[0063] The present invention provides a method, system and equipment for controlling unloading operations.

[0064] An embodiment of the present invention provides a method for controlling unloading operations. Referring to FIG. 2 , FIG. 2 is a flow chart of a first embodiment of a method for controlling unloading operations according to the present invention.

[0065] As shown in FIG2 , the unloading operation control method includes:

[0066] Step S100: when a material transport vehicle is detected to arrive at the factory, generating an unloading task according to the material transport information of the material transport vehicle;

[0067] Step S200: sending the unloading task to the preset mobile terminal corresponding to the material transport vehicle;

[0069] Step S400: Displaying the vehicle unloading operation status in real time on a preset unloading chute display terminal;

[0070] Step S500: When the unloading operation status of the vehicle meets the preset unloading completion status, the departure information is displayed through the preset unloading chute display terminal to enable the material transport vehicle to leave the site.

[0071] It should be noted that the execution entity in this embodiment may be a unloading operation control device, which may be a computer device with data processing functions, or other devices that can achieve the same or similar functions. This embodiment does not limit this. In this embodiment, a computer device is used as an example for explanation.

[0072] For example, this embodiment is described by taking the in-plant material unloading process of raw material procurement logistics of a steel enterprise as an example, and the transportation method is illustratively automobile transportation.

[0073] In one embodiment, when a material transport vehicle is detected arriving at a factory, an unloading task is generated based on the material transport information of the material transport vehicle, including: issuing a metering task to the material transport vehicle when the material transport vehicle is detected arriving at the factory; obtaining the material transport information of the material transport vehicle when the material transport vehicle completes the metering task; extracting the order number, shipping batch, and sampling batch grouping result based on the material transport information; and generating the unloading task for the material transport vehicle based on the order number, shipping batch, and sampling batch grouping result. Generating the unloading task for the material transport vehicle based on the order number, shipping batch, and sampling batch grouping result includes: assigning material transport vehicles of the same shipping batch and sampling batch to the same unloading trough and unloading batch based on the order number, shipping batch, and sampling batch grouping result; and forming the unloading task for the material transport vehicle based on the slot position of the unloading trough and the unloading batch.

[0074] Specifically, the unloading task management of material transport vehicles is carried out: when a material transport vehicle, such as a car, enters a steel plant, after the heavy vehicle measurement is carried out through the metering task, the material transport information of the material transport vehicle is obtained. The material transport information includes but is not limited to the transport order number, shipping batch, and sampling batch results, etc. The slot position of the unloading trough is allocated to the material transport vehicle according to the order number, shipping batch, and sampling batch results, forming an unloading task. It should be noted that material transport vehicles with the same shipping batch and sampling batch are allocated to the same unloading trough, forming an unloading batch. The unloading task of the material transport vehicle is formed according to the slot position of the allocated unloading trough and the determined unloading batch.

[0075] In one embodiment, the unloading task is sent to a preset mobile terminal corresponding to the material transport vehicle; it is determined whether confirmation information based on the feedback of the unloading task is received from the preset mobile terminal corresponding to the material transport vehicle; when the confirmation information is not received within a preset time, the preset mobile terminal is called through a preset communication device to make the material transport vehicle move to the unloading position based on the unloading task.

[0076] Exemplarily, the information interaction of the vehicle unloading operation includes but is not limited to interaction with the mobile application on the mobile phone of the transport vehicle driver and interaction with the vehicle unloading chute display terminal. Specifically, the preset mobile terminal corresponding to the material transport vehicle can be the mobile phone of the transport vehicle driver, which interacts with the mobile application on the mobile phone of the transport vehicle driver: the mobile application on the driver's mobile phone is bound to the mobile phone number and license plate number, and combined with the telephone robot, interaction with the driver is achieved. When the material transport vehicle is arranged to unload, the unloading task is sent to the driver's mobile phone mobile application, and the license plate number of the material transport vehicle and the corresponding slot number of the unloading chute are displayed through the mobile application, prompting the driver to go to the designated unloading chute for unloading operations. After the driver obtains the unloading task, he clicks confirm on the mobile application interface on the mobile phone to complete the information interaction. If no confirmation information is received from the driver after the preset time of issuing the unloading task (the specific preset time can be flexibly set), the telephone robot will call the driver's reserved phone number to notify the driver to perform the unloading operation.

