INFORMATION TRANSMISSION SYSTEM, INFORMATION TRANSMISSION METHOD, ELECTRIC DEVICE COMMUNICATION DEVICE, INFORMATION COMMUNICATION DEVICE, COMMUNICATION CONTROL PROGRAM

摘要

There are provided an information transmission system, an information transmission method, an electric device communication device, an information communication device, and a communication control program. An information panel (1) controlling an electric device (3) includes a first transmission/reception section (11). A server (2) communicably connected to the information panel (1) via a network (4) includes a transmission/reception section (21) and a trigger generation section (22) for generating a communication request trigger for requesting communication with the information panel (1). The first transmission/reception section (11) periodically transmits information based on the UDP protocol to the server (2). The transmission/reception section (21) receives information based on the UDP protocol transmitted periodically and, upon generation of a communication request trigger, transmits request response information based on the UDP protocol or request response information based on the TCP protocol to the source address of the information based on the UDP protocol.
