Abstract: A remote electro-hydraulic control system of overhead monorail for cable handling was designed through adding telecontroller and wireless transceiver to existing electro-hydraulic control system of overhead monorail for cable handling. Composition of the system was introduced as well as hardware design of telecontroller and wireless transceiver, software design of the system and operation modes of the telecontroller. The system has functions of the original electro-hydraulic control system, and can remotely control overhead monorail for cable handling by operating the telecontroller in safe distance away from the overhead monorail. Field application verifies stability and reliability of the remote electro-hydraulic control system.
