[0053] The realization, functional features and advantages of the object of the present invention will be further described in conjunction with the embodiments with reference to the drawings. Detailed Embodiments

[0054] It should be understood that the specific embodiments described herein are merely used to explain the present invention and are not used to limit the present invention.

[0055] The main solution of the embodiment of the present invention is: acquiring an image of a vehicle in the entrance area of a weighing device; when the image contains preset vehicle identification information corresponding to preset goods, controlling a first gate to open a passage opening between the entrance area and the weighing area of the weighing device; when the vehicle passes through the passage opening and reaches the weighing area, determining the weight information of the vehicle according to the detection data of the weighing device.

[0056] In the prior art, before weighing during the process of a vehicle entering the factory to pick up goods, generally the driver needs to swipe a card, and the staff will release the vehicle only when they see that the vehicle entering the factory matches the information in the card. However, such a method of manual card swiping combined with manual verification is inefficient and seriously affects the logistics efficiency.

[0057] The present invention provides the above solution, aiming to improve the efficiency of vehicle weighing so as to effectively improve the logistics efficiency.

[0058] An embodiment of the present invention provides a vehicle weighing device.

[0059] In the embodiment of the present invention, referring to Figure 1 , the vehicle weighing device includes a weighing device 1, a vehicle identity verification device 2, and a first gate 3.

[0060] The weighing device 1 has a weighing area 01. In this embodiment, the weighing device 1 specifically refers to a weighbridge. The weighing area 01 is specifically a limited area range on the weighing device 1 for effectively weighing a vehicle. Among them, more than one weighing area 01 can be pre-divided on the weighing device 1, different types of vehicles can have different sizes of weighing areas 01, and the centers of different sizes of weighing areas 01 are coincidentally set. Among them, the weighing area 01 can be enclosed on the weighing device 1 by a marker (such as tape, etc.); it can also be enclosed by corresponding detection light rays of sensors. For example, multiple groups of infrared transmitters and infrared receivers are distributed at each corner point of the weighing area 01. In a group of infrared transmitters and infrared receivers, the light rays emitted by the infrared transmitter to the infrared receiver form a virtual side of the weighing area 01, and multiple virtual sides formed by the cooperation of multiple groups of infrared transmitters and infrared receivers enclose the weighing area 01.

[0061] The vehicle identity verification device 2 includes an image recognition module, and the vehicle identity recognition device is arranged in the entrance area 02 corresponding to the weighing device 1. Specifically, the image recognition module includes a camera and a recognition unit. The shooting direction of the camera specifically faces the entrance area 02 corresponding to the weighing device 1, and is used to collect images of the vehicles in the entrance area 02 corresponding to the weighing device 1. The recognition unit can pre-store the identification information (such as license plate number, vehicle type, and / or body color, etc.) of the vehicles with legal identities. The recognition unit is connected to the camera to obtain the images collected by the camera and parse the images. If the identification of the vehicle in the entrance area 02 parsed is matched with the pre-stored identification, it can be considered that the vehicle identity verification is passed; if not, it can be considered that the vehicle identity verification fails.

[0062] The first gate 3 is communicatively connected to the vehicle identity verification device 2 and is arranged at the passage opening between the entrance area 02 and the weighing area 01. When the first gate 3 is opened, the passage opening between the entrance area 02 and the weighing area 01 is opened, and the vehicles in the entrance area 02 can move to the weighing area 01; when the first gate 3 is closed, the passage opening between the entrance area 02 and the weighing area 01 is closed, and the vehicles in the entrance area 02 are not allowed to move to the weighing area 01. The vehicle identity verification device 2 can send corresponding signals to the first gate 3 based on its verification result. Specifically, when the vehicle identity verification device 2 passes the verification, it can send a first signal to the first gate 3, and the first gate 3 opens the passage opening when receiving the first signal; when the vehicle identity verification device 2 fails the verification, it can send a second signal to the first gate 3, and the first gate 3 closes the passage opening when receiving the second signal.

[0063] In the technical solution of the embodiment of the present invention, the vehicle identity verification device 2 arranged in the entrance area 02 of the weighing device 1 verifies the vehicle identity in the entrance area 02 based on image recognition. A first gate 3 is arranged at the passage opening between the weighing area 01 and the entrance area 02 of the weighing device 1, and the passage opening can be opened or closed based on the verification result of the vehicle identity verification device 2, so as to realize the automatic verification of the vehicle identity before vehicle weighing and the control of the vehicle entering the weighing area 01 based on the verification result without manual operation, which is beneficial to improving the efficiency of vehicle weighing and thus effectively improving the logistics efficiency.

