Description

The present invention relates to a central processing unit and a central processing method of a monitored person monitoring system that monitors a monitored person to be monitored by using a plurality of devices, and the monitored person monitoring system.

Japan has an aging society due to the improvement of living standards, sanitary environment and medical standards accompanying the postwar high economic growth, more specifically, the aging rate, which is the ratio of the population aged 65 and over to the total population. Has become a super-aging society with more than 21%. In 2005, the total population was about 127.65 million, while the number of elderly people aged 65 and over was about 25.56 million, while in 2020, the total population was about 124.11 million. It is estimated that the elderly population will be about 34.56 million. In such an aging society, the nurses and long-term care recipients who need nursing care or nursing care due to illness, injury, or aging are the nurses who need nursing care in a normal society that is not an aging society. The increase is expected more than the above. Japan is also a society with a declining birthrate, for example, with a total fertility rate of 1.43 in 2013. For this reason, elderly care is also occurring in which elderly families (spouse, children, siblings) take care of elderly nurses requiring nursing care.

Nursing needs are admitted to hospitals and facilities such as welfare facilities for the elderly (short-term admission facilities for the elderly, nursing homes for the elderly, special nursing homes for the elderly, etc. under Japanese law) to receive nursing and long-term care. In such a facility, a nurse or the like may be injured due to, for example, falling from the bed or falling while walking, or may get out of the bed and wander. It is necessary to respond to such a situation as soon as possible. Moreover, if such a situation is left unattended, it may develop into a more serious situation. For this reason, at the facility, nurses, caregivers, etc. regularly patrol to confirm their safety and condition.

However, the increase in the number of nurses cannot keep up with the increase in the number of nurses required, and the nursing industry and the long-term care industry are chronically short of labor. Further, since the number of nurses, caregivers, etc. decreases in the semi-night shift and night shift hours as compared with the day shift hours, the work load per person increases, and therefore, the reduction of the work load is required. In addition, the situation of elderly care is no exception in the facility, and it is often seen that elderly nurses and the like care for elderly nurses and the like. In general, as the elderly get older, their physical strength weakens, so even if they are healthy, the burden of nursing etc. becomes heavier than that of young nurses, and their movements and judgments become slower.

In order to reduce such labor shortages and the burden on nurses, there is a need for technology that complements nursing work and long-term care work. For this reason, in recent years, research and development of a monitored person monitoring technique for monitoring (monitoring) a monitored person who is a monitoring target to be monitored, such as a nurse requiring nursing, has been researched and developed.

As one of such techniques, for example, there is a nurse call system disclosed in Patent Document 1. The nurse call system disclosed in Patent Document 1 is installed in a bed for a patient to call a nurse, and is installed in a nurse station to answer a call by the nurse call slave unit. A nurse call system having a nurse call master unit, in which a camera that images a patient on the bed from above the bed and a state in which the patient is upright and the patient is away from the bed from the images captured by the camera. The nurse call master unit has a state determining means for determining the occurrence of at least one of them and outputting a caution state generating signal, and the nurse call master unit has a notification means for performing a notification operation in response to the caution state generating signal. Then, this nurse call system receives the mobile terminal carried by the nurse to answer the call from the nurse call slave unit and the caution state generation signal, and transmits the captured image of the camera to the mobile terminal. It has a communication control means to be used.

On the other hand, in terms of safety confirmation, a single person living alone is the same as the person requiring nursing care, and is a person to be monitored.

By the way, in the practice of nursing and long-term care, for example, at the time of meals and recreation, a supervisor such as a nurse usually places a plurality of monitored persons such as a nurse required in a predetermined place (dining room or recreation). In some cases, they may be taken to the recreation room, etc. in order to prepare for the move. In such a case, in the nurse call system disclosed in Patent Document 1, the state of the monitored person can be visually recognized by the notification of the caution state generation signal and the video, so that each monitored person prepares for movement. It is also possible to improve work efficiency. However, in the nurse call system disclosed in Patent Document 1, if a caution state occurs, the caution state generation signal is notified to the mobile terminal (an example of the terminal device) regardless of the patient (an example of the monitored person). To. Therefore, in the above case, the observer also receives the notification of the attention state generation signal to the monitored person excluding his / her responsibility, the notification of the caution state generation signal to the monitored person spatially far from his / her position, and the like. , It is not possible to take the monitored person who is ready to move smoothly (smoothly), and in the end, it becomes difficult to improve work efficiency. Of course, other observers respond to the notification of the attention state generation signal to the monitored person excluding the person in charge of the self, the notification of the caution state generation signal to the monitored person spatially far from the own position, and the like. ..

The second threshold Th2 for identifying whether or not it is the size of the head in the standing posture in the living room RM excluding the above, and the size of the head in the lying posture in the living room RM excluding the area where the bedding BD is located. A third threshold Th3 for identifying whether or not the data is the same is stored in the SU storage unit 16 in advance as one of the various predetermined data. Then, the behavior detection processing unit 142 extracts a moving object region from the target image as a region of the person of the monitored person Ob by, for example, the background subtraction method or the frame subtraction method, and from the extracted moving object region, for example, a circular or elliptical hough The head region of the monitored person Ob is extracted by transformation, for example, by pattern matching using a prepared head model, or by, for example, a neural network trained for head detection, and the extracted head is extracted. Detects getting up, getting out of bed, falling and falling from the position and size of. For example, in the behavior detection processing unit, the position of the extracted head is within the location region of the bedding BD, and the size of the extracted head is determined from the size of the lying posture by using the first threshold Th1. When the size of the sitting posture changes with time, it is determined that the person has woken up, and the wake-up is detected. For example, in the behavior detection processing unit 142, when the position of the extracted head changes with time from the inside of the bedding BD location area to the outside of the bedding location area, the size of the extracted head is the second size. When the time changes from a certain size to the size of the standing posture by using the threshold value Th2, it is determined that the person has left the bed, and the person has left the bed. For example, in the behavior detection processing unit 142, when the position of the extracted head changes from the inside of the location area of the bedding BD to the outside of the location area of the bedding BD, the size of the extracted head is the first. When the time changes from a certain size to the size of the lying posture by using the three threshold value Th3, it is determined that the person has fallen, and the fall is detected. For example, in the behavior detection processing unit 142, the position of the extracted head is in the living room RM excluding the area where the bedding BD is located, and the size of the extracted head uses the third threshold value Th3. When the time changes from the size to the size of the lying posture, it is determined that the person has fallen, and the fall is detected.
