Description

背景技术
随着世界范围内通信网络技术的普及和蓬勃发展，网络覆盖的广泛性和功能要求的全面性日益凸显；随之而来的，纳入系统综合管理的功能子单元、子设备也越来越多。对主设备而言，系统管理的第一步是判断和定位下属的子单元或子设备，然后再对下属的子单元或子设备进行相应的控制管理。判断和定位可通过硬件拨码方式实现：一位拨码可以设置高、低两位地址，通过在子单元或子设备对多位拨码的设置来确定其地址，同时用主设备的输入/输出端口来读取这个地址。一个端口信号可以读取一位拨码(即两个状态)的信号。

本公开的较佳实施方式
下面结合附图对本公开的实施方式进行描述。
值得说明的是，本文中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
第一实施例：
在本实施例中提供了一种子设备定位方法，图1是根据本公开第一实施例的子设备定位方法的流程图，如图1所示，该流程可包括如下步骤：
步骤S102，子设备接收主设备发送的检测信号；
与步骤S102对应，主设备可将检测信号发送给子设备，上述检测信号用于指示上述子设备根据上述检测信号处理得到子设备定位信息；接收上述子设备反馈的上述子设备定位信息。在上述主设备将检测信号发送给子设备之前，上述方法还可包括：主设备通过上述主设备中的检测判断模块将具有高低电平变化的信号转换为上述检测信号。上述具有高低电平变化的信号可包括主设备运行指示信号。上述检测判断模块可包括：主设备信号隔离电路、 检测信号驱动电路和检测信号输出隔离电路。
上述主设备信号隔离电路可包括：第一电阻，设置为：与上述具有高低电平变化的信号及第一三极管的基极相连；上述第一三极管设置为：上述第一三极管的基级通过第二电阻与第一电容与参考地相连，上述第一三极管的发射级与上述参考地相连，上述第一三极管的集电极与第二电阻相连，通过上述第二电阻输出隔离处理后的检测信号。上述检测信号驱动电路可包括：第一二极管，设置为：上述第一二极管的正端与上述主设备信号隔离电路输出的检测信号相连，同时通过第四电阻连接至电源；上述第一二极管的负端与第二三极管的基极相连，同时通过第五电阻连接参考地；上述第二三极管设置为：上述第二三极管的发射极连接上述参考地，上述第二三极管的集电极通过第六电阻连接至电源，同时上述第二三极管的集电极通过第七电阻和第一发光二极管连接至上述电源。上述检测信号输出隔离电路可包括：光耦，设置为：上述光耦的原边正输入端连接上述检测信号驱动电路驱动后的检测信号，上述光耦的原边输出端连接参考地；上述光耦的副边正输出端将检测信号通过第八电阻连接至对外电源，同时通过第二二极管的负端连接至上述光耦的副边负输出端；上述光耦的副边负输出端连接对外参考地。
步骤S104，对上述检测信号进行处理，得到子设备定位信息。
步骤S104可包括：将上述检测信号配置连接高电平，对应的上述子设备定位信息为高电平；或者将上述检测信号配置连接低电平，对应的上述子设备定位信息为低电平；或者将上述检测信号配置悬空，对应的上述子设备定位信息为高低电平。
步骤S106，将上述子设备定位信息反馈给主设备。
子设备将上述子设备定位信息反馈给主设备后，主设备可对子设备进行检测定位，对子设备进行相应的控制和操作；这样主设备可以实现利用一位端口信号检测出三种状态的功能，从而节约子设备与主设备的端口连线数并提高主设备中央处理器(Central Processing Unit，CPU)端口的利用率。
本公开实施例所使用的方法，子设备接收主设备发送的检测信号；对上述检测信号进行处理，得到子设备定位信息；将上述子设备定位信息反馈给主设备。本公开针对通讯系统综合管理的功能单元、子设备增多所导致的占 用主设备端口资源增多，主设备与子单元、子设备相连的连接器引脚数量增加、体积增大的情况，与通讯设备小型化、主设备端口有效利用率提高之间的矛盾；提供一种低成本的子单元、子设备定位检测的方法和系统。其在原来一位端口信号仅能够检测高、低两种状态的基础上，改进为利用一位端口信号检测出三种状态；不仅能够节约主设备与子单元、子设备间连接的引脚数量，从而缩小对应的连接器体积；还能够提高主设备端口资源利用率。同时，该方法实现方式简洁高效，涉及器件少；软件判断机制简单有效，大大降低了定位检测功能实现的复杂程度和成本，提高了可靠性；且使用方法简单，应用灵活性高。
第二实施例：
基于上述第一实施例的技术方案，以下结合第二实施例对上述技术方案进行详细说明。
在本实施例中提供了一种子设备定位方法，图2是根据本公开第二实施例的子设备定位方法的流程图，如图2所示，该流程可包括如下步骤：
