RADIO TERMINAL EQUIPMENT FOR WHOLESALE MARKET AUCTION

摘要

PROBLEM TO BE SOLVED: To quickly and accurately process the data necessary for an auction and its participants, to automatically register the data to a computer and to automate the data processing by transmitting and fetching those data by radio via the bidder and participant terminal units. SOLUTION: An MCU(microcontroller unit) 1 controls a program memory, a data memory and an input/output module to carry out the arithmetic and transfer processes, etc., which are necessary for execution of given tasks. Then the MCU 1 performs the prescribed control of a bidder terminal unit and the auction participant terminal units based on the operation control information on the application software stored in a PROM(programmable ROM) 4. At the same time, an IFP(interface processor) 2 controls a radio module 3 to secure connection between the MCU 1 and the module 3 and also controls the transfer of data to the MCU 1 from the module 3.
