The wireless terminal can be a handheld device with wireless connectivity, or other processing device connected to a wireless modem. For example, the wireless terminal can be a mobile phone, a computer, a tablet, a personal digital assistant (PDA), a mobile internet device (MID), a wearable device, and an e-book reader. Wait. As another example, the wireless terminal can also be a portable, pocket, handheld, computer built-in or in-vehicle mobile device. For convenience of description, in the following description of the embodiments of the present invention, the above-mentioned devices will be described by taking a terminal device as an example. The charging device provided in the embodiment of the present invention may specifically be a charger, a charging base or a charging treasure of the terminal device, and is not limited herein.
参见图1，是本发明实施例提供的一充电装置系统架构的一示意图。本发明实施例提供的充电装置系统架构中可包括终端设备及其充电装置，终端设备与充电装置通过充电组件连接。如图1所示，本发明实施例提供的终端设备可为腕表，该腕表也可为可穿戴设备中的一种。充电装置为腕表的充电底座。充电装置的连接组件为凸起的金属块，腕表的连接组件为凹槽中设置的金属块。如图2，是本发明实施例提供的充电组件连接的示意图。终端设备的连接组件与充电装置的连接组件一一配对进行连接。例如，终端设备可包括两 个连接组件，例如连接组件21和连接组件22，充电装置也可包括两个连接组件，例如连接组件11和连接组件12。终端设备与充电装置连接时，连接组件11与连接组件21配对连接，连接组件12与连接组件22配对连接。其中，上述连接组件21和连接组件22可为终端设备的电源正极管脚和电源负极管脚。FIG. 1 is a schematic diagram of a system architecture of a charging device according to an embodiment of the present invention. The charging device system architecture provided by the embodiment of the present invention may include a terminal device and a charging device thereof, and the terminal device and the charging device are connected by a charging component. As shown in FIG. 1 , the terminal device provided by the embodiment of the present invention may be a wristwatch, and the wristwatch may also be one of the wearable devices. The charging device is the charging base of the watch. The connecting component of the charging device is a raised metal block, and the connecting component of the wristwatch is a metal block disposed in the groove. FIG. 2 is a schematic diagram of a charging component connection provided by an embodiment of the present invention. The connection components of the terminal device are connected to the connection components of the charging device one by one. For example, the terminal device can include two The connection assembly, such as the connection assembly 21 and the connection assembly 22, may also include two connection assemblies, such as the connection assembly 11 and the connection assembly 12. When the terminal device is connected to the charging device, the connection assembly 11 is mated to the connection assembly 21, and the connection assembly 12 is mated to the connection assembly 22. The connection component 21 and the connection component 22 may be a power positive pin and a power negative pin of the terminal device.
可选的，终端设备的连接组件或者充电装置的连接组件的个数也可大于2，具体可根据实际应用场景确定，在此不做限制。当终端设备的连接组件多于2个时，可将其中2个作为终端设备的充电电源的正负极管脚。终端设备的充电电源正负极(例如连接组件21和22)与充电装置输出电源的正负极管脚(例如连接组件11和12)连接之后，充电装置上电之后则可为终端设备充电。若连接组件11和连接组件21之间(或者连接组件12和连接组件22之间)有液体沾染，则终端设备的电源正负极之间将出现液体沾染等效电阻，进而影响了终端设备的电源正极的电压稳定性。因此，充电装置可通过对终端设备的充电通路中充电电源正极等充电节点上的信号稳定性(如电压稳定性)的检测来判断充电装置和终端设备的连接组件之间是否出现异常短路故障，例如液体沾染等效电阻带来的电压值异常等故障。此外，若液体沾染导致的故障未处理，则将导致连接组件被腐蚀而被损坏，进而影响了充电装置或者终端设备的寿命。Optionally, the number of the connection components of the terminal device or the connection component of the charging device may also be greater than 2, which may be determined according to the actual application scenario, and is not limited herein. When there are more than two connection components of the terminal device, two of them may be used as the positive and negative pins of the charging power source of the terminal device. After the positive and negative charging power sources of the terminal device (for example, the connection components 21 and 22) are connected to the positive and negative terminals of the charging device output power source (for example, the connection components 11 and 12), the terminal device can be charged after the charging device is powered on. If there is liquid contamination between the connecting component 11 and the connecting component 21 (or between the connecting component 12 and the connecting component 22), a liquid-impregnated equivalent resistance between the positive and negative terminals of the power supply of the terminal device may occur, thereby affecting the terminal device. The voltage stability of the positive pole of the power supply. Therefore, the charging device can determine whether an abnormal short circuit fault occurs between the connection components of the charging device and the terminal device by detecting the signal stability (such as voltage stability) on the charging node such as the positive pole of the charging power source in the charging path of the terminal device. For example, the liquid is contaminated with an equivalent voltage and the voltage value is abnormal. In addition, if the failure caused by liquid contamination is not treated, the connection assembly will be corroded and damaged, thereby affecting the life of the charging device or the terminal device.