[0064] Further, in an embodiment of the vehicle weighing equipment, refer to Figure 2, the vehicle weighing device further includes a second barrier gate 4, which is arranged at the passage opening between the exit area 03 corresponding to the weighing device 1 and the weighing area 01. When the second barrier gate 4 is opened, the passage opening between the weighing area 01 and the exit area 03 is opened, and the vehicle on the weighing area 01 can drive out of the weighing area 01 through this passage opening; when the second barrier gate 4 is closed, the passage opening between the weighing area 01 and the exit area 03 is closed, and the vehicle on the weighing area 01 is not allowed to drive out of the weighing area 01 through this passage opening. Based on this, through the setting of the second barrier gate 4, it can cooperate with the first barrier gate 3 to control the entry and exit of vehicles in the weighing area 01, ensuring that the vehicle can leave the weighing area 01 only after weighing is completed, and ensuring the accuracy of the weighing result.

[0065] Specifically, in this embodiment, the first barrier gate 3 and the second barrier gate 4 are arranged on two opposite sides of the weighing area 01. In other embodiments, the first barrier gate 3 and the second barrier gate 4 can also be arranged on one side of the weighing area 01 according to actual needs, or the first barrier gate 3 and the second barrier gate 4 can refer to the same barrier gate.

[0066] The barrier gate can be a swing-arm type barrier gate or a slide-rail type barrier gate.

[0067] Further, in an embodiment of the vehicle weighing device, referring to Figures 1 to 3 , the vehicle weighing device further includes a signal lamp 5, and the first barrier gate 3 and / or the second barrier gate 4 are connected to the signal lamp 5. The signal lamp 5 can be used to prompt the opening and closing states of the first barrier gate 3 and / or the second barrier gate 4. Specifically, the signal lamp 5 includes a first signal lamp 5 and a second signal lamp 5. The first signal lamp 5 is connected to the first barrier gate 3 to prompt the opening and closing state of the first barrier gate 3. When the first barrier gate 3 is opened, the first signal lamp 5 is in the first state (such as lighting up or green light); when the first barrier gate 3 is closed, the first signal lamp 5 is in the second state (such as turning off or red light). The second signal lamp 5 is connected to the second barrier gate 4 to prompt the opening and closing state of the second barrier gate 4. When the second barrier gate 4 is opened, the second signal lamp 5 is in the first state (such as lighting up or green light); when the second barrier gate 4 is closed, the first signal lamp 5 is in the second state (such as turning off or red light). Here, through the setting of the signal lamp 5, it can be ensured that the driver on the vehicle can intuitively and clearly know whether his vehicle can enter or leave the weighing area 01.

[0068] Further, in an embodiment of the vehicle weighing device, referring to Figures 1 to 3, the vehicle weighing device further includes a detection device 6, the detection device 6 is connected to the weighing device 1, and the detection device 6 is arranged at the edge of the weighing area 01. The number and position of the detection device 6 can be set according to actual requirements. For example, the detection device 6 can be arranged at the edge of the weighing area 01 close to the entrance area 02, or can be arranged along each edge of the weighing area 01. The detection device 6 arranged at the edge of the weighing area 01 can detect whether the vehicle enters the weighing area 01, whether it is completely located in the weighing area 01, etc., so that the weighing device 1 can weigh the weight of the vehicle based on the detection of the detection device 6 to ensure the accuracy of the weighing result of the weighing device 1.

[0069] Specifically, in this embodiment, referring to Figures 1 to 3 , the number of the detection devices 6 is multiple, the edge of the weighing area 01 is composed of multiple sub-edges, and at least one of the detection devices 6 is arranged on each sub-edge. Based on this, the detection device 6 can reflect whether there is a situation where the vehicle deviates from the weighing area 01 or does not completely move into the weighing area 01, etc., and can ensure that the vehicle is completely within the weighing area 01 before weighing the weight of the vehicle, further ensuring the accuracy of the weighing result of the weighing device 1.

