PURPOSE:To prevent missing of data by transmitting an observed data for plural number of times at a time interval set differently at each observing station when the observed data is generated. CONSTITUTION:The observing station consists of a signal producing circuit CT producing a transmission signal, timer circuit TM setting a transmission time interval, transmission circuit TX and a start circuit TG. When an observing signal SIG is inputted to the circuit TG, the circuit CT is started to produce a prescribed pulse signal and the circuit CT starts the circuit TM, and the circuit TM transmits a start signal to the circuit TG after a time set to each observing station. The circuit TG is operated again by a signal from the circuit TM to start again the circuit CT, and produce a pulse signal. |
