System and method for judging abnormal condition based on inertial sleeping position

An abnormal condition judging system and method thereof, in particular, a system and method for judging an abnormal condition according to an inertial sleeping posture.

In recent years, advanced countries have devoted themselves to the research and development of medical technology. In order to reduce the burden of medical care and care, the research and development of care systems has yielded fruitful results in academia or industry.

For example, some manufacturers have proposed video surveillance services with monitoring and home security functions. Users only need to install a network camera (IP Cam) and a preset emergency contact phone number or e-mail account to access the computer or 3G. Mobile Internet access instantly monitors the status of your home or company to monitor specific locations. In addition, there is also a help-seeking device that is carried around, and after the caregiver encounters an emergency, the button on the rescue device can be pressed, and the monitoring host disposed around the caregiver is automatically connected to the care center for two-way image transmission. , for proper processing. In addition, some manufacturers have proposed to track the activities of the followers by Radio Frequency IDentification (RFID), and use the Sensing Social Health system to visually track through the sensors and video phones embedded in the home. And record the situation in which the followers interact with others every day.

However, although the various care services described above do reduce the burden on caregivers, the above-mentioned methods all transmit images of caregivers, which is a serious problem that violates privacy and dignity.

Therefore, there is also a care system that places the sensing module under the bathroom, the mattress and the ground to record the data of the caregiver at various locations, and to judge the possibility of occurrence by comparing the time and habits of the caregivers at various locations. Fall or other abnormal conditions, instant notification of ambulance System support, etc.

However, for some unconscious behaviors, for example, changes in sleeping position often have no rules to follow. Therefore, the care system using the sensing module cannot predict when the caregiver will appear what kind of action, so The possibility of misjudgment is quite high, resulting in the inability of the care system using the sensing module to effectively provide care in this situation.

In summary, it can be seen that in the prior art, there has been a long-standing problem that the false positive rate of the abnormal situation caused by the sleeping posture is high. Therefore, it is necessary to propose an improved technical means to solve this problem.

According to the present invention, it can be determined whether the care recipient has a physiological abnormal condition according to the sleeping posture of the care recipient. In order to avoid erroneously judging the new sleeping position of the care recipient as an abnormal situation, the present invention can also cause the physiological abnormality of the care recipient after the sleeping position of the care recipient and the old sleeping posture are different several times. situation.

Hereinafter, the system operation of the present invention will be described with reference to the system architecture diagram of the present invention for determining an abnormal condition based on the inertial sleeping position. As shown in FIG. 1, the system of the present invention includes a pressure sensitive module 100, a transfer module 200, and a master terminal 300.

The pressure sensitive module 100 is responsible for generating a pressure signal. Generally, when the caretaker is lying on the back, lying on the bed or lying on the bed and contacting the pressure sensitive module 100, the caretaker will give the pressure sensitive module 100 a certain degree of pressure, and the pressure sensitive module 100 can be based on The pressure given by the caregiver in contact with it produces a corresponding pressure signal.

The pressure sensitive module 100 is usually laid on the bed of the care giver. Since the caretaker is lying on the back, lying on the back or lying on the bed, the pressure sensitive module is laid on the bed of the care giver. There are a plurality of 100, and it is particularly worth mentioning that any two pressure sensitive modules 100 can be closely arranged adjacent to each other on the bed, or can be arranged on the bed at a certain distance. The present invention is not special. limit.

The number of the transfer module 200 and the pressure sensitive module 100 are the same, and the transfer module 200 and the pressure sensitive module 100 have a one-to-one correspondence. Generally, the transmission module 200 is disposed in the same position as the pressure sensing module 100, but the invention is not limited thereto.

The transmitting module 200 is responsible for transmitting the pressure signal generated by the corresponding pressure sensing module 100 to the main control terminal 300 after the corresponding pressure sensing module 100 generates a pressure signal. The pressure signal is transmitted between the transmission module 200 and the pressure sensitive module 100 through the connection line. The transmission network 200 and the main control terminal 300 usually use the wireless network technology to transmit the pressure signal, but the present invention does not To this end, that is, the transmission module 200 and the host terminal 300 may also use a wired network to transmit pressure signals.

