A brand new global trigger scheme with online vertex fitting has been proposed, aiming at the ultra-low anti-neutrino energy threshold as down to 0.1MeV which is essential for the study of solar neutrino and elastic scattering of neutrinos on supernova burst. With this scheme, the TOF (time of flight) difference of photons fly through the liquid media from the interaction point to the surface of central detector can be corrected online with real time, the width of trigger window to cover the whole period of a specific neutrino generated photons can be significantly reduced which lessen the integrated dark noise introduced from the large amount of PMT devices hence a lower energy threshold can be achieved. The scheme is compatible, flexible and easy to implement, it can effectively extend the physics potential of the JUNO for low energy neutrino research topics.
