TECHNICAL FIELD
[0001] The present application relates to the technical field of data processing, and in particular to an industrial vehicle warning area and warning sound control method and system based on data processing. BACKGROUND
[0002] With the advancement of electrification and intelligent technology, industrial vehicles (such as electric forklifts, AGVs, etc.) have significantly lower noise levels in the power system than traditional internal combustion engine equipment, making it difficult for personnel in the work environment to perceive their approach, resulting in a sharp increase in accident risk. Early warning systems often use fixed volume or continuous sound patterns, which meet basic safety needs but can cause noise pollution in enclosed factory areas or unoccupied areas, and are unable to adapt to complex dynamic environments.
[0003] On the other hand, complex working conditions such as multi-vehicle coordination and man-machine mixed operation in industrial scenarios require higher safety and prevention. Traditional warning mechanisms rely on a single sensor (such as displacement or speed detection), lack of multi-dimensional data fusion analysis of vehicle location, surrounding obstacle density, and environmental lighting, making it difficult to achieve precise risk classification and differentiated early warning. For example, in a high-noise workshop, a fixed volume prompt may be weakened by environmental interference, and existing systems cannot dynamically adjust the sound intensity or frequency band.
[0004] In the prior art, some industrial vehicles are equipped with a one-letter light as a warning light on the side and rear, which projects the working area range of the industrial vehicle on the ground; at the same time, a sound alarm is installed to allow people around to perceive the approach of the industrial vehicle. Patent No. CN202011460651.0 discloses a vehicle turning safety warning system, which includes: a projection device arranged on one side of the vehicle body for projecting light on the ground on one side of the vehicle body to form a dangerous warning zone containing an inner wheel difference area on the ground; a transmission device connected to the projection device for driving the projection device to move to adjust the light projection range of the projection device; the controller is electrically connected with the projection device and the transmission device; when the deflection angle of the steering wheel of the vehicle is within a predetermined deflection angle range, the controller controls the projection device to project light, and adjusts the light projection range of the projection device according to the deflection angle of the steering wheel by controlling the transmission device. The above scheme can reduce the risk of traffic accidents caused by the existence of the inner wheel difference area when the vehicle turns.
[0005] However, the braking distance of an industrial vehicle at different speeds is different, and the above-mentioned technology in the prior art cannot guarantee the safety distance of the ground projection area, cannot adjust the projection area range in real time according to the speed, and cannot automatically adjust the frequency of the sound alarm according to the speed.

[0017] In order to more clearly illustrate the technical solutions in the embodiments of the application or the related art, the following will briefly introduce the drawings needed to be used in the embodiment or related art description. Obviously, the drawings in the following description are only embodiments of the application, and those skilled in the art can obtain other drawings according to the provided drawings without any creative labor.
[0018] Figure 1 The principle block diagram of the industrial vehicle warning area and warning sound control method; Figure 2 Flow chart of the industrial vehicle warning zone and warning sound control method; Figure 3 Schematic diagram of the industrial vehicle warning zone and warning sound control system; Figure 4 Principle diagram of the industrial vehicle warning zone and warning sound control system. DETAILED DESCRIPTION
[0019] The present application will be described in detail below in conjunction with the accompanying drawings and examples: In the prior art, the angle of the linear light and the frequency of the sound alarmer on the industrial vehicle are fixed and cannot be automatically adjusted according to the speed of the vehicle. For a forklift truck traveling at high speed, pedestrians far away are still in a dangerous area and need to be warned, but the angle of the linear light and the frequency of the sound alarmer cannot be adjusted, and the driver cannot determine whether the pedestrians far away are in a dangerous area, so the driver cannot give a warning sound that is easy to notice to the pedestrians far away in advance or take braking measures, which is prone to safety accidents. When traveling at low speed, the pedestrians far away are not in a dangerous area, and if the angle is large at this time, the alarm and speed limit will still be given when there are pedestrians far away, which reduces work efficiency.
[0020] At the same time, temperature fluctuations will also cause the capacitance or resistance of the elements such as capacitors and resistors in the oscillation circuit to change. For example, the dielectric loss of the capacitor increases in a high-temperature environment, which may cause the alarm frequency to deviate or the warning light to flicker abnormally. Moreover, when in a high-temperature (greater than 60℃) environment for a long time, the circuit contacts are easy to oxidize, which increases the contact resistance. Extremely low temperature may cause the plastic shell to shrink and deform, causing internal circuit breakage and signal transmission distortion. High temperature will reduce the heat dissipation efficiency of the LED warning light, accelerate light attenuation, and indirectly affect the stability of the optical warning signal. If the alarm has insufficient heat dissipation design, it may trigger automatic frequency reduction protection when working at high frequency due to excessive temperature. When the humidity exceeds 70%RH, a water film is easy to form on the surface of the circuit board, which increases the leakage current. It may change the waveform parameters of the alarm pulse signal, causing frequency fluctuations or false triggering. High humidity environments (such as 85%RH) will accelerate the corrosion of metal contacts, increasing the contact resistance. At the same time, it causes the plastic shell to expand and deform, which may squeeze the internal elements and cause frequency drift. Low humidity (<30%RH) will significantly increase the accumulation of static electricity, causing instantaneous high-voltage static electricity to break sensitive elements in the oscillation circuit, causing permanent frequency deviation. It also interferes with the digital signal processing chip, causing the warning light synchronization signal to be lost or the alarm tone to be abnormal.
