The Low-Layer Technology Development Of The Embedded Acoustic Detector System

The commonly used foundation becomes up to several dozen kinds of a method in the engineering construction of our country, it is to guarantee the quality important means of the project to detection and confirmation becoming a quality. This thesis gives an induction and summary of acoustic detector technology, and provides a method to apply embedded system in acoustic detector system.In the case of essential theories, some theory and method of acoustic detector have been deeply discussed, and then the technology of acoustic detector in the pile foundation engineering has been proposed.Including the main control system, super A/D acoustic sample system and automatic promotion system, acoustic detector has realized with several key technologies. The resolving of embedded system to the problem has analyzed.Design of the hardware is the most important in this pager. The minimize system of the main control system is introduced at first, then the basic principle of operation of CPU. The rich interface resources are the main reason that we choose the chip. The interface between the main control system and super A/D acoustic sample system, automatic promotion system is the key we discussed.As a difficulty of the acoustic detector, the high-speed digital system design is proposed. How to Implement Wiring rule of SDRAM, equal wire in the IDE bus and differential pair, impedance control in the network wiring is introduced specifically. The embedded operation system-WINCE is used in this system. In the case of the driver development in the WINCE, the process of the driver development and the technical difficulties on the super A/D acoustic sample system and automatic promotion system are elaboration.The performance index of the acoustic detector is the Anti-jamming. The empirical datum and improvement measure of noise have been discussed in this thesis.In the last part of the thesis, a conclusion about the whole dissertation has been given out and a possible object of researching and developing for us to continue has been put forward finally.
