[0047] Specifically, the engineering equipment self-checking and state query system is applied to large hoisting equipment, which comprises a main control module and a programmable controller, the voice recognition unit is in communication connection with the control unit, and is used to transmit the received voice password to the control unit; in the preferred embodiment of the present application, bus communication is usually used for information transmission, the main control module and the programmable controller are connected by a communication circuit, and in another preferred embodiment of the present application, the main control module and the programmable controller can be connected by RS-485 communication. Figure 2 As shown in the drawings, the main control module and the programmable controller can communicate by RS-485 communication mode. The RS-485 communication circuit can be composed of a SP3485 chip and its peripheral circuit, and is connected with the main control module to convert the data protocol code of the main control chip into RS485 signal and send it to the programmable controller, and also receives the data protocol code sent by the programmable controller.

[0048] The main control module is used to receive and recognize the voice password from the operator through the voice recognition unit, and send the recognition result corresponding to the voice password to the programmable controller, wherein the voice password comprises a self-checking password and a query password.

[0049] Specifically, the voice password of the operator is received and recognized, wherein the voice password comprises a self-check password or an inquiry password, for example, the operator shouts the voice password to the microphone on the master module, and the voice recognition unit receives and recognizes the voice password from the microphone. In the preferred embodiment of the application, the voice password can be sent to the control unit in the form of a code, for example, "0x01" is sent to the control unit as a code, which facilitates the control unit to analyze the code of the voice password to obtain the recognition result. In the preferred embodiment of the application, the voice password also comprises a wake-up password. The control unit analyzes the received voice password to obtain the corresponding recognition result. In the preferred embodiment of the application, when the control unit receives the code, the recognition result obtained by analyzing the code is a string of data protocol codes, and the recognition result can be obtained by analyzing each control frame bit of the data protocol code, wherein the first bit of the data protocol code represents that the control unit sends data to the programmable controller, the second bit "01" is the instruction type, which can represent the "self-check" or "inquiry" instruction, the third bit is the sensor type code, the fourth and fifth bits are data bits, the sixth bit is the check code, and the seventh bit is the frame tail, which represents the end of the data protocol code.

[0050] The programmable controller is configured to acquire data of the parameter detection device according to the recognition result and send the data to the master module.

[0051] Specifically, when the programmable controller receives the recognition result, the data of the corresponding parameter detection device is acquired according to the recognition result, and the data of the parameter detection device is returned to the master module, so as to realize the data communication between the programmable controller and the master module.

[0052] The master module is further configured to receive the data and process the data, and broadcast and display the processed data.

[0053] Specifically, when the master module receives the data of the parameter detection device returned by the programmable controller, the data comprises all the data detected by the parameter detection device at this time, and the master module performs conversion processing according to the data, so as to convert the data into a format that can be broadcasted or displayed, and then broadcast or display the data.

[0054] In the preferred embodiment of the application, when the received voice instruction is the inquiry instruction for inquiring the voltage, the master module receives the data of the parameter detection device returned by the programmable controller and decodes the data, compares the obtained voltage value with the normal voltage range set in the master module, and if the voltage value is within the range, it represents that the voltage value is normal, and if the voltage value is not within the range, it represents that the voltage value is abnormal.

[0055] The engineering equipment self-checking and state query system of the application installs the master control module in the cab of the engineering equipment, and the voice recognition unit thereof can be used to receive the voice password of the operator, then identify the voice password, and send the identification result to the programmable controller. The programmable controller is installed in the electrical room of the engineering equipment, and is connected with the parameter detection device, and is responsible for obtaining the data of the parameter detection device according to the identification result, and sends the data back to the master control module. The operator can send instructions such as "query state information" or "perform self-checking" to the master control module directly through the voice password. The master control module identifies the instructions and sends them to the programmable controller for corresponding operation. The programmable controller obtains various data of the engineering equipment from the parameter detection device in real time, such as load, height, angle, speed, etc., and sends the obtained data to the master control module. After receiving the data, the master control module processes the data, such as state analysis, abnormality detection, etc. The processed data is displayed through voice broadcast and display screen, so that the operator can intuitively understand the various state information of the hoisting equipment. For example, when the operator sends the "perform self-checking" instruction through the voice password, the master control module sends the instruction identification result to the programmable controller. After receiving the instruction, the programmable controller obtains various data from the parameter detection device, such as hydraulic system pressure, motor temperature, sensor state, etc., and sends the data to the master control module. After processing the data, the master control module displays the information such as whether the hydraulic system pressure is normal, whether the motor temperature is too high, etc. to the operator through voice broadcast and display screen, so that the operator can discover and handle problems in time. The application simplifies the self-checking operation of the hoisting equipment, improves the data query efficiency, and makes the operator more intuitively understand the state information of the hoisting equipment through voice broadcast and display screen.

