technical field

The invention belongs to the technical field of medical systems, and relates to an intelligent medical system based on Internet of Things technology.

Health is an important criterion to measure people's quality of life, and it has always been a subject of eternal concern to human beings. With the development of society, the rapid improvement of material living standards, and the continuous advancement of medical technology, many diseases that were previously incurable can also be treated well; Coupled with environmental pollution and other issues brought about by industrial development, they have posed serious challenges to people's health, and many new factors that endanger human health have also emerged one after another, such as cardiovascular disease, coronary heart disease, diabetes, etc., which have been recognized. Listed as the most important diseases endangering human health. These diseases do not occur in a day, but must be caused by people's long-term unhealthy living habits. For these "chronic" diseases, people can prevent and assist them in their own treatment. Therefore, it is necessary to pay attention to and understand the changes of some parameters that can reflect these diseases in real time. Physiological parameters such as blood pressure, blood sugar, body temperature, and electrocardiogram are important vital signs of the human body.

In addition, the upper computer system is also connected with a GSM gateway, which is used to send an alarm to the target contact when it is found that the ward's physical sign data is dangerous and abnormal according to the data analysis results of the upper computer system.

As shown in Figure 2, the GSM gateway includes processor 2, LCD touch screen, memory chip, 3G/4G module, ZigBee module, WiFi network card and wired network card, LCD touch screen, memory chip, 3G/4G module, ZigBee module, WiFi network card and The wired network card communicates bidirectionally with the processor two respectively. Among them, the second processor uses ARM Cortex A9 series chips, specifically Samsung's Exynos 4412 chip, which is responsible for data calculation and control of the entire gateway. The LCD touch screen provides a human-computer interaction interface, and the user can send instructions or view historical data through the LCD screen. The memory chip can cache the historical data of physical signs of all wards in the home environment within a certain period of time. Another function of the gateway is to convert the data packet format of different networks to realize the interconnection of the network and the normal transmission of data packets. Specifically, it includes four aspects of communication modules, namely WiFi network card, wired network card, 3G/4G module, and ZigBee module. In the home environment, all the physical sign data collected and sent by the ward through the general sensor node are aggregated to the ZigBee module. The ZigBee module module sends the obtained physical signs data to the ARM Cortex A9 chip through the serial port. The wired network card and WiFi network card can enable the home gateway to access the Internet, and then pack the human body sign data received by the ZigBee module into TCP/IP data packets and send them to the data storage center for storage and processing through the Internet. The 3G/4G module enables the gateway to access the mobile communication network, allowing users to access the physical signs data through the mobile terminal and send corresponding control commands. When the ward’s physical signs data is dangerously abnormal, the general node will immediately send the abnormal alarm data packet to the GSM gateway, and the GSM gateway can communicate to Medical staff, family members, and emergency centers called the police to fight for precious rescue time to save lives.

Specifically, the blood pressure detection unit includes a numerical collector, an air pump, a control chip, a power supply and a general sensor node, the numerical collector and the air pump are connected to the control chip, the control chip is connected to the general sensor node, and the general sensor node is connected to the ZigBee gateway , the power supply one is used to supply power to the control chip, air pump and numerical value collector. The blood pressure sensor is an arm-type measurement method, which is tied to the upper arm of the arm through a cuff, and then inflated to 180mmhg, then the throttle valve is opened, and the high pressure and low pressure are found by leaking air at a rate of 2mmhg each time.

The chip has a flexible input multiplexer per channel that can be independently connected to internally generated signals for test, temperature, and persistent wire detection. In addition, various configurations of input channels can be selected to generate the right leg driver (RLD) output signal. The ADS1298 operates at data rates up to 32KSPS, allowing software PACE detection. Continuous wire-break detection is implemented internally to the device through pull-up/pull-down resistors or magnetizing current sources/drains. Three integrated amplifiers generate the Wilson central terminal (WCT) and Goldberger central terminal (GCT) required for a standard 12-lead ECG.

As shown in Figure 3, in the intelligent medical system based on the Internet of Things, the ward needs to wear medical sensors to collect and sense the data of his physical signs, such as blood pressure, pulse, blood oxygen and other data. To this end, it is first necessary to design the general sensor node. The general sensor node includes a processor 1, a radio frequency module, and a power supply 2, and the power supply 2 supplies power to the processor 1 and the radio frequency module respectively. In order to be portable and convenient for the guardian to use comfortably for a long time, the general sensor node needs to be improved and optimized in terms of volume, energy consumption, shape, etc., so that the guardian can wear and use it easily. Therefore, in order to make the general sensor node universal and realize the characteristics of modularization and assembly, the processor 1, radio frequency module and power supply 2 are combined into a general sensor node, which can connect various types of medical sensors through a general interface node. In the post-maintenance process, if it is necessary to increase the type of sensing data or the sensor module fails, only the sensor module needs to be replaced, so that the universal sensor node has better scalability and maintainability.
