The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk storage. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

Those skilled in the art will appreciate that the structure shown in FIG. 1 does not constitute a limitation on the device communication device, and may include more or fewer components than shown in the figure, or a combination of certain components, or a different arrangement of components.

In the device communication device shown in FIG1 , the network interface 1004 is mainly used to communicate with the network server. The user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the device communication device of the present invention can be set in the device communication device, and the device communication device calls the device communication program stored in the memory 1005 through the processor 1001, and executes the device communication method provided in the embodiment of the present invention.

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

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

Step S10: Scanning UWB devices within a preset range, wherein the UWB devices periodically broadcast their own device information.

It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a smart watch, a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, etc. The following takes 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 a sinusoidal carrier, but instead uses nanosecond non-sinusoidal narrow pulses to transmit data. Therefore, it occupies a wide spectrum range. UWB has data transmission and positioning functions.

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

Step S20: Generate and display a device radar map based on the device information obtained by 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 period, reads the device location information and 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. The smart watch updates the device radar map according to the scanned device information at a preset interval; for example: a blank radar map is pre-set, and the smart watch The watch maps the device location information and device identity information to a blank radar map based on the device information obtained through scanning to obtain a device radar map.

In this embodiment, the smart watch periodically scans UWB devices within a preset range, and can update the device radar map according to the device information currently obtained by the scan, and update the device radar map in real time according to the device information obtained by the scan; in order to reduce energy consumption, the device radar map can also be updated according to a preset scanning period. For example, if the preset scanning period is a, the device radar map is updated every a scanning period; 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 devices; this embodiment is not limited here.

Step S30: determining a target UWB device selected by the user based on the device radar map, and reading target device information of the target UWB device.

It can be understood that the target UWB device can be a UWB device that the user selects on the device radar map and needs to communicate data. The device radar map will visually display the device identity and device location of the UWB device, and the user can select the target UWB device based on the device identity and device location; after the user selects the target UWB device, the smart watch reads the target device information corresponding to the target UWB device.

Step S40: establishing a communication connection with the target UWB device according to the target device information.

In this embodiment, the smart watch performs communication verification with the target UWB device according to the target device information, and establishes a communication connection with the target UWB device when the communication verification passes.

It should be understood that since UWB devices periodically transmit their own device information, if the smart watch scans during the period when the UWB device stops transmitting, it 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 scanning duration of the smart watch within the scanning cycle is set to be greater than the interval duration of the UWB device transmitting device information. For example: the interval duration of the UWB device transmitting device information is 101ms, the scanning duration within the scanning cycle of the smart watch can be set to 120ms. The smart watch scans the UWB device once every 500ms, and the scanning duration each time is 120ms, so that the scanning duration 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, the two interacting parties need to know each other's existence, the data receiving end needs to be in the receiving mode all the time, and the data sending end needs to be in the sending mode all the time, resulting in high power consumption of the devices. This embodiment uses a low-power mode to scan UWB devices and establish a communication connection based on the target device information of the target UWB device. The information channel is established only when needed, which reduces the device power consumption while realizing data communication in a small range without a network. Power consumption.

In a specific implementation, for example: a UWB module is provided in a smart watch, and the data communication range of the UWB module is 15 meters. The smart watch scans UWB devices within a radius of 15 meters to receive device information transmitted by the UWB devices. The smart watch determines the device identity information and device location information of the UWB device based on the device information obtained by the scan, maps the device identity information and the device location information to a blank radar map to generate a device radar map, and displays the device radar map. The displayed device radar map is updated at preset scanning period intervals. If the user selects a target UWB device on the device radar map, the target device information of the target UWB device is read, and communication verification is performed with the target UWB device based on the target device information. When the communication verification passes, a communication connection is established with the target UWB device.

Furthermore, 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; generating and displaying the device radar map according to the device location, the device distance and the device identity information.

It is understandable that UWB itself has a positioning function. When transmitting device information, the UWB device will also transmit its own device location. The device distance can be determined based on the device location and its own device location; the device identity information can be information that can identify the device identity, such as device identity information including device ID, device number, device identity identification number, etc.

In this embodiment, the UWB device generates device information based on the device identity information and a preset data format, and periodically transmits the device information. The smart watch determines the relative position and distance of the device based on its own device position and the scanned device position, and maps the device identity information to a blank radar map based on the relative position and distance of the device to obtain a device radar map.

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

In the specific implementation, please refer to Figure 3, which is a schematic diagram of the device radar map. Generate device information according to the preset data format and the device ID defined by the user, wherein the preset data format can refer to Table 1, in which "HEAD" is a field representing the data header, and the stored data "0x5A" is used to represent the data header, and the storage space of "0x5A" is 1 byte; "LENGTH" is a field representing the length of the ID segment, and the stored data "ID segment length N" is used to represent that the byte length occupied by the device ID is N, and the storage space of "ID segment length N" is 1 byte; "ID" is a field representing the device ID, and the stored data "device ID" is used to represent the device identification number, and the storage space of "device identification number" is N bytes, for example, the device identification number can be Jack, Jim, etc.; CRC (Cyclic Redundancy "CRC" is a field representing the cyclic redundancy check, and the stored data "check of ID segment" is used to represent the cyclic redundancy check code, and the storage space of the cyclic redundancy check code is 2 bytes; for example, a smart watch scans UWB devices within a pre-range, and scans device information transmitted by 4 UWB devices. The device IDs read from the device information are: Jack, Jim, Tom and Lucy, respectively. The azimuth and device distance of each UWB device relative to the device are determined according to the device position of each UWB device, and the device ID is mapped to a blank radar map according to the azimuth and device distance to obtain a device radar map.