One end of the detecting module is connected to the control module, and the detecting module is configured to send a signal to the control module when detecting that the terminal device to be charged is accessed.

The switching unit may include: a plurality of analog switches, a digital switch, and a switching element such as a relay. The relay may include an electromagnetic relay or the like, and is not limited herein. One end of the foregoing control module is connected to the fault processing module, and the control module is configured to receive the terminal device sent by the detecting module. When the indication signal is connected, the triggering switch unit turns on the connection between the power input end of the terminal device and the driving power source, and triggers the detecting module to perform the path signal detection on the charging path of the terminal device. The charging path may be a connection path between the terminal device and the driving power source, and the path signal may be a signal such as a voltage value at a power input end of the terminal device. The driving power source is connected to a power input end of the terminal device, and the driving power source is configured to provide a driving voltage to the terminal device to detect a liquid contamination condition at a charging interface of the terminal device before the terminal device accesses the input power source. The detecting module is configured to detect whether an abnormality occurs in a path signal of a charging interface (for example, a power input end, for example, a positive power source of the terminal device) of the terminal device according to a driving voltage that is supplied to the terminal device by the driving power source.
具体实现中，终端设备连接到充电装置时，终端设备的连接组件与充电装置的连接组件连接，触发检测模块向控制模块发送信号。具体的，上述终端设备的连接组件可为突出的金属片，或者突出的机械开关或者终端设备磁铁等，相对应的充电装置的连接组件也可为突出的金属片，或者突出的机械开关，或者霍尔传感器等，在此不做限制。具体实现中，终端设备与充电装置连接之后，也可通过无线方式触发检测模块向控制模块发送信号。In a specific implementation, when the terminal device is connected to the charging device, the connection component of the terminal device is connected to the connection component of the charging device, and the trigger detection module sends a signal to the control module. Specifically, the connection component of the terminal device may be a protruding metal piece, or a protruding mechanical switch or a terminal device magnet, etc., and the connection component of the corresponding charging device may also be a protruding metal piece, or a protruding mechanical switch, or Hall sensors, etc., are not limited here. In a specific implementation, after the terminal device is connected to the charging device, the detection module can also be triggered to send a signal to the control module by using a wireless manner.
