Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The following describes an information transmission control method, a terminal, a data acquisition device, and an information transmission control system according to an embodiment of the present invention with reference to the drawings.

Fig. 1 is a flowchart of a transmission control method of information according to an embodiment of the present invention. It should be noted that the information transmission control method according to the embodiment of the present invention can be described from the terminal side.

As shown in fig. 1, the information transmission control method may include:

s101, receiving a starting instruction input by a Bluetooth module in the terminal.

In the embodiment of the present invention, the terminal may include, but is not limited to, a mobile phone, a tablet computer, a personal digital assistant, and other hardware devices with various operating systems.

Specifically, a user can start a bluetooth function in the terminal device in a manual mode, a voice mode and the like on the terminal device, and when a start instruction input by the user is detected, a bluetooth module in the terminal can be started.

S102, N Bluetooth data packet transmission protocol types supported by the terminal are obtained, and N data packet identity information is generated according to the N Bluetooth data packet transmission protocol types, wherein N is a positive integer.

In the embodiment of the present invention, the bluetooth packet transmission protocol type may include, but is not limited to, an SPP protocol type, a BLE protocol type, an OPP protocol type, and the like.

It can be understood that the bluetooth module in each terminal stores one or more bluetooth packet protocols, and the terminal performs bluetooth communication with the external device through the stored protocol. Therefore, when the terminal starts the bluetooth module, the terminal can acquire the bluetooth packet transfer protocol type supported (or stored) by the terminal itself, and generate corresponding packet identity information according to the bluetooth packet transfer protocol type, where the packet identity information may include the identity of the corresponding bluetooth packet transfer protocol, and may also include information such as the size of a packet to be transferred. That is, the bluetooth packet transmission protocol represented by the identity can be found according to the identity, for example, the identity is OPP, the corresponding protocol is OPP, the identity is SPP, the corresponding protocol is SPP, the identity is BLE, and the corresponding protocol is BLE.

S103, a Bluetooth pairing request is sent to the periphery of the terminal, wherein the Bluetooth pairing request comprises N data packet identity information, so that data collectors around the terminal receive the Bluetooth pairing request and select a target Bluetooth communication protocol type according to the N data packet identity information.

It can be understood that the bluetooth packet transfer protocol in the bluetooth protocol system is divided into four layers according to the attention degree of the SIG specification: 1) core protocol: BaseBand, LMP, L2CAP, SDP; 2) cable replacement protocol: RFCOMM; 3) telephony delivery control protocol: TCS-Binary, AT command set; 4) selecting a protocol: PPP, UDP/TCP/IP, OBEX, WAP, vCard, vCal, IrMC, WAE. In addition to the protocol layers described above, the SIG specification defines a Host Controller Interface (HCI) that may provide a command interface for the baseband controller, connection manager, hardware status, and control registers. Wherein HCI can be located at the lower layer of L2CAP, and HCI can also be located at the upper layer of L2 CAP. The bluetooth core protocol consists of a bluetooth specific protocol established by the SIG. Most bluetooth devices require a core protocol (plus a wireless portion), while other protocols are dependent on the needs of the application. In summary, the cable replacement protocol, the telephony control protocol and the adopted protocol constitute an application-oriented protocol on the basis of the core protocol.

In the embodiment of the present invention, a bluetooth pairing request may be sent to the periphery of the terminal through an SDP protocol in any one of bluetooth transport protocols supported by the terminal, where the request carries the packet identity information. The data acquisition unit can scan through an SDP protocol when starting a Bluetooth module of the data acquisition unit, and can select an optimal Bluetooth communication protocol type as a target Bluetooth communication protocol type according to data packet identity information in a request when receiving a Bluetooth pairing request sent by the terminal.

In the embodiment of the present invention, the target bluetooth communication protocol type is selected by the data collector according to the priority levels corresponding to the multiple bluetooth packet transfer protocols and the identity information of the N packets, where the priority levels corresponding to the multiple bluetooth packet transfer protocols are determined by the data collector in advance according to the performance of the multiple bluetooth packet transfer protocol types.

That is to say, the data collector may select a bluetooth packet transfer protocol with the highest performance from a plurality of bluetooth packet transfer protocols pre-stored by the data collector according to the packet identity information corresponding to the bluetooth communication protocol type supported by the terminal, and use the bluetooth packet transfer protocol as a target bluetooth communication protocol.

And S104, receiving the target Bluetooth communication protocol type sent by the data acquisition unit, and carrying out data communication with the data acquisition unit according to the target Bluetooth communication protocol type.

