The number of the target devices is not unchanged, and therefore, the number of the indication signals that need to be generated each time is also different. This example takes the display lamps as an instance for illustration.

If the displayable number of the display lamps is 3, the displayable colors are 3, at this time, if the number of the target devices is less than or equal to 3, for example, specifically being 3, indication signals with different displayable numbers or colors only may be generated, for example, the displayable number of the three indication signals are 1, 2 and 3 respectively, or the displayable colors of the three indication signals are red, green and blue respectively. If the number of the target devices is greater than 3, for example, specifically being 4, indication signals that combine different displayable numbers and colors may be generated to enable the indication operations corresponding to the indication signals to be different, for example, indicator lamps lightened by four indication signals are 1 red, 2 reds, 3 reds and 1 blue respectively. It may be understood that this example only describes one application scenario, and the specific displayable numbers, displayable colors and combinations between the numbers and the colors may be set based on actual demands.

Different target devices receive different indication signals and execute different indication operations based on the indication signals, and the user may clear identities of the target devices through the indication operations. In order to further facilitate distinguishing by the user, after sending the indication signals to the corresponding target devices, an association relationship between each target device and the corresponding indication operation may be displayed, so that the user identifies the target device by comparing the association relationship.

In this example, the different indication operations are displayed for the different target devices, so that the user can identify the target device based on the different indication operations when the user cannot identify the target device through the appearance.

In some embodiments, in a fourth example of the device identification method of the present disclosure provided based on the third example of the present disclosure, after step S33, the method includes steps:

- step S34, a real-time image of each target device is acquired, and an indication identifying operation is executed on the real-time image;
- step S35, in a case that the indication identifying operation identifies the indication operation, a current device corresponding to the indication operation is matched among the target devices; and
- step S36, unique identification information of the current device is acquired, and the unique identification information is displayed in a display position associated with the current device.

The real-time image may be collected through an image collection device such as a camera; and when the real-time image is collected, the real-time image is displayed in real time.

The indication identifying operation is an operation that identifies the indication operation. It may be understood that when the indication operation is a visually sensitive operation, such as lamplight and display screen displaying, the real-time image is collected and subjected to image identification; and when the indication operation is an auditory sensitive operation, such as sound, audio information is collected and subjected to sound identification. This example takes the visually sensitive operation as an instance, and the auditory sensitive operation may be executed analogically, which will not be repeated.

It may be understood that before sending the indication signal to the target device, an association relationship between the indication operation corresponding to the indication signal and the target device has been stored, after the target device executes the indication operation corresponding to the indication signal, the indication operation executed by the target device is identified, and the target device corresponding to the identified indication operation is matched based on the stored association relationship.

When it is connected with the target device, the relevant information of the target device has been acquired. Therefore, after determining the target device, it is necessary to obtain information that can represent uniqueness of the target device to enable the user to clear the target device. In some embodiments, the unique identification information is used as the information that represents the uniqueness of the target device. It needs to be noted that the unique identification information is used for representing the uniqueness of the target device; based on different application scenarios, ranges for selecting the unique identification information are different, for example, when there are a plurality of connected target devices, and the user does not set unique information for the different target devices, identifiers preset by the devices for representing unique identities of the devices, such as unique device coding, serial numbers, and MAC addresses of the target devices, are used as the unique identification information. When the user sets unique information for the different target devices, such as device names set by the user, except for the above identifiers preset by the devices for representing the unique identities of the devices, the information set by the user may further be used as the unique identification information. It may be understood that the selection basis for the unique identification information is the information that there is a difference between the target devices.

After acquiring the unique identification information of the target device, in order to enable the user to quickly clear the identity of the target device, the unique identification information is displayed. In some embodiments, the unique identification information is displayed in the displayed real-time image; and when the target device is recognized in the real-time image, the target device is positioned in the real-time image, a position relative to the target device in the real-time image may be preset as a display position associated with the target device, such as an upper part, a lower part, a left side, a right side and a middle part of the target device. When there are the plurality of target devices in the real-time image, the unique identification information of each target device is displayed in the display position corresponding to each target device, and the user can identify the plurality of target devices at the same time through the displayed unique identification information.

In this example, the unique identification information of the target devices is displayed in the display positions associated with the target devices, so that the user can quickly and accurately identify the target devices.

In some embodiments, in a fifth example of the device identification method of the present disclosure provided based on the first example of the present disclosure, step S20 includes steps:

- step S21, the unique identification information of each target device is acquired, and all pieces of unique identification information are displayed;
- step S22, a confirm instruction returned based on the unique identification information is received, and a designated device corresponding to the confirm instruction is determined among the target devices; and
- step S23, gyroscope data and a signal intensity of the designated device are acquired, and a guidance operation is performed on the designated device according to the gyroscope data and the signal intensity.

When a specific target device, namely the designated device, is found in the plurality of target devices, if there are too many target devices, it is troublesome for the user to compare the indication operations one by one, and there may even be a situation that the user cannot know the location of the specific target device, which further affects the identification of the user. In this example, the unique identification information of each target device is displayed, the user selects the unique identification information to trigger the confirm instruction, and after receiving the confirm instruction, the designated device among the target devices is determined based on the confirm instruction.

Since the mobile phone is connected with the target device, a signal intensity of connection may be determined based on a connection mode, if it is a Bluetooth connection, the signal intensity of Bluetooth is determined, and if it is a WiFi connection, the signal intensity of WiFi is determined. The gyroscope data is used for representing a device position of the mobile phone, in conjunction with the device positions of the mobile phone at different moments and the signal intensities corresponding to the different device positions, a position relationship between the target device and the mobile phone may be determined, specifically:

- step S32 includes steps:
- step S231, a device moving trajectory is determined according to the gyroscope data, and signal intensities corresponding to different device positions in the device moving trajectory are determined;
- step S232, a distance between each device position and the designated device is determined according to the signal intensity corresponding to each device position, and a relative position of the designated device is determined according to the distance between each device position and the designated device; and
- step S233, indication information is generated according to the relative position, and the indication information is displayed.

The device positions of the mobile phone at different moments may be obtained through changes of the gyroscope data; the device moving trajectory is a set of the device positions at successive different moments; and a distance relationship between different device positions and the designated device may be determined through the signal intensities corresponding to different device positions. In some embodiments, the higher the corresponding signal intensity, the closer the device position to the designated device, and the lower the corresponding signal intensity, the farther the device position to the designated device; and a relative position between the designated device and the mobile phone may be obtained based on each device position and a relative far and near relationship between each device position and the designated device.

After determining the relative position between the designated device and the mobile phone, it is necessary to guide the position of the designated device to the user; and the indication information is used for indicating the position of the designated device, and the indication information includes, but is not limited to maps, text or patterns. For example, a simplified map is generated according to the relative position, and the relative position between the device and the mobile phone is marked in the map. For another example, the indication information corresponding to a current facing direction of the mobile phone is determined according to the relative position, such as turning 30 degrees to the right, going straight, and going backwards. For another example, an indication identifier corresponding to the current facing direction of the mobile phone is determined according to the relative position, such as a right arrow and a straight arrow. The user may be guided to the position of the designated device through the indication information.

In this example, the relative position between the designated device and the mobile phone is determined, and the indication information corresponding to the relative position is displayed, so that the user can be guided to the position of the designated device, without the need for self comparison of the user, which is convenient for the user to use.

It needs to be noted that, for the sake of simple description, the above method examples are all expressed as a series of action combinations, but those of ordinary skill in the art should understand that the present disclosure is not limited by the described action sequences because according to the present disclosure, some steps may be performed in other sequences or at the same time.
