Study On Network Communication Module Based On Embedded TCP/IP And Bioelectric Signal's Network Transmission

For some psychological and physiological reasons,there is an essential difference between data measured in the hospital and data measured in a relaxed environment for quite a few patients. To ensure the accuracy of pathological diagnosis,it is quite essential to make the patients measured in a relaxed environment. Moreover,it is inconvenient for the elder and the disabled to come and go between the hospital and the home.On this condition,we should make full use of telemedicine. Telemedicine is the focus of current research. The key point of telemedicine is telecommunications, the custom way of existing telemedicine system's telecommunication is by means of MODEM.This means can't serve the turn of the telemedicine's development and fall into disuse gradually for its slow speed. The network communication module studied in this article integrates embedded internet technology and wireless communication technology, it realized high speed real-time transmission of the patients'physiological data through internet at a low cost. Because the data is sending by internet which is an uniform and open system, it makes the module multifunctional, that is, it can be used at home for remote monitor and act as an ideal substitute of the existing remote monitor as well. The main works in this paper are listed as follows: ①Probe into the way of realizing embedded TCP/IP and it's specificities. ②Analyze the hardware scheme of the network communication module which based on embedded TCP/IP protocols. ③Research the basal theory of internet and TCP/IP protocols'structure and principles. ④Design the wireless-Ethernet receiving and sending module which based on embedded TCP/IP and compose the program in C language.. ⑤Analyze the theory of RTL8019AS network controller and the way how the MCU drive RTL8019AS to receive and send data. ⑥Compose the terminal software with Visual C++ which includes remotely connect and data's receiving, real-time displaying and analyzing. All these studies get elementary success and basically achieve the design purpose. Which establishes a good basis for the future development.
