Abstract:
1. An apparatus for operating power plant equipment of a power plant worksite through a network by a remote control signal through wireless communication from the power plant worksite, said apparatus comprising: a mobile operation terminal for inputting a signal of a requested operation of said power plant equipment and generating a radio wave signal of the input signal, said operation terminal being movable to an optional point of possible moving routes thereof at said power plant worksite; a plurality of wireless transceivers located in the power plant worksite, with each of said wireless transceivers being located at a respective appropriate point of said routes in order for wireless communication with said mobile operation terminal by the generated radio wave; and a control device connected to said power plant equipment and connected to said wireless transceivers and an operation device in a central control room via said network, wherein the requested operation of said power plant equipment is effected under control of said control device enabled with a control signal transmitted from one of said wireless transceivers enabled with its receipt of the radio wave signal generated by said mobile operation terminal, wherein operation of said power plant equipment is monitorable by said mobile operation terminal in a timely and immediate manner without contact with said central control room, said operation device in the central control room is operatively configured to electrically connect to said wireless transceivers via the network to establish communication between said operation device and said mobile operation terminal through the network and the wireless transceiver, said mobile operation terminal is operatively configured to issue an alternative to an operation request issued by said operation device to said control device through the wireless transceiver and the network to operate said power plant equipment without making contact with the central control room, and said operation device in the central control room is operatively configured to display state information concerning the alternative operation request issued by said mobile operation terminal on a screen of said operation device.
