[0002] The existing elderly care methods mainly include community elderly care, professional institutional elderly care, and home elderly care. The scale of supporting facilities for community elderly care and professional institutional elderly care is limited, and many elderly people will choose home elderly care. However, home elderly care has the problem of high nursing costs, and it is difficult for the elderly's family members to fully monitor the elderly. When the elderly are alone at home, there may be emergencies such as sudden falls. If they are not discovered and handled in time, they may cause danger. Therefore, it is necessary to fully monitor the behavior of the elderly at home.
[0003] In the prior art, wearable devices are usually used to detect the behavior and health status of the elderly. The location of the elderly is determined by the location signal of the elderly uploaded by the wearable device. However, the device cannot make specific judgments on, for example, the elderly's cooking behavior, toileting behavior, etc. In addition, there are currently some elderly people who feel uncomfortable with or are not used to wearing wearable devices, and the behavior of these elderly people cannot be effectively monitored.
[0004] In addition, the existing technology also uses video cameras installed in the house to monitor the behavior of the elderly in real time, which can effectively detect the elderly's cooking behavior, sleeping behavior, etc. However, the collection and uploading of images of the elderly by video cameras will affect the elderly's personal privacy. For example, toilet behavior, etc. cannot be effectively detected. [Contents of the utility model]
[0005] In order to solve the problems in the prior art of home-based elderly care that the elderly's home behaviors cannot be effectively detected and the elderly's privacy is easily violated, the utility model provides an indoor space retention and behavior recognition system.
[0006] The utility model is realized by the following technical scheme, and provides a system for indoor space retention and behavior recognition, and the technical scheme is:
[0007] A system for indoor space retention and behavior recognition, characterized in that it includes: a personnel activity detection device, a sleep detector, a toilet tank water level detection device and / or a toilet vibration detection device, a smart socket, a refrigerator door opening and closing detection device and a gateway; the personnel activity detection device is installed on the wall or roof ceiling of each space in the whole house, and the personnel activity detection device uses a wireless infrared sensor; the sleep detector is a sleep belt, which is laid horizontally on the chest position of the guardian after lying down; the refrigerator door opening and closing detection device is used to assist in judging cooking behavior; the toilet tank water level detection device is installed in the toilet tank, and the toilet vibration detection device is installed on the corrugated pipe of the toilet; the smart socket is arranged in the kitchen, at least one is arranged and the type of kitchen appliances for cooking connected is indicated, and the gateway is communicatively connected to the personnel activity detection device, the sleep detector, the toilet tank water level detection device and / or the toilet vibration detection device, and the refrigerator door opening and closing detection device, and is communicatively connected to a remote centralized processor.
[0008] Furthermore, it also includes a door magnetic opening and closing sensor, which is installed at the room door position in the whole house.

[0009] Furthermore, the gateway is used to carry a data reporting module and an edge computing center module.
[0010] Furthermore, it also includes a toilet lid opening and closing sensor.
[0011] Furthermore, the gateway adopts an IOT gateway.
[0012] The beneficial effects are:
[0013] The indoor space retention and behavior recognition system can comprehensively identify and monitor the behavior of the elderly. With the help of the personnel activity detection device, the room location of the person can be effectively detected, and the time the person stays in the room can be recorded. If the elderly stay in the room for too long, an alarm can be issued to avoid safety accidents and ensure the safety of the elderly living alone. The personnel activity detection device uses infrared sensors to protect the privacy of the elderly. The sleep detector on the bed can effectively detect the bed status and sleep conditions of the elderly, and record the bed time of the elderly to avoid the personnel activity detection device from misreporting the elderly's bed behavior. With the help of the toilet tank water level detection device, the toilet behavior of the elderly can be recorded according to the changes in the toilet water level. In combination with the recorded toilet time and whether there is bed resting behavior before going to the toilet, the behavior and number of getting up at night can be recorded to comprehensively monitor the health of the elderly. With the help of smart sockets and refrigerator door opening and closing sensors, the cooking behavior and cooking time of the elderly can be effectively monitored. With the help of this indoor space retention and behavior recognition system, the elderly do not need to wear related equipment, which is not easy to detect and will not affect their daily life. At the same time, the risk of privacy and security leakage is low. The storage and analysis of the elderly's behavior data and physical condition data also helps to comprehensively analyze and warn the elderly's physical health. In addition, setting up a toilet lid opening and closing sensor can further improve the accuracy and effectiveness of toilet behavior judgment.

[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings.
[0017] Specific embodiment 1 of the indoor space retention and behavior recognition system provided by the utility model:
[0018] This embodiment provides a system for indoor space retention and behavior recognition, such as Figure 1 , including a personnel activity detection device, a sleep detector, a toilet tank water level detection device or a toilet vibration detection device, a smart socket, a refrigerator door opening and closing detection device and a gateway.
[0019] The personnel activity detection device is installed on the wall or roof ceiling of each room in the house. At least one is installed in each room. When performing detection, a scanning cone is formed. When installed, the space area should be covered as much as possible, and it should not be affected by the opening and closing of doors to prevent the door from affecting the detection range. In this embodiment, the personnel activity detection device uses a wireless infrared sensor, which is a low-power device. When performing detection, it only detects the movement of the target, which can better ensure the privacy and safety of people in the house.
