Design And Implementation Of Human Health Security Monitoring System Based On Smart Watch

Security monitoring issues have always been one of the most discussed topics.Traditional security monitoring research work is mainly for environmental security.It has great advantages in video surveillance,GPS positioning,face recognition,and NFC radio frequency identification.But since ancient times,the main focus of security monitoring is the safety of human life,health and property.The traditional security monitoring system does not have the ability to monitor the characteristics of human health.Therefore,the security monitoring system with human health monitoring as the security object has great research value.The main object of the security monitoring system based on human health monitoring(hereinafter referred to as the human health security system)is human health and safety,and the objects of the human health security system are also very mobile,and the human body cannot wear too much Heavy and huge security monitoring device.This has brought great problems to the research of human health and security systems.In order to solve the above problems,this paper designs a set of human health and security monitoring system based on the hardware of smart watch.The system takes the monitoring of human health characteristics as the main body,and optimizes and improves the positioning algorithm in the traditional security monitoring system.The main research work of this paper is as follows:(1)Aiming at the shortcomings of traditional security monitoring systems that do not have human health monitoring,this paper starts research from human health monitoring technology,focusing on the detection algorithm principles of characteristic parameters such as heart rate,blood oxygen,body temperature,and exercise step counters in the human body.Combined with the analysis of actual scene application requirements of Chinese chemical companies in Jiangxi Province,the implementation plan of the security monitoring system with human health monitoring as the main body was determined.The system is divided into two sub-systems based on multi-level and low-coupling ideas.The main body is the human health monitoring sub-system to realize health monitoring,and the security positioning sub-system is supplemented to realize the emergency positioning and tracking function.In order to meet the long-distance networking needs of factories and enterprises,the system uses NB-IOT communication technology as the main communication method to reduce the network construction cost of traditional security monitoring systems.The system can provide large factories and enterprises with solutions to employee health and safety supervision issues,especially in response to emergencies similar to the new crown epidemic,which has good advantages.(2)Aiming at the problem of high cost and low flexibility of traditional security monitoring system.By studying the application technology of wearable devices,a human health security monitoring device based on smart watches is designed to achieve the "movable" and "wearable" goals of the security monitoring device,and reduce the traditional security The construction cost of the monitoring system.At the same time,in order to reduce the weight and volume of the human health and security monitoring device,this article uses a multilayer PCB design on the hardware circuit to reduce the size of the device as much as possible.The software is constructed by transplanting the TI-RTOS real-time operating system to integrate the underlying Bluetooth protocol.The stack is separated from the feature sensor detection mechanism,and a multi-core communication mechanism is constructed,which not only improves the data processing speed,but also reduces the power consumption of the system.(3)Aiming at the problem that the GPS positioning mechanism in traditional security monitoring devices cannot be used in an indoor environment.Based on the requirements of position positioning in the personal health security system and the actual indoor environment,this paper comprehensively analyzes the advantages and disadvantages of various positioning algorithms based on RSSI,and designs a three-side ranging positioning algorithm based on RSSI.On the premise of three Beacon nodes in the traditional three-side ranging positioning algorithm,Without any increase in high cost and complexity of cases,more than just adding a Beacon Beacon nodes,and by building the mathematical model of multiple round node form to improve the positioning performance of traditional RSSI ranging localization algorithm,at the same time,in a real scenario bluetooth signal is easily affected by external environment,to reduce the interference signal,and compensate the data using the partial least squares.The actual test shows that the optimization and improvement scheme based on the traditional RSSI trilateral ranging algorithm improves the positioning accuracy by about 20%,and the complexity and cost of the system do not increase,which is more convenient for the actual deployment of users.In summary,the smart watch-based human health security monitoring system designed in this article for the needs of human health security monitoring not only solves the limitation of traditional corporate security monitoring systems that cannot monitor the health of employees,but also proposes for the field of human health security monitoring A set of efficient and feasible solutions is established.The system has extraordinary reference significance for the development of wearable medical equipment and human health and security monitoring,and has great application prospects.
