Description

Technical Field

[0001] The present invention relates to an intelligent vehicle loading station system and method, an automated transportation mechanical device, and an intelligent bulk material loading system and method. Background Art

[0002] Traditional truck loading stations are simply a collection of equipment. These devices are isolated and lack signal communication, requiring communication via voice communication systems such as wired telephones or intercoms. Manual operation is required to coordinate the various devices, a manual process that not only requires a large number of personnel but is also prone to human error, resulting in low efficiency. When storing bulk materials, it is difficult to accurately determine the load capacity of the loading vehicle. To ensure sufficient material reserves during loading and avoid waiting, the buffer silos used to store the materials are typically larger, typically larger than the capacity of at least two single vehicles. This increase in the buffer silo means an increase in the height of the entire steel structure. Due to safety and strength considerations, this increase in the steel structure also increases the construction cost of the loading station. Therefore, improving the efficiency of the loading system and reducing construction costs are issues that need to be addressed. Summary of the Invention

[0003] To overcome the challenges of the existing technology, the present invention proposes an intelligent vehicle loading station system and method. This system and method integrates all the necessary equipment for vehicle loading, including storage, transportation, loading, weighing, recording, and gates, and implements intelligent control to achieve fully automated, unmanned loading, improving work efficiency and construction and operating costs.

[0005] Furthermore, a command display screen and a voice prompter are provided in front of the loading space, and the command display screen and the voice prompter are connected to the controller signal.

[0006] Furthermore, the loading space entrance is provided with an entrance gate, and the loading space exit is provided with an exit gate, and the entrance gate and the exit gate are connected to the controller signal.

[0007] Furthermore, a vehicle number identifier and a vehicle type identifier are provided in front of the entrance gate, and the vehicle number identifier and the vehicle type identifier are connected to the controller signal.

[0008] Furthermore, the vehicle type identifier is a video monitor or a radar component, or a combination of a video monitor and a radar component.

[0009] Furthermore, an exit monitor is provided behind the exit gate, and the exit monitor is connected to the controller signal.

[0010] Furthermore, a loading information interaction facility is provided behind the exit gate, and the loading information interaction facility is connected to the controller signal.

[0011] Furthermore, the loading information interaction facility is provided with a display screen and an information card reader / writer, or a printer.

[0012] Furthermore, the loading status monitoring is a video monitor or a radar, or a combination of a video monitor and a radar.

[0013] An intelligent vehicle loading method for the above-mentioned loading station system, the steps of the method are as follows:

[0014] Step 1: Extract the loading plan: Extract the loading plan for this vehicle, which includes the vehicle license plate, vehicle shape, vehicle compartment dimensions, and planned loading volume. Plan the loading process based on the loading plan.

[0015] Step 2: Vehicle Identification: When a loaded vehicle enters the loading area, the vehicle license plate identifier identifies the vehicle and compares it with the previously recorded license plate number of the vehicle being loaded. Simultaneously, the vehicle model identifier identifies the size and shape of the vehicle to confirm that it is the model of the vehicle being loaded. Once the vehicle is confirmed to be the vehicle being loaded, the gate opens to allow the vehicle to pass.

[0016] Step 3, Vehicle Positioning: The loaded vehicle enters the loading space. The loading status monitor detects the position of the loaded vehicle compartment according to the loading plan and prompts the loading vehicle driver to adjust the vehicle to the starting loading position through the command display and voice prompt. At the same time, the truck scale weighs the empty vehicle and records the weight.

[0017] Step 4: Start unloading: According to the loading plan, the lifting chute descends, the buffer bin gate opens, and the material enters the weighing distributor. The weighing sensor detects the material entering the distributor and adjusts the distribution speed of the distributor according to the loading plan. The material enters the loading vehicle compartment through the distributor and chute and begins to accumulate. The height of the lifting chute is adjusted to reach the height required for continuous unloading.

[0018] Step 5, unloading process: According to the loading plan, after the material begins to accumulate in the carriage, the command display and voice prompt are timely prompted to the driver of the loading vehicle to start the vehicle forward, and the buffer bin gate and the feed speed of the distributor are adjusted according to the vehicle's forward speed. The loading vehicle's forward speed and the material accumulation status in the carriage are monitored in real time through the loading status monitor. The forward speed of the loading vehicle and the material accumulation status in the carriage are compared with the ideal loading status of each loading stage in the loading plan, and the forward speed of the loading vehicle and the buffer bin gate opening are adjusted in real time. The distributor also adjusts the feed speed of the distributor according to the current material amount in the distributor based on the weighing sensor until the expected loading amount is reached. At the same time, the weight of the entire vehicle measured on the truck scale is fed back to the controller. The controller adjusts the speed of the distributor and the buffer bin gate opening according to the change in the vehicle weight.

