Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

Referring to fig. 1, fig. 1 is a schematic diagram illustrating an embodiment of a conventional universal asynchronous receiver-based communication method.

The existing communication method based on the universal asynchronous transceivers is an asynchronous full duplex communication method, and each universal asynchronous transceiver comprises two interfaces, namely a Tx (Transmit end) and an Rx (Receive end). The transmitting end of the universal asynchronous receiver of the terminal equipment and the mobile terminal is connected with the receiving end of the opposite end, and the receiving end is connected with the transmitting end of the opposite end so as to communicate. In the existing method, the terminal equipment can directly send the prompt instruction to the mobile terminal and perform data query, and the mobile terminal can also directly perform prompt response and data reporting, so that the interaction between the control command and the service data for AT data transmission is very convenient. Wherein the transmission rate of the communication method based on the universal asynchronous receiver is based on the setting of the baud rate value, the baud rate value is expressed as bps (bit per second), for example, the bit rate value is set as 115200bps, and 115200 bits of data can be transmitted per second.

However, the transmission rate of the conventional universal asynchronous receiver depends on factors such as the clock frequency, the frequency division rate coefficient, the sampling time and the like of the universal asynchronous receiver, the maximum data transmission rate is generally between 230kbps and 460kbps, and the maximum data transmission rate cannot meet the requirement of the internet of things equipment on service data, for example, in the interaction of a certain smart home, the voice data amount of five seconds of which is usually about 1.5Mbps (1 mbps=1000 kbps) when the voice assistant turns on, if the transmission rate is 300kbps, the time of 5 seconds is required, and a certain time is required for processing the voice data, which obviously cannot meet the actual requirement on response time and response speed. Therefore, the communication method based on the universal asynchronous receiver/transmitter is not applicable in these application scenarios requiring high-speed data transmission.

Referring to fig. 2 and 3, fig. 2 is a schematic diagram of a terminal device sending data to a mobile terminal according to an embodiment of a conventional communication method based on a serial peripheral interface, and fig. 3 is a schematic diagram of a mobile terminal reporting data to a terminal device according to another embodiment of a conventional communication method based on a serial peripheral interface.

The existing communication method based on the Serial peripheral interfaces is a high-speed synchronous full duplex communication method, each Serial peripheral interface includes four pins of SCLK (Serial Clock line), MOSI (Master Output Slave Input, master input slave input line), MISO (Master Input Slave Output, master input slave output line), SS (SLAVE SELECT, slave select line), wherein the Serial Clock line is generated by the master and controls the communication speed, and is used for synchronizing data transmission between the master and the slave, the master output slave input line is used for transmitting data or instructions to the slave, the master input slave output line is used for transmitting data or status to the master, the slave select line is used for the master to select which slave to communicate with, and omission can be made in the communication process of the single terminal device and the single mobile terminal. The communication method based on the serial peripheral interface has the speed of 10Mbps to 20Mbps, and the data transmission rate of the communication method is far higher than that of the communication method based on the universal asynchronous receiver, so that the communication method can better adapt to the communication requirement of the Internet of things equipment.

The terminal equipment and the mobile terminal are based on the communication of the serial peripheral interface, wherein the terminal equipment is used as a host, and the mobile terminal is used as a slave. Communication methods based on serial peripheral interfaces provide that communication between two devices must be initiated by a master device, but when AT command data interaction is performed, a slave machine needs to report some data, and if the slave machine needs to report data to a host machine, a handshake signal needs to be added to inform the host machine to perform a read operation, and subsequent data transmission can be performed after handshake is completed.

Referring to fig. 2, when the communication method based on the serial peripheral interface is applied to a terminal device sending data to a mobile terminal, the terminal device needs to send a prompt instruction to the mobile terminal first, after receiving the prompt instruction, the mobile terminal needs to trigger GPIO (General Purpose Input-Output) interrupt if the data is allowed to be received, after responding to the interrupt, the interrupt device reads and detects the state of the mobile terminal for receiving the data again, and sends the data to the mobile terminal, and sends an end prompt to the mobile terminal after the data sending is finished, so as to inform the mobile terminal that the data sending is finished.

Referring to fig. 3, when the communication method based on the serial peripheral interface is applied to reporting data to the terminal device by the mobile terminal, the mobile terminal writes a flag bit to indicate that the terminal device is allowed to read and trigger the GPIO interrupt, the terminal device responds to the state that the terminal reads and detects the data receiving state of the mobile terminal, the terminal device initiates a data reading operation to receive the data, and after the receiving is finished, the terminal device sends an end prompt to the mobile terminal.

As can be seen from the embodiments of fig. 2 and fig. 3, when the control command of the AT and the service data are transmitted by using the serial peripheral interface, multiple interactions are required, the flow is complex, and the actual effective service data transmission efficiency is low. Especially, when the mobile terminal needs to report data to the terminal equipment, the data transmission cannot be actively initiated, and after a handshake signal is added to inform the terminal equipment to generate a terminal signal, the terminal equipment initiates a data reading operation, so that the software interaction process is complex.

