1. System significance
1. The elderly seek help in emergencies, enter the dangerous area, take the initiative to warn, solve the lagging problem of the incident, expose the hidden danger of the incident in advance, and avoid the incident;
2. The scene of the incident is reproduced, and the Internet of Things skills and the existing video can be linked to view the scene in real time, providing a basis for the deployment of relevant personnel to solve the emergency in time;
3. Reduce the workload of nursing home staff, improve work efficiency, and improve the handling of nursing homes
The level of informatization promotes the institutionalization and standardization of the handling of senior citizens in nursing homes;
4. Real-time development to ensure the safety and stability of senior citizens, laying a solid foundation for the gradual realization of “intelligent all-round supervision” in nursing homes.
2. System architecture and program description
The personnel positioning system for nursing homes is based on the shortcomings of the current nursing home management system in the market. For example, the problem of precise positioning of the old man, the need to locate each room, the unconscious fall of the elderly and the alarm for help, etc., are the most advanced in the world today. A security system developed based on RFID skills, sensing skills, monitoring skills, communication skills, and RTLS real-time positioning skills. It perfectly solves the functional requirements such as automatic personnel entering and exiting judgment processing, precise positioning of personnel, regional positioning processing, and alarm for help when falling. The system can also realize functions such as intelligent monitoring and management, personnel information management, cross-border alarm, button for help alarm, tracking and other functions. The level of safe handling for the elderly has been greatly improved.
2.1 System architecture
2.2 Program description
ChooseRFIDSemi-active skills are used for regional positioning and management of personnel. In each monitored area, such as each room, install low-frequency activators. Each low-frequency activator has 4 or 6 activation antennas, and adjacent 4 or 6 antennas. The room can share a low-frequency activator. In our positioning system, the low-frequency activator antenna is the smallest base point. The tag is activated within the range of 3-3.5 meters from the activator, and its positioning accuracy can be described as 3-3.5 meters. Activators in different areas have their own unique address codes. When a person enters the positioning base station with a semi-active low-frequency activation tag and is activated, the tag works normally, and the ID number of the tag is sent to the outside world, together with the activation tag. The address code of the activator, in this way, through the address code of the activator, we can locate the location of the tag. When the tag is taken from one activator to another location, the uploaded activator address code will also change accordingly, thus forming a complete positioning system. The data uploaded by the tag is received by a large-scale positioning base station gateway, and the information is uploaded to the processing center for processing, completing the entire positioning system.
