基于虚拟仪器技术的城市地下综合管廊施工监测系统设计

针对传统施工监测系统在大型施工现场中无法达到整合各监测参数的效果,导致管廊施工变形的监测精度较低,因此设计一种基于虚拟仪器技术的城市地下综合管廊施工监测系统.系统从硬件与软件两方面进行设计,硬件主要对电路放大器与数据采集卡进行设计与选型,确保处理过的信号可以传榆给计算机的虚拟仪器等工作环境;软件设计中,为保证系统数据的...

Construction of Monitoring System of Urban Underground Integrated Pipe Gallery Based on Virtual Instrument Technology

In view of the traditional construction monitoring system in large construction site can not achieve the effect of system integration of various monitoring parameters,resulting in the low monitoring accuracy of pipe corridor construction deformation.Therefore,monitoring system based on virtual instrument technology for the construction of urban underground pipe corridor is designed.The system design consists of hardware and software two aspects.The hardware mainly designs and selects the circuit amplifier and data acquisition card to ensure that the processed signals can be transmitted to the virtual instrument working environment of the computer.In the software design,in order to ensure the accuracy of the system data,the monitoring coding structure is designed,the side pressure and pipeline curvature of the concrete to the formwork in the alarm parameters are calculated,and the warning value and alarm value are set,early warning of danger is realized by analyzing the data obtained from monitoring.In the system test,a comprehensive pipe gallery is selected for the construction monitoring accuracy test.The experimental results show that the designed system has less monitoring errors in vault settlement,support clearance convergence,and surface settlement than the original system,and the designed system has strong stability during the detection process,which verifies that the designed system is monitoring It has superior performance.
