Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, specifically a ride-on lawnmower with voice feedback interaction. Background Technology

[0002] With the continuous advancement of artificial intelligence technology, the outdoor service equipment sector is experiencing a wave of intelligent upgrades. Under this trend, the demand for intelligent features in ride-on lawnmowers, as a crucial type of outdoor service equipment, is becoming increasingly prominent. To achieve real-time monitoring of the lawnmower's operating status, existing technologies typically integrate two main functional modules: voice alarm and visual display. When the system detects abnormal operation or malfunction of the equipment, the voice module immediately triggers an audible and visual alarm, promptly reminding the operator to take appropriate measures. Simultaneously, the display module synchronously presents the equipment's real-time operating parameters and alarm information. For example, a lawnmower control system, as described in patent number CN107593088A, includes a main control unit, an input unit and a parameter acquisition unit electrically connected to the main control unit, and an output unit electrically connected to the main control unit. The main control unit receives input information from the input unit and the parameter acquisition unit, analyzes and processes it, and outputs it through the output unit. The output unit includes a mowing module, a voice module, a display module, and a motion control module. Another example is a walk-behind intelligent lawnmower, including a main body and a handle. The main body includes a mowing mechanism, a traveling mechanism, and a sensing mechanism. The handle has a control mechanism and an energy supply mechanism. The control mechanism houses the aforementioned lawnmower control system and is electrically connected to other mechanisms. A touchscreen is provided on the control mechanism corresponding to the display module and input unit of the control system. These features make operation more convenient for the operator, provide timely alarm information, and facilitate quick repair and maintenance. However, the aforementioned devices do not accurately locate the fault source when issuing voice alarms, resulting in low troubleshooting efficiency. Furthermore, relying on the display module to obtain the working status and view alarm information requires the operator to divert their attention from the display screen, thus affecting their perception and response to the surrounding environment, leading to lower safety. Utility Model Content

[0003] To address the problems of low fault diagnosis efficiency and low safety in existing technologies, this invention provides a ride-on lawnmower with voice feedback interaction.

Furthermore, when reporting operating status information, the instruction acquisition module transmits the received user instruction to the machine control module. The machine control module acquires the corresponding operating status information and transmits it to the offline voice library module, which then transmits the corresponding voice segment to the voice broadcast module for playback, thus achieving the broadcasting of operating status information.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only one preferred embodiment of this utility model and are only used to explain this utility model. They do not limit the scope of protection of this utility model.

[0026] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the operations (or steps) as sequential processes, many of the operations (or steps) can be performed in parallel, concurrently, or simultaneously. Furthermore, the order of the operations can be rearranged. The process can be terminated when its operation is completed, but it may also have additional steps not included in the figures; the process may correspond to a method, function, procedure, subroutine, subroutine, etc.

[0027] Example 1:

[0028] like Figure 1 As shown, a rideable lawnmower with voice feedback interaction includes a rideable lawnmower body and a whole machine control module 1 mounted on the rideable lawnmower body. The whole machine control module 1 is communicatively connected to a voice board voice module 3 via a voice board MCU2. The voice board voice module 3 is electrically connected to a voice broadcast module 6. The voice board voice module 3 is also communicatively connected to an offline voice library module 4 and an instruction acquisition module 5.

[0029] When a fault is reported, the overall control module 1 transmits the acquired fault type to the voice module 3 via the voice board MCU2. The voice module 3 then transmits the parsed fault type to the offline voice library module 4. The offline voice library module 4 transmits the matched voice segment to the voice module 3, and the voice module 3 transmits the voice segment to the voice broadcast module 6 for broadcasting, thus achieving precise fault location and reporting. Additionally, when reporting operating status information, the instruction acquisition module 5 first transmits the received user instruction to the voice module 3. The voice module 3 then transmits the parsed user instruction to the overall control module 1 via the voice board MCU2 to obtain the corresponding operating status information. The overall control module 1 then transmits the obtained operating status information to the voice module 3 via the voice board MCU2. The voice module 3 transmits the parsed operating status information to the offline voice library module 4. The offline voice library module 4 transmits the matched voice segment to the voice module 3, and the voice module 3 transmits the voice segment to the voice broadcast module 6 for broadcasting, thus achieving the broadcasting of operating status information. This improves the efficiency and safety of equipment troubleshooting.