[0021] Based on the above reasons, as shown in the following Figures 1-2 The industrial vehicle warning zone and warning sound control method based on data processing according to the present application comprises the following steps: S1: obtaining a real-time speed value of the industrial vehicle through a data acquisition module, and collecting working environment information of the industrial vehicle, wherein the working environment information includes a noise value, a light intensity value, and a temperature and humidity value; S2: calculating an alarm lamp angle and an alarm frequency according to the real-time speed value through a data processing module to obtain an angle adjustment amount and a frequency adjustment amount; S3: judging an angle adjustment direction and a frequency adjustment direction according to the angle range limit value and the frequency range limit value in combination with the working environment information through a limit value adjustment module; S4: adjusting the alarm lamp angle and the alarm frequency according to the angle adjustment direction and the frequency adjustment direction in combination with the angle adjustment amount and the frequency adjustment amount through an execution control module; S5: correcting the warning area and the alarm frequency of the alarm lamp and the alarm through a dynamic calibration module by using a feedback correction model in combination with a pedestrian motion trend; In the present application, in step S1, the data acquisition module uses a speed encoder to collect the real-time speed signal of the industrial vehicle in real time; at the same time, a noise sensor is used to collect the noise signal of the industrial vehicle in the working environment, a light sensor is used to collect the light intensity signal in the working environment, and a temperature and humidity composite sensor is used to collect the temperature and humidity signal in the working environment; the data acquisition module uses an analog-to-digital converter to convert the collected noise signal, light intensity signal, and temperature and humidity signal into a noise value, light intensity value, and temperature and humidity value.
[0022] In the present embodiment, the speed encoder is combined with a variety of sensors to form an environment composite sensor architecture, which realizes the synchronous collection of vehicle motion state and environmental parameters (sampling rate is greater than or equal to 1 kHz), and constructs a multi-dimensional data space; the light sensor is configured with an AGC circuit, which automatically switches the attenuation mode in a strong light environment to ensure that the light intensity detection linearity error is less than or equal to ±3%; the temperature and humidity sensor adopts a PTFE hydrophobic membrane + metal mesh shielding structure, which still maintains a 0.5℃ temperature measurement accuracy under 95%RH high humidity and-40℃ low temperature working conditions, and guarantees the reliability of extreme working condition data.
[0023] The speed encoder, noise sensor, light sensor, temperature and humidity composite sensor, and analog-to-digital converter are all common technical means for persons skilled in the art, and will not be described here.
[0024] In the present application, step S2 includes the following steps: S21: the data processing module uses a sliding window filtering algorithm in combination with a time series to denoise the real-time speed signal to obtain a smoothed speed signal; In the present embodiment, the sliding window length is adaptively adjusted according to the speed change rate (when Δv is greater than 1 m / s², the window is reduced from 20 ms to 5 ms), which can effectively suppress the signal jitter generated by sudden acceleration / braking, and improve the speed signal signal-to-noise ratio by greater than or equal to 15 dB.
[0025] S22: using a clustering detection algorithm to classify the smoothed speed signal according to the vehicle operating condition historical speed, to obtain normal speed signals and abnormal speed signals; In this embodiment, the vehicle operating condition historical speed refers to a set of actual driving speed data recorded by the vehicle within a specific time period (such as a trip, a day, or a certain period), including a timestamp, a speed value, and associated operating condition parameters (such as gear position, accelerator opening degree, load, etc.); Based on the Mahalanobis distance and the historical speed of the vehicle under different operating conditions, a speed feature space is constructed, which can identify abnormal speed fluctuations of 0.1 m / s level with a false positive rate of less than 0.5%, ensuring the effectiveness of the speed parameter.
