After the control processor U1 is powered on, it first checks the voltage status of the first to third voltage detection ports GPIO1-3. Because the first interface J2 has power, the level of GPIO3 is high, and the control processor judges that an external power supply is plugged in. Configure the output of the first and second configuration ports GPIO4/5 and the first and second control ports GPIO8/9 as high level, so that the first MOS transistor switch Q1 of the first configuration unit and the second configuration unit of the second configuration unit The MOS tube switch Q4 is not conducting, and the voltage terminal VBUS of the state terminal ID1 and ID2 of the second interface and the third interface connected to the network is at a high level, so no matter which device J3 and J5 are inserted into, the second interface and the third interface are both Configured for charging state. At the same time, since the first and second control ports GPIO8/9 are at high level, the third MOS transistor switch Q2 and the fourth MOS transistor switch Q3 are turned on, thereby triggering the closing of the first and second relay switches J1 and J4, that is, the first The first switch circuit and the second switch circuit are turned on, so that the external power supply of the first interface J2 can charge the electronic equipment of the second interface J3 and the third interface J5. In addition, the control processor U1 controls the indicator port JPIO11 and JPIO12 to output a high level through a program, and lights up the first and second light-emitting diodes D4/D5 to indicate the direction of the charging current.
(2)当第一接口J2悬空(不连接任何适配器或电源)，第二接口J3连接蓝牙指纹仪、蓝牙耳机等不带OTG功能的设备，第三接口J5连接带OTG功能的手机、pad等设备。(2) When the first interface J2 is suspended (not connected to any adapter or power supply), the second interface J3 is connected to devices without OTG functions such as Bluetooth fingerprint readers and Bluetooth headsets, and the third interface J5 is connected to mobile phones and pads with OTG functions. equipment.
由于第一接口J2悬空其电压端VBUS0为低电平，此时控制处理器未上电工作，默认第一、第二配置端口GPIO4、GPIO5输出为低电平，此时第一、第二配置单元的MOS管开关Q1和Q4是导通的，所以第二接口J3和第三接口J5的状态端ID1和ID2接地，为低电平。而第三接口J5连接支持OTG功能的电子设备，其电压端VBUS2有电压为+5v，因此第三二极管D3导通给控制处理器U1供电，控制处理器U1上电工作，首先第一至第三电压检测端口GPIO1-3的电压状态，此时只有第一电压检测端口GPIO1为高电平，判断只有第三接口J5有电，而当前第二接口J3虽然没有电但状态端ID1已经被拉低，所以控制处理器控制第一控制端口GPIO8为低电平，Power1网络被拉低，第二控制端口GPIO9为高电平，Power2网络被拉高，因此第三MOS管开关Q2不导通，第一继电开关器J1不动作处于断开状态，即第一开关电路不导通，第四MOS管开关Q4导通，第二继电器开关J4闭合，即第二开关电路导通，J4的第1脚连接第四脚将第三接口J5的电压端VBUS2连接第二接口J3的电压端VBUS1，实现第三接口的电子设备给第二接口的电子设备充电。另外控制处理器U1通过程序控制指示灯端口JPIO11输出高电平，点亮第一发光二极管D4，指示充电电流方向。Since the first interface J2 is floating, its voltage terminal VBUS0 is at low level. At this time, the control processor is not powered on. By default, the output of the first and second configuration ports GPIO4 and GPIO5 are at low level. At this time, the first and second configuration ports The MOS transistor switches Q1 and Q4 of the unit are turned on, so the state terminals ID1 and ID2 of the second interface J3 and the third interface J5 are grounded and are at low level. The third interface J5 is connected to an electronic device that supports the OTG function, and its voltage terminal VBUS2 has a voltage of +5v, so the third diode D3 is turned on to supply power to the control processor U1, and the control processor U1 is powered on to work. To the voltage state of the third voltage detection port GPIO1-3, at this time only the first voltage detection port GPIO1 is at a high level, and it is judged that only the third interface J5 has power, and the current second interface J3 has no power but the state terminal ID1 has is pulled low, so the control processor controls the first control port GPIO8 to be low, the Power1 network is pulled low, the second control port GPIO9 is high, and the Power2 network is pulled high, so the third MOS tube switch Q2 does not conduct On, the first relay switch J1 does not act and is in the off state, that is, the first switch circuit is not conducting, the fourth MOS transistor switch Q4 is conducting, the second relay switch J4 is closed, that is, the second switching circuit is conducting, J4 The first pin is connected to the fourth pin to connect the voltage terminal VBUS2 of the third interface J5 to the voltage terminal VBUS1 of the second interface J3, so that the electronic equipment of the third interface can charge the electronic equipment of the second interface. In addition, the control processor U1 controls the indicator port JPIO11 to output a high level through a program, and lights up the first light-emitting diode D4 to indicate the direction of the charging current.