[0077] In one embodiment, when the material transport vehicle moves to the unloading position based on the unloading task, the vehicle unloading operation status of the material transport vehicle is monitored in real time according to a preset sensing device, including: when the material transport vehicle moves to the unloading position based on the unloading task, confirming whether the material transport vehicle belongs to the current unloading task vehicle according to a preset unloading chute display terminal; if so, judging whether the material transport vehicle has moved to the target unloading position according to a preset sensing device; when the material transport vehicle is located at the target unloading position, controlling the material transport vehicle to start unloading; and monitoring the vehicle unloading operation status of the material transport vehicle in real time according to the preset sensing device.

[0078] It should be noted that a preset unloading chute display terminal is installed in front of the unloading chute. The display content of the preset unloading chute display terminal includes but is not limited to the current operating vehicle queue: used to display the vehicle license plate number in the current operating task of the unloading chute; and the dynamic QR code of the unloading operation task, etc.

[0079] In one example, the vehicle unloading operation status is displayed in real time on a preset unloading chute display terminal, including: displaying a dynamic QR code of the unloading operation task in real time on the preset unloading chute display terminal; wherein, the unloading operation task dynamic QR code is associated with the vehicle unloading operation status, and the unloading operation task dynamic QR code includes a vehicle number and an unloading operation status word corresponding to the vehicle number, and the unloading operation status word includes a first status word, a second status word, a third status word, a fourth status word and a fifth status word, the first status word corresponds to a request unloading status, the second status word corresponds to a parked in place status, the third status word corresponds to a first unloading position status, the fourth status word corresponds to a second unloading position status, and the fifth status word corresponds to a completion confirmation status.

[0080] Specifically, the dynamic QR code for the unloading task is associated with the vehicle number and the unloading status of each vehicle in the current unloading task corresponding to the unloading chute. The vehicle unloading status is described using five bits: X1, X2, X3, X4, and X5. Each status word corresponds to the following states: unloading request, parked in place, unloading position 1, unloading position 2, and completion confirmation. The values ​​of X1, X2, X3, X4, and X5 range from {0, 1}, and are initially set to 0.

[0081] For example, when a material transport vehicle arrives at the unloading location, the driver uses the scanning interface provided by the mobile app to scan the QR code on the preset unloading chute display terminal. The preset unloading chute display terminal then captures the driver's mobile phone number and license plate number. When the material transport vehicle moves to the unloading location based on the unloading task, the preset sensing device identifies the current license plate number and confirms that it is a vehicle in the task queue. The preset unloading chute display terminal then prompts "Agree to unloading, start detecting vehicle position." Simultaneously, the unloading operation status word X1 is set to 1.

[0082] In one embodiment, when the vehicle's unloading operation status meets the preset unloading completion status, a departure message is displayed on the preset unloading chute display terminal, allowing the material transport vehicle to depart. Specifically, after the vehicle has completed unloading, the driver uses the scanning interface provided by the mobile application to scan the QR code on the preset unloading chute display terminal, obtain the driver's mobile phone number and license plate number, confirm that the vehicle is in the current task queue, and that the unloading operation status characters X1, X2, X3, and X4 are 1111. Simultaneously, the preset sensing device identifies the current license plate number and confirms that the vehicle is empty. After determining that the above conditions have been met, the vehicle's unloading operation status is confirmed to meet the preset unloading completion status, and a prompt "Unloading completed, please leave safely" is displayed on the terminal. Simultaneously, the unloading operation status character X5 is set to 1.

