Detailed description of the invention
Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
With reference to Fig. 1, the embodiment of the present invention provides a kind of pressure sensing device Work state reminding method, including step:
S1, obtain pressure sensing device working signal;
S2, by described working signal with preset signal threshold value compare, if working signal in change procedure sometime equal to signal threshold value, then send the signal reminding pressure sensing device normal operation, otherwise, do not send the signal reminding pressure sensing device normal operation.
As described in above-mentioned steps S1, it is necessary to get the working signal of pressure sensor apparatus, then just can carry out follow-up correlated judgment processing procedure, send the signal that pressure sensing device duty is reminded timely. In the present embodiment, above-mentioned pressure sensing device can export the sensor of corresponding signal for piezoelectric transducer, piezoelectric film sensor, pressure transducer, dynamic Magnetic Sensor etc. because of pressure change.
As described in above-mentioned steps S2, above-mentioned signal threshold value is a signal value that pressure sensing device can be made to reach by conventional means. in the present embodiment, require only working signal in change procedure sometime equal to signal threshold value time, just can send the signal reminding pressure sensing device normal operation, otherwise do not send the signal reminding pressure sensing device normal operation, that is, only user changes making the working signal that certain action makes pressure sensing device collect, and is only possible to the signal obtaining reminding pressure sensing device normal operation. when pressure sensing device gather working signal for a long time more than, equal to or less than threshold signal time, all without trigger remind pressure sensing device normal operation signal, it is possible to greatly reduce the energy consumed because sending alerting signal. in one embodiment, one mattress arranges pressure sensing device, when human body couches in mattress, within general 1000 Ns of the pressure signal that pressure sensing device in pad collects, such as signal threshold value is set as 500 Ns, the body weight of the person of couching is 60 kilograms, the pressure signal that so pressure sensing device collects is at about 600 Ns, when when couching on mattress of human body held stationary, working signal and pressure signal are in about 600 Ns, although more than signal threshold value, but the process of being not changed in, so not sending the signal reminding pressure sensing device normal operation, and go to bed the overshoot couched at user, or the process left the bed, working signal will necessarily at a time equal to 500 Ns, so namely the signal reminding pressure sensing device normal operation can be sent, and now, under conventional use habit, time user wants to check pressure sensing device whether normal operation just, both the instructions for use of user can have been met, the consumption of energy can be saved again, improve the cruising time of pressure sensor apparatus. in other embodiments, signal threshold value can set according to actually used situation, the user body weight of such as mattress is 40 kilograms, the amendment that so signal threshold value can be corresponding, can set that to be 500 Ns, 300 Ns or 400 Ns etc., when the pressure signal produced more than user sole mass, can not arrange too high, generally to ensure that the impulsive force that mattress is produced by human body in the process gone to bed can reach signal threshold value and be preferred.
