[0002] With the continuous improvement of people's living standards and the continuous improvement of the intelligent level of household appliances, intelligent household appliances are becoming more and more popular. Users can use an air conditioner for heating in winter to increase the indoor temperature; they can also use an air conditioner for cooling in summer to lower the indoor temperature.

[0003] In the related art, for the monitoring and debugging of the operating state of the motor used in an air conditioner, it can be achieved through a host computer. At the same time, in order to meet the real-time requirement for the feedback of multiple parameters of the motor operating state, a relatively high communication rate is required.

[0004] However, under different actual application requirements of the motor drive chip, in order to minimize costs while meeting the working requirements, chips with relatively low clock and communication rate capabilities are often selected in some established drive schemes, resulting in an inability to match the communication rate between the drive chip and the host computer, thereby affecting the monitoring and debugging of the motor operating state.

Specific embodiments

[0035] To make the objectives, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below with reference to the accompanying drawings in this application. Obviously, the described embodiments are some but not all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without making creative efforts shall fall within the scope of protection of this application.

[0036] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the associated objects before and after.

[0037] The following gives a detailed description of the professional terms involved in the embodiments of this application: Host computer: A host computer refers to a computer that can directly issue control commands, usually a PC, a host computer or an upper computer. It runs high-level application programs, is responsible for processing and managing data, interacting with users, and communicating with lower-level computers. The lower-level computer directly controls the device and obtains the device status, usually a PLC or a single-chip microcomputer, etc. In an automated control system, the host computer communicates with the lower-level computer through various communication protocols (such as RS232, RS485, Ethernet, etc.) to obtain the operating status of the lower-level computer and send control commands.

[0038] Baud rate: It refers to the number of changes in the signal waveform transmitted per unit time, that is, the number of symbols transmitted in a unit time. In the field of electronic communication, the baud rate is the modulation rate, which represents the rate at which the effective data signal modulates the carrier wave, that is, the number of times the carrier modulation state changes per unit time. The baud rate can be understood as the number of symbol elements transmitted per unit time (symbol transmission rate). Through different modulation methods, multiple bit information can be carried on one symbol element. For example, if each symbol represents one bit of information, then the baud rate is equal to the number of data bits transmitted per unit time. However, if the data is compressed, then the number of data bits transmitted per unit time is usually greater than the modulation rate, resulting in an error between baud and bits / second.

[0039] To solve the above technical problems in the related art, an embodiment of the present application provides a motor debugging system, as Figure 1 shown. The motor debugging system includes: a host computer, a data buffer board, and a motor drive board. To ensure the timeliness of the feedback motor parameters and the stability of data transmission, the motor debugging system provided in the embodiment of the present application uses an intermediate data buffer board as a data communication transfer device between the host computer and the motor drive board. In the actual application process, the communication rates between the host computer, the data buffer board, and the motor drive board need to be kept consistent.

[0040] The following combines the accompanying drawings to describe in detail the communication rate coordination method of the motor debugging system provided in the embodiment of the present application through specific embodiments and their application scenarios.

[0041] As Figure 2 shown, a communication rate coordination method of a motor debugging system applied to a host computer provided in an embodiment of the present application may include the following steps 201 to step 203: Step 201, when the handshake communication with the data buffer board is completed based on the first baud rate, send a first control instruction to the data buffer board.

[0042] Wherein, the first control instruction is used to control the data buffer board to obtain the communication rate supported by the motor drive board based on the communication rate list.

[0043] Exemplarily, before monitoring and debugging the operating state of the motor, the host computer first needs to establish a communication connection with the data buffer board. Then, control the data buffer board to obtain the communication rate supported by the click drive board through the first control instruction.

[0044] Specifically, the step of sending the first control instruction to the data buffer board in the above step 201 may further include the following step 201a: Step 201a: Loop through and send the first control instruction to the data buffer board based on the communication rate list until the first response information sent by the data buffer board is received; Among them, the communication rate list includes multiple communication rates and the priority of each communication rate; the host computer sends the first control instruction to the data buffer board in descending order of the priority of each communication rate in the multiple communication rates; the communication rate carried each time the first control instruction is sent is different.

