Currently, manufacturers of different UWB devices (such as mobile phones, smart watches, etc.) generally adopt respective UWB protocols for positioning and data communication, and therefore, the protocols supported by the UWB devices of different manufacturers are not generally uniform. Based on this, when UWB terminal devices (such as mobile phones, POS machines, access control systems, and the like) perform UWB communication with UWB devices, the UWB terminal devices need to use specific firmware that supports UWB protocols used by the UWB devices. If the UWB terminal equipment is compatible with UWB equipment of different manufacturers, the information such as the brand of the UWB equipment needs to be determined in advance in the using process, and then the corresponding software version is selected manually, so that normal UWB positioning and communication can be carried out, and the use is inconvenient.
In order to solve the problem of the prior art, embodiments of the present application provide a data communication method, apparatus, device, and computer storage medium. The following first describes a data communication method provided in an embodiment of the present application.
The data communication method provided by the embodiment of the application can be applied to the data communication system shown in fig. 1. As shown in fig. 1, the data communication system may include a first device 101 and a second device 102, wherein the first device 101 is a UWB terminal device, such as a POS machine, an access control system, a mobile phone, etc., including a first bluetooth module 1011 and a first ultra-wideband module 1012, and the second device 102 is a UWB device, such as a mobile phone, a smart watch, etc., including a second bluetooth module 1021 and a second ultra-wideband module 1022. The first device 101 and the second device 102 can perform bluetooth communication via the first bluetooth module 1011 and the second bluetooth module 1021, and can perform ultra-wideband communication via the first ultra-wideband module 1012 and the second ultra-wideband module 1022.
Referring to fig. 2, it is a diagram of information interaction when the data communication system shown in fig. 1 performs data communication by using the data communication method provided in the embodiment of the present application. As shown in fig. 2, a data communication method provided in an embodiment of the present application may include the following steps:
s21, the first device establishes Bluetooth communication connection with the second device before carrying out ultra-wideband communication with the second device.
And S22, the first equipment acquires the ultra-wideband protocol information of the second equipment based on the Bluetooth communication connection with the second equipment.
S23, the first device determines a target ultra-wideband communication protocol corresponding to the ultra-wideband protocol information from a plurality of preset ultra-wideband communication protocols.
S24, the first device establishes an ultra-wideband communication connection with the second device based on a target ultra-wideband communication protocol.
Specific implementations of the above steps will be described in detail below.
According to the data communication method provided by the embodiment of the application, before the first device and the second device carry out ultra-wideband communication, the first device and the second device establish Bluetooth communication connection, the first device obtains ultra-wideband protocol information of the second device based on the Bluetooth communication connection, and then the first device determines a target ultra-wideband communication protocol corresponding to the ultra-wideband protocol information from a plurality of preset ultra-wideband communication protocols, so that the ultra-wideband communication connection is established with the second device based on the target ultra-wideband communication protocol. According to the embodiment of the application, when the first device and the second device are in UWB communication connection, the UWB protocol information of the second device is obtained through Bluetooth communication, the UWB protocol supported by the second device is automatically determined according to the UWB protocol information, manual selection of a user is not needed, the operation is simple, and the use is more convenient.
Specific implementations of the above steps are described below.
First, introduction S21 is performed, when a first device and a second device establish a bluetooth communication connection, the first device may broadcast a bluetooth signal through a first bluetooth module, when the second device enters a broadcast range of the first device, the first device may send a bluetooth connection request to the second device through the first bluetooth module, after receiving the bluetooth connection request sent by the first device, the second device may return response information to the first device through the second bluetooth module, and after receiving the response information indicating that the second device agrees to connect, the first device establishes a bluetooth communication connection with the second device.
The above is an implementation of S21, and the following describes an implementation of S22.
In an embodiment of the application, the ultra-wideband protocol information of the second device is information that can be used to determine an ultra-wideband communication protocol supported by the second device. Because the UWB protocol supported by each UWB device is usually set at the time of factory shipment, the UWB protocol supported by the UWB device can be determined according to the device identification information or the ultra-wideband protocol version information of the UWB device. Thus, the ultra-wideband protocol information may include device identification information or ultra-wideband protocol version information, etc.
In one example, if the uwb protocol information is the device identification information, the second device may send its own device identification information to the first device through the second bluetooth module after the bluetooth communication connection is established, so that the first device may perform device identification on the second device based on the device identification information of the second device. Based on this, after the first device establishes bluetooth communication connection with the second device, the second device can send the device identification information of itself to the first device through the second bluetooth module, so, the first device can acquire the device identification information of the second device, that is, the ultra wideband protocol information.
In another example, after the first device establishes a bluetooth communication connection with the second device, the first device may also send a protocol negotiation request to the second device through the first bluetooth module, where the protocol negotiation request is used to instruct the second device to send its ultra-wideband protocol information to the first device, and after receiving the protocol negotiation request, the second device sends its ultra-wideband protocol information to the first device through the second bluetooth module, so that the first device may acquire the ultra-wideband protocol information of the second device.