[0083] It should be noted that a vehicle-mounted display device can also be installed on a material transport vehicle. The display content of the vehicle-mounted display device includes, but is not limited to, a vehicle operation intelligent monitoring screen and a prompt information display area. The vehicle operation intelligent monitoring screen is used to display the images of each camera set by the preset sensing device in real time, and the correct vehicle parking area is marked in a conspicuous color on the screen to assist the driver in parking the vehicle in the correct location. The prompt information display area is used to display various prompt information. It is understood that the display content can also be displayed through the driver's mobile phone mobile application, and this embodiment does not limit this.

[0084] In this embodiment, when a material transport vehicle is detected to have arrived at a factory, an unloading task is generated based on the material transport information of the material transport vehicle; the unloading task is sent to a preset mobile terminal corresponding to the material transport vehicle; when the material transport vehicle moves to the unloading position based on the unloading task, the vehicle unloading operation status of the material transport vehicle is monitored in real time according to a preset sensing device; the vehicle unloading operation status is displayed in real time on a preset unloading chute display terminal; when the vehicle unloading operation status meets the preset unloading completion status, a departure information is displayed through the preset unloading chute display terminal to allow the material transport vehicle to leave. In this embodiment, the unloading operation efficiency is improved by controlling the entire process of the unloading process, and the unloading operation is controlled and intelligently sensed by the preset sensing device and the preset unloading chute display terminal, and the unloading status is displayed in real time for easy adjustment, thereby improving the intelligence and automation of the enterprise's automobile storage and transportation business. Thus, intelligent control of automobile unloading operations is achieved based on the Internet of Things and intelligent sensing technology, solving the technical problems of low efficiency, low degree of intelligence and automation in each process of existing raw and fuel loading and unloading, and inability to monitor the working status of the unloading operation in real time.

[0085] In some embodiments, as shown in FIG3 , a second embodiment of the method for controlling unloading operations of the present invention is proposed based on the first embodiment. Step S300 includes:

[0086] Step S301: When the material transport vehicle moves to the unloading position based on the unloading task, confirm whether the material transport vehicle belongs to the current unloading task vehicle according to the preset unloading chute display terminal;

[0087] Step S302: If yes, determine whether the material transport vehicle has moved to the target unloading location according to a preset sensing device;

[0088] Step S303: When the material transport vehicle is located at the target unloading position, controlling the material transport vehicle to start unloading;

[0089] Step S304: monitoring the unloading operation status of the material transport vehicle in real time according to the preset sensing device.

[0090] It should be noted that a preset unloading chute display terminal is installed in front of the unloading chute, and the display content of the preset unloading chute display terminal includes but is not limited to the current operating vehicle queue: used to display the vehicle license plate number in the current operating task of the unloading chute; and the unloading operation task dynamic QR code, etc., wherein the unloading operation task dynamic QR code is associated with the vehicle unloading operation status, and the unloading operation task dynamic QR code includes the vehicle number and the unloading operation status word corresponding to the vehicle number, and the unloading operation status word includes a first status word, a second status word, a third status word, a fourth status word and a fifth status word, the first status word corresponds to the request unloading status, the second status word corresponds to the parked in place status, the third status word corresponds to the first unloading position status, the fourth status word corresponds to the second unloading position status, and the fifth status word corresponds to the completion confirmation status.

[0091] Specifically, the dynamic QR code for the unloading task is associated with the vehicle number and the unloading status of each vehicle in the current unloading task corresponding to the unloading chute. The vehicle unloading status is described using five bits: X1, X2, X3, X4, and X5. Each status word corresponds to the following states: unloading request, parked in place, unloading position 1, unloading position 2, and completion confirmation. The values ​​of X1, X2, X3, X4, and X5 range from {0, 1}, and are initially set to 0.

