Control method of electronic table card based on Internet of Things, electronic table card and control terminal

Abstract

The invention discloses a control method of an electronic table card based on the Internet of Things, the electronic table card and a control terminal. The method comprises the following steps: a to-be-updated electronic table card is connected with a control terminal according to a communication mode selected by the user; the communication mode is specifically a WiFi mode, a USB direct connectionmode or a ZigBee mode, the to-be-updated electronic table card receives a drawing command sent from the control terminal based on the connection, the to-be-updated electronic table card determines ato-be-updated screen and a drawing data source according to the drawing command, the drawing data source is specifically a TF card on the control terminal or the to-be-updated electronic table card, and the to-be-updated electronic table card updates the display content of the to-be-updated screen according to the drawing data read from the drawing data source. According to the scheme, the importing speed when the data is imported into the electronic table card is increased, the operation is simplified, and meanwhile, the remote unified management of the electronic table card is facilitated based on the Internet of Things.

Description

technical field [0001] The present application relates to the technical field of application of the Internet of Things, and more specifically, to a method for controlling an electronic table card based on the Internet of Things, an electronic table card and a control terminal. Background technique [0002] When holding a large-scale conference, the identities of the participants are usually displayed by table cards. The display content of the current conference table cards is mainly displayed on paper or plastic materials, which cannot be used repeatedly. Printing and statistics in advance cannot be modified at any time. At the same time, the existing forms of expression and appearance are relatively simple, and it is impossible to realize unified planning and management. [0003] Although in the prior art there is also a scheme of using electronic table cards to be updated for information display, but it generally uses card swiping information input and U disk or SD card d...
