PROBLEM TO BE SOLVED: To speedily and surely transmit the generation information of event such as fault to a master station without fail when that event occurs by transmitting the generation information of the event from each radio slave station to the other plural slave stations within the range capable of receiving transmitted radio waves from the present station when that event occurs and a transmission request is generated at the master station. SOLUTION: A detailed data signal preparing part 4 and an abnormal information preparing part 10 are respectively connected through a signal switching part 11 to a signal converting part 5. When a sensor 9 is in non-detecting state, ordinarily, the signal switching part 11 switches the detailed data signal preparing part 4 and signal converting part 5 to the side to be connected and holds it. When the sensor 9 performs detecting operation, the abnormal information signal preparing part 10 and signal converting part 5 are switched to the side to be connected. When preparing an abnormal information signal and detailed data signal, the priority is previously applied to the abnormal information signal preparing part 10 and detailed data signal preparing part 4 as the destination of transmission to the other two slave stations within the range capable of receiving the transmitted radio waves. |
