Description

Technical Field

[0001] This invention relates to the technical field of power unit modules, and specifically to an integrally hoisted power unit module for unmanned vehicles. Background Technology

[0002] Application document CN117466156A discloses a power control system and method for a lifting device. This system obtains the activation command of the lifting device in real time by setting a remote throttle switch. Once a remote throttle switch signal is generated, it indicates that the lifting device needs to be activated and used. However, since the truck is normally in a non-neutral position, directly transmitting the non-neutral signal to the engine lifting control unit via the neutral switch will not successfully activate the lifting device. By reversing the neutral switch signal with a reverse switch, a reversed neutral signal is obtained, that is, the truck's current non-neutral signal is reversed to a neutral signal, so that the engine lifting control unit can successfully activate the lifting device according to the reversed neutral signal. Furthermore, since the truck is in gear, it can also provide power to the lifting device.

[0003] Existing technologies utilize static adjustment methods, which result in fixed operations and a lack of flexibility. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by proposing an integrated hoisting power unit module for unmanned vehicles.

[0005] The present invention adopts the following technical solution:

[0006] An integrated hoisting power unit module for an unmanned vehicle includes a hoisting module, a hoisting information storage module, an analysis module, a control module, and a data processing module. The hoisting module is used for hoisting. The hoisting information storage module stores relevant hoisting information and transmits it to the control module. The analysis module analyzes and derives relevant information about hoisting wind speed and ambient temperature, and transmits this information to the control module. The control module derives a preset hoisting time indicator based on the relevant hoisting information, wind speed, and ambient temperature, and transmits this preset time indicator to the data processing module. The data processing module compares the preset hoisting time indicator with the hoisting information. The system selects a threshold range for the preset hoisting time indicator. When the preset hoisting time indicator is within this range, no signal is sent, and the hoisting module operates normally. When the preset hoisting time indicator exceeds the maximum value of the selected threshold range, a signal indicating that the output power needs to be increased is sent to the hoisting module. Upon receiving this signal, the hoisting module adjusts its output power. When the preset hoisting time indicator is less than the minimum value of the selected threshold range, a signal indicating that the output power needs to be decreased is sent to the hoisting module. Upon receiving this signal, the hoisting module adjusts its output power.

[0007] Optionally, the hoisting information storage module stores the required lifting height, the distance between the hoisting module and the vehicle, the preset hoisting speed, the weight of the hoisting module, the maximum load of the vehicle, the maximum hoisting speed, the ideal hoisting temperature, and transmits this information to the control module. The analysis module analyzes and derives the correction factor for the hoisting wind speed and the measured value of the hoisting ambient temperature, and transmits this information to the control module. The control module then determines the temperature adjustment based on the measured value of the hoisting ambient temperature, the ideal hoisting temperature, and the maximum hoisting temperature. The lifting time index is calculated based on the following factors: the wind speed adjustment factor is derived from the correction factor for the lifting wind speed and the maximum value of the lifting speed; the load adjustment factor is derived from the weight of the lifting module and the maximum load of the vehicle; and the preset lifting time index is derived from the following factors: the required lifting height, the distance between the lifting module and the vehicle, the preset value of the lifting speed, the load adjustment factor, the weight of the lifting module, the maximum load of the vehicle, the wind speed adjustment factor, the correction factor for the lifting wind speed, the maximum value of the lifting speed, the temperature adjustment factor, the ideal value of the lifting temperature, and the maximum value of the lifting temperature.

[0008] Optionally, the analysis module includes a wind speed analysis submodule and a temperature detection submodule; the wind speed analysis submodule is used to analyze and obtain the correction factor for the hoisting wind speed and transmit it to the control module; the temperature detection submodule is used to detect and obtain the measured value of the hoisting environment temperature and transmit it to the control module.

[0009] Optionally, when calculating the preset hoisting time target, the control module satisfies the following formula: Among them, T opt The lifting operation is pre-set with a time target, z represents the required lifting height, l represents the distance between the lifting module and the vehicle, and v represents the distance between the lifting module and the vehicle. avg Zl is the preset value for hoisting speed, and W is the load adjustment factor. mod For the weight of the hoisting module, w max The maximum load that the vehicle can lift is given by fs, where fs is the wind speed adjustment factor, and v is the maximum load that the vehicle can lift. wind v is the correction factor for the hoisting wind speed. max The maximum hoisting speed is given by t, where wd is the temperature adjustment factor and t is the maximum hoisting speed. am The measured value of the ambient temperature during hoisting, t opt For the ideal hoisting temperature, t max This represents the maximum hoisting temperature.

