Abstract
PURPOSE: To obtain a traveling-body detector which requires no special limitation as to installation conditions without being influenced by a fluorescent lamp, by equipping a microwave generating part, receiving detection part, AC amplifier, level testing circuit, pulse generating circuit, counting circuit and informing circuit.
CONSTITUTION: By the output signal of level testing circuit 4, pulse generating circuit 5 outputs a pulse signal continuing for a constant time and the number of output pulses of level testing circuit 4 during this pulse generation period is counted by counting circuit 6; when the count value reaches a fixed value, information circuit 7 starts operating. In this system, only one rectangular pulse voltage appears at level testing circuit 4 because of a high pulsating voltage developed when the fluorescent lamp comes on or goes off, and counting circuit 6 generates no output. Therefore, even when a microwave generating source modulated by a component of power frequency 50Hz or 60Hz or its higher harmonics such as the fluorescent lamp adjoins, the influence of it is not exerted and traveling body 10 can stably be detected.
