Abstract

The invention discloses a UWB time slot scheduling system and method applied in a vehicle welcome system. By monitoring the UWB signals around the vehicle, the UWB positioning unit and the corresponding digital vehicle are automatically arranged according to the time of the monitored UWB signal. The UWB signal interaction time slot between the keys; the UWB positioning unit and the corresponding digital car key communicate with the UWB signal according to the arranged time slot, which can avoid the UWB signal sent by other peripheral devices and solve the problem of multiple The interference problem between the car and multiple digital car keys frequently transmitting and receiving UWB signals, so as to avoid interference when the digital car key is used around the vehicle, and improve the user experience when using the digital car key. The invention comprehensively considers the interference of the own vehicle and surrounding UWB signals, and can realize the automatic scheduling of the time slots of the own vehicle, thereby avoiding interference and achieving a better welcoming effect.

Description

technical field [0001] The invention relates to the field of vehicle welcome systems, in particular to a UWB time slot scheduling system and method applied in the vehicle welcome system. Background technique [0002] With the rapid development of mobile terminals, the Internet of Things, and the Industrial Internet, cars are becoming more intelligent, and vehicle unlocking has gradually changed from the traditional mechanical car key unlocking method to a more convenient and intelligent digital car key. When the owner of the car is located at different positions and distances around the car, how to provide welcome service according to the location of the car key has become a problem that people pay more attention to. [0003] In the prior art, there are many welcome solutions based on any combination of UWB, NFC, and Bluetooth. However, when using UWB technology to locate or measure the distance of the digital car key, the digital car key and the pre-arranged anchor node on ...
