<P>PROBLEM TO BE SOLVED: To provide a bed sensor system in which determination omission from the initial stage of the system starting to presence of bed-leaving is few and determination accuracy of presence of the bed-leaving after starting the system can be easily improved. <P>SOLUTION: The bed sensor system 1 includes: a sheet-like sensor 2 disposed on bedding 9 of a care receiver P and having a sensor film 20 made of an elastomer; a controller 3 including a memory unit 30 storing reference data and threshold data and a calculation unit 31 to compare calculation data based on body pressure distribution of the care receiver P with the reference data to determine the posture of the care receiver P and to compare the time change of calculation data with threshold data to determine whether the care receiver P leaves the bed or not to output notice indication when the bed-leaving is determined; a notice device 4 to transmit a bed-leaving notice to a care giver; and an input device 5 into which error determination information is input from the care giver. In the controller 3, determination accuracy of the presence of bed-leaving is improved by correcting the threshold data on the basis of the error determination information. <P>COPYRIGHT: (C)2012,JPO&INPIT |
