[0014] The data of the distance and the azimuth angle are mapped into a coordinate vector, the center of the screen of the television device end is taken as the origin of the coordinate vector, and the diagram of the coordinate vector is displayed on the television device end.

[0015] As a preferred scheme of the application, by displaying the diagram of the coordinate vector, the user can more intuitively see the position and the angle of the remote controller, which is beneficial to more quickly find the remote controller, and further improves the convenience of finding the remote controller.

[0016] Preferably, the remote controller position determination method for the smart television disclosed by the application further comprises the following steps before the S1:

It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0034] Embodiment 1:

[0035] Reference Figure 1 and Figure 2 As shown in the figure, the embodiment discloses a remote controller position determination method for a smart TV, comprising the following steps:

[0036] S1, configuring a first UWB module and a first communication module at the remote controller device end; configuring a second UWB module, a second communication module and a display auxiliary module at the TV device end;

[0037] S2, when a user searches for the remote controller device end through the TV device end, the second communication module and the first communication module establish a communication connection, and send a first instruction to the first communication module, thereby controlling the working mode of the first UWB module and the first communication module;

[0038] S3, according to the first instruction, the first UWB module and the second UWB module establish a UWB connection, and when receiving the first reply instruction of the first communication module, the distance between the first UWB module and the second UWB module is measured through the second UWB module, and the azimuth angle of the first UWB module with the second UWB module as the center point is measured;

[0039] S4, the second UWB module sends the distance and the azimuth angle to the display auxiliary module;

[0040] S5, the distance and the azimuth angle are displayed on the TV device end through the display auxiliary module.

[0041] Specifically, S4 further comprises the following steps: mapping the data of the distance and the azimuth angle into a coordinate vector, and taking the center of the screen of the TV device end as the origin of the coordinate vector, and displaying the diagram of the coordinate vector on the TV device end. The diagram of the coordinate vector of the present application can be realized through the display control of the display auxiliary device or the TV device, for example, through the rendering function, the coordinates are converted into the coordinates on the screen through projection transformation, which is used for displaying the vector or direction indication; or the coordinate values of the data points are directly drawn on the TV screen to form a vector diagram or a point cloud diagram, which may involve the mapping and scaling of the coordinate axes.

[0042] It should be noted that the first and second of the present application are not specifically explained in order and numerical value, and are only used for distinguishing description. The UWB measurement method is understood as a method for measuring the target azimuth angle, and a method for estimating the incident direction of the radio wave at the receiving end. For example, the distance between the UWB devices is calculated by calculating the time difference of the signal propagation between the devices, and the angle between the UWB devices is calculated by measuring the phase difference of the signal arriving at the double antenna array.

[0043] It can also be implemented, for example, as follows: the receiving node of the multi-antenna array of the UWB interface, at least two antennas form a baseline with a known length, when a plane wave is incident from a certain azimuth angle, the path length of the electromagnetic wave arriving at the two antennas will appear a small difference; the UWB receiving chip samples the channel impulse response of each antenna, extracts the phase of the direct path, and the phase difference of the two antennas can be inversely solved to obtain the azimuth angle. The bandwidth of UWB is extremely wide, and the correlation peak is sharp. Even in a severe multipath indoor environment, the direct path phase can be reliably locked, and the angle estimation accuracy is ensured.

[0044] Specifically, before the S1, the following steps are further included: when the remote controller device end is used for the first time, a communication broadcast is periodically sent through the first communication module, and a television characteristic value is configured in the communication broadcast; the television characteristic value is used to mark the matching value of the remote controller device end and the television device end; the communication broadcast is continuously scanned through the second communication module, and the scanned communication broadcast is parsed to obtain the corresponding television characteristic value; if the matching value of the television characteristic value meets the matching requirement, a connection is established with the first communication module, and the corresponding remote controller ID is stored.

[0045] The communication connection of the present application can be a Bluetooth connection or a network protocol connection. Specifically, the second communication module and the first communication module establish a communication connection, which specifically includes the following steps: the second communication module sends a Bluetooth broadcast to the first communication module, and the second communication module transmits data to the first communication module through the Bluetooth protocol.

[0046] Specifically, the S3 further includes the following steps: after the distance and the azimuth angle are measured, a second instruction is sent to the first communication module, and then the working mode of the first UWB module is controlled to be the end measurement mode.
