1、（2）Components diagram:（3） MD3000 is a multi-CPU parallel work of the biological signal acquisition and processing system, the basic principal diagram is as follows:According to the acquisition system principal diagram, suggesting that we should consider the following when doing the experiments:（1）.

2、Whether the need to stimulate? （control one chip machine 1, set the stimulation mode and parameters）（2）. Whether the need for sensor? （according to the non-electrical signals or electrical signals to determine）（3）. Direct current （DC） or alternating current （AC） input? （select the lower bound freque

3、ncy by the software）（4）. The magnification? （control one chip machine 2, set the magnification）（5）. On the speed of analog signal sampling? （control one chip machine 2, set the sampling interval）（6）. Whether the data is digital filtering? （the greater interference with the digital filtering to obtai

4、n the better curve.）（7）. Which is selected mapping way, a recorder or oscilloscope? If the continuous oscilloscope use signal or synchronization toggle? （8）. What data and index by the real-time processing?（9）. Whether the sampled data reserved?（10）.whether the data for further processing?Applicatio

5、n MD3000 system need to make clear the meaning of the above problems and familiar with the set or modify the method.MD3000 biological signal acquisition and processing system（二）System application software introduceMD3000 biological signal acquisition and processing system application software easied

6、 to learn and use is the standard Windows 32-bit application program, because of the graphic operation interface consistent with other Microsoft application program style. MD3000 application software is easy to install and unload, no special requirements on the hardware and do not seizure the specia

7、l resources of the PC. The users do not have to adjust the microcomputer port, and other complex operations. Done out of the box, very fast and convenient.My company has developed dedicated 98/2000/XP device driver, This device driver can effectively and complete hardware acquisition data transmitte

8、d from the PC memory to the upper application program, which is development WINDOWS sampling application program the key. This is an important symbol of our products with other similar products, but also the MD3000 biological signal acquisition and processing system is fully embodies a high-tech pro

9、duct.Because of the standard and specification program development, It has brought great convenience to the users. Including all mouse clicks, easy and convenient, muti-window operation sampling and processing the data. Sampling window size is adjustable, X,Y-axis compressed extended freely. Support

10、s all printers, and network resource sharing. Especially MD3000 can seamless connection with other Windows application （ACCESS, Excel, Word） as resources, meanwhile, It can share data that data processing work from the complex, a large number of labor have been liberated. Long time records, while sa

11、mpling side save, no maximum file size and time limited. Support Chinese long file names can be any file named. On the other side, WINDOWS softwares advantages can be reflected in the MD3000.The hardware is work base and the software is the core to complete the task in the MD3000. MD3000 can pass th

12、rough software settings on the hardware by the different ways of working to organize the software process. So it can replace the recorder, oscilloscope andstimulator, etal. And other experiment equipment. According to the operating method, MD3000 is divided into three operating modes:Recorder:multi-

13、channel recorder take the paper tracings operating mode of the signal curve. Drawing way is moving from right to left in full-screen. Signal of the slow, continuous record of the experiment. Such as blood pressure, respiration and ECG etal.Oscilloscope:the working mode of the multi-line memory oscil

14、loscope. the drawing method is left to right, adopt a painted one. For faster signals, especially the experiments of the periodic signal. Such as neutral stem action potentials.Slow-wave scanning:multi-line slow scan mode of operation of the memory oscilloscope. The drawing is from left to right, wh

15、ile wiping edge painting. Continuous record on the faster signal recorder way to full-screen mobile caused vertigo can be avoided in this way, difficult to observe the shortcomings of the curve. Adopt for continuous recording at a faster signal occasions. Such as depressor nerve discharge.Above all

16、three ways in the users can choose one. In addition to the curve drawing is a bit different, and other software to use is the same. This all the consistency of the operating mode to use, but also one of the big advantage of MD3000 system.三 MD3000 system software operating instructionAccording to the

17、 function complete division, MD3000 mainly complete the following three aspects of the operation: File operation, editing of the data, showing the style of regulation.Data measurement, processing, and Results of the chart output.Real-time to adjust the various parameters of the MD3000s hardware, so

18、as to make the hardware can be in the best condition of the work.When used, we should be clear that the function of the menu or button from the three aspects operation. Such we may shoot the arrow at the target at ourselves will.However, MD3000 system is a mult-windows software. In addition to some

19、setting windows, mainly working windows have three as follows. “sampling window”：showing sampling waveform. observation, measurement, select the waveform to be processed. “print edit window”：editing of printed curve which can adjust size and pattern and can be freely add, delete, modify the characte

20、r string. “data window”：similar to table window of the Excel,，measurement results shown on the curve.In the software menu functions described below is quite different for different window. In accordance with the currently active window, the basic principle make to invoke the appropriate processing m

21、ethods and functions.（一）MD3000 interface overviewInterface includes:title bar, menu bar, toolbar, state prompt bar and sampling window, deal window, data window, etal.and other appropriate child window composition. MD3000 start the interface as below follow:MD3000 system software1Title block: prompt

22、 experiment name, save the file path, filename and include as “zoom out”, “expand”, “close” button.2Menu block: according to different operating function, classification selecting operation. Include main menu name as follows:A.File: including all file operations. Such as open, save, print, exit, etc

23、.B.Edit: including all editing functions for the signal graphics. Such as cut, copy, paste, etc.C.View: whether or not to switch showing on the main visible part of the interface.D.Set: choose the system to run on the set.E.Experiment: select the specific teaching and scientific research and experim

24、ental projects have been completed custom experimental configuration.F.Deal: including all after sampling processing capabilities for signal graphics. Such as FFT calculate, digital filtering.G.Window: providing about window operation.H.Help: including online help, copyright information and Website

25、Links.3Shortcut toolbar: the commonly used tool buttons, as long as the mouse arrow is pointing to the button, click the left buttonin mouse, you can enter the operating.4Mark bar: add and edit of experiment tags, and positioning of the experimental data.5Channel sampling window: including three par

26、ts: Firstly, “channel control area” is displaying channel number and real-time control amplifier hardware, which is on the left-most of sampling window. Secondly, “waveform display area” is in central of sampling window. Which display dynamic signal waveform when sampling and display static waveform

27、 curve when processing. Whats important, further analysis and processing of artificial selected part of waveform. MD30006.0 is advanced multi-window to share data method, meanwhile, multi-window dynamic, static observation or measurement. Lastly, “result display control area” is on the right-most of sampling window. Which is showing