[0056] Optionally, the master control module further comprises a control unit, and the voice recognition unit comprises a wake-up subunit and an identification subunit.

[0057] The wake-up subunit is configured to generate a wake-up electrical signal when a wake-up instruction is received.

[0058] The identification subunit is configured to obtain the voice password from the operator and send the voice password to the control unit when the wake-up electrical signal is received.

[0059] Specifically, the control unit is usually a master chip, which can be an stm32F103ZET6 chip in the preferred embodiment of the present application. If the voice recognition unit is not used for a long time, it will enter a sleep state. If the voice recognition unit is used again after that, it needs to be woken up. At this time, the operator needs to output a wake-up instruction. When the wake-up subunit receives the wake-up instruction, it will send a wake-up electrical signal to wake up the recognition subunit, which is convenient for subsequent acquisition of the voice password. In the preferred embodiment of the present application, the operator shouts the wake-up instruction into the microphone on the master module. The wake-up subunit receives the wake-up instruction and identifies it. If the identification is successful, the green light is always on, the wake-up flag is set to "1", and if the identification fails, the wake-up flag is set to "0". When the identification is successful, the wake-up flag is "1", and the wake-up recognition subunit is woken up. Then the operator outputs the voice password into the microphone.

[0060] The engineering equipment self-checking and state querying system of the present application can wake up the voice recognition unit through simple voice instructions, making it enter a working state. This improves the user's convenience, especially in scenarios that require frequent interaction or quick response, which can improve the user experience. In addition, through the above-mentioned wake-up mechanism, interference and misidentification can be reduced, avoiding the influence of external sounds or environmental noise on the recognition result, thereby improving the accuracy and stability of voice recognition.

[0061] Optionally, the recognition subunit is specifically used for:

[0062] After receiving the wake-up electrical signal, the voice password from the operator is obtained.

[0063] If the voice password is successfully identified, the instruction code corresponding to the voice password is obtained according to the voice password, and the instruction code is sent to the control unit.

[0064] Specifically, after receiving the wake-up electrical signal, the voice password from the operator is obtained. If the voice password is successfully identified, the instruction code corresponding to the voice password is obtained according to the voice password, and the instruction code is sent to the control unit. The voice password is sent to the control unit in the form of code, for example, "0x01" is sent to the control unit as the instruction code, which is convenient for the control unit to analyze the code of the voice password and obtain the recognition result.

[0065] The engineering equipment self-checking and state querying system of the present application can actively obtain and analyze the voice password of the operator after receiving the wake-up instruction, convert it into the corresponding instruction code and send it to the control unit. This allows users to conveniently operate the device through voice commands, improves the user experience, and makes human-computer interaction more convenient.

[0066] Optionally, the control unit is configured to:

[0067] When the instruction code is received, a data protocol code is generated according to the instruction code, wherein a control frame bit of the data protocol code comprises the identification result;

[0068] The data protocol code is sent to the programmable controller through bus communication.

[0069] Specifically, when the instruction code is received, a data protocol code is generated according to the instruction code, wherein a control frame bit of the data protocol code comprises the identification result; the data protocol code is sent to the programmable controller through bus communication. In the preferred embodiment of the application, when the voice recognition unit receives a self-check instruction, when the host chip receives the instruction code "0x01", it means that the host module will encode the self-check instruction to form a "97 01 00 00 00 01 0D" data protocol code, wherein the first bit "97" of the data protocol code is the frame header, representing that the control unit sends data to the programmable controller, the second bit "01" is the instruction type, representing the self-check instruction, the third bit is the sensor type code, the fourth and fifth bits are data bits, the sixth bit is the check code, and the seventh bit is the frame tail, representing the end of the data protocol code, which is sent to the programmable controller through the RS-485 communication mode. For numerical query instructions, the data bits of the data protocol code are hexadecimal numerical values, and for state query instructions, the data bits "00 01" of the data protocol code represent normal, and "00 00" represent abnormal.

