In a particular implementation, the sensor may be an infrared sensor. In the use, the sensor sends and receives the infrared ray in check out test set, and when electronic card inserted check out test set, the infrared ray was sheltered from to the electronic card for the infrared ray can't be received to the sensor, and the sensor can generate and send and shelter from signal to check out test set.
In this embodiment, after the detection device receives the shielding signal sent by the sensor, it can be determined that the electronic card is inserted into the detection device.
And 204, when the sensor detects that the electronic card is inserted, responding to the operation instruction to scan the electronic card and generating scanning data, wherein the scanning data comprises the line number of the image data of the electronic card.

It should be noted that the detection device may monitor the current working state, may monitor the moving speed of the electronic card, and may monitor the volume of the scanned data. When the electronic card is connected and scanned, a plurality of rows of scanning data can be acquired, and the scanning data can be refreshed once when one row of scanning data is received.
In a specific implementation, newly received scan data can be superimposed on original scan data, and the scan data is stored continuously without being disconnected.
And step 206, storing the image data of the electronic card, and calculating the line number of the image data of the electronic card.
It should be noted that the detection device may be provided with a storage unit that may be used to store the image data and a monitoring recording unit that may be used to record the number of lines for calculating the image data.
In actual operation, the detection equipment can write the image data into the storage component while acquiring the image data of the front side and the back side of the identity card, so that the image data can be stored in real time, and the condition of data loss during scanning can be avoided. While the monitor recording section may record the number of lines for calculating the image data written in the storage section.
The number of lines of the recorded image data is calculated, and it is possible to determine whether the image data is image data of a larger capacity or image data of a smaller capacity. For example, if the capacity of the image data is large, the memory corresponding to the image data is large, and the number of lines written into the storage unit is large; if the capacity of the image data is smaller, the memory corresponding to the image data is smaller, and the number of lines written into the storage component is smaller.
Whether the image data need to be split or not can be determined by calculating the line number of the specific image data, the image data is split and transmitted, if the image data is large, the image data can be split and respectively transmitted, and if the image data is small, the image data can be directly transmitted. Therefore, the efficiency of image data transmission can be improved, and the waiting time of a user can be shortened.
And step 207, determining a target line number according to the line number and the scanning mark.
In this embodiment, if the image data obtained after scanning is large, the image data may be cut and split into a plurality of image data blocks, and the plurality of image data blocks are sent to the terminal.
In specific implementation, the target line number of the image data can be determined, and the size of the split image data block is determined by the target line number, so that the split of the larger image data can be realized, the real-time transmission can be realized, the partial image data can be immediately transmitted after being acquired, the transmission difficulty can be reduced, the transmission time can be shortened, and the image data transmission efficiency can be improved. In this embodiment, the target line number may be determined by determining whether the current line number is the same as the target line number.
In this embodiment, step 207 may include the following sub-steps:
substep 2071, obtaining the current number of rows.
In this embodiment, the current number of lines may be obtained by obtaining the number of lines of the currently stored image data, or the number of lines may be obtained by starting calculation when the image data is received.
Substep 2072, determining whether the current number is equal to or less than a preset number.
In the present embodiment, the preset number may be preset by a user, and may be 100 lines, 200 lines, 300 lines, and so on. Preferably, there may be 200 rows.
Comparing that the current number is the same as the preset number, and if the current number is the same as the preset number, taking the line number of the image data corresponding to the current number as the target line number.
Substep 2073, if the current number is equal to the preset number, taking the number of lines corresponding to the preset number as the target number of lines, and repeating the step of obtaining the current number of lines.
In this embodiment, the preset number may be 200 lines, when the current number of the line numbers of the image data is equal to 200 lines, 1 to 200 lines corresponding to the image data may be used as the target line number, and the image data of 200 lines may be used as the target image data to transmit the target image data.
After the target line number is determined, the detection device transmits the image data corresponding to the target line number, so that after the target line number is obtained, the line number of the image data corresponding to the current number can be recalculated, and the calculation can be started again by 1.
For example, after 200 lines of image data are obtained, the calculation is performed for 201 lines of image data starting from 1, and 200 lines of image data are counted again.
Substep 2074, determining whether to acquire the scan flag if the current number is less than the preset number.
It should be noted that the scanning flag may be an end flag, or may be generated after the scanning component scans the entire identity card.