The above is an implementation of S22, and an implementation of S23 is described below.
A plurality of ultra-wideband communication protocols with different versions are preset in the first device.
In an example, if the ultra-wideband protocol information is device identification information, the first device may further preset a correspondence between the ultra-wideband protocol version information and the device identification information. Based on this, after the device identification information of the second device is acquired, the pre-stored correspondence may be searched for target ultra-wideband protocol version information corresponding to the device identification information of the second device, then the target ultra-wideband protocol version information is respectively matched with the preset version information of each ultra-wideband communication protocol, and finally the ultra-wideband communication protocol of which the version information is matched with the target ultra-wideband protocol version information is determined as the target ultra-wideband communication protocol supported by the second device.
In another example, if the ultra-wideband protocol information is ultra-wideband protocol version information, the received ultra-wideband protocol version information may be directly matched with version information of each preset ultra-wideband communication protocol, and the ultra-wideband communication protocol whose version information matches with the target ultra-wideband protocol version information is determined as a target ultra-wideband communication protocol supported by the second device.
By the implementation mode, the first device can determine the ultra-wideband communication protocol supported by the second device based on the Bluetooth communication with the second device, the user does not need to manually select the ultra-wideband communication protocol supported by the second device, and the efficiency is higher.
The above is an implementation of S23, and an implementation of S24 is described below.
In the first device, different ultra-wideband communication protocols correspond to different protocol stacks, after a target ultra-wideband communication protocol supported by the second device is determined, a target protocol stack corresponding to the target ultra-wideband communication protocol can be determined, and then ultra-wideband communication connection is established with the second device based on the target protocol stack.
The above is an implementation of S24.
The existing data communication method usually needs to manually turn on or turn off the ultra-wideband communication function of the UWB equipment, and the mode often has the problem of untimely turning on or turning off. Because the power consumption is higher when the ultra wide band communication function is in operation, therefore for UWB equipment such as cell-phones through battery power supply, if the ultra wide band communication function keeps the on state for a long time, can seriously influence the time of endurance of equipment.
Based on this, as another implementation manner of the present application, in order to reduce the device power consumption, the first device may control the ultra-wideband communication function of the second device to be turned on or off.
Specifically, as shown in fig. 3, before S24, the following steps may be further included:
s31, the first device sends a first Bluetooth control instruction to the second device, and the first Bluetooth control instruction is used for indicating the second device to start an ultra-wideband communication function.
The first device may generate a first bluetooth control instruction and send the first bluetooth control instruction to the second device through the first bluetooth module when it is determined that the preset ultra-wideband communication condition is satisfied. Wherein, the ultra wide band communication condition can be set according to actual demand.
In one example, the ultra-wideband communication condition may be receipt of a first instruction, wherein the first instruction is indicative of determining a first distance of a second device relative to a first device. Based on this, the first device may detect whether the first instruction is received when determining whether the preset ultra-wideband communication condition is satisfied, and determine that the ultra-wideband communication condition is satisfied when determining that the first instruction is received. The first instruction may be triggered by the first device itself, or may be sent by an external device, which is not limited to this. In this way, the power consumption of the second device may be further reduced.
And S32, the second equipment starts the ultra-wideband communication function based on the first Bluetooth control instruction.
In one example, an ultra-wideband switch for controlling the ultra-wideband communication function on and off may be provided in the second device. Based on this, the second equipment can control the ultra wide band switch to open after receiving first bluetooth control command through second bluetooth module to open ultra wide band communication function.
Further, after S24, the following steps may be further included:
and S33, the first equipment sends a second Bluetooth control instruction to the second equipment, wherein the second Bluetooth control instruction is used for indicating the second equipment to close the ultra-wideband communication function.
The first device may generate a second bluetooth control instruction and send the second bluetooth control instruction to the second device through the first bluetooth module when it is determined that the preset communication end condition is satisfied. Wherein, the communication end condition can be set according to the actual situation.
In one example, the end-of-communication condition may include obtaining a first distance of the second device relative to the first device. Based on this, the first device may detect whether the first distance is obtained or not in real time, and when it is determined that the first distance is obtained, it is determined that the communication end condition is satisfied.
In another example, the communication ending condition may include that a continuous time period during which no ultra-wideband communication is performed between the first device and the second device reaches a preset time period threshold, wherein the time period threshold may be set according to actual conditions. Based on this, after the first device establishes the ultra-wideband communication connection with the second device, the first device may determine, in real time, a continuous duration for which the ultra-wideband communication is not performed with the second device, compare the determined continuous duration with a duration threshold, and determine that a communication end condition is satisfied when the comparison shows that the continuous duration is greater than the duration threshold.
And S34, the second equipment closes the ultra-wideband communication function based on the second Bluetooth control instruction.
The second device can control the ultra-wideband switch to be closed after receiving the second Bluetooth control instruction through the second Bluetooth module, so that the ultra-wideband communication function is closed.
Through this kind of implementation, can be by opening or closing of ultra wide band communication function in the first equipment control second equipment, compare in artificial control, this kind of mode is more convenient and timely, can effectually avoid the waste of consumption.