[0092] For example, when a material transport vehicle arrives at the unloading position, the driver scans the QR code on the preset unloading trough display terminal through the scanning interface provided by the mobile phone mobile application. The preset unloading trough display terminal obtains the driver's mobile phone number and license plate number. When the material transport vehicle moves to the unloading position based on the unloading task, the current license plate number is identified according to the preset sensing device, and it is confirmed that it is a vehicle in the queue for this task. The preset unloading trough display terminal prompts "Agree to unloading, start detecting the vehicle position", and at the same time sets the first status word X1 in the unloading operation status word to 1.

[0093] In one embodiment, determining whether the material transport vehicle has moved to the target unloading position according to a preset sensing device includes: acquiring a first image of the material transport vehicle according to a first camera device in the preset sensing device; determining whether the compartment of the material transport vehicle is located between a first auxiliary light and a second auxiliary light according to the first image, and whether the tail of the compartment exceeds a third auxiliary light; if so, determining that the material transport vehicle has moved to the target unloading position.

[0094] Specifically, when the value of the first status word X1 is set to 1, the automobile unloading operation process perception and recognition system, that is, the preset perception device, is used to detect whether the vehicle parking position is qualified. If it is determined that the parking is qualified, the preset unloading chute display terminal will prompt "The vehicle is parked in place and unloading can begin", and at the same time, the second status word X2 in the unloading operation status word is set to 1.

[0095] Exemplarily, the preset sensing device may include a vehicle unloading operation process sensing and recognition system as shown in FIG4 and a vehicle unloading operation sensing auxiliary light system as shown in FIG5 .

[0096] As shown in Figure 5, the vehicle unloading process perception and recognition system includes a visible line laser emitter that uses visible linear light to assist in identifying the vehicle unloading status. The visible line laser emitter sets a visible laser marking line in the vehicle unloading area to assist the vehicle unloading process perception and recognition system in detecting and identifying the vehicle's operating status. The first auxiliary light (as shown in Figure 5, auxiliary light ①), the second auxiliary light (as shown in Figure 5, auxiliary light ②), and the third auxiliary light (as shown in Figure 5, auxiliary light ③) are used to calibrate the position of the vehicle compartment. The sides of the compartment should be located between the first and second auxiliary light beams, and the rear of the compartment should extend beyond the third auxiliary light beam. The fourth auxiliary light (as shown in Figure 5, auxiliary light ④) and the fifth auxiliary light (as shown in Figure 5, auxiliary light ⑤) should be located within the sides of the compartment. The vehicle unloading process perception and recognition system, shown in Figure 4, includes three sets of cameras and fill-light devices: front, rear, and top. As shown in Figure 5, a linear laser visible light source (visible line laser emitter) is set up to project a linear visible light beam in the vehicle unloading area to assist video analysis in detecting vehicle position and unloading status.

[0097] In one embodiment, the real-time monitoring of the vehicle unloading operation status of the material transport vehicle according to the preset sensing device includes: acquiring a second image of the material transport vehicle according to the second camera device in the preset sensing device; identifying the vehicle number of the material transport vehicle according to the second image; acquiring a third image of the material transport vehicle according to the third camera device in the preset sensing device; judging the rollover angle of the carriage of the material transport vehicle according to the third image in combination with the fourth auxiliary light and the fifth auxiliary light; and real-time monitoring of the vehicle unloading operation status of the material transport vehicle according to changes in the vehicle number of the material transport vehicle and the rollover angle of the carriage.

[0098] Specifically, the upper camera captures a first image, and based on the first image, determines whether the vehicle's cabin is located between a first auxiliary light beam (such as auxiliary light beam ① in Figure 5 ) and a second auxiliary light beam (such as auxiliary light beam ② in Figure 5 ), and whether the rear of the cabin extends beyond a third auxiliary light beam (such as auxiliary light beam ③ in Figure 5 ). If these conditions are met, the vehicle's parking position is determined to have met the requirements, i.e., the material transport vehicle has been moved to the target unloading location. The front camera captures a second image, and the vehicle's license plate number is identified from the second image.