[0019] Step 6: Complete unloading: Close the buffer bin gate, stop the feeder, raise the lifting chute, and use the truck scale to record whether the current material loading weight reaches the expected loading capacity. If it does not reach the expected loading capacity, lower the lifting chute to refill the material.

[0020] Step 7, Record Interaction: The final material loading amount is displayed and prompted to the loading vehicle driver through the command display and voice prompt. The exit gate opens, and the exit monitor records the scene of the loading vehicle leaving. The loading vehicle drives to the loading information interaction facility. The loading vehicle driver reads and confirms the loading information on the display screen of the loading information interaction facility, then retrieves the electronic record card or paper record recording the loading information, and the loading vehicle drives away, completing the loading process.

[0021] The advantages and beneficial effects of the present invention are as follows: the present invention comprehensively arranges and optimizes the equipment required for a complete set of loading, such as storage, transportation, loading, weighing, recording, and gates, thereby reducing the intermediate storage volume, not setting a buffer bin above the quantitative bin, significantly reducing the height of the steel structure frame, and significantly reducing the construction cost of the steel structure frame. At the same time, the network is used to organically connect each independent device to form a complete intelligent automatic loading network, and this network is used to optimize the loading process, forming a unique intelligent loading method, which greatly improves the loading efficiency and reduces the loading cost.

[0027] Example 1:

[0028] This embodiment is an intelligent vehicle loading station system. Figure 1 、 2 3. This embodiment includes: a storage bin 1, a variable frequency feeder 2 provided at the bottom of the storage bin, connected to a belt conveyor 3, a head 301 of the belt conveyor disposed at the top of a loader 4, the loader being provided, from top to bottom, with a buffer bin 402 with a buffer bin gate 401 connected to the head of the belt conveyor, a distributor 403, and a lifting chute 404; a vehicle scale 405 provided at the loading station 5 below the lifting chute; a belt conveyor material conveyance volume detector 406 and a buffer bin material storage volume detector 407, respectively; a weighing sensor 408 and a material feed speed regulator provided on the distributor; a loading status monitor 409 provided above the loading station; and a vehicle speed sensor 410 provided to the side of the loading station; the variable frequency feeder, belt conveyor material conveyance volume detector, buffer bin material storage volume detector, weighing sensor, material feed speed regulator, loading status monitor, and vehicle speed sensor being signal-connected to a controller.

[0029] The system described in this embodiment has three major functions: automatic coal loading, quantitative loading, and intelligent control. The system components include:

[0030] 1. Intelligent loading system:

[0031] The intelligent loading system primarily consists of a steel tower structure, thermal insulation panels, a buffer silo, a loading feeder, a telescopic chute, a hydraulic system, a truck scale, and lifting equipment. By monitoring the buffer silo level and real-time data from a coal level sensor on the conveyor belt, the system controls the feed rate of the coal feeder, ensuring the silo contains sufficient coal for loading.

[0032] A belt feeder is installed below the surge bin, with a telescopic chute in front of it. An extended truck scale (floor scale) is installed on the ground below the chute. The scale provides real-time monitoring of the loading volume throughout the entire loading process. The feeder's coal capacity is adjusted based on each vehicle's target load and loaded volume. A lifting chute extends into the vehicle compartment to ensure coal is not spilled or leaked.

[0033] 2. Intelligent control system:

[0034] When a car (truck) enters the loading area, the intelligent control system first identifies the vehicle number. The driver then follows the designated route to the loading station. Vehicle number identification is then performed before the vehicle is weighed. The system intelligently verifies that the incoming vehicle matches the planned load and obtains the vehicle's target load information. When the vehicle reaches the loading station, a large LED screen displays driving instructions such as "forward, stop, reverse," as well as the vehicle number, target load, actual load, and alarm status. This guides the vehicle through the entire loading process, coordinated with the intelligent loading system. Once loading is complete, the driver leaves the station following the instructions on the screen and audio signals. The system automatically generates loading reports and saves the data. Operators can access historical loading records and statistics on the host computer.

[0035] The intelligent control system must enable vehicle positioning to ensure that coal is not spilled or unevenly loaded during loading. Vehicle identification includes both the vehicle number and vehicle model. The acquired data is used to set the chute's movement position and record loading information. The chute's automatic control sets the telescopic chute height based on the identified vehicle model. When an empty vehicle arrives, the chute automatically moves to the appropriate height. A laser rangefinder is used for height feedback to ensure proper execution. A control program has been developed to adjust the chute's height according to actual conditions during loading, ensuring smooth and even loading without spilling coal or exceeding the load limit.

