Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0077] In addition, the term "and / or" herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. In addition, the character " / " herein, unless otherwise specified, generally represents an "or" relationship between the associated objects before and after it.

[0078] The embodiments of the present application disclose a full-automatic intelligent metering management system. Referring to Figure 1 The full-automatic intelligent metering management system comprises a scale 1 and a metering terminal 2, and the scale 1 and the metering terminal 2 are both arranged at a weighing site.

[0079] The metering terminal 2 comprises a switch 21, the scale 1 is connected with the switch 21, and the switch 21 can receive the vehicle weight weighed by the scale 1. The switch 21 is connected with an electronic device 3 through an optical fiber, and the electronic device 3 is respectively connected with a driver client 4 and a manufacturer client 5. The driver of the driving vehicle can log in the driver client 4, submit the weighing request information to the electronic device 3 through the driver client 4, and input the user personal information and the license plate information and the like. The manufacturer client 5 is arranged in a control room, the control room can be far away from the site, the manufacturer client 5 can obtain all the data uploaded to the electronic device 3, can uniformly manage and check the running conditions of each device, and can send an instruction according to the data, the electronic device 3 sends the instruction to the switch 21, the switch 21 responds, and then the electronic device 3 also communicates with the switch 21.

[0080] The switch 21 is connected with the camera 22 through a network cable. In one possible implementation, the camera 22 is arranged on the metering terminal 2 which is arranged on the front side of the weighbridge 1. Before the vehicle drives into the weighbridge 1, the camera 22 captures the vehicle to obtain a vehicle image, and then sends the vehicle image to the switch 21, and then the electronic device 3 analyzes the vehicle image to obtain a license plate image and recognize license plate information. When the license plate information is consistent with the license plate information pre-registered by the driver, the vehicle is allowed to drive into the weighbridge 1.

[0081] The camera 22 simultaneously sends the situation of the weighing site to the electronic device 3 in real time through the switch 21, so that the manufacturer client 5 in the control room can view the site in real time.

[0082] In another possible implementation, the camera 22 is arranged on the front side and the rear side of the weighbridge 1. The camera 22 on the front side captures a front image of the vehicle, and the camera 22 on the rear side captures a rear image of the vehicle. Therefore, the electronic device 3 can obtain front license plate information and rear license plate information of the vehicle according to the front image and the rear image of the vehicle respectively. When the two license plate information are consistent, it can be determined that there is only one vehicle on the weighbridge 1. If the front and rear license plate information are inconsistent, there may be multiple vehicles on the weighbridge 1.

[0083] A red-green light system 6 is arranged in front of the weighbridge 1. The switch 21 is connected with a PLC controller 23, and the red-green light system is connected with the PLC controller 23. The switch 21 receives a first control instruction sent by the electronic device 3, and communicates with the driver by controlling the on-off of the red-green light system 6. For example, when the green light is on, the driver can drive the vehicle to the scale for weighing. When the red light is on, the driver stops driving and turns off the engine. At this time, the weighbridge 1 weighs, and the switch 21 sends the weighing weight to the electronic device 3. When the green light is on again, the driver drives the vehicle to the scale for weighing.

[0084] The switch 21 is also connected with a sound column 24. The sound column 24 can play the set voice information. For example, when the green light is on, the sound column 24 automatically plays the broadcast information guiding the vehicle to the scale for weighing. When the red light is on, the sound column 24 automatically plays the broadcast information guiding the vehicle to the scale for weighing. The staff in the control room can also set a microphone 7 which is connected with the manufacturer client 5. Therefore, the sound column 24 can play the communication voice between the staff and the driver through the microphone 7, and timely give manual prompt when the driver does not move according to the red-green light indication.

[0085] Further, in order to monitor the position of the vehicle, the application also includes a positioning device 8. The positioning device 8 can be a radar device, a GPS locator, a Beidou satellite navigation system locator or a positioning device based on a mobile communication network (such as GSM, CDMA, LTE, etc.).

[0086] Reference Figure 1In the embodiment 1, if the positioning device 8 is a radar device, the radar device is arranged around the weighbridge 1 and connected with the PLC controller, so as to determine the position of the vehicle on the weighbridge 1, and the electronic device 3 can record the position of the vehicle when stopping, and further guide the same vehicle to stop at the same position when weighing for the first time and weighing for the second time, and more accurately calculate the tare weight and gross weight of the vehicle.

