Design of mobile medical guidance system based on NFC
OFweek medical network information is difficult to register, long queues, numerous documents, no clinics, etc. The problem of medical treatment has become increasingly prominent. With the rapid development of NFC technology, namely, close-range wireless communication technology, and the popularity of Android mobile phones, mobile medical will become improved. A good way to seek medical treatment. Combine NFC technology with Android platform, use M/M/c queuing model to design optimal treatment route plan class to realize medical treatment without card, paperless, visual map help, etc. Mobile medical guidance platform. Since the launch of the new medical reform, the demand and development potential of China's medical and health industry informationization has been huge. Residents' demand for medical and health services and products is very low, and there are many problems in China's medical and health system. Among them, the problem of difficulty in seeing a doctor is most prominent, which is reflected in the difficulty of registration, long queue time, cumbersome payment process, large hospitals, and excessive loss of documents. Mobile medical care will become a good way to improve current medical treatment. the way. Mobile medical care is developing rapidly in foreign countries, and more and more medical and health App applications have entered people's lives. The data shows that the global mobile medical market is expected to increase from $4.5 billion to $23 billion in 2013-2017. Significant achievements include: "Smart Pipeline" developed by NTT DoCoMo in Japan; Mobile-Health account dedicated to users paying for mobile medical expenses by Qatar Telecom. The "good doctor" website in China has also launched the iphone client. Users can retrieve information about hospitals and doctors through their mobile phones. In Guangdong, customers can make an appointment at 12580, pay the registration fee with their mobile phone, and after receiving the QR code, they can go to the hospital self-service terminal to print the registration certificate to see the doctor. At the same time, mobile medical care has limitations in China: the lack of 3G network, the impact of Internet bandwidth restrictions, and the backwardness of equipment in primary hospitals have limited the development of mobile medical care to a certain extent. However, with the popularization of NFC mobile phones and the continuous development of information technology, many mobile phones can realize the good application of NFC tag function. The mobile phone can be different in driving mode, silent mode, bedroom mode, conference mode, WLAN display and application. Switch between scene modes freely. At the Phillips Arena in the United States, customers can use NFC phones to shop, download movies, and view posters in franchise stores. In Caen, Normandy, France, residents can use NFC mobile phones to pay at selected retail outlets and park equipment, download famous tourist attractions, movie trailers, and car schedules. Therefore, consider combining NFC technology with the Android platform to apply it to mobile healthcare. The main functions are as follows: appointment registration, payment of medical expenses, viewing map consultation room, viewing hospital doctor information, viewing personal medical records, checking the best treatment plan route, printing various documents and so on. 1 NFC technology 1.1 Basic concepts of NFC NFC (Near Field Communication) is a short-range wireless communication technology that evolved from contactless radio frequency identification (RFID). It combines an inductive card reader, inductive card and point-to-point function on a single chip. High-frequency radio technology for identification and data exchange with compatible devices over short distances. Operating at a frequency of 13.56 MHz within a distance of 10 cm allows for contactless point-to-point data transmission between electronic devices. NFC terminals mainly have three working modes, and the communication process is shown in Figure 1 [1]. (1) Active mode. The NFC terminal can act as a card reader and issue a radio frequency field to identify, read/write other NFC device information. (2) Passive mode. The NFC terminal is modeled as a card that passively responds to readings or writes information in the RF field emitted by other devices. (3) Two-way mode. Both sides of the NFC terminal actively send out the RF field to establish peer-to-peer communication, which is equivalent to the two NFC devices are in active mode. Figure 1 NFC communication process 1.2 Android and NFC 　　 Android is an open source smart operating system designed by Google and has a common application in the field of mobile devices. According to Ai Media's "2013 Q2 China's smartphone market operating system distribution status" data display (see Figure 2), Android share expanded to 74.5%, currently occupying the largest market share. Android not only provides a Java-based SDK, but the source code is open. Figure 2 2013 Q2 China smartphone market operating system distribution NFC provides a simple, non-touch solution that allows consumers to quickly exchange information and access their content and services [2]. The combination of mobile phones and NFC technology will bring great convenience to consumers' lives, such as mobile payment, identity, mobile medical and so on. At the same time, the openness of the Android system and its powerful communication capabilities make NFC's various applications easy to implement on Android. According to China's industry information statistics, as shown in Figure 2, global NFC mobile phone shipments in 2012 will be approximately 125 million, and will reach 285 million in 2013, with a growth rate of 128%. The number of NFC mobile phones will grow rapidly in the next two years. In 2015, the penetration rate of the NFC mobile phone market will reach 51%. Moreover, many mobile phones such as Samsung, Xiaomi, Blackberry and Sony now have NFC functions.

The main nutrients in beans include carbohydrates, protein and fat. Protein in beans is an important component of beans.
â‘ Protein: Soy protein in eight kinds of essential amino acids the human body needs with the United Nations food and agriculture organization (FAO) recommended are very reasonable compared to the ideal value of soy protein has good amino acid composition pattern, rich in glutamic acid, alanine and aspartate and contains high lysine, methionine and tryptophan (amino acid) sulfur content is low, However, some grains contain high content of sulfur amino acids and low content of lysine, so some grains can be appropriately combined with legumes, which can play a complementary role in protein, so as to improve the nutritional value of food .
â‘¡ Fat: soybean and black bean have higher fat content, while other beans, such as kidney bean, except soybean and black bean, have lower fat content, but their fatty acid composition pattern is better, mainly polyunsaturated fatty acid, mainly including linoleic acid, linolenic acid, etc.
â‘¢ Vitamins: beans contain vitamin A, vitamin B, vitamin C and vitamin E.
â‘£ Minerals: different beans contain different minerals, such as soybeans are rich in iron, kidney beans contain calcium, iron, potassium, magnesium.
⑤ Dietary fiber: beans contain dietary fiber, which is good for the body.
â‘¥ Pigment: soybean isoflavones are one of the flavonoids, mainly exist in leguminous plants, flavonoids is a kind of plant pigment. Soybean isoflavones are secondary metabolites formed during soybean growth. It can compensate for the lack of estrogen in women after age 30, improve skin moisture and elasticity, relieve menopausal symptoms and improve osteoporosis. The estrogen effect of soybean isoflavones affects hormone secretion, metabolic biological activity, protein synthesis and growth factor activity.
