摘要
矿用隔爆型信号仪利用煤矿井下现有的660V动力线路,通过载波和计算机编码、解码技术实现声光信号的接收和发射,在同一频道上通过内部设置的编码开关可实现一机传递16种不同频率的信号,保证信号接收的唯一性,以避免串频产生误动作,从而省去大量的电缆,极大地降低成本,减少维修工作量;同时,具有显示光信号和配接线的功能,通点后就能有效工作。
The paper deals with application of the mine explosive-proof signal instruments,which can transmit 16 kinds of different frequency signals with a device through calculator codes switch to guarantee the unique signal received,to avoid mistake acts,to save electric cable and to reduce maintenance.