[0087] With reference to Figure 2 In the embodiment 2, if the positioning device 8 is a GPS locator, a Beidou satellite navigation system locator or a positioning device based on a mobile communication network, the positioning device 8 is connected with the vehicle-mounted terminal, the vehicle-mounted terminal obtains the position information of the vehicle and communicates with the electronic device 3, and the electronic device 3 obtains the position of the vehicle.

[0088] With reference to Figure 1 When the weighing is completed, the electronic device 3 obtains the weighing result and generates an electronic weigh ticket, and can send the electronic weigh ticket to the driver client 4, so that the driver can view the electronic weigh ticket online.

[0089] Further, the PLC controller 23 is further connected with the access control system 9, the access control system 9 is arranged at the factory outlet, the electronic device 3 checks the relevant information and sends a second control instruction to the access control system 9. When the vehicle weighing is completed and has a corresponding electronic weigh ticket, the second control instruction is to open the access control system 9 when the vehicle leaves the factory; otherwise, the second control instruction is not to open the access control system 9 when the vehicle leaves the factory.

[0090] Further, the switch 21 is further connected with the card reader 25, when a driver often weighs the vehicle, the driver can swipe the identity information identification card 10 on the card reader 25, the identity information identification card 10 can be an IC card or an identity card. The driver information and the license plate information are stored in the IC card, and the driver information is stored in the identity card. If the driver swipes the IC card on the card reader 25, the electronic device 3 obtains the driver information and the license plate information, and then generates the weighing request information and starts the weighing process; if the driver swipes the identity card on the card reader 25, the electronic device obtains the driver information, and then searches whether the license plate information corresponding to the driver information is stored, if yes, the weighing request information is automatically generated; if not, the driver is prompted to contact the staff to input the license plate information.

[0091] The switch 21 is further connected with the display device 26, the display device 26 can display the weighing information and the electronic weigh ticket.

[0092] Therefore, the computer program for controlling the weighing is arranged in the electronic device 3, and the weighing site only includes the camera 22, the traffic light system 6, the positioning device 8 and the like, and the input and output signals are received and sent through the switch 21, so that the remote monitoring and operation of the electronic device 3 are realized, and the stable PLC controller 23 is used to control the device, so that the use of the on-site device is greatly reduced and the device is not easy to be damaged. On the other hand, the PLC controller 23 has strong heat resistance, and almost no heat dissipation problem exists in the use process, and the risk of death is reduced, so that the hardware cost and the maintenance cost are saved, the stability of the metering terminal is enhanced, and the failure rate is reduced.

[0093] In addition, the electronic device 3 supports separate writing of links, and a staff member can customize a metering program by configuring link combinations, so that the convenience of operation and upgrading is improved. In addition, when the metering program needs to be updated, the application can realize online unified deployment of corresponding programs on the electronic device 3, the driver client 4 and the manufacturer client 5, without the need for on-site updating, so that the updating cost is greatly reduced.

[0094] Further, the PLC controller 23, the camera 22, the sound column 24, the card reader 25 and the display device 26 in the embodiment of the application all adopt network protocol devices, and communicate with the switch 21 through TCP, HTTP and the like, so that the devices are not easy to be affected by the surrounding environment.

[0095] In another possible implementation, the weighing site is generally arranged outdoors, and the outdoor high temperature and the like easily affect the service life of the device. Therefore, the metering terminal 2 further includes a shell 27, and the devices connected with the switch 21 and the switch 21 are arranged in the shell 27, and only the camera 22 and the display device 26 are exposed on the surface of the shell 27. Therefore, the shell 27 protects various devices therein, centrally manages the devices, plays a role in preventing rain and dust, and can also weaken the adverse effects of outdoor high temperature on operation.

[0096] The shell 27 can be preferably an explosion-proof shell. When the full-automatic intelligent metering management system is arranged in a dangerous area, the explosion-proof shell can improve the explosion-proof performance of the metering terminal, so that the metering terminal is applicable to use in the dangerous area.

