[0074] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0075] It should be noted that: in other embodiments, the steps of the corresponding method are not necessarily performed in the order shown and described in this specification. In some other embodiments, the steps included in the method may be more or less than those described in this specification. In addition, a single step described in this specification may be decomposed into multiple steps for description in other embodiments; and multiple steps described in this specification may be combined into a single step for description in other embodiments.

[0076] Currently, the master and slave devices have extremely strict requirements on the clock deviation and timing control of the single bus. Any time deviation at the microsecond level may cause the sending and receiving of bits between the communicating parties to be out of sync, which in turn leads to errors in data transmission.

[0077] Furthermore, for master and slave devices without an operating system, when the processor performance is high, microsecond-level timing control can be barely achieved. However, for master and slave devices with an operating system, even if the processor performance is very high, the multi-tasking and multi-process management characteristics of the operating system make it extremely difficult to achieve microsecond-level timing control. Even if it can be achieved, this process requires a huge cost, which violates the original design intention of using a single bus for communication, which is simple, easy to use, and low-cost.

[0078] Based on this, this specification proposes a technical solution for pulse encoding the target transmission data according to the target encoding and decoding mode, generating pulse data, and transmitting the pulse data between the master device and the slave device. Thus, the strict requirements on clock deviation and timing control in the single bus technology are avoided, the stability and rate of data transmission are improved, and the limitations caused by the insufficient processing capabilities of the master device and the slave device are reduced.

[0079] The technical solutions provided by the embodiments of this specification are described in detail below in conjunction with the accompanying drawings.

[0080] Figure 1 This is a flow chart of a data transmission method shown in an exemplary embodiment, and the method specifically includes the following steps:

[0081] S100: Obtain target transmission data and target encoding and decoding mode.

[0082] S102: Perform pulse coding on the target transmission data according to the target coding and decoding mode to generate pulse data corresponding to the target transmission data.

[0083] S104: Send the pulse data to the slave device, so that the slave device performs pulse decoding on the pulse data according to the target encoding and decoding mode to obtain the target transmission data.

[0084] In the embodiments of this specification, the data transmission method can be applied to a master device in a communication system, and the communication system includes: a master device and a slave device. Figure 2 shown.

[0085] Figure 2 It is a schematic diagram of a single bus communication system shown in an exemplary embodiment.

[0086] exist Figure 2 In the master device and the slave device, there are pulse generators, pulse counters, general purpose input / output (GPIO), etc. GPIO is a digital signal interface. A data line is used to establish a communication connection between the master device and the slave device.

[0087] Among them, the way to generate pulse data includes: edge-triggered level flipping of digital circuits (for example, from low level to high level or from high level to low level), pulse generator generating pulse data, etc. Pulse generators include: self-oscillation circuits, PWM signal generators, etc. Ways to count pulse data include: software counting, hardware counting. Software counting can refer to phase detection of pulses or I / O high and low levels, edge-triggered interrupts, etc. Hardware counting can refer to the use of special counter chips or circuits to achieve.

[0088] Furthermore, the pulse may be in the form of a square wave, a triangle wave, a sine wave, a sawtooth wave, or the like.

[0089] It should be noted that multiple data lines can be used to establish a communication connection between the master device and the slave device. Figure 3 shown.

[0090] Figure 3 FIG. 1 is a schematic diagram of a communication system with multiple data lines shown in an exemplary embodiment.

[0091] exist Figure 3 In the master device and the slave device, there are pulse generators, pulse counters, general input and output, etc. Multiple data lines can be used to establish a communication connection between the master device and the slave device.

[0092] In the embodiment of this specification, target transmission data and target encoding and decoding mode are obtained.

[0093] Then, according to the target coding and decoding mode, pulse coding is performed on the target transmission data to generate pulse data corresponding to the target transmission data.

[0094] Next, the pulse data is sent to the slave device, so that the slave device performs pulse decoding on the pulse data according to the target encoding and decoding mode to obtain the target transmission data.

