Description
技术领域technical field
本发明涉及通信领域，具体而言，涉及一种供电方法及装置。The present invention relates to the communication field, in particular, to a power supply method and device.
背景技术Background technique
目前的移动终端中，增加充电宝功能已经比较常见，而且供电标准都需要支持BC1.2标准，一般有三种供电方式：第一种是以标准下行端口(Standard downstream port，简称为SDP)的方式向外部供电，第二种是不支持连环充电的专用充电端口(Dedicated charger port，简称为DCP)方式向外部供电，第三种是支持连环充电的DCP方式向外供电。In the current mobile terminals, it is common to add power bank functions, and the power supply standard needs to support the BC1.2 standard. Generally, there are three power supply methods: the first is the standard downstream port (SDP for short) method To supply power to the outside, the second is a dedicated charging port (Dedicated charger port, referred to as DCP) that does not support serial charging to supply power to the outside, and the third is the DCP that supports serial charging to supply power to the outside.
其中，第一种供电方式是将移动终端通过通用串行总线(Universal Serial Bus，简称为USB)的id管脚下拉，枚举为USB主设备，然后以SDP的方式给从设备供电，这种供电方式一般最高供电为5V/500mA，供电的电流较小，充电时间较长。Among them, the first power supply method is to pull down the id pin of the mobile terminal through the Universal Serial Bus (USB for short), enumerate it as a USB master device, and then supply power to the slave device in the form of SDP. The power supply mode generally has a maximum power supply of 5V/500mA, the power supply current is small, and the charging time is long.
第二种供电方式是将移动终端以DCP的方式向外供电，这种供电可以支持5V/1A、5V/2A等大电流充电，但是由于终端内部的一些因素，不支持连环充电，即给自己充电的同时不可以向外供电，这样会造成用户体验较差的问题。The second power supply method is to supply power to the mobile terminal in the form of DCP. This power supply can support high-current charging such as 5V/1A, 5V/2A, etc., but due to some internal factors in the terminal, it does not support serial charging. It is not possible to supply power to the outside while charging, which will cause poor user experience.
第三种供电方式既支持DCP供电又支持连环充电，但是连环充电的时候会存在用户误将USB的供电口连接到USB充电口的问题，这样不仅会消耗电池电量，增大系统功耗，而且会存在安全隐患。而针对该问题，目前尚未提出有效的解决方案。The third power supply method supports both DCP power supply and serial charging, but there will be a problem that the user mistakenly connects the USB power supply port to the USB charging port during serial charging, which will not only consume battery power and increase system power consumption, but also There will be safety hazards. For this problem, no effective solution has been proposed yet.

下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“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。It should be noted that the terms "first" and "second" in the description and claims of the present invention and the above drawings are used to distinguish similar objects, but not necessarily used to describe a specific sequence or sequence.
在本实施例中提供了一种供电方法，图1是根据本发明实施例的供电方法的流程图，如图1所示，该流程包括如下步骤：In this embodiment, a power supply method is provided. FIG. 1 is a flowchart of a power supply method according to an embodiment of the present invention. As shown in FIG. 1, the process includes the following steps:
步骤S102，判断对第一供电设备进行供电的设备是否是该第一供电设备；Step S102, judging whether the device that supplies power to the first power supply device is the first power supply device;
步骤S104，在判断结果为是的情况下，控制第一供电设备的充电输入功能关闭和/或控制第一供电设备的供电输出功能关闭。Step S104, if the judgment result is yes, control the charging input function of the first power supply device to be turned off and/or control the power supply output function of the first power supply device to be turned off.
