Description

线缆和电子设备 技术领域
本公开属于线缆技术领域，具体涉及一种具有插拔检测功能的线缆，以及相应的电子设备。
背景技术
电子设备常常需要各种线缆来提供电源或传输数据。为了提供电源或传输数据，线缆需要稳固地连接于电子设备的相应的接口中。为了防止线缆与设备接口之间接触不良或被恶意断开，现有技术已提出了一些用于线缆与接口的插拔检测或紧密度检测的技术。
例如在公告号为CN209046357U的中国实用新型专利中就提出一种带接口监控装置的UPS设备，该UPS设备内设有接口监控装置，所述接口监控装置包括若干个微压力传感器、微处理器以及报警器，处理器分别与微压力传感器和报警器信号相连。接口监控装置在线缆插头插入未完全到位时，能够通过报警器进行报警，提示工作人员重新将线缆插头插入到位，以保证UPS设备的正常工作。
然而，现有技术的线缆插拔检测往往需要电子设备来进行，例如在上述CN209046357U提出的方案中，需要在该UPS设备内额外地设置一个接口监控装置，并执行相应的接口监控步骤。这使得线缆插拔检测技术需要对电子设备进行专门的设计或改进，而无法对所有电子设备通用，由此妨碍了线缆插拔检测技术的广泛应用。因此，当前极需一种能够对所有电子设备都能直接利用而无需进行专门设计或改进的线缆插拔检测技术。
发明内容
有鉴于此，本公开的主要目的是解决现有的线缆插拔检测技术通用性差，应用扩展性不强的问题。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
为了解决现有的线缆插拔检测技术通用性差，应用扩展性不强的问题，本公开另辟蹊径，不再寻求在电子设备或电子设备的接口上实现插拔检测，而是将插拔检测功能实现在线缆上。这样，则无需对电子设备进行重新设计或改进，只需要将现有的线缆更换成本实用新型的线缆即可实现插拔检测，由此大大地提高了技术的通用性和应用的广泛性。
应当说明的是，本公开中的称的线缆一般是指电子线缆，即线缆中至少包括一对能够传输电流或电子信号的导线。但是，本公开也不排除可以应用于某些传送光信号的光缆中，只要该光缆中能够包含用于传送电子信号的导线即可。此外，本公开中的称的线缆对于其连接的接口没有任何的限制，与之相连的接口可以是符合特定标准的现有接口类型，也可以是不按标准定义的专用接口。
具体来说，本公开的线缆至少包括两个接口，为了进行区分，在此称为第一接口和第二接口。当然，除了接口之外，线缆还应至少包括电性连通所述接口导线。导线可以用来传输电流，电流可用作能量的载体，也可用作信号的载体，本公开不限于所述导线中传输的电流的作用。
此外，现有的线缆具有一接二、一接多或多接多等不同的类型，此时，一条线缆可能包括不止两个接口。因此本公开中所称的第一接口和第二接口并非特指某一个接口，其也可能包括不止一个接口，第一接口和第二接口本质指的能量或信号流入与流出的不同而区分的不同接口。
本公开中，所述第一接口、第二接口分别用于连接主设备接口和从设备接口。这里所称的主设备接口和从设备接口分别对应主设备和从设备。需要说明的是，本公开中，主设备和从设备并非是设备本身功能上的主从之分，而是将接收插拔检测信号的设备称为主设备，不接收插拔检测信号的设备称为从设备，插拔检测信号的产生和传输将在下文中说明。
为了进行插拔检测，本公开的线缆还包括传感器，传感器位于所述第一接口和第二接口中的至少一个，用于检测第一接口和/或第二接口是否被插入设备接口并生成检测信号。本公开不限于具体的插拔检测的传感器类型，例如可以采用压电传感器、霍尔传感器、光电传感器、光敏电阻、微动传感器、距离传感器或基于MEMS的传感器等。本公开中优选为采用压电传感器并产生模拟的检测信号。
本公开的线缆还包括处理电路，处理电路包括模数转换元件，模数转换元件连接至所述传感器的输出端，用于对传感器的输出的模拟检测信号进行模数转换后生成数字检测信号，该数字检测信号由所述处理电路传输至所述主设备接口。
所述的主设备接口是位于主设备上的接口，相应的，所述的从设备接口是位于从设备上的接口。本公开对于主设备和从设备的功能没有限制，对于设备的操作系统、接口类型也没有限制。也就是说，本公开原则上可以应用于任何电子设备。特别地，本公开对于那些具有专用操作 系统，不便于安装软件，接口本身也较为复杂的工控机等工业控制主机更加适用。