控制模块触发开关单元将充电装置的驱动电源输入通路导通到检测模块，检测模块可对充电通路的通路信号进行检测。若终端设备在电源正负极输入端(如图3中的电源输入端和接地端)之间有液体沾染，则终端设备侧将存在液体沾染所导致的等效电阻。液体沾染的等效电阻与终端设备内置的等效电阻形成并联状态，进而使得驱动电源提供的电压在终端设备的电源输入端出现偏置电压。驱动源的偏置电压指示着因为液体沾染而存在的等效电阻引起了终端设备的电源输入端的信号检测值偏离预设的信号阈值。检测模块只要检测到终端设备的电源接入端的信号检测值和预设的信号阈值不相同或者两者的差值超过预设差值范围，则可返回通路信号出现异常的信号给控制模块。其中，上述信号阈值具体可为电压阈值。具体实现中，终端设备与充电设备建立充电通路的连接之后，检测模块可检测终端设备的电源接入端的电压值(或称终端设备的充电接口的正负极之间的电压值)。若检测到的电压值与电压阈值相同，或者检测到的电压值与电压阈值的差值在预设差值范围内，则可确定充电通路处于正常工作状态。若检测到的电压值与电压阈值不相同，或者检测到的电压值与电压阈值的差值超过预设差值范围，则可确定充电通路出现了异常故障。The control module triggers the switch unit to conduct the driving power input path of the charging device to the detecting module, and the detecting module can detect the path signal of the charging path. If the terminal device has liquid contamination between the positive and negative input terminals of the power supply (such as the power input terminal and the ground terminal in Figure 3), there will be equivalent resistance caused by liquid contamination on the terminal device side. The equivalent resistance of the liquid contamination is in parallel with the equivalent resistance built into the terminal device, so that the voltage supplied by the driving power source has a bias voltage at the power input end of the terminal device. The bias voltage of the drive source indicates that the equivalent resistance present due to liquid contamination causes the signal detection value at the power input of the terminal device to deviate from the preset signal threshold. The detecting module may return a signal that the path signal is abnormal to the control module as long as it detects that the signal detection value of the power access end of the terminal device is different from the preset signal threshold or the difference between the two exceeds the preset difference range. The signal threshold may be a voltage threshold. In a specific implementation, after the terminal device establishes a connection with the charging device, the detecting module can detect the voltage value of the power receiving end of the terminal device (or the voltage value between the positive and negative terminals of the charging interface of the terminal device). If the detected voltage value is the same as the voltage threshold, or the difference between the detected voltage value and the voltage threshold is within a preset difference range, it may be determined that the charging path is in a normal working state. If the detected voltage value is not the same as the voltage threshold, or the difference between the detected voltage value and the voltage threshold exceeds the preset difference range, it may be determined that an abnormal fault has occurred in the charging path.
具体实现中，控制模块可在检测模块检测到通路信号异常时向故障处理模块发送触发信号以触发故障处理模块对通路信号异常的短路故障进行处理。In a specific implementation, the control module may send a trigger signal to the fault processing module when the detecting module detects that the path signal is abnormal, and trigger the fault processing module to process the short circuit fault of the abnormal path signal.
可选的，上述故障处理模块可为加热模块，例如发热电阻或者发热线圈等。可选的，上述加热模块可设置在充电装置的检测模块与终端设备的连接组件表面。例如，上述加热模块可为设置在图2所示的连接组件11和/或12的表面上的发热电阻或者发热线圈。发热电阻或者发热线圈可在接收到控制模块发送的触发信号时，加热连接组件11和/或12的表面，以蒸发连接组件11和/或12表面上的液体，解决液体沾染所导致的短路故障。Optionally, the fault processing module may be a heating module, such as a heating resistor or a heating coil. Optionally, the heating module may be disposed on a surface of the connection component of the detecting module and the terminal device of the charging device. For example, the above heating module may be a heat generating resistor or a heat generating coil provided on the surface of the connecting member 11 and/or 12 shown in FIG. 2. The heating resistor or the heating coil can heat the surface of the connecting component 11 and/or 12 when receiving the trigger signal sent by the control module to evaporate the liquid on the surface of the connecting component 11 and/or 12 to solve the short circuit fault caused by the liquid contamination. .
可选的，上述故障处理模块还可以为人机交互模块(或称警报模块)，例如，蜂鸣器、指示灯以及终端屏幕等。可选的，上述警报模块可在接收到控制模块发送的触发信号时，发出警报信号以提示终端设备的充电通路出现故障。其中，上述警报信号可为灯光、蜂鸣声、喇叭声或者文本信息等。例如，警报模块可通过蜂鸣器发声、指示灯闪烁、屏幕提示等方式提示终端设备用户清洁充电装置或者终端设备的充电接口。Optionally, the fault processing module may also be a human-computer interaction module (or an alarm module), for example, a buzzer, an indicator light, a terminal screen, and the like. Optionally, the foregoing alarm module may send an alarm signal to prompt the charging path of the terminal device to fail when receiving the trigger signal sent by the control module. The above alarm signal may be a light, a buzzer, a horn sound or a text message. For example, the alarm module may prompt the terminal device user to clean the charging interface of the charging device or the terminal device by buzzer sounding, blinking light, screen prompting, and the like.