In a specific implementation, the number of lines of the generated image data is not necessarily an integer, and may be 90 lines, 105 lines, 123 lines, or the like. When the scanning is finished, the detection device can generate an end mark to avoid repeatedly storing the image data.
When the end mark is generated, the remaining image data can be directly transmitted, and the integrity of the acquired image data is ensured.
Substep 2075, if the scan flag is obtained, taking the number of lines corresponding to the current number as the target number of lines.
In this embodiment, when the scan flag is obtained, it may be determined that the scanning is completed, and the number of lines of the remaining image data may be directly set as the target number of lines.
For example, after scanning 200 lines, the detection apparatus restarts calculating the number of lines, counts the number of lines of image data from 1, and after reaching 66 lines, acquires the scan flag, and determines the remaining 66 lines as the target number of lines.
Optionally, step 207 may further comprise the sub-steps of:
substep 2076, repeating the step of obtaining the current number of rows if the scan flag is not obtained.
If the scan mark is not obtained, it can be determined that the image data has not been scanned, the image data can be stored continuously, and the number of lines of the image data needs to be calculated.
And 208, generating a feedback data packet from the scanning data according to the target line number.
In specific implementation, 200 lines of corresponding image data can be packed to generate a feedback data packet, and the feedback data packet is sent to a terminal, so that transmission time can be shortened, and the effect of collecting and transmitting at the same time is realized.
In this embodiment, step 208 may include the following sub-steps:
and a substep 2081, packaging the image data of the electronic cards with the corresponding number according to the target line number to obtain packaged data.
It should be noted that the encapsulated data may be a data packet that maps image data into a payload of a certain encapsulation protocol, and then fills a header of the corresponding protocol to form the encapsulation protocol. The encapsulation protocol may be a point-to-point protocol (PPP), an Extensible Authentication Protocol (EAP), and so on.
In actual operation, when the number of lines of the image data is the same as the preset number of lines, the detection device may encapsulate the image data corresponding to the preset number of lines to obtain a corresponding encapsulated data. For example, the preset number of lines is 200 lines, the scanning unit obtains image data when scanning the identification card and transfers the image data to the storage unit row by row, and the monitoring and recording unit may calculate the number of lines of the image data written in the storage unit from 1 to 100. When the number of lines in which the image data is written is 100, the detectable device may encapsulate the image data of lines 1 to 100 to obtain encapsulated data. Then, the number of lines of the image data to be written next to the memory section is continuously calculated, and the calculation is repeated from the 1 st line to the 100 th line
Substep 2082, packaging the encapsulated data to generate a feedback data packet.
In this embodiment, after the image data with the preset number of lines is encapsulated according to the encapsulation protocol, the encapsulated data may be encapsulated to generate a data packet, where the data packet may be a feedback data packet.
The image data contained in the feedback data packet is small, transmission is fast, and data transmission efficiency can be improved.
In this embodiment, after one or more feedback data packets are obtained, the feedback data packets may be sent to the terminal one by one.
Specifically, in order to improve transmission efficiency, after each feedback data packet is generated, the feedback data packet may be sent to the terminal once, and the terminal may splice and derive complete image data according to the sequence of the received feedback data packets.
Referring to fig. 4, a schematic diagram of the connection of the detection apparatus of the present invention to a terminal is shown. In this embodiment, the terminal may be a pc terminal, and the detection device may be a scanner, and optionally, the scanner employs an SOC chip of Xilinx Zynq 7007S as a CPU unit.
Referring to fig. 4, the pc terminal may be connected to the scanner through a USB cable. In the pc terminal, an application driver (DRV for short) may be installed, and firmware control software (FW for short) may be installed in the scanner, where the firmware control software may include PS control software (PS for short) and PL control software (PL for short), and the PS control software and the PL control software may perform data interaction through a protocol bus, and specifically, the protocol bus may be an AXI (Advanced eXtensible Interface, AXI for short).
Specifically, the application driver DRV may be configured to generate a corresponding operation instruction according to an operation of a user at the pc terminal, and receive a data packet of image data sent by the PS control software.
The PS control software can be used for receiving and analyzing an operation instruction transmitted by the application driver DRV through the USB, realizing service logic control according to the requirement of the operation instruction, sending the operation instruction to the PL control software through the AXI bus, receiving a data packet sent by the PL control software, and sending the data packet to the application driver DRV through the USB line.
The PL control software can be used for implementing an operation instruction transmitted by the PS control software, acquiring a data packet of corresponding image data, and feeding back the data packet to the PS control software through the AXI bus.
