[0024] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0025] Figure 1is a flow chart of a method for monitoring vehicle in and out of a factory based on a digital cement pallet provided in an embodiment of the present application, such as Figure 1 As shown, the method includes the following steps S101 to S104.

[0026] Step S101, when the vehicle is located in the factory weighing area, identifying the actual weight of the vehicle through the scale in the factory weighing area; Step S102, identifying the digital cement pallets loaded on the vehicle and the weight of cement carried by each digital cement pallet through an RFID reader in the in-and-out weighing area, wherein the digital cement pallet is used to carry cement and an RFID chip is embedded in the digital cement pallet; Step S103, determining the estimated weight of the vehicle based on the empty weight of the vehicle, the empty weight of the digital cement tray, and the weight of cement carried by each digital cement tray; Step S104, monitoring the carrying status of the vehicle by comparing the actual weight of the vehicle with the estimated weight.

[0027] Digital cement pallet: Each cement pallet is embedded with an RFID chip that can store basic information about the pallet, including the pallet's empty weight, carrying capacity, and its unique identification code. This digital pallet is not only easy to manage, but also enables accurate tracking of cement loading conditions.

[0028] In- and out-of-factory weighing area: A high-precision weighing scale is set up in the weighing area to measure the actual weight of the vehicle in real time. When a vehicle enters the weighing area, the weighing scale automatically records its weight data.

[0029] RFID reader: Equipped with an RFID reader in the weighing area, it can automatically identify the digital cement pallets loaded by the vehicle. By reading the RFID chip in the pallet, the system can obtain relevant information about each pallet, including the weight of cement it carries.

[0030] Workflow: (1) Vehicle weighing upon entry: When a cement transport vehicle enters the weighing area upon entry, the scale automatically identifies and records the actual weight of the vehicle. (2) Pallet identification and weight acquisition: The RFID reader scans all digital cement pallets on the vehicle to obtain the empty weight of each pallet and the weight of the cement it carries. The system aggregates this data and calculates the total weight of all pallets. (3) Estimated weight calculation: The system calculates the estimated weight of the vehicle based on the empty weight of the vehicle, the empty weight of the digital cement pallet, and the weight of the cement carried by each pallet. (4) Transport status monitoring: Finally, the system compares the actual weight of the vehicle with the estimated weight. If the two match, it means the vehicle is in normal condition; if there is a significant difference, the system will sound an alarm and prompt relevant personnel to conduct further inspections. This process can effectively prevent overloading, underloading and other problems, and ensure the safety and compliance of transportation.

[0031] Advantages of the monitoring method provided by this application: (1) Real-time monitoring: Through automated equipment, real-time information on vehicle entry and exit can be obtained, reducing manual intervention and improving monitoring efficiency. (2) Data accuracy: The combination of RFID technology and high-precision weighing equipment ensures data accuracy and reduces the possibility of human error. (3) Intelligent early warning: The system can automatically identify abnormal situations and issue alarms in a timely manner, facilitating rapid response and processing. (4) Management optimization: Through data analysis, enterprises can better grasp the dynamics of cement transportation and optimize production scheduling and inventory management.

[0032] Therefore, the monitoring method provided in the present application can efficiently monitor the inbound and outbound transportation of cement shipping vehicles by combining digital cement pallets and floor scale weighing.

[0033] In a possible implementation, the above-mentioned identification of the digital cement pallets loaded on the vehicle and the weight of the cement carried by each digital cement pallet through the RFID reader in the inbound and outbound weighing area includes: The RFID chip in the digital cement pallet loaded on the vehicle is read by an RFID reader to obtain the unique identification information corresponding to each digital cement pallet; The unique identification information corresponding to each digital cement pallet is input into the target database, and the weight of cement carried by each digital cement pallet output by the target database is obtained. The target database is used to query the weight of cement carried by the digital cement pallet based on the unique identification information corresponding to the digital cement pallet.

[0034] Specifically, the information stored in the target database usually includes the unique identification of the pallet, the empty weight, the weight of the cement carried, the production date, the batch number, the transportation status, etc. This information provides the basis for subsequent query and analysis. The unique identification information of each digitized cement pallet read will be transmitted to the target database in real time. The target database retrieves relevant records based on the identification information and returns the weight of the cement carried by the pallet.

[0035] By reading the unique identification information in the digital cement pallet through the RFID reader and interacting with the target database, the company can achieve accurate management and monitoring of the cement pallet. This process not only improves the efficiency and accuracy of data collection, but also provides a data basis for subsequent transportation management, inventory control and decision support.

[0036] In a possible implementation, the method further includes: When loading cement onto the digital cement pallet, the weight of the cement carried by the digital cement pallet is determined based on the number of cement bags loaded and the weight of each bag of cement, and the weight information is synchronized to the target database; In the case of unloading cement from the digital cement pallet, if it is confirmed that the cement unloading is completed, the weight of the cement carried by the digital cement pallet is determined to be 0, and the weight information is synchronized to the target database.

[0037] Specifically, when cement is loaded onto a digital cement pallet, the total weight carried by the pallet can be determined based on the number of cement bags loaded and the weight of each bag of cement. For example, if 20 bags of cement are loaded, each weighing 50 kg, the weight of cement carried by the pallet is 1,000 kg. Once the weight of cement carried by the digital cement pallet is determined, the system will synchronize this information to the target database. The synchronized data typically includes: unique identification information of the pallet, weight of cement carried by the pallet, loading time, and operator information (optional).

