The Realization Of A Pile Integrety Tester Based On The Embedded Technology

The design methods and realization about pile integrity testing system based on the characteristic of the embedded technology are discussed in this paper. The hardware and software projects of the system are specially studied.The main work and achievements are summarized as follows.The performance characteristic of the pile integrity tester and the realization methods of high precision data collection system are studied deeply with the basic characteristic of the system, through the analysis to the back stress wave theory that is used to testing the pile integrity. According to the requirement of technical demands and function realizing, a holistic