本公开将传感器和处理电路都设置于线缆中，由于，无需在设备接口中设置传感器和处理电路，使得设备本身不需要进行专门的设计或改进就实现了插拔检测的功能。
作为可选的实施方式，当线缆较长或传感器本身的原因导致检测信号较较弱时，在所述处理电路中还可以包括放大器，以便对所述模数转换元件生成的数字信号进行放大。对信号进行放大之后，有利于将信号传输到更远的距离。
值得注意的是，本公开尽管选择将检测信号传输到主设备接口，但这并不意味着必须在主设备中处理该检测信号。当然，如果主设备中提供相应的处理程序或处理软件，对该检测信号进行处理后再进行进一步的动作，是本公开的一种优选的实施方式。但是，作为其他的优选实施方式，也可以由所述线缆本身来对所述检测信号进行反应或动作，从而使得本公开的具有插拔检测的线缆可以即插即用，不会造成主设备额外的负担。
作为一种优选实施方式，本公开的处理电路还包括指示灯，该指示灯可用于指示所述数字检测信号的状态。如前所述，模数转换器将模拟的检测信号转换为数字检测信号。该数字检测信号的状态表示的是传感器所检测到的插拔状态，由此，为了直接的显示插拔状态，使用指示灯来显示数字检测信号的状态，即可使用户清楚地知道当前线缆相应接口的插拔状态。例如，可以用LED灯的点亮来指示相应的线缆接口未插入或被拔出的状态。也可以用指示灯的颜色，例如红色的LED指示线缆接口未插入或被拔出的状态，绿色的LED灯指示线缆接口被插入的状态。同时，由于本公开在线缆的不同接口均可设置传感器，由此，所述指示灯的数量可以与传感器的数量对应，以此分别指示源自不同传感器的数字检测信号的状态。
作为一种优选实施方式，本公开的所述处理电路还包括声音报警器，例如蜂鸣器，并且，当所述数字检测信号的处于预定状态时，该声音报 警器进行声音报警。例如，当数字检测信号表示的插拔状态是未连接或被拔出时，则该蜂鸣器进行蜂鸣报警。
如前所述，检测信号被传送到主设备接口，主设备可以对该检测信号进行处理。作为一种实施方式，主设备包括示警装置，其用于接收并处理来自所述主设备接口的数字检测信号，以根据该数字检测信号的状态进行示警操作。所述的示警操作例如是声、光、电等报警，也可以是向特定中控设备发送特定信息，或者通过电话、短信等方式向特定人员的终端设备示警。
下面参照附图来进一步描述本公开的实施方式。
图1是现有技术的一种USB线缆的一个实施例的结构示意图。如图1所示，该USB线缆包括第一接口1和第二接口2，第一接口1和第二接口2由导线部分连接。相比于现有技术，图2示出了本公开的一种USB线缆的结构。与现有技术不同的时，该线缆的导线路分中还包括一个凸起的容腔部分3。
图3是图2所示的USB线缆的第一实施例的剖视图。如图3所示，在所述USB线缆的的第一接口1中具有多个第一端子101，在第二接口2中具有多个第二端子201，第一端子和第二端子202通过导线401连接。此外，在所述容腔部分3中设置有一个处理电路301，该处理电路可以由薄片形的电路板及其上的电路元件构成。所述导线401与该处理电路301的电路部分不相接触，即该处理电路301不影响所述导线401的信号传输。所述的处理电路301至少包括模数转换元件。
再参见图3，该实施例的第一接口1和第二接口2中还分别设置有传感器，其用于检测接口的插拔状态。在第一接口1中的为第一传感器102，在第二接口2中的为第二传感器202。所述第一传感器102和第二传感器202均通过检测线302与处理电路301连接。检测线用于将第一传感器102和第二传感器202输出的模拟检测信号传输至所述处理电路301的模数转换元件(图3中未示出)。模数转换元件用于对第一传感器102和第二传感器202的输出的模拟检测信号进行模数转换后生成数字检测信号，该数字检测信号由所述处理电路传输至所述主设备接口。所 述模数转换元件例如是模数转换器，其可以是一个或两个。当模数转换器是一个时，其具有多路输入和多路输出，以便分别将第一传感器102和第二传感器202的模拟检测信号转换为两路数字检测信号。当模数转换器是两个时，其分别接收第一传感器102和第二传感器202的模拟检测信号并分别输出数字检测信号。
在该实施例中，所输出的两路数字检测信号分别通过信号线(图3中未示出)传输至与第一接口1连接的电子设备中。但是，这只是一种可选的实施方式，并非所有的实施方式中，都需要将两路数字检测信号传输至与线缆连接的电子设备。
