CUBE is a powerful onsite earthquake early warning command center, alarm device and datalogger, featuring visual, voice, and dynamic text display via its 3-phase LED indicator, built-in speaker, and 7-inch touch screen. Similar to PX01, CUBE supports Modbus protocol for users to integrate into the SCADA, MES, or other management programs. The SeedLink protocol is also supported in CUBE for 3rd-party accelerographs to integrate. The N-of-M voting algorithm is included in CUBE, too. Therefore, CUBE is an ideal onsite interface for earthquake early warning and emergency controls. Besides, CUBE embeds HAZUS quick structural damage assessment algorithm (a.k.a. RSHD). Within a minute after a felt earthquake event, CUBE is able to send out the preliminary result based on the stiffness or inter-story drift ratio of a 3-accelerograph system. The RSHD cloud service is also available upon request.
