The USB interface adapter 403 is plugged into the image playing device 401, and the image playing device 401 establishes a lan communication connection between the network cameras paired with the USB interface adapter according to the connection with the USB interface adapter 403.
Referring to fig. 5, an alternative flow chart of a data display method applied to the data display system in the above embodiment is shown. The data display method comprises the following steps:
s501: the method comprises the steps that the image playing device detects that a USB interface adapter is inserted, and a designated file storage space of data transmitted through the USB interface adapter is built;
s502: the image playing device triggers the USB interface adapter to send a pairing request;
s503: the USB interface adapter searches whether a paired network camera exists, if not, step 504 is executed; if yes, go to step 507;
s504: the USB interface adapter sends a pairing request to a network camera in a network in a local area network communication mode;
S505: the network camera returns a response instruction to the USB interface adapter based on the pairing request;
s506: the USB interface adapter is paired and bound with the network camera based on the response instruction;
S507: and the image playing device establishes local area network communication connection between the network cameras matched with the USB interface adapter through the USB interface adapter.
S508: the USB interface adapter is used for transmitting the image data output by the network camera to a designated file storage space established by the image playing equipment;
S509: downloading and installing a video player by the image playing equipment;
S510: and the image playing device extracts the image data from the designated file storage space according to a playing instruction and plays the image data through the video player.
According to the data display method, the data transmission and corresponding storage can be completed under the environment condition of local area network communication by inserting the image playing device between the network camera and the image playing device through the USB interface adapter, so that the method is suitable for external environment conditions without Internet, and the data collected by the network camera can be played on various image playing devices which can be connected with the USB interface adapter, and the diversity, convenience and instantaneity of the network camera in data display are remarkably improved.
