[0002] Traditional embedded communication protocols, such as Modbus, are based on a master-slave architecture and are widely used to connect electronic devices for data exchange. Communication targets are divided into master and slave devices. The master device is generally the information acquirer and presenter, sending commands to the slave device based on the request. The slave device then performs actions based on the commands or provides information.

[0003] After a user issues an operation command through the master device, they must wait for the slave device to complete the action corresponding to the operation command and return the response data before sending the next command. The slave device takes a certain amount of time to execute the action corresponding to the operation command, which makes the current communication method inefficient. Summary of the Invention

[0046] Figure 1 This is a flowchart of an asynchronous communication method provided by the present invention. The present invention improves on the basis of existing embedded communication to realize asynchronous communication between the host and the slave. The method can be executed by the asynchronous communication system provided by the present invention. For example, Figure 1 As shown, the asynchronous communication method includes the following steps:

[0047] S101: The master device sends a command to the slave device.

[0048] In the embodiments of the present invention, a master device generally refers to a device that can actively send information. It possesses both initiative and control, initiating requests and controlling slave devices to complete tasks. The master device plays a dominant role in the communication process, initiating communication requests, managing the communication process, and actively controlling slave devices to perform corresponding tasks. A slave device, on the other hand, is a device that receives information and passively accepts requests from the master device and completes tasks accordingly. A slave device plays a subordinate role in the communication process, responding to requests from the master device and performing corresponding operations.

[0049] In an embodiment of the present invention, the master device sends an instruction to the slave device.

[0050] S102: The slave device parses the instruction sent by the master device to determine the instruction type.

[0051] After receiving the instruction, the slave device parses the instruction sent by the master device to determine the instruction type. In an embodiment of the present invention, the instruction type may include asynchronous instructions, synchronous instructions, and polling instructions. For example, the instruction may be a string of data including multiple data bits, one of which may be used as a data bit representing the instruction type, and different values of the data bit represent different instruction types. Among them, asynchronous instructions are used to control the slave device to perform corresponding actions, and synchronous instructions are used for the master device to obtain synchronization information from the slave device. The synchronization information is usually information with relatively low delay requirements. Polling instructions are used to periodically check whether a certain condition of the slave device is met or whether a certain data is ready. Polling instructions are used to obtain polling information with low delay requirements, such as execution result data of asynchronous instructions, operation logs of the slave device, error information of the slave device, etc. The present invention is not limited here.

[0052] In the embodiment of the present invention, the master device periodically sends polling instructions to the slave device according to a preset frequency.

[0053] S103: The slave device responds to the synchronization instruction in real time and returns the synchronization information cached in the register to the master device.

[0054] When the command type is a synchronous command, the slave device responds to the synchronous command in real time, returning the synchronization information cached in the register to the master device. This process is short, typically less than 100ms, and can be considered a real-time response. The synchronous command is primarily used by the master device to obtain information from the slave device.

[0055] S104: The slave device responds to the polling instruction and returns the polling information cached in the register to the master device.

[0056] When the command type is a polling command, the slave device responds to the polling command and returns the polling information cached in the register, the asynchronous command execution result data, the slave device's operation log, and the slave device's error information to the master device. It should be noted that if the data corresponding to the register is not yet ready, for example, if the action corresponding to the asynchronous command is still executing and the execution result data is not yet fully ready, the slave device will temporarily not respond to the polling command and wait for the next polling command. This process continues until the master device obtains the polling information.

[0057] S105 : The slave device responds to the asynchronous instruction and feeds back feedback information indicating whether the instruction is received successfully to the master device.

[0058] When the instruction type is an asynchronous instruction, the slave device responds to the asynchronous instruction and feeds back feedback information to the master device indicating whether the instruction was successfully received. Asynchronous instructions can be used to control the slave device to perform corresponding actions. For example, the instruction is provided with a data check bit, which verifies whether the instruction is correct. If correct, indicating successful instruction reception, the slave device feeds back feedback information indicating successful reception to the master device. If incorrect, indicating a problem occurred during instruction transmission, the slave device feeds back feedback information indicating failed instruction reception to the master device and does not respond to the instruction.

[0059] S106 , the slave device executes the action corresponding to the asynchronous instruction, and caches the execution result data generated during the execution of the action into a register of the slave device.

[0060] In an embodiment of the present invention, after successfully receiving the asynchronous instruction, the slave device executes the action corresponding to the asynchronous instruction, generates execution result data, and caches the execution result data in a register of the slave device.

[0061] S107 . While the slave device is executing the action corresponding to the asynchronous instruction, the master device sends a data acquisition instruction to the slave device.