[0070] Specifically, in this embodiment, the detection device 6 is an infrared detection device 6. The infrared detection device 6 specifically includes an infrared emitter and an infrared receiver. The infrared emitter and the infrared receiver are respectively arranged at both ends of the edge of the weighing area 01. The infrared emitter emits light along the extension direction of the edge of the weighing area 01. When there is no vehicle at the edge of the weighing area 01, the infrared receiver at the other end can receive the light emitted by the infrared emitter; when there is a vehicle at the edge of the weighing area 01, the infrared receiver at the other end cannot receive the light emitted by the infrared emitter. Based on this, the position of the vehicle relative to the weighing area 01 can be accurately characterized by the received signal of the infrared receiver to ensure the accuracy of the measurement result of the vehicle within the weighing area 01.

[0071] Furthermore, the distance between the infrared detection device 6 and the plane where the weighing area 01 is located is greater than or equal to a first threshold and less than or equal to a second threshold, where the second threshold is greater than the first threshold. The first threshold is specifically determined according to the wheel height of the vehicle, and the second threshold is specifically determined according to the body height of the vehicle, so as to ensure that the infrared detection device 6 can detect the body of the vehicle, avoid the light passing through the gap between the wheels and affecting the accuracy of the characterization result of the position of the vehicle relative to the weighing area 01 by the infrared receiver, so as to ensure that any position on the body can be accurately characterized by the infrared detection device 6 when its projection is on the edge of the weighing area 01, and further ensure that the weight of the vehicle is measured only when the vehicle is completely within the weighing area 01, further improving the accuracy of the measurement result of the vehicle within the weighing area 01.

[0072] It should be noted that, in other embodiments, the detection device 6 can also be other types of detection devices 6, such as a pressure sensor arranged at the edge of the weighing area 01, which can effectively detect the position of the vehicle relative to the weighing area 01 based on pressure detection when the vehicle passes through the edge of the weighing area 01.

[0073] Further, in one embodiment of the vehicle weighing device, referring to Figure 3 , the vehicle weighing device also includes a rocker 7 and a power supply module (not shown) connected to the detection device 6. One end of the rocker 7 is movably mounted on the first gate 3 and is connected to the switch of the power supply module (not shown). The rocker 7 has a first trigger position and a second trigger position. The first trigger position is the position where the rocker 7 is set along the extension direction of the edge of the weighing area 01, and the second trigger position is the position where the rocker 7 intersects with the edge of the weighing area 01 and is set horizontally. When the rocker 7 moves from the first trigger position to the second air outlet position, it drives the switch to switch from the closed state to the open state. Based on this, after the first gate 3 is opened, when the vehicle enters the weighing area 01 from the entrance area 02, it passes through the two positions A and B in sequence, and B is the position on the edge of the weighing area 01. When the vehicle is at position A, the vehicle body does not contact the rocker 7. At this time, the rocker 7 is at the first trigger position, and the switch of the power supply module (not shown) connected thereto is in the off state. The power supply module (not shown) stops supplying the detection device 6, and the detection function of the detection device 6 is in the off state. When the vehicle moves to position B, the vehicle body pushes the rocker 7 from the first trigger position to the second trigger position. Driven by the transmission action of the rocker 7, the switch of the power supply module (not shown) switches from the off state to the on state, so that the power supply module (not shown) automatically supplies power to the detection device 6, so that the detection device 6 can measure the position of the vehicle relative to the weighing area 01 after being powered on during the vehicle entering the weighing area 01. In this way, through the transmission connection between the movable rocker 7 and the switch of the power supply module (not shown) of the detection device 6, it can be realized that the detection device 6 does not need to consume electric energy before the vehicle enters the weighing area 01 to save energy consumption, and the detection device 6 can automatically power on to obtain the vehicle's entry status during the vehicle entering the weighing area 01, thereby achieving an effective balance between energy saving and accurate detection.

[0074] Further, in an embodiment of the vehicle weighing device, the vehicle weighing device further includes a reset member. One end of the reset member is connected to the power supply module (not shown), and the other end of the reset member is connected to the rocker 7, so that the rocker 7 is reset from the second trigger position to the first trigger position. Specifically, in this embodiment, the reset member is a specific elastic member, such as a reset spring. In other embodiments, the reset member can also be set as other types of components according to actual needs, such as a drive structure with an electronic control recognition function, which automatically drives the rocker 7 to reset from the second trigger position to the first trigger position when it is recognized that there is no vehicle at the edge of the weighing area 01. Refer to Figure 3 , specifically, during the process of the vehicle driving from the entrance area 02 into the weighing area 01, after passing through the above-mentioned position B, it reaches the position C within the weighing area 01. The vehicle at the position C is separated from the rocker 7. Under the action of the reset member, the rocker 7 automatically resets from the second trigger position to the first trigger position. At this time, the switch of the power supply module (not shown) automatically switches from the on state to the off state under the driving action of the rocker 7, so that the detection device 6 can be timely turned off to save energy when not in use.