首先，系统正常工作上电后，主设备中具有高低电平的运行指示信号RUN(一般为系统的运行指示灯信号)可接入检测判断模块。在检测判断模块中，经过处理，可得到同样具有高低电平的定位检测信号TEST(亦可简称为信号TEST)。同时，定位检测信号TEST与原RUN信号可以是隔离的，从而不会影响RUN信号的正常工作。
其次，运行指示信号RUN在检测判断模块中进行处理变化后成为定位检测信号TEST，并将TEST信号通过端口连线送入子单元或子设备中的信号定位上送模块中；
TEST信号可通过接口端子(占用一个引脚)接入子单元或子设备的信号定位上送模块中。在不同的子单元或子设备中，TEST信号在信号定位上送模块中处理方式可不同；可以上拉至高电平，可以下拉到参考地电平，还可以悬空；可以有三种处理方式。
第三，子设备中信号定位上送模块根据检测判断模块送入的定位检测信号TEST，处理为自身的定位检测信号，并将子设备自身的定位检测信号(即子设备自身的TEST信号)通过同一根端口连线送回主设备中的CPU；
被处理为上拉至高电平的TEST信号，尽管原RUN信号为高低电平，但其可被始终上拉为高电平信号(参见图2中子设备B)；同样的原理，被处理为下拉至参考地的TEST信号，也可始终呈现为低电平状态(参见图2中子设备A)；只有处理为悬空的TEST信号，仍然可保持高低电平信号的状态(参见图2中子设备C)。
第四，主设备中的CPU根据子设备送回的TEST信号进行定位判断后，对子单元或子设备进行后续的控制和操作；
这样，通过一个端口(占用1个引脚)，便可以检测出三种状态信息，从而获取三个子单元或子设备的定位信息；以此类推，通过两个端口(占用2个引脚)可检测六种状态信息，而一般应用只能检测四种状态信息；通过三个端口(占用3个引脚)可检测九种状态信息，而一般应用只能检测六种状态信息，等等。子单元、子设备越多，越能凸显出本公开的实用性；从而节约与主设备之间连接的引脚数量，缩小对应的连接器体积，大大提高了主设备端口资源利用率。同时，软件只需进行回读工作，对高电平(1)、低电平(0)和高低电平(10)进行判断，无需任何协议或解码编程工作，大大简化了软件的工作量。
本领域中的另外一种子设备定位方式可以是通过通讯方式实现：如通过RS485、控制器局域网络(Controller Area Network，CAN)、以太网等形式，来获取功能单元或子设备中存储的地址信息。这种方式的优势在于可获取多个单元或设备的地址信息；但前提是实现以下几点：1、在子单元或子设备中存在存储单元，并已提前烧写好地址信息；2、在子单元或子设备中存在通讯单元和处理单元电路，可实现对地址信息的读取和处理、上传。可见，该方式对子单元或子设备的硬件条件要求很高，而存储单元、通讯单元和处理单元电路往往成本很高且电路复杂；这使得许多本身不带有这些电路的子单元或子设备，在使用该方法时需增加这些电路单元，大大提高了硬件电路的复杂性和成本。同时，由于该方式需提前烧写好地址信息，一些紧急的现场需求、维护、整改环境往往不能够提供软件烧写条件，导致需要将这些子单元、子设备运输到可以烧写的环境中先进行处理；不仅延误时机，同时带来人力成本等的浪费，因此该方式在应用的灵活性上也存在很大制约。
通过本公开实施例提供的方案，在原来一位端口信号仅能够检测高、低两种状态的基础上，改进为利用一位端口信号检测出三种状态；不仅能够节约主设备与子单元、子设备之间连接的引脚数量，从而缩小对应的连接器体积；还能够提高主设备端口资源利用率。同时，该方案涉及器件少，软件判断机制简单有效，大大降低了定位检测功能实现的复杂程度和硬件、人力成本，提高了系统可靠性；从而为促进系统小型化和产品成本的降低，提高产品的市场竞争力做出贡献。
一可选实施例：
基于上述第一、第二实施例的技术方案，以下结合一可选实施例对上述技术方案进行详细说明。
在本实施例中提供了一种子设备定位方法中检测判断模块的电路图，如图3所示，检测判断模块可通过以三极管为核心器件的电路来实现；信号定位上送模块可以通过上拉至电源VDD、下拉至参考地GNDD以及悬空的方式实现。
检测判断模块还可以划分为但不限于RUN信号隔离电路(即主设备信号隔离电路)、TEST信号驱动电路(即检测信号驱动电路)以及TEST信号输出隔离电路(即检测信号输出隔离电路)三个子模块，如图3所示。
