摘要： Sensors distributed along a ropeway communicate with a base station and preferably a base station computer. One type of sensor detects and signals cable misalignments from a normal line of cable traction. Preferably each cable tower has at least one such sensor. Another type of sensor is mounted on a sheave assembly and detects vibrations characteristic of disintegration within the assembly. It produces a sheave problem signal whenever such occurs. Preferably there is one vibration sensor mounted on each sheave assembly. Another type of sensor is preferably mounted on each ropeway carrier for detecting and signaling excessive swings. The sensor signals are communicated to a cable operator so that remedial action can be taken. Each carrier sensor has an RF transmitter for broadcasting its signals to RF receivers mounted on cable towers. Interface units local to sensor groups relay their signals to a base station computer that provides corresponding indicators to the cable operator. Preferably ropeway carrier transmitters and tower receivers are spread spectrum for immunity from outside interference. Preferably the interface units and the base computer communicate via a common data network. Each carrier can also have one or more code transponders which communicate certain unique codes to the base station each time the carrier passes by the station.
