具体实施方式
此处描述的称作系统数据捕获的方法和装置，描述了用于数据捕获系统收集的数据的有条件记录，显示或处理的装置。在一个实施例中，该方法以实时数据捕获模式运行。在另一个实施例中，该方法还应用于非实时系统中。当与断路器控制和保护系统一起使用时，系统数据捕获使得系统数据进行离线分析。另外，系统数据捕获有助于从整个系统收集的数据分析，如，电流和电压测量，以及断路器状态，从而有助于识别多种故障类型，并且在合理故障和损坏性跳闸之间进行区分。
图1示出了例如由工业企业使用的配电系统10的代表性示意图。在代表性实施例中，系统10包括至少一个主馈电系统12，配电总线14，多个电力电路开关或断流器，这里也称作断路器(CB)16，以及至少一个负载18，该负载例如但不局限于电动机，焊接机，计算机，加热器，照明设备，和/或其他电气设备。
使用中，将电力从能源(未示出)供给主馈电系统12，即，例如开关板。该能源诸如但并不局限于从例如核反应堆，烧煤锅炉，燃气轮发电机以及柴油发电机获得动力的蒸汽涡轮机。供给主馈电系统12的电力使用断路器16分成多个支路，断路器16将电力提供给工业企业中的各种负载18上。另外，在各支路中提供断路器16以有助于保护设备，即，负载18，该负载18连接在各支路中。此外，这是因为可将特殊负载18通电或者断电而不影响其他负载18，因此断路器16有助于使设备故障达到最小，从而增加效率，以及减小操作和制造成本。
配电系统10包括断路器控制保护系统19，控制保护系统19包括多个节点电子单元20，并且每个节点电子单元20电连接到数字网络22上。断路器控制保护系统19还包括至少一个中央控制处理单元(CCPU)24，该中央控制处理单元24通过开关23电连接到数字网络22上，该开关23例如但并不局限于以太网(Ethernet)开关23。在使用中，每个单独的节点电子单元20电连接到各自的断路器16上，这样CCPU24通过数字网络22并通过相应的节点电子单元20电连接到每个断路器16上。
在代表性实施例中，数字网络22为快速以太网(Fast Ethernet)协议网络。在另一实施例中，数字网络22包括，例如，至少一个局域网(LAN)或广域网(WAN)，拨号连接(dial-in-connection)，电缆调制解调器，以及专用高速ISDN线。数字网络22还包括能互连到Internet上的任何设备，这些设备包括基于网络的电话机，个人数字助理(PDA)，或其他基于网络的连接设备。值得注意的是数字网络22网络可基于IEEE 802.3(u)及其后继标准(successor)的未来修改进行升级。还应该注意的是数字网络22构造成例如星形拓扑。
在一个实施例中，CCPU24是计算机，并包括设备26，例如软盘驱动器或者CD-ROM驱动器，从而有助于读取来自计算机可读媒介28的指令和/或数据，计算机可读媒介28如软盘或CD-ROM。在另一个实施例中，CCPU24执行存储在固件(未示出)中的指令。将CCPU24进行编程以实现在此描述的功能，但其他可编程电路可同样进行编程。因此，如此处所使用的，术语计算机并不局限于现有技术中称作计算机的那些集成电路，而是广泛地指计算机，处理器，微控制器，微机，可编程逻辑控制器，专用集成电路及其他可编程电路。另外，尽管描述在配电设备中，也可考虑本发明对包括工业系统的所有配电系统产生有益之处，例如，但不局限于安装在办公楼中的配电系统。
图2是示出了与配电系统10(示于图1)并尤其与断路器控制保护系统19(示于图1)使用的节点配电系统29的代表性示意图。节点配电系统29包括电源30，该电源30通过节点配电总线32电连接到节点电子单元20上。在代表性实施例中，电源30是不间断电源(UPS)。在一个实施例中，电源30接收来自配电系统10的电能并且然后将该电能通过节点配电总线32分配给节点电子单元20。在可替换实施例中，不将电能供给电源30，而是，电源30采用内部电源将电能提供给节点电子单元20，该内部电源例如但不局限于多个电池(未示出)。在另一个可替换实施例中，节点电子单元20由从电流传感器82和/或电压传感器84得到的二次电流提供电能。在该实施例中，断路器控制保护系统19不包括节点配电系统29，电源30或节点配电总线32。