The main control terminal 300 is responsible for comparing whether the pressure signal transmitted by the transmission module 200 is similar to the previously stored historical signal, and accumulating the number of consecutive times that the pressure signal is not similar to the historical signal. When the continuous number reaches a certain value, the main control terminal 300 will determine that the care recipient has an abnormal condition. The main control terminal 300 further includes a signal receiving module 310, a signal comparison module 330, a storage medium 340, and an abnormality determining module 350, as shown in FIG.

The signal receiving module 310 is responsible for receiving the sensing mode transmitted by each of the transmitting modules 200. The pressure signal generated by group 100. The signal receiving module 310 differs according to the network technology used by the transmitting module 200 to transmit the pressure signal.

The signal comparison module 330 is responsible for comparing whether the pressure signal received by the signal receiving module 310 is similar to the historical signal previously stored in the storage medium 340. In general, the signal comparison module 330 compares the pressure magnitude, the pressure strength, and the pressure relative position indicated by the pressure signal with each historical signal one by one, and generates a presence or absence with the signal receiving module 310 after the comparison. The result of the comparison of the received historical signals with similar pressure signals.

The storage medium 340 is responsible for storing the pressure signal received by the signal receiving module 310. After the pressure signal received by the signal receiving module 310 is stored, it becomes a historical signal. In general, the storage medium 340 stores the pressure signal after the signal comparison module 330 compares the pressure signal received by the signal receiving module 310, but the invention is not limited thereto.

The abnormality determining module 350 is configured to determine the caretaker when the number of consecutive times that the signal received by the signal matching module 330 is not equal to the historical signal stored in the storage medium 340 reaches a certain value. An abnormal condition has occurred.

The abnormality determining module 350 may accumulate the continuous number of times when the signal comparison module 330 is not similar to the historical signal, and may accumulate consecutively when the signal comparison module 330 compares the pressure signal with the historical signal. The number of times is zero, but the manner in which the abnormality determining module 350 determines that the number of consecutive times that the pressure signal is not similar to the historical signal reaches a certain value is not limited to the above.

In addition, the present invention may also add a message transmission module 390. The message transmission module 390 is responsible for transmitting an alert message to the specific device when the abnormality determination module 350 determines that the caretaker has generated an abnormal condition. The specific device is pre-defined, usually a mobile phone or a computer, but the invention is not limited thereto. In addition, the message transmission module 390 can transmit the warning message to the specific device by using a short message, an email, or the like.

Next, an operation system and method of the present invention will be described with reference to an embodiment. Referring to FIG. 3, a flowchart of a method for determining an abnormal condition based on an inertial sleeping posture according to the present invention will be described.

In order to use the present invention to care for the care recipient in the caregiver's bed, it is first necessary to lay the pressure sensitive module 100 on the bed of the care recipient (step 510). In this embodiment, it is assumed that the pressure sensitive module 100 is a soft thin layer pressure sensitive gasket, and it is assumed that the pressure sensitive module 100 is laid on the bed of the careless person without any gap, and each pressure sensitive pad A corresponding transfer module 200 is provided on the chip.

After the pressure sensitive module 100 is laid on the bed of the caregiver (step 510), once the master terminal 300 starts operating, the master terminal 300 can provide the care mechanism of the caretaker.

When the caretaker sleeps or rests on the bed, the caretaker presses on one or more pressure-sensitive modules 100 for lying, lying, lying, etc., so that the caregiver and the pressure-sensing module 100 contacts. At this time, the pressure sensing module 100 detects the pressure generated by the weight of each part of the head, the hands and the feet, the body, and the like. Therefore, the pressure sensing module 100 generates the weight of each part of the person being cared for. The pressure signal corresponding to the applied pressure (step 530).

Then, the pressure sensing module 100 can transmit the pressure signal to the main control terminal 300 through the transmission module 200 disposed thereon (step 540). In this embodiment, it is assumed that the transmission module 200 transmits the pressure signal generated by the pressure sensing module 100 to the main control terminal 300 by using a wireless network technology such as ZigBee.