进一步的，检测模块可周期性开启充电通路的通路信号检测，以确认通路信号的异常 故障是否消失。如果检测模块检测到终端设备的充电接口的正负极间的电压值为正常状态下的电压值(即预置电压阈值)，则返回正常信号给控制模块，控制模块将电源通路切换到电源输入端，即控制模块可触发开关单元导通终端设备的电源接入端与充电器(即输入电源)的充电通路，终端设备可进行正常充电。Further, the detecting module can periodically turn on the path signal detection of the charging path to confirm the abnormality of the path signal. Whether the fault has disappeared. If the detecting module detects that the voltage value between the positive and negative terminals of the charging interface of the terminal device is a voltage value in a normal state (ie, a preset voltage threshold), returning a normal signal to the control module, and the control module switches the power path to the power input. The control module can trigger the switch unit to turn on the charging access path of the power supply terminal of the terminal device and the charger (ie, the input power source), and the terminal device can perform normal charging.
进一步的，参见图4，是本发明实施例提供的短路故障处理电路的另一结构示意图。在一些可行的实施方式中，检测模块中可包括短路电压检测管脚，上述短路电压检测管脚与终端设备的电源输入端连接。上述检测模块用于在检测到待充电终端设备接入时，检测短路电压检测管脚的电压，并根据预设的电压阈值确定短路电压检测管脚的电压是否发出现异常。具体的，检测模块可周期性地检测短路电压检测管脚上的电压值，并可记录每个周期检测到的电压值。若某个检测周期检测到上述短路电压检测管脚的电压值与预设电压阈值不相同或者与预置电压阈值值的差值超过预设差值阈值，则可确定终端设备的充电通路的通路信号异常，进而可向控制模块发送信号。Further, referring to FIG. 4, it is another schematic structural diagram of a short circuit fault processing circuit according to an embodiment of the present invention. In some possible implementations, the detection module may include a short circuit voltage detecting pin, and the short circuit voltage detecting pin is connected to the power input end of the terminal device. The detecting module is configured to detect a voltage of the short-circuit voltage detecting pin when detecting the terminal device to be charged, and determine whether the voltage of the short-circuit voltage detecting pin is abnormal according to the preset voltage threshold. Specifically, the detecting module can periodically detect the voltage value on the short-circuit voltage detecting pin, and can record the voltage value detected in each cycle. If a detection period detects that the voltage value of the short-circuit voltage detecting pin is different from the preset voltage threshold or the difference between the preset voltage threshold exceeds the preset difference threshold, the path of the charging path of the terminal device may be determined. The signal is abnormal and can send a signal to the control module.
在本发明实施例中，充电装置的短路故障处理电路可通过检测模块检测终端设备的充电通路中的通路信号是否出现异常。若通路信号异常，则可通过控制模块触发故障处理模块对故障进行处理。故障处理模块可通过加热液体蒸发的方式解决故障，也可通过警报信号提示终端设备用户对故障进行处理，进而可保证终端设备的正常充电，提高终端设备和充电装置的使用寿命。In the embodiment of the present invention, the short circuit fault processing circuit of the charging device can detect whether an abnormality occurs in the path signal in the charging path of the terminal device through the detecting module. If the path signal is abnormal, the fault processing module can be triggered by the control module to process the fault. The fault processing module can solve the fault by heating the liquid evaporation, and can also prompt the terminal equipment user to handle the fault through the alarm signal, thereby ensuring the normal charging of the terminal equipment and improving the service life of the terminal equipment and the charging device.
