RADIO AUTOMATIC GAUGE EXAMINATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To obtain a radio automatic gauge examination system where a radio device accurately discriminates only a radio call to the radio device itself in a short time without being affected by other communication or noise and reduces the consumption of a battery. SOLUTION: A transmission-side radio device continuously transmits system discrimination information, group discrimination information, and terminal discrimination information from a system start signal continuous transmission circuit 9 through a radio transmission circuit 3, and a reception-side radio device detects a radio wave by intermittent carrier sensing operation of a radio reception circuit 2. System discrimination information and group discrimination information are extracted from this detected radio wave by a system discrimination code detection circuit 5 and a group discrimination information detection circuit 6. If terminal discrimination information cannot be detected by a terminal discrimination information detection circuit 8, a control circuit 4 stops the intermittent carrier sensing operation for a prescribed time.
