Fall detecting device and fall detecting method

A fall detecting device comprising:

• a detector unit that includes a plurality of tilt sensors each including a pair of electrodes disposed to oppose each other with the positional relationship therebetween being fixed and a conductor capable of freely moving between the pair of electrodes and changing an electrical-connection state between the pair of electrodes by means of the movement of the conductor resulting from a variation in posture of the pair of electrodes, wherein the plurality of tilt sensors are arranged so that directions in which the pairs of electrodes are opposed to each other are perpendicular to each other;
• a multivalued data output unit that acquires the electrical-connection states between the pair of electrodes of the plurality of tilt sensors and converts the acquired electrical-connection state into multivalued data on the basis of the ratios of the electrical-connection states in a predetermined first period;
• and
• a fall determining unit that determines the occurrence of a fall when a moving average value of the multivalued data of the plurality of tilt sensors in a second period is equal to or greater than a first threshold value, wherein the second period is an integral multiple of the first period.
