The Internet of Medical Things has developed rapidly as an important direction in the field of Internet of Things, especially through the use of the new generation of information technology, theoretical and applied research on medical IoT intelligent health management that provides “full-service.” It has become a research hotspot of many universities and research institutions. Therefore, conducting research on intelligent health management in the network of medical things is of great engineering importance and theoretical guidance to improve the level of medical information. For health management in the network of medical things to conduct research around the goal of health management “Everything full spectrum for everyone,” analyzed the lack of sharing of health information in current health management, lack of continuous monitoring and management of health indicators, etc., a new “individual-family-community-hospital” four-level intelligent health management service model is proposed, the hardware architecture of intelligent healthcare management and the software maintenance system have been built. Through methods such as real-time multi-source data collection, mobile sensing, cloud computing, multi-network fusion technology, continuous monitoring and intelligent management of health data is realized convenient, fast and efficient. It solves the problems that the existing medical system cannot meet the multi-level health needs, personal data security and privacy protection, etc., it has achieved the goal of real-time interactive health management of regionalization, multi-level and multi-center, and whole-person, whole-process and all-round.

In recent years, when the living standard of the population is constantly rising, people pay more and more attention to physical health, but this is accompanied by an aging trend of the population within the country. ere are more and more elderly people suffering from diabetes, hypertension, cardiovascular and cerebrovascular diseases. e proportion of chronic diseases is increasing, at the same time, the fast pace of life in modern society, high work pressure, mental stress, unhealthy lifestyle and obesity and other factors, among the young and middle-aged population, the number of chronic disease patients is also increasing, and the average age is decreasing. It is reported that there are currently about 300 million hypertensive patients in 2020 in China and this number is still growing. Chronic diseases have become the number one killer of urban populations [1] . On the other hand, due to the uneven distribution of medical resources, there are urban-rural differences and regional differences. In addition, there is still a gap between the proportion of medical resources and developed regions in foreign countries. At the same time, there is also a lack of informatization means to achieve hospital interoperability and health file sharing. e masses are often faced with repeated inspections, repeated payments, repeated diagnosis, etc. It wastes medical resources and patients' human and financial costs, and leads to extremely tense doctor-patient relationships. At present, people with various medical and health service needs such as patients, recovered people, healthy, subhealthy, and high-risk groups are flocking to the hospital, this leads to the shortage of clinical diagnosis and treatment service resources and the difficulty of seeing a doctor. However, public health resources such as disease management services and health management services are idle [2] .

is is not to say that it can be solved by increasing the investment in clinical diagnosis and treatment service resources. What is needed is to change the old model of health care delivery and to provide targeted medical and health services for different groups of people. rough the innovation of service model, it can relieve resource shortage and improve service quality; Effectively provide all-weather, long-term deep-level health services for healthy, subhealthy and sick patients, it can truly realize the health protection service of "everyone has a doctor," Figure 1 shows the structure of the hospital information system [3] .

