This paper investigates the fixed-time (FXT) consensus problem of second-order multi-agent systems (SOMASs) via event-triggered intermittent control. To begin with, a new event-triggered intermittent control protocol (EICP) with sampled-data is designed and an auxiliary function is integrated into this design to precisely determine the duration of the discontinuous control intervals. Furthermore, by utilizing the FXT stability theory and inequality-based techniques, several conditions for attaining FXT consensus are derived. Finally, a numerical example is presented to validate the efficacy of the proposed control protocol and the main results.
