Embodiment Construction
[0052] like figure 1 As shown in the flow chart of the first embodiment of the data downloading method of the present invention, it should be explained first that the handheld terminal may be a device such as a smart phone or a tablet computer commonly used by users at present. The user's handheld terminal first establishes a connection with the server. For example, the handheld terminal and the server are in a local area network, and the connection is established through WIFI. Of course, the handheld terminal can also establish a connection with the server through Ethernet. In addition, the server is connected to the database, and a plurality of serial numbers and files corresponding to each serial number are pre-stored in the database. The data downloading method of this embodiment includes:
[0053] A. After the user obtains the two-dimensional code, the handheld terminal scans the two-dimensional code and sends a download request to the server, where the download request ...

The invention discloses a data download method and system. The data download method comprises the steps that after a two-dimensional code is acquired by a user, the two-dimensional code is scanned by a hand-held terminal, a download request is sent to a server, and the download request comprises a server address, a port number and a serial number; whether the serial number in the received download request exists in a database is judged by the server, multiple serial numbers and files corresponding to all the serial numbers are pre-stored in the database, and the next step is executed if the judgment result is yes; error information is returned to the hand-held terminal if the judgment result is no; verification of the server is passed, return information is sent to the hand-held terminal, the corresponding file is searched in the database according to the serial number in the download request, and the searched file is processed and then sent to the hand-held terminal; and the hand-held terminal receives the return information and file information from the server and plays the file information. With application of the technical scheme, user experience is great and cost is low.
Description
technical field [0001] The invention relates to the field of data transmission, in particular to a data download method and system. Background technique [0002] When tourists visit museums, exhibition halls, historical sites, etc., especially when viewing exhibits with a strong historical and cultural background, they often need to obtain background knowledge about the exhibits. However, at present, there are several ways for tourists to understand relevant knowledge: 1. Through the tour guide's explanation, but sometimes, the tour guide's explanation of some knowledge is not very detailed, and the tourists need to follow the tour guide closely, otherwise the relevant explanation may be missed, Therefore, the user experience is poor; (2) Learn relevant knowledge through the audio guide system in the exhibition area. However, this method requires a guide terminal for each tourist, and special personnel are required to manage these terminals, which greatly increases the compl...
