POWER MANAGEMENT SYSTEM AND POWER MANAGEMENT METHOD

摘要

A power management system has power supplying means, measuring means that measures power generation environment for the power supplying means, and communication means that transmits information measured by the measuring means. The power management system comprises: a control unit that controls the measuring means and the communication means. The power supplying means is used as a power source for the measuring means and the communication means. The control unit sets a first power threshold to be used for determining whether or not to switch operation states of the measuring means and a second power threshold to be used for determining whether or not to switch operation states of the communication means on the basis of a power supply that is supplied from the power supplying means.
