Based on LabVIEW virtual instrument,multi-sensors,wireless bridge and GPRS transmission tech-nology,an intelligent real-time monitoring system for proximity construction near the existing metro lines is put forward with due consideration of a certain under-pass construction on Beijing subway Line 4.In each monito-ring section,multiple sensors are connected to the safety automatic monitoring acquisition instrument.Monitoring signals are transmitted wireless to the receiving end at the tunnel entrance by network bridge transmitter module built in the acquisition instrument,then sent to the Internet packed by GPRS module.PC monitoring terminal calls monitoring data from the Internet,and uses the unified data management platform designed by LabVIEW to make analysis and early warning,to generate reports and store queries.The system realizes real-time monito-ring for proximity existing metro lines and tunnels′structural changes,and provides construction safety assess-ment,timely warning and control measures as well as dynamic and precise adjustment of track quality parame-ters,which guarantees the operational safety of the existing metro.
