[0050] The present application provides a data communication method, which realizes a differentiated error processing mechanism by dynamically identifying and classifying I2C communication error patterns, including intelligent retransmission, hierarchical recovery strategy, and embeds state awareness and recovery logic in master and slave devices, thereby improving the stability of communication and the adaptability of the system.

[0051] Specifically refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 is a flowchart of the first embodiment of the data communication method provided by the present application, Figure 2 is a logic diagram of the data communication framework provided by the present application, Figure 3 is a schematic diagram of the overall flow of the data communication method provided by the present application.

[0052] To solve the problems of single error handling and lack of self-recovery capability in existing I2C communication, the present application introduces error pattern recognition mechanism, hierarchical processing mechanism and master-slave device self-recovery mechanism, the overall system composition, function and working process are as shown in Figure 2 , the following will be introduced by a specific data communication method:

[0053] As Figure 1 shown, the specific steps are as follows:

[0054] Step S11: Listen to the communication state on the integrated circuit bus between the master device and the slave device.

[0055] In the embodiments of the present application, as Figure 3 shown, the data communication device monitors and identifies error signals in the data communication process by listening to the communication state on the integrated circuit bus between the master device and the slave device, thereby ensuring the real-time performance of fault handling.

[0056] Specifically, the data communication device listens to the signals transmitted on the I2C communication bus between the master device and the slave device. In normal cases, the data signals on the I2C communication bus are generally periodic signals or signals with a preset response sequence. When the data communication device listens to signals on the I2C communication bus that deviate from the normal signal rules, it can be considered that the communication between the master device and the slave device is abnormal at this time.

[0057] Step S12: generating an error feature according to the abnormal signal when the communication state has the abnormal signal.

[0058] In the embodiments of the present application, as shown in the error mode recognition mechanism, Figure 2 the data communication device records the timing information and amplitude information of the abnormal signal occurrence process when it listens to the abnormal signal on the I2C communication bus, analyzes the abnormal features of the abnormal signal, that is, the error features.

[0059] The encoding mode of the error feature can compare the abnormal signal and the normal signal in terms of timing and amplitude, and encode the difference as a feature output.

[0060] In the embodiments of the present application, the data communication device can recognize the following common abnormal signals by real-time listening to the I2C communication process:

[0061] a) ACK abnormality: the master device does not receive the response of the slave device.

[0062] b) Data NACK: a non-response signal is received after data transmission.

[0063] c) START / STOP conflict: control bit conflict, such as accidental repeated start.

[0064] d) Other interference signals: such as bus suspension, abnormal level maintenance, etc.

[0065] Taking the ACK abnormal signal as an example, the data communication device should be able to record the receiving timing of the slave device response signal in the normal signal, but the master device has not received the slave device response signal all the time, so the data communication device can encode the absence of the receiving timing as the error feature of the ACK abnormal signal.

[0066] Step S13: matching the corresponding error mode in the error mode database using the error feature.

[0067] In the embodiments of the present application, the data communication device matches the error feature in the built-in error mode database and outputs the following contents:

[0068] a) Error type number (such as transient interference, timing conflict, slave failure, etc.).

[0069] b) Suggested action (such as retransmission, short delay wait, soft reset, inform master, etc.).

[0070] c) Error level (low, medium, high risk).

[0071] It should be noted that the functions of each module in the system structure shown in Figure 2 can be realized in a combination of software and hardware. For example, for the error pattern recognition mechanism, in hardware design, I2C can recognize error patterns (ACK exception, data NACK, START / STOP conflict, level holding exception, etc.) according to the protocol. For interference signals, the state of the corresponding IO can be monitored to identify error patterns.

[0072] Secondly, in the error classification logic design, the hardware can specify the risk level and the corresponding suggested action, and execute the corresponding suggested action through the corresponding state.

[0073] Step S14: According to the error pattern, a corresponding processing strategy is executed for the communication between the master device and the slave device.