[0036] 3. Precision weighing module:

[0037] A truck scale is used as the weighing device, which gives the load capacity in real time and inputs it into the weighing module of the intelligent control system.

[0038] 4. Intelligent management module:

[0039] Used for host computer operation and system management, it can automatically generate loading reports and has functions such as loading data statistics and query. The interface can be customized according to user needs to improve the user's comprehensive management level of the loading system.

[0040] 5. Truck scale

[0041] The electronic truck scale is mainly composed of four parts: the load-bearing platform, the weighing display instrument, the weighing sensor, and the foundation. The overall modular structure design is required. The use of digital high-precision weighing sensors ensures the measurement accuracy of the fully electronic truck scale.

[0042] 6. Other subsystems:

[0043] (1) Weighbridge data acquisition and display subsystem:

[0044] As vehicles move, the scale data collection system collects real-time weight information from the electronic scales. After analysis, the correct weight information is selected and sent to the central control system. Electronic display screens are installed at the points where incoming vehicles must pass after being weighed and sampled (the displays must be resistant to the harsh local environment, including extreme cold and high temperatures).

[0045] (2) Electronic license plate recognition subsystem:

[0046] The electronic license plate recognition system uses radio frequency identification technology (RFID) to realize vehicle identity recognition. The system dynamically collects electronic license plate information while the vehicle is moving.

[0047] (3) Video surveillance subsystem:

[0048] Cold-resistant infrared gun-type cameras are installed at the entrance and exit of the scale to monitor the vehicle weighing situation 24 hours a day, record the video, take screenshots and archive them for future reference.

[0049] (4) Gate control subsystem:

[0050] Ground sensing coil detectors and infrared sensors are used near the vehicle entrances and exits to detect the vehicle's position, and then control the electronic gear lever to automatically lift and lower the lever.

[0051] (5) Self-service human-computer interaction subsystem:

[0052] Installing speakers or display screens on the windows of the weighing room can automatically print weighing receipts, display weighing information, and enable real-time communication between staff and drivers.

[0053] (6) Vehicle management subsystem:

[0054] The system centrally processes information collected by front-end equipment to complete weighing operations. The system connects to the coal preparation plant's information management network via Ethernet and integrates into the transportation and marketing management system. Additionally, additional functions can be customized based on enterprise needs, such as query and statistics of weighing information, vehicle management, and electronic tag card management.

[0055] (7) Automatic loading subsystem:

[0056] Material conveying equipment + variable frequency feeding equipment under the product bin or storage yard ensures quantitative feeding according to system requirements and quickly transports it to the buffer bin of the intelligent loader. The automatic loading subsystem can use stepless adjustment of the feeding amount.

[0057] Example 2:

[0058] This embodiment is an improvement of the first embodiment and is a refinement of the first embodiment regarding the loading space. In front of the loading space described in this embodiment, a command display screen 411 and a voice prompt are provided. The command display screen and the voice prompt are connected to the controller signal. Figure 2 、 3 shown.

[0059] The command display can be a large-screen LED dot matrix display or an LED color display. Dot matrix displays can only display numbers and letters, while color displays can display animations. That is, the real-time status between the vehicle and the chute during loading is displayed in an animated form, allowing truck drivers to better control their vehicles.

[0060] The voice prompter can be a dedicated audio device or a built-in audio device of the LED color display screen.

[0061] Example 3:

[0062] This embodiment is an improvement of the above embodiment and is a refinement of the above embodiment regarding the loading space. The loading space entrance of this embodiment is provided with an entrance gate 412 and the loading space exit is provided with an exit gate 413. The entrance gate and the exit gate are connected to the controller signal, such as Figure 2 、 3 shown.

[0063] The entrance gate and exit gate can adopt the lifting rod gate of general parking lot. Its function is to control the vehicles entering and exiting the loading station, so that the car drivers can clearly know when they can enter and when they can exit, and it is also convenient for the system to clearly know the various time points of vehicle operation.

[0064] Example 4:

[0065] This embodiment is an improvement of the above embodiment and is a refinement of the above embodiment regarding the import gate. In front of the import gate described in this embodiment, a vehicle number identifier 414 and a vehicle type identifier 415 are provided. The vehicle number identifier and vehicle type identifier are connected to the controller signal. Figure 2 、 3 shown.

[0066] The license plate identifier can use video recognition technology to take a photo of the license plate, identify the numbers and letters on the license plate, and obtain digital information of the license plate number.