图3是CCPU24的代表性示意图。CCPU24包括至少一个存储器装置40，该存储器装置例如但不局限于只读存储器(ROM)42，快速存储器44，和/或随机存取存储器(RAM)46。CCPU24还包括中央处理器单元(CPU)48，该中央处理器单元48电连接到至少一个存储器装置40上，还连接到内部总线50，通信接口52以及通信处理器54上。在代表性实施例中，CCPU24是印刷电路板，并且包括电源56，从而提供电能给印刷电路板上的多个设备。
此外，在代表性实施例中，内部总线50包括地址总线，数据总线，以及控制总线。在使用中，地址总线构造成使CPU48对多个内部存储器位置或输入/输出接口进行访问，该输入/输出接口例如但不局限于通过通信处理器54的通信接口52，以及通过网关处理器58的网关接口57。该数据总线构造成在CPU48和至少一个输入/输出之间发送指令和/或数据，并且控制总线构造成在多个设备之间发送信号从而有助于确保这些设备同步运行。在代表性实施例中，内部总线50是双向总线，这样使得信号可在内部总线50上的任何一个方向上发送。CCPU24还包括至少一个存储装置60，存储装置60构造成存储多个通过内部总线50发送的信息。
在使用中，网关接口57通过互联网链接62或内联网62与远程工作站(未示出)进行通信。在代表性实施例中，远程工作站是包括网络浏览器的个人计算机。尽管描述了单个工作站，此处描述的这种功能可在与网关接口57连接的多台个人计算机的一台上实现。例如，网关接口57可通信连接到各种单机上并连接到第三方上，单机包括本地操作机，第三方如通过ISP互联网连接的远程系统操作机。在该代表性实施例中的通信示出为通过互联网实现，然而，任何其他广域网(WAN)型的通信可在其他实施例中使用，其他实施例即，系统和方法不限于通过互联网实现。在一个实施例中，信息在网关接口57上接收并通过CCPU24和数字网络22发送给节点电子单元20。在另一个实施例中，从节点电子单元20发送的信息在通信接口52上接收并通过网关接口57发送给互联网62。
图4是单个节点电子单元20的代表性示意图。在该代表性实施例中，节点电子单元20是远离CCPU24和断路器16安装的单一设备。在代表性实施例中，节点电子单元20与断路器16隔开，但靠近断路器16。在代表性实施例中，节点电子单元20是印刷电路板。
在一个实施例中，节点电子单元20接收从多个设备输入的信号，这些设备例如但并不局限于电流传感器82，电压传感器84，和/或断路器16。来自断路器16的状态信号包括与断路器的一个或多个状态相关的信号，例如但并不局限于辅助开关状态，以及弹簧装载开关状态。另外，节点电子单元20至少发送信号给断路器16以便控制断路器的一个或多个状态。
在使用中，信号通过节点电子单元20发送到CCPU24和数字网络22上。节点电子单元20接收该信号并将数字消息打包，该数字消息包括信号和与节点电子单元20的质量(health)和状态相关的附加数据。该质量和状态数据可包括信息，该信息基于由内部诊断程序发现的问题和自测程序的状态，自测程序在节点电子单元20内本地运行。CCPU24使用一个或多个保护算法，监测算法以及其任意组合处理数字消息。响应数字消息的处理，CCPU24通过数字网络22将数字消息返还给节点电子单元20。在代表性实施例中，节点电子单元20通过响应从CCPU24接收的数字消息的信号来激励断路器16。在一个实施例中，响应仅由CCPU24发送的命令来激励断路器16，即，断路器16不受节点电子单元20本地控制，而是基于从网络22上的节点电子单元20接收的数字消息从CCPU24远程操作。
