The second part is a detector which is used to detect the distribution of voltage on the patient ' s brain surface from all different directions. the third is a mixed signal processor ( c8051f020 ) which is used to control the other parts of the system and display some necessary information and convert the voltage signals into digital signals, as well as transmit the acquired data to the computer. the fourth is computer with eit software which is used to analyze and process the received data and construct a picture for the brain edema and haematoma on screen
32通道電阻抗斷層成像系統由4個部分組成：第一部分是正弦波恆流源，用來產生注入大腦的激勵電流；第二部分是電位信號的提取與轉換，用來提取當激勵電流注入時，在大腦表面形成的電位分佈信號；第三部分是數據採集與控制系統，用來控制激勵電流的頻率，注入方向，注入強度，控制採集大腦表面的電位分佈信號，並且將這些採集的電位分佈數據傳到pc機；第四部分是計算機eit成像軟體，用來接收下位機的電位分佈數據，並且對這些數據進行分析計算，重建電阻抗圖像。 -
The digital upward frequency conversion is the key element of the waveform synthesis. at the same time, basic theoretical analysis and optimum design are done for pci bus slave interface, fifo, transmit signal processor, digital - to - analog converter and logic control
本文對波形合成技術的核心? ?數字上變頻進行了深入細致的研究和介紹，同時對波形合成器中的pci總線介面、先進先出緩沖器、發射信號處理、數模轉換及邏輯控制等部分進行了分析和優化設計，給出了最佳設計方案。 -
In hardware system design, we adopted the microcontroller of at89c51 as the main controller of inferior processor, it is used to connect the modem with the data acquisition module. mcs - 51 assemble language is used to program the software of the device to realize the data transmission between modem and inferior processor. when the electric power in the run is beyond the specified value, the inferior processor can dial the phone number of central computer automatically to send the alarm message through the communication line. using a single - chip microcomputer to control a modem to transmit remote datas are introduced in detail
隨后詳細地介紹了系統的總體設計思想和具體的實現過程。在硬體系統設計中，採用了at89c51單片機作為下位機主控制器，用於連接modem和數據採集模塊。通過使用mcs51匯編語言編寫程序，實現了下位機與modem之間的數據傳輸，同時實現了自動檢測負荷，進行撥號報警的功能，其中重點介紹了單片機控制modem進行遠程數據傳輸的方法。
