Abstract: At present, the main treatment for diabetes is to measure the blood sugar level in patients with blood glucose meter, and adjust the blood sugar metabolism of patients. Based on the technologies and ideas related to wireless sensor networks and body area networks, a wireless remote blood glucose monitoring network system for monitoring the blood glucose of individuals and small areas is designed by using CDMA cellular mobile communication technology and 2.4G radio frequency communication technology. This blood glucose monitoring network can realize the remote diagnosis and treatment of diabetes, close the distance between doctors and patients, and alleviate the suffering of patients. The network architecture of the blood glucose monitoring network is introduced, and the design and implementation of the network node CDMA and 2.4G wireless communication functions are described in detail. Diabetes is a lifelong illness that is extremely harmful to the human body. The number of patients worldwide is increasing year by year, placing a heavy burden on individuals, families and society. In 2013, 5.1 million people worldwide died of diabetes, and one person died of diabetes every 6 seconds. Diabetes has become a worldwide problem. At present, diabetes is mainly controlled by measuring the blood glucose level of a patient with a blood glucose meter, and thereby regulating the glucose metabolism in the body. Various organizations and institutions recommend using a portable blood glucose meter to perform frequent self-glycemic tests. In recent years, wireless sensor networks and wireless body area networks developed on the basis of them have received extensive attention and become hot research fields. The wireless sensor network is a self-organizing wireless communication network system composed of a large number of micro sensor nodes deployed in the monitoring area for sensing, collecting and processing the sensing object information and transmitting the information to the observer, and can be widely applied to health care and military. , environmental testing, smart home, industry and agriculture and many other fields, and continue to expand into other areas. The body area network is a wireless network consisting of sensors installed around the human body or implanted in the human body to detect physiological parameters of the human body. It has broad application prospects in many fields such as health care, military, consumer electronics, and sports. This paper combines the related technologies and ideas of wireless sensor networks and body area networks to design a network system for remote wireless monitoring of human blood glucose in homes, communities, medical institutions, etc., enabling doctors to give real-time measurements based on measurement results at remote locations. The diagnosis and treatment opinions have brought the doctor-patient distance closer, and the use of medical resources with uneven distribution has been properly balanced, providing an economical and convenient solution for the strict control of diabetes. 1 CDMA and 2.4G communication technology From the perspectives of transmission rate, security, communication quality, power consumption, cost, etc., the blood glucose monitoring network designed in this paper adopts two kinds of wireless communication technologies: CDMA cellular mobile communication and 2.4GHz frequency band radio communication. CDMA cellular mobile communication technology is a 2G digital cellular system standard based on CDMA (Code Division Multiple Access) spread spectrum technology proposed by Qualcomm. Compared with other second-generation (2G) cellular mobile communication technologies, CDMA has strong anti-noise, anti-interference ability, good service quality, large system capacity, high sensitivity, low power consumption, low radiation, strong security, low cost, etc. Advantage. 2.4G RF communication refers to electromagnetic wave wireless communication technology operating in the 2.4GHz-2.5GHz ISM band. The ISM band is a freely open frequency band reserved for RF energy for industrial, scientific and medical purposes internationally. Devices operating in the ISM band do not need to be authorized, and can be used free of charge as long as they comply with the radio usage rules of the country. The ISM was originally proposed to adapt to the microwave heating technology that was emerging at the time. At present, some popular wireless communication technologies are built on the 2.4G free frequency band. Although this is contrary to the original intention of ISM, the development of 2.4G wireless communication technology. It does not interfere with various ISM devices, but promotes the vigorous development of 2.4G wireless technology. 2 blood glucose monitoring network The users of this blood glucose monitoring network can be divided into two types: individual users and collective users. Individual users are mainly diabetics and individuals who wish to prevent diabetes. For them, the blood glucose monitoring network can help them to self-check blood glucose anytime and anywhere, and transmit the test results to the monitoring network back-end service system, which is convenient for medical staff, family members and detectors to check the blood sugar level of the measurer. Collective users mainly refer to communities, hospitals, clinics, etc. that provide health care services. This blood glucose monitoring network can shorten the time of blood glucose testing for these users and improve the efficiency of staff. At the same time, the characteristics of less manual intervention can also reduce the staff's Operation error. According to the characteristics of the two CDMA and 2.4G wireless communication technologies introduced above, 2.4G RF communication is a low-cost, short-distance, low-power wireless communication technology that can be used for intra-area networking. Multiple nodes distributed within a certain range form a self-organizing network. Therefore, 2.4G technology is in line with communities, hospitals, In a scenario where there are multiple users with blood glucose detection requirements within a certain range, the blood glucose information measured by multiple nodes is aggregated to the local server through the formed network, so that the medical staff, the measurer and their families can grasp the measurer in time. The blood sugar situation, in order to strictly and carefully treat diabetes. However, in the case where there is no local server among the individual users and the collective users, since the 2.4G communication technology does not have the ability to connect to the Internet and cannot communicate with the remote medical server, the design selects a relatively high cost, but can achieve high efficiency. The CDMA technology for reliable Internet data transmission enables remote communication, so that the blood glucose data gathered after the 2.4G network can be sent to the remote server through CDMA. Considering cost, function and performance, this design divides the network nodes of the blood glucose monitoring network into two types: Full Function Device (FFD) and Reduced Function Device (RFD). The difference is that they can support The wireless communication function is different. FFD has both CDMA cellular communication and 2.4 GHz radio frequency communication; RFD does not provide CMDA cellular communication for cost reasons. It can be seen that the RFD node does not have the Internet connection capability and cannot directly upload measurement results to the background. If you want to transmit data to the background, you must use its 2.4GHz RF communication function to connect to other devices that can access the Internet to transfer data. Otherwise, , RFD can only be used as a local blood glucose measurement tool. The FFD node has no communication function restrictions, and can be networked by itself or transmitted by means of transit. 2.1 Personal User Network Architecture The monitoring network architecture for individual users is shown in Figure 1. The system is divided into four levels. The first layer is the individual user holding the FFD network node, and the second layer is the network environment on which the monitoring network depends, providing the basic network. Service, the third layer is the remote medical server background, which can be used to receive, store, process and query user blood glucose data. The fourth layer is the measurer's personal, medical staff or family members. In this scenario, the typical workflow of the blood glucose monitoring network is for individual users to use FFD devices for blood glucose self-detection; then use FFD's CDMA cellular communication CDMA2000 1X network transmission function to connect to the Internet, and the CDMA network service provided by the second layer will be measured. The blood sugar information is uploaded to the server on the third layer, and the third layer receives the data and stores it. Finally, the fourth layer user accesses the service provided by the third layer remote medical server through the network through the device capable of connecting to the Internet. Query user blood glucose data. When an emergency occurs when the blood glucose measurement result is too high or the measurer has acute physical discomfort, the user can also send an emergency distress signal to the medical staff and the family by SMS via the CDMA short message service (SMS) of the FFD device. .
