Embodiment Construction
[0014] The specific implementation manners of the present application will be described in further detail below in conjunction with the accompanying drawings.
[0015] The UWB ranging method proposed by this application, such as figure 1 shown, including the following steps:
[0016] Step S11: Determine the measured distance between the beacon and the signal source based on the ranging frequency.
[0017] The UWB distance measuring method that this application proposes is based on such as figure 2 The UWB ranging system shown is realized. The UWB ranging system includes a signal source 1 and a beacon 2. The beacon is composed of a main controller 21, a UWB ranging module 22, a Beidou positioning module 23, a communication module 24 and a motion sensor 25. Wherein the UWB ranging module 22 provides a ranging function, the Beidou positioning module 23 provides longitude and latitude position coordinate information, the motion sensor 25 collects the motion data of the article ...

The invention discloses a UWB (Ultra Wideband) distance measurement method and system. On the basis of distance measurement frequency, an actual measurement distance between a beacon and an information source is determined, and the motion data of the beacon is obtained; updated distance measurement frequency is determined on the basis of the actual measurement distance and the motion data; and thedistance measurement frequency is updated into the updated distance measurement frequency to realize a purpose that next distance measurement is performed on the basis of the updated distance measurement frequency. According to the invention, on the basis of the actual measurement distance between the beacon and the information source and the motion data of a beacon model, the frequency of UWB distance measurement is adjusted, so that the distance measurement frequency is dynamically updated according to an actual distance measurement situation and the motion data; and compared with a way ofusing fixed distance measurement frequency to measure a distance between the beacon and the information source, the dynamically-adjusted distance measurement frequency can not only guarantee timely off normal alarm, but also lower beacon power consumption, and therefore, the technical problem of large beacon power consumption for guaranteeing timely off normal alarm in existing UWB distance measurement is solved.
Description
technical field [0001] The invention belongs to the technical field of carrierless communication, and in particular relates to a UWB ranging method and system. Background technique [0002] With the development of wireless communication technology, the technology of distance measurement using wireless communication has also been developed rapidly. People have an urgent need to prevent the loss of important items and effectively track them after they are lost. Such as exhibition halls, supermarkets, door posts, computer rooms, etc., these places usually store or hold important items, in order to obtain the real-time distance information of these important items from the set position, it is usually necessary to embed wireless distance measuring devices in these important items, and in the device Place the ranging base station at a fixed location. [0003] UWB (Ultra Wideband, ultra-wideband technology) is a brand-new communication technology that is very different from tradit...