[0095] In actual applications, it takes a while for the master device to pulse encode the target transmission data and for the slave device to pulse decode the pulse data. The length of the processing time is affected by the processing capabilities of the master and slave devices. Therefore, even when transmitting single-byte data, the fewer the number of pulses, the higher the communication performance. In fact, the communication performance is affected by many factors, including the number of pulse groups required to transmit single-byte data, the number of pulses in each group of pulses, the frequency of the pulses, and the processing capabilities of the master and slave devices. These factors together determine the efficiency and reliability of communication.

[0096] In the embodiment of this specification, the communication system stores at least one encoding and decoding mode.

[0097] Before obtaining the target transmission data and the target encoding and decoding mode, the device information of the master device and the device information of the slave device are obtained. The device information mentioned here may include: processor information, memory information, software configuration information, etc.

[0098] Then, based on the device information of the master device and the device information of the slave device, a target codec mode is selected from at least one codec mode.

[0099] It can be seen from the above embodiments that the communication system can select the encoding and decoding mode that best suits the current hardware configuration and communication requirements, thereby ensuring communication efficiency and data transmission reliability.

[0100] In the embodiment of this specification, the target coding mode includes: a first coding mode.

[0101] If the target coding mode is determined to be the first coding mode, pulse coding is performed on the value of the single-byte data in the target transmission data to obtain the number of pulses corresponding to the value of the single-byte data, wherein the single-byte data consists of eight bits.

[0102] Then, based on the number of pulses corresponding to the numerical value of the one-byte data, pulse data corresponding to the target transmission data is generated.

[0103] In the first encoding and decoding mode, only one set of pulses is needed to transmit a single-byte data. Since the value range of a single-byte data is 0 to 255, 1 to 255 pulses can be used to represent the values ​​1 to 255. Among them, the value 0 requires 256 pulses to be transmitted.

[0104] For example, when the value of the single-byte data is "0x01", the number of pulses is 1, and 1 pulse is transmitted. For another example, when the value of the single-byte data is "0x02", the number of pulses is 2, and 2 pulses are transmitted. Similarly, when the value of the single-byte data is "N", the number of pulses is N, and N pulses are transmitted.

[0105] It should be noted that when the value of the single-byte data is "0x00", the number of pulses is 256, and 256 pulses are transmitted.

[0106] Figure 4 It is a schematic diagram of a first encoding and decoding mode shown in an exemplary embodiment.

[0107] exist Figure 4In the example, the target transmission data is "0x01", "0x02", "0x03", "0x04", and "0x05". For example, a data line is used to establish a communication connection between the master device and the slave device. When the value of the single-byte data is "0x01", 1 pulse is transmitted. When the value of the single-byte data is "0x02", 2 pulses are transmitted. When the value of the single-byte data is "0x03", 3 pulses are transmitted. When the value of the single-byte data is "0x04", 4 pulses are transmitted. When the value of the single-byte data is "0x05", 5 pulses are transmitted.

[0108] In the embodiment of this specification, the target coding mode includes: a second coding mode.

[0109] If it is determined that the target encoding and decoding mode is the second encoding and decoding mode, the single-byte data in the target transmission data is divided to obtain two first sub-byte data, wherein the first sub-byte data consists of four bits.

[0110] Then, pulse encoding is performed on the value of the first sub-byte data to obtain the number of pulses corresponding to the value of the first sub-byte data.

[0111] Next, pulse data corresponding to the target transmission data is generated based on the number of pulses corresponding to the value of the first sub-byte data.

[0112] In the second encoding and decoding mode, the single-byte data is divided into two first sub-byte data, that is, two groups of pulses are required to transmit the single-byte data. Since the value range of the first sub-byte data is 0 to 15, 1 to 15 pulses can be used to represent the values ​​1 to 15 respectively. Among them, the value 0 requires 16 pulses to be transmitted.