图5是电连接到节点电子单元20上的断路器16的代表性示意图。在该代表性实施例中，断路器16包括开关组件，该开关组件包括可动和/或固定触头，抑弧装置，以及跳闸和操作机构。断路器16仅包括一个跳闸线圈100，闭合线圈102，辅助开关104，弹簧装载开关106，以及电动机108。断路器16不包括跳闸单元。断路器16的各种元件(如，跳闸线圈100，闭合线圈102，辅助开关104，弹簧装载开关106，电动机108)可由节点电子单元20提供电能。可替换地，断路器16可由从电流传感器82和/或电压传感器84得到的二次电流提供电能。
断路器16与节点电子单元20通过线束电气通信，其中该线束可包括铜导线，通信管道，及其任一组合。电流传感器82，以及电压传感器84与节点电子单元20通过电缆进行电气通信，该电缆可包括铜导线，通信管道，及其任一组合。在代表性实施例中，断路器16是靠近节点电子单元20，电流传感器82，以及电压传感器84安装的单一设备。
在使用中，将来自节点电子单元20的激励信号发送给断路器16，从而激励断路器16中的多个功能，例如，但并不局限于，操作跳闸线圈100，操作闭合线圈102，以及影响断路器闭锁特征。辅助开关104和操作弹簧装载开关106提供断路器参数的状态指示给节点电子单元20。电动机108构造成对工作弹簧进行再装载，当断路器16闭合后构造成为闭合弹簧(未示出)。值得注意的是电动机108可包括，例如，弹簧装载开关，能对跳闸弹簧进行再装载的螺线管和其他任一种电子-机械装置。为了闭合断路器16，闭合线圈102由来自激励电源模块(未示出)的关断信号通电。闭合线圈102激励闭合机构(未示出)，该闭合机构将至少一个可动电气触头(未示出)连接到相应的固定电气触头(未示出)上。断路器16的闭合机构锁定在闭合位置，这样使得当闭合线圈102断电时断路器16保持闭合。当断路器16闭合时，辅助开关104的“a”触头也将闭合并且辅助开关104的“b”触头将打开。“a”和“b”触头的位置由节点电子单元20进行检测。为了打开断路器16，节点电子单元20向跳闸线圈(TC)100通电。TC100直接作用于断路器16上以释放保持断路器16闭合的锁定机构。当锁定机构释放时，断路器16将打开，打开辅助开关104的“a”触头并闭合辅助开关104的“b”触头。然后跳闸线圈100由节点电子单元20断电。在断路器16打开后，与由电动机108进行再装载的闭合弹簧一起，断路器16为下一个工作周期作准备。在代表性实施例中，每个节点电子单元20以一对一的对应关系连接到断路器16上。例如，每个节点电子单元20仅与一个断路器16直接通信。在可替换实施例中，节点电子单元20可与多个断路器16进行通信。
图6是示于图1的配电系统10的网络部分600的简化框图。与图1所示的元件相同的图6中的元件在图6中采用与图1中相同的附图标记进行标记。因此，配电系统10的网络部分600包括多个节点电子单元20，每个节点电子单元20通过专门用于每个网络22的通信接口602通信连接到双冗余网络22上。在代表性实施例中，网络22是双冗余的。在可替换实施例中，网络22可冗余到由用户的需要所预定的水平上。每个网络22通信连接到网络开关23上，该网络开关通信连接到每个CCPU24上。每个CCPU24通信连接到硬件时钟604上。在代表性实施例中，每个CCPU24的并行端口用于接收来自硬件时钟604的输出信号。硬件时钟604可冗余到由用户的需要所预定的水平上。
在操作上，硬件时钟604发送输出信号给所有的CCPU24，这些信号包括在正则区间上的中断脉冲。指定每个中断脉冲一个序号。在代表性实施例中，序号为16位长。在另一个实施例中，序号可在4位长和64位长之间。将每个中断脉冲和序号发送给每个CCPU24并行端口上，这样使得每个中断可由其单独的序号来连续识别。在每个中断脉冲上，硬件时钟604将序号递增从而使得新的连续的序号与每个接着产生的中断脉冲一起发送。当处理器48接收中断脉冲时，处理器48根据其程序指令服务于中断。在代表性实施例中，处理器48发送交叉基准(transreference)信号给网络22上所有的节点电子单元20，该交叉基准信号包括基准序号。为了保持基准号，处理器48在每次接收来自时钟604的输出信号时递增内部64位寄存器。
