Description
Technical field
The utility model relates to a kind of automotive number plate recognition device, relates in particular to a kind of automotive number plate true-false decision apparatus.
Background technology
The recognition technology of the traditional vehicle trade mark, great majority are realized number plate identification and realized number plate and identify by increase the mode of Quick Response Code in license plate number by software, the efficiency of identification is low, the low current number plate identification of accuracy rate of identification does not realize the number plate true and false and distinguishes, the trick-plate true and false is distinguished the working experience that depends on people, therefore in vehicle uniqueness confirmation work, be difficult to carry out the defect that realizes number plate identification by increase the mode of Quick Response Code in license plate number, need to upgrade to existing license plate number, enforcement difficulty is large, cost increases, ultimate cost will be transformed into it car owner, first the technological deficiency of finding in the technical scheme contrast of prior art and this patent shows as: depend on specific platform, as the number plate identification operating on andriod platform can not operate in other IOS systems, software repeated usage rate is low, by software, come identification software failure rate to be greater than hardware fault rate.
Utility model content
The purpose of this utility model provides a kind of automotive number plate true-false decision apparatus with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Automotive number plate true-false decision apparatus of the present utility model comprises ccd image sensor, picture signal is processed and row/field synchronization separator, arm processor, EEPROM, SDRAM, the one Flash memory, the 2nd Flash memory, WIFI communication part and antenna, the data communication end of described WIFI communication part respectively with the data communication end of described arm processor, the data communication end of EEPROM, the data communication end of the one Flash memory and the data communication end of PC are connected, the signal transmission ends of described WIFI communication part is connected with described antenna, the control signal end of described PC is connected with the control signal end of described arm processor, the startup control output end of described arm processor is connected with the startup control input end of described WIFI communication part, the output transmission ends of described arm processor respectively with the data transmission terminal of described SDRAM, the data transmission terminal of the 2nd Flash memory processes with described picture signal and the first data transmission end of row/field synchronization separator is connected, described picture signal is processed and the second data transmission terminal of row/field synchronization separator is connected with the data transmission terminal of described ccd image sensor.

Accompanying drawing explanation
Fig. 1 is the structural principle block diagram of automotive number plate true-false decision apparatus of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: automotive number plate true-false decision apparatus of the present utility model comprises ccd image sensor, picture signal is processed and row/field synchronization separator, arm processor, EEPROM, SDRAM, the one Flash memory, the 2nd Flash memory, WIFI communication part and antenna, the data communication end of WIFI communication part respectively with the data communication end of arm processor, the data communication end of EEPROM, the data communication end of the one Flash memory and the data communication end of PC are connected, the signal transmission ends of WIFI communication part is connected with antenna, the control signal end of PC is connected with the control signal end of arm processor, the startup control output end of arm processor is connected with the startup control input end of WIFI communication part, the output transmission ends of arm processor respectively with the data transmission terminal of SDRAM, the data transmission terminal of the 2nd Flash memory processes with picture signal and the first data transmission end of row/field synchronization separator is connected, picture signal is processed and the second data transmission terminal of row/field synchronization separator is connected with the data transmission terminal of ccd image sensor.
As shown in Figure 1: the utility model automotive number plate authenticity identification method, comprises the following steps:
(1) user distinguishes that by the number plate true and false rule writes the 2nd Flash memory by PC, then WIFI is configured to firmware data writes a Flash memory;
(2) terminal use sends information by the wireless signal transmission mode of antenna to WIFI communication part;
(3) WIFI communication part obtaining information be sent to arm processor by Three S's PI interface;
(4) arm processor resolve command send acquisition to ccd image sensor;
(5) image that ccd image sensor gathers through picture signal, process and row/field synchronization separator after by the final view data of arm processor collection;
(6) arm processor inside draws number and the true and false judged result of number plate and feeds back to user PC by WIFI communication part.
As shown in Figure 1: WIFI communication part of the present utility model is responsible for transceiving data.By arm processor, controlling WIFI communication part starts, when starting, by Three S's PI interface, to WIFI communication part, send firmware data and be stored to EEPROM and a Flash memory by a SPI interface and ErSPI interface branch, WIFI communication part is from the success of PC loading firmware data, then carry out firmware data, carry out WIFI communication part initiation parameter configuration (as MAC Address, operating frequency, transmitting power) etc.After WIFI communication part parameter sets up, whole system just can be carried out normal data transmit-receive with other 802.11b wireless communication terminal, and data packet format is controller+IP bag, can use inquiry mode and DMA interrupt mode during transfer of data.Under DMA interrupt mode, while sending data, by PC, to equipment dma operation, send to WIFI communication part, while accepting, packet is sent to arm processor by Three S's PI interface after arriving, and arm processor is accepted data.
