How can the silent elderly be heard? This community uses "inconspicuous" equipment to do "life-saving" things. Equipment | Intelligence | Community
Recently, Mrs. Wang, an 87 year old elderly person living alone on the Bund Street, is looking forward to the upcoming renovation of her Shanbei community. A new surveillance camera has been added to the internal roads of the community, equipped with intelligent wrestling detection and alarm functions, which will make the elderly and children in the community more comfortable to play; In the public areas of residential corridors, there are all kinds of IoT sensing devices available, such as smoke detectors, gas detectors, temperature and humidity sensors, and water pressure sensors. No matter which corner of the building has an abnormal situation, it can be accurately located immediately, and a dedicated person can come to the door to prescribe the right medicine to solve the problem; Further refinement was carried out to Grandma Wang's own home, and a new door magnet was installed on the entrance door. Behind the water meter of the water company on the left side of the door, a brand new intelligent water detection device has also been equipped.
Starting from April this year, the Urban Transportation Center of the Bund Street has introduced the "minimum management unit" digital governance model into the Shanbei community, piloting the construction of a "smart community". It will soon be officially put into use, providing diversified services and guarantees for the care and daily management of special groups in the neighborhood through information technology and artificial intelligence technology.
Digital twin extension community perception tentacles
Shanbei District was built in the 1980 s and is located between the two urban public spaces of Suzhou River Waterfront Space and Nanjing Road Pedestrian Street. There are many elderly groups here, the degree of aging is high, and the double "aging" is superimposed, so that special groups and community care have become the key starting point to improve community fine management and community governance.
In the smallest governance unit of the city, the "community", big data IoT technology and digital twins make management more refined. Xu Yunu, a staff member of the Urban Transportation Center in the Bund Street, introduced that the Shanbei Community has completed the construction of the Internet of Things perception system, AI visual scene, and the smallest management unit screen. Among them, the intelligent large screen gathers most of the information about data, making it convenient to find people with just one click. Shanbei Community has also docked with the relevant population database to import the registered residence population and resident population data in the community. The "Community Overview" column on the big screen clearly shows the total population, registered residence population and number of houses in the community, which can help the neighborhood committee to more accurately and efficiently obtain the flow of people in the community and achieve "housing management".
On the big screen, the most crucial thing is still the "white model" of Shanbei Community. Xu Yunu told reporters that by installing IoT sensing devices in public spaces within the community and buildings, all events, buildings, road facilities, etc. in the Shanbei community can be modeled, making it a virtual image of the digital world. On the basis of static modeling, multi-dimensional real-time dynamic data can be superimposed to achieve real-time prediction and discovery of community management.
With the help of this data information, street, neighborhood committee, property management and other management parties can have a more intuitive perception and management of the internal facilities and each building in the community from the perspective of the living organism. After the problems appear, it also shortens the link and time cost of troubleshooting, making problem-solving more efficient.
Xu Yunu gave an example that if the smoke detection system on the third floor of Building 1 in Shanbei Community triggers an alarm, the relevant management personnel can quickly locate the specific location of the problem inside the community building and promptly come to the door for disposal based on the warning signal that lights up at the corresponding point on the large screen "white model".
"By using digital twin technology to simulate and generate a 'white model', it can not only help management personnel more efficiently obtain dynamic elements of community management such as personnel entry and exit, fire hazards, and special personnel care, but also improve the data collection and problem discovery capabilities of minimum unit management, achieve automatic event detection and reporting, and improve the efficiency of solving and handling."
The construction of a unified digital governance base has gathered data from various IoT perception devices, which will comprehensively extend the perception tentacles of the Shanbei community. Within the smallest governance unit in the city, the management unit will be connected to form a surface.
Big data speaks for the "silent" elderly
According to the survey data of the Bund Street in the early stage, in Shanbei District, there are 10 households with 10 people living alone and elderly families over 80 years old, and 54 households with 108 people living alone and elderly families over 60 years old and under 80 years old. At present, in addition to the unified installation of Internet of Things sensing equipment in public areas, the Street Urban Transportation Center, on the basis of residents' willingness, provides more detailed installation of home management equipment, including door magnetism and intelligent water detection, for the elderly, lonely and pure old families in the community.
These two devices are not big, and they are even somewhat inconspicuous when installed behind the entrance door and water meter; But in critical moments, it can save lives. For elderly people living alone and pure elderly families, real-time updated intelligent water detection is a signal of normal home life. For example, in case an elderly person falls or falls unconscious at home without water for a long time, or experiences a sudden illness and fainting while taking a shower, resulting in a surge in water consumption in a short period of time, anomalies reflected in the real-time data of intelligent water detection can help these "silent" elderly people speak up and become a signal for them to seek help from the neighborhood committee and the street.
Xu Yunu told reporters that due to limited manpower, the neighborhood committee has objective difficulties in achieving comprehensive daily management and care for elderly people living alone and widowed in the community. However, data transmitted through door magnets and intelligent water detection can assist neighborhood committee officials in providing more targeted care for the elderly in need, avoiding accidents.
The reporter noticed on site that although it is a household management, the relevant equipment is still installed outdoors. "Elderly people do not feel overly excluded due to being 'monitored', which helps the neighborhood committee to better grasp their home safety status while maintaining a sense of boundaries," said Xu Yunu.