[0030] In this embodiment, the overall control module 1 is specifically located below the seat of the riding lawnmower body to prevent accidental damage such as collisions and impacts during operation, thereby extending the service life of the overall control module 1. The voice board MCU 2, voice board voice module 3, voice broadcast module 6, offline voice library module 4, and command acquisition module 5 are specifically located near the steering wheel of the riding lawnmower body to receive commands issued by the user and facilitate the user to receive broadcast information, further improving the efficiency and safety of equipment troubleshooting.

[0031] In this embodiment, the ride-on lawnmower also includes a battery assembly for powering the ride-on lawnmower. In another embodiment, it can also be powered by an external power source or solar energy. The specific power supply method is selected according to the working environment of the ride-on lawnmower. In this embodiment, in order to reduce the space occupied by the voice interaction components (voice board MCU2, voice board voice module 3, offline voice library module 4) in the ride-on lawnmower, the voice interaction components adopt a two-layer design.

[0032] In this embodiment, the voice broadcast module 6 is a speaker and the instruction acquisition module 5 is a microphone. In some cases, the voice broadcast module 6 and the instruction acquisition module 5 can be integrated into a headset with a microphone, which can effectively avoid the loss of information during transmission. This ensures that the voice broadcast content is clearly and accurately conveyed to the user, and also ensures that the instructions issued by the user can be received by the system completely and without attenuation, further improving the efficiency and security of equipment troubleshooting.

[0033] Specifically, such as Figure 2 As shown, the voice board MCU2 includes a voice board chip U1, resistor R1, and resistor R2. The first multiplexed pin of the voice board chip U1 is connected to the RX1 pin of the voice module 3 of the voice board through resistor R1, and the second multiplexed pin of the voice board chip U1 is connected to the TX1 pin of the voice module 3 of the voice board through resistor R2.

[0034] The first multiplexed pin is PA2 / ADC1_IN2, and the second multiplexed pin is PA3 / ADC1_IN3. The PA2 / ADC1_IN2 pin of the voice board chip U1 is connected to the RX1 pin of the voice module 3 of the voice board through resistor R1, and the PA3 / ADC1_IN3 pin of the voice board chip U1 is connected to the TX1 pin of the voice module 3 of the voice board through resistor R2. By matching the line impedance through resistors R1 and R2, signal reflection is reduced. At the same time, when the input impedance of the pin of the voice module 3 of the voice board is low, the resistor can limit the current, thereby protecting the multiplexed pins of the voice board chip U1.

[0035] Specifically, such as Figure 2 As shown, the voice board MCU2 also includes resistors R3, R4, and R5, capacitor C1, connector JP1, and connector JP2. The third multiplexed pin of the voice board chip U1 is connected to the first pin of connector JP2 through resistor R4. The fourth multiplexed pin of the voice board chip U1 is connected to the second pin of connector JP2 through resistor R3. The NRST pin of the voice board chip U1 is connected to the voltage output terminal through resistor R5. The NRST pin of the voice board chip U1 is also grounded through capacitor C1. The PA pin of the voice board chip U1 is connected to the pin of connector JP1. Specifically, the third pin of connector JP2 is grounded.