另外，处理器48检测误差的引入中断脉冲。处理器48估计将要接收的下一个中断脉冲的时间。在代表性实施例中，监视定时器用于估计下一个输入信号或中断脉冲的期望时间。如果中断脉冲在期望时窗内接收，处理器48采用脉冲从而将它本身的时钟与硬件时钟604脉冲同步。如果中断脉冲在期望时窗之外，处理器48确定中断脉冲是否丢失，该丢失意味着中断脉冲没有由处理器48接收。脉冲的断续或不可靠接收可显示硬件时钟604和/或互连电缆的老化，并且可导致CCPU24和节点电子单元20失步。当中断脉冲丢失时，处理器48通过采用其内部时钟以确定丢失的中断脉冲的个数并由已经确定丢失的脉冲的个数递增基准号来试图恢复该基准号。通过这种方法，基准号保持与开始点相关的合适时间递增，该开始点与其他计时系统一致。在代表性实施例中，配电系统10事件可与采用该基准号的公用事业公司信号源一致。当处理器48确定硬件时钟406的中断脉冲故障，可采用稳定脉冲的可替换信号源。在代表性实施例中，当硬件时钟604故障时，处理器604时钟用作提供中断脉冲。在可替换实施例中，与网络22连接的一个CCPU24可互连到每个其他的处理器48上，从而当硬件时钟604故障时提供稳定脉冲的可替换信号源。
节点电子单元20通过网络22接收来自CCPU24的交叉基准信号。每个节点电子单元20接收来自每个CCPU24的交叉基准信号。在代表性实施例中，网络22为双冗余，同样地，每个节点电子单元20接收包括辨别序号的两个交叉基准信号。为了将来自与节点电子单元20相关的多个传感器的数据的采集进行恰当的同步，节点电子单元20使用校正器功能程序以将它的时钟与引入的交叉基准信号同步。在一个实施例中，节点电子单元20误差检测期望定时输入的交叉基准信号。如果连接到网络的任何一个CCPU24正在发送期望时窗外的交叉基准信号，该CCPU24将作为潜在故障进行标记，并且将忽略来自该CCPU24的交叉基准信号。如果所有的CCPU24正在发送处于期望时窗内的交叉基准信号，节点电子单元20确定校正器程序以将节点电子单元20的时钟与CCPU24的时钟同步。在代表性实施例中，节点电子单元20采用将节点电子单元的时钟与其时钟同步的预定优选CCPU24。只要优选CCPU24发送在期望时窗内的交叉基准信号，节点电子单元20将使其时钟与该优先CCPU时钟同步。如果主CCPU24时钟发送期望时窗外的交叉基准信号，基于优先权的顺序，节点电子单元20可转换到与预定CCPU24同步，直到该优选CCPU24返回到发送在期望时窗内的交叉基准信号为止。在可替换实施例中，节点电子单元20将接收来自每个CCPU24的对应交叉基准信号的时间进行平均，并使其时钟与该平均值同步。注意，节点电子单元20采用与软件锁相环结合的交叉基准信号以调节节点电子单元时钟与CCPU24同步。
图7是硬件时钟604的代表性实施例的示意框图，该硬件时钟使用在图6所示的配电系统10的网络部分600中。在代表性实施例中，硬件时钟604包括晶体振荡器606，该晶体振荡器电连接到分频器电路608上。分频器电路608的输出连接到现场可编程门阵列(FPGA)装置610的输入上。FPGA610的输出连接到三态缓冲器612上。缓冲器612的输出连接到并行端口总线上，该并行端口总线连接到与配电系统10连接的每个CCPU24的并行端口上。
在使用中，FPGA608用作将从晶体振荡器606得到的时钟脉冲分成中断信号的期望频率。在代表性实施例中，晶体振荡器606工作在近1.832MHz的频率上。分频器608将振荡器606的频率向下分成近4.0kHz。FPGA608也用作得到8或16位的序号。在代表性实施例中，中断信号，低/高字节信号，以及2×8位序号(一次给1个字节的16位值)由所有CCPU24的并行端口读取。