[0099] For example, a third image is captured by the rear camera and combined with the fourth and fifth auxiliary light beams to determine the vehicle's cabin tilt angle θ. As the vehicle's cabin tilt angle changes, the angles of the fourth and fifth auxiliary light beams on the cabin also change accordingly. By identifying and detecting the changes in the angles of the fourth and fifth auxiliary light beams, the vehicle's cabin tilt angle θ can be detected. Images captured by the rear camera and the upper camera are used to determine whether the vehicle is empty.

[0100] Specifically, during the vehicle unloading process, when the vehicle unloading operation process sensing and recognition system detects that the bucket has tilted to an intermediate angle θ1, a prompt is displayed on the preset unloading chute display terminal, indicating "Arrived at self-dumping position 1, unloading can continue", and the third status word X3 in the unloading operation status word is set to 1. During the vehicle unloading process, when the vehicle unloading operation process sensing and recognition system detects that the bucket has tilted to a maximum angle θ2, a prompt is displayed on the preset unloading chute display terminal, indicating "Arrived at self-dumping position 2, unloading can continue", and the fourth status word X4 in the unloading operation status word is set to 1.

[0101] In one embodiment, when the vehicle's unloading operation status meets the preset unloading completion status, a departure message is displayed on the preset unloading chute display terminal, allowing the material transport vehicle to depart. Specifically, after the vehicle has completed unloading, the driver uses the scanning interface provided by the mobile application to scan the QR code on the preset unloading chute display terminal, obtain the driver's mobile phone number and license plate number, confirm that the vehicle is in the current task queue, and that the unloading operation status characters X1, X2, X3, and X4 are 1111. Simultaneously, the preset sensing device identifies the current license plate number and confirms that the vehicle is empty. After determining that the above conditions have been met, the vehicle's unloading operation status is confirmed to meet the preset unloading completion status, and a prompt "Unloading completed, please leave safely" is displayed on the terminal. Simultaneously, the unloading operation status character X5 is set to 1.

[0102] It should be noted that the dynamic QR code of the preset unloading chute display terminal contains several random fields. Whenever the QR code is scanned successfully, the random field will be regenerated and merged with the operation information to generate a new QR code for subsequent operation identification.

[0103] For example, after a vehicle arrives at the work site, it uses a mobile app to scan a dynamic QR code displayed on a fixed terminal to confirm its work status. The dynamic QR code for the unloading task is associated with each vehicle's unloading status information and contains several random fields. Once the QR code is successfully scanned, the random fields are regenerated and combined with the work information to create a new QR code for subsequent work identification. The vehicle's location and work status are confirmed by comparing the QR code scanned by the mobile app with the QR code displayed on the fixed terminal.

[0104] In this embodiment, the vehicle unloading status is precisely identified through the vehicle unloading process perception and recognition system and the vehicle unloading operation perception auxiliary light system in the preset sensing device. By controlling the entire unloading process, unloading efficiency is improved. The preset sensing device and the preset unloading chute display terminal enable control and intelligent perception of the unloading operation, and real-time display of the unloading status facilitates adjustment. This improves the intelligence and automation of the company's vehicle storage and transportation business. This, based on the Internet of Things and intelligent sensing technology, enables intelligent control of vehicle unloading operations, resolving the technical issues of low efficiency, low intelligence and automation levels in various processes during the existing raw material loading and unloading process, and the inability to monitor the unloading operation status in real time.

[0107] The task management module 10 is used to generate an unloading task according to the material transportation information of the material transportation vehicle when detecting that the material transportation vehicle arrives at the factory;

[0108] An information interaction module 20 is used to send the unloading task to a preset mobile terminal corresponding to the material transport vehicle;

[0109] A sensing and monitoring module 30 is configured to monitor the unloading operation status of the material transport vehicle in real time according to a preset sensing device when the material transport vehicle moves to the unloading position based on the unloading task;

[0110] The terminal display module 40 is used to display the vehicle unloading operation status in real time on a preset unloading chute display terminal;

[0111] The unloading completion module 50 is used to display departure information through the preset unloading chute display terminal when the unloading operation status of the vehicle meets the preset unloading completion status, so as to enable the material transport vehicle to leave the site.