[0045] Exemplarily, the host computer can loop through and send the first control instruction to the data buffer board in descending order of the priority of each communication rate in the communication rate list. The communication rate carried in each first control instruction is different, and the priority of the communication rate carried in each sent first control instruction is not higher than the priority of the communication rate carried in the previous first control instruction.

[0046] Exemplarily, the purpose of the first control instruction is to control the data buffer board to send a corresponding control instruction to the motor drive board based on the communication rate carried in the first control instruction after receiving the first control instruction. If the current communication rate is consistent with the communication rate supported by the motor drive board, the motor drive board can normally receive and parse the control instruction and feedback a correct response. At this time, the data buffer board can determine that the current communication rate is the communication rate supported by the motor drive board and report it to the host computer through the first response information.

[0047] It should be noted that in the embodiments of the present application, through the program burned on the data buffer board, the host computer can send a corresponding control instruction to the data buffer board to control the data buffer board to perform a specific task.

[0048] Step 202: In the case of receiving the first response information sent by the data buffer board, send a second control instruction to the data buffer board based on the second baud rate indicated by the first response information.

[0049] Among them, the second control instruction is used to control the data buffer board to send an information acquisition instruction to the motor drive board at the second baud rate and receive the motor operation information sent by the motor drive board at the second baud rate.

[0050] Exemplarily, after the host computer receives the first response information sent by the data buffer board, it can send a second control instruction to the data buffer board based on the second baud rate indicated by the first response information. After receiving the second control instruction, the data buffer board can send an information acquisition instruction to the motor drive board at the second baud rate and receive the motor operation information sent by the motor drive board at the second baud rate.

[0051] Exemplarily, after receiving the motor operation information sent by the motor drive board, the data cache board can forward the motor operation information to the host computer.

[0052] Step 203: Receive the motor operation information sent by the motor drive board forwarded by the data cache board based on the second baud rate.

[0053] Exemplarily, after receiving the motor operation information sent by the data cache board, the host computer can monitor and debug the motor operation state based on the motor operation information.

[0054] In this way, when the motor drive board is connected to the motor debugging system, the communication rate negotiation among the host computer, the data cache board, and the motor drive board can be automatically realized, and the motor operation information can be obtained in real time without human participation.

[0055] Optionally, in the embodiment of the present application, handshake communication can be completed with the data cache board at a pre-negotiated communication rate.

[0056] Exemplarily, before the above step 201, the communication rate coordination method of the motor debugging system provided by the embodiment of the present application may further include the following step 204: Step 204: Send a handshake command to the data cache board at the first baud rate, and complete the handshake communication with the data cache board when receiving the response message sent by the data cache board in response to the handshake command.

[0057] Exemplarily, the host computer can send a handshake command (for example, command [F0 00 00]) to the data cache board at a pre-set communication rate (i.e., the above first baud rate, for example, the baud rate is 921600), and complete the handshake communication with the data cache board after receiving the response message (for example, command [40 00 00]) sent by the data cache board.

[0058] Optionally, in the embodiment of the present application, the success rate of each communication rate can be counted according to the communication rate when the data cache board successfully establishes a communication connection with the motor drive board, and the priority of each communication rate can be determined based on the success rate of each communication rate.

[0059] Exemplarily, after the above step 202, the communication rate coordination method of the motor debugging system provided by the embodiment of the present application may further include the following step 205: Step 205: Count the success rate corresponding to each communication rate in the communication rate list during the process of obtaining the communication rates supported by the motor drive board this time, and update the priority of each communication rate in the communication rate list based on the success rate corresponding to each communication rate.

[0060] Among them, the priority of the communication rate is positively correlated with the success rate of the communication rate.

[0061] Exemplarily, after adjusting the priorities corresponding to the respective communication rates in the communication rate list, when subsequently obtaining the communication rates supported by the motor drive board, attempts can be made in descending order of priority.

[0062] It should be noted that in each statistical operation, except for the communication rates supported by the motor drive board being marked as successful, other communication rates are marked as failed.