[0075] Further, in an embodiment of the vehicle weighing device, the vehicle weighing device further includes a plurality of photographing devices (not shown). The plurality of photographing devices (not shown) are installed above the weighing area 01 at different photographing angles. The number of the photographing devices (not shown) can be set according to actual needs, and can be 2, 3, 4, etc. Each photographing device (not shown) faces the weighing area 01 at a different angle, so as to realize photographing multi-dimensional image information of the vehicle in the weighing area 01 through the plurality of photographing devices (not shown). The photographed image information can be stored in the memory. Based on this, it is possible to accurately monitor and record the vehicle conditions in the weighing area 01 (such as the number of people in the vehicle, the number of goods, the type of goods, and / or the position of the vehicle in the weighing area 01, etc.) through the image, so that even on the basis of unmanned weighing, the vehicle conditions during the weighing process can be understood subsequently based on the images photographed by the photographing devices (not shown).

[0076] Further, the vehicle weighing device further includes a control device, which can be applied to control the above-mentioned vehicle weighing device. Specifically, the control device can be built into the above-mentioned vehicle weighing device or can be set independently of the above-mentioned vehicle weighing device. The above-mentioned weighing device 1, the camera 21 in the image recognition module, the first gate 3, the second gate 4, the detection device 6, etc. are all connected to the control device here. The above-mentioned recognition unit can be built into the control device here.

[0077] In the embodiment of the present invention, refer to Figure 4, the control device includes: a processor 1001 (such as a CPU), a memory 1002, etc. The processor 1001 and the memory 1002 are connected through a communication bus. The memory 1002 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0078] Those skilled in the art can understand that Figure 4 the device structure shown in does not constitute a limitation on the device, and it may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements.

[0079] Such as Figure 4 shown, the memory 1002, as a computer-readable storage medium, may include a vehicle weighing program. In the Figure 4 device shown, the processor 1001 can be used to call the vehicle weighing program stored in the memory 1002 and execute the relevant step operations of the vehicle weighing method in the following embodiments.

[0080] Based on the vehicle weighing device in the above embodiments, the embodiments of the present invention further provide a vehicle weighing method.

[0081] Referring to Figure 5 , an embodiment of the vehicle weighing method of the present application is proposed. In this embodiment, the vehicle weighing method includes:

[0082] Step S10, obtaining an image of the vehicle in the entrance area of the weighing device;

[0083] Specifically, the camera set in the entrance area can take pictures of the entrance area in real time or when receiving a set signal sent by the entrance area (such as a pressure signal transmitted by a pressure sensor on the ground in the entrance area) to obtain image data. Vehicle recognition is performed on the collected image data, and the image containing the characteristic image corresponding to the vehicle in the image data is used as the image of the vehicle here.

[0084] Step S20, when the image contains preset vehicle identification information corresponding to a preset cargo, controlling the first gate to open the passage between the entrance area and the weighing area of the weighing device;

[0085] The preset goods are specifically the goods that a vehicle needs to transport when entering the weighing area of the weighing device, which is pre-set. The preset goods can be set according to actual needs. The preset vehicle identification information is specifically the visual identification information (such as license plate number, body color, vehicle type, and / or number of on-vehicle personnel, etc.) on the appearance of the vehicle used to transport the preset goods. Specifically, the identification information of the goods to be transported (such as batch number and / or type of goods, etc.) and the corresponding visual identification information of the transport vehicle can be pre-determined and bound to form the preset goods and their corresponding preset vehicle identification information here.

[0086] Extract information from the image based on the information type corresponding to the preset vehicle identification information. If the extracted information matches the preset vehicle identification information, it is considered that the image contains the preset vehicle identification information corresponding to the preset goods; if the extracted information does not match the preset vehicle identification information, it is considered that the image does not contain the preset vehicle identification information corresponding to the preset goods. For example, when the preset vehicle identification information is the license plate number, the license plate information in the image can be identified and extracted. If the extracted license plate information is the same as the license plate number in the preset vehicle identification information, the image contains the preset vehicle identification information corresponding to the preset goods; otherwise, it is considered that the image does not contain the preset vehicle identification information corresponding to the preset goods.