[0010] The beneficial effects achieved by this invention are:

[0011] 1. Real-time optimization of hoisting power has been achieved, improving work efficiency, resource utilization and overall flexibility;

[0012] 2. Dynamically adjust power to avoid operational risks caused by environmental changes or improper load.

The following embodiments will further describe the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of protection of the present invention.

[0022] Example 1: This example provides an integrated hoisted power unit module for an unmanned vehicle, combined with... Figures 1 to 3 As shown.

[0023] An integrated hoisting power unit module for an unmanned vehicle includes a hoisting module, a hoisting information storage module, an analysis module, a control module, and a data processing module. The hoisting module is used for hoisting. The hoisting information storage module stores relevant hoisting information and transmits it to the control module. The analysis module analyzes and derives relevant information about hoisting wind speed and ambient temperature, and transmits this information to the control module. The control module derives a preset hoisting time indicator based on the relevant hoisting information, wind speed, and ambient temperature, and transmits this preset time indicator to the data processing module. The data processing module compares the preset hoisting time indicator with the hoisting information. The system selects a threshold range for the preset hoisting time indicator. When the preset hoisting time indicator is within this range, no signal is sent, and the hoisting module operates normally. When the preset hoisting time indicator exceeds the maximum value of the selected threshold range, a signal indicating that the output power needs to be increased is sent to the hoisting module. Upon receiving this signal, the hoisting module adjusts its output power. When the preset hoisting time indicator is less than the minimum value of the selected threshold range, a signal indicating that the output power needs to be decreased is sent to the hoisting module. Upon receiving this signal, the hoisting module adjusts its output power.

[0024] Specifically, the selection threshold range for the pre-set hoisting time index shall be set by those skilled in the art.

[0025] Optionally, the hoisting information storage module stores the required lifting height, the distance between the hoisting module and the vehicle, the preset hoisting speed, the weight of the hoisting module, the maximum load of the vehicle, the maximum hoisting speed, the ideal hoisting temperature, and transmits this information to the control module. The analysis module analyzes and derives the correction factor for the hoisting wind speed and the measured value of the hoisting ambient temperature, and transmits this information to the control module. The control module then determines the temperature adjustment based on the measured value of the hoisting ambient temperature, the ideal hoisting temperature, and the maximum hoisting temperature. The lifting time index is calculated based on the following factors: the wind speed adjustment factor is derived from the correction factor for the lifting wind speed and the maximum value of the lifting speed; the load adjustment factor is derived from the weight of the lifting module and the maximum load of the vehicle; and the preset lifting time index is derived from the following factors: the required lifting height, the distance between the lifting module and the vehicle, the preset value of the lifting speed, the load adjustment factor, the weight of the lifting module, the maximum load of the vehicle, the wind speed adjustment factor, the correction factor for the lifting wind speed, the maximum value of the lifting speed, the temperature adjustment factor, the ideal value of the lifting temperature, and the maximum value of the lifting temperature.

[0026] Optionally, the analysis module includes a wind speed analysis submodule and a temperature detection submodule; the wind speed analysis submodule is used to analyze and obtain the correction factor for the hoisting wind speed and transmit it to the control module; the temperature detection submodule is used to detect and obtain the measured value of the hoisting environment temperature and transmit it to the control module.

[0027] Optionally, when calculating the preset hoisting time target, the control module satisfies the following formula: Among them, T opt The lifting operation is pre-set with a time target, z represents the required lifting height, l represents the distance between the lifting module and the vehicle, and v represents the distance between the lifting module and the vehicle. avg Zl is the preset value for hoisting speed, and W is the load adjustment factor. mod For the weight of the hoisting module, w max The maximum load that the vehicle can lift is given by fs, where fs is the wind speed adjustment factor, and v is the maximum load that the vehicle can lift. wind v is the correction factor for the hoisting wind speed. max The maximum hoisting speed is given by t, where wd is the temperature adjustment factor and t is the maximum hoisting speed. am The measured value of the ambient temperature during hoisting, t opt For the ideal hoisting temperature, t max This represents the maximum hoisting temperature.