Therefore, the existing communication methods described based on fig. 1 to 3 cannot simultaneously improve the data transmission efficiency and reduce the complexity of the interaction flow, and have certain limitations when applied to data interaction and transmission communication between the terminal device and the mobile terminal of the internet of things device.

Referring to fig. 4, fig. 4 is a schematic diagram of an embodiment of a communication method according to the present application, where the communication method includes:

Step 11: the first universal asynchronous receiver-transmitter of the terminal device sends a prompt instruction to the second universal asynchronous receiver-transmitter of the mobile terminal to inform the mobile terminal of receiving the first service data.

Step 12: in response to the first universal asynchronous receiver-transmitter receiving the first prompt reply sent by the second universal asynchronous receiver-transmitter, the first serial peripheral interface of the terminal equipment initiates a data writing operation to the second serial peripheral interface of the mobile terminal to write the first service data into the mobile terminal.

The first prompt response is used for representing that the second serial peripheral interface is in a state of receiving the first service data.

Step 13: in response to the first universal asynchronous receiver-transmitter receiving the second prompt reply sent by the second universal asynchronous receiver-transmitter, the first serial peripheral interface initiates a data read operation to the second serial peripheral interface to read the second service data from the mobile terminal.

The second prompt response is used for notifying the terminal equipment to receive second service data.

The steps 11 to 13 are steps of the communication method described in fig. 4, and are applied to interaction and data transmission between the terminal device side and the mobile terminal, wherein the first prompt response and the second prompt response are both received through the first universal asynchronous transceiver, the prompt instruction is sent out through the first universal asynchronous transceiver, the first service data is sent out through the first serial peripheral interface, and the second service data is received through the first serial peripheral interface. The prompting instruction, the first response instruction and the second response instruction are set according to AT control command rules interacted between the terminal equipment and the mobile terminal, so long as corresponding functions can be realized. For example, the prompting instruction may be an instruction such as "at+cusd" in the AT instruction set, for sending a request for receiving the first service data to the mobile terminal, the first prompting response may include a response instruction such as "OK" or "CONNECT" for notifying that the terminal device is ready to receive the first service data, and the second prompting response may include a response instruction such as "READ" or "RING" for notifying that the terminal device starts to READ the second service data.

In the communication method, the prompt instruction, the first response instruction and the second response instruction are transmitted through the universal asynchronous receiver-transmitter, so that the communication method can be directly transmitted to the opposite end without handshake, the data size of the interaction data is small, the interaction of the AT control command can be rapidly completed by using the universal asynchronous receiver-transmitter, the data interaction efficiency is improved, the complexity of the interaction process is reduced, and the complexity of corresponding software development is reduced. Meanwhile, in the communication method, the first serial peripheral interface initiates data writing operation and data reading operation to the second serial peripheral interface, and the data writing operation and the data reading operation are transmitted through the serial peripheral interface, and the serial peripheral interface is only used for transmitting corresponding service data in the process, so that a complex handshake flow in the existing method is omitted, the transmission efficiency is high, and the communication is reliable. In addition, in the method, the mobile terminal can have more initiative and can directly and actively initiate data response and data reporting without being limited by a master-slave mode of the serial peripheral interface, so that the mobile terminal can interact with the terminal equipment more flexibly, and the communication efficiency and reliability are improved. The communication method can simultaneously give consideration to the improvement of data transmission efficiency and the reduction of complexity of an interaction flow, can improve the efficiency and the reliability of data transmission when being applied to data interaction and transmission communication between terminal equipment and a mobile terminal of the Internet of things equipment, and can effectively improve the efficiency and the reliability of data transmission and reduce the complexity of the interaction flow by transmitting a prompt instruction, a first response instruction and a second response instruction through a universal asynchronous transceiver and initiating data writing operation and data reading operation to a second serial peripheral interface by a first serial peripheral interface.

Referring to fig. 5, fig. 5 is a flow chart of another embodiment of a communication method according to the present application, where the communication method includes:

Step 21: the second universal asynchronous receiver-transmitter of the mobile terminal receives the prompt instruction sent by the first universal asynchronous receiver-transmitter of the terminal equipment.

The prompting instruction is used for prompting the mobile terminal to receive the first service data.

Step 22: the second universal asynchronous receiver transmitter transmits a first prompt acknowledgement to the first universal asynchronous receiver transmitter.

Wherein the first prompt response is used for representing that the second serial peripheral interface of the mobile terminal is in a state of receiving the first service data

Step 23: the second serial peripheral interface receives a data writing operation initiated by the first serial peripheral interface of the terminal equipment so as to write first service data.

Step 24: the second universal asynchronous receiver-transmitter transmits a second prompt response to the first universal asynchronous receiver-transmitter to inform the terminal device of receiving the second service data.

