<p>PROBLEM TO BE SOLVED: To reduce constitution cost for the overall system, facilitate operation, and reduce standby power by transmitting detected information of each steel tower by selecting the optimum radio equipment fitting to the system of an aerial transmission line, and to enable application toward a long distance aerial transmission line, without being affected by a distance between a start end side steel tower and a terminal end side steel tower, by transmitting a request signal in sequence. SOLUTION: Information detecting and transmitting units 11A,..., 11F which detect information concerning steel towers are installed in the respective steel towers 1A,..., 1F which constitute a transmission line. A request signal transmitted from central monitoring equipment 2 of a power station A is transmitted in sequence from the start end side information detecting and transmitting unit 11A to the terminal end side information detecting and transmitting unit 11F. Information of each steel tower is transmitted in sequence from the terminal end side information detecting and transmitting unit 11F to the central monitoring equipment 2 via the information detecting and transmitting units 11E,..., 11A. Detected information is displayed regarding each of the steel towers.</p> |