[0028] Optionally, the control module may perform calculations that satisfy the following formula:

[0029] When the control module calculates the preset hoisting time target, refer to the following program code:

[0030]

[0031]

[0032]

[0033] Specifically, the unit of the hoisting preset time index is seconds. By calculating the hoisting preset time index, the hoisting process time can be predicted, reducing downtime during operation, allowing for more reasonable equipment arrangement, reducing resource waste, and improving customer experience.

[0034] In this embodiment, the value range of the correction factor for hoisting wind speed is set to be greater than 0 to less than or equal to 50. The specific value of the correction factor for hoisting wind speed is set by those skilled in the art based on the hoisting wind speed. The higher the hoisting wind speed, the lower the hoisting stability and to some extent affect the preset hoisting time index. Therefore, when the hoisting wind speed is higher, the corresponding correction factor for hoisting wind speed will also increase.

[0035] The unit for the lifting height is meters.

[0036] The distance between the lifting module and the vehicle is measured in meters. The distance between the lifting module and the vehicle can be understood as the distance between the bottom of the hook and the center of the vehicle chassis before the lifting module is lifted. Before the lifting module is lifted, the hook is suspended but has not yet started to rise into the air. At this time, the staff can measure it on-site.

[0037] The preset value for the hoisting speed is in meters per second, and it is set by those skilled in the art.

[0038] The weight of the hoisting module is measured in kilograms. It refers to the total weight of the entire module (including core components such as the power system, battery, drive unit, cooling system, and external structural components), which can be found by consulting the relevant factory parameters.

[0039] The maximum load that the vehicle can lift is measured in kilograms, which can be found by checking the relevant factory specifications.

[0040] The maximum hoisting speed is measured in meters per second. It can be understood as the maximum speed that hoisting can achieve under conditions of no external interference (wind speed, temperature, and load). It can be tested in a controlled environment to record the performance of hoisting under conditions of no external interference.

[0041] The units for the measured hoisting ambient temperature, the ideal hoisting temperature, and the maximum hoisting temperature are all in degrees Celsius. The ideal hoisting temperature refers to the optimal operating temperature of the hoisting module, which can be found by consulting the relevant factory parameters. The maximum hoisting temperature refers to the maximum tolerable temperature of the hoisting module. Exceeding this temperature will pose a safety hazard, which can also be found by consulting the relevant factory parameters.

[0042] This embodiment solves the problem of low flexibility of traditional power unit modules, realizes real-time optimization of hoisting power, and improves work efficiency, resource utilization and overall flexibility.

[0043] The above units are just examples. Those skilled in the art can set different units according to actual needs when implementing this solution.

[0044] Example 2: This example includes all the content of Example 1, and provides an integrated hoisting power unit module for unmanned vehicles to further optimize the correction factor for hoisting wind speed, combined with... Figures 4 to 7 As shown.

[0045] An integrated hoisting power unit module for an unmanned vehicle includes a wind speed analysis submodule comprising an anemometer, an information setting unit, a visual detection unit, a shape analysis unit, a pollutant analysis unit, and a calculation unit.

[0046] The anemometer is used to detect and obtain the measured value of the hoisting wind speed each time it is detected, and transmit it to the computing unit;

[0047] The information setting unit is used to set the detection accuracy of the anemometer and the weight of the item to be hoisted, and then transmits the information to the calculation unit.

[0048] The visual inspection unit is used to detect and determine the maximum height of the item to be hoisted, and then transmit it to the calculation unit;

[0049] The shape analysis unit analyzes and derives the shape factor of the item to be hoisted, and then transmits it to the calculation unit;

[0050] The pollutant analysis unit is used to analyze and obtain the measured values ​​of environmental pollutant concentrations, and then transmit them to the calculation unit;

[0051] The calculation unit calculates the hoisting environmental pollution factor based on the measured value of the environmental pollutant concentration, calculates the total number of wind speed detections based on the maximum height of the object to be hoisted and the weight of the object to be hoisted, and calculates the hoisting wind speed correction factor based on the total number of wind speed detections, the measured value of the hoisting wind speed detected each time, the detection accuracy of the anemometer, the shape factor of the object to be hoisted and the hoisting environmental pollution factor, and transmits it to the control module.

