The terms "one embodiment" and "an embodiment" mean "at least one embodiment". The term "another embodiment" means "at least one other embodiment".

Unless the context clearly indicates otherwise, the definition of a term is consistent throughout the specification.

[0021] like Figure 1 As shown, an embodiment of the present invention provides a voice interaction method for a slurry recovery device of a concrete mixing station, comprising: Step S101, after detecting a voice command, pre-process the voice command, identify the voiceprint feature corresponding to the pre-processed voice command, and determine whether the voice command comes from a bound user based on the voiceprint feature.

[0022] Specifically, during the operation of the slurry recovery equipment of the concrete mixing station, the voice command is detected by the voice acquisition sensor, and the collected voice command is preprocessed, including noise suppression, gain control and other steps to improve the quality of the obtained voice signal. Then, the voiceprint feature of the preprocessed voice signal is extracted, and the extracted voiceprint feature is used to determine whether the voice command comes from a bound user. For example, the extracted voiceprint feature is compared with the pre-stored voiceprint templates of all staff members, and the voice command is determined based on the comparison result. Whether it comes from a bound user, so as to decide whether to continue to execute the subsequent steps.

[0023] In addition, the preprocessing of voice commands may include noise suppression, such as filtering and spectral subtraction of voice commands to reduce the noise of the slurry recovery equipment in the background. The voice commands may also be gain controlled and signal enhanced to maintain a certain clarity of the human voice in the voice commands and obtain processed human voice. However, for human voice, because the human voice of the staff is not necessarily standard voice (Mandarin), but may be various dialects, it is necessary to identify the dialect corresponding to the human voice, and determine the corresponding dialect recognition model based on the dialect, wherein the dialect recognition module is a model that has been trained with sufficient dialect data sets and can correctly recognize the characteristics of the pronunciation of various dialects. The human voice is recognized by the dialect recognition model and converted into standard voice commands.

[0024] Step S102, when the voice command comes from a bound user, semantically parse the voice command, extract the keywords after the semantic analysis, and generate corresponding control codes through the keywords, wherein the control codes include: address code, function code, data code, and check code.

[0025] Specifically, when it is detected that the preprocessed voice instruction comes from a bound user, the voice instruction is semantically parsed, wherein the step of semantic parsing may include decomposing the voice text corresponding to the voice instruction into vocabulary units, decomposing the sentence structure, determining the subject, predicate and other components, and then comparing the vocabulary recognition result with the preset vocabulary database. Among them, the commonly used voice instructions in the slurry recovery equipment process of the concrete mixing station may include "add water to the parking space", "one-key material washing", "current fault", "parking space car washing", "high water level in the mixing tank", etc., then the predefined vocabulary database may include 3 types of databases, including an equipment vocabulary database, such as "slurry recovery pump", "mixing tank", etc., an action vocabulary database, such as "start", "stop", "accelerate", etc., and a numerical vocabulary database, such as "water level is set to 50%", "recovery speed is adjusted to 10 liters per minute", etc. Through the comparison results, the keywords after semantic parsing are determined, and the keywords may include corresponding equipment keywords, action keywords, and numerical keywords.

[0026] After determining the keywords, the corresponding control code can be generated according to the keywords of the voice command, where the control code includes address code, function code, data code, and check code. Taking the MODBUS communication protocol as an example, the generation steps and structure of the address code, function code, data code, and check code in the control code are shown as follows: Address code: Determine the slave device pointed to by the voice command according to the device keyword, that is, the target PLC or target touch screen, and generate the corresponding address code based on the encoding rules of the target PLC or target touch screen. The address code is located at the beginning of the control code. It is used to identify the address of the slave device to be accessed. In the network of the concrete mixing plant, each slave device has a unique address to distinguish different devices. In the MODBUS protocol, the address of the slave device usually starts from 1 and can be set to a maximum of 247 (0 is usually used as a broadcast address, indicating all slave devices). When the master device sends the address code, the address of the target slave device is included in the address code. After receiving the message, the slave device will check whether the address in the address field matches its own address, and respond accordingly if it matches.

