Multifunctional all-optical fiber non-intrusive state monitoring thin mat

Abstract

The invention discloses a multifunctional all-optical fiber non-intrusive state monitoring thin mat. The thin mat comprises a first mat layer, a second mat layer and a state monitoring system, whereinthe state monitoring system comprises a power supply, a state sensor, a photoelectric converter, a microprocessor module, a display module, a warning module, a storage module and a data transmissionmodule; the state sensor is arranged between the first mat layer and the second mat layer, a first optical fiber is arranged between a light source and an input end of the state sensor, and a second optical fiber is arranged between an output end of the state sensor and the photoelectric converter; and the microprocessor module comprises a microprocessor, an analog-digital conversion module and astate analyzing module, and the analog-digital conversion module is connected between an output end of the photoelectric converter and the microprocessor. The multifunctional all-optical fiber non-intrusive state monitoring thin mat can be applied to non-contact human body state monitoring such as bed-off detection, bed-sitting detection, body movement recording and sleeping posture monitoring andis wide in application range.

Description

technical field [0001] The invention relates to the field of electronic medical equipment, in particular to a multifunctional all-fiber non-invasive condition monitoring thin pad. Background technique [0002] Condition monitoring plays a vital role in health care, especially in hospital ward care. In order to ensure the safety of inpatients, the hospital needs to know their activity status on the hospital bed at all times. The condition monitoring device can help the hospital to better management of patients. The problem of nursing care for the elderly living alone brought about by the aging population is also becoming more and more serious. The status monitoring device can provide strong security for the elderly living alone. For child care issues, parents can take care of their children more conveniently with the help of condition monitoring devices. For people with sleep disorders, status monitoring can help them monitor their physical status. [0003] For condition m...

Problems solved by technology

This type of method requires a large sensor area and cannot realize sleeping position monitoring

[0012] It can be seen that none of the above-mentioned monitoring methods can integrate the monitoring of leaving the bed, sitting on the bed, body movement, and sleeping position. They can only monitor one or two of them, and the accuracy and portability need to be improved.
