PURPOSE:To make the detecting accuracy higher by converting the outputs from pressure detecting units into analog-digitals right and left individually so as to be added and totaling the input values of all guide stable wheels so as to calculate a puncture level and perform puncture judging and correcting a distortion gage output which changes by an extrinsic factor. CONSTITUTION:When a monorail vehicle 1 enters a puncture detecting spot and a tire 3 for a guide wheel and a tire 4 for a stable wheel pass through guide wheel pressure detecting units 5a, 5b and stable wheel pressure detecting units 6a, 6b on a track girder 2, voltages equivalent to the pressure are generated from the guide wheel pressure detecting units 5a, 5b in order, and repeating amplifiers 7a, 7b receive these so as to perform voltage amplification and output to current converters 8a, 8b. When the current converters 8a, 8b convert these voltages in to currents so as to output to transmission passages, voltage converters 9a, 9b receive these and convert them into voltages so as to output to peak hold circuits 10a, 10b. When a maximum value is set here, the value is inputted to an A/D converter 11, and when A/D conversion is completed, reading is demanded with respect to a microcomputer 12. |
