An embodiment of the present invention provides a device communication method. Referring to FIG. 2 , FIG. 2 is a schematic flowchart of a first embodiment of the device communication method according to the present invention.

In this embodiment, the device communication method includes the following steps:

Step S10: Scan for UWB devices within a preset range, and the UWB devices periodically broadcast their own device information.

It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as smart watches, tablet computers, personal computers, mobile phones, etc., or a device capable of implementing the above Functional electronic equipment, etc. The following uses a smart watch as an example to illustrate this embodiment and the following embodiments.

It can be understood that Ultra Wide Band (UWB) technology is a wireless carrier communication technology. It does not use sinusoidal carrier, but uses nanosecond-level non-sinusoidal narrow pulses to transmit data, so the spectrum it occupies The range is wide, and UWB has data transmission and positioning functions.

In this embodiment, the smart watch periodically scans the UWB devices within the preset range; the smart watch is provided with a UWB module, and the smart watch can realize data transmission and positioning functions through the UWB module, and the preset range can be UWB The data transmission range of the module, for example, the data transmission range of the UWB module is a meter, and the corresponding preset range can be a range with a meter as the radius; the UWB device can be a device equipped with a WUB module, and the UWB device can be a smart watch, Smart terminals such as smart phones; device information may be information that can characterize device characteristics, and device information includes device location information and device identity information.

Step S20: Generate and display a radar map of equipment according to the equipment information obtained through scanning.

It can be understood that the device radar map can be a map marked with device location information and device identity information. The smart watch scans the device information within a preset range according to a preset cycle, and reads the device location information and device identity information from the device information. , according to the device location information, map the device identity information to the blank radar map to obtain the device radar map, and the smart watch updates the device radar map according to the scanned device information at preset intervals; for example: pre-set the blank radar map, the smart watch according to The device information obtained by scanning maps the device location information and device identity information to a blank radar map to obtain a device radar map.

In this embodiment, the smart watch periodically scans the UWB devices within the preset range, and can update the device radar map according to the device information obtained by the current scan, and update the device radar map in real time according to the device information obtained by scanning; in order to reduce energy consumption, The device radar map can also be updated according to the preset scan cycle. For example, if the preset scan cycle is a, the device radar map is updated every scan cycle a; the update method can be set according to the specific scenario, for example, the device radar map is refreshed every 500ms , to ensure the accuracy of the scanned UWB device; this embodiment is not limited here.

Step S30: Determine the target UWB device selected by the user based on the device radar map, and read the target device information of the target UWB device.

It can be understood that the target UWB device can be a UWB device selected by the user on the device radar map that requires data communication. The device identity and device orientation of the UWB device will be visually displayed on the device radar map. The user can base on the device identity and device orientation. to select the target UWB device; after the user selects the target UWB device, the smart watch reads the target device information corresponding to the target UWB device.

In order to scan the device information transmitted by the UWB device in time, set the smart watch The scan time in the scan cycle is longer than the interval for UWB devices to transmit device information. For example, the interval for UWB devices to transmit device information is 101ms. You can set the scan time in the scan cycle of the smart watch to 120ms, and the smart watch scans once every 500ms. For the UWB device, each scan time is 120ms, so that the scan time of the smart watch covers at least one transmission cycle of the UWB device.

It should be noted that, in the traditional UWB-based data transmission method, both sides of the interaction need to know each other's existence, the data receiving end must always be in the receiving mode, and the data sending end must always be in the sending mode, resulting in high power consumption of the device. Use low power consumption mode to scan UWB devices, and establish a communication connection according to the target device information of the target UWB device. The information channel will only be established when needed. While realizing data communication in a small area without a network, the device function is reduced. consumption.

The watch determines the device identity information and device location information of the UWB device based on the device information obtained by scanning, maps the device identity information and device location information to a blank radar map to generate a device radar map, and displays the device radar map, with preset scan intervals Periodically update the displayed device radar map. If the user selects the target UWB device on the device radar map, read the target device information of the target UWB device, and perform communication verification with the target UWB device according to the target device information. When the communication verification passes, Establish a communication connection with the target UWB device.

Further, in order to generate a device radar map based on the scanned device information, the step S40 includes: determining the device location, device distance and device identity information of each UWB device according to the device information obtained by scanning; Generate and display a device radar map based on the device distance and the device identity information.

The relative position and device distance map the device identity information to a blank radar map to obtain a device radar map.

It should be noted that this embodiment adopts UWB technology, utilizes the positioning function of UWB, and displays the device ID of the UWB device on the smart watch through the device radar map. Since UWB positioning has centimeter-level positioning accuracy, users can use it based on The device ID, device location, and device distance displayed on the device radar map can determine the correspondence between the device ID on the device radar map and the people within the preset range. The user can select the target UWB device on the device radar map through this correspondence. The smart watch establishes a communication connection with the target UWB device according to the target device information of the target UWB device to exchange data and files.

The UWB device generates device information according to the preset data format and the user-defined device ID. The preset data format can refer to Table 1, "HEAD" in the table To represent the field of the data header, the storage data "0x5A" is used to represent the data header, and the storage space of "0x5A" is 1 byte (1 byte); "LENGTH" is the field representing the length of the ID segment, and the stored data "ID segment length N "The byte length used to represent the device ID is N, and the storage space of "ID segment length N" is 1 byte (1 byte); "ID" is the field representing the device ID, and the stored data "device ID" is used to represent Device identification number, the storage space of "device identification number" is N bytes (N byte), for example, the device identification number can be Jack, Jim, etc.; CRC (Cyclic Redundancy Check), that is, cyclic redundancy check, " CRC" is a field representing the cyclic redundancy check, and the stored data "check of the ID segment" is used to represent the cyclic redundancy check code, and the storage space of the cyclic redundancy check code is 2 bytes (2byte); for example The smart watch scans UWB devices within the pre-range, and scans the device information transmitted by 4 UWB devices. The device IDs read from the device information are: Jack, Jim, Tom and Lucy, determined according to the device location of each UWB device Each UWB device is relative to the azimuth and device distance of the device, and the device ID is mapped to a blank radar map according to the azimuth and device distance to obtain the device radar map.
