In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the electronic device provided by the embodiment of the invention, as shown in fig. 1, the electronic device includes a functional module and a main board with an assembly relationship, that is, the functional module is assembled on the main board, and the functional device can be connected with the main board through pins. The electronic equipment can be a mobile phone, a tablet personal computer and the like, the functional module can be a module which is possibly installed on the electronic equipment in a missed manner or in an unsatisfactory installation mode, the module can be manually installed, and the functional module can be a camera module, a fingerprint module or other modules.
As shown in the schematic structural diagrams of the functional module shown in fig. 2a and fig. 2b, a first detection pin is disposed on the functional module, the first detection pin is communicated with a power pin of the functional module, and as shown in fig. 2b, a resistor may be disposed between the first detection pin and the power pin.
In the schematic structural diagram of the motherboard shown in fig. 3, a second detection pin is disposed on the motherboard, the motherboard corresponds to the functional module, and the second detection pin on the motherboard corresponds to the first detection pin of the functional module, specifically, the number of the first detection pins is N, the number of the second detection pins is N, N is an integer greater than 1, and the first detection pins and the second detection pins are in one-to-one correspondence.
In the electronic device assembling process, if the functional module is correctly assembled on the motherboard, it can be understood that the first detection pins of the functional module are connected with the second detection pins of the motherboard one by one to form a closed loop, for example, there are 4 first detection pins a, b, c, D on the functional module and 4 second detection pins A, B, C, D on the motherboard, and when the functional module is correctly assembled on the motherboard, a and A, b and B, c are connected with D and C, D are connected one by one to form a closed loop. The power supply pin is connected with a power supply on the main board, the power supply on the main board supplies power for the closed loop, and illustratively, the power supply pin can be an iovdd pin, the power supply on the main board can be a 1.8v long power supply, and the voltage value on each second detection pin is larger than a preset threshold value, namely, the voltage value on A, B, C, D is larger than the preset threshold value.
In combination with the above description, the communication state between the first detection pin and the second detection pin is used for determining whether the installation state between the functional module and the motherboard meets the installation requirement when the electronic device is detected, which can be understood that the electronic device can determine whether the installation state between the functional module and the motherboard meets the installation requirement according to the communication state between the first detection pin and the second detection pin when the electronic device is tested.
In one implementation manner, the electronic device may be configured to read a voltage state of the second detection pin, and determine, according to a relationship between the voltage state of the second detection pin and a preset value, whether an installation state between the functional module and the motherboard meets an installation requirement. The second detection pin may also be used to read its own voltage state, e.g. the second detection pin may be a GPIO (General Purpose Input Output, general purpose input/output) interface, which is set to a read state for reading its own voltage state.
Specifically, the electronic device determines the connection state of each second detection pin and each first detection pin according to the relation between the voltage state of each second detection pin and the preset value, and further determines the installation state between the functional module and the main board. Here, the voltage state may be a high level or a low level, and when the electronic device determines that the voltage state is a high level, it determines that the second detection pin is connected with the first detection pin; the voltage state may also be a voltage value, and the electronic device compares the voltage value with a preset threshold value, and determines that the second detection pin is connected to the first detection pin after determining that the voltage value is greater than the preset threshold value.
In the embodiment of the invention, the number of the first detection pins is N, the number of the second detection pins is N, and the electronic equipment is specifically used for determining that the installation state between the functional module and the main board meets the installation requirement when the voltage states of the N second detection pins are determined to meet the preset value; when the voltage states of the M second detection pins are determined to be in accordance with a preset value, determining that the installation state between the functional module and the main board is not in accordance with the installation requirement, wherein M is an integer greater than 1 and less than N; and when the voltage states of the N second detection pins are not in accordance with the preset value, determining that the functional module is not mounted on the main board.

and a second case: if the voltage states of the 2 second detection pins (A, B) are determined to be in accordance with the preset value, and the voltage states of the 2 second detection pins (C, D) are determined to be not in accordance with the preset value, determining that a and A, B are correctly connected with B, and c and C, D are incorrectly connected with D, namely, determining that the functional module is mounted on the main board, wherein the mounting state of the functional module is not in accordance with the mounting requirement;
and a third case: if the voltage states of the 4 second detection pins do not meet the preset value, determining that a, A, b, B, c, C, D and D are both incorrectly connected, and determining that the functional module is not mounted on the motherboard, i.e. the functional module is not mounted in the electronic device.