Specifically, the terminal may receive a target bluetooth communication protocol type fed back by the data collector through an SDP protocol in the bluetooth transport protocol, and may perform data communication with the data collector according to the target bluetooth communication protocol type when the terminal and a user of the data collector confirm bluetooth pairing. That is, the terminal may first send its own packet identity information to the data collector via the SDP protocol in any (or the most basic) bluetooth transport protocol supported by the terminal, and the data collector selects a target bluetooth communication protocol type according to the packet identity information and provides the target bluetooth communication protocol type to the terminal. And after receiving the target Bluetooth communication protocol type, the terminal can carry out data communication with the data acquisition unit according to the target Bluetooth communication protocol type. In the embodiment of the present invention, the data collector may be a terminal, such as a mobile phone, a tablet computer, and the like, so as to realize a function of transmitting data such as files, images, and the like between two different terminals; the data acquisition unit can also be data acquisition equipment with real-time data acquisition and processing functions, and the data acquisition unit can be communicated with the terminal through a Bluetooth communication protocol so as to acquire data such as files, sensors and the like in the terminal through Bluetooth communication.

In the embodiment of the invention, the file transmission mode can be entered through a logical link control and adaptation protocol (L2CAP), a call Service Discovery Protocol (SDP) and a cable replacement protocol (RFCOMM) in a target Bluetooth communication protocol, so that files in various formats can be transmitted between a terminal and a data collector.

According to the information transmission control method of the embodiment of the invention, an opening instruction input by a user for a Bluetooth module in a terminal is received, N data packet identity information is generated according to N acquired Bluetooth data packet transmission protocol types supported by the terminal, a Bluetooth pairing request carrying the N data packet identity information is sent to the periphery of the terminal, a data acquisition unit can select a target Bluetooth communication protocol type according to the N data packet identity information and send the target Bluetooth communication protocol type to the terminal when receiving the request, the terminal performs data communication with the data acquisition unit according to the received target Bluetooth communication protocol type sent by the data acquisition unit, namely, a plurality of Bluetooth communication protocols are prestored in the data acquisition unit, an optimal Bluetooth communication protocol is selected from the plurality of Bluetooth communication protocols in the data acquisition unit by acquiring the Bluetooth communication protocol type supported by the terminal, and according to the best Bluetooth communication protocol, the Bluetooth data communication between the two devices is realized, the transmission rate and the success rate of data packets are improved, different external Bluetooth devices can be in compatible communication, and the use convenience of users is improved.

Further, in an embodiment of the present invention, in the process of performing data communication with the data collector according to the target bluetooth communication protocol type, the information transmission control method further includes: judging whether an operation instruction for initializing the data acquisition unit by a user is received; and if the operation instruction is received, initializing the data acquisition unit and synchronizing the position and time of the terminal and the setting information of the sensor. The terminal can acquire the position information of the terminal through a GPS positioning system of the terminal, and can acquire the time information of the terminal through a timer of the terminal. Further, the sensor may be, but is not limited to, a temperature sensor, a light-sensitive sensor, and the like.

That is, in the process of performing data communication with the data collector according to the type of the target bluetooth communication protocol, that is, in the process of waiting for a transmission instruction of a user, it is determined whether an operation instruction for initializing the data collector by the user is received, and if so, the data collector is initialized, and information such as setting information (such as setting parameters) of a position, time, a temperature sensor, a light-sensitive sensor, and the like in the terminal is synchronized to the data collector.

In order to make the present invention more clearly understood by those skilled in the art, the following may illustrate the implementation process of the information transmission control method according to the embodiment of the present invention. Fig. 2 is a flowchart of a method for controlling information transmission according to an embodiment of the present invention.

For example, as shown in fig. 2, a user may start a bluetooth function of a terminal device such as a mobile phone, a tablet computer, etc. to prepare a bluetooth pairing data collector (S201). After the bluetooth module of the terminal is turned on, the bluetooth packet transfer protocol types supported by the terminal itself may be acquired (S202), and corresponding packet identity information, such as identity ID ═ OPP, identity ID ═ SPP, identity ID ═ BLE, and the like, may be generated according to these types, and a bluetooth pairing request carrying the packet identity information is sent to the surroundings through any one of the bluetooth packet transfer protocols supported by the data collector itself, and when receiving the request, the data collector may select an optimal bluetooth communication protocol type according to the packet identity information (S203). Waiting for user pairing confirmation or a transfer instruction (S204). When the pairing is successful and an operation instruction for initializing the data collector is received (S205), the data collector may be initialized and parameter information of the terminal, such as a position, time, and a sensor, may be synchronized (S206). Thereafter, the packet transfer per frame through the target bluetooth communication protocol type (i.e., the optimal bluetooth communication protocol type) may be started according to the information transfer instruction (S207). Whether the frame data is successfully transmitted is detected (S208), if so, whether a data packet is successfully transmitted is detected (S209), and if so, the method returns to the step S204 with a new transmission instruction. It is understood that if there is frame loss data, the process returns to step S207, and if there is a frame loss data packet, the process returns to step S208.