同理，若第一接口J2悬空，第三接口J5连接蓝牙指纹仪、蓝牙耳机等不带OTG功能的设备，第二接口J3连接带OTG功能的手机、pad等设备，该充电电路实现第二接口的电子设备给第三接口的电子设备充电，第二发光二极管D5点亮，指示充电电流方向。Similarly, if the first interface J2 is suspended, the third interface J5 is connected to devices without OTG function such as Bluetooth fingerprint reader and Bluetooth headset, and the second interface J3 is connected to devices such as mobile phones and pads with OTG function, the charging circuit realizes the second The electronic equipment on the interface charges the electronic equipment on the third interface, and the second light emitting diode D5 lights up to indicate the direction of the charging current.
(3)当第一接口J2悬空(不连接任何适配器或电源)，第二接口J3和第三接口J5均连接带OTG功能的手机、pad等设备。(3) When the first interface J2 is suspended (no adapter or power supply is connected), the second interface J3 and the third interface J5 are both connected to mobile phones, pads and other devices with OTG functions.
第一接口J2悬空，第二接口J3和第三接口J5的状态端ID1和ID2默认为低电平。由于第二接口J3和第三接口J5均为带OTG功能电子设备，其电压端VBUS1和VBUS2均有电，因此第二二极管D2和第三二极管D3导通，控制处理器U1上电工作。控制处理器U1检测第一至第三电压检测端口GPIO1-3的电压状态，判断第二接口J3和第三接口J5均支持OTG功能，但目前需要一个对另一个设备供电，控制处理器执行默认程序配置，配置第二配置端口GPIO5输出为高电平，将POWER_EN_2网络拉高，第二MOS管开关Q4不导通，将第三接口的状态端ID2连接到网络电压端，从而控制第三接口状态端ID2为高电平，第三接口J5配置为充电状态，因此第三接口J5连接的电子设备的OTG功能被关闭，只能用作被充电设备，而第二接口J3连接的电子设备用作放电设备。控制处理器控制第一控制端口GPIO8为低电平，Power1网络被拉低，第二控制端口GPIO9为高电平，Power2网络被拉高，因此第三MOS管开关Q2不导通，第一继电开关器J1不动作处于断开状态，即第一开关电路不导通，第四MOS管开关Q4导通，第二继电器开关J4闭合，即第二开关电路导通，J4的第1脚连接第四脚将第三接口J5的电压端J5连接第二接口J3的电压端，实现第二接口的电子设备给第三接口的电子设备充电。另外，控制处理器U1通过程序控制指示灯端口JPIO12输出高电平，点亮第二发光二极管D5，指示充电电流方向。The first interface J2 is floating, and the state terminals ID1 and ID2 of the second interface J3 and the third interface J5 are at low level by default. Since the second interface J3 and the third interface J5 are both electronic devices with OTG functions, and their voltage terminals VBUS1 and VBUS2 are powered, the second diode D2 and the third diode D3 are turned on, and the control processor U1 Electric work. The control processor U1 detects the voltage status of the first to third voltage detection ports GPIO1-3, and judges that both the second interface J3 and the third interface J5 support the OTG function, but currently one needs to supply power to the other device, and the control processor executes the default Program configuration, configure the output of the second configuration port GPIO5 to be high level, pull the POWER_EN_2 network high, the second MOS tube switch Q4 is not turned on, and connect the status terminal ID2 of the third interface to the network voltage terminal to control the third interface The state terminal ID2 is high level, and the third interface J5 is configured as a charging state, so the OTG function of the electronic device connected to the third interface J5 is turned off, and can only be used as a charged device, while the electronic device connected to the second interface J3 is used as a discharge device. The control processor controls the first control port GPIO8 to be low level, the Power1 network is pulled low, the second control port GPIO9 is high level, and the Power2 network is pulled high, so the third