Abstract

A living body information detecting terminal (2) is controlled from the side of a living body information monitoring device (3) connected to the living body information detecting terminal (2). In particular, a first living body information detecting sensor that is driven at all times or a second living body information detecting sensor that is in a power-save state or performs measurement in an intermittent manner during normal conditions, is selected, determined, and controlled from among living body information detecting sensors (5) provided to the living body information detecting terminal (2) depending on its wearer, and the second living body information detecting sensor is operated with transmission of an abnormality signal from the first living body information detecting sensor as a trigger. As a result, reductions in power consumption and data volume are attained, and a living body information detecting terminal control system with improved reliability is realized by verifying, at regular time intervals, the operation condition of the living body detecting sensor that is in a power-save state during normal conditions.
