The invention provides a range finding system based on a customized range finding protocol. The range finding system based on a customized range finding protocol includes at least one range finding device, wherein the range finding device is used for performing range finding and communication through UWB (Ultra Wide Band) signals, and performing range finding in a TW-ToF mode; the range finding device includes a processor, a transceiver, an antenna, a setting module, an ID register and a communication interface; the processor is used for data processing; the transceiver is connected with the processor and is also connected with the antenna; the transceiver is used for outputting a range finding request through the antenna, and receiving the range finding requests of other range finding devices through the antenna at the same time; the antenna is used for data transmission; the setting module is connected with the processor; the setting module is used for setting the operating mode of the range finding device; the ID register is a nonvolatile memory, and is used for storing the ID identification numbers of all the range finding devices; and the communication interface is connected with the other range finding devices for performing many-for-one range finding.
Description
technical field [0001] The invention relates to the technical field of ranging systems, in particular to a ranging system based on a self-defined ranging protocol. Background technique [0002] At present, with the rapid increase of data services and multimedia services, people's demand for positioning and navigation is increasing, especially in complex indoor environments, such as airport halls, exhibition halls, warehouses, supermarkets, libraries, underground parking lots and mines etc. It is often necessary to determine the location information of the mobile terminal or its holder, facilities and objects indoors. At present, positioning and ranging mainly include ultrasonic ranging technology, Bluetooth ranging technology, radio frequency identification ranging technology, Wi-Fi ranging technology, etc., but each positioning and ranging method has certain limitations. Multipath effects and non-line-of-sight propagation have a great impact, and at the same time require a...
