Description

A kind of harbor gate clearance system based on radio-frequency (RF) identification

Technical field

The present invention relates to a kind of harbour service management system, especially relate to a kind of harbor gate clearance system based on radio-frequency (RF) identification.

Background technology

Radio-frequency (RF) identification (RFID, Radio Frequency Identification) is a kind of contactless automatic identification technology, it is by the automatic recognition objective object of radiofrequency signal and obtain related data, and identification work need not manual intervention, can work in various rugged surroundings.

The RFID ultimate system comprises label (Tag) and reader (Reader), and label mainly is made up of coupling element and radio frequency chip, and each label has unique electronic code, when using label, only needs it attached to identifying destination object on the object; Reader is used for reading the information of each connected label, and reader sometimes also can writing information, and it can be designed to hand-held or fixed; Transmit radiofrequency signal with intercommunication mutually by label and reader antenna (Antenna) separately between each label and the reader.The basic functional principle of RFID ultimate system is: after label enters magnetic field, receive the electromagnetic wave that reader sends, and rely on energy that induction current obtained to send out to carry the radiofrequency signal that is stored in the product information in the radio frequency chip, carry out decoding processing after the radiofrequency signal that the reader reading tag sends and to radiofrequency signal, and decoded data are delivered to the back-end data processing unit carry out data processing; Perhaps label initiatively sends the radiofrequency signal of a certain frequency to reader, carries out decoding processing after the radiofrequency signal that the reader reading tag sends and to radiofrequency signal, and decoded data is delivered to the back-end data processing unit carry out data processing.The former described label is a passive label, or is called passive label (Passive Tag); The described label of the latter is an active label, or is called active tag (Active Tag).

Existing RFID technology is mainly used in logistics and supplies management, the manufacturing and assembling, aviation luggage are handled, mail/fast freight is wrapped up aspects such as the automatic charge of processing, document tracking/library management, animal identification sign, motion timing, gate inhibition's control/electronic entrance ticket and road, but in the container wharf application facet bigger development do not arranged also.

The loading and unloading operation of domestic and foreign trade container ship mainly is engaged in the container wharf, and relevant plan layout, the gathering of chargeing, checks work such as clearances, receipts case suitcase.

At present, the sluice gate of container wharf is most to adopt the mode of labor management to arrange personnel that the reservation of the container truck that advances/leave the port number, car plate and container information data are checked at the road junction of each sluice gate, checks errorless could the clearance.The labor management container truck advances/leaves the port the mode of flow process, causes shortcomings such as container truck is low by the inefficiency of sluice gate, intelligent degree, cost height.