[0026] S23: using an analog-to-digital converter to convert the normal speed signals and abnormal speed signals to obtain normal speed values and abnormal speed values; S24: according to the normal speed values combined with the set angle-time change coefficient and the initial warning light angle , a speed-angle mapping model is constructed; In this embodiment, wherein, represents the vehicle reference speed; S25: according to the normal speed values combined with the frequency adjustment threshold , the maximum value and the minimum value of the warning sound frequency, a frequency-speed response model is constructed; In this embodiment, ; S26: according to the predicted speed , the target warning light angle and the target warning sound frequency are calculated from the speed-angle mapping model and the frequency-speed response model; In this embodiment, , , is the predicted speed of the vehicle; S27: extracting the current warning light angle and the current warning sound frequency from the central processing unit (MCU) of the industrial vehicle; S28: calculating the difference between the target warning light angle and the target warning sound frequency and the current warning light angle and the current warning sound frequency to obtain the angle adjustment amount and the frequency adjustment amount ; In this embodiment, , ; The velocity-angle model uses a logarithmic function to compensate for the nonlinearity of the viewing angle change, while the frequency-velocity model uses a sigmoid function to achieve a smooth transition, avoiding abrupt changes and making the adjustment process more ergonomic.
[0027] In this embodiment, the sliding window filtering algorithm and the clustering detection algorithm are both commonly used techniques in the art, and will not be described in detail here.
[0028] In this invention, step S3 includes the following steps: S31: The limit adjustment module quantifies the working space of the industrial vehicle based on the working environment information to obtain a three-dimensional environmental space mapping model; In this embodiment, the three-dimensional environment space mapping model is shown in Table 1: Table 1 Three-dimensional environment space mapping model dimension parameter quantization level acoustic environment noise value quiet (less than 50 dB) / normal [50, 80] dB / noisy (more than 80 dB) optical environment light intensity value dim (less than 50 lux) / normal [50, 2000] lux / bright light (more than 2000 lux) thermodynamic environment temperature and humidity low temperature and low humidity (less than 10 °C, less than 30% RH) / standard working condition ([10, 60] °C, [30%, 80%] RH) / high temperature and high humidity (more than 60 °C, more than 80% RH) The working environment is discretized into a 0.1m³ voxel grid, and combined with the Octree data structure to achieve fast spatial retrieval (query latency less than 2ms), thereby improving the efficiency of environmental perception.
[0029] S32: Limits on the set angle range and frequency range limits Environmental compensation is performed to obtain the limits for angle correction range and frequency correction range; In this embodiment, angle correction refers to: automatically increasing the maximum pitch angle by 5-8° in strong light environment to enhance visibility, triggering angle change rate derating in high temperature environment (greater than 60°C), and increasing angle hysteresis compensation by 2-3° in high humidity environment (greater than 85%RH). Angle change rate derating is a mechanism that actively reduces the output power of the light generating device (existing device) and / or adjusts the motion parameters (response rate) of the light angle adjustment device (existing device) when the angle change rate exceeds a set threshold, in order to maintain control accuracy and avoid mechanical overload or heat loss. Angle hysteresis compensation is a closed-loop control method that corrects the command signal by setting a preset compensation value to address the angle lag or positioning error caused by the backlash (hysteresis) in the mechanical transmission system (such as gears or lead screws) of the headlight angle adjustment device.
[0030] In this embodiment, the maximum projection angle is automatically increased by 8° under strong light conditions, and frequency derating protection is triggered under high temperature conditions (the maximum frequency is limited to 80% of the nominal value at 60°C), thus enhancing the system's environmental adaptability.
[0031] In this embodiment, the frequency correction refers to: in a noisy environment, the high frequency band of 2000-2500 Hz is preferentially selected to improve the penetration, in a high temperature environment (greater than 60 DEG C), the maximum frequency is limited to be less than or equal to 1800 Hz to prevent the piezoelectric ceramic from failing, and in a high humidity environment (greater than 85% RH), a frequency jitter mode (±50 Hz) is started to suppress the standing wave effect. S33: the angle adjustment amount and the frequency adjustment amount are compared with the angle correction range limit value and the frequency correction range limit value respectively to determine: If the angle adjustment amount and the frequency adjustment amount are located in the angle correction range limit value and the frequency correction range limit value respectively, the current angle adjustment amount and the current frequency adjustment amount are converted into the angle control signal and the frequency control signal. If the angle adjustment amount or the frequency adjustment amount is located outside the corresponding angle correction range limit value and the frequency correction range limit value, the maximum or minimum value of the angle correction range limit value or the frequency correction range limit value is converted into the corresponding angle control signal and the frequency control signal; that is, if the adjustment amount is less than the minimum value of the corresponding correction range limit value, the minimum value of the correction range limit value is selected to be converted into the corresponding angle control signal and the frequency control signal; if the adjustment amount is greater than the maximum value of the corresponding correction range limit value, the maximum value of the correction range limit value is selected to be converted into the corresponding angle control signal and the frequency control signal. S34: according to the signs of the angle adjustment amount and the frequency adjustment amount, the angle adjustment direction and the frequency adjustment direction are determined. In this embodiment, the positive and negative signs of the angle adjustment amount and the frequency adjustment amount represent whether the dangerous area is enlarged or reduced, and whether the frequency of the sound alarm is increased or decreased.
