全电子自动复原道岔模块的研究
Research on All electronic Switch Automatic Recovery Module
摘要
Abstract
The automatic recovery module of four-wire switch of all electronic computer interlocking systems is introduced to replace the former switch executive circuit made of safety relay. The module includes micro-programmed control unit, complex programmable logic device, switch driving circuit, switch indication circuit, switch detection circuit and automatic recovery circuit. The computer interlocking system determines the MCU timing when there is an indicative voltage in the positioning and reversing detection units. When the timer reaches pre-set time and the switch fails to close at the stipulation time, MCU activates electric relay Js and the control system sends out reversed switching order for automatic recovery via Js contact. Finally, the scheme of software design is proposed and the working principle of the software is illustrated with flow chart.关键词