其中，执行上述操作的可以是第一供电设备。在上述实施例中，控制充电输入功能关闭可以包括两种情况，一种是，当在执行S102的过程中，就已经执行了关闭充电输入功能的操作时，控制充电输入功能关闭是控制充电输入功能维持关闭状态；另一种是，在执行完S102之后，充电输入功能是开启的状态时，控制充电输入功能关闭是执行对充电输入功能的关闭操作，并在关闭充电输入功能之后，维持关闭状态。同样的，控制供电输出功能关闭也可以与上述描述类型的两种情况，一种是，当在执行S102的过程中，就已经执行了关闭供电输出功能的操作时，控制供电输出功能关闭是控制供电输出功能维持关闭状态；另一种是，在执行完S102之后，供电输出功能是开启的状态时，控制供电输出功能关闭是执行对供电输出功能的关闭操作，并在关闭供电输出功能之后，维持关闭状态。Wherein, it may be the first power supply device that performs the above operations. In the above-mentioned embodiment, controlling the charging input function to be turned off may include two situations. One is, when the operation of turning off the charging input function has been performed during the execution of S102, controlling the charging input function to be turned off is to control the charging input function. The function remains closed; the other is that after the execution of S102, when the charging input function is turned on, controlling the charging input function to turn off is to execute the closing operation of the charging input function, and after turning off the charging input function, keep it off state. Similarly, controlling the shutdown of the power supply output function can also be the same as the two situations described above. One is that when the operation of turning off the power supply output function has been performed during the execution of S102, the control of the shutdown of the power supply output function is the control The power supply output function remains in the closed state; the other is that after the execution of S102, when the power supply output function is in the open state, controlling the power supply output function to close is to perform a close operation on the power supply output function, and after closing the power supply output function, Stay closed.
由上述步骤可知，在检测出第一供电设备自充电时，会控制第一供电设备的充电输入功能关闭和/或控制第一供电设备的供电输出功能关闭，从而消除第一供电设备的自充电情况，避免了不必要的电量浪费，解决了相关技术中存在的消耗电池电量，增大系统功耗，存在安全隐患的问题，达到了避免不必要的电量消耗以及系统功耗，提高供电设备的安全性的效果。It can be seen from the above steps that when the self-charging of the first power supply device is detected, the charging input function of the first power supply device is controlled to be turned off and/or the power supply output function of the first power supply device is controlled to be turned off, thereby eliminating the self-charging of the first power supply device situation, avoiding unnecessary waste of power, solving the problems of battery power consumption, increasing system power consumption, and potential safety hazards in related technologies, and achieving avoidance of unnecessary power consumption and system power consumption, and improving the efficiency of power supply equipment safety effect.
在一个可选的实施例中，上述步骤S102中，判断对第一供电设备进行供电的设备是否是第一供电设备时，可以通过如下方式进行判断：在确定对第一供电设备进行供电的供电方式是专用充电端口DCP时，关闭所述第一供电设备的供电输出功能；在预定时间之后，检测第一供电设备是否仍能接收到电能(即，判断第一供电设备是否是自充电，如果能够接收到电能，说明第一供电设备不是自充电；如果不能够接收到电能，说明第一供电设备是自充电)；在检测结果为不能接收到电能的情况下，确定在关闭第一供电设备的供电输出功能之前为第一供电设备进行供电的设备是第一供电设备；和/或，在检测结果为仍能接收到电能的情况下，确定为第一供电设备进行供电的设备不是第一供电设备。其中，上述的预定时间需要根据具体情况进行设置。在本实施例中，通过判断外部供电设备的供电方式来确定第一供电设备是否有可能处于自充电的状态，并通过控制第一供电设备的供电输出功能还进一步进行确定，从而提高了确定第一供电设备是否是自充电的准确性。In an optional embodiment, in the above step S102, when judging whether the device that supplies power to the first power supply device is the first power supply device, the judgment can be made in the following manner: when determining the power supply that supplies power to the first power supply device When the method is a dedicated charging port DCP, turn off the power supply output function of the first power supply device; after a predetermined time, detect whether the first power supply device can still receive electric energy (that is, determine whether the first power supply device is self-charging, if If the power can be received, it means that the first power supply device is not self-charging; if the power cannot be received, it means that the first power supply device is self-charging); if the detection result is that the power cannot be received, it is determined that the first power supply device is turned off The device that supplied power to the first power supply device before the output function of the power supply is the first power supply device; and/or, in the case that the detection result is that it can still receive power, it is determined that the device that supplies power to the first power supply device is not the first power supply device power supply equipment. Wherein, the aforementioned predetermined time needs to be set according to specific situations. In this embodiment, it is determined whether the first power supply device may be in a self-charging state by judging the power supply mode of the external power supply device, and further determination is made by controlling the power supply output function of the first power supply device, thereby improving the determination of the second power supply device. An accuracy of whether the powered device is self-charging.