[0032] Further, step S3 further includes the following steps: S35: a fuzzy control algorithm is used to determine the angle adjustment amplitude and the frequency adjustment amplitude according to the angle adjustment amount, the frequency adjustment amount, the angle adjustment direction and the frequency adjustment direction in combination with a three-dimensional environment space mapping model. For each adjustment amount, the adjustment amount is divided into a plurality of continuous adjustment steps, and the single adjustment amount of each adjustment step is the adjustment amplitude.
[0033] In the present application, step S4 includes the following steps: S41: the angle control ring is used by the execution control module to generate an angle direction adjustment level according to the angle adjustment direction. S42: the frequency control ring is used by the execution control module to generate a frequency direction adjustment level according to the frequency adjustment direction. In this embodiment, the angle ring adopts a position / speed double closed loop control (bandwidth 500 Hz), and the frequency ring adopts a full digital phase-locked technology (phase synchronization accuracy ±0.5 DEG), to realize a millisecond level response.
[0034] The hierarchy refers to the execution priority and frequency of different control loops in the control system. High-level loops are responsible for macroscopic and slow-changing instructions, and low-level loops are responsible for microscopic and fast-changing execution, forming a hierarchical and nested control structure.
[0035] S43: According to the angle direction adjustment level combined with the angle control signal, the angle of the warning light is adjusted, and according to the frequency direction adjustment level combined with the frequency control signal, the frequency of the warning sound is adjusted; S44: According to the vehicle working condition, the angle control loop and the frequency control loop are controlled to obtain a dynamic working condition parallel table; In this embodiment, the angle control loop: based on the subdivision driving technology (1 / 256 microsteps) of the stepper motor, 0.07° angle resolution is realized, and the response time is less than or equal to 50ms; The frequency control loop: deploy the DDS direct digital synthesis technology, support 1Hz frequency step precision, phase noise less than or equal to-80dBc / Hz@1kHz offset; Emergency condition: priority is given to frequency adjustment response (trigger time less than 20ms) in emergency braking scene; angle-frequency parallel adjustment mode is adopted in normal working condition; S45: According to the angle adjustment amplitude and the frequency adjustment amplitude combined with the dynamic working condition parallel table, the warning light angle and the warning sound frequency adjusted are nonlinearly compensated to obtain the warning light redundant angle and the warning sound redundant frequency; In this embodiment, according to the dynamic working condition parallel table, a harmonic distortion compensation table (THD less than 1%) is established to pre-distort the correction of the stepper motor cogging effect and the loudspeaker frequency response curve, and the linearity of the actuator is improved.
[0036] S46: Adopting PID algorithm combined with sliding sampling window, the precision error of the warning light angle and the warning sound frequency adjusted is analyzed to obtain the adjustment precision evaluation table.
[0037] In the present application, the step S5 comprises the following steps: S51: The dynamic calibration module analyzes the warning light and the warning device to obtain device information; In this embodiment, the device includes warning light information and warning device information; the warning light information includes the number of lamp beads, the brightness of the lamp beads and the layout of the lamp beads; the warning device information includes the number of loudspeakers and the layout of the loudspeakers; S52: The dynamic calibration module uses laser radar to capture the motion of pedestrians within X meters of the warning area of the industrial vehicle to construct a human motion model; S53: Adopting quaternion solution algorithm to decouple the posture of the human motion model to obtain a motion decomposition time sequence table; In this embodiment, Mahony complementary filtering algorithm is adopted, and the attitude angle accuracy is still 0.5 degrees in a vibration environment, the calculation time is less than 1 ms, and the real-time requirement is met.
[0038] S54: The dynamic calibration module generates a device operation control sequence table according to the action decomposition time sequence table, the adjustment accuracy evaluation table and the device information by using a feedback correction model; In this embodiment, the CNN-LSTM network realizes motion trajectory prediction within 200 ms, the prediction weight of the key joint (hand / head) is improved by combining the attention mechanism, and the obstacle avoidance success rate is improved by 35%.
[0039] S55: The dynamic calibration module generates a device operation sequence control signal according to the device operation control sequence table, and combines the warning light redundancy angle and the warning sound redundancy frequency to complete the warning area and warning sound control of the industrial vehicle.
[0040] In this embodiment, the basic frequency in the device operation control sequence table is modulated according to the warning sound redundancy frequency, that is, the basic frequency is floated by a proportion of the redundancy coefficient, and the pulse modulation frequency is increased. According to the warning light redundancy angle, the standard beam angle in the device operation control sequence table is modulated, that is, the warning light redundancy angle is superimposed, and the actual beam coverage range of the warning light is calculated. For example, the standard beam angle is 120°, the redundancy angle is 30°, and the final control signal instruction beam angle is adjusted to 150°.