[0074] In the embodiments of the present application, the data communication device executes a corresponding processing strategy for the communication failure between the master device and the slave device according to the error pattern determined in step S13.

[0075] Specifically, the processing strategy can be determined by the data communication device according to the error pattern, or can be determined by the suggested action pre-bound to the error pattern in the error pattern database, or can be determined by the error level pre-bound to the error pattern in the error pattern database.

[0076] It should be noted that when the data communication device matches the error pattern according to the error characteristics in step S13, it is possible to match multiple error patterns. At this time, the data communication device can determine the closest error pattern to determine the processing strategy according to the matching degree of the multiple error patterns, or can determine the processing strategy according to the corresponding suggested action or error level in the multiple error patterns. For example, when most of the multiple error patterns correspond to the error level of medium risk, the data communication device can determine the processing strategy according to the error level of medium risk.

[0077] Further, the processing strategies corresponding to different communication failures are respectively provided by Figure 2 the intelligent retransmission mechanism or the master-slave self-recovery mechanism shown in the figure, and the data communication device selects the corresponding mechanism to execute the processing strategy according to the specific communication failure.

[0078] Specifically, the intelligent retransmission mechanism and the master-slave self-recovery mechanism can be implemented by hardware or software, mainly depending on the size limit of the IP, the experience of the designer, etc. If implemented by software, the hardware needs to cooperate to complete the related configuration, state, etc. design, for example, the hardware should support 1) setting the delay time; 2) setting the retransmission number threshold; 3) triggering the state of the reset logic, and the software driver designs the corresponding control strategy according to these logic designs.

[0079] Based on Figure 1 The data communication method shown in the application also provides another data communication method, please refer to Figure 4 , Figure 4 is the flowchart of the second embodiment of the data communication method provided by the application.

[0080] As Figure 4 shown, the specific steps are as follows:

[0081] Step S21: determining a first intelligent retransmission strategy according to the error risk level of the error mode.

[0082] In the embodiments of the application, the error mode classification and processing behavior provided by the application includes but is not limited to:

[0083]

[0084] The data communication device determines the corresponding first intelligent retransmission strategy according to the error risk level of the matched error mode. As shown in the above table, when the matched error risk level is the low risk level, the data communication device determines the first intelligent retransmission strategy as immediate retransmission according to the recommended processing strategy corresponding to the low risk level.

[0085] Step S22: performing retransmission on the communication data between the master device and the slave device according to the first intelligent retransmission strategy.

[0086] In the embodiments of the application, the data communication device performs immediate retransmission on the communication data between the master device and the slave device according to the first intelligent retransmission strategy.

[0087] Step S23: determining a second intelligent retransmission strategy in response to the number of consecutive retransmission failures reaching a preset number during the process of performing retransmission on the communication data according to the first intelligent retransmission strategy.

[0088] In the embodiments of the application, the data communication device continuously monitors the communication state on the integrated circuit bus between the master device and the slave device after performing immediate retransmission. When abnormal signals still appear, it continues to perform immediate retransmission until the retransmission is successful, or the number of consecutive retransmissions reaches the preset number.

[0089] When the number of consecutive retransmission failures reaches the preset number and the retransmission is still unsuccessful, the data communication device determines a second intelligent retransmission strategy, wherein the first intelligent retransmission strategy corresponds to a lower error risk level than the second intelligent retransmission strategy.

[0090] As shown in the above table, the data communication device determines the second intelligent retransmission strategy as short-delay post-retransmission.

[0091] Step S24: Performing retransmission on the communication data between the master device and the slave device according to the second intelligent retransmission strategy.

[0092] In the embodiment of the present application, the data communication device performs short-delay post-retransmission on the communication data between the master device and the slave device according to the second intelligent retransmission strategy.

