<p>PURPOSE:To transmit/receive required measurement data without crosstalk in each system by sending a data at random once at minimum in the collection time interval required for measuring objects. CONSTITUTION:In starting a random timer 1 of an observation station 31, a control signal is sent through a control line 11, a control circuit 5 is operated, the data is fetched via a data line L2 from a sensor 6 to apply processing required for code conversion such as A/D conversion and parallel/serial conversion and the data is sent through a transmitter 7 and a communication circuit 2. When the transmission is finished, the control circuit is in the standby state till the random timer is started next. Through the configuration of the observation station 3 as above, the data is sent at random for several times in the collation time interval required for the measurement object in one system.</p> |
