[0041] The barcode identification module 110 is configured by the barcode recognition operation logic unit 111, and is electrically connected to the data storage module 101 and the data decoding module 120. The barcode recognition operation logic unit 111 performs code type identification on the barcode image stored in the data storage module 101. If the identification is successful, the Bessie data decoding module 120 outputs the code type, otherwise the recognition fails, and a signal is sent to trigger the data storage module 101 to continue receiving the next frame barcode image.

[0042] The data decoding module 120 has at least two or more decoding operation logic units, is electrically connected to the barcode identification module 110 and the data storage module 101, and triggers corresponding signals according to the code type signal transmitted by the barcode recognition operation logic unit 111.

[0044] The present invention further provides a barcode decoding scheme of the system as described above: The image acquisition module collects a sequence of barcode image frames, and transmits the frame to the data storage module 101 frame by frame. When the data storage module 101 receives the barcode image of a frame, it will send A signal is sent to the barcode identification module 110, and the trigger barcode recognition operation logic unit 111 performs code type identification on the barcode image. If the recognition is successful, a code type signal is output to the data decoding module 120. If the recognition fails, the recognition error signal is returned, and the trigger is triggered. The data storage module 101 continues to receive the next frame of the bar code image. The data decoding module 120 triggers the decoding operation logic unit (one of 121~12n) of the corresponding code system to decode the barcode image according to the code type signal given by the barcode identification module. If the decoding is successful, the decoding result is output, and a decoding success is returned. Signal, otherwise return a decode failure signal. Next, the data storage module 101 continues to receive the next frame barcode image, ready to enter the decoding of the next frame barcode image.

2 is a schematic diagram of a workflow of an intelligent gating barcode decoding chip according to an embodiment of the present invention. The specific implementation steps of the embodiment of the present invention are as follows: [0046] 1. The image acquisition module collects a sequence of barcode image frames;

[0047] 2. The data storage module 101 receives a frame of bar code image;

[0048] 3. Bar code recognition operation logic unit 111 identifies the bar code image code type, if the recognition fails, then returns an identification error signal, step 2 is performed, if the recognition is successful, then a code type signal is output to the data decoding module 120;

[0049] 4. Trigger the corresponding decoding operation logic unit (one of 121~12n) to decode the barcode image, if the decoding fails, return a decoding failure signal, perform step 2, and if the decoding is successful, output a decoding success signal,吋 output decoding result;

[0050] 5. Perform step 2, preparing to start decoding of the next frame barcode image.

[0051] The smart gating barcode decoding chip adopts a hardware integration method instead of software decoding, which can effectively improve the overall decoding speed. The bar code recognition operation logic unit replaces the traditional decoding software code recognition module, which effectively improves the code recognition speed; replaces the software decoding module with each code decoding operation logic unit, effectively improves the decoding speed, and greatly improves the bar code of the unknown code system. Decoding rate.
