Claim:
A container data center comprising: a container; an electric switch system received in the container; a commercial power supply and an uninterruptible power supply (UPS) connected to the electric switch system in parallel; a plurality of normally closed switches comprising a first switch connected between the commercial power supply and the electric switch system in series and a second switch connected between the UPS and the electric switch system in series; an alarm device; and a controller connected to the normally closed switches and the alarm device, configured for receiving earthquake information containing an earthquake intensity, and configured for controlling the alarm device to activate alarms and controlling some of the normally closed switches or all the normally closed switches to open when the earthquake intensity is equal to or greater than a predetermined earthquake intensity, wherein the earthquake intensity is measured according to the Modified Mercalli Intensity scale, when the earthquake intensity is equal to or lower than a IV, the controller does not respond to the earthquake information; when the earthquake intensity is a V or VI, the controller opens the second switch; and when the earthquake intensity is equal to or larger than a VII, the controller opens the first switch and the second switch.