[0093] Further, when the retransmission strategy fails, it indicates that the data communication device cannot completely solve the problem according to the intelligent retransmission mechanism, and the data communication device can execute a corresponding processing strategy according to the master-slave self-recovery mechanism. Figure 2 As shown in the master-slave self-recovery mechanism, the corresponding processing strategy includes but is not limited to: master-slave device reset, master self-recovery, slave self-recovery, etc.

[0094] Based on the data communication method shown in Figure 4 , the present application further provides another data communication method, please refer to Figure 5 , Figure 5 is a flow diagram of the third embodiment of the data communication method provided by the present application.

[0095] As shown in Figure 5 , the specific steps are as follows:

[0096] Step S31: Determining the error subject according to the error type of the error mode, wherein the error subject is the master device or the slave device.

[0097] In the embodiment of the present application, when the data communication device selects the master-slave self-recovery mechanism to process the current communication failure, it can determine the error subject according to the error type of the error mode. As shown in the above table, when the error type is "retransmission failure", "master failure" or "master arbitration time-out", the data communication device determines that the error subject is "master". As shown in the above table, when the error type is "multi-slave failure", the data communication device determines that the error subject is "slave".

[0098] Step S32: Executing a self-recovery strategy on the error subject.

[0099] In the embodiment of the present application, the data communication device can execute the self-recovery strategy of the error subject according to the error subject determined in step S31.

[0100] Based on the data communication method shown in Figure 4The data communication method shown in the embodiment of the present application also provides another data communication method, please refer to Figure 6 , Figure 6 is a flowchart of the fourth embodiment of the data communication method provided by the present application.

[0101] As shown in Figure 6 , the specific steps are as follows:

[0102] Step S41: obtaining the error risk level and the recommended processing strategy of the error mode.

[0103] In the embodiment of the present application, there may be a case that the error risk level and the recommended processing strategy do not correspond one by one when the data communication device matches the error mode, for example, a case that multiple error modes are matched.

[0104] Step S42: determining the third intelligent retransmission strategy according to the recommended processing strategy.

[0105] Step S43: determining the first intelligent retransmission strategy according to the error risk level.

[0106] In the embodiment of the present application, the data communication device determines the corresponding intelligent retransmission strategy according to the recommended processing strategy and the error risk level respectively, and sorts the intelligent retransmission strategies according to the risk levels corresponding to the intelligent retransmission strategies.

[0107] Step S44: performing retransmission on the communication data between the master device and the slave device according to the third intelligent retransmission strategy.

[0108] In the embodiment of the present application, the data communication device preferentially performs retransmission on the communication data between the master device and the slave device according to the intelligent retransmission strategy with a lower risk level.

[0109] Step S45: performing retransmission on the communication data between the master device and the slave device according to the first intelligent retransmission strategy when the retransmission fails.

[0110] In the embodiment of the present application, the data communication device performs retransmission on the communication data between the master device and the slave device according to the intelligent retransmission strategy with a higher risk level when the intelligent retransmission strategy with a lower risk level cannot solve the current communication failure.

[0111] It should be noted that, Figure 6 The data communication method shown in the embodiment of the present application shows the retransmission logic of the intelligent retransmission mechanism, and relative to Figure 2 The master-slave self-recovery mechanism also has a self-recovery logic. For example, the data communication device can preferentially execute the slave self-recovery strategy, and then execute the master self-recovery strategy, the master-slave self-recovery strategy when the communication failure cannot be solved.

[0112] Further, when the reset is not effective for multiple times or the self-recovery is not effective for multiple times, the data communication device can consider closing the corresponding master / slave or other ways, reducing the risk of system downtime.

[0113] The data communication method provided by the application greatly improves the communication success rate and system stability, shortens the retransmission response time, and reduces the risk of system downtime through the error mode identification mechanism, the differentiated error processing strategy, and the master / slave device self-recovery mechanism.

[0114] Those skilled in the art can understand that, in the above method of the specific embodiment, the writing order of each step does not mean a strict execution order and does not constitute any limitation on the implementation process, and the specific execution order of each step should be determined according to its function and possible internal logic.