[0097] The application provides a full-automatic intelligent metering management system. A driver establishes a weighing request information through a driver client 4. A camera 22 obtains vehicle related information and monitors a scene. A traffic light system 6 and a sound column 24 guide a vehicle to automatically go to a scale for weighing and leave the scale. A positioning device 8 monitors a position of the vehicle. An exchange 21 receives output signals of the traffic light system 6, the sound column 24 and an access control system 9, and transmits the signals to an electronic device 3. After the weighing request information is audited, the electronic device 3 automatically guides the driver to weigh according to a set program, and sends an electronic scale ticket to the driver client 4. A manufacturer client 5 is connected with the electronic device 3, so that the weighing scene can be remotely monitored, the weighing process can be remotely communicated and processed with the driver, the communication process between the driver and the manufacturer staff is reduced, the automatic weighing task is completed, the time required in the weighing process is shortened, and the transportation efficiency is improved.

[0098] The application also provides a full-automatic intelligent metering management method applied to the full-automatic intelligent metering management system and executed by an electronic device. Figure 3 The electronic device can be a server or a terminal device.

[0099] Step S101: information inputting: obtaining a weighing request information, the weighing request information including user information and license plate information, auditing the weighing request information and saving the weighing request information.

[0100] Specifically, the driver can log in the driver client to create an account, save a contact number and a login password, and perform real-name authentication in the driver client. After the account is created, the driver can register a vehicle model and a license plate and the like in the account, support adding a weighing request information and inquiring a historical electronic scale ticket, and communicate with the electronic device to receive prompt information and the like sent by the electronic device.

[0101] Before the driver needs to weigh, the driver logs in the driver client and uploads the weighing request information on the driver client. For example, a one-key application button can be displayed in the software interface of the driver client, and the driver clicks the one-key application button, and the driver client automatically generates the weighing request information according to the pre-filled user information and license plate information. The weighing request information includes user information and license plate information, the user information is the personal information of the driver, and the license plate information is the license plate information of the vehicle to be weighed. The driver client sends the weighing request information to the electronic device, and the electronic device audits the weighing request information, the audit content includes whether the user information is complete and consistent with the information in the historical record, saves when the audit is passed, and rejects when the audit is not passed.

[0102] Step S102: identity recognition: obtaining a license plate image, identifying license plate information based on the license plate image, and determining whether the license plate information is consistent with the license plate information in the weighing request information; if consistent, the vehicle is allowed to proceed; otherwise, an alarm information is generated.

[0103] Specifically, before the vehicle enters the weighbridge, the camera continuously captures the entrance of the weighbridge to obtain a plurality of continuous images, and uploads the images to the electronic device. The electronic device inputs the images into a license plate recognition model trained by a machine learning method in advance, and when a license plate is identified in the image, the corresponding image is a license plate image. Further, the license plate information in the license plate image is identified and compared with the plurality of received weighing request information, and when the identified license plate information is consistent with the license plate information in any weighing request information, the vehicle is allowed to proceed; if no consistent information is found, an alarm information is generated.

[0104] After generating the alarm information, the electronic device can make the sound column automatically broadcast the alarm information to prompt the driver to submit the weighing request information, or swipe the identity information identification card on the card reader.

[0105] Step S103: weighing: guiding the vehicle to weigh on the scale and guiding the vehicle to weigh off the scale after the weighing is completed, and determining the corrected weighing record, the weighing record including the weighing time and the weighing weight.

[0106] Specifically, when the electronic device checks that the license plate information is consistent, the red light system and the sound column are used to guide the vehicle to weigh on the scale, for example, the green light of the red light system is on, and the sound column plays the broadcast information guiding the vehicle to weigh on the scale.

[0107] In fact, there are many factors that can cause weighing errors when the vehicle is weighed, such as the error of the weighbridge itself, the shaking of the vehicle, the position of the vehicle when weighing the tare weight and the gross weight, and the inconsistency of the personnel in the vehicle.

[0108] Step S103 includes (steps S11-S19) when guiding the vehicle to weigh on the scale and guiding the vehicle to weigh off the scale after the weighing is completed, and determining the corrected weighing record.

[0109] Step S11: automatically zeroing the weighbridge before weighing the vehicle.

[0110] Specifically, when the electronic device verifies that the license plate information is consistent, the weighbridge is automatically zeroed, thereby reducing the error of the weighbridge itself before weighing.

