AGRICULTURAL FACILITY REMOTE SWITCHGEAR THAT USE BINARY CDMA/WCDMA SIGNAL

摘要

PURPOSE: An agricultural facility remote closing/opening apparatus is provided to share a resource of a gateway with an endnode terminal within a specific range. CONSTITUTION: An RF(Radio Frequency) conversion and transmission unit receives an A/V signal of a camera module(13). The RF conversion and transmission unit performs RF conversion and transmission of a binary CDMA/WCDMA signal module. A transmission microcomputer(15) selects the RF conversion and transmission channel. An audio/video IF(Intermediate Frequency) circuit generates an A/V IF signal. An A/V signal generation circuit generates the A/V signal. A reception microcomputer controls VCR recording and receiving channel selecting.