[0087] Among them, when there are multiple types of preset goods, different preset goods correspond to different preset vehicle identification information. A database can be obtained by including multiple preset goods and their corresponding preset vehicle identification information. In the database, if any preset vehicle identification information matches the information extracted from the image, it is considered that the image contains the preset vehicle identification information corresponding to the preset goods. Among them, the preset vehicle identifications corresponding to different preset goods can be set to be the same or different according to actual needs. For example, if both goods 1 and goods 2 can be transported by truck A, then goods 1 and goods 2 can be respectively bound to the vehicle identification information of truck A.

[0088] When the image contains the preset vehicle identification information corresponding to the preset goods, it indicates that the vehicle in the current entrance area is the vehicle planned to transport the preset goods. At this time, the first gate can be controlled to open the passage between the entrance area and the weighing area, allowing the vehicle to drive from the entrance area into the weighing area for weighing.

[0089] When the preset vehicle identification information corresponding to the preset goods is not included in the image, it indicates that the vehicle in the current entrance area is not the vehicle planned to transport the preset goods. At this time, the vehicle is not allowed to enter the weighing area for weighing. On the one hand, it can avoid the vehicle from participating in the weighing operation related to the transportation of the preset goods unnecessarily and improve the logistics efficiency. On the other hand, it can enable the driver of the vehicle to know whether the vehicle needs to transport the goods provided by the goods provider corresponding to the weighing device from whether the first gate is opened, and avoid the vehicles that do not need to pull goods from staying in the nearby area of the weighing device, which is conducive to the rapid flow of the vehicles that need to pull goods and effectively improves the material efficiency.

[0090] Step S30, when the vehicle passes through the passage entrance and arrives at the weighing area, determine the weight information of the vehicle according to the detection data of the weighing device.

[0091] Among them, the weighing area here can be a preset fixed area or an area selected from multiple preset areas based on the vehicle type in the current entrance area. Specifically, since the body sizes of different vehicle types are different, different preset weighing areas can be respectively set. Based on this, the vehicle type of the vehicle in the entrance area can be identified through the above image. For example, when the area of the vehicle image in the image is greater than or equal to the set area, the vehicle type can be determined as a large truck with a large volume; when the area of the vehicle image in the image is less than the set area, the vehicle type can be determined as a small train with a small volume. The corresponding preset weighing area is obtained based on the identified vehicle type as the current weighing area.

[0092] Whether the vehicle has arrived at the weighing area can be obtained through the analysis of the detection data of the detection device set on the weighing area. For example, when taking a picture of the weighing area and there is a vehicle in the image and the vehicle is located at the designated position (such as the middle) of the weighing area, it can be considered that the vehicle has arrived at the weighing area; another example is to obtain the data detected by multiple pressure sensors set on the weighing area, calculate the center of gravity of the vehicle based on the pressure data, and if the distance between the center of gravity and the preset center of the weighing area is less than or equal to the set distance threshold, it can be considered that the vehicle has arrived at the weighing area; another example is to position the vehicle in the weighing area based on the infrared data detected by the infrared detection device set on the weighing area, and if the positioned position is within the weighing area, it can be considered that the vehicle has arrived at the weighing area.

[0093] When the vehicle reaches the weighing area and remains stationary for a set duration, the detection data of the weighing device can be obtained as the weight information of the vehicle here.

[0094] Specifically, when the vehicle is not loaded with goods, the weight information of the vehicle here can specifically refer to the net weight of the vehicle; when the vehicle is loaded with goods, the weight information of the vehicle here can specifically refer to the net weight of the vehicle and the total weight of the goods it loads.

[0095] Wherein, when the vehicle arrives within the vehicle weight area, the first gate can be controlled to close the passage opening between the entrance area corresponding to the weighing device and the weighing area, so as to prevent the vehicle from leaving the weighing area before the weighing or settlement is completed.

[0096] A vehicle weighing method proposed by an embodiment of the present invention. When the preset vehicle identification information corresponding to the preset goods is included in the vehicle diagram in the entrance area of the weighing device, the passage opening between the entrance area and the weighing area of the weighing device is opened through the first gate, so that the vehicle in the entrance area can move from the opened passage opening to the weighing area. The weighing device can detect the vehicle on the weighing area to obtain the weight of the vehicle. Based on this, as long as the preset vehicle identification information of the preset goods is set in advance, the identity verification of the vehicle to be weighed can be performed through image recognition during the entire vehicle weighing process. After the identity verification is passed, the vehicle is automatically weighed. The entire process does not require manual operation, which is beneficial to improving the efficiency of vehicle weighing, thereby effectively improving the logistics efficiency.