下面以充电宝为例对本发明进行详细说明：The present invention will be described in detail below by taking charging treasure as an example:
图7是根据本发明实施例的充电宝的结构框图，如图7所示，该充电宝包括微处理模块72(对应于上述的关闭模块24和开启模块64)、升压输出模块74、USB检测模块76(对应于上述的判断模块22和确定模块62)、充电控制模块78、电压检测模块710以及一个输出可控的LDO 712。下面对各模块进行说明：Fig. 7 is a structural block diagram of a charging treasure according to an embodiment of the present invention. As shown in Fig. The detection module 76 (corresponding to the judgment module 22 and the determination module 62 mentioned above), the charging control module 78 , the voltage detection module 710 and an LDO 712 with a controllable output. Each module is described below:
微处理模块72可以由一个单片机或者微处理器构成(例如，中央处理器(Central Processing Unit，简称为CPU)芯片)，主要进行软件指令的执行以及整个系统的控制。The micro-processing module 72 may be composed of a single-chip microcomputer or a microprocessor (for example, a central processing unit (Central Processing Unit, referred to as CPU) chip), and mainly executes software instructions and controls the entire system.
升压输出模块74以一个boost升压芯片实现，其内部可以由一个直流-直流(Direct Current-Direct Current，简称为DC-DC)升压电路实现，主要是对内部输出电压进行升压，使升压后的电压输出为标准值(例如，5V)。The boost output module 74 is implemented with a boost boost chip, and its interior can be realized by a DC-DC (Direct Current-Direct Current, referred to as DC-DC) boost circuit, mainly to boost the internal output voltage, so that The boosted voltage output is a standard value (for example, 5V).
USB检测模块76、充电控制模块78、电压检测模块710以及LDO712，这四个模块既可以以一个功能强大的充电芯片实现，也可以各自用单独芯片实现。The USB detection module 76, the charging control module 78, the voltage detection module 710 and the LDO712, these four modules can be implemented with a powerful charging chip, or can be implemented with a separate chip.
其中，上述的微处理模块72可以通过I2C总线(也可以使用其他的外设控制总线，如串行外设接口(Serial Peripheral Interface，简称为SPI)，通用异步接受器/发送器(Universal AsynchronousReceiver/Transmitter，简称为UART)等)控制升压输出模块74和充电控制模块78，并通过通用目的输入输出(General Purpose InputOutput，简称为GPIO)接收来自于充电控制模块78的中断信息。升压输出模块74通过对内部电压的升压处理，使USB输出管脚Vbus可以输出5V电压，其D+及D-(图7中的DP、DM分别指USB的D+、D-)管脚进行短接，使USB输出符合BC1.2中的DCP充电协议，模拟标准适配器。USB检测模块76通过检测输入端D+及D-电压变化，对插入的USB充电类型进行区分。输出可控的LDO 712，由充电控制芯片进行控制，进行使能和禁止操作。电压检测模块710用于检测外电是否正常，通过高低电平上报给充电控制模块78。充电控制模块78通过采集电压检测模块710及USB检测模块76，通过中断反映给微处理模块72，微处理模块72进行逻辑处理后通过I2C控制充电控制模块78对LDO 712进行使能控制。Wherein, the above-mentioned microprocessing module 72 can pass through the I2C bus (other peripheral hardware control buses can also be used, such as Serial Peripheral Interface (Serial Peripheral Interface, referred to as SPI), Universal Asynchronous Receiver/Transmitter (Universal Asynchronous Receiver/Transmitter) Transmitter (abbreviated as UART) etc.) control boost output module 74 and charging control module 78, and receive interrupt information from charging control module 78 through general purpose input and output (General Purpose Input Output, abbreviated as GPIO). The boost output module 74 makes the USB output pin Vbus output a 5V voltage by boosting the internal voltage, and its D+ and D- (DP and DM in FIG. 7 refer to D+ and D- of the USB respectively) pin Short circuit, so that the USB output complies with the DCP charging protocol in BC1.2, simulating a standard adapter. The USB detection module 76 distinguishes the USB charging type inserted by detecting the voltage change of the input terminals D+ and D−. The output controllable LDO 712 is controlled by the charging control chip to enable and disable operations. The voltage detection module 710 is used to detect whether the external power is normal, and report to the charging control module 78 through high and low levels. The charging control module 78 collects the voltage detection module 710 and the USB detection module 76, and reflects it to the microprocessing module 72 through an interrupt. The microprocessing module 72 performs logic processing and then controls the charging control module 78 to enable the LDO 712 through I2C.