After the pressure sensing module 100 transmits the pressure signal to the main control terminal 300 through the corresponding transmission module 200 (step 540), the signal receiving module 310 of the main control terminal 300 can receive the sensing module 100 through the corresponding transmission mode. The pressure signal transmitted by the group 200, and then the signal comparison module 330 of the master terminal 300 can compare the pressure signal received by the signal receiving module 310 with the historical signal previously stored in the storage medium 340 ( step 550), then, the abnormality determining module 350 of the master terminal 300 can determine that the caretaker has a physiological abnormal condition when the number of consecutive times that the signal matching module 330 does not match the historical signal reaches a certain value. (Step 560).

In this embodiment, assuming that the sleeping posture of the caretaker is a habitual sleeping posture, the signal comparison module 330 compares the pressure signal with the historical signal, and thus, the abnormality determining module 350 of the main control terminal 300 It will be determined that the care recipient has not developed a physiological abnormal condition.

If the caretaker's sleeping position is not a habitual sleeping posture, the signal comparison module 330 compares the historical signals that are not similar to the pressure signal. In this way, the abnormality determining module 350 of the master terminal 300 starts to accumulate the number of consecutive times, and it is assumed that the abnormality determining module 350 will accumulate the number of consecutive times from 0 to 1.

If the abnormality determining module 350 determines that the value used by the caretaker to generate an abnormal condition is three, since the number of consecutive times is still less than three, the abnormality determining module 350 does not determine that the caretaker has a physiological abnormal condition, and It is judged that the caretaker does not have an abnormal situation, and the caretaker is prevented from merely having an occasional sleeping posture, and the physiological abnormality of the cared person is misjudged.

Then, if the caretaker changes the sleeping position to the habitual sleeping position again, the signal comparison module 330 compares the pressure signal with the historical signal, so that the abnormality determining module 350 of the main control terminal 300 determines the care recipient. No physiological abnormalities were generated and the cumulative number of consecutive times was zeroed.

If the sleeping position that is changed by the caretaker is still not used to sleeping, the signal comparison module 330 will also compare the historical signals that are not similar to the pressure signal. The abnormality determining module 350 of the master terminal 300 also continues to accumulate the number of consecutive times, that is, the number of consecutive times is accumulated from 1 to 2. When the sleeping position of the third and fourth changes of the caretaker is still not a habitual sleeping posture, the continuous number of times accumulated by the abnormality determining module 350 will come to 4, and the abnormality determining module 350 It will judge the physiological abnormality of the caretaker, so that it is necessary to change the sleeping position to obtain a more comfortable feeling. In this way, the present invention can judge whether the care recipient has a physiological abnormal condition according to the difference in the sleeping posture on the premise of reducing the false positive.

In addition, after the signal comparison module 330 of the master terminal 300 compares the pressure signal received by the signal receiving module 310 with the historical signal previously stored in the storage medium 340 (step 550), the storage medium 340 The pressure signal received by the signal receiving module 310 can be stored, so that the pressure signal received by the signal receiving module 310 becomes the historical signal for comparing the next signal providing module 330 (step 570).

In addition, if the master terminal 300 further includes the message transmission module 290, after the abnormality determination module 350 of the master terminal 300 determines that the caretaker has a physiological abnormal condition, the message transmission module 290 can transmit the warning message to the specific Device (step 580). Assuming that the specific device in the present embodiment is a mobile phone of the child of the care recipient, the message transmitting module 290 can transmit a short message indicating that the caretaker has a physiological abnormal condition to the mobile phone after reading the number of the mobile phone. In order to inform the caretaker's children of the care recipient, the effectiveness of care can be improved.

In summary, it can be seen that the difference between the present invention and the prior art is that it has a similarity between the received pressure signal and the previously stored historical signal, and the number of consecutive times that the comparison pressure signal is not similar to the historical signal reaches a certain number. When the value is determined, the technical means for determining the abnormal condition of the caretaker can be solved by the technical means to solve the problem that the prior art has a high false positive rate of the abnormal situation caused by the sleeping position, thereby achieving continuous sleep. Care for the technical effects of the caregivers.

Furthermore, the method for determining an abnormal condition according to the inertial sleeping position of the present invention can be implemented in a combination of hardware, software or hardware and software, or can be implemented in a centralized manner in a computer system or spread over several different components by different components. Even the decentralized way of implementing computer systems.