[0113] For example, when the value of the single-byte data is "0x12", the first first sub-byte data is "1", the number of pulses of the first group of pulses is 1, and 1 pulse is transmitted. The second first sub-byte data is "2", the number of pulses of the second group of pulses is 2, and 2 pulses are transmitted. For another example, when the value of the single-byte data is "0x23", the first first sub-byte data is "2", the number of pulses of the first group of pulses is 2, and 2 pulses are transmitted. The second first sub-byte data is "3", the number of pulses of the second group of pulses is 3, and 3 pulses are transmitted. Similarly, when the value of the single-byte data is "0xNN", the first first sub-byte data is "N", the number of pulses of the first group of pulses is N, and N pulses are transmitted. The second first sub-byte data is "N", the number of pulses of the second group of pulses is N, and N pulses are transmitted.

[0114] It should be noted that when the value of the single-byte data is "0x00", the first sub-byte data is "0", the number of pulses in the first group of pulses is 16, and 16 pulses are transmitted. The second first sub-byte data is "0", the number of pulses in the second group of pulses is 16, and 16 pulses are transmitted.

[0115] Figure 5 It is a schematic diagram of a second encoding and decoding mode shown in an exemplary embodiment.

[0116] exist Figure 5 In the example, the target transmission data is "0x22", "0x33", and "0x44", and a data line is used to establish a communication connection between the master device and the slave device. When the value of the single-byte data is "0x22", the first first sub-byte data is "2", the number of pulses in the first group of pulses is 2, and 2 pulses are transmitted. The second first sub-byte data is "2", the number of pulses in the second group of pulses is 2, and 2 pulses are transmitted. When the value of the single-byte data is "0x33", the first first sub-byte data is "3", the number of pulses in the first group of pulses is 3, and 3 pulses are transmitted. The second first sub-byte data is "3", the number of pulses in the second group of pulses is 3, and 3 pulses are transmitted. When the value of the single-byte data is "0x44", the first first sub-byte data is "4", the number of pulses in the first group of pulses is 4, and 4 pulses are transmitted. The second first sub-byte data is "4", the number of pulses in the second group of pulses is 4, and 4 pulses are transmitted.

[0117] In the embodiment of this specification, the target coding mode includes: a third coding mode.

[0118] If it is determined that the target encoding and decoding mode is the third encoding and decoding mode, the single-byte data in the target transmission data is divided to obtain four second sub-byte data, wherein the second sub-byte data consists of two bits.

[0119] Then, pulse encoding is performed on the value of the second sub-byte data to obtain the number of pulses corresponding to the value of the second sub-byte data.

[0120] Next, pulse data corresponding to the target transmission data is generated based on the number of pulses corresponding to the value of the second subbyte data.

[0121] In the third encoding and decoding mode, the single-byte data is divided into four second sub-byte data, that is, four groups of pulses are required to transmit the single-byte data. Since the value range of the second sub-byte data is 0 to 3, 1 to 3 pulses can be used to represent the values ​​1 to 3 respectively. Among them, the value 0 requires 4 pulses to be transmitted.

[0122] Figure 6It is a schematic diagram of a third encoding and decoding mode shown in an exemplary embodiment.

[0123] exist Figure 6 In the example, the target transmission data is "0x5A" and "0xFF", and a data line is used to establish a communication connection between the master device and the slave device. When the value of the single-byte data is "0x5A", the binary is "01011010", the first second sub-byte data is "01", the number of pulses in the first group of pulses is 1, and 1 pulse is transmitted. The second second sub-byte data is "01", the number of pulses in the second group of pulses is 1, and 1 pulse is transmitted. The third second sub-byte data is "10", the number of pulses in the third group of pulses is 2, and 2 pulses are transmitted. The fourth second sub-byte data is "10", the number of pulses in the fourth group of pulses is 2, and 2 pulses are transmitted. When the value of the single-byte data is "0xFF", the binary is "11111111", the first second sub-byte data is "11", the number of pulses in the first group of pulses is 3, and 3 pulses are transmitted. The second second sub-byte data is "11", the number of pulses in the second group of pulses is 3, and 3 pulses are transmitted. The third second subbyte data is "11", the number of pulses in the third group of pulses is 3, and 3 pulses are transmitted. The fourth second subbyte data is "11", the number of pulses in the fourth group of pulses is 3, and 3 pulses are transmitted.