[0097] Further, in this embodiment, the target delivery volume corresponding to the preset goods is sent to the terminal of the vehicle provider; the vehicle identification information returned by the terminal based on the target delivery volume is received as the preset vehicle identification information. Specifically, the preset goods provider can formulate the total planned transportation volume of the preset goods to form the target delivery volume here, and send the identification information of the preset goods and its corresponding target delivery volume to the terminal of the vehicle provider (such as the goods receiver) to form corresponding planned information. The terminal of the vehicle provider can analyze based on the identification information of the vehicles available for loading by the vehicle provider recorded in the terminal and their corresponding allowed cargo loads, and obtain the identification information of the target vehicle that meets the target delivery volume. The allowed cargo load corresponding to the obtained target vehicle is greater than or equal to the target delivery volume, and the identification information of the obtained target vehicle is returned to the control device of the goods provider. The control device can bind and store the received identification information with the preset goods to form the preset vehicle identification information.

[0098] Here, before the vehicle transports the preset goods, a transportation plan is sent to the terminal of the vehicle provider in advance, so that the vehicle provider can configure the vehicle based on the planned transportation volume of the goods to be transported, avoiding the waste of unnecessary manpower and material resources caused by too many vehicles staying in the site of the goods provider when the goods are less, and realizing more optimized allocation of logistics resources; in addition, the goods provider can know in advance which vehicles will transport the goods, and perform unmanned verification of the identity of the vehicles coming to pick up the goods based on the received vehicle identification information, ensuring the accuracy of verification while improving the logistics efficiency of the goods.

[0099] Further, based on the above embodiment, another embodiment of the vehicle weighing method of the present application is proposed. In this embodiment, refer to Figure 6, the step of controlling the first gate to open the passageway between the entrance area and the weighing area of ​​the weighing device is defined as step S20a, and before step S20a, it also includes:

[0100] Step S201, when the image contains the preset vehicle identification information, obtaining the target transportation volume and the completed transportation volume of the preset goods;

[0101] The target delivery volume is specifically the total amount of the preset cargo that needs to be transported. In addition to pre-binding the preset cargo with the preset vehicle identification information, the preset cargo and its target delivery volume can also be stored in association, based on which, the target delivery volume corresponding to the preset cargo can be determined by querying the pre-stored data based on the preset vehicle identification information.

[0102] The completed transport volume is specifically recorded based on the transportation conditions of the preset goods before the current moment. For example, before the vehicle is loaded with the preset goods before the current moment, a weighing device can be used to weigh the empty vehicle weight, and after the vehicle is loaded with the preset goods, a weighing device can also be used to weigh the loaded vehicle weight. The weight deviation between the empty vehicle weight and the loaded vehicle weight can be calculated to obtain the weight of the preset goods loaded by the vehicle, and the weight is recorded once for each loading, and all the recorded weights are accumulated to obtain the completed transport volume here. Among them, the vehicle identity can be identified in the manner of the above embodiment before each weighing.

[0103] Step S202, determining whether the completed conveying volume is greater than or equal to the target conveying volume;

[0104] If the completed conveying volume is greater than or equal to the target conveying volume, step S203 is executed; if the completed conveying volume is less than the target conveying volume, step S20a is executed.

[0105] Step S203, controlling the first gate to close the passage between the entrance area and the weighing area of ​​the weighing device.

[0106] If the completed delivery volume is greater than or equal to the target delivery volume, it indicates that the preset goods do not need to be transported any more. Based on this, the first gate is used to close the passageway between the entrance area and the weighing area. On the one hand, it can prevent the transportation volume of the preset goods from exceeding the planned volume. On the other hand, the closing of the first gate can be used to remind the drivers of the vehicles in the entrance area that they do not need to transport goods any more, so that they can drive the vehicles away from the entrance area as soon as possible to avoid being stranded, so as to effectively improve the logistics efficiency. When the completed delivery volume is less than the target delivery volume, it indicates that the preset goods still need to be transported. At this time, the first gate is used to open the passageway between the entrance area and the weighing area to ensure that the transportation of the preset goods can meet the scheduled plan requirements.