其中，USB检测模块76的实现电路需要按照BC1.2协议实现，其检测流程包括：Wherein, the implementation circuit of the USB detection module 76 needs to be implemented according to the BC1.2 protocol, and its detection process includes:
1.Vbus检测。为确保针对连接至USB端口的任何设备进行正确排序，可以使连接器的Vbus和GND引脚比D+和D-引脚长。这样可确保长的引脚首先与插入设备保持接触。所以，发生任何检测之前，必须首先检测到Vbus，在本系统中，是由电压检测模块710进行Vbus检测的，电压检测模块710可以由一个电压比较器实现。1. Vbus detection. To ensure proper sequencing for any device connected to the USB port, the connector's Vbus and GND pins can be made longer than the D+ and D- pins. This ensures that the long pins stay in contact with the inserted device first. Therefore, before any detection occurs, the Vbus must be detected first. In this system, the Vbus detection is performed by the voltage detection module 710, which can be realized by a voltage comparator.
2.首次检测。该检测中，终端设备(例如，上述的充电宝)区分具有充电标签的500mA以上端口(CDP和DCP)与500mA以下端口(SDP)。终端设备需要在D+上使能0.5v至0.7v电压源，在D-上使能25μa至175μa流入电流源。如果连接的是DCP或CDP，在D-上将出现0.5v至0.7v电平；如果连接的是SDP，D-电压将下降至零。终端设备切入一个比较器，将D-电压与0.25v至0.4v进行比较。如果D-电压高于0.4v但低于逻辑低电平门限0.8v，终端设备则认为有充电端口出现。2. First detection. In this detection, the terminal device (for example, the above-mentioned power bank) distinguishes between ports with charging labels above 500mA (CDP and DCP) and ports below 500mA (SDP). End equipment needs to enable a 0.5v to 0.7v voltage source on D+ and a 25µa to 175µa sink current source on D-. If a DCP or CDP is connected, a 0.5v to 0.7v level will appear on D-; if an SDP is connected, the D- voltage will drop to zero. The end device switches into a comparator that compares the D- voltage to 0.25v to 0.4v. If the D- voltage is higher than 0.4v but lower than the logic low threshold of 0.8v, the end device considers that a charging port is present.
3.二次充电器检测。在该检测中，在关闭上述2中的电压源和电流源后，终端设备需要辨别CDP和DCP。按照反序执行上述测试，在D-作用0.5v至0.7v电压源，在D+作用50μa电流源。如果连接的是DCP，D+将出现0.5v至0.7v电平；如果连接的是CDP，D+电压为零。3. Secondary charger detection. In this detection, after turning off the voltage source and current source in the above 2, the terminal device needs to distinguish the CDP and DCP. Perform the above tests in reverse order, apply a 0.5v to 0.7v voltage source on D-, and apply a 50μa current source on D+. If a DCP is connected, D+ will have a level of 0.5v to 0.7v; if a CDP is connected, the D+ voltage will be zero.
以上检测逻辑都在USB检测模块76中以硬件电路实现，在检测时，可以由微处理模块73控制检测的开始，在D+、D-移除后，USB检测模块76以逻辑电平的变化的形式反映给充电控制模块78，最终充电控制模块78通过系统中断的方式上报给微处理模块72。The above detection logics are all implemented with hardware circuits in the USB detection module 76. During detection, the start of the detection can be controlled by the microprocessing module 73. The form is reflected to the charging control module 78, and finally the charging control module 78 reports to the microprocessing module 72 through a system interruption.
上述的USB输出端口是符合BC1.2标准的DCP端口。The aforementioned USB output port is a DCP port conforming to the BC1.2 standard.
