Method and system for transmitting data, gateway device, and operating terminal device

A method for transmitting data, applicable to an operating terminal device installed with content management and issuing service software, the method comprising:

• establishing a communication connection with a gateway device, and receiving identification information of at least one electrophoretic display (EPD) table card sent by the gateway device;
• generating an operation interface by the content management and issuing service software based on the identification information of the at least one EPD table card, wherein the operation interface is provided to the operating terminal device for users to operate to display to-be-determined target display content of the at least one EPD table card corresponding to the identification information;
• determining, from the to-be-determined target display content, target display content of the at least one EPD table card through the operation interface, and generating an operation instruction based on the target display content of the at least one EPD table card determined on the operation interface;
• generating display content information of the at least one EPD table card based on the operation instruction, wherein a template is provided on the operation interface and is configured to determine the target display content, and a serial number of each EPD table card and text display information, a display color, a font, and a font size which are to be determined are displayed in the template, the serial number of the EPD table card being in one-to-one correspondence with the identification information of the EPD table card;
• and
• sending the display content information of the at least one EPD table card by the gateway device to the at least one EPD table card.

A system for transmitting data, comprising an electrophoretic display (EPD) table card, a gateway device and an operating terminal device installed with content management and issuing service software:

• the gateway device is configured to:
• receive identification information sent by at least one EPD table card;
• establish a communication connection with an operating terminal device;
• send the identification information sent by the at least one EPD table card to the operating terminal device;
• acquire display content information of the at least one EPD table card from the operating terminal device, wherein the display content information is generated based on an operation instruction of the operating terminal device, the operation instruction being generated based on target display content of the at least one EPD table card determined on an operation interface, the operation interface being generated by the content management and issuing service software based on the identification information of the at least one EPD table card and provided to the operating terminal device for users to operate to display to-be-determined target display content of the at least one EPD table card corresponding to the identification information;
• and send the display content information to the at least one EPD table card based on the identification information of the at least one EPD table card, such that the at least one EPD table card performs display based on the display content information;
• and
• the operating terminal device is configured to:
• establish the communication connection with the gateway device;
• receive the identification information of at least one EPD table card sent by the gateway device;
• generate the operation interface by the content management and issuing service software based on the identification information of the at least one EPD table card;
• determine, from the to-be-determined target display content, the target display content of the at least one EPD table card through the operation interface;
• generate the operation instruction based on the target display content of the at least one EPD table card determined on the operation interface;
• generate the display content information of the at least one EPD table card based on the operation instruction;
• and send the display content information of the at least one EPD table card by the gateway device to the at least one EPD table card;
• wherein a template is provided on the operation interface and is configured to determine the target display content, and a serial number of each EPD table card and text display information, a display color, a font, and a font size which are to be determined are displayed in the template, the serial number of the EPD table card being in one-to-one correspondence with the identification information of the EPD table card.
