At this time, the remote control device is in a state that can be searched by the controlled device, and in this state, the remote control device can transmit the request data.
In another example, the remote control device is in a use state, and request data can be sent through a set trigger condition to be connected with the controlled device through Bluetooth. The trigger conditions may be, for example: a certain time interval is met, or the distance from the controlled equipment meets a certain condition.
S2102 receives a feedback message of the controlled device based on the request data, and determines that the controlled device is in a connection state with the controlled device.
In this step, when the controlled device determines that the request data meets the preset condition, the controlled device can be bound and connected with the remote control device, and sends a corresponding feedback message to inform that the remote control device is currently in a connected state.
When the remote control device is in a connected state, the UWB module of the remote control device can receive the impulse communication signal transmitted by the UWB antenna component of the controlled device.
Therefore, the position mark is displayed on the controlled device, and after the remote control device is aligned with the position mark, according to the signal transceiving parameters of the UWB module in the remote control device, for example: the UWB module of the remote control device receives the pulsed communication signal from the UWB antenna assembly and transmits a pulsed feedback signal. The relative orientation of the remote control device and the location identity is determined from the transmitted and received signals.
