The method can be applied to terminal equipment such as smart phones, and for convenience in description, the terminal equipment in the embodiment of the application is provided with a first interface and a second interface by default. As shown in fig. 1, the method may include:

In the embodiment of the application, after the terminal equipment detects the inserting signal or the extracting signal of the equipment interface, the state of the first interface and the state of the second interface are determined, and the 4 paths are set to be in a connection state or a disconnection state according to the interface state, so that the charger or the external equipment inserted into the equipment interface can normally operate.
Fig. 2 is a schematic structural diagram of an equipment interface control system according to an embodiment of the present application. As shown in fig. 2, the system may include a battery 210, a charge controller 220, a first interface 230, and a second interface 240. The specific scene of the embodiment of the application is further described through the system.
The first scene is changed from suspension-suspension into other states:
if the second interface 240 remains suspended and the first interface 230 is changed from suspended to a plug-in charger, the charging controller 220 sets the first charging path to be in a connected state after detecting a charger insertion event, and the charger can charge the battery 210 through the first interface 230.
If the second interface 240 remains floating, the first interface 230 is changed from the plug-in charger to floating, and the charging controller 220 sets the first charging path to be in an off state after detecting the charger unplugging event.
If the second interface 240 remains suspended, the first interface 230 is changed from suspended to connected to the external device, and after the charging controller 220 detects the external device connection event, the first power supply path is set to be in a connected state, and the battery 210 can supply power to the external device through the first interface 230.
If the second interface 240 remains suspended, the first interface 230 is changed from plugging the external device to suspended, and after the charging controller 220 detects an external device unplugging event, the first power supply path is set to be in an off state, and the battery 210 stops supplying power outwards;
if the first interface 230 remains suspended and the second interface 240 changes from suspended to a plug-in charger, the charging controller 220 sets the second charging path to be in a connected state after detecting a charger insertion event, and the charger can charge the battery 210 through the second interface 240. In an actual scenario, the first interface 230 is usually an USB Type-C interface, the second interface 240 is a pogo pin interface, and unlike the first interface 230, the second interface 240 inserts a charger as a new event, and needs to reconfigure the related identifier and monitor of the event.
If the first interface 230 remains floating and the second interface 240 changes from being plugged into a charger to being floating, the charging controller 220 sets the second charging path to be in an off state after detecting a charger unplug event. The second interface 240 extracts the charger as a new event, and also needs to process the extracted event separately by newly adding interception, and delete the relevant identifier.
If the first interface 230 remains suspended and the second interface 240 changes from suspended to plug-in with an external device, the charging controller 220 sets the second power supply path to be in a connected state after detecting an external device insertion event, and the battery 210 can supply power to the external device through the second interface 240. And newly adding monitoring of the event, independently processing the external equipment unplugging event, and adding related identifiers. In an actual circuit, the power supply path and the charging path would communicate at the device interface, and the charging controller 220 would also set the second charging path to an off state in order to prevent current from flowing backward. In addition, the charging controller 220 also sets a current limit for the second power supply path, so that the power supply current meets the standard of the external device.
If the first interface 230 remains suspended and the second interface 240 changes from plugging the external device to suspended, the charging controller 220 sets the second power supply path to be in an off state after detecting the external device unplugging event, and the battery 210 stops supplying power. The unplugged event of the second interface 240 is a new event, and the associated identifier is cleared.
The second type of scene is changed from plug-in charger-suspension to other states:
if the first interface 230 remains a plug-in charger, the second interface 240 changes from floating to plug-in charger, and after detecting this event, the charging controller 220 sets the first charging path to an off state and the second charging path to an on state. Because the charger types of the first interface 230 and the second interface 240 are different, the charging parameters are also typically reconfigured. For example, if the charger inserted in the first interface 230 is a fast charger and the charger inserted in the second interface 240 is a normal charger, the normal charging parameters are configured after switching, and the fast charging identifier (three lightning) of the front end interface is switched to the normal charging identifier (single lightning). In the above process, the charger of the first interface 230 is equivalent to unplug, and in consideration of user experience, only the plug-in event may be reported in the software layer, the unplug event is not reported, and the unplug event is not displayed in the front end interface.