上述的LDO 712可以是一个可以输出高阻态，并进行控制的LDO模块。The aforementioned LDO 712 may be an LDO module capable of outputting a high-impedance state and performing control.
图8是根据本发明实施例的充电宝设备检测到有充电设备插入时进行的检测流程图，如图8所示，该流程包括如下步骤：Fig. 8 is a flow chart of detection performed when the power bank device detects that a charging device is plugged in according to an embodiment of the present invention. As shown in Fig. 8, the process includes the following steps:
步骤S802，默认状态下，升压输出模块74及可控的LDO 712都是打开的，所以在有外电(即，外部的充电设备)插入的时候，微处理模块72首先会读取电压检测模块710的状态，电压检测模块710检测Vbus；Step S802, by default, both the boost output module 74 and the controllable LDO 712 are turned on, so when an external power (that is, an external charging device) is plugged in, the microprocessing module 72 will first read the voltage detection module The state of 710, the voltage detection module 710 detects Vbus;
步骤S804，通过检测Vbus判断外电是否存在，若存在转至步骤S806，否则，转至步骤S818；Step S804, judge whether the external power exists by detecting Vbus, if there is, go to step S806, otherwise, go to step S818;
步骤S806，电压检测模块710通过电压比较，确认外部供电是否正常，如果正常则控制USB检测模块76对D+、D-进行检测；Step S806, the voltage detection module 710 confirms whether the external power supply is normal through voltage comparison, and if it is normal, controls the USB detection module 76 to detect D+ and D-;

步骤S810，当确定充电方式是DCP时，将升压输出模块74关闭50ms，其中，该50ms为可控LDO 712以及电压检测模块710两个芯片的反应时间之和(当LDO 712和电压检测模块710的反应时间之和为其他值时，需要对上述关闭时间进行相应的调整)，具体可以从芯片手册中查询芯片的开关时间，上述关闭时间一般需要取开关时间最大值之和；Step S810, when it is determined that the charging mode is DCP, turn off the boost output module 74 for 50ms, wherein, the 50ms is the sum of the response times of the two chips of the controllable LDO 712 and the voltage detection module 710 (when the LDO 712 and the voltage detection module When the sum of the response time of the 710 is other values, the above closing time needs to be adjusted accordingly), and the switching time of the chip can be queried from the chip manual. The above closing time generally needs to be the sum of the maximum switching time;
步骤S812，读取电压检测模块710的状态，判断外电此时是否存在，若不存在，转至步骤S814，否则，转至步骤S816；Step S812, read the state of the voltage detection module 710, and judge whether the external power exists at this time, if not, go to step S814, otherwise, go to step S816;
步骤S814，关闭LDO 712，使其输出高阻；Step S814, closing the LDO 712 to make its output high impedance;
步骤S816，将升压输出模块74打开；Step S816, turn on the boost output module 74;
步骤S818，结束。Step S818, end.
正常状态下，系统没有检测到此时的状态时自充电状态，升压输出模块及可控LDO都是打开的，所以拔出时无论充电端或者被充电端都不进行任何处理，如果检测到上次的状态是自充电状态，此时用户将充电线拔出后，充电宝需要退出自充电状态，图9是根据本发明实施例的充电宝设备检测到有充电设备拔出时进行的检测流程图。如图9所示，该流程包括如下步骤：Under normal conditions, when the system does not detect the self-charging state at this time, the boost output module and the controllable LDO are both turned on, so no processing is performed on the charging end or the charged end when it is pulled out. The last state was the self-charging state. At this time, after the user pulls out the charging cable, the power bank needs to exit the self-charging state. Figure 9 is the detection performed when the power bank device detects that the charging device is pulled out according to the embodiment of the present invention. flow chart. As shown in Figure 9, the process includes the following steps:
步骤S902，充电宝退出自充电状态；Step S902, the power bank exits the self-charging state;
步骤S904，USB检测模块76检测到USB拔出事件后，会通过中断的方式通知微处理模块72此时有USB拔出事件；Step S904, after the USB detection module 76 detects the USB pull-out event, it will notify the microprocessing module 72 that there is a USB pull-out event by means of an interruption;