MOS tube switch Q2 is not turned on, and the first relay The electric switch J1 is in the off state without action, that is, the first switch circuit is not conducting, the fourth MOS tube switch Q4 is conducting, the second relay switch J4 is closed, that is, the second switching circuit is conducting, and the first pin of J4 is connected The fourth pin connects the voltage terminal J5 of the third interface J5 to the voltage terminal of the second interface J3, so that the electronic equipment of the second interface can charge the electronic equipment of the third interface. In addition, the control processor U1 controls the indicator port JPIO12 to output a high level through a program, and lights up the second light-emitting diode D5 to indicate the direction of the charging current.
若默认程序配置不符合使用者要求，使用者想通过第三接口J5的电子设备对第二接口J3的电子设备充电，可以通过切换开关K1来切换。程序默认切换信号输入端口GPIO10是高电平，当切换开关K1触发时，端口GPIO10被拉低为低电平，控制处理器U1检测到电平变化后判断开关K1被触发，控制处理器U1控制第二控制端口GPIO9输出为低电平，将POWER2网络拉低，从而第四MOS管开关不导通，第二继电器J4断开，先切断第第二接口向第三接口的充电。之后控制处理器U1配置第二配置端口GPIO5为低电平，将POWER_EN_2网络拉低，使得第三接口J5状态端ID2为低电平，配置为放电状态，第三接口J5的电子设备的OTG功能被打开，然后控制处理器U1配置第一配置端口GPIO4输出为高电平，将POWER_EN_1网络拉高，使得第二接口状态端ID1为高电平，配置为充电状态，第二接口J3的电子设备的OTG功能被关闭，实现第三接口的电子设备给第二接口的电子设备充电。另外，控制处理器U1通过程序控制指示灯端口JPIO11输出高电平，点亮第一发光二极管D4，指示充电电流方向。If the default program configuration does not meet the user's requirements, and the user wants to charge the electronic device on the second interface J3 through the electronic device on the third interface J5, the user can switch it by switching the switch K1. The program defaults to switch the signal input port GPIO10 to a high level. When the switch K1 is triggered, the port GPIO10 is pulled down to a low level. After the control processor U1 detects the level change, the judgment switch K1 is triggered, and the control processor U1 controls The output of the second control port GPIO9 is low level, which pulls down the POWER2 network, so that the fourth MOS transistor switch is not conducted, the second relay J4 is disconnected, and the charging from the second interface to the third interface is firstly cut off. Afterwards, the control processor U1 configures the second configuration port GPIO5 to be at a low level, and pulls the POWER_EN_2 network low, so that the state terminal ID2 of the third interface J5 is at a low level, configured as a discharge state, and the OTG function of the electronic device of the third interface J5 is turned on, and then the control processor U1 configures the output of the first configuration port GPIO4 to be high, and the POWER_EN_1 network is pulled high, so that the second interface state terminal ID1 is high, and it is configured as a charging state. The electronic device of the second interface J3 The OTG function of the device is turned off, so that the electronic device with the third interface can charge the electronic device with the second interface. In addition, the control processor U1 controls the indicator port JPIO11 to output a high level through a program, and lights up the first light-emitting diode D4 to indicate the direction of the charging current.