[0063] The communication rate coordination method for the motor debugging system provided by the embodiments of the present application, in the case of completing the handshake communication with the data buffer board based on the first baud rate, sends a first control instruction to the data buffer board; the first control instruction is used to control the data buffer board to obtain the communication rates supported by the motor drive board based on the communication rate list; in the case of receiving the first response information sent by the data buffer board, based on the second baud rate indicated by the first response information, sends a second control instruction to the data buffer board; the second control instruction is used to control the data buffer board to send an information acquisition instruction to the motor drive board at the second baud rate and receive the motor operation information sent by the motor drive board based on the second baud rate; receives the motor operation information sent by the motor drive board and forwarded by the data buffer board based on the second baud rate. In this way, the coordination of the communication rates among the host computer, the data buffer board, and the drive chip can be achieved, and the rate negotiation between the host computer and the drive chip and the acquisition of the operation state information can be automatically completed.

[0064] As Figure 3 shown, the embodiments of the present application also provide a communication rate coordination method for the motor debugging system applied to the data buffer board, and this method may include the following steps 301 to 304: Step 301, receive the first control instruction sent by the host computer, and in response to the first control instruction, obtain the second baud rate supported by the motor drive board based on the communication rate list.

[0065] Among them, the first control instruction is: the host computer sends it in the case of completing the handshake communication with the data buffer board based on the first baud rate.

[0066] In a possible implementation manner, in the above step 301, the step of obtaining the second baud rate supported by the motor drive board may include the following steps 301a1 and 301a2: Step 301a1: In response to the first control instruction, based on the priorities of the communication rates in the communication rate list from high to low, sequentially send a second control instruction to the motor drive board at different communication rates until the second response information sent by the motor drive board is received.

[0067] Wherein, the communication rate list includes multiple communication rates and the priority of each communication rate.

[0068] Step 301a2: Determine the communication rate when the second response information sent by the motor drive board is received as the second baud rate, and send the first response information to the host computer.

[0069] Wherein, the first response information carries the second baud rate; the priorities of the communication rates in the communication rate list are determined based on the success rate corresponding to the communication rates during communication between the data buffer board and the motor drive board.

[0070] Exemplarily, after receiving the first control instruction from the host computer, communication with the motor drive board can be attempted sequentially according to the priorities of the communication rates in the communication rate list until a communication connection is established, then determine the communication rate supported by the motor drive board, and feedback this communication rate to the host computer.

[0071] In another possible implementation, in the above step 301, the step of obtaining the second baud rate supported by the motor drive board may include the following step 301b: Step 301b: In response to the first control instruction, send a second control instruction to the motor drive board based on the communication rate carried in the first control instruction, and when the second response information sent by the motor drive board is received, send the first response information to the host computer.

[0072] Wherein, the communication rate carried in the first control instruction is a communication rate in the communication rate list, and the priority of the communication rate carried in the first control instruction is negatively correlated with the number of times the first control instruction is received; the first response information carries the second baud rate; the second baud rate is the communication rate when the motor drive board sends the second response information.

[0073] Exemplarily, since the host computer carries the communication rate that needs to be attempted currently in the first control instruction, after the data buffer board receives the first control instruction sent by the host computer, it can attempt to communicate with the motor drive board based on the communication rate carried in the first control instruction. If successful, it will feedback the communication rate supported by the click drive board to the host computer; otherwise, it will feedback a failure result and wait for and execute the first control instruction sent by the host computer next time.

[0074] Step 302: When obtaining the second baud rate supported by the motor drive board, send a first response message to the host computer; the first response message carries the second baud rate.

[0075] Step 303: When receiving the second control instruction sent by the host computer based on the second baud rate, in response to the second control instruction, send an information acquisition instruction to the motor drive board.

[0076] Step 304: When receiving the motor operation information sent by the motor drive board based on the second baud rate, send the motor operation information to the host computer based on the second baud rate.

[0077] In this way, the data buffer board can cooperate with the host computer to complete the acquisition of the communication rate supported by the motor drive board, and realize the real-time acquisition of the motor operation information based on the acquired communication rate.

[0078] Optionally, in the embodiments of the present application, the handshake communication with the host computer can be completed through the following steps.

[0079] Exemplarily, before the above step 301, the communication rate coordination method of the motor debugging system provided by the embodiments of the present application may further include the following step 305: Step 305: Receive the handshake instruction sent by the host computer based on the first baud rate, and in response to the handshake instruction, send a response message to the host computer.

[0080] Wherein, the response message is used to complete the handshake communication with the host computer.