Step 25: the second serial peripheral interface receives a data read operation initiated by the first serial peripheral interface to allow the first serial peripheral interface to read second traffic data from the second serial peripheral interface.

The steps 21 to 25 are steps of the communication method described in fig. 5, and are applied to interaction and data transmission between the mobile terminal side and the terminal device, where the first prompt response and the second prompt response are both sent by the second universal asynchronous transceiver, the prompt instruction is received by the second universal asynchronous transceiver, the first service data is received by the second serial peripheral interface, and the second service data is sent by the second serial peripheral interface. The specific process steps, embodiments and advantages of the method can be referred to the communication method described in fig. 4, and will not be described herein.

Referring to fig. 6, fig. 6 is a schematic structural diagram of an embodiment of a terminal device according to the present application.

The terminal device 30 comprises a memory 31 and a processor 32 connected to each other, the memory 31 storing a computer program, the processor 32 being connected to a first universal asynchronous receiver-transmitter 33 and to a first serial peripheral interface 34, the processor 32 implementing the steps of the communication method as described in fig. 4 when the computer program is executed.

Referring to fig. 7, fig. 7 is a schematic structural diagram of an embodiment of a mobile terminal according to the present application.

The mobile terminal 40 comprises a memory 41 and a processor 42 connected to each other, the memory 41 storing a computer program, the processor 42 being connected to a second universal asynchronous receiver-transmitter 43 and to a second serial peripheral interface 44, the processor 42 executing the computer program to perform the steps of the communication method as described in fig. 5.

Referring to fig. 8, fig. 8 is a schematic structural diagram of an embodiment of a communication system according to the present application.

The communication system 50 comprises a terminal device 30 comprising a first universal asynchronous receiver-transmitter 33 and a first serial peripheral interface 34, and a mobile terminal 40 comprising a second universal asynchronous receiver-transmitter 43 and a second serial peripheral interface 44, the first universal asynchronous receiver-transmitter 33 and the second universal asynchronous receiver-transmitter 43 being arranged to transmit interactive data, and the second serial peripheral interface 34 and the first serial peripheral interface 44 being arranged to transmit traffic data. The terminal device and the mobile terminal may be, besides the terminal device described in fig. 6 or the mobile terminal described in fig. 7, another terminal device or mobile terminal that is independently developed, so long as the terminal device and the mobile terminal have a corresponding universal asynchronous transceiver and a serial peripheral interface.

The interactive data, i.e. data required for interaction between the terminal device and the mobile terminal, is used for informing the opposite terminal, controlling the opposite terminal or receiving the opposite terminal information, for example, the interactive data may include the foregoing prompt instruction, the AT control command including the first prompt response and the second prompt response, and the corresponding response, and may also include, for example, signal strength of the terminal device or the mobile terminal, network coverage area, battery power, various status information of the current time, etc., and according to the status information, corresponding responsive or triggered control may be performed, where the interactive data generally has a relatively small information amount, so that effective and reliable data transmission may also be performed through the universal asynchronous receiver. The service data, that is, the aforementioned first service data written into the mobile terminal by the terminal device, or the second service data reported to the terminal device by the mobile terminal, may be in various forms, such as text information, image information, audio information, application programs, etc., and these service data are used for performing various service operations and information exchange, and generally have a relatively large information volume, so as to meet the time and speed requirements of the time communication of the internet of things device, the service data may be transmitted by a high-speed communication method based on a serial peripheral interface.

Because the terminal equipment and the mobile terminal used in the existing internet of things equipment are generally provided with the universal asynchronous receiver-transmitter and the serial peripheral interface, and have certain uniformity in terms of protocol, for example, the setting of the bit rate value of the universal asynchronous receiver-transmitter, the setting of the master-slave property of the serial peripheral interface and the like have similar standards, or the serial peripheral interface and the mobile terminal can be adjusted through an internal program or a parameter adjusting interface, so that the terminal equipment and the mobile terminal can coordinate to operate, and effective and reliable data transmission is performed. Therefore, the communication system has stronger compatibility and applicability, can be well applied to various Internet of things equipment, performs efficient interaction control and data transmission, and can effectively reduce the complexity of an interaction flow while improving the data transmission efficiency.

Optionally, the first universal asynchronous receiver-transmitter transmits a prompt instruction to the second universal asynchronous receiver-transmitter to inform the mobile terminal of receiving the first service data.

In the communication system, interactive control and data transmission are carried out between terminal equipment and a mobile terminal, wherein the system is embodied as two communication situations, one is that the terminal equipment writes first service data into the mobile terminal, and the other is that the mobile terminal reports second service data to the terminal equipment, and the two communication situations can be well realized in the system. The specific process steps, embodiments and advantages of the method may be referred to as the communication method described in fig. 4 or fig. 5, and will not be described herein.
