The utility model discloses the working process brief notes:
when a transport vehicle carrying a container passes through a portal frame arranged on the advancing channel in a crossing manner, the infrared probe is in two states of interruption and communication in the advancing process of the transport vehicle because the arrangement height of the infrared probe is smaller than the lowest height of the upper edge of the container, and the shooting action of the digital camera is controlled and triggered by the change of the two states.
When the two groups of infrared probes are changed from communication to shielding or from shielding to communication, the receiving heads send signals to the central control unit, the embedded PC A of the central control unit sends shooting commands to the four groups of digital cameras through the embedded PC B of the field control unit respectively, and the digital cameras can shoot box number images of different positions of the container. Thus, after the transport vehicle carrying the container passes through the portal frame, if the transport vehicle is a container, 4 images of the front part, the rear part, the left part and the right part of the transport vehicle can be shot, and if the transport vehicle is a double container, 6 images of different parts of the front container and the rear container can be shot; the shot digital image information is transmitted to the PC through the embedded PC B of the field control unit, the Ethernet switch and the network, and the acquisition and recording work of the digital image information is completed. Because a plurality of digital image information are obtained simultaneously, besides identifying each digital image information, a plurality of obtained identification results can be verified mutually, and therefore the correct container number is obtained.
When the infrared probe 3 is changed from communication to shielding for the first time, the container transport vehicle enters a channel, at the moment, the embedded PC A of the central control unit sends a control signal through the Ethernet switch, an RFIC reader-writer in the wireless radio frequency tag data acquisition unit is started, and the RFIC reader-writer drives a wireless radio frequency RF antenna connected with the RFIC reader-writer to transmit a wireless radio frequency signal; a vehicle-mounted Radio Frequency Identification (RFIC) card arranged on the container transport vehicle receives a wireless signal transmitted by an antenna to obtain energy and transmits data stored in the vehicle-mounted radio frequency identification; the RF antenna receives a data signal transmitted by the wireless radio frequency tag and transmits the signal to the RFIC reader-writer; the reader-writer analyzes the wireless signals, decodes the data of the license plate number, the self weight of the vehicle and the like in the wireless signals, and transmits the data to the PC through the Ethernet switch to finish the work of collecting and recording the license plate number data.
The vehicle weight is obtained by the influence on the pressure sensing circuit when the transport vehicle passes through the wagon balance, the total weight of the vehicle is sent to the dynamic weighing instrument through the wagon balance, and the dynamic weighing instrument transmits the weight data of the whole vehicle to the PC through the embedded PC A of the central control unit and the Ethernet switch, so that the collection and recording work of the vehicle weight data is completed.
When the number of the displayed wagon balance is larger than a certain limited threshold value (such as 9 tons), a carrier vehicle is passing the wagon balance; when the carrier vehicle completely enters the wagon balance, a relatively stable extreme value appears in the display number of the wagon balance, and the value is the total weight of the carrier vehicle and the container. The dynamic weighing instrument transmits the data to the PC through the embedded PC A of the central control unit and the Ethernet switch through the serial interface, and acquires and records the data. Subsequently, the number of the displayed wagon balance is continuously reduced along with the leaving of the carrying vehicle, and when the difference between the displayed number and the stable extreme value is larger than a certain defined threshold (such as 3 tons), a vehicle is considered to have left, and the weight detection time sequence of the next vehicle is started simultaneously.
After the device acquires Data information such as a container number, a license plate number, a vehicle weight and the like of the passing vehicle, the PC compares the acquired Data with the content in a service system database on a customhouse EDI (Electronic Data Inter-change) platform in real time, and checks whether the weight of goods carried by the passing vehicle is consistent with the declared weight; if the signals are consistent, the PC sends a release signal, an embedded PC A in the central control unit outputs a green light on and release gear lever lifting control signal, an LED display screen displays information that the pass is qualified and the vehicle passes, and the carrier vehicle can continue to move forwards through the pass gate; if the comparison result is inconsistent, the PC sends a prohibition signal, the central control unit outputs a red light lighting control signal, the LED display screen displays that the inspection is unqualified and the vehicle enters the inspection yard for inspection, and the carrier vehicle cannot pass through the closing gate, so that the rapidness, the automation and the integration of data acquisition and supervision operation on the closing gate of the container are realized.
Because the utility model discloses need not artificial intervention, can accomplish a series of field data's collection automatically, comparison and pass floodgate control work, use manpower sparingly, 24 hours full-automatic unmanned monitoring has been realized, license plate data acquisition accuracy is high, and adopt the initiative light source technique, can guarantee to shoot clearly under the all-weather condition, and is stable, the high-quality container number image, the data direct transfer that its was gathered reaches the customs database, can be used by customs EDI business system, the inseparable combination of data contrast on field data acquisition and the customs EDI business system platform has really been accomplished, data acquisition on the container pass floodgate has been realized, control and supervision operation's rapidization, it is automatic, the integration.
The utility model discloses but wide application in the customs inspection station of airport, harbour, limit inspection.
