Remote control system of heading machine

The invention relates to the field of tunneling equipment, and discloses a tunneling machine remote control system which is composed of a first optical fiber switch, a second optical fiber switch, a remote control host, a PLC master station and an ordinary PLC substation, and a worker can output an operation instruction through the remote control host. The operation instructions are sent to the PLC master station through a local area network formed by the first optical fiber switch, the second switch and optical fibers, the PLC master station outputs corresponding action commands to the corresponding ordinary PLC substations according to the specific content of the operation instructions, and the ordinary PLC substations control the corresponding actuators to act so as to control the heading machine to work. The remote control host of the control center and the PLC control system in the working site of the heading machine form a local area network, so that real-time data communication between ...