下面将结合图5所述的电路结构，对本发明实施例提供的短路故障处理电路的实现方式进行描述。图5是本发明实施例提供的充电系统电路的一示意图。图5所示的充电系统架构中包括充电装置的充电模块以及终端设备本体的充电模块。其中，充电装置中的充电模块包括：输入电源VCC，电平转换单元，控制模块，检测模块，驱动电源VCC1以及故障处理模块。其中，控制模块包括控制单元和开关单元K1-1、和K1-2。加热模块可包括加热电阻RL和导通开关K2，控制单元可通过K2触发加热模块进行发热，进而可对充电通路的异常故障进行处理。检测模块包括检测模块1和检测模块2，其中，控制模块通过K1-2控制检测模块1与驱动电源的通路的导通或者短路。驱动电源VCC1通过一个二极管和分压电阻R1连接K1-2。检测模块2通过检测分压电阻R1端的电压值，确定终端设备的充电接口的正负极之间是否由异常电阻接入，例如液体沾染的等效电阻R3的接入与否。The implementation of the short circuit fault processing circuit provided by the embodiment of the present invention will be described below with reference to the circuit structure described in FIG. FIG. 5 is a schematic diagram of a charging system circuit according to an embodiment of the present invention. The charging system architecture shown in FIG. 5 includes a charging module of the charging device and a charging module of the terminal device body. The charging module in the charging device includes: an input power source VCC, a level converting unit, a control module, a detecting module, a driving power source VCC1, and a fault processing module. The control module includes a control unit and switch units K1-1, and K1-2. The heating module may include a heating resistor RL and a conduction switch K2, and the control unit may generate heat through the K2 trigger heating module, thereby processing an abnormal fault of the charging path. The detection module includes a detection module 1 and a detection module 2, wherein the control module controls the conduction or short circuit of the path of the detection module 1 and the driving power source through K1-2. The driving power supply VCC1 is connected to K1-2 through a diode and a voltage dividing resistor R1. The detecting module 2 determines whether the positive and negative terminals of the charging interface of the terminal device are connected by an abnormal resistance by detecting the voltage value of the voltage dividing resistor R1, for example, the access of the liquid-contaminated equivalent resistor R3.
终端设备本体中可包括充电模块和其他功能模块(图5中未示出)。其中，终端设备本体中的电阻可包括充电模块的内置电阻R4和等效初始电阻R2(例如终端设备的其他模块的等效电阻，如图3或图4中的终端设备等效初始电阻)。A charging module and other functional modules (not shown in FIG. 5) may be included in the terminal device body. The resistor in the terminal device body may include a built-in resistor R4 of the charging module and an equivalent initial resistor R2 (for example, an equivalent resistance of other modules of the terminal device, such as the equivalent initial resistance of the terminal device in FIG. 3 or FIG. 4).
具体实现中，终端设备充电底座可通过IO5检测RI与终端设备本体的接地端(GND，如终端设备的电源负极管脚)上的通流情况，以判断终端设备本体与充电底座是否建立连接。若IO5检测到终端设备本体与充电底座建立连接，则在终端设备的底座插上充电器(输入电源VCC接入)后，K1-1默认切断，K1-2默认打开，K2断开。检测模块2的输入/输出(input/output，IO)(如IO3)轮询与终终端设备本体的电源输入端的连接管脚的电压。终端设备本体与底座连接时，IO3管脚的电压的默认状态从VCC1被终端设备本体所包括的电阻拉低。其中，终端设备本体的R2和R4并联(可记为R2//R4)，并与R1串联至驱动电源VCC1，R1与R2//R4为驱动电压VCC1的分压电阻。根据VCC1，以及R1、R2和 R4可确定R1上或者R2//R4上分得的电压值，进而可预先设定正常工作状态下，终端设备的电源输入端C处的预置电压阈值。检测模块2如果检测到IO3口电压等于电源输入端C处(如电源正极管脚)的预置电压阈值，则可判定终端设备本体与底座的连接正常。检测模块2可向控制模块发送信号，控制模块可关闭K1-2，打开K1-1进入终端设备的正常充电流程。若检测模块2的IO3检测到的电压不在R1和R2//R4形成的分压范围内，而是落在了R1和R2//R3//R4形成的分压范围内，则可认为此时终端设备本体的电源接入端对地形成了异常短路/阻抗连接。检测模块2可向控制模块发送信号，控制模块可通过导通RL，使得RL发热迅速升温以使液体蒸发。其中，RL的发热温度小于电池的保护温度(例如58℃)。RL发热使得液体蒸发之后，R3消失，进而使得IO3出的电压落在R1和R2//R4形成的分压范围内(小于或者等于上述终端设备的电源输入端C的预置电压阈值)，使得终端设备的充电通路恢复正常。如果IO3检测到的电压恢复到R1和R2//R4的分压范围，则关闭K1-2，打开K1-1，进入到正常充电流程。在终端设备进入正常充电状态之前，IO2可持续检测K1-2的导通状态。终端设备进入到充电流程后，IO3通路切断。