[0062] While the slave device is executing an action corresponding to an asynchronous instruction, the master device can send a data acquisition instruction to the slave device. This data acquisition instruction can be a synchronization instruction or a polling instruction. In this way, while the master device is waiting for the slave device to execute an action, it can send a synchronization instruction or a polling instruction to the slave device to obtain synchronization information or a polling message indicating that it is ready. While the slave device is executing an action, it can send synchronization information or a polling message indicating that it is ready to execute to the master device. This achieves asynchronous communication between the master and slave devices and can improve communication efficiency.

[0063] In some embodiments of the present invention, the slave device parses a data acquisition instruction issued by the master device to determine the instruction type. If the instruction type is a synchronization instruction, the slave device responds to the synchronization instruction in real time and returns synchronization information cached in a register to the master device. If the instruction type is a polling instruction, the slave device returns action data cached in a register to the master device. The specific process has been described in detail in the aforementioned embodiments and will not be repeated here in the embodiments of the present invention.

[0064] The asynchronous communication method provided by the present invention comprises the following steps: a master device sends an asynchronous instruction to a slave device; the slave device responds to the asynchronous instruction and feeds back feedback information to the master device to indicate whether the instruction is received successfully; the slave device executes the action corresponding to the asynchronous instruction and caches the execution result data generated during the execution of the action into a register of the slave device; while the slave device is executing the action corresponding to the asynchronous instruction, the master device sends a data acquisition instruction to the slave device; in this way, while the master device is waiting for the slave device to execute the action, the master device can send a synchronization instruction or a polling instruction to the slave device to obtain synchronization information or polling information that is ready; while the slave device is executing the action, the master device can send synchronization information or polling information that is ready to be sent to the master device, thereby realizing asynchronous communication between the master device and the slave device and improving communication efficiency.

[0065] In the existing embedded communication method, if there is interference, if data interruption, garbled characters or other problems occur during data transmission, the communication status cannot be maintained, and repeated execution or data loss are prone to occur, and the communication stability is poor.

[0066] In some embodiments of the present invention, the instruction issued by the master device includes a serial number that represents the unique identity information of the instruction. After receiving the instruction, the slave device detects the instruction serial number, which may include asynchronous instructions, synchronous instructions, and polling instructions, and determines whether the serial number is a repeated serial number. If so, it indicates that the master device failed to obtain the corresponding data the previous time. In response to the instruction, the slave device returns the corresponding historical data cached in the register to the master device. In this way, there is no need to consider the timing between the various instructions. Even in the presence of interference, if data is interrupted or garbled during data transmission, it can be re-uploaded later, improving communication stability.

[0067] In some embodiments of the present invention, in order to reduce the accumulation of historical data in the register and release memory, the number of times an instruction is repeated can be counted based on the serial number to determine whether the number of times the instruction is repeated is greater than a preset number. If so, the historical data corresponding to the instruction is cleared from the register.

[0068] In some embodiments of the present invention, a master device is connected to multiple slave devices. While a slave device is executing an action corresponding to an asynchronous instruction, the master device sends instructions to other slave devices. The instructions may include asynchronous instructions, synchronous instructions, and polling instructions. In this way, asynchronous communication between the master device and different slave devices is achieved.

[0069] The present invention also provides an asynchronous communication system, which is used to execute the asynchronous communication method provided by any of the above embodiments. Figure 2 A schematic diagram of the structure of an asynchronous communication system provided by the present invention is shown in FIG. Figure 2 As shown, the asynchronous communication system includes a master device 110 and at least one slave device 120, and the master device 110 and the slave device 120 are connected, for example, Figure 2 Four slave devices 120 are taken as an example.

[0070] For example, in a specific embodiment of the present invention, the master device 110 is a mainboard of a coffee machine, and the slave devices include an extraction machine and a milk frother of the coffee machine.

[0071] Exemplarily, the main board sends an extraction instruction to the extraction machine. After receiving the instruction, the extraction machine parses the instruction and determines that the instruction type is an asynchronous instruction. After successfully receiving the asynchronous instruction, the extraction machine feeds back feedback information to the main board to indicate successful reception. At the same time, the extraction machine performs the extraction action, extracts the coffee liquid, generates extraction status data (whether the extraction is completed), and caches the extraction status data in the register of the slave device. During the process of the extraction machine extracting the coffee liquid, the main board can send a data acquisition instruction to the extraction machine. The data acquisition instruction can be a synchronous instruction or a polling instruction, which is used to obtain synchronous information or ready polling information, such as the currently set extraction temperature, duration, extraction status data and other data.