[0052] Optionally, the visual inspection unit includes an image acquisition unit, an image preprocessor, a target recognizer, and a data processor;

[0053] Image acquisition devices are used to acquire multi-angle images of items to be hoisted;

[0054] Image preprocessors perform noise reduction on images;

[0055] The target recognizer identifies the items to be hoisted using image processing algorithms and marks their bounding boxes in the image;

[0056] The data processor acquires image data of the object to be hoisted, converts the image data into height data in a three-dimensional coordinate system, extracts the maximum value from the height data and outputs it as the maximum height of the object to be hoisted, and transmits the maximum height of the object to be hoisted to the calculation unit.

[0057] Optionally, the shape analysis unit includes a scanner, a 3D modeler, a feature extractor, and a shape factor analyzer;

[0058] The scanner is used to scan the items to be hoisted and obtain point cloud data of the items to be hoisted;

[0059] The 3D modeler generates a 3D model of the object to be hoisted based on point cloud data;

[0060] The feature extractor calculates the volume and surface area of ​​the object to be hoisted using point cloud data, and extracts the maximum length, maximum width, maximum height, minimum length, minimum width, and minimum height of the object to be hoisted from the 3D model;

[0061] The shape factor analyzer calculates a first ratio based on the volume and surface area of ​​the object to be lifted, and a second ratio based on the maximum length, maximum width, maximum height, minimum length, minimum width, and minimum height of the object to be lifted. The first ratio is equal to the surface area of ​​the object to be lifted divided by its volume. The second ratio is equal to the product of the maximum length, maximum width, and maximum height of the object to be lifted, divided by the product of the minimum length, minimum width, and minimum height of the object to be lifted. When the first ratio is less than or equal to 6 and the second ratio is less than or equal to 1.2, the shape factor of the object to be lifted is calculated to be 1. In other cases, the shape factor is calculated to be 1.15, and the corresponding shape factor of the object to be lifted is transmitted to the calculation unit.

[0062] Optionally, when calculating the correction factor for the hoisting wind speed, the calculation unit satisfies the following formula:

[0063]

[0064] Where B represents the total number of wind speed measurements, and ws b The measured value of the hoisting wind speed detected in the bth time is wc, the detection accuracy of the anemometer is shape, and shape is the shape factor of the object to be hoisted. Shape can take the following values: shape = 1 or shape = 1.15. When shape = 1, it means that the shape of the object to be hoisted is regular. In other cases, shape = 1.15. wr is the hoisting environmental pollution factor.

[0065] h is the maximum height of the item to be hoisted, and dz is the weight of the item to be hoisted;

[0066] kl represents the measured concentration of environmental pollutants.

[0067] When performing calculations, refer to the following program code:

[0068]

[0069]

[0070] Specifically, the unit of each measured hoisting wind speed is meters per second; the anemometer's detection accuracy can be determined by querying, for example, if the corresponding accuracy is found to be ±0.1 meters per second, then the corresponding anemometer's detection accuracy value is 0.1; the purpose of adding the shape factor of the object to be hoisted is that when the object to be hoisted is irregularly shaped, it will have an asymmetrical effect on the airflow, leading to local wind speed differences, thus affecting the overall detection accuracy; the unit of the maximum height of the object to be hoisted is meters; the unit of the weight of the object to be hoisted is kilograms; the measured value of environmental pollutant concentration is for PM2.5 particles, when the environmental... When the measured concentration of pollutants is high, the anemometer reading will be lower than expected for the following reasons: Pollutants in the air increase the overall density of the air. When the air density increases, the airflow speed of the same volume will be slower, resulting in a lower wind speed measurement. The presence of pollutants changes the viscosity of the air. Increased air viscosity means that airflow becomes more difficult, and the slip resistance of the airflow increases, which may slow down the wind speed. The distribution of air pollutants in the atmosphere is often uneven, which may form local airflow turbulence or eddies around the anemometer. This irregular flow may also cause the anemometer to measure a lower wind speed.

[0071] The above units are just examples. Those skilled in the art can set different units according to actual needs when implementing this solution.

[0072] This embodiment solves the problem of poor flexibility of traditional power unit modules by dynamically determining the number of wind speed detections, thus ensuring detection accuracy and operational safety.

[0073] The content disclosed above is only a preferred and feasible embodiment of the present invention, and is not intended to limit the scope of protection of the present invention. Therefore, all equivalent technical changes made based on the content of the present invention specification and drawings are included within the scope of protection of the present invention. Furthermore, the elements therein can be updated as technology develops.
