The　remote　automatic　continuous　monitoring　system　has　four　functions-,　data　acquisition,　exchange,　processing　and　feeding　back.　This　system　is　composed　of　scene　monitor　and　data　acquisition　system,　the　master　control　computer　system　and　client　system.　The　scene　monitor　and　data　acquisition　system　is　installed　in　the　station　and　is　composed　of　EL　beam　sensor,　intelligent　jointmeters　and　crackmeter,　intelligent　displacement　meter　and　CRIOX　data　logger.　The　master　control　computer　system　is　installed　in　the　platform　office.　The　client　is　installed　in　the　monitor　company,　the　construction　company　and　the　operation　company　respectively.　The　monitor　system　can　operate　automatically,　and　it　can　be　altered　to　the　hand　control.　According　to　the　monitor　data　analysis　which　has　been　carried　on　the　regression　method,　we　can　forecast　the　finally　displacement　value　and　the　line　security　condition.　This　system　is　applied　in　the　5th　line　which　cross　Yonghegong　station　of　the　2nd　line,　the　orbital　isostructuralism　distortion　situation　can　be　obtained　promptly,　and　the　normal　operation　of　the　2nd　line　is　safeguarded　in　the　course　of　excavating.