[0070] The engineering equipment self-checking and state query system of the application can automatically generate corresponding data protocol codes according to preset logic after receiving specific instruction codes, so as to realize the encoding of the self-checking instruction and improve the intelligent identification and response level of the equipment to the instruction; through the generation and transmission of the data protocol code, programmable control between the equipment is realized.

[0071] Optionally, the programmable controller is configured to:

[0072] According to the data protocol code, the identification result of the voice password is obtained;

[0073] According to the identification result, the sensing unit corresponding to the parameter detection device is determined;

[0074] The sensing data of the sensing unit is obtained, the data of the parameter detection device is obtained according to the sensing data, and the data is sent to the control unit.

[0075] Specifically, according to the data protocol code, the recognition result of the voice password is obtained; according to the recognition result, the sensing unit corresponding to the parameter detection device is determined; the sensing data of the sensing unit is acquired, and according to the sensing data, the data of the parameter detection device is obtained and sent to the main control module. In the preferred embodiment of the present application, after the programmable controller receives the data protocol code, the data protocol code is analyzed and decoded, the information of all sensing units on the crane is retrieved according to the recognition result, and the information is encoded item by item, such as: the voltage value data is encoded as "98 00 0E 01 7C 8B 0D" data protocol code, and the upper limit stopper is normally encoded as "98 00 11 01 00 20 0D" data protocol code, and is returned to the main control module as the data of the parameter detection device through the RS-485 communication mode.

[0076] The engineering equipment self-checking and state query system of the present application realizes the association of voice instructions and device operation, and through the analysis of voice password by data protocol code, the voice instructions can be matched with the corresponding sensing unit, so as to realize the intelligent control and execution of specific device operation, and improve the intelligent degree and man-machine interaction of the equipment.

[0077] Optionally, the obtaining of the data of the parameter detection device according to the sensing data comprises:

[0078] According to the sensing data, the value corresponding to the control frame bit of the data protocol code is obtained;

[0079] And according to the value, the control frame bit of the data protocol code is updated;

[0080] The updated data protocol code is taken as the data of the parameter detection device, and the data is sent to the control unit.

[0081] Specifically, according to the sensing data, the value corresponding to the control frame bit of the data protocol code is obtained; and according to the value, the control frame bit of the data protocol code is updated; and the updated data protocol code is sent to the main control module as the data of the parameter detection device. In the preferred embodiment of the present application, when the received voice instruction is a query instruction, the programmable controller receives the data protocol code and decodes it. First, the frame header, frame tail and check bit are decoded. If the frame header, frame tail and check bit are correct, it indicates that the correct instruction code is received, the instruction type is continuously decoded, the parameters of the corresponding sensing unit are obtained as sensing data according to the instruction type, and the sensing data is encoded as the value corresponding to the control frame bit, for example: the data protocol code is updated to "98 00XX XX XX XX0D" format, and then is sent back to the main control unit through RS-485.

[0082] The engineering equipment self-checking and state inquiry system of the application realizes the association of voice instructions and equipment operation, and can match voice instructions with corresponding sensing units and obtain accurate sensing data through the analysis of voice passwords by data protocol codes.

[0083] Optionally, the master control module further comprises a data display unit, which comprises a display subunit and a voice subunit.

[0084] The display subunit is used to obtain a display matrix code corresponding to the data of the parameter detection device according to the data of the parameter detection device, and display the display matrix code on a display device.

[0085] The voice subunit is used to obtain a broadcast code corresponding to the data of the parameter detection device according to the data of the parameter detection device, and broadcast the broadcast code on a broadcast device.