[0111] In another possible implementation, if the error of the automatically zeroed weighbridge is greater than the preset value multiple times, the weighbridge may have an abnormality, and further investigation of the abnormality is required. Therefore, the following steps (steps Sa-Se) are included:

[0112] Step Sa: obtaining the input voltage of the weighbridge instrument, the output signal value of the weighbridge sensor, the radar detection information of the surface of the weighbridge, and the historical maintenance record each time the weighbridge is automatically zeroed.

[0113] Step Sb: generating a maintenance prompt information if the maintenance frequency within a preset time is determined to be lower than a preset value according to the historical maintenance record.

[0114] Specifically, when the maintenance frequency of the weighbridge is too low, the maintenance prompt information is generated to prompt the staff to perform timely maintenance, thereby preventing faults in advance and improving the weighing accuracy.

[0115] Step Sc: determining a voltage range according to the multiple input voltages, comparing the voltage range with a preset range, and determining that the power voltage is abnormal when the voltage range exceeds a preset percentage of the preset range.

[0116] Specifically, the input voltage of the weighbridge also has a slight fluctuation during use, and the voltage range can be determined according to the multiple input voltages. When the voltage range is within the preset range, it can be determined that the power voltage of the weighbridge is temporarily normal. When the voltage range exceeds the preset percentage of the preset range, it can be determined that the voltage range has a large deviation, and the power voltage is determined to be abnormal.

[0117] Step Sd: when the output signal value is greater than a preset signal value, determining a signal stability value according to the multiple output signal values, and determining that the weighbridge sensor is abnormal when the signal stability value is greater than a preset stability value.

[0118] Specifically, when the output signal value is greater than the preset signal value, the difference values of the multiple output signal values that exceed the preset signal value are calculated, and the ratio of the total value of the difference values to the number of output signals is calculated. The ratio is determined as the signal stability value. When the signal stability value is greater than the preset stability value, it can be determined that the number of times that the output signal of the weighbridge sensor exceeds the preset signal value is too large and the deviation is too large, and thus the weighbridge sensor is determined to be abnormal.

[0119] Step Se: If the radar detection information exists, when there are multiple radar detection information and the standard radar detection information of the standard state of the weighbridge is inconsistent, it is determined that the foundation of the weighbridge is abnormal.

[0120] Specifically, if the positioning device in the system is a radar device, the electronic device can obtain radar detection information, and the radar detection information can also detect the position information of the foundation of the weighbridge. The electronic device sets the standard radar detection information in the standard state of the weighbridge, i.e., the position of the foundation of the weighbridge in the standard state, and when the detected position of the foundation of the weighbridge is inconsistent with the position of the foundation of the weighbridge in the standard state, it is determined that the foundation of the weighbridge is abnormal.

[0121] If the positioning device in the system is a GPS locator, a Beidou satellite navigation system locator, or a positioning device based on a mobile communication network, the positioning device cannot detect the position information of the foundation of the weighbridge, and therefore the electronic device cannot obtain radar detection information, i.e., if the radar detection information does not exist, step Se is not performed at this time.

[0122] Step S12: Determine whether there is a historical electronic weighbridge ticket corresponding to the user information.

[0123] Specifically, when the driver submits the weighing request information, the electronic device queries whether there is a historical electronic weighbridge ticket of the current user according to the user information, and obtains the historical electronic weighbridge ticket if there is. If the historical electronic weighbridge ticket exists, it is determined that the vehicle is not weighed for the first time; if the historical electronic weighbridge ticket does not exist, it is determined that the vehicle is weighed for the first time.

[0124] If not, step S13 is performed: it is determined that the vehicle is weighed for the first time, the vehicle is guided to the scale, the vehicle position information when the vehicle stops is obtained, and the driver's room image is analyzed to determine the personnel information on the vehicle.

[0125] Specifically, since the vehicle is in different positions of the weighbridge, the weighing result will also be slightly different. When the vehicle is weighed for the first time, in order to ensure the consistency of the tare weight and the gross weight of the vehicle, the vehicle position information when the vehicle stops after being weighed is needed to be remembered. Even if the vehicle does not use the same weighbridge for two times of weighing, the vehicle can also be stopped at the same position.

