[0040] The data interface unit 6 provides data interface services and is the hub for data interaction between various units. It is used to receive and send data between units. By parsing the socket data message, it determines the data source unit and the data receiving unit, and transmits the communication data between units accurately.

[0041] The specific implementation method of the present invention is as follows: 1. Develop a vehicle environmental information verification model in the access control unit 5. The input parameters of the model are the license plate number, license plate color, transport material code, and transport material name, and the output parameters are the clean transportation mark and error code. According to the four parameters received, first use the license plate number and license plate color to search for vehicles in the vehicle environmental information database; then use the transport material code and transport material name to search for materials in the clean transportation control material database. If the vehicle search is successful, the vehicle emission standard in the vehicle environmental information database is compared with the emission standard required for the transport materials in the clean transportation control material database. When the vehicle emission standard is higher than the emission standard required for material transportation, the interface outputs the clean transportation mark as 1 and the error code as 0; when the vehicle emission standard is lower than the emission standard required for material transportation, the interface outputs the clean transportation mark as 0 and the error code as 1. If the vehicle search is unsuccessful, it means that the vehicle has not entered the vehicle environmental information database, and the interface outputs the clean transportation mark as 0 and the error code as 2.

[0042] In order to express the verification logic of the above vehicle environmental information verification interface with a formula, we can define some variables and functions to represent each step. Here, we use a pseudo-code style formula to describe it.

[0043] First, define some variables and functions: licensePlate: license plate number plateColor: license plate color transportCode: transport material code transportName: transport material name emissionStandardVehicle: Vehicle emission standard (retrieved from the vehicle environmental information database) requiredEmissionStandard: The emission standard required for material transportation (retrieved from the clean transportation control material library) isVehicleFound: Whether the vehicle retrieval was successful (Boolean value) cleanTransportFlag: Clean transport flag errorCode: error code Next, define a function to simulate the retrieval operation: searchVehicleInfo(licensePlate, plateColor): retrieves vehicle information based on license plate number and plate color, returning the vehicle emission standard or null (not found).

[0044] searchMaterialInfo(transportCode, transportName): retrieves material information based on the transport material code and name, and returns the emission standards required for material transportation.

[0045] Now, we can build the logic formula: # Retrieve vehicle information isVehicleFound=searchVehicleInfo(licensePlate, plateColor)!=null if isVehicleFound: emissionStandardVehicle=searchVehicleInfo(licensePlate, plateColor) requiredEmissionStandard=searchMaterialInfo(transportCode,transportName) # Compare emission standards if emissionStandardVehicle > requiredEmissionStandard: cleanTransportFlag = 1 errorCode = 0 else: cleanTransportFlag = 0 errorCode = 1 else: cleanTransportFlag = 0 errorCode = 2 # Output results output(cleanTransportFlag, errorCode) 2. When creating a factory entry forecast, the truck entry forecast APP module 106 in the bulk raw material procurement unit 1 sends the license plate number, license plate color, material code, and material name to the access control unit 5 through the data interface unit 6. According to the result returned by the interface, it is judged whether the factory entry forecast meets the requirements of the clean transportation emission standards. If the returned result is 10, it means that the requirements are met, and the vehicle entry forecast can be created normally. The successfully created factory entry forecast is sent to the procurement entry management module 404 of the logistics control unit 4 through the data interface unit 6; if the returned result is 01, it means that the requirements are not met, and the user is reminded that the vehicle does not meet the emission standards and the transport vehicle needs to be replaced; if the returned result is 02, it means that the vehicle data has not been entered into the vehicle environmental protection information database 501, and the user is reminded that the vehicle information needs to be entered into the database first.

[0046] 3. When creating an entry task, the truck entry task management module 206 in the material and spare parts procurement unit 2 sends the license plate number, license plate color, material code, and material name to the access control unit 5 through the data interface unit 6. According to the result returned by the interface, it is judged whether the entry task meets the requirements of the clean transportation emission standards. If the returned result is 10, it means that the requirements are met, and the vehicle entry task can be created normally. The successfully created entry task is sent to the procurement entry management module 404 of the logistics control unit 4 through the data interface unit 6; if the returned result is 01, it means that the requirements are not met, and the user is reminded that the vehicle does not meet the emission standards and the transport vehicle needs to be replaced; if the returned result is 02, it means that the vehicle data has not been entered into the vehicle environmental protection information database 501, and the user is reminded that the vehicle information needs to be entered into the database first.

[0047] 4. When creating a sales vehicle dispatch task, the sales vehicle dispatch management module 304 in the product sales unit 3 sends the license plate number, license plate color, material code, and material name to the access control unit 5 through the data interface unit 6. According to the result returned by the interface, it is judged whether the sales vehicle dispatch task meets the requirements of the clean transportation emission standards. If the returned result is 10, it means that the requirements are met, and the vehicle dispatch task can be created normally. The successfully created vehicle dispatch task is sent to the sales factory management module 405 of the logistics control unit 4 through the data interface unit 6; if the returned result is 01, it means that the requirements are not met, and the user is reminded that the vehicle does not meet the emission standards and the transportation vehicle needs to be replaced; if the returned result is 02, it means that the vehicle data has not been entered into the vehicle environmental protection information database 501, and the user is reminded that the vehicle information needs to be entered into the database first.

[0048] 5. The purchasing entry management module 404 in the logistics control unit 4 receives the purchasing entry vehicle transportation data issued by the bulk raw material purchasing unit 1 and the material and spare parts purchasing unit 2 through the data interface unit 6, and automatically creates a heavy vehicle entry task according to the license plate number, license plate color, vehicle emission standards, and purchased materials, and sends it to the access control unit 5 through the data interface unit 6.

[0049] 5. The sales and delivery management module 405 in the logistics control unit 4 receives the sales and delivery vehicle transportation data issued by the product sales unit 3 through the data interface unit 6, and automatically creates an empty vehicle entry task according to the license plate number, license plate color, vehicle emission standards, and sales materials, and sends it to the access control unit 5 through the data interface unit 6.

[0050] 6. The access control unit 5 receives the purchase logistics tasks and sales logistics tasks from the logistics control unit 4 issued by the data interface unit 6. When a vehicle arrives at the factory gate, the access control unit 5 automatically determines whether the vehicle has a factory entry task based on the license plate color and license plate number recognized by the license plate capture camera. For vehicles with factory entry tasks, the vehicle task information will be displayed in green text on the vehicle task LED display screen, including the license plate number, vehicle emission standards, loaded or empty vehicles, transport materials, and the unit to which the vehicle belongs. At the same time, the access control gate is controlled to lift the pole and automatically allow the vehicle to enter the factory; for vehicles without factory entry tasks, the vehicle task LED display screen will display the vehicle without a task in red text, and the vehicle will be refused to enter the factory.