[0036] In this embodiment, the third multiplexed pin is PB10 / 3TX, the fourth multiplexed pin is PB11 / 3RX, and the pins of connector JP2 not connected to any pin are grounded. Specifically, the PA pins of the voice board chip U1 are connected to the pins of connector JP1 as follows: PA14 of the voice board chip U1 is connected to pin 3 of connector JP1, PA13 of the voice board chip U1 is connected to pin 2 of connector JP1, and pin 1 of connector JP1 is connected to the voltage output terminal. In this embodiment, resistors R3 and R4 are connected in series between the multiplexed pins of the voice board chip U1 and connector JP2, limiting the current and isolating transient impacts during connector insertion and removal. Simultaneously, the PA pins of the voice board chip U1 are led out through connector JP1, allowing flexible connection to external modules and improving expandability. In this embodiment, the voice board chip U1 specifically includes 48 pins, of which VBAT, VDDA, VDD_1, VDD_2, and VDD_3 are connected to the voltage output terminal. In this embodiment, the output voltage of the voltage output terminal is 3.3V.

[0037] The fault reporting process of this utility model is as follows: After the user turns on the power switch, when the battery assembly of the ride-on lawnmower malfunctions, the voice will repeatedly announce "Battery fault" until the user resolves the fault; after the user turns on the power switch, when the circuit board motor of the ride-on lawnmower malfunctions, the voice will repeatedly announce "Travel motor fault" until the user resolves the fault; after the user turns on the power switch, when the travel motor of the ride-on lawnmower malfunctions, the voice will repeatedly announce "Mowing motor fault" until the user resolves the fault; after the user turns on the power switch, when the mowing motor of the ride-on lawnmower malfunctions, the voice will repeatedly announce "Circuit board fault" until the user resolves the fault; after the user turns on the power switch, when the headlight of the ride-on lawnmower malfunctions, the voice will repeatedly announce "Headlight fault" until the user resolves the fault; after the user turns on the power switch, when the battery assembly of the ride-on lawnmower experiences multiple faults as described above, the voice will sequentially announce these faults until the user resolves the fault. The voice feedback broadcast process of this utility model is as follows: After the user turns on the power switch, the user can wake up the voice assistant with a wake-up word. Once the voice assistant is awakened, the user can query the working status of the ride-on lawnmower according to the set voice words. The set voice words include "driving speed", "cutting speed", "cutting gear", "whether the headlights are on", "remaining battery power", "remaining working time", "working time already completed", etc. According to different user command words, the ride-on lawnmower's different modules will provide information feedback. If a ride-on lawnmower malfunction occurs during the information playback process, the voice module 3 on the voice board will immediately broadcast the malfunction prompt after the currently playing information is finished. If the ride-on lawnmower malfunctions during the user's voice command input stage, the malfunction information will be broadcast to the user first through the speaker, and the user's voice command will be muted. If the user inputs multiple voice commands simultaneously, the voice module 3 on the voice board will arrange the information according to the order of the input commands through the register, and broadcast the corresponding information to the user through the speaker in the order of the input commands.

[0038] Example 2:

[0039] like Figure 1 As shown, it also includes a voice amplification module 7, which is electrically connected to the voice module 3 on the voice board. The voice amplification module 7 performs gain processing on the information processed by the voice module 3 on the voice board, ensuring that fault broadcast information can be received even in noisy environments, and also ensuring the accuracy of user commands acquired by the overall control module 1.

[0040] Specifically, such as Figure 3As shown, the voice board voice module 3 in this embodiment differs from the voice board voice module 3 in embodiment 1 in that the voice board voice module 3 includes a voice board voice chip U2, a capacitor C2, and a capacitor C3. The SPKL+ pin of the voice board voice chip U2 is connected to the X0 pin of the voice amplification module 7 through the capacitor C2, and the SPKL- pin of the voice board voice chip U2 is connected to the Y0 pin of the voice amplification module 7 through the capacitor C3.