[0126] The positioning device can monitor the position of the vehicle on the weighbridge in real time, and the electronic device guides the vehicle to the scale through the traffic light system. When the vehicle reaches the preset position, the red light can be turned on to guide the vehicle to stop. If the vehicle does not stop accurately at the preset position, as long as the vehicle is located on the weighbridge at the head and tail, the current position information of the vehicle can also be saved.

[0127] Further, in order to improve the accuracy of weighing, it is required that the vehicle is empty or the same person is in the cab when the vehicle is weighed. Therefore, after the vehicle stops, the electronic device makes the sound column play a voice to prompt the driver to get off and stand outside the platform, and the camera can take pictures of the vehicle cab position. The electronic device obtains the image taken by the camera, inputs the image into the face recognition model trained by the machine learning algorithm in advance, recognizes the face in the cab and saves it as personnel information; if no face information is recognized, the personnel information is empty.

[0128] If yes, step S14 is performed: it is determined that the vehicle is not weighed for the first time, the vehicle position information at the last weighing is guided to stop, the new cab image is obtained again, and it is determined whether the personnel information on the vehicle is consistent with the last weighing through the new cab image.

[0129] Specifically, if the vehicle is not weighed for the first time, in order to keep the weighing position consistent, the electronic device guides the vehicle to the position of the last weighing through the signal of the traffic light system, and the red light is on at the same time. Through the analysis of the personnel information in the cab, it is determined whether it is consistent with the last weighing.

[0130] If yes, step S15 is performed: continue weighing; if no, step S16 is performed: generate prompt information, repeat the step of determining whether the personnel information on the vehicle is consistent with the last weighing until the personnel information on the vehicle is consistent with the last weighing.

[0131] Specifically, if the personnel in the cab is consistent with the last time, there is no one or the same person, the weighing can continue; if not, the prompt information is generated. The prompt information can be played by the sound column to prompt the driver, and the weighing continues until it is consistent.

[0132] Step S17: after the vehicle stops, a plurality of vehicle images are continuously obtained, and it is determined whether the vehicle is in an off state according to the plurality of vehicle images.

[0133] Specifically, when the vehicle is in an off state, the vehicle has no shaking, which can greatly reduce the weighing error. Therefore, the electronic device obtains a plurality of vehicle images taken by the camera, and analyzes the plurality of vehicle images to determine whether the vehicle is in an off state, including (step S1712 to step S178):

[0134] Step S171: determine that the initial shaking value is zero.

[0135] Specifically, the electronic device obtains the shaking value by analyzing the license plate image, and determines whether the vehicle has shaking by the size of the shaking value, so the initial state of the shaking value is zero.

[0136] Step S172: input the vehicle image into a license plate recognition model trained by a pre-applied machine learning method, and determine first position information of the license plate in the vehicle image.

[0137] Specifically, since the license plate has a standard shape for easy recognition and belongs to the common characteristics of each vehicle, the electronic device applies a machine learning algorithm to train a license plate recognition model, inputs the vehicle image into the license plate recognition model, and can output the first position information of the license plate in the vehicle image.

[0138] Step S173: determine the license plate center point and the license plate edge according to the first position information.

[0139] Specifically, the first position information is a set of position points of the entire license plate, and then the electronic device determines the license plate center point and the license plate edge therefrom.

[0140] Step S174: arrange the vehicle images in time sequence.

[0141] Step S175: take the second vehicle image as the current vehicle image.

[0142] Step S176: determine displacement information of the license plate center point and angle information of the same license plate edge between the current vehicle image and the previous vehicle image.

[0143] Step S177: if the displacement information and the angle information are both zero, determine that the shaking value is zero, if the displacement information or the angle information is not zero, determine that the shaking value is one, take the next vehicle image as the current vehicle image, and repeat step S176 until there is no next vehicle image, and obtain the final shaking value.

[0144] Specifically, if the displacement information and the angle information are both zero, it means that in the current vehicle image and the previous vehicle image, the center point and the edge of the license plate are not changed, which can prove that the vehicle does not shake, and the shaking value does not change; if any of the displacement information and the angle information is not zero, it means that the vehicle shakes, and the shaking value is one. Until the comparison of each vehicle image in the sequence is completed, the final shaking value is obtained.

