Abstract: With the continuous development of science and technology, mobile phones have changed the way of life of human beings and facilitated the life of human beings. With the improvement of people's living standards, the functions of mobile phones are becoming more and more complete, and the functions of traditional mobile phones are limited. With the development of mobile phones, mobile phones have been developed. The Android system developed by Google is in the development stage and gradually matures. At present, Android system can also be applied to other fields, and the more popular sensor system technology is being innovated. It can be applied in the hospital field. This paper analyzes the development and research based on Android with medical sensor system.
Android's medical sensor system combines communication technology with medicine and is widely used in research, medical and other activities, and can fully utilize medical resources. The rapid development of the communications industry has also contributed to the progress of other industries. This paper analyzes the prospects of the installation market and uses Android as a powerful platform to develop and research medical sensing systems to improve the quality of medical care and promote the development of medical care.
1 The meaning of the medical sensor system
The medical sensor system is a wireless sensor network composed of sensor nodes and monitoring base stations, and gradually builds a community or hospital monitoring network, or even a wider range of telemedicine monitoring systems. The medical sensing system can collect the physiological data of the human body through the node and process the data, and transmit the data to the base station by using the communication technology. The base station reprocesses the data and forwards it to the new heart of the monitoring, the monitoring center performs processing and analysis, and feeds back the patient. The information is transmitted using communication technology to enable data sharing with other monitoring centers.
2 Inadequacies of medical sensing systems in China
2.1 Node mobility management is difficult
With the continuous development of the medical industry, the scope of the monitoring system has expanded to the community and other cities, even to the whole country. Due to the expanded coverage, the scale of the network will inevitably expand. However, the monitoring node and the base station are not fixed, which also brings difficulties to the management of the network monitoring. Therefore, under the existing technical conditions, there are certain difficulties in managing network nodes, so it is necessary to design a reasonable management node and network scheme.
2.2 The compression method is unreasonable
In order to achieve the normal transmission of medical data, it is necessary to ensure the integrity of the data. Because the data collected by the node is very large, and its storage is relatively small, the data must be compressed to ensure data transmission. The compression method currently used in China is a compression algorithm, but it is not suitable for the transmission of sensor nodes. Once the data is destroyed, it is easy to cause misdiagnosis to the patient. Therefore, it is necessary to study a more reasonable method based on this method. The best effort is to ensure that there is no problem with the data compression and transmission process.
2.3 Data security is not guaranteed
During the transmission process, the data is continuously guaranteed to be complete and more secure. However, since the network node of the sensor is self-organized, the data is easily damaged and the patient's privacy should be protected. Encryption technology must be used to protect patient information, but the sensor power of traditional technology is insufficient, and the confidentiality of information is not enough. Therefore, a more suitable sensor node encryption scheme must be designed.
3 Android hardware and software construction
3.1 Android hardware
Android system is based on the Linux core open handheld device platform, the hardware compatibility is good, the code is all open source, Android allows each application to access the mobile device through the standard API, and the resource is processed, it is really open and complete. Great development prospects.
3.2 Android software
The Android software platform consists of three parts, including the Linux kernel layer, the middle layer and the application layer. The Java runtime environment acts as a language for virtual machine translation and operation, allowing program code to be ported on each system to implement mechanism security, memory and processes. Management. As a kind of open language, the Java runtime environment is adopted by all applications in the application layer. The necessary conditions for the JRE to run the Java program include the virtual machine and the core class library. The main development tool is Eclipse, java platform. The development environment of the plug-in building software can be utilized, and the third party can develop the application software according to the needs of the market. Communication between components is done through Intent. Applications such as maps, contacts, browsers, etc. can be implemented through Android.
