In order to improve the acquisition efficiency of bar code acquisition technology and the management efficiency of enterprises in the Internet of things, and bring more benefits to related enterprises, the barcode technology of perception layer in the Internet of things was added into the enterprise resource planning system, thus getting an effective and convenient barcode acquisition system. The research results show that the circuit board of the automatic barcode acquisition system studied here is based on the built-in barcode program and joined the enterprise resource planning system. It realizes the connection and integration of the two, which can not only run independently, but also simultaneously, to a large extent, playing its role. It can be seen that the integration of the barcode technology of the perception layer in Internet of things and the enterprise resource planning system can obtain a new industrial automatic barcode acquisition system. It can not only meet the requirements of barcode acquisition, but also improve the efficiency of barcode acquisition, which can be used for reference for manufacturing enterprises in terms of projects that produce according to the order.