[0038] When unloading cement from the digital cement pallet, the operator needs to confirm that the unloading of cement has been completed. This is usually achieved through visual inspection or the use of sensors to ensure that all cement bags have been successfully unloaded. Once the cement unloading is confirmed to be complete, the system will automatically update the cement weight carried by the digital cement pallet to 0. After unloading is completed, the system will synchronize the pallet's load weight information to the target database and update the pallet's status to "empty". The synchronized data usually includes: the unique identification information of the pallet, the updated load weight (0 kg), the unloading time and the operator information (optional).

[0039] In a possible implementation, the above-mentioned determining the estimated weight of the vehicle based on the empty weight of the vehicle, the empty weight of the digital cement tray, and the weight of cement carried by each digital cement tray includes determining the estimated weight of the vehicle by the following formula; ; in, Indicates the estimated weight, Indicates the unladen weight of the vehicle. Indicates the empty weight of the digital cement pallet, Indicates the number of digitized cement pallets loaded on the vehicle, Indicates The weight of cement carried by a digital cement pallet.

[0040] In a possible implementation, the above-mentioned monitoring of the vehicle's carrying status by comparing the actual weight of the vehicle with the estimated weight includes: Determine the absolute value of the difference between the actual weight and the estimated weight; Determine whether the absolute value is less than a preset threshold; If the absolute value is less than or equal to the preset threshold, the vehicle's carrying state is determined to be a normal carrying state; if the absolute value is greater than the preset threshold, the vehicle's carrying state is determined to be an abnormal carrying state.

[0041] In a possible implementation, after determining that the carrying state of the vehicle is an abnormal carrying state, it also includes: issuing an audible and visual prompt through an audible and visual alarm module in the inbound and outbound weighing area.

[0042] In a possible implementation, the inbound and outbound weighing area includes: an inbound weighing sub-area and an outbound weighing sub-area; A metal shielding net is arranged between the incoming weighing sub-area and the outgoing weighing sub-area; The in-plant weighing sub-area is equipped with a first RFID reader and a first weighbridge. The first RFID reader is used to identify the digital cement pallet loaded by the in-plant vehicle, and the first weighbridge is used to identify the actual weight of the in-plant vehicle. The factory weighing sub-area is equipped with a second RFID reader and a second floor scale. The second RFID reader is used to identify the digitized cement pallet loaded on the factory vehicle, and the second floor scale is used to identify the actual weight of the factory vehicle.

[0043] In the intelligent cement consignment monitoring solution, the design of the inbound and outbound weighing area is crucial.

This area is designed to ensure that the vehicle's load status is accurately recorded before entering the plant.

[0044] (1-2) Equipment configuration: First RFID reader: This device is used to identify the digital cement pallets loaded by vehicles entering the factory. When the vehicle enters, the RFID reader automatically scans the RFID chip on the pallet to obtain relevant information about the pallet, including the pallet's empty weight, carrying capacity and its unique identification code. This process enables real-time tracking of each pallet to ensure data accuracy.

[0045] First scale: This high-precision scale is used to measure the actual weight of vehicles entering the plant. When a vehicle enters the weighing area, the scale automatically records the total weight of the vehicle, including the weight of the vehicle itself and the weight of the cement loaded.

[0046] (1-3) Data processing: The equipment in the factory weighing sub-area transmits the collected data to the central control system. The system calculates the estimated weight of the vehicle based on the data from the RFID reader and the scale, and compares it with the actual weight to ensure that the carrying status of the vehicle entering the factory meets the standards.

[0047] (2) Factory weighing sub-area; (2-1) Function and layout: The outbound weighing sub-area is used to monitor the weighing and pallet identification of cement transport vehicles when they leave the factory. This area is designed to ensure that when the vehicle leaves the factory, its loading status can be accurately recorded for subsequent inventory management and transportation scheduling.

[0048] (2-2) Equipment configuration: Second RFID reader: This device is used to identify the digitized cement pallets loaded by the outgoing vehicles. Similar to the inbound area, when the vehicle enters the outbound weighing sub-area, the RFID reader will automatically scan the pallet and obtain relevant information to ensure that the loading status of each pallet is accurately recorded.

[0049] Second scale: This high-precision scale is used to measure the actual weight of the vehicle leaving the factory. When the vehicle leaves the weighing area, the scale automatically records the total weight of the vehicle, including the weight of the vehicle itself and the weight of the cement loaded.

[0050] (2-3) Data processing: The equipment in the factory weighing sub-area will also transmit the collected data to the central control system. The system will calculate the estimated weight of the vehicle based on the data from the RFID reader and the scale, and compare it with the actual weight to ensure that the carrying status of the vehicle meets the standards when leaving the factory.

[0051] The role of metal shielding net Isolation and protection: The metal shielding net configured between the incoming weighing sub-area and the outgoing weighing sub-area can effectively isolate the two, prevent data interference and confusion, and ensure the data independence of each area.

[0052] Security: The metal shielding net can also prevent external interference, protect the normal operation of the equipment, and ensure the stability and reliability of the monitoring system.

[0053] (3) Overall monitoring process; (3-1) Vehicles entering the factory: When the vehicle enters the weighing sub-area, the first RFID reader identifies the pallet information, the first scale records the actual weight, and the data is transmitted to the central control system for processing.

[0054] (3-2) Vehicle leaving the factory: The vehicle enters the factory weighing sub-area, the second RFID reader identifies the pallet information, the second scale records the actual weight, and the data is transmitted to the central control system for processing.

[0055] (3-3) Data analysis and early warning: The central control system conducts real-time analysis of vehicle data entering and leaving the factory to ensure the compliance of the transportation status, and promptly issues alarms when abnormalities are found to facilitate processing by relevant personnel.

[0056] Through this refined monitoring solution, companies can achieve efficient management of cement transport vehicles, improve the transparency and safety of the transportation process, optimize resource allocation, and reduce operational risks.
