驱动自身所在单板上的指示灯点亮。 这里, 按钮被按下相当于通过系 统背板向 CPLD发送检测指令。
结合图 4的结构, 具体实现过程包括:
所有单板的 CPLD均通过控制线连接到系统背板的控制总线上。 由于 系统背板上的控制总线上有上拉电阻存在, 因此, 该控制总线处于高电平 状态。 各单板上的 CPLD通过控制线检测到系统背板上的控制总线高电平 时, CPLD根据单板的 CPU发出的状态指令确定单板当前的工作状态, 按 照预先设定的、 对应于该工作状态的显示规则, 驱动指示灯闪烁、 或常亮、 或常灭显示等。
指示灯不亮, 维护人员需要进行维护时, 可以通过按下该按钮来直接 使 CPLD驱动各单板上的指示灯都点亮。 按下按钮时, 按钮一端与系统背 板的控制总线连接, 另一端接地, 使得系统背板的控制总线直接接地, 变 为低电平。 单板上的 CPLD检测到系统背板的控制总线低电平时, 驱动该 单板上的指示灯点亮。 如果此时有指示灯仍然不亮, 则表明相应指示灯硬 件损坏, 需要更换; 如果此时所有指示灯都点亮, 则表明各单板上的指示 灯是正常的, 当前是相关单板发生故障, 如软件故障或其他原因, 需要进 行进一步定位以排除故障。 放开按钮后, 系统背板的控制总线重新变为高 态, 按照预先设定的、 对应于该工作状态的显示规则, 驱动指示灯闪烁、 或常亮、 或常灭显示等。
通常, 通信设备都由网管系统来进行管理, 对于放置位置较高等不方 便按下按钮的设备, 本发明中可以在网管系统中增加指示灯检测的功能, 当需要测试指示灯时, 由网管系统向主控板下发检测指令。 主控板收到检 测指令后, 向所有功能板转发该检测指令。 主控板及各功能板收到检测指 令后, 控制 CPLD驱动指示灯点亮。 网管系统通过主控板下发检测取消指 令后, 各指示灯恢复正常状态。
图 5为本发明中具体实施例二中检测装置结构示意图, 如图 5所示, 检测单元包括: 网管系统和主控板上的 CPU, 控制单元为各单板上的 CPU 和 CPLD, 其中, 网管系统用于向主控板上的 CPU发送检测指令; 主控板 上的 CPU用于向各功能板上的 CPU转发收到的检测指令;各单板上的 CPU 用于收到检测指令后,触发自身所在单板上的 CPLD驱动指示灯点亮; CPLD 用于根据触发驱动自身所在单板上的指示灯点亮。 以上所述各单板上的 CPU可以包括主控板上的 CPU和各功能板上的 CPU。
结合图 5的结构, 具体实现过程包括:
正常情况下, CPLD根据单板的 CPU发出的状态指令确定单板当前的 工作状态, 按照预先设定的、 对应于该工作状态的显示规则, 驱动指示灯 闪烁、 或常亮、 或常灭显示等。
维护人员需要进行维护检测指示灯时, 维护人员通过网管系统的图形 用户界面(GUI, Graphical User Interface )下发检测指令, 该检测指令的命 令参数是包括所有单板。 通信设备的主控板上的 CPU收到检测指令后, 向 所有功能板上的 CPU转发该检测指令。 各单板上的 CPU收到检测指令后, 下发指令控制各单板上的 CPLD驱动指示灯点亮。 如果此时有指示灯仍然 不亮, 则表明相应指示灯硬件损坏, 需要更换; 如果此时所有指示灯都点 亮, 则表明各单板上的指示灯是正常的。
维护完成后, 维护人员再通过网管系统的 GUI下发检测取消指令, 通 信设备的主控板上的 CPU 收到检测取消指令后, 向所有功能板上的 CPU 转发该检测取消指令。 各单板上的 CPU收到检测取消指令后, 各单板 CPU 控制 CPLD驱动指示灯进行指示灯的正常显示, 即 CPLD继续根据单板的 CPU发出的状态指令确定单板当前的工作状态, 按照预先设定的、 对应于 该工作状态的显示规则, 驱动指示灯闪烁、 或常亮、 或常灭显示等。
以上所述功能板是指通信设备上正在启用的功能板。
以上所述, 仅为本发明的较佳实施例而已, 并非用于限定本发明的保 护范围。