Dimitrov, D. V. et al. stated that the concept of the Internet of ings was put forward in 1999, and the Internet of ings is the Internet associated with things, the abbreviated name is the: IoT. Information sensing devices, such as radio frequency identification (RFID), infrared sensors, GPS and others, connect any object to the Internet by agreement, exchange information and communicate in order to implement a network of intelligent identification, localization, tracking, monitoring and managing an object [4] . Sharma et al. think this means two levels: firstly, the core and foundation of the Internet of things is still the Internet and is an extended and expanded network based on the Internet. Secondly, his client is lengthened and extended to any subjects and objects for information exchange and communication [5] . Deursen and others stated that the Internet of ings is a network based on information carriers such as the Internet, traditional telecommunications networks that allow interconnection of all ordinary physical objects that have independent addressing. e Internet of ings not only provides the connection of sensors, but also has the ability of intelligent processing, which can implement intelligent control of objects [6] . Chen and Huang stated that e Internet of ings combines sensors and intelligent processing to expand the scope of their application through various intelligent technologies such as cloud computing, pattern recognition. Analysis, processing, and processing of useful data from the massive information received by sensors, taking into account the different needs of different users [7] . Pauzi and Juhari believe that the Internet of ings is being fully applied in various industries through the application of new technologies such as Radio Frequency Identification (RFID) technology, sensor technology, nanotechnology, fully connecting various objects, and through the wireless network, etc., various real-time dynamic information collected will be sent to the computing processing center, aggregate, analyze and process, Can realize centralized management, control of machine, equipment, personnel through the central computer, and optimize production and life in a more subtle and dynamic way, achieve the organic integration and harmonious coexistence of human society and the material world [8] . Ji, H. et al. stated that the initial design idea of applying the Internet of ings technology in the medical field is mobile medical care, and the realization of mobile medical care requires mobile computing and intelligent identification. From the boom of mobile medicine that has been observed in the medical industry after 2004, the change in management perceptions, the transition from business systems to object management, is also central to mobile medicine, which is also the first driving force of the Internet of things. Very important ideas have been put forward in the field of research and application of the Internet of Medical ings, and all systems should be focused on specific objects [9] . Nwogbaga, N. E. et al. stated that the most important objects in the medical industry are patients, around which are doctors, nurses, medicines, devices, all patient-related systems, and if the orderly management of these systems in accordance with certain management standards and rules has the main effect: all objects pass in an orderly and work under control, thus ensuring basic medical safety, the quality of hospitals [10] . Al-Malah, A. R. and others believe that mobile medical health service is a service method based on the telemedicine system. At present, due to insufficient and uneven distribution of medical resources, as a result, the basic health needs of most people in the world cannot be met. At the same time, high medical expenses and complicated diagnosis and treatment procedures also bring a lot of inconvenience to patients. e cycle of training medical personnel is very long. It is impossible to meet the growth rate of people's demand for medical resources, but mobile medicine can solve these problems very well [11] . Tatan, M. et al. stated that doctors provide online services through traditional Internet or mobile Internet, and patients can choose a doctor only through a professional self-service terminal, and by uploading diagnostic results, interacting with diagnostic information, providing dynamic or static images, etc, provide doctors with disease characteristics, realize cross-regional diagnosis and treatment, and are not limited by time and place [12] . Sun et al. believe that medical informatization is an effective way to fundamentally solve high medical costs, lack of medical resources and uneven distribution. It will become an inevitable direction for the development of medical care in the future. Developed countries can effectively reduce medical costs through mobile health care, and improve service quality. In developing countries, mobile health care is used to solve the problems of lack of medical resources and uneven distribution [13] .

According to the previous analysis and the practice of the new business cloud platform, the plan is based on cloud computing technology, build a cloud computing-based IoT operation platform. It mainly includes the following parts.

Considering that the cloud platform must support the development and use of business, in addition to meeting the bearing requirements of the design, 30% of the resource capacity needs to be reserved, for future business development needs [14] . e construction of cloud-based resource pools mainly considers hosts (PC servers and blade servers, minicomputers), storage (FC-SAN, NAS) and network virtualization solutions, at the same time consider backup, security and other needs. rough the unified management system, the intelligent configuration and life cycle management of all resources are realized. Platform database, hosted on the AIX environment application physical machine resource pool, other types of application servers (application, WEB, management, interface, SMS, MMS, WAP server, etc.), all run uniformly in the virtual machine resource pool [15] . High-performance storage, mainly used for storage of databases, key business data, etc, using storage virtualization software, it can realize unified management and distribution of storage in heterogeneous environment; because this part of the data is more important, it can be backed up by configuring a small tape library (10T).

e resource pool management platform can realize the unified management of all resource pools. Specifically, it should have the characteristics of automatic management, real-time monitoring, support for both physical and virtual devices, support for massive nodes, high availability and high scalability [16] .

(1) Presentation Layer. e presentation layer is mainly responsible for portal presentation and external service interface provision. Portal is divided into administrator portal and application provider portal, admins through the Admin Portal, manage and monitor all resources and services of the entire system, check the load of the entire system, understand the expansion and contraction status of each component in the system, and when an abnormal alarm occurs, you can view the location of the problem and assist in locating the problem [17] .

(2) Management. e management layer is the core of the management platform management system, it should have various functions such as alarms, logs, performance statistics, deployment, automatic scaling control, configuration, resource and device management, and service management [17] . To improve the deployment options, performance and reliability of the system, EDA event-driven architecture should be adopted within the management, run each event reported by the domain, through the EDA event bus, it is passed to the home service for processing. rough the use of the event mechanism, the system concurrency efficiency and throughput rate are improved.