[0112] It should be noted that this embodiment is described by taking the in-plant material unloading process of raw material procurement logistics of a steel enterprise as an example, and the transportation method is illustratively automobile transportation.

[0113] In one embodiment, when a material transport vehicle is detected arriving at a factory, an unloading task is generated based on the material transport information of the material transport vehicle, including: issuing a metering task to the material transport vehicle when the material transport vehicle is detected arriving at the factory; obtaining the material transport information of the material transport vehicle when the material transport vehicle completes the metering task; extracting the order number, shipping batch, and sampling batch grouping result based on the material transport information; and generating the unloading task for the material transport vehicle based on the order number, shipping batch, and sampling batch grouping result. Generating the unloading task for the material transport vehicle based on the order number, shipping batch, and sampling batch grouping result includes: assigning material transport vehicles of the same shipping batch and sampling batch to the same unloading trough and unloading batch based on the order number, shipping batch, and sampling batch grouping result; and forming the unloading task for the material transport vehicle based on the slot position of the unloading trough and the unloading batch.

[0114] Specifically, the unloading task management of material transport vehicles is carried out: when a material transport vehicle, such as a car, enters a steel plant, after the heavy vehicle measurement is carried out through the metering task, the material transport information of the material transport vehicle is obtained. The material transport information includes but is not limited to the transport order number, shipping batch, and sampling batch results, etc. The slot position of the unloading trough is allocated to the material transport vehicle according to the order number, shipping batch, and sampling batch results, forming an unloading task. It should be noted that material transport vehicles with the same shipping batch and sampling batch are allocated to the same unloading trough, forming an unloading batch. The unloading task of the material transport vehicle is formed according to the slot position of the allocated unloading trough and the determined unloading batch.

[0115] In one embodiment, the unloading task is sent to a preset mobile terminal corresponding to the material transport vehicle; it is determined whether confirmation information based on the feedback of the unloading task is received from the preset mobile terminal corresponding to the material transport vehicle; when the confirmation information is not received within a preset time, the preset mobile terminal is called through a preset communication device to make the material transport vehicle move to the unloading position based on the unloading task.

[0116] Exemplarily, the information interaction of the vehicle unloading operation includes but is not limited to interaction with the mobile application on the mobile phone of the transport vehicle driver and interaction with the vehicle unloading chute display terminal. Specifically, the preset mobile terminal corresponding to the material transport vehicle can be the mobile phone of the transport vehicle driver, which interacts with the mobile application on the mobile phone of the transport vehicle driver: the mobile application on the driver's mobile phone is bound to the mobile phone number and license plate number, and combined with the telephone robot, interaction with the driver is achieved. When the material transport vehicle is arranged to unload, the unloading task is sent to the driver's mobile phone mobile application, and the license plate number of the material transport vehicle and the corresponding slot number of the unloading chute are displayed through the mobile application, prompting the driver to go to the designated unloading chute for unloading operations. After the driver obtains the unloading task, he clicks confirm on the mobile application interface on the mobile phone to complete the information interaction. If no confirmation information is received from the driver after the preset time of issuing the unloading task (the specific preset time can be flexibly set), the telephone robot will call the driver's reserved phone number to notify the driver to perform the unloading operation.

[0117] In one embodiment, when the material transport vehicle moves to the unloading position based on the unloading task, the vehicle unloading operation status of the material transport vehicle is monitored in real time according to a preset sensing device, including: when the material transport vehicle moves to the unloading position based on the unloading task, confirming whether the material transport vehicle belongs to the current unloading task vehicle according to a preset unloading chute display terminal; if so, judging whether the material transport vehicle has moved to the target unloading position according to a preset sensing device; when the material transport vehicle is located at the target unloading position, controlling the material transport vehicle to start unloading; and monitoring the vehicle unloading operation status of the material transport vehicle in real time according to the preset sensing device.