[0145] Step S178: if the shaking value is less than a preset value, determine that the vehicle is in an off state; otherwise, determine that the vehicle is not in an off state.

[0146] Specifically, generally, since the vehicle can still have slight shaking during the buffering after the engine is turned off, the image of the vehicle captured by the camera can include the image of the vehicle after the engine is turned off for a period of time, and therefore the preset value is set in the present application, which can be set as 10% of the number of vehicle images, and the preset value sufficiently considers the shaking value caused by the shaking of the vehicle after the engine is turned off. When the shaking value is less than the preset value, it can be basically determined that the vehicle is in the off state, otherwise, the vehicle is not in the off state.

[0147] If the vehicle is in the off state, step S18 is performed: guiding the vehicle to the scale after the weighing is completed, and determining the corrected weighing record.

[0148] Specifically, if the vehicle is in the off state and the weighbridge has been automatically cleared before weighing, the obtained weighing record can be determined as the corrected weighing record.

[0149] If the vehicle is not in the off state, step S19 is performed: generating warning information, and repeating step S17 until the vehicle is in the off state.

[0150] Specifically, if the vehicle is not turned off, the sound column is prompted to broadcast warning information to prompt the driver to turn off the engine, and the vehicle is continuously monitored until the vehicle is turned off and step S18 is performed.

[0151] Step S104: obtaining a weighing result according to at least two weighing records, and generating an electronic scale sheet according to the weighing result. Including (step S1041 to step S1046):

[0152] Step S1041: determining whether the time difference between the weighing time of the current weighing record and the weighing time of the last weighing record is within a preset range.

[0153] Specifically, when the vehicle needs to be weighed, if it is for loading, the empty vehicle weight is weighed before loading, and the loaded vehicle weight is weighed after loading, so that the loading weight can be obtained; if it is for unloading, the loaded vehicle weight is weighed before unloading, and the remaining weight is weighed after unloading, so that the unloading weight can be obtained. Therefore, the time between the adjacent two weighings is generally the time for loading or unloading, and the time difference between the two weighings can be foreseeable according to the actual situation in the factory. For example, according to the investigation, it is determined that the general loading and unloading time is about 4 hours, and the preset range can be 5 hours. If the time difference is within the preset range, it can be determined that the two weighing records are continuous; if the time difference is not within the preset range, such as 12 hours, the two weighings can not belong to the same batch of goods.

[0154] If yes, step S1042 is performed: determining the difference between the corresponding weighing weights in the two weighing records as the weighing result.

[0155] Otherwise, step S1043 is performed: feedback information is generated and sent to the driver client, the feedback information including whether the weighing result is determined according to the current weighing record and the last weighing record.

[0156] Specifically, when the difference in time is not within the preset range, the possibility of a special situation, such as queuing for unloading or loading for too long, is not excluded, and the electronic device generates feedback information, which respectively displays the weighing time and the weighing weight at the current and last weighing times, and the driver replies to the feedback information on the driver client to determine whether the weighing result is obtained according to the current weighing record and the last weighing record.

[0157] Step S1044: obtaining reply information of the driver client to the feedback information.

[0158] If the reply information is yes, step S1045 is performed: the difference between the corresponding weighing weights in the two weighing records is determined as the weighing result.

[0159] If the reply information is no, step S1046 is performed: the current weighing record is determined as the first weighing record.

[0160] Specifically, if the driver replies yes, the weighing result is calculated, and if the driver replies no, the current weighing is the first weighing.

[0161] Further, after the electronic device obtains the weighing result, an electronic scale ticket is generated and sent to the driver client. The electronic scale ticket can include license plate information, material name, delivery unit, receipt unit, gross weight weighing time and weight, gross weight weighing scale number, tare weight weighing time and weight, tare weight weighing scale number, etc. The driver can view the electronic scale ticket online through the driver client.

[0162] Step S105: identifying release: identifying the license plate information corresponding to the license plate image when the vehicle leaves the factory, and if the license plate information includes the corresponding electronic scale ticket, the vehicle is released.

[0163] Specifically, when the vehicle leaves the factory, the access control system at the factory outlet identifies the license plate information of the vehicle, queries the corresponding electronic scale ticket, and then opens the access control system to release the vehicle.