[0107] Wherein, when there are more than one type of preset goods corresponding to the identification information of the vehicle in the current entrance area, step S203 is executed when the delivered quantity of each type of preset goods corresponding to the identification information of the vehicle is greater than or equal to the target delivered quantity; if there is a type of preset goods corresponding to the vehicle identification information with the delivered quantity less than the target delivered quantity, step S20a is executed.

[0108] Further, in this embodiment, before the step of controlling the first gate to open the passage opening between the entrance area and the weighing area of the weighing device, it further includes: if the delivered quantity is less than the target delivered quantity, output a first prompt message. And / or, before the step of controlling the first gate to close the passage opening between the entrance area and the weighing area of the weighing device, it further includes: if the delivered quantity is greater than or equal to the target delivered quantity, output a second prompt message.

[0109] The first prompt message and the second prompt message here can be set in forms such as lights, sounds, displays, etc. according to actual needs. Specifically, the first prompt message and the second prompt message are two prompt messages with different prompt contents, so that the vehicle occupants can quickly know whether their vehicle is allowed to enter the weighing area based on the prompt message. In addition, when the image does not contain the preset vehicle identification information corresponding to the preset goods, before controlling the first gate to close the passage opening between the entrance area and the weighing area of the weighing device, a third prompt message can be output, and the third prompt message has different prompt contents from the second prompt message, so that the vehicle occupants can clearly know the reason why their vehicle is not allowed to enter the weighing area based on the difference between the two prompt messages.

[0110] For example, in this embodiment, the prompt message is output through a signal lamp, the first prompt message is a green light; the second prompt message is a yellow light; the third prompt message is a red light. Based on this, through the change of the signal lamp color, the vehicle occupants can intuitively and clearly know the status of the vehicle identity verification, the status of the preset goods to be transported by the vehicle, etc., and quickly operate their vehicle based on the known information, effectively improving the logistics efficiency.

[0111] Further, based on any of the above embodiments, another embodiment of the vehicle weighing method of the present application is proposed. In this embodiment, referring to Figure 7 , before the step S30, it further includes:

[0112] Step S01, obtaining the vehicle detection information of the weighing area;

[0113] Obtain the detection data of the detection device set on the weighing area as the vehicle detection information here. Specifically, the detection device can be set at the edge of the weighing area, above the weighing area, etc. The detection range of the detection device can cover the edge of the weighing area or the entire weighing area, etc.

[0114] Step S02, determine the target area where the vehicle is located according to the vehicle detection information;

[0115] Step S03, determine whether the target area is entirely within the weighing area;

[0116] If the target area is entirely within the weighing area, then execute step S04; if the target area is not entirely within the weighing area (such as partially within the weighing area or outside the weighing area), then execute step S05.

[0117] Step S04, determine that the vehicle has reached the weighing area;

[0118] Step S05, stop obtaining the detection data of the weighing device.

[0119] For example, when the detection range of the detection device covers the edge of the weighing area, such as an infrared pair device set at the edge, after the passage opening between the entrance area and the weighing area is opened, when the detection device first detects that there is a vehicle at the edge of the weighing area, it can be considered that the vehicle starts to enter the weighing area; after first detecting that there is a vehicle at the edge of the weighing area, when detecting that the vehicle is at the edge of the weighing area again, it can be considered that the vehicle is in the process of entering the weighing area and has not completely fallen into the weighing area, and at this time, the vehicle is not weighed; then, when it is detected that there is no vehicle at the edge of the weighing area, it can be considered that the vehicle is entirely within the weighing area, and at this time, the detection data of the weighing device can be obtained to get the weight of the vehicle on the current weighing area.

[0120] Another example is that when the detection range of the detection device at least partially covers the entire weighing area, such as multiple groups of infrared pair devices or image acquisition devices whose detection ranges cover the weighing area, when the area of the vehicle detected by the detection device within the weighing area is less than the set area, it can be considered that the vehicle is not entirely within the weighing area, and at this time, the vehicle is not weighed; when the area of the vehicle detected by the detection device within the weighing area is greater than or equal to the set area, it can be considered that the vehicle is entirely within the weighing area, and at this time, the detection data of the weighing device can be obtained to get the weight of the vehicle on the current weighing area.

[0121] In this embodiment, ensuring that the vehicle completely falls into the weighing area before measuring the weight of the vehicle can ensure the accuracy of the obtained weight test result.

