Signal processing is an indispensable part of a precise detection system. Advanced signal processing technology is a primary factor to improve the accuracy of detecting system.

The system comprehensively applied advanced MCGS configuration software, GPRS module, signal detection and processing technology, can effectively monitor, do statistics and enquire all kinds of data.

In this paper, a signal processing system based on PCI bus is designed and completed, which is made up of four chips of ADSP21060 (SHARC) which the most advanced parallel DSP device.
