【摘要】 在KIS地震仪表系统中,报警与标定单元是系统的执行机构。系统的报警源和故障监测点以及标定、无阻尼控制等节点繁多,控制逻辑复杂。为了简化系统设计、提高系统的可靠性。以PLC(Programmable Logic Controller,可编程逻辑控制单元)为报警与标定单元的控制执行部件,在该系统中得到良好的应用效果。更多还原

【Abstract】 In KIS-seismic instrumentation,the alarm end test unit are the operative framework of the system.There are so various nodes,including seismic alarm,fault monitoring,testing with no dump,etc.in the system that makes the control logic complex.To simplify system design and improve system reliability,the Programmable Logic Controller(PLC) is used for a implementation part of the alarm and calibration unit and achieve better application effect in this system.更多还原
