Mat for Measuring Type Sleep Status with Unrestricted Type}

The present invention relates to a mat for restraint sleep state measurement, and more particularly, to a mat for restraint sleep state measurement that is installed on the mat to measure the sleep state without restraining the human body.

In modern society, the number of people with sleep abnormalities or sleep disorders is increasing due to night light, noise pollution, and increased number of working hours.The quality of sleep is linked to physical illness as well as drowsiness accident, creating a pleasant sleeping environment. Is required.

On the other hand, while a person sleeps, he or she turns upside down or flips several times at regular or irregular intervals. As a prerequisite for creating a comfortable sleeping environment for a person, it is necessary to accurately measure and analyze the sleeping state of the individual.

As such, a method for measuring a sleeping state of a person has been mainly used in the past using a signal output from such a sensor in the state in which various sensors are attached to the elements of the human body. However, this method requires not only specialized knowledge in the attachment process to the human body, but also a problem that causes a lot of restrictions and inconveniences on the human body's activities during the attachment process and subsequent processes, and furthermore, the natural environment due to tension in the human body. There was a problem that makes it impossible to measure the sleep state at.

In order to solve this problem, a piezo sensor or a force sensing resistor (FSR) sensor is installed on the legs or mat of the bed to detect various weight changes or vibrations caused by breathing or flipping while a person sleeps. The sleep state measurement technology of the unrestrained method which measures sleep state is proposed.

However, in the above-described sleepless state measurement technology, the piezoelectric sensor or the FSR sensor is expensive and the installation cost increases, and since the sensor itself is sensitive, unnecessary signals such as vibrations that do not occur during the sleep process of the human body. There is a problem such that a high performance data processing device is required by sensing.

In addition, when a conventional piezoelectric sensor or FSR sensor is installed on a cushioned mat, the pressure applied to the sensor may not be measured accurately, or even an unnecessary signal such as vibration may be sensed, so that an error value may be corrected or an unnecessary signal may be processed.

It may comprise a plurality of switch wiring patterns 124 arranged in parallel to interconnect them at right angles. As a result, the period wiring patterns 122, 123 and any two switch wiring patterns 124 always form a closed loop. On the other hand, unlike the gap portion B of the bipolar wiring pattern 110, the gap portion D of the connection wiring pattern 120 is physically separated, and as a result, each of the pattern portion C is mutually It will remain electrically disconnected.

First, when the power of the mat is turned on, various variables are initialized in step S10, and again in step S12, it is determined whether an interrupt has occurred (for example, several cycles), and if an interrupt occurs, step S14 is performed. The signals X (n1) to X (n4) from the sensor structure 100 are pre-amplified and A / D converted and input. Next, in step S16, these signals X (n1) to X (n4) are summed, and then divided by the number of sensor structures 100 (four in this embodiment) to obtain an average ((Y (n))). .

Next, in step S18, it is determined whether the value obtained by subtracting the average (Y (n-1)) obtained from the currently obtained average (Y (n)) is greater than the predetermined reversal setting value, in which case the person currently on the mat It is determined that the patient (which may be the patient to be cared for) is still being turned over and the sleep LED 318 is turned on in step S22, and the sleep LED 318 is turned off again in step S24.