[0122] Further, based on any of the above embodiments, another embodiment of the vehicle weighing method of the present application is proposed. In this embodiment, referring to Figure 8 , after the step S30, the method further includes:

[0123] Step S40, identifying the type of the weight information;

[0124] The type here can be input manually or obtained by comparing the weight information with a set weight or a previously stored weight.

[0125] Specifically, in this embodiment, obtain the weight associated with the preset vehicle identification information of the vehicle within a target time period; the target time period is a set of moments earlier than the current moment and with a time interval from the current moment less than or equal to a set duration; if the weight information is greater than the stored weight, determine that the type is the weight information when the vehicle is loaded with goods; if the weight information is less than the stored weight, determine that the type is the weight information when the vehicle is unloaded. Specifically, after each weighing of the vehicle corresponding to the preset vehicle identification information, the obtained weight is associated and stored with the preset vehicle identification information. The target time period can be set according to the actual time required for loading goods, such as 15 minutes, half an hour, one hour, etc. Compare the weight associated with the preset vehicle identification information within the target time period with the current weight information, and the setting can also calculate the deviation between the two weights. When the current weight information is greater than the stored weight and the deviation is greater than the set threshold, it can be considered that the current vehicle is loaded with goods, and the current weight information type is the weight information when the vehicle is loaded with goods; when the current weight information is less than the stored weight and the deviation is greater than the set threshold, it can be considered that the current vehicle is unloaded, and the current new weight type is the weight information when the vehicle is not loaded with goods.

[0126] In addition, the type of the weight information can also be identified based on the vehicle image in the weighing area captured currently. When the vehicle image contains a goods image, it can be considered that the current weight information type is the weight information when the vehicle is loaded with goods; when the vehicle image does not contain a goods image, it is considered that the current weight information type is the weight information when the vehicle is unloaded.

[0127] Step S50, if the type is the weight information when the vehicle is unloaded, associate and store the weight information and the preset vehicle identification information;

[0128] The associated and stored weight information can be used for subsequent calculation of the weight of the goods loaded on the vehicle.

[0129] Step S60, if the type is the weight information when the vehicle is loaded with goods, obtain the price of the goods currently loaded on the vehicle;

[0130] The price of the goods can be pre-stored by the system, manually input, or automatically identified based on the actual goods-hauling situation of the vehicle.

[0131] Specifically, in this embodiment, the unladen weight corresponding to the vehicle is obtained, and the unit price information of the preset goods is obtained; the goods weight corresponding to the goods is determined according to the weight information and the unladen weight; the price is determined according to the goods weight and the unit price information. Here, the unladen weight can specifically be the weight associated and stored with the preset vehicle identification information of the vehicle within a preset time period, and the preset time period is a set of moments earlier than the current moment and with a time interval from the current moment less than or equal to the set duration. In addition, in other embodiments, the unladen weight can be obtained from the vehicle net weight information pre-bound and stored with the preset vehicle identification information. The unit price information specifically refers to the price of the preset goods per unit weight. Multiplying the unit price information by the goods weight can obtain the total price of the goods loaded on the current vehicle.

[0132] Step S70, perform a goods settlement operation according to the price, and the goods settlement operation is an operation of deducting the amount corresponding to the price from the account bound with the preset vehicle identification information.

[0133] Specifically, the account here is specifically the account of the goods recipient.

[0134] In this embodiment, through the above method, automatic settlement can be achieved after the vehicle is loaded with goods and weighed, eliminating the need for manual operation in the settlement process and further improving the material efficiency.

[0135] Furthermore, in this embodiment, during the process of determining the weight information of the vehicle according to the detection data of the weighing device, control the second barrier gate to close the passage opening between the exit area corresponding to the weighing device and the weighing area;

[0136] After the step of associating and storing the weight information and the preset vehicle identification information, or after the step of performing a goods settlement operation according to the price, further include:

[0137] Control the second barrier gate to open the passage opening between the exit area corresponding to the weighing device and the weighing area.

[0138] In this way, it is ensured that the vehicle is allowed to leave the weighing area only after the weighing device obtains an accurate weighing result or after the settlement is completed, which can ensure the accuracy of weighing and settlement, and can also prevent un-settled vehicles from leaving the weighing area, ensuring the timeliness of settlement.

[0139] In addition, an embodiment of the present invention further provides a computer-readable storage medium, on which a vehicle weighing program is stored. When the vehicle weighing program is executed by a processor, the relevant steps of any one of the above vehicle weighing methods are implemented.