(3) Communication Layer. e link layer is responsible for managing the link between the domain as a whole and the execution domain. e communication layer should provide a variety of communication means, including message queues, socket communication nodes, ftp/tfip communication nodes, etc. [18] . For communication of different quality attributes, different communication methods can be used for communication. For example, log information passes through the log aggregation node, transfer logs to a distributed file system, monitoring information and deployment commands issued by the management layer are transmitted through message queues. e transport layer should consider its own expansion in the design, and can adapt to the transmission requirements of large amounts of data.

(4) Domain Controller. Massive service nodes can be managed by dividing them into multiple domains. Each domain can contain compute, storage, and networking equipment. e computing device can be a blade server, a rack server, etc., storage devices include SAN, NAS, etc., network devices include switches, routers, load balancers, and firewalls [19] . Each domain is based on business needs, its hardware and software configuration can be focused. For example, a domain needs to provide external distributed memory caching services, a blade server with a relatively large amount of memory can be used, the requirements for storage devices are not high; some need to provide external storage services like amazon S3, it requires that its storage capacity must be sufficient. One domain controller is deployed inside each domain, it is used to manage the hardware and software resources within the domain. For example, domain controllers provide device management functions as well as dhcp services and tftp services, ability to manage automatic discovery of devices, and handles the automatic deployment of the operating system on a single board [20] . In addition, the domain controller is responsible for receiving commands from the management platform management layer, and forward these commands to the management agent of the corresponding node for execution.

(5) Management Agent. e management agent is deployed on each business node, for business nodes that provide external services in the form of physical machines, the management agent is directly deployed on the operating system of the physical machine; For business nodes that provide external services in the form of virtual machines, management agents are deployed on both the host machine and the virtual machine. e main responsibility of the management agent is to monitor the hardware and software resources of the business node, and execute various commands issued by the management, such as downloading software packages, installing software, starting specified software and so on. e management agent adopts an extensible plug-in architecture, different software and hardware can develop corresponding plug-ins and deploy them on the management agent, in order to complete the monitoring and management of software and hardware [21] . e management platform also needs to implement two views of resources and business, open different views for different user roles, in order to achieve decentralized management of resources.

is design mainly uses the existing internal application system resource pool and virtualization platform, build a cloud computing operation management platform on it, and divide virtual machines to carry the mobile medical and health service system, at the same time, business processes such as CRM, BOSS, and medical institution HIS are opened up, highlighting the automation of cloud computing business processes, and adopt the first-level BOSS interface specification to enhance system adaptability. As shown in Figure 2 :

At present, two mobile internal application system platforms have been formed, which are virtualized computing resource pools and storage resource pools based on VM Ware and Hyper-V, respectively, the system scale of the computing resource pool is 58 blades on the host, 944 total cores, it can provide 200 virtual machines, and the storage resource pool system scale is 9 pieces of storage, which can provide a total effective capacity of 154T. Considering that the initial carrying target of the mobile medical and health service system is 50,000 registered users, 1500 concurrent users, and save the user's physical data and related advice materials for 3 years, as well as resources such as expert database, a total of 15 virtual machines are used, 55T storage resources are used, and 22 external network IP addresses are used [22] .

e internal modules of the system mainly include: hospital IT system, support system, medical terminal, data storage, calculation and analysis are performed on the cloud platform. e interfaces between the internal modules of these systems are shown in Figure 3 : e interface protocol table of regional health information system is shown in Table 1 :

Guard System and Peripheral Subsystem. As the entire mobile medical and health service system, sensors, gateways and platforms follow WHIP-S and WHIP-T protocols, its interface is shown in Figure 4 [23] :

As can be seen from the figure, there are three devices between the user and the healthcare provider: sensor terminals, gateway terminals, and business platforms. e sensor terminal is used to measure physiological indicators, such as blood pressure, electrocardiogram, blood oxygen saturation, heart rate and other physiological indicators; e gateway terminal is used to link the sensor terminal to receive physiological indicators, and forward it to the business platform; the gateway is also used to receive health information and other instructions sent by the server [24] .