If the first interface 230 keeps the plug-in charger, the second interface 240 is changed from the plug-in charger to be suspended, after the charging controller 220 detects the event, the second charging path is set to be in an off state, and meanwhile, the first interface 230 is detected to be plugged into the charger, the charging stop flow is not entered, the first charging path is set to be in a connected state, and the charger charges the battery 210 through the first interface 230. Meanwhile, the charging parameters are reconfigured, and the common charging identification is switched into the quick charging identification.
If the first interface 230 is kept plugged with the charger, the second interface 240 is changed from suspended to plugged with the external device, and the charging controller 220 sets the second charging path to be in a connected state after detecting the event. The charger charges the battery 210 through the first interface 230, and the battery 210 supplies power to the external device through the second interface 240. In an actual scenario, the terminal device is charged through the first interface 230, and performs data interaction through the second interface 240, so as to realize cooperative work of the two device interfaces.
If the first interface 230 keeps the plug-in charger, the second interface 240 is changed from the plug-in external device to be suspended, and the charging controller 220 sets the second power supply path to be in an off state after detecting the event.
The third type of scene is changed from plugging external equipment-suspending into other states:
if the first interface 230 is kept plugged with an external device, the second interface 240 is changed from suspended to plugged with a charger, and after the charging controller 220 detects the event, the first power supply path is set to be in an off state and the second charging path is set to be in an on state. The charger plugged into the second interface 240 is usually low in power, and cannot supply power to the external device plugged into the first interface at the same time, so that the first power supply path needs to be cut off.
If the first interface 230 is kept plugged into an external device, the second interface 240 is suspended from the plug-in charger, and after the charging controller 220 detects the event, the first power supply path is set to be in a connected state and the second charging path is set to be in a disconnected state, so that the battery 210 supplies power to the external device through the first interface 230 again.
If the first interface 230 is kept plugged into the external device, the second interface 240 is changed from suspended to plugged into the external device, and after the charging controller 220 detects the event, the first power supply path is set to be in an off state and the second power supply path is set to be in a connected state, and the battery 210 supplies power to the external device through the second interface 240. At the same time, the second charging path is set to an off state, preventing current from flowing backward. Although both device interfaces are plugged into external devices, the data transmission in the direction of the second interface 240 is ensured, and the data path in the direction of the first interface 230 is cut off, so that the first power supply path is not necessarily kept connected.
If the first interface 230 is kept plugged with the external device, the second interface 240 is changed from the plugged external device to be suspended, and after the charging controller 220 detects the event, the first power supply path is set to be in a connected state and the second power supply path is set to be in a disconnected state, so that the battery 210 supplies power to the external device through the first interface 230 again.
A fourth type of scenario, change from a hover-plug charger to other states:
if the second interface 240 remains a plug-in charger, the first interface 230 is changed from a floating state to a plug-in charger, and after detecting the event, the charging controller 220 does not respond, so as to ensure that the second interface 240 is used for charging preferentially.
If the second interface 240 remains plugged in the charger, the first interface 230 becomes unsettled from the plugged in charger and does not respond after the charging controller 220 detects the event.
If the second interface 240 remains plugged with the charger, the first interface 230 is changed from suspended to plugged with the external device, and the charging controller 220 does not respond after detecting the event, so as to ensure that the second interface 240 is used for charging preferentially.
If the second interface 240 remains plugged into the charger, the first interface 230 becomes unsettled from the plugged external device, and the charging controller 220 does not respond after detecting the event.
It will be appreciated that if the second interface 240 remains plugged in to the charger, the charge controller 220 does not respond to the state change of the first interface 230, and the first power path and the first charging path remain disconnected at all times.
