The work aims to design a bar code detection method, so as to efficiently, conveniently and safely detect the portable digital electronic detonators. Firstly, the composition of the bar code printed on the detonator was analyzed to propose a new type of analog electronic detonator bar code detection method. The image processing and recognition of the image containing bar code was carried out by combining with the embedded bar code system under the Matlab software platform. Under MATLAB, the barcode in the image could be accurately identified, and the embedded barcode scanning could display the correct barcode sequence within 5.1 ms. Compared with some existing bar code recognition software on the market, the embedded bar code scanning system has good adaptability and accuracy, which will make the detonator scan entry in the portable detonator more convenient and efficient and provide a basic guarantee for the function of the subsequent detonator.