在该实施例中，线缆的处理电路301由主设备接口供电，因此，线缆还包括有电源线303，其连接所述处理电路301和所述主设备接口的供电端子103，以便得所述处理电路由所述主设备接口供电。如图3所示，该实施例中的供电端子103不同于第一端子101，即为独立的供电端子。但是，供电端子也可以由第一端子101中的部分具有供电作用的端子实现。例如，在图4所示的另一实施例中，电源线连接至USB线缆的第一端子101中的两个具有供电作用的端子。需要指出的是，虽然在图3和图4中没有特别的画出，但是本领域技术人员应当理解，所述的电源线303通常包括两根导线，因此通常需要连接至两个端子。此外，为了保证供电稳定或，在处理电路中可以设置电压稳定电路或电流稳定电路。并且，当所述处理电路需要特定的电压供电时，在处理电路中可以设置相应的电压变换元件或相关的电路。以上电路均为本领域中的常规电路，在此不再具体说明。
图5是本公开的第三实施例的USB线缆的剖视图。作为第一和第二实施例的变化实施方式，在所述处理电路中可以设置可充电电池，该可充电电池的充电端连接到所述电源线303。可充电电池通过电源线进行充电，同时为处理电路301供电。在处理电路301中可提供相应的充电和放电电路进行支持。由此，当USB线缆和第一接口1正常连接到主设备接口时，主设备接口可以为处理电路301中的可充电电池供电，当第 一接口1从主设备接口断开或异常拔出时，可充电电池可以持续为处理电路供电，以提供信号处理以及告警操作。
图6是本公开的第四实施例的USB线缆的剖视图。如图5所示，与前面的实施例不同的是，该实施例不包括电源线303，取而代之以在容腔部分3中电池304。在具体实施时，可以使用可拆卸且通用的钮扣电池。为了在容腔部分3安装电池304，需要在容腔部分3上设置有电池容纳腔及相应的盖板。电池容纳腔及相应的盖板均为电子设备的惯用结构，因此在此不在赘述。
以上的各实施例中，USB线缆还包括线套，所述信号线、检测线和电源线等均共同包覆于所述线套中，所述容腔部分位于所述第一接口和第二接口之间，所述线套还包覆所述容腔部分。
需要说明的是，上述实施例仅以USB线缆为例进行说明，也就是说，上述实施例的第一接口1和第二接口2是兼容于USB标准的接口类型。但是，本公开不限于上体的接口类型，事实上，任何传输电源或信号的线缆且具有插拔检测需求的线缆均可应用于本公开，例如串口线和网口线等。
类似地，应当理解，为了精简本公开并帮助理解各个公开方面中的一个或多个，在上面对本公开的示例性实施例的描述中，本公开的各个特征有时被一起分组到单个实施例、图、或者对其的描述中。然而，并不应将该公开的方法解释成反映如下意图：即所要求保护的本公开要求比在每个权利要求中所明确记载的特征更多的特征。因此，遵循具体实施方式的权利要求书由此明确地并入该具体实施方式，其中每个权利要求本身都作为本公开的单独实施例。
本领域那些技术人员可以理解，可以对实施例中的设备中的模块进行自适应性地改变并且把它们设置在与该实施例不同的一个或多个设备中。可以把实施例中的模块或单元或组件组合成一个模块或单元或组件，以及此外可以把它们分成多个子模块或子单元或子组件。除了这样的特征和/或过程或者单元中的至少一些是相互排斥之外，可以采用任何组合对本说明书(包括伴随的权利要求、摘要和附图)中公开的所有特 征以及如此公开的任何方法或者设备的所有过程或单元进行组合。除非另外明确陈述，本说明书(包括伴随的权利要求、摘要和附图)中公开的每个特征可以由提供相同、等同或相似目的替代特征来代替。
此外，本领域的技术人员能够理解，尽管在此所述的一些实施例包括其它实施例中所包括的某些特征而不是其它特征，但是不同实施例的特征的组合意味着处于本公开的范围之内并且形成不同的实施例。例如，在权利要求书中，所要求保护的实施例的任意之一都可以以任意的组合方式来使用。
以上所述的具体实施例，对本公开的目的、技术方案和有益效果进行了进一步详细说明，应理解的是，本公开不与任何特定计算机、虚拟装置或者电子设备固有相关，各种通用装置也可以实现本公开。以上所述仅为本公开的具体实施例而已，并不用于限制本公开，凡在本公开的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
