Intelligent Aged Care System Based On ARM Cortex-A9

At present,China has entered an aging society,but there are defects and deficiencies in the social old-age security system and old-age service capabilities,which cannot meet the current needs of old-age care.Faced with the growing problem of old-age care,smart old-age care came into being.This paper proposes a Intelligent Aged Care System based on ARM Cortex-A9 through research and analysis of the actual needs of pension,combined with embedded,Internet of Things and intelligent voice technology.The system builds a tree-shaped Zigbee wireless sensor network as a way of indoor data transmission.According to this,the system is divided into two hardware devices: terminal equipment and gateway coordinator.Terminal devices scattered in different places in the room can collect environmental information and execute related instructions,and realize data transmission with the gateway coordinator through the Zigbee sensor network.The gateway coordinator is responsible for processing the data information from the entire network,and uploading data to the OneNET cloud platform through NB-IoT,implementing storage and management data on the cloud and providing an interface for secondary development,which is convenient for expanding the system.In addition,the gateway coordinator transplants the Linux + Qt system to provide an interface for human-computer interaction,and is equipped with the intelligent voice library of iFLYTEK to realize the intelligent voice interaction function.The gateway coordinator can also establish a connection with the blood pressure and heart rate sensor to obtain real-time blood pressure and heart rate data of the elderly,and to a certain extent grasp the physical health of the elderly.This article completes the needs analysis of the Intelligent Aged Care System,the overall scheme design,the design and implementation of the hardware and software,and the final test of the system.This system has rich and more intelligent functions,and has advantages in low power consumption,suitable aging,stability,etc.,and can realize the networking and management of a large number of devices.Good application and market value.