[0067] Vehicle type recognition primarily identifies the type of truck or car. While cars and trucks vary widely, they generally follow certain basic types. This can be accomplished by capturing a video image to identify the truck's appearance, then searching a database to determine the specific model. Alternatively, it can simply identify the vehicle compartment and directly obtain its dimensions for loading purposes.

[0068] Embodiment 5:

[0069] This embodiment is an improvement of the above embodiment and a refinement of the vehicle type identifier of the above embodiment. The vehicle type identifier described in this embodiment is a video monitor or a radar component, or a combination of a video monitor and a radar component.

[0070] The video monitor can use a high-definition camera or a 3D camera to shoot the overall appearance of the vehicle, or to shoot various details of the vehicle in order to obtain the characteristic information of the vehicle as a basis for loading.

[0071] The radar can be a lidar or an ultrasonic Doppler radar.

[0072] Example 6:

[0073] This embodiment is an improvement of the above embodiment and is a refinement of the above embodiment regarding the exit gate. The exit gate of this embodiment is provided with an exit monitor 416 behind the gate, and the exit monitor is connected to the controller signal. Figure 2 、 3 shown.

[0074] Exit monitoring can be done with video surveillance, which monitors the exit. The advantage of video surveillance is that it provides a chronological view of the exit's conditions, making it easier to identify any unexpected situations. However, video surveillance is not easily digitized. Therefore, for vehicles with electronic tags, electronic monitoring can also be used for exit monitoring. However, electronic monitoring cannot detect unexpected situations. Therefore, combining the two can achieve better monitoring results.

[0075] Embodiment seven:

[0076] This embodiment is an improvement of the above embodiment and is a refinement of the above embodiment regarding the exit gate. The exit gate of this embodiment is provided with a loading information exchange facility 417 behind the gate, and the loading information exchange facility is connected to the controller signal, such as Figure 2 、 3 shown.

[0077] The purpose of the loading information exchange facility installed at the exit gate is to provide the loading driver with clear loading information, such as the load quantity, the empty vehicle weight before loading, and the full vehicle weight after loading. The loading information exchange facility can be a display screen, a printer, or both, or an information card reader / writer, which can save key loading information in paper or electronic form for easy retrieval.

[0078] Embodiment 8:

[0079] This embodiment is an improvement of the above embodiment and a refinement of the loading information interaction facility of the above embodiment. The loading information interaction facility described in this embodiment has a display screen and an information card reader / writer, or a printer.

[0080] To avoid commercial disputes, after the truck is loaded, the truck driver will first see the loading information on the display screen at the loading information interaction facility. He can then swipe a card or print out the paper information to solidify the displayed loading information on a medium he can carry, so that he can search it or use it as proof of receipt of the goods.

[0081] Embodiment 9:

[0082] This embodiment is an improvement of the above embodiment and a refinement of the above embodiment regarding the monitoring of vehicle loading status. The monitoring of vehicle loading status described in this embodiment is a video monitor or a radar, or a combination of a video monitor and a radar.

[0083] Loading status monitoring, installed at the chute outlet, is a connected monitoring facility primarily used to monitor the unloading process. Video surveillance provides a visual overview of material accumulation within the vehicle, and 3D cameras can even determine the height and changes in the accumulated material. Radar monitoring, a fully digital process, primarily monitors material accumulation. Therefore, while video monitoring can detect any unexpected events, radar often struggles to do so. Therefore, combining radar and video monitoring is the best technical option, albeit at a relatively high cost.

[0084] Embodiment 10:

[0085] This embodiment is an intelligent vehicle loading method using the loading station system described in the above embodiment. The basic process of the method is:

[0086] First, information is extracted from vehicles entering the loading station, such as the loading volume, the size of the carriage, the type of vehicle, etc. Then, the size and position of the carriage are confirmed, and the loading process is planned, that is, the speed of the vehicle or the number of times the vehicle stops. Based on this information, the vehicle is controlled to move forward, or the vehicle is directed to stop or start, to achieve accurate and efficient loading.

[0087] The specific steps of the method described in this embodiment are as follows: Figure 4 As shown:

[0088] Step 1: Extract the loading plan: Extract the loading plan for this vehicle, which includes: vehicle license plate number, vehicle appearance, vehicle compartment size, and planned loading capacity. Plan the loading process according to the loading plan.

[0089] Planning the loading process is crucial, ensuring uniform loading and preventing uneven loading. This is especially true when the volume of material to be loaded closely matches the vehicle's intended capacity. Loading planning is crucial for achieving the desired level of loading. This typically requires a clear understanding of the vehicle's dimensions. This allows for precise control of the dynamic material flow during loading, ensuring both full loading and even loading.