That is, the data collector can switch the bluetooth communication protocol packet according to different data packet identity information. If the identity ID is OPP, bluetooth data communication can be carried out with the terminal through the OPP protocol, and if the identity ID is SPP, bluetooth data communication can be carried out with the terminal through the SPP protocol, and if the identity ID is BLE, bluetooth data communication can be carried out with the terminal through the BLE protocol.

Therefore, the information transmission control method of the embodiment of the invention can scan the Bluetooth module in the terminal by a rapid data packet protocol, and selects the best protocol transmission mode by receiving the protocol scanning result of the terminal and analyzing the data size through the data acquisition unit, so that the terminal and the data acquisition unit realize the Bluetooth data communication through lower power consumption, and the use experience of a user is improved.

Corresponding to the information transmission control methods provided in the foregoing embodiments, an embodiment of the present invention further provides a terminal, and since the terminal provided in the embodiment of the present invention corresponds to the information transmission control methods provided in the foregoing embodiments, embodiments of the information transmission control methods described above are also applicable to the terminal provided in this embodiment, and are not described in detail in this embodiment. Fig. 3 is a schematic structural diagram of a terminal according to an embodiment of the present invention. As shown in fig. 3, the terminal may include: a receiving module 110, a generating module 120, a transmitting module 130 and a data communication module 140.

Specifically, the receiving module 110 may be configured to receive an opening instruction input for a bluetooth module in the terminal.

The generating module 120 may be configured to obtain N bluetooth packet transfer protocol types supported by the terminal, and generate N data packet identity information according to the N bluetooth packet transfer protocol types, where N is a positive integer. In the embodiment of the present invention, the bluetooth packet transmission protocol type may include, but is not limited to, an SPP protocol type, a BLE protocol type, an OPP protocol type, and the like.

The sending module 130 may be configured to send a bluetooth pairing request to the periphery of the terminal, where the bluetooth pairing request includes N data packet identity information, so that the data collector receives the bluetooth pairing request and selects a target bluetooth communication protocol type according to the N data packet identity information.

The data communication module 140 may be configured to receive a target bluetooth communication protocol type sent by the data collector, and perform data communication with the data collector according to the target bluetooth communication protocol type.

Further, in an embodiment of the present invention, as shown in fig. 4, the terminal may further include a determining module 150 and an initializing module 160.

Specifically, the determining module 150 may be configured to determine whether an operation instruction for initializing the data collector is received in a process that the data communication module 140 performs data communication with the data collector according to the target bluetooth communication protocol type. The initialization module 160 may be configured to initialize the data collector and synchronize the position and time of the terminal and the setting information of the sensor when the determination module 150 determines that the operation instruction is received.

In order to implement the above embodiments, the present invention further provides another information transmission control method.

Fig. 5 is a flowchart of a transmission control method of information according to still another embodiment of the present invention. It should be noted that the information transmission control method according to the embodiment of the present invention may be described from a data acquisition side.

As shown in fig. 5, the information transmission control method may include:

s501, receiving a starting instruction input by a Bluetooth module in the data acquisition unit.

For example, the bluetooth function in the data collector can be started by the user through manual or voice on the data collector, and when the start instruction input by the user is detected, the bluetooth module of the data collector can be started.

S502, a Bluetooth pairing request is sent to the periphery of the data acquisition unit, wherein the Bluetooth pairing request comprises an acquisition request of a Bluetooth data packet transmission protocol type, so that the terminals around the data acquisition unit acquire N Bluetooth data packet transmission protocol types supported by the terminals according to the acquisition request, and generate N data packet identity information according to the N Bluetooth data packet transmission protocol types, wherein N is a positive integer.

Specifically, a bluetooth pairing request may be sent to the surroundings through an SDP protocol in any one of the bluetooth packet transfer protocols in the data collector, where the request includes an acquisition request of the type of the bluetooth packet transfer protocol. When the terminal scans and receives the Bluetooth pairing request, all Bluetooth data packet transmission protocol types supported by the terminal can be acquired according to the acquisition request, and corresponding data packet identity information is generated according to the Bluetooth data packet transmission protocol types, wherein the data packet identity information can contain the identity of the corresponding Bluetooth data packet transmission protocol and can also contain information such as the size of a data packet to be transmitted. That is, the bluetooth packet transmission protocol represented by the identity can be found according to the identity, for example, the identity ID ═ OPP, the corresponding protocol is OPP protocol, the identity ID ═ SPP, the corresponding protocol is SPP protocol, the identity ID ═ BLE, and the corresponding protocol is BLE protocol.

In the embodiment of the present invention, after the terminal generates the packet identity information, the terminal may feed back the packet identity information to the data collector through a bluetooth packet transmission protocol of the terminal itself (the protocol may be the most common and basic protocol, and the protocol may be corresponding to the protocol used when the data collector previously sent the pairing request).