Table 1

This embodiment scans UWB devices within a preset range, and the UWB devices periodically broadcast their own device information; generates and displays a device radar map based on the device information obtained by scanning; determines the target UWB device selected by the user based on the device radar map, and reads the target device information of the target UWB device; and establishes a communication connection with the target UWB device based on the target device information. The present invention generates and displays a device radar map using the data transmission and positioning functions of UWB technology, determines the target device information based on the target UWB device selected by the user on the device radar map, and establishes a communication connection with the target UWB device based on the target device information, thereby realizing data communication between smart terminals without a network.

Refer to FIG. 4 , which is a flow chart of a second embodiment of a device communication method according to the present invention.

Based on the above first embodiment, in this embodiment, step S40 includes:

Step S401: Generate a verification data packet based on the target device information and send the verification data The packet is sent to the target UWB device.

It is understandable that the verification data packet may be a data packet for identity authentication during the process of establishing a communication connection, and the verification data packet is broadcast within a preset range so that the target UWB device can scan the verification data packet.

Step S402: upon receiving a response data packet fed back by the target UWB device based on the verification data packet, establishing a communication connection with the target UWB device is completed.

It can be understood that the response data packet can be a data packet generated by the target UWB device based on the target device ID and a preset data format. After receiving the verification data packet, the target UWB device can parse its own device ID from the verification data packet. The target UWB device sends a response data packet containing its own device ID. After receiving the response data packet, the smart watch completes the establishment of a communication connection with the target UWB device.

In a specific implementation, the smart watch generates a verification data packet based on the target device information and broadcasts the verification data packet within a preset range so that the target UWB device can scan and obtain the verification data packet. The smart watch receives a response data packet fed back by the target UWB device based on the verification data packet. When the smart watch receives the response data packet fed back by the target UWB device, it completes the establishment of a communication connection with the target UWB device.

Furthermore, in order to establish a communication connection with a target UWB device, a verification data packet is generated according to the target device information and the verification data packet is sent to the target UWB device, including: reading the target device identity information from the target device information, and generating a verification data packet according to the target device identity information and a preset data format; and broadcasting the verification data packet to the target UWB device through UWB technology.

In a specific implementation, for example, if the target identity information is a device ID, the smart watch reads the device ID from the device information, generates a verification data packet according to the device ID and a preset data format, and when the verification data packet is generated, broadcasts the verification data packet within a preset range so that the target UWB device can scan the verification data packet.

Furthermore, in order to enable the target UWB device to receive the broadcast verification data, the verification data packet is broadcast to the target UWB device through UWB technology, including: when the verification data packet is generated, the verification data packet is continuously broadcast for a first preset duration through UWB technology to send the verification data packet to the target UWB device, and the first preset duration is greater than the scanning interval duration of the target UWB device.

In a specific implementation, for example, if the scanning interval of the target UWB device is 5ms, the first preset time can be set to 10ms. The user selects the target UWB device based on the device radar map. The smart watch obtains the target device information of the target UWB device, reads the target device ID from the target device information, generates a verification data packet according to the preset data format and the target device ID, and broadcasts the verification data packet within a preset range for 10ms. After receiving the verification data packet, the target UWB device transmits a response data packet containing its own device ID. When the smart watch receives the response data packet, it completes the establishment of the communication connection.

This embodiment generates a verification data packet according to the target device information, and sends the verification data packet to the target UWB device; when receiving a response data packet fed back by the target UWB device based on the verification data packet, the communication connection is established with the target UWB device. This embodiment broadcasts the verification data generated according to the target device information of the target UWB device to the target UWB device, and the target UWB device transmits a response data packet based on the verification data packet. When the response data packet is scanned, the communication connection is established, realizing short-distance communication without a network.

Refer to FIG. 5 , which is a flowchart of a third embodiment of a device communication method according to the present invention.

Based on the above embodiments, in this embodiment, after step S40, the method further includes:

Step S50: When the communication connection is established, switching to full-duplex mode, and performing data communication in duplex mode with the target UWB device based on the communication connection.

In this embodiment, in order to reduce energy consumption, the data transmission mode of the smart watch is half-duplex mode before establishing a communication connection with the target UWB device, and switches to full-duplex mode when the communication connection with the target UWB device is established.

Furthermore, in order to reduce device energy consumption, after step S50, the method further includes: when data communication ends, entering standby mode, and sending an end instruction to the target UWB device, so that the target UWB device enters standby mode upon receiving the end instruction.

In a specific implementation, when data communication ends, the smart watch enters standby mode and sends an end instruction to the target UWB device. When the target UWB device receives the end instruction, it displays data communication end information and enters standby mode.

This embodiment switches to full-duplex mode when the communication connection is established, and performs duplex mode data communication with the target UWB device based on the communication connection. This embodiment switches to full-duplex mode when the communication connection with the target UWB device is established, while ensuring the quality of data communication At the same time, it reduces the energy consumption of the equipment.

In addition, an embodiment of the present invention further provides a storage medium, on which a device communication program is stored. When the device communication program is executed by a processor, the steps of the device communication method described above are implemented.
