<p>PURPOSE:To surely collect the abnormal information of distant/multiple places with simple equipment and with the radio transmission of small energy consumption by setting radio communication devices by each steel tower and collecting the abnormal information of each steel tower to a monitoring center by intermittent radio transmission between radio devices. CONSTITUTION:When any slave station 2 recognizes the abnormal information by a sensor 7, this is temporarily held in a slave station controller 6, radio-transmitted to a radio communication device 5, and transmitted to two slave stations close to a master station 1. Each received slave station 2 is radio-transmitted while adding the information when there is something abnormal in the present station, and is radio- transmitted while the received information as it is from the master station 1 to the slave station 2 when there is nothing abnormal in the present station. This transmission is repeated, and the abnormal information of each slave station 2 is finally transmitted to the master station 1. The slave station 1 holds the information received by a radio communication device 4 in a monitoring controller 3 displays the contents on a display part. Therefore, the abnormal information of each steel tower can automatically be collected by self-start and the radio transmission.</p> |
