The invention belongs to the field of collection equipment and use methods, and particularly relates to a two-dimensional code collection system and method. The system comprises a two-dimensional codecollection all-in-one machine, a cloud server and a mobile data terminal. The two-dimensional code collection all-in-one machine comprises a two-dimensional code generation module, an Mqtt collectioninformation subscription module, an Https device registration module, a Bluetooth module, a distribution network module and the like. Under the Wi-Fi network, the network distribution unit is connected with the network distribution module, so that the two-dimensional code collection all-in-one machine is connected with the mobile data terminal and the cloud server by accessing the Wi-Fi network.In the absence of a Wi-Fi network, the Bluetooth unit is connected with the Bluetooth module, so that a data channel is established between the mobile data terminal and the two-dimensional code collection all-in-one machine. The two-dimensional code collection all-in-one machine logs in and accesses the cloud server through the mobile data terminal. The two-dimensional code collection system has the advantages that: firstly, the two-dimensional code collection all-in-one machine can be used no matter whether a network is available or not; secondly, the machine has portability and mobility, anddoes not depend on wiring; and thirdly, audios such as music and news can be played, and dual functions of entertainment and collection are realized.
