Description

A kind of boats and ships checking hand-held device based on RFID and image recognition

Technical field

The utility model belongs to exchanges data, certificate recognition technology field, and is particularly a kind of based on RFID and image recognition boats and ships checking hand-held device.

Background technology

The ship's papers inspection is that the checking of maritime patrol department is controlled and the necessary regulation of navigation technology personnel qualification is examined, and is to ensure navigation safety, safeguards the method that the waterborne traffic order is the most frequently used.Ship's papers of a great variety and on form disunity, content emphasize particularly on different fields, so the on-site verification personnel are difficult to the accurate identification of naked eyes.At present, main RFID electronic label technology, two-dimensional bar and the image recognition technology of adopting of certificate false proof identification, because the anti-counterfeiting technology that the department that awards a certificate of various ship's papers adopts is different, ship's papers may have one or more in RFID electronic tag, two-dimensional bar, security stamp or the signature.Cause the on-site verification personnel in the situation that lack corresponding inspection apparatus only can be by to the paper quality of certificate, whether the true and false and content of seal estimates checking with aspects such as the boats and ships situation conform to, can't embody the advantage of new technology aspect quick identification certificate, development employing RFID electronic tag and two-dimensional bar internal information along with technology is easier to be read simultaneously, crack and revise, this just so that the part shipowner in order to pursue private interests, escape set-fee, reduce the illegal operation purposes such as cost, forge or revise on the basis of original certificate and adopt, the means such as smear, attempt is got by under false pretences, thereby make the hidden danger ship that does not meet the navigation regulation jeopardize safety of traffic on water, destroy normal navigation environment, upset ship-handling order etc., the development of the serious restriction of this state shipping industry waterborne.

Summary of the invention

The purpose of this utility model is to provide a kind of boats and ships checking hand-held device based on RFID and image recognition, be applicable to maritime patrol, shipping control examination of law enforcement, simultaneously security stamp, signature, RFID electronic tag or the two-dimensional bar etc. of ship's papers are identified and checking, to reach the purpose of Quick Acquisition certificate information, the real-time query certificate true and false.

A kind of boats and ships checking hand-held device based on RFID and image recognition, housing is arranged, tested ship's papers comprise RFID electronic tag and two-dimensional bar, the GPRS/3G equipment that has communication system to be communicated with, terminal computer, the circuit that it is characterized in that the interior computer processor of described hand-held device and module connects: be included as each functional module of boats and ships checking hand-held device the power management module of power supply and the rechargeable battery that is attached thereto are provided, power management module connects computer processor through power circuit, reset circuit, keyboard is for computing machine provides frequency of operation, the function of system reset and input message; Power circuit also connects RAM module, FLASH module, EEPROM module and the LCD display that is connected with computer processor I/O interface by data bus, is used at operating process storage and show certificate content information; Power circuit also connects the photo module that is connected respectively by general Asynchronous Serial Interface UART and computer processor, certificate information RFID module for reading and writing, the GPS module of position coordinates, the GPRS/3G module of input information; Computer processor is invoked at the certificate content analysis of EEPROM module memory storage and verification system and carries out wireless telecommunications by GPRS/3G module and long-range GPRS/3G equipment and terminal computer.

Advantage of the present invention: the boats and ships checking hand-held device that the utility model proposes carries out double verification based on RFID and image recognition technology to ship's papers, can identify simultaneously the much informations such as RFID electronic tag, two-dimensional bar, security stamp, signature and certificate content, simplify ship inspection personnel's operating process, the more important thing is the archive information that also can use supervision department when guaranteeing to go on board work, to guarantee check accuracy test; The ship's papers content adopts plain text encryption Wen Geshi to store, and the mode by long-range transmission licencing key decrypting ciphertext information, the possibility of avoiding cracking and forging RFID electronic tag and two-dimensional bar; Also have the function of signing and issuing interim RFID electronic tag, provide convenient measure for check and change certificate in the future.