As another implementation manner of the present application, after S24, the method may further include:
the first device determines a first distance of the second device relative to the first device by ultra-wideband communication with the second device.
In one example, when determining the first distance of the second device relative to the first device, the second device may send its location information to the first device through the second ultra-wideband module based on an ultra-wideband communication connection with the first device, and after receiving the location information of the second device through the first ultra-wideband module, the first device may calculate the first distance of the second device relative to the first device according to the location information of the second device and its location information.
In another example, the first device may employ a two-way time-of-flight (TW-TOF) method to determine a first distance of the second device relative to the first device. In particular, the first device may be at T based on an ultra-wideband communication connection established between the first device and the second device a1 Transmitting a pulse signal of a requested nature to a second device at a time T through a first ultra-wideband module b1 The pulse signal of the requested property is received by the second ultra-wideband module at the moment and is in T b2 A signal with response property is transmitted to the first device through the second ultra-wide band module at any time, and the first ultra-wide band module of the first device is at T a2 A signal of the nature of the response is received at a time. Therefore, the flight time of the pulse signal between the first device and the second device can be calculated, and the flight distance S can be further determined.
Specifically, the flight distance S can be calculated by the following formula:
S＝C×[(T a2 -T a1 )-(T b2 -T b1 )]
where C represents the speed of light.
The flying distance S is a first distance between the first device and the second device.
By this implementation, a first distance of the second device relative to the first device may be determined.
As another implementation manner of the present application, after determining the first distance of the second device relative to the first device, the method may further include:
the first device determines whether the second device meets a preset service processing condition according to the first distance, and sends a third Bluetooth control instruction containing service data to the second device when the second device meets the service processing condition, wherein the third Bluetooth control instruction is used for instructing the second device to perform service processing based on the service data.
And the second equipment performs service processing based on the service data according to the third Bluetooth control instruction.
The service processing conditions and the service data can be determined according to the actual service scene. For example, the data communication method provided by the embodiment of the application may be applied to an ultra-wideband payment scenario, in which the service data may include payment information, where the payment information may include information such as a merchant name, an account number, a payment amount, and a commodity name.
In one example, in an ultra-wideband payment scenario, the traffic handling condition may be that the second device is a UWB device closest to the first device. Based on this, when the first device determines whether the second device meets the preset service processing condition according to the first distance, the first distance may be compared with other distances, and if the first distance is smaller than all other distances, it is determined that the second device meets the service processing condition, where the other distances refer to distances between other UWB devices around the first device and the first device.
In another example, in an ultra-wideband payment scenario, the traffic handling condition may be that a distance between the second device and the first device is less than a preset distance threshold. Based on this, when the first device determines whether the second device meets the preset service processing condition according to the first distance, the first distance may be compared with a preset distance threshold, and when the first distance is smaller than the distance threshold, it is determined that the second device meets the service processing condition, where the distance threshold may be set according to an actual situation.
And after the first device determines that the second device meets the service processing condition, generating a third Bluetooth control instruction containing service data, and sending the third Bluetooth control instruction to the second device through the first Bluetooth module. After the second device receives the third bluetooth control instruction through the second bluetooth module, the third bluetooth control instruction may be analyzed to obtain the service data therein, then software corresponding to the service data is opened, and service processing is performed based on the service data by using the opened software. For example, in an ultra-wideband payment scenario, the second device may open the payment software and use the payment software to make payment based on the service data.
For convenience of understanding, the data communication method provided in the embodiment of the present application is described below by taking an application to an ultra-wideband payment scenario as an example.
Referring to fig. 4, which is an architecture diagram of a data communication system in an ultra-wideband payment scenario, as shown in fig. 4, the system includes a POS terminal as a first device and a mobile phone terminal as a second device. The POS terminal comprises a first data transmission unit, a first UWB protocol adaptation unit, a first UWB control unit and a first UWB protocol stack, and the mobile phone end comprises a second data transmission unit, a second UWB protocol adaptation unit, a second UWB control unit and a second UWB protocol stack. The first data transmission unit and the second data transmission unit, the first UWB protocol adaptation unit and the second UWB protocol adaptation unit, the first UWB control unit and the second UWB control unit adopt Bluetooth communication, and the first UWB protocol stack and the second UWB protocol stack adopt UWB communication.
Before the POS terminal and the mobile phone end establish UWB communication connection, protocol negotiation is carried out firstly, when the protocol negotiation is carried out, the first UWB protocol adaptation unit and the second UWB protocol adaptation unit establish Bluetooth connection, based on the Bluetooth connection, the mobile phone end returns the equipment identification information of the mobile phone to the POS terminal, and the POS terminal selects the UWB communication protocol version corresponding to the mobile phone according to the received equipment identification information.
After determining the UWB communication protocol version corresponding to the mobile phone, the first UWB control unit sends a first Bluetooth control instruction to the second UWB control unit, controls the second UWB control unit at the mobile phone end, and starts the UWB switch at the mobile phone end.