[0027] Function code: Get the preset function coding rules, combine the action keywords, and generate the corresponding function code. For example, the function code 0x02 indicates the start of the slurry recovery program. The function code is located after the address field and is used to indicate the type of operation that the slave device needs to perform. The MODBUS protocol can define a series of function codes, each of which corresponds to a specific operation. The function code is usually one byte (8 bits) in length, and its value range varies depending on the different versions and extensions of MODBUS. In the standard MODBUS protocol, the function code range is usually 0x01 to 0xFF, but not all values ​​are defined and used. The function code tells the slave device what operation needs to be performed, such as reading a holding register, writing a single register, reading input status, etc. After receiving the function code, the slave device will perform the corresponding operation according to the code and return the result to the master device.

[0028] Data code: Based on the numerical keyword, combined with the preset numerical length and numerical format, the corresponding data code is generated. The data code is located after the function code and is used to contain the data or parameters required to perform a specific operation. The specific content and format of the data depends on the type of function code and the implementation of the slave device. The data code can contain information such as the register address to be read or written, the value to be written, and the amount of data to be read. Its length and format vary depending on the function code. The data field provides the slave device with specific information required to perform the operation. For example, the time and mode of slurry recovery.

[0029] Check code: Based on the address code, function code, data code, and preset check code calculation rules, the corresponding check code is calculated. The check code is located after the data code and is used to detect whether an error occurs during the transmission of the message. The sending device calculates the check code before sending the message and attaches it to the end of the message frame. After receiving the message, the receiving device recalculates the check code and compares it with the received check code to verify the integrity of the message. The function of the check code is to ensure that the message has not been tampered with or damaged during transmission. If the received check code does not match the recalculated check code, it indicates that an error occurred during the transmission of the message, and the receiving device can take appropriate error handling measures accordingly.

[0030] Step S103, establishing a communication connection with the communication address according to the communication address corresponding to the address code, and sending the control code to the target PLC or target touch screen.

[0031] Specifically, after determining the control code corresponding to the voice command, determine the communication protocol corresponding to the control code, such as Modbus RTU / ASCII / TCP, EtherCAT, ProfiNET, etc., and establish a connection with the slave device of the communication address corresponding to the address code, wherein the slave device can be a PLC or a target touch screen, and encapsulate the control code into a frame or message through the communication protocol, and send it to the target PLC or target touch screen. After the PLC reads the control code from the communication interface, it checks the check code in the control code to verify the data integrity. If the control code indicates to start the slurry recovery program, the PLC will control the valve to open, start the pumping system, and adjust the agitator speed. After the operation is completed, the PLC will feedback the operation results to the main control device. After receiving the control code, the target touch screen may need to display relevant information or operation prompts, and then the control code can be further forwarded to the PLC for processing according to the operation.

[0032] In addition, after receiving the feedback result of the target PLC or the target touch screen, when the check code error occurs in the feedback result, further detect whether there is an error in the address code, function code, and data code. When there is no error in the address code, function code, and data code, the check code generation rule can be changed to regenerate the check code. When there is an error in the address code, function code, and data code, the address code, function code, and data code are tried to be repaired in combination with the historical operation record. When the attempted repair fails, the voice command is re-collected. The process of the attempted repair can be, for example, when there is an error in the address code, the historical operation record is obtained, and the slave device to be operated in the next step is determined according to the operation steps of the previous step or the previous steps in the historical operation record. The wrong address code is attempted to be repaired through the address code of the slave device, and it is determined whether the attempted repair result meets the current operation requirements. The attempted repair method can also be, for example, based on the current operation time and the historical operation time. Empirical comparison is performed to determine the attempted repair plan. When the attempted repair fails, the voice command needs to be re-collected and the voice command is re-judged.

[0033] The embodiment of the present invention provides a voice interaction method for a slurry recovery device of a concrete mixing station. After detecting a voice command, the voice command is preprocessed, and the voiceprint feature corresponding to the preprocessed voice command is identified. Based on the voiceprint feature, it is determined whether the voice command comes from a bound user; when the voice command comes from a bound user, the voice command is semantically parsed, and the keywords after the semantic parsing are extracted. The corresponding control code is generated through the keywords, and the control code includes: address code, function code, data code, and check code; according to the communication address corresponding to the address code, a communication connection is established with the communication address, and the control code is sent to the target PLC or target touch screen. In this way, voice control of complex equipment operations can be realized, which reduces the difficulty of operators and improves the accuracy of operations.