[0118] It should be noted that a preset unloading chute display terminal is installed in front of the unloading chute. The display content of the preset unloading chute display terminal includes but is not limited to the current operating vehicle queue: used to display the vehicle license plate number in the current operating task of the unloading chute; and the dynamic QR code of the unloading operation task, etc.

[0119] In one example, the vehicle unloading operation status is displayed in real time on a preset unloading chute display terminal, including: displaying a dynamic QR code of the unloading operation task in real time on the preset unloading chute display terminal; wherein, the unloading operation task dynamic QR code is associated with the vehicle unloading operation status, and the unloading operation task dynamic QR code includes a vehicle number and an unloading operation status word corresponding to the vehicle number, and the unloading operation status word includes a first status word, a second status word, a third status word, a fourth status word and a fifth status word, the first status word corresponds to a request unloading status, the second status word corresponds to a parked in place status, the third status word corresponds to a first unloading position status, the fourth status word corresponds to a second unloading position status, and the fifth status word corresponds to a completion confirmation status.

[0120] Specifically, the dynamic QR code for the unloading task is associated with the vehicle number and the unloading status of each vehicle in the current unloading task corresponding to the unloading chute. The vehicle unloading status is described using five bits: X1, X2, X3, X4, and X5. Each status word corresponds to the following states: unloading request, parked in place, unloading position 1, unloading position 2, and completion confirmation. The values ​​of X1, X2, X3, X4, and X5 range from {0, 1}, and are initially set to 0.

[0121] For example, when a material transport vehicle arrives at the unloading location, the driver uses the scanning interface provided by the mobile app to scan the QR code on the preset unloading chute display terminal. The preset unloading chute display terminal then captures the driver's mobile phone number and license plate number. When the material transport vehicle moves to the unloading location based on the unloading task, the preset sensing device identifies the current license plate number and confirms that it is a vehicle in the task queue. The preset unloading chute display terminal then prompts "Agree to unloading, start detecting vehicle position." Simultaneously, the unloading operation status word X1 is set to 1.

[0122] In one embodiment, when the vehicle's unloading operation status meets the preset unloading completion status, a departure message is displayed on the preset unloading chute display terminal, allowing the material transport vehicle to depart. Specifically, after the vehicle has completed unloading, the driver uses the scanning interface provided by the mobile application to scan the QR code on the preset unloading chute display terminal, obtain the driver's mobile phone number and license plate number, confirm that the vehicle is in the current task queue, and that the unloading operation status characters X1, X2, X3, and X4 are 1111. Simultaneously, the preset sensing device identifies the current license plate number and confirms that the vehicle is empty. After determining that the above conditions have been met, the vehicle's unloading operation status is confirmed to meet the preset unloading completion status, and a prompt "Unloading completed, please leave safely" is displayed on the terminal. Simultaneously, the unloading operation status character X5 is set to 1.

[0123] It should be noted that a vehicle-mounted display device can also be installed on a material transport vehicle. The display content of the vehicle-mounted display device includes, but is not limited to, a vehicle operation intelligent monitoring screen and a prompt information display area. The vehicle operation intelligent monitoring screen is used to display the images of each camera set by the preset sensing device in real time, and the correct vehicle parking area is marked in a conspicuous color on the screen to assist the driver in parking the vehicle in the correct location. The prompt information display area is used to display various prompt information. It is understood that the display content can also be displayed through the driver's mobile phone mobile application, and this embodiment does not limit this.

[0124] In this embodiment, the unloading process is fully controlled to improve the efficiency of the unloading operation. The unloading operation is controlled and intelligently sensed through a preset sensing device and a preset unloading chute display terminal, and the unloading status is displayed in real time for easy adjustment, thereby improving the intelligence and automation of the company's automobile storage and transportation business.