S503, receiving the N data packet identity information sent by the terminal, and selecting the target Bluetooth communication protocol type according to the N data packet identity information.

Preferably, in an embodiment of the present invention, the priority levels corresponding to a plurality of bluetooth packet transmission protocols may be determined in advance according to the performance of the bluetooth packet transmission protocol types stored in advance in the data collector, where a high-performance protocol corresponds to a higher priority level, and a low-performance protocol corresponds to a lower priority level. The performance may refer to a data transfer rate, a minimum power consumption, and the like

Specifically, in the embodiment of the present invention, after receiving the packet identity information sent by the terminal, the bluetooth packet transfer protocol type with the highest priority level among the N bluetooth packet transfer protocol types may be obtained according to the priority levels corresponding to the multiple bluetooth packet transfer protocols and the N packet identity information, and the bluetooth packet transfer protocol type with the highest priority level may be selected as the target bluetooth communication protocol type.

And S504, performing data communication with the terminal according to the type of the target Bluetooth communication protocol.

Specifically, after the target bluetooth communication protocol type is selected, the bluetooth protocol in the data collector may be switched to the target bluetooth communication protocol, that is, the data collector may switch the bluetooth communication protocol packet according to the identity information of different data packets, and when the terminal and the user of the data collector confirm bluetooth pairing, may establish bluetooth connection with the terminal according to the target bluetooth communication protocol type, and perform data communication. For example, if the identity ID is OPP, bluetooth data communication may be performed with the terminal through the OPP protocol, and if the identity ID is SPP, bluetooth data communication may be performed with the terminal through the SPP protocol, and if the identity ID is BLE, bluetooth data communication may be performed with the terminal through the BLE protocol.

Further, in an embodiment of the present invention, in the process of performing data communication with the data collector according to the target bluetooth communication protocol type, the information transmission control method may further include: judging whether an operation instruction for initializing the data acquisition unit is received; and if the operation instruction is received, initializing the data acquisition unit and synchronizing the position and time of the terminal and the setting information of the sensor. The terminal can acquire the position information of the terminal through a GPS positioning system of the terminal, and can acquire the time information of the terminal through a timer of the terminal. Further, the sensor may be, but is not limited to, a temperature sensor, a light-sensitive sensor, and the like.

That is, in the process of performing data communication with the data collector according to the type of the target bluetooth communication protocol, that is, in the process of waiting for a transmission instruction of a user, the data collector may determine whether an operation instruction for initializing the data collector by the user is received, if so, initialize the data collector, and synchronize information such as setting information (such as setting parameters) of a position, time, a temperature sensor, a light-sensitive sensor, and the like in the terminal to the data collector. It is understood that, in the embodiment of the present invention, the data collector may also be automatically initialized and enter the standby state after the data packet is completely transferred.

Optionally, in an embodiment of the present invention, in the process of performing data communication with the data collector according to the target bluetooth communication protocol type, the information transmission control method may further include: acquiring identification information of a terminal; and establishing a corresponding relation between the identification information of the terminal and the data packet identity information corresponding to the target Bluetooth communication protocol type, and storing the corresponding relation. That is, the data collector can store the data packet identity information of the successfully paired devices, so that the pairing time can be saved when the device is started next time.

In order to make the skilled person in the art understand the present embodiment more clearly, the following may illustrate the implementation process of the information transmission control method of the present embodiment.

For example, as shown in fig. 6, a user may start a bluetooth function of a data collector to prepare for being searched for pairing by a terminal such as a mobile phone, a tablet computer, etc. (S601). The data acquisition device acquires a protocol type which can be used for a Bluetooth transmission data packet protocol in the terminal (S602), wherein the terminal can generate corresponding data packet identity information according to the Bluetooth transmission data packet protocol type supported by the terminal and sends the data packet identity information to the data acquisition device, so that the data acquisition device can acquire the protocol type which can be used for the Bluetooth transmission data packet protocol in the terminal according to the data packet identity information. Then, a target bluetooth communication protocol type may be selected according to the packet identity information, and the target bluetooth communication protocol type is enabled for bluetooth communication, for example, when the identity ID is OPP, the target bluetooth communication protocol type is OPP, when the identity ID is SPP, the target bluetooth communication protocol type is SPP, and when the identity ID is BLE, the target bluetooth communication protocol type is BLE (S603). The data collector can also switch the Bluetooth communication protocol packet according to different data packet identities. Waiting for user pairing confirmation or a transfer instruction (S604). When the pairing is successful and an operation instruction for initializing the data collector is received (S605), the data collector may be initialized and parameter information of the terminal, such as a position, time, and a sensor, may be synchronized (S606). Thereafter, the packet transfer per frame through the target bluetooth communication protocol type (i.e., the optimal bluetooth communication protocol type) may be started according to the information transfer instruction (S607).