[0124] It should be noted that when the value of the single-byte data is "0x00", the binary is "00000000", the first second sub-byte data is "00", the number of pulses of the first group of pulses is 4, and 4 pulses are transmitted. The second second sub-byte data is "00", the number of pulses of the second group of pulses is 4, and 4 pulses are transmitted. The third second sub-byte data is "00", the number of pulses of the third group of pulses is 4, and 4 pulses are transmitted. The fourth second sub-byte data is "00", the number of pulses of the fourth group of pulses is 4, and 4 pulses are transmitted.

[0125] In the embodiment of this specification, the target coding mode includes: a fourth coding mode.

[0126] If the target encoding and decoding mode is determined to be the fourth encoding and decoding mode, the single-byte data in the target transmission data is divided to obtain eight third sub-byte data, wherein the third sub-byte data consists of one bit.

[0127] Then, pulse encoding is performed on the value of the third sub-byte data to obtain the number of pulses corresponding to the value of the third sub-byte data.

[0128] Next, based on the number of pulses corresponding to the value of the third subbyte data, pulse data corresponding to the target transmission data is generated.

[0129] In the fourth encoding and decoding mode, the single-byte data is divided into eight third sub-byte data, that is, eight groups of pulses are required to transmit the single-byte data. Since the value range of the third sub-byte data is 0 to 1, one pulse can be used to represent the value 1, and two pulses can be used to represent the value 0.

[0130] Figure 7 It is a schematic diagram of a fourth encoding and decoding mode shown in an exemplary embodiment.

[0131] exist Figure 7 In the example, a communication connection is established between a master device and a slave device using a data line. When the value of a single-byte data is "0xCC", the binary is "11001100", the first third sub-byte data is "1", the number of pulses in the first group of pulses is 1, and 1 pulse is transmitted. The second third sub-byte data is "1", the number of pulses in the second group of pulses is 1, and 1 pulse is transmitted. The third third sub-byte data is "0", the number of pulses in the third group of pulses is 2, and 2 pulses are transmitted. The fourth third sub-byte data is "0", the number of pulses in the fourth group of pulses is 2, and 2 pulses are transmitted. The fifth third sub-byte data is "1", the number of pulses in the fifth group of pulses is 1, and 1 pulse is transmitted. The sixth third sub-byte data is "1", the number of pulses in the sixth group of pulses is 1, and 1 pulse is transmitted. The seventh third sub-byte data is "0", the number of pulses in the seventh group of pulses is 2, and 2 pulses are transmitted. The eighth third sub-byte data is "0", the number of pulses in the eighth group of pulses is 2, and 2 pulses are transmitted.

[0132] It should be noted that when the value of the single-byte data is "0x00", the binary is "00000000", the first third sub-byte data is "0", the number of pulses of the first group of pulses is 2, and 2 pulses are transmitted. The second third sub-byte data is "0", the number of pulses of the second group of pulses is 2, and 2 pulses are transmitted. The third third sub-byte data is "0", the number of pulses of the third group of pulses is 2, and 2 pulses are transmitted. The fourth third sub-byte data is "0", the number of pulses of the fourth group of pulses is 2, and 2 pulses are transmitted. The fifth third sub-byte data is "0", the number of pulses of the fifth group of pulses is 2, and 2 pulses are transmitted. The sixth third sub-byte data is "0", the number of pulses of the sixth group of pulses is 2, and 2 pulses are transmitted.

The eighth third sub-byte data is "0", the number of pulses of the eighth group of pulses is 2, and 2 pulses are transmitted.

[0133] It can be seen from the above embodiments that, by using the target encoding and decoding mode among multiple encoding and decoding modes, the target transmission data is pulse-encoded, thereby avoiding the strict requirements on clock deviation and timing control in the single bus technology, improving the stability and rate of communication, and reducing the limitations caused by the insufficient processing capabilities of the master device and the slave device.

[0134] In the embodiments of this specification, a plurality of data lines may be used to establish a communication connection between the master device and the slave device, wherein different numbers of data lines correspond to different data transmission modes.

[0135] Then, based on the number of data lines and the target encoding and decoding mode, the target data transmission mode is determined.

[0136] Next, based on the target data transmission mode, the pulse data is sent to the slave device.
