Abstract: Based on the existing sensor laboratory bench, an intelligent monitoring system was designed and implemented using a multi-channel data acquisition board and programmable analogue switches. All the sig-nals of major nodes in the test bench were acquired and displayed through Lab VIEW; Using the graphical display function of virtual instrument, the dynamic acquisition and display of experiment data were imple-mented and the experiment range of test bench was expanded; After real-time monitoring the key points of the test bench, faults can be located quickly and the maintenance cost of laboratory equipment is reduced significantly.
