  The Gravitational Wave Burst High-energy Electromagnetic Counterpart All-sky
Monitor (GECAM), consists of 2 small satellites that each contain 25 LaBr3
(lanthanum bromide doped with cerium chloride) detectors and 8 plastic
scintillator detectors. The detector signals are read out using a silicon
photomultiplier (SiPM) array. In this study, an acquisition algorithm for
in-orbit real-time SiPM array data is designed and implemented, and the output
event packet is defined. Finally, the algorithm's efficacy for event
acquisition is verified.