[0020] The sleep detector is used to detect the bed-lying status of a person. In this embodiment, the sleep detector is a sleep belt, which is laid horizontally at the chest position of the monitored person after the person lies down, that is, on the bed and placed at the chest position of the person to supplement the blind area of the infrared device.
[0021] The toilet tank water level detection device or toilet vibration detection device is used to detect the use of the toilet. The toilet tank water level detection device is a float valve type water level detection device, which is installed in the toilet tank. By detecting the change of the water level in the toilet tank, the use of the toilet is judged. When the water level in the toilet tank drops once, it is judged that the person has used the toilet once. When using the toilet vibration detection device, the toilet vibration detection device is fixedly installed on the toilet bellows, and the person's use of the toilet is judged by the vibration of the water pipe.
[0022] The smart socket is set in the kitchen, and at least one smart socket is set and the type of connected kitchen appliances is indicated to detect the power consumption of kitchen appliances. In this embodiment, there are 5 smart sockets, namely, a socket for a range hood, a socket for an electric rice cooker, a socket for an oven, a socket for an induction cooker, and a socket for a microwave oven. In other embodiments, other numbers of smart sockets can be set, which are determined according to the actual types and numbers of kitchen appliances, for example, a socket for a dishwasher, etc.
[0023] The refrigerator door opening and closing detection device is used to assist in judging cooking behavior. In this embodiment, the refrigerator door opening and closing detection device adopts a door magnetic sensor.
[0024] The personnel activity detection device, sleep detector, toilet tank water level detection device or toilet vibration detection device, smart socket and refrigerator door opening and closing detection device are all communicatively connected to the gateway, and the gateway is communicatively connected to the remote centralized processor. Through the gateway, the detection signal can be processed according to the actual installed software system, and spatial retention and behavior recognition can be performed. In this embodiment, the gateway is used to carry a data reporting module, and the received detection signal is uploaded to the remote centralized processor through the data reporting module. The remote centralized processor then performs spatial retention and behavior recognition, and then sends the judgment result to the user end. The remote centralized processor registers the corresponding installation points of the personnel activity detection device, sleep detector, toilet tank water level detection device or toilet vibration detection device, each smart socket and refrigerator door opening and closing detection device, so as to ensure the judgment of the corresponding device signals in different rooms. Figure 1 ,The gateway is deployed in the living room and uses an IOT gateway.
[0025] In other embodiments, the gateway is used to carry a data reporting module and an edge computing center module. When the gateway receives a detection signal, it immediately performs signal processing through the internal edge computing center module to complete spatial retention and behavior recognition, and then uploads the result to a remote centralized processor, which then sends the judgment result to the user end.
[0026] The indoor space retention and behavior recognition system also includes a door magnetic opening and closing sensor. In this embodiment, two door magnetic opening and closing sensors are provided, one installed at the toilet door and the other installed at the kitchen door, which are used to assist in judging the toilet behavior and cooking behavior of people respectively. For the door of the rotary switch, one end of the door magnetic opening and closing sensor is installed on the room door away from the door axis, and the other end is installed on the corresponding door frame position. For the sliding door, one end of the door magnetic opening and closing sensor is set on the anti-collision door frame, and the other end is set on the side of the corresponding sliding door. In other embodiments, the door magnetic opening and closing sensor may not be set, or the door magnetic opening and closing sensor may be set on each room door in the whole house.
[0027] When performing human behavior detention detection, if the human activity detection device in the corresponding room detects the trajectory of human activity, it will send the human activity trajectory signal to the gateway, record the duration of the human activity in the room, and send the corresponding duration signal to the gateway. The gateway obtains the human detention position and detention duration based on the human activity trajectory signal and the human activity duration signal, and sends the signal to the remote centralized processor. The remote centralized processor stores the general detention duration of the elderly in the corresponding room, and sends the general detention duration to the remote processing center through the gateway, and updates the set detention timeout alarm duration.
[0028] When the human activity detection device does not detect any human activity, if the gateway receives the upload signal from the sleep detector, it will determine that the person in the room is lying in bed. The sleep sensor can be used to detect the person's lying in bed behavior and sleep quality.
[0029] When the personnel activity detection device located in the toilet detects the trajectory of personnel activities, and the toilet flushing detection device or the toilet vibration detection device detects the use of the toilet, the toilet use signal is sent to the gateway, and the gateway determines that the personnel behavior is toilet use, and controls the timeout time to record the toilet use time, and divides the urination and defecation behaviors according to the detected toilet use time. If the toilet use behavior occurs at night, it is determined as a nighttime behavior. The night time can be set and adjusted according to the sleep time of the personnel.
[0030] When the smart socket in the kitchen detects that the kitchen appliances are powered on, that is, when the kitchen appliances are using electricity, the kitchen appliance power usage signal is sent to the gateway. The gateway identifies the type of electrical appliances and determines the cooking behavior. When it is detected that the kitchen appliances are used continuously for more than 20 seconds, it is determined that cooking behavior has occurred. If there are other cooking behaviors within a set time period before a cooking behavior, for example, within 30 minutes, the two cooking behaviors are combined and recorded as one cooking behavior.
