METHOD FOR TRANSMITTING WIRELESS SIGNAL FOR STACKER/RECLAIMER AUTOMATION OF THERMAL POWER PLANT

摘要

Purpose: a kind of method, the tracker/reclaimer automated setting for being used for transmission a radio signal for a thermo-power station use a kind of wireless local area network method at the main mounting cost that reduces. Construction: a laser distance signal of a measurement unit (1) is sent to an input/output unit (2). One output signal of input/output unit is changed into a digital signal, and digital signal is to be modulated by one converter/feeler signal modulator (3) as a radio signal. The wireless output signal of aerial signal converter is sent to a first antenna (4). By an aerial signal demodulator/network (5), the radio signal of antenna being received is demodulated. Demodulated signal is sent to a PLC/PC (6). It is changed into digital signal in the vision signal of a tracker/reclaimer installation video camera, digital signal is to modulate by one video signal converter/transceiver (7) as wireless signals. Wireless signals are sent to one second antenna (8). The wireless signals of antenna being received are demodulated, and demodulated signal is converted into analog video signal by one video signal demodulator/transceiver (9). Analog video signal is shown by a monitor (10).
