Problems solved by technology

[0002] With the diversification of the functions of electronic devices, more and more users have an increasingly strong demand for accurate indoor positioning using electronic devices, and Bluetooth Low Energy (BLE) technology, with its low energy consumption, low cost, and dense layout and other advantages, become the primary choice for accurate indoor positioning; for example, electronic devices use BLE technology to calculate the received signal strength indication (RSSI, Received Signal Strength Indication) value of BLE signals transmitted by other electronic devices, and then estimate their own and distance between other electronic devices in order to control itself to perform corresponding operations based on the estimated distance; however, since the RSSI value also jumps when the electronic device is stationary, the distance value estimated by using this RSSI value is reliable Poor sex

Embodiment 1

[0020] This embodiment provides a control method, specifically, figure 1 It is a schematic diagram of the implementation flow of the control method in the embodiment of the present invention Figure 1 ;like figure 1 As shown, the method includes:

[0021] Step 101: The first electronic device executes a target operation and enters a first working state; wherein, in the first working state, the first electronic device receives and processes a target signal transmitted by a second electronic device;

[0022] In this embodiment, the target operation may specifically be an operation preset by the electronic device. For example, the target operation may be a screen projection operation, that is, the display content of the display screen corresponding to the first electronic device is projected to the second In the electronic device, correspondingly, the first working state may specifically be a state corresponding to when the first electronic device performs a screen projection o...

Embodiment 2

[0037] This embodiment provides a control method, specifically, figure 2 It is a schematic diagram of the implementation flow of the control method in the embodiment of the present invention Figure II ;like figure 2 As shown, the method includes:

[0038] Step 201: The first electronic device executes a target operation and enters a first working state; wherein, in the first working state, the first electronic device receives and processes a target signal transmitted by a second electronic device;

[0039] In this embodiment, the target operation may specifically be an operation preset by the electronic device. For example, the target operation may be a screen projection operation, that is, the display content of the display screen corresponding to the first electronic device is projected to the second In the electronic device, correspondingly, the first working state may specifically be a state corresponding to when the first electronic device performs a screen projectio...

Embodiment 3

[0057] Based on the method described in Embodiment 2, in this embodiment, the moving state of the first electronic device is different, and the matching criteria of the signal transformation characteristics of the target signal and the moving state of the first electronic device are different; specifically land:

[0058] In an embodiment, when the first electronic device is in a first moving state, such as a moving state, the first electronic device detects its own movement change characteristics; the movement change characteristics at least include the first electronic device Relative distance change characteristics with the second electronic device;

[0059] Further, the first electronic device judges whether the signal strength change feature in the signal transformation feature of the target signal matches the relative distance change feature in the movement change feature of the first electronic device, and then determines whether to The signal change characteristic cont...

Abstract

Embodiments of the invention disclose a control method. The control method comprises the following steps that first electronic equipment executes a target operation and enters a first working condition, wherein the first electronic equipment receives and processes a target signal transmitted by second electronic equipment under the first working condition; the first equipment detects signal change characteristics of the target signal received by the first electronic equipment and a moving state of the first electronic equipment, wherein the signal change characteristics at least include signal strength change characteristics; and the first electronic equipment determines whether to control the first operation of the first electronic equipment according to the signal change characteristics. The embodiments of the invention also disclose electronic equipment.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a control method and electronic equipment.
