Embodiment Construction
[0055] At this stage, during the relay race, the receiver needs to estimate the distance between the receiver and the handover, and start running when the distance between the receiver and the handover is a preset value. When the person taking over the baton and the person passing the baton arrive at the handover point at the same time, the speed of the person taking over the baton is the highest, thereby making the best running results in the relay race.
[0056] Exemplary, such as figure 1 As shown, at time T1, the distance between the successor A and the successor B is D. The receiver A is in a static state, and the receiver B is in a state of motion at the highest speed. At this time, the successor A starts running from a static state, and reaches the maximum speed V of the successor A through acceleration. 1 . Assume that the successor A passes through the uniform acceleration movement with acceleration a and initial velocity 0, and when he reaches the handover point, ...

The embodiment of the invention is applicable to the technical field of terminals, and provides a prompting method, device, equipment and system based on ultra wide band (UWB) communication. The prompting method, device, equipment and system are applied to sending equipment, the sending equipment and receiving equipment are in communication connection through UWB, and the sending equipment sends a first message to the receiving equipment at a first moment, and a second message sent by the receiving equipment is received at the second moment, distance information between the sending equipment and the receiving equipment is obtained according to the first moment, the second moment and the time difference, and prompting information is outputted according to the distance information. The second message is a feedback message of the receiving equipment to the first message; the second message comprises a time difference between the time when the receiving equipment receives the first message and the time when the receiving equipment sends the second message. Therefore, the user can perform the next action according to the more accurate prompting information, and the next action can better meet the expectation of the user.
Description
technical field [0001] The embodiments of the present application relate to the technical field of terminals, and in particular to a prompt method, device, device and system based on ultra-wideband UWB communication. Background technique [0002] In some scenarios, it is necessary to estimate the relative distance between two moving objects first, and then proceed to the next step according to the relative distance between the two objects. For example, in the process of taking over the baton in a relay race, the successor needs to determine the starting time according to the relative distance between him and the handover person, and complete the handover with the handover person within a preset range. [0003] At present, the successor estimates the relative distance from the handover person through visual inspection; since the successor estimates the distance information through visual inspection, the estimated relative distance tends to have large errors, resulting in the ...
