Research On DSP Test Machine Observation System

As China's comprehensive power is augmenting daily, each of the manufacturing industry to the standards set higher demands, the test machine's performance depends largely on the control unit and materials and workmanship, processing, etc, by comparison, the controllers are particularly important, the performance of digital, to higher and higher. in such a situation, the CPLD,DSP, and digital processor applications will be introduced.This article introduced based on the latest electronic technology and software design approach to design and implementation of the controller to take control of the computerized digital.The framework of the test instrument under control by the STC controller,The advantages of our electronics are:1. A/D-Conversion with high resolution (Standard:±240.000 steps)2. Data collection of all passages:it must be at the same time points for the measurement of data.3. Number gather frequency high frequency of several exciting500hz above4. Digital control:Large Know-How in the range of testing techniques5. Own power amplifieres for DC drives6. Additional parts like RMCs, aso.7. Simple communication between the producer software and the DOPE-Interface8. A fixed frequency filtering in 50hz - 100hz between the three levels low to filter.9. delivery with a "Corporate Design",On-time deliveries, modular design in hardware, to vote for the production enterprise production and ensure the timely supply services. Stc the new structure, high reliability is high level of integration and the good points and overcome traditional designs period, a large investment, flexibility, will gradually become the ideal design of complex numbers. first of all.Compared with traditional the stc controller has a high and low wastage anti-interference power, and use device in programming, to the new product, so that have wide application prospect.Paper introduces controls designed with related software tools. We implemented functional simulation of controller and proved that this new technique can achieve prospective purpose. And then, according to the design flow of controller, simulation, synthesize, routing and test were implemented in PCB. The result of the test on circuit board proved that STC controller can exactly achieve the transition of serial data to parallel data and have a good inverse proportion between performance and price.
