Abstract: With the introduction of the concept of smart rocket，new challenges are posed to the data acquisition technology of launch vehicle.There are still problems in the launch vehicle，such as limited measurement field，low measurement accuracy and reliability，poor scalability and low tailorability.Based on the analysis of the current situation and problems of data acquisition summarizes the trend of data acquisition toward intelligence，networking，light weight and high efficiency is summarized.Combined with the trend research and judgment，the overall framework of data acquisition for a rocket is given，and the advantages，disadvantages and application scenarios of various key technologies such as structural health monitoring，fiber optic sensor network，and cable free are compared and analyzed.The application prospects of fiber grating sensor network，wireless sensor network，magnetic resonance wireless energy transmission and other technologies in smart rocket data acquisition are proposed.

Key words: Smart rocket, Intelligent, Data acquisition, Sensing, No cable