[0086] Specifically, the data of the parameter detection device is obtained, which may include temperature, pressure, humidity and various measurement values. The data is processed and formatted for display on a display device, such as converting the data into a specific data format or unit conversion. The processed data is converted into a corresponding display matrix code. In order to accurately display the required content on the display device. The generated display matrix code is applied to the display device to display the data of the parameter detection device through the display screen or other devices. The measurement data of the parameter detection device sensor is obtained, and the data is processed and analyzed, and the processed data is converted into a corresponding broadcast code. The broadcast code is usually a control code that can arouse the broadcast device to make corresponding voice broadcast. The generated broadcast code is applied to the corresponding broadcast device, so that the data of the parameter detection device is voice broadcast through the broadcast device.

[0087] In the preferred embodiment of the application, the voice subunit is composed of a voice broadcast circuit, which is composed of a JQ8900S chip and a storage unit. The voice broadcast circuit communicates with the control unit through UART2 to receive broadcast codes. For example, if the broadcast code is 320A current value, the control unit sends six broadcast codes "0F", "03", "0C", "02", "0B", "11" respectively. After receiving the broadcast code, the JQ8900S chip calls the voice file corresponding to the broadcast code to broadcast one by one, and the speaker emits the sound "current value three hundred and twenty amperes".

[0088] The display subunit comprises an LCD display circuit, which communicates with the control unit through SPI2. The control unit converts the data protocol code into a display matrix code and sends it to the LCD display screen. After receiving the display matrix code, the LCD display screen lights up the corresponding pixel points on the LCD display screen to form characters.

[0089] When the received voice instruction is a self-check instruction, after all data protocol codes are decoded, if all are normal values, it represents that the self-check is normal, the self-check normal information is encoded as the broadcast code of "12" "1E", and is sent to the voice subunit, the voice subunit broadcasts the corresponding voice "self-check normal" according to the broadcast code, and the self-check normal information is encoded as the display matrix code of the display device to display "self-check normal" on the display device; if there is an abnormal item in the data protocol code, such as an abnormal voltage value, it represents that the self-check is abnormal, the self-check abnormal information is encoded as the broadcast code of "12" "1F" "0E" "1E", the voice subunit broadcasts the corresponding voice "self-check abnormal voltage value abnormal" according to the broadcast code, and the self-check abnormal information is encoded as the display matrix code of the display subunit to display "self-check abnormal" "voltage value abnormal" on the display device.

[0090] The engineering equipment self-check and state query system of the application displays the data of the parameter detection device on the display device through the display matrix code and broadcasts the data on the broadcast device through the broadcast code, which helps to display the data of the parameter detection device in an intuitive and easy-to-understand manner and provides real-time information through voice broadcast when needed, thereby improving the efficiency and safety of equipment operation.

[0092] The pixel information of the display device is obtained according to the data protocol code of the data.

[0093] The display matrix code of the display device corresponding to the data is obtained according to the pixel information.

[0094] Specifically, first, the data protocol code corresponding to the data of the parameter detection device needs to be parsed, which includes the measurement values of various sensors, the state information of the equipment, etc. According to the specific information in the data protocol code, including numerical value, unit, data format, etc., the pixel information that needs to be displayed on the display device is obtained. Among them, the data needs to be decoded and formatted in order to be converted into pixel information that can be recognized by the display device. According to the obtained pixel information, the corresponding display matrix code is converted. The display matrix code is a code that represents pixel information in a specific format, which can accurately present a specific image or text on the display device.

[0095] The engineering equipment self-check and state query system of the application displays the data of the parameter detection device on the display device through the display matrix code and broadcasts the data on the broadcast device through the broadcast code, which helps to display the data of the parameter detection device in an intuitive and easy-to-understand manner.

After receiving the instruction, the programmable controller obtains each item of data from the parameter detection device, such as hydraulic system pressure, motor temperature, sensor state, etc., and sends the data to the master control module. After the master control module processes the data, it will display the information such as whether the hydraulic system pressure is normal, whether the motor temperature is too high, etc. to the operator through voice broadcast and display screen, so that the operator can discover and handle the problem in time. The application simplifies the self-checking operation of the hoisting equipment, improves the efficiency of data query, and makes the operator more intuitively understand the state information of the hoisting equipment through voice broadcast and display screen.