In a specific implementation, the terminal device charging base can detect the current condition of the RI and the ground end of the terminal device body (GND, such as the power source negative pin of the terminal device) through the IO5, to determine whether the terminal device body and the charging base establish a connection. If IO5 detects that the terminal device body is connected to the charging base, after the charger (input power supply VCC access) is inserted into the base of the terminal device, K1-1 is cut off by default, K1-2 is turned on by default, and K2 is disconnected. The input/output (IO) of the detection module 2 (such as IO3) polls the voltage of the connection pin with the power input terminal of the terminal device body. When the terminal device body is connected to the base, the default state of the voltage of the IO3 pin is pulled from VCC1 by the resistance included in the terminal device body. Wherein, R2 and R4 of the terminal device body are connected in parallel (which can be recorded as R2//R4), and are connected in series with R1 to the driving power source VCC1, and R1 and R2//R4 are voltage dividing resistors of the driving voltage VCC1. According to VCC1, and R1, R2 and R4 can determine the voltage value on R1 or R2//R4, and can preset the preset voltage threshold at the power input C of the terminal device under normal working conditions. If the detection module 2 detects that the voltage of the IO3 port is equal to the preset voltage threshold of the power input terminal C (such as the positive pole of the power supply), it can be determined that the connection between the terminal device body and the base is normal. The detecting module 2 can send a signal to the control module, and the control module can turn off K1-2 and open K1-1 to enter the normal charging process of the terminal device. If the voltage detected by IO3 of the detection module 2 is not within the partial pressure range formed by R1 and R2//R4, but falls within the partial pressure range formed by R1 and R2//R3//R4, it can be considered as this time. The power supply terminal of the terminal device body forms an abnormal short circuit/impedance connection to the ground. The detection module 2 can send a signal to the control module, and the control module can cause the RL to heat up rapidly to evaporate the liquid by turning on the RL. Wherein, the heating temperature of the RL is less than the protection temperature of the battery (for example, 58 ° C). After the RL heat causes the liquid to evaporate, R3 disappears, so that the voltage of IO3 falls within the partial pressure range formed by R1 and R2//R4 (less than or equal to the preset voltage threshold of the power supply input terminal C of the above terminal device), The charging path of the terminal device returns to normal. If the voltage detected by IO3 returns to the voltage division range of R1 and R2//R4, then K1-2 is turned off, K1-1 is turned on, and the normal charging process is entered. The IO2 can continuously detect the conduction state of K1-2 before the terminal device enters the normal charging state. After the terminal device enters the charging process, the IO3 path is cut off.
图5所示的系统结构中，终端设备充电底座可通过IO5检测RI与终端设备本体的接地端通路上的通流情况。当终端设备本体充电结束，终端设备用户断开终端设备本体与底座的连接时，IO5可检测到RI上的电流小于预设电流阈值，则可确定终端设备本体已断开连接，进而触发检测模块2的IO3轮询管脚电压的检测状态。In the system structure shown in FIG. 5, the terminal device charging base can detect the flow condition of the RI and the ground end path of the terminal device body through the IO5. When the terminal device body is charged and the terminal device user disconnects the terminal device body from the base, the IO5 can detect that the current on the RI is less than the preset current threshold, and then determine that the terminal device body has been disconnected, thereby triggering the detection module. 2 IO3 polls the detection status of the pin voltage.
可选的，上述检测模块1和检测模块2也可为同一个模块，具体可根据实际应用场景的电路设计需求确定，在此不做限制。Optionally, the foregoing detection module 1 and the detection module 2 may also be the same module, which may be determined according to the circuit design requirements of the actual application scenario, and is not limited herein.