图8是示出了用于同步图6所示的多台冗余计算机的代表性过程的流程图800。在配电系统10上运行的每个CCPU24通过它的每个并行端口从硬件时钟604接收802中断脉冲流。尽管中断脉冲描述为通过每个并行接口由每个CCPU24接收，但是每个CCPU24可通过任何一个方便的端口和/或硬件时钟604的硬件连接接收中断脉冲。CCPU24还接收804与每个脉冲相关的序号。该序号由硬件时钟604产生。在代表性实施例中，序号为在8位总线上以两个字节发送给所有的CCPU24的16位号。
每个中断脉冲使得每个CCPU处理器48读取由硬件时钟604提供的序号。该中断脉冲由处理器48用于控制所有内部计算的执行时钟。当接收每个中断时，处理器48发送804包括序号的输入信号给基准目标，该基准目标递增计算所接收的每个中断脉冲的内部基准号计数器并允许通过变换806输入信号到公知的时间基准而重建并与外部系统的数据一致。处理器48产生多点传送消息，该多点传送消息是通过网络22发送给所有的节点电子单元20的广播通信。每个消息包括交叉基准信号和与该脉冲相关的序号。
在网络22上运行的每个节点电子单元20接收来自网络22上运行的每个CCPU24的多点传送消息。每个节点电子单元20使用预定程序以判断出消息定时之间的任何区别。在一个实施例中，节点电子单元20将一个CCPU24认为是优选的，并且节点电子单元20使用来自该CCPU24的交叉基准信号和序号，直到节点电子单元20确定该CCPU24是不可靠的。在另一个实施例中，节点电子单元20可使用平均技术或表决技术来确定哪个CCPU交叉基准信号为所使用的最正确的脉冲。
节点电子单元20采用交叉基准信号和序号将来自每个传感器的收集数据进行同步，从而采样传感器和内部电子元件寄存器，使得配电系统10的状态可在CCPU24中精确重建。在大配电系统10中，每个节点电子单元20可在不同的实时采样传感器和数据寄存器，这是因为在节点电子单元20之间系统中固有时间滞后。采样许多电气参数将产生不精确的结果，但当每一个所采样的参数与交叉基准信号和序号相关时，CCPU24可解决当每个采样进行时实时上的改变，其中电气参数相对甚至很小区别的实时上的时间经常改变。
节点电子单元20包括软件锁相环，该软件锁相环使用广播消息、交叉基准信号和序号，从而将其时钟与CCPU时钟同步。
每个CCPU24进行编程，以实现输入的中断脉冲的误差检测。每个CCPU处理器48确定何时期望从硬件时钟604到达的下一个中断信号的估计时窗。如果下一个中断脉冲在期望窗内接收，处理器48假定硬件时钟604和互连电缆正在正确运行，不进行校正行为。如果至少一个中断脉冲在期望窗外到达，处理器48执行确定校正行为的误差处理程序，从而保持配电系统10同步。在代表性实施例中，处理器48在激励该误差处理程序之前等待四个丢失的脉冲。在另一个实施例中，周期处理器48等待从零丢失脉冲(处理器唯一地采用脉冲的可替换信号源)到最大数量所配置的用户，最大数量显示处理器48从不使用脉冲的可替换信号源。在一个实施例中，当检测中断脉冲已经停止到达时，切换到中断脉冲的可替换信号源，如处理器时钟，可替换CCPU处理器时钟，或另一个可替换脉冲源。处理器48然后估计多少个脉冲丢失并递增基准号寄存器，通过该基准号从而将该基准号寄存器返回到尽可能接近其恰当时刻。当中断脉冲恢复时，处理器48执行程序从而恢复同步到硬件时钟604。
图9是示出了过程900的代表性实施例的数据流程图，该过程用于同步图6所示的多台冗余计算机。依据预定的需求，多个CCPU24可包括在配电系统10中。每个CCPU24包括类似的数据结构，但仅仅是包括在一个CCPU中的数据结构在此进行描述。另外，类似的数据流程图在每个节点电子单元20中实施，数据流程图以此处描述的类似方式运行。CCPU24从外部定时源904接收外部输入定时信号902，该外部定时源904位于远离CCPU24的地方。此处使用的定时信号指的是定时时钟脉冲以及信号，该信号的到达显示定时事件并且包括消息中的定时部分。例如，定时信号可为64位长的消息，该64位长包括显示序号的第一组位，以及显示相关时间戳(timestamp)的第二组位。接收定时信号的元件或数据结构可记录接收定时信号的本地时间，分析定时信号内的信息，以及基于在定时信号中接收的定时信息来鉴别它本身的时钟运行。另外，元件或数据结构可从多个信号源接收多个定时信号，并使用一个算法来确定它本身的时钟或其它接收输入信号的时钟的质量及状态。在代表性实施例中，外部定时源904可包括硬件时钟，另一个CCPU24，以及系统10外部的辅助电源，在硬件时钟中输入信号902可包括6位长到16位长的序号。