[0090] Step 2, vehicle identification: When a loaded vehicle enters the loading area, the vehicle license plate identifier identifies the vehicle and compares it with the previously recorded license plate of the vehicle being loaded. At the same time, the vehicle model identifier identifies the size and shape of the vehicle to confirm that it is the model of the vehicle being loaded. After confirming that it is the vehicle being loaded, the gate opens to allow the vehicle to pass.

[0091] Vehicle identification is crucial. To avoid commercial disputes, misunderstandings regarding vehicle size, loading capacity, planned load, and actual load are particularly prone to occur. Therefore, vehicle identification must be completed before loading, with clear digital information. This ensures that any misunderstandings can be quickly and clearly resolved using digital information.

[0092] Step 3, vehicle positioning: The loaded vehicle enters the loading space, and the loading status monitor detects the position of the loaded vehicle compartment according to the loading plan. It prompts the driver of the loaded vehicle to adjust the vehicle to the starting loading position through the command display and voice prompt. At the same time, the truck scale weighs the empty vehicle weight and records it.

[0093] Before a truck enters a loading bay, it must be positioned to determine its exact position relative to the loading chute. Positioning is a continuous, real-time process, starting from the rear sidewall of the vehicle and working its way up to the front sidewall. The position of the vehicle, and further its position relative to the chute, can only be determined based on the position of sensors located near the fixed loading bay.

[0094] Step 4, start unloading: According to the loading plan, the lifting chute descends, the buffer bin gate opens, and the material enters the weighing distributor. The weighing sensor detects the material entering the distributor and adjusts the conveying speed of the distributor according to the loading plan. The material enters the loading vehicle compartment through the distributor and chute and begins to accumulate. The height of the lifting chute is adjusted to reach the height for continuous unloading.

[0095] Step 5, unloading process: According to the loading plan, after the material starts to accumulate in the carriage, the command display and voice prompt will prompt the driver of the loading vehicle to start the vehicle forward in a timely manner, and adjust the buffer bin gate and the feeder feeding speed according to the vehicle's forward speed. The loading vehicle's forward speed and the material accumulation status in the carriage are monitored in real time through the loading status monitor, and compared with the ideal loading status of each loading stage in the loading plan, the loading vehicle's forward speed and the buffer bin gate opening are adjusted in real time. The feeder adjusts the feeding speed of the feeder according to the current material amount in the feeder based on the weighing sensor until the expected loading amount is reached. At the same time, the weight of the whole vehicle weighed on the truck scale is fed back to the controller. The controller adjusts the speed of the feeder and the buffer bin gate opening according to the change in the weight of the whole vehicle.

[0096] Because maintaining low speeds is difficult, the loading process can involve multiple stops for unloading, or even unloading while the vehicle is moving. While multiple stops can effectively address the low speed issue, loading efficiency is significantly reduced, and the advantages of automated loading stations are limited. For uninterrupted, continuous unloading, which requires vehicles to pass through the loading bay at a steady speed, is challenging. However, by increasing the speed of vehicles passing through the bay and accelerating unloading, rapid loading can be achieved, significantly improving loading efficiency.

[0097] Step 6, complete unloading: close the buffer bin gate, stop the feeder, raise the lifting chute, and the truck scale records whether the current material loading weight reaches the expected loading capacity. If it does not reach the expected loading capacity, lower the lifting chute to replenish the material.

[0098] Due to the monitoring of multiple sensors, problems such as material shortage and overloading usually do not occur during loading. However, in order to avoid commercial disputes, a supplementary link has been added to make the loading process more adaptable to social needs.

[0099] Step 7, Record Interaction: The final material loading amount is displayed and prompted to the loading vehicle driver through the command display and voice prompt. The exit gate opens, and the exit monitor records the scene of the loading vehicle leaving. The loading vehicle drives to the loading information interaction facility. The loading vehicle driver reads and confirms the loading information on the display screen of the loading information interaction facility, then retrieves the electronic record card or paper record recording the loading information, and the loading vehicle drives away, completing the loading process.

[0100] After loading is completed, the truck drives out of the loading station from the exit gate. The driver can obtain the main information of this loading from the roadside loading information interaction facilities, including: loading quantity, loading time, etc. The driver can confirm this information by reading the information on the display screen and keep a copy of the electronic record card or paper record as proof of this loading. The loading process is now completed and the loading station welcomes the next round of loading.

[0101] Finally, it should be noted that the above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Although the present invention has been described in detail with reference to the preferred arrangement scheme, those skilled in the art should understand that the technical solution of the present invention (such as the form of the loading station, the installation and use of various sensors, the sequence of steps, etc.) can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