[0041] The voice module 3 of the voice board also includes resistors R6 and R7, connectors JP3 and JP4, resistors R8 and R9. The RX2 pin of the voice chip U2 of the voice board is connected to one pin of connector JP3 through resistor R6. The other pin of connector JP3 is connected to one end of resistor R8, and the other end of resistor R8 is connected to the RX2 pin. The TX2 pin of the voice chip U2 of the voice board is connected to one pin of connector JP4 through resistor R7. The other pin of connector JP4 is connected to one end of resistor R9, and the other end of resistor R9 is connected to the TX2 pin.

[0042] In this embodiment, the voice module 3 of the voice board is a D0XGS02S, and the voice chip U2 of the voice board specifically includes 17 pins, of which the PWM3 pin is connected to the resistor R38, and the GND pin is grounded.

[0043] In some embodiments, the voice module 3 of the voice board further includes capacitors C21, C22, and C28. The positive power supply pin of the voice chip U2 of the voice board is grounded through capacitor C21. Capacitors C21 and C22 are connected in parallel. The positive power supply of the voice chip U2 of the voice board is also grounded through capacitor C28. The output voltage of the positive power supply is 5V.

[0044] The substantial effect of this embodiment is that by amplifying the information processed by the voice board voice module 3 through the voice amplification module 7, fault broadcast information can be received even in noisy environments. At the same time, it also ensures the accuracy of user commands obtained by the whole machine control module 1, which significantly improves the efficiency and safety of equipment fault diagnosis.

[0045] Example 3:

[0046] like Figure 4As shown, the difference between the voice amplification module 7 in this embodiment and the voice amplification module 7 in embodiment 2 is that, in this embodiment, the voice amplification module 7 includes a voice amplification chip U3, resistors R10 and R11, capacitor C4, and capacitor C5. The EN pin of the voice amplification chip U3 is grounded through resistor R10, the S1 pin of the voice amplification chip U3 is grounded through resistor R11, the VCC pin of the voice amplification chip U3 is grounded through capacitor C4, and capacitors C4 and C5 are connected in parallel.

[0047] In this embodiment, the voice amplifier chip U3 is a 74HC4052D, which specifically includes 16 pins, of which the GND and VEE pins are grounded.

[0048] like Figure 1 As shown, it also includes a voice gating module 8, which is electrically connected to the voice amplification module 7. The voice amplification module 7 performs gain processing on the information processed by the voice module 3 on the voice board and then inputs it to the voice gating module 8. The voice gating module 8 selects a single channel to output information to the voice amplification module 7 for further gain processing according to priority. This avoids the problem of broadcast confusion caused by the simultaneous output of multiple voice signals, and further ensures that fault broadcast information can be received even in noisy environments. At the same time, it also ensures the accuracy of user commands obtained by the whole machine control module 1.

[0049] Specifically, such as Figure 5 As shown, the voice gating module 8 includes a voice gating chip U4, resistors R12, R13, and R14, and capacitors C6, C7, C8, and C9. The -IN pin of the voice gating chip U4 is connected to the VO1 pin of the voice gating chip U4 through capacitor C8. Capacitor C8 is connected in parallel with resistor R12. The VDD pin of the voice gating chip U4 is grounded through capacitor C6. Capacitor C6 is connected in parallel with capacitor C7. The SD pin of the voice gating chip U4 is grounded through resistor R14. The -IN pin is also connected to the Y pin of the voice amplifier chip U3 through resistor R13. The BYP pin of the voice gating chip U4 is connected to the X pin of the voice amplifier chip U3. The +IN pin and BYP pin of the voice gating chip U4 are also grounded through capacitor C9.

[0050] The substantial effect of this embodiment is as follows: the voice amplification module 7 performs gain processing on the information processed by the voice board voice module 3 and then inputs it to the voice gating module 8. The voice gating module 8 selects a single channel to output information to the voice amplification module 7 for gain processing again according to priority. This avoids the problem of broadcast confusion caused by the simultaneous output of multiple voice signals, and further ensures that fault broadcast information can be received even in noisy environments. At the same time, it also ensures the accuracy of user commands obtained by the whole machine control module 1.