As can be seen from Figure 5 , there are two forms of T interface: long-distance wireless communication, including: GSM, GPRS, EDGE, TDS-CDMA, long-distance wired communication, including: ADSL, PON.

ere are two forms of S interface: short-distance wireless communication, including WIFI, Bluetooth, Zigbee, etc., and short-distance wired communication, including serial port, USB, Category 5 cable, etc. [25] .

e platform hardware is implemented as follows:

(1) After individual users measure health physiological indicators with health medical terminals, the measured data will pass through the gateway terminal, it

Terminal Server S Interface T Interface is sent to the health guard service terminal access and distribution server, so as to be further sent to the health service server. (2) Peripheral systems such as hospital IT systems, call centers, and mobile health service guardian platforms, the interface is connected through the health guard service interface machine. Considering the security of the hospital IT system, the interface machine and the hospital IT system should be connected by a dedicated line.

Portal WEB server through the Internet to provide/ obtain services, the mobile health guard service server is providing background data information and processing. (4) As the core of the entire business platform, the mobile health guardian business server provides the following functions: unified health business platform process support; system operation management and maintenance of the entire platform; management of medical and health institutions; management of individual users and packages. (5) Realize the interface with auxiliary systems such as M2M platform, health expert system, BOSS, GIS, etc. (6) e entire platform can be maintained and managed through the management terminal PC. (7) In the management of health and medical terminals, the participation of a general M2M platform can reduce the burden of health service servers [26] .

Hardware. Figure 6 is the hardware principle block diagram of the gateway designed by the author. e gateway collects the data measured by the sensor through the "short-distance communication submodule." en through the "long-distance communication submodule," the functions of each subsystem of the collected measurement data gateway are described as follows:

(1) Short-range communication subsystem: link sensors for data interaction and transmission. Wired interfaces such as serial port, USB, and Category 5 cable can be used, and wireless interfaces such as Bluetooth, Zigbee, and Wif can also be used. From the above analysis of the gateway terminal, it can be seen that, as the most frequently used and convenient terminal in modern mobile communication, smart phone, in recent years, it has faster and faster communication capabilities, higher and higher data processing capabilities, and more and more convenient human-computer interaction capabilities, it is very suitable as a gateway terminal for mobile health care services, can choose the mainstream smartphone platform in the market, development of customized smartphone gateway terminal software.

e simulation results are shown in Figure 7 : after the oximeter is paired with the Bluetooth of the Android mobile phone, it starts to record the blood oxygen and pulse information of the test subject, the SPO2 and Pulse values, and the real-time graph of blood oxygen are represented by a line graph. e mobile phone is connected to the community service center or the home health management terminal through Wifi, after the connection is successful, the data information collected by the oximeter can be monitored in real time.

rough the research on key technologies such as the integration of TD and Internet of ings technologies, the unified access of diversified terminals, and the research on standardized platforms, completed the design and implementation of the cloud platform-based mobile medical health service system. Firstly, cloud platformbased mobile medical and health service system, it can carry services that meet the actual needs of users, such as chronic disease management and personal protection for special groups, and can be connected with the hospital IT system, so that the collected health-related information can play the greatest role. It is convenient for users to carry out diagnosis and treatment. Secondly, the interface between the cloud-based mobile medical and health service system platform and other systems is standardized (such as with HIS, short message center, terminal business data, etc.), make the interface universal, the system has good scalability. Once again, a mobile healthcare platform implemented on a cloud platform can simplify the complexity of the business platform itself and reduce the cost of building a healthcare platform. Finally, the mobile health system platform integrates several resources, such as health terminals, communication networks, M2M platforms, medical healthcare institutions and telecom operators, it is conducive to enhancing the influence of the health protection business industry chain.

e Cloud Platform Mobile Health Care System integrates TD and ION technologies, providing a platform for two-way user and healthcare management choice, coupled with new trends in healthcare management. By accurately grasping customer needs and taking health as the entry point, the large system has achieved the ability to seize customers' share of information life. From the overall strategy point of view, the system has low price, simple operation and large demand, and by gradually enriching the application content, on the basis of accelerating the construction of the commercial platform, adopt support mode, support network-wide business operations.
