Old man enters toilet, and toilet tumble detection alarm detects someone's entrance, into detection triggering state.Always
People normally goes to toilet, and toilet tumble detection alarm is not detected by tumble identification condition 1,2,3,4, is also not detected by falling
Identification condition 5, i.e., completing to go to toilet in 30 minutes does not complete and from toilet.Toilet tumble detection alarm detects old man
Leave, do not report to the police, into holding state, wait human body next time to enter triggering.If detecting tumble in detection triggering state
Identification condition 1,2,3 or 4, Falls Among Old People were not got up within the 5S times, then toilet tumble detection alarm sends alarm sound
With RF alarm signals；It is not detected by tumble identification condition 1,2,3,4 when going to toilet in old man, but the time that goes to toilet is more than 30min
When, triggering tumble identification condition 5, toilet tumble detection alarm sends alarm sound and RF alarm signals.If in alarm sound
Send, then reporting to the police stops.
Referring to Fig. 4, the course of work of toilet tumble detection alarm is divided into three steps：
When toilet tumble detection alarm is first powered on, there is an initialization learning process, when learning initialized
Between about 13S.There should not be human body on effective detection face below when toilet tumble detection alarm is first powered on.Initialization
Learning process will record value of the infrared thermoinduction thermopile array detection to ambient temperature, thing on surveying record vertical plane
The height of body.Usually, toilet tumble detection alarm " learns " the effective detection face for recording lower section in initialization procedure
Height, as initial value L.
When having detected human body and entering, toilet tumble detection alarm will initialize the height of study process record and make
Making comparisons with the human height H for detecting for initial value L, ending with reference to there is the infrared thermoinduction thermopile array background of sensor
Lattice change the double mirror of recognizer and Height-measuring algorithm and differentiate whether the attitude of human body is to fall or faint, Chinese mugwort lattice change recognizer and
Height-measuring algorithm is prior art, and it will not go into details for the present invention.
Through between initialization study rear guard's life of about 13S, tumble detection alarm enters normal work.In normal work
When someone enters toilet, the intensity that detection light is shone by environmental sensor first, if at illumination not enough such as dusk or night, connect
State indicator module relay is lighted and illuminates light fixture.Turned on light when old man does not leave always illumination, detect old man and leave 5S
After turn off the light.There are perspective plane lattice of the infrared thermoinduction thermopile array detection human body of detection sensor in 64 area's lattice simultaneously
