Description
The Water Cherenkov Detector Array (WCDA) of the LHAASO project is to be built in Daocheng, Sichuan Province of China. It comprises of 4 neighboring ponds, each in dimension of 150 m $\times$ 150 m, and divided into 900 cells, with a PMT in each cell. A triggerless scheme is to be adopted for the data acquiring system, in which all the single channel signals are synchronized and transferred to an online computing cluster, to build into events based on a dedicated trigger pattern. The trigger pattern is introduced in this paper. The feature of the trigger pattern is noise tolerance and scalability, and it can be generalized for some other air shower experiments.
