| The author educes Pseudo-random Multi-frequency acceptance real-time display system with the electrical prospecting apparatus's development trend. This real-time display system according to the relevant theory and hardware base is designed and implemented. When the real-time display system is designed, human-computer interaction? convenient operation and friendly interface will be consider enough. It will be the mouse action. Of course the keyboard does it. Each function will be done in one operation. The shortage is drastically spurned completing correspond function which needs multi-step complicated operation in keypad in the past. Because the waveforms of observation signal real-timely display, operator will find the observation mistake according to the signal's waveform and strength to assure the quality of electrical prospecting. The signal waveform can be adjusted in amplitude and time according to the operator's demands. This can zooms in and zooms out signal waveform to benefit operator's judgment. When the real-time display systems is come true, VC is used with Object Oriented analysis and design to fundamentally strike up the real-time display system's model and workouts the visual data acquisition monitoring program in Windows environments. Using the multithreading technology, collecting data?real-timely displaying signal waveform and data processing can be done at the same time. This overcomes the shortage of data waiting in DOS (Disk Operating System). The tests of real-time display system indicate feasibility and practicality of this research. |
