Step 18, acousto-optic output element receive the instruction in step 17 and send out urgent call sound.
3rd, application scenarios：
When old man lies in it is intellectual nursing bed upper when, if old man's sleeping position is in left side compressing cardiac position, and according to microcomputerThe heartbeat signal that electric transducer detects, processing controller calculate heart rate data, it is found that when slight abnormality occurs in old man,Processing controller automatically controls acousto-optic output element playing alert tones prompting old man and adjusts posture.If time-out does not adjust, the present inventionDrive component control unit can by adjusting intelligent bed body respective activity component automatically by the pose adjustment of old man to lie low,If continuing to detect the data exceptions such as heart rate and the respiratory rate of old man, pre-set children and guardian number can be put through immediatelyCode is helped.
There are cough or abnormal groan, and old man is detected with reference to weight sensor when sound transducer detects old manTurn data and the ambient condition such as day-night change signal of light sensor detecting, processing controller in bed can pass through instructionSo that the respective activity component of the intelligent bed body of drive component control unit adjustment, is sitting posture by the attitude regulation of old man, avoid oldPeople may cause the abnormal of respiratory disorder to occur because the objects such as phlegm occurs in respiratory tract.
When detecting old man's may be infected bedsore by gas sensor, processing controller can be driven by instructingThe respective activity component of the intelligent bed body of component control unit adjustment, helps old man periodically to realize that turn acts, avoids for a long time notBedsore caused by turn infects.Which reduce the artificial burdens of nursing staff.
When warm and humid sensor detecting to old man's aconuresis leads to the humidity exception of mattress, processing controller, which is notified that, to be addedHot ventilation unit automatically turns on aeration-drying, further reduces the risk of bedsore infection.
When being in night's rest when light sensor and weight sensor detect old man, and having frequent turn, placeReason sensor can indicate acousto-optic output element play automatically sleeping music alleviate old man anxiety help fall asleep.
When weight sensor detects the weight change signal occurred when old man leaves intellectual nursing bed, processing controllerStart recording when more than the preset time, issues instructions to acousto-optic output element from the bed time；Acousto-optic output element sends out reportAlert sound and alarm light signal, nursing staff to be reminded to pay close attention to the situation of old man.
When old man will be drunk water or be got up in the night to urinate when nursing staff is needed to help, emergency call button is pressed, touches processing controlDevice processed issues instructions to acousto-optic output element, and acousto-optic output element sends out urgent call sound immediately, nursing staff to be called out to comeHelp.
The present invention can also provide the continuous measurement of physiology sign data：The respiratory movement letter of micro-electro-mechanical sensors detecting human bodyNumber and heartbeat signal and weight sensor detecting human body change posture movements signal, more than signal is sent to processing controlDevice processed；After processing controller receives the signal detected, continuous human body respiration rate and heart rate are obtained in real time by built-in algorithmAnd frequency data are turned over, and teach remote server and carry out Trend tracing, while can send out in time when there is abnormal occurIt delivers newspaper alert to preset mobile terminal.
The preferred embodiment of the present invention described in detail above.It should be appreciated that those of ordinary skill in the art withoutCreative work is needed according to the present invention can to conceive and makes many modifications and variations.Therefore, all technologies in the artPersonnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's ideaTechnical solution, all should be in the protection domain being defined in the patent claims.
