In this embodiment, the device communication method includes the following steps:
step S10: and scanning UWB equipment in a preset range, wherein the UWB equipment periodically broadcasts own equipment information.
It should be noted that, the execution body of the embodiment may be a computing service device having functions of data processing, network communication and program running, such as a smart watch, a tablet computer, a personal computer, a mobile phone, or an electronic device capable of implementing the above functions. The present embodiment and the following embodiments will be described by taking a smart watch as an example.
It can be understood that Ultra Wideband (UWB) technology is a wireless carrier communication technology, which does not use a sinusoidal carrier, but uses non-sinusoidal narrow pulses of nanosecond level to transmit data, so that the UWB technology occupies a Wide spectrum range, and has data transmission and positioning functions.
In this embodiment, the smart watch periodically scans UWB devices within a preset range; the intelligent watch is internally provided with the UWB module, the intelligent watch can realize data transmission and positioning functions through the UWB module, the preset range can be the data transmission range of the UWB module, for example, the data transmission range of the UWB module is a meters, and the corresponding preset range can be the range taking a meters as the radius; the UWB equipment can be equipment provided with a WUB module, and the UWB equipment can be intelligent terminals such as intelligent watches, intelligent mobile phones and the like; the device information may be information capable of characterizing a device characteristic, the device information including device location information and device identity information.

It can be understood that the device radar map may be a map with device location information and device identity information identified, the smart watch scans the device information within a preset range according to a preset period, reads the device location information and the device identity information from the device information, maps the device identity information to a blank radar map according to the device location information, and obtains the device radar map, and updates the device radar map according to the scanned device information at preset intervals; for example: and presetting a blank radar map, and mapping the equipment position information and the equipment identity information to the blank radar map by the intelligent watch according to the equipment information obtained by scanning to obtain the equipment radar map.
In this embodiment, the smart watch periodically scans UWB devices within a preset range, and may update a device radar map according to device information obtained by current scanning, and update a device radar map according to the device information obtained by scanning in real time; in order to reduce the energy consumption, the radar map of the equipment can also be updated according to a preset scanning period, for example, the preset scanning period is a, and the radar map of the equipment is updated once at intervals of a scanning periods; an updating mode can be set according to a specific scene, for example, a radar map of the device is refreshed every 500ms, so that the accuracy of scanned UWB devices is ensured; the present embodiment is not limited herein.
Step S30: and determining target UWB equipment selected by a user based on the equipment radar map, and reading target equipment information of the target UWB equipment.
It can be understood that the target UWB device may be a UWB device selected by a user on a device radar map to perform data communication, where the device identity and the device orientation of the UWB device are visually displayed on the device radar map, and the user may select the target UWB device based on the device identity and the device orientation; after the user selects the target UWB device, the intelligent watch reads the target device information corresponding to the target UWB device.

In this embodiment, the smart watch performs communication verification with the target UWB device according to the target device information, and establishes communication connection with the target UWB device when the communication verification passes.
It should be understood that, since the UWB device periodically transmits its own device information, if the smart watch scans during the period when the UWB device stops transmitting, the smart watch may not be able to scan the device information, in order to be able to scan the device information transmitted by the UWB device in time, the scan time of the smart watch in the scan period is set to be longer than the interval duration of the UWB device transmitting the device information, for example: the interval duration of the device information emission of the UWB device is 101ms, the scanning duration in the intelligent watch scanning period can be set to be 120ms, the intelligent watch scans the UWB device once at intervals of 500ms, and the scanning duration of each time is 120ms, so that the scanning duration of the intelligent watch at least covers one emission period of the UWB device.
It should be noted that, in the conventional UWB-based data transmission manner, the two interacting parties need to know each other, the data receiving end needs to be always in a receiving mode, and the data transmitting end needs to be always in a transmitting mode, so that the power consumption of the device is large.
In a specific implementation, for example: the intelligent watch is provided with a UWB module, the data communication range of the UWB module is 15 meters, the intelligent watch scans UWB equipment within the radius range of 15 meters to receive equipment information transmitted by the UWB equipment, the intelligent watch determines equipment identity information and equipment position information of the UWB equipment according to the equipment information obtained by scanning, the equipment identity information and the equipment position information are mapped to a blank radar map to generate an equipment radar map, the equipment radar map is displayed, the displayed equipment radar map is updated at intervals of preset scanning period, if a user selects target UWB equipment on the equipment radar map, target equipment information of the target UWB equipment is read, communication verification is carried out between the target equipment information and the target UWB equipment according to the target equipment information, and communication connection is established between the intelligent watch and the target UWB equipment when the communication verification passes.

In this embodiment, the UWB device generates device information according to the device identity information and a preset data format, and periodically transmits the device information, where the smart watch determines a device relative position and a device distance according to its device position and the scanned device position, and maps the device identity information to a blank radar map according to the device relative position and the device distance, so as to obtain a device radar map.
It should be noted that, in this embodiment, the UWB technology is adopted, the device ID of the UWB device is displayed on the smart watch by using the positioning function of the UWB device in a manner of a device radar map, and because the positioning accuracy of the UWB device has a centimeter level, the user can determine the correspondence between the device ID on the device radar map and a person in a preset range based on the device ID, the device position and the device distance displayed on the device radar map, and the user can select the target UWB device on the device radar map through the correspondence, and the smart watch establishes communication connection with the target UWB device according to the target device information of the target UWB device, so as to exchange data and files.
