Abstract
An information transfer system includes an information panel which controls electrical equipment and includes a first transmission and reception section. The system also includes a server which is communicably connected via a network to the information panel and includes a second transmission and reception section and a trigger generation section which generates a communication request trigger for making a request to communicate with the information panel. The first transmission and reception section transmits information based on a UDP protocol periodically to the server, the second transmission and reception section receives the information based on the UDP protocol. When the communication request trigger is generated, the second transmission and reception section transmits request response information based on the UDP protocol or based on a TCP protocol to a transmission-origin address of the information.