本实施例中的主设备信号隔离电路可为RUN信号隔离电路，包括：第一电阻R1，其一端与主设备运行信号RUN信号相连，另一端与第一三极管VT1的基极相连。第一VT1的基极同时还通过第二电阻R2和第一电容C1接入参考地GND。第一VT1的发射极连接到参考地GND。第一VT1的集电极可连接到第三电阻R3的一端；R3的另一端可输出隔离处理后的RUN-T信号。
三极管VT1可设置为：隔离RUN信号，防止后续对TEST信号进行处理时影响了RUN信号的正常工作；R1和R3分别作为基极、集电极的限流电阻，可设置为：调节和控制VT1基极、集电极的电流；R2是VT1发射极的反馈电阻；C1可设置为：对RUN信号进行滤波。
系统上电后，表示运行状态的RUN信号(通常为系统的运行指示灯信号)正常可为具有高低电平的信号；当其为高电平(1)时，三极管VT1可 导通，RUN-T信号被下拉为低电平；当RUN信号为低电平(0)时，三极管VT1可截止，RUN-T信号为高阻状态。
在使用本电路时可以注意的是，从可靠性角度出发，每个器件留够足够的余量；三极管VT1的Uceo需大于供电电压1.5倍以上，限流电阻R1、R3与VT1的基极、集电极电流也需相互配合。
本实施例中的检测信号驱动电路可为TEST信号驱动电路，包括：第一二极管VD1，第一二极管VD1的正端与RUN信号隔离电路输出的RUN-T信号相连，同时还通过第四电阻R4上拉至电源VCC。第一VD1的负端可与第二三极管VT2的基极相连，同时通过第五电阻R5接入参考地GND。第二VT2的发射极可接入GND。第二VT2的集电极可输出TEST-T信号，同时分别通过第六电阻R6和第七电阻R7、第一发光二极管HL1上拉至VCC。TEST-T信号可送入后级TEST信号输出隔离电路。
VD1可设置为：抬升VT2基极的导通电压，防止由于RUN-T信号受到干扰或RUN-T信号的低电平不够低时引起VT2误动作。VT2大致可设置为：进行信号驱动，保证TEST-T信号能输出有效的高电平信号(VCC)和低电平信号(GND)。HL1在这里可设置为：指示TEST-T信号的状态，方便调试时进行观察。
当前一级RUN信号隔离电路送来的RUN-T信号为低电平时，VT2可不导通，TEST-T信号被上拉电阻R6拉至高电平VCC(1)；当RUN-T信号为高阻状态时，VT2的基极可经R4、R5分压后得到一个较高的电压，导通VT2，TEST-T信号被下拉至低电平(0)。
总之，TEST-T信号可输出为一个隔离于RUN信号的高低电平信号。
可以注意的是，在使用本电路时预留够每个器件的余量；三极管VT2的Uceo需大于供电电压1.5倍以上，限流电阻R6等与VT2的集电极电流也需相互配合；VD1的导通压降不能取值太大，以导致RUN-T为高电平时也无法导通VT2的误动作发生。
TEST信号输出隔离电路可包括：
光耦D1，设置为：光耦D1的原边正输入端(1脚)接入TEST信号驱 动电路输出的TEST-T信号，光耦D1的原边输出端(2脚)接入参考地GND。光耦D1的副边正输出端(4脚)输出TEST信号，同时通过第八电阻R8上拉至对外电源VDD，并连接到第二二极管VD2的负端。光耦D1的副边负输出端(3脚)可接入对外参考地GNDD，同时可连接到第二二极管VD2的正端。
当子设备或子单元与主设备不是同一个电源、参考地时，光耦D1可以起到隔离作用，防止由于参考地不同导致的电路功能问题。如果子设备或子单板与主设备参考地、电源均相同，这里VDD可以接VCC，GNDD可以接GND。VD2可设置为：对输出到子设备或子单元上的TEST信号进行端口防护。子单板可以属于能源领域，子单板可以有多个；子设备也可以属于能源领域，子设备也可以有多个。
当TEST-T信号为高电平状态时，光耦D1的原边可导通，副边TEST信号被拉低至低电平GNDD(0)；当TEST-T信号为低电平状态时，光耦D1的原边可截止，副边TEST信号被R8上拉至高电平VDD(1)。总之，TEST信号也可以是一个具有高低电平的信号。该信号除送回至主设备CPU外，还可通过对外端口下送至子单元、子设备的信号定位上送模块。
可以注意的是，在使用本电路时预留够每个器件的余量；光耦D1副边的U CE要能够满足对外电源VDD并同时留有余量；VD2的参数也需和VDD相配合。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据实施例的方法可借助软件加所需的通用硬件平台的方式来实现，当然也可以通过硬件。基于这样的理解，本公开的技术方案本质上或者说对本领域做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本公开每个实施例的方法。