CCPU24还接收来自内部定时源908的内部定时信号906，该内部定时源位于CCPU24内部，例如，但不局限于处理器时钟。至少一个选择器910的每一个接收输入定时信号902和906，以及多个选择参数912。选择参数912由选择器910使用，以确定输入信号902和906的哪个用作产生输出信号的原始信号源。在代表性实施例中，选择参数912可用于确定电源904和908的优先顺序，以及所使用的标准，该标准用于确定期望时窗内的输入信号902和906的存在，确定输入信号902和906的丢失，确定无效输入信号902和906，以及确定噪声输入信号902和906。为了确定期望时窗，选择器910可采用监视定时器。如果选择器910确定输入信号902和906中的一个不满足由选择参数912所指示的标准，选择器910可产生并发送校正发生器信号916，该信号916输入到校正器函数918中。校正器函数918基于校正发生器信号916和输入信号k922确定定时误差信号920。输入信号k922与选择参数912相关，使得选择器910和校正器函数918协调运行。误差信号920发送到信号源902和906中与输入信号误差相关的单独一个信号源上。每个单独的信号源902和906基于误差信号920调节其单独的输入信号。
输入信号902和906还由基准目标924进行接收，该基准目标基于输入信号902和906以及内部算法将输入信号902和906转换为基准信号，该内部算法将基准维持在绝对时间上。例如，输入信号902和906可包括6位长的序号。每一个输入信号902和906可在例如200和60微秒的周期到达。随着每个输入信号902和906中的每个序号从每个在前输入信号902和906的序号递增，序号将在相对短的时间周期内翻转。维持唯一的定时系统的一个方案是增加每个序号使用的位数。该方案具有的缺点是增加了输入信号902和906的长度。在代表性实施例中，序号是6位长。在可替换实施例中，序号为16位长。基准目标924接收输入信号902和906，并将它们转换为交叉基准信号928，该交叉基准信号928包括基准序号，该基准序号包括足够的位数，使得维持唯一的时间基准。在代表性实施例中，基准序号是64位长。交叉基准信号928在CCPU24内本地使用以驱动本地处理930以及在网络22上发送到节点电子单元20，在节点电子单元20中交叉基准信号928用作每个节点电子单元20定时处理的输入信号。
上述的配电多台同步冗余计算机方法和系统是节省成本的并且可靠性高。每个系统包括中央控制处理单元(CCPU)和网络设备，从而有助于保护一组开关装置。多台冗余计算机采用具有各种备份的外部硬件时钟进行同步，这些备份用于在设备故障和维护期间保持同步。每个断路器本地的设备监测来自传感器的电压和电流信号，该传感器位于每个断路器附近。CCPU从高速网络上的所有设备接收所有的监测信号。为了确保在一个节点电子单元上测得的参数与在另一个节点电子单元上测得的参数一致，配电系统内所有的CCPU和所有的节点电子单元与初始时钟进行同步。然后CCPU可基于全局电压和电流信号对每个断路器节点电子单元执行保护和优化算法。因此，配电系统硬件时钟有助于以节约成本和可靠的方式运行的电源系统的保护和优化。
配电系统元件的代表性实施例在上面进行了详细描述。但这些元件并不局限于在此描述的特定实施例，而是，每个系统的元件可单独并与在此描述的其他元件分开使用。每个配电系统元件也可与其他配电系统元件结合使用。
尽管本发明已经依据各种特定实施例进行描述，本领域的技术人员知道本发明可用落入权利要求的精神和范围内的改变来实施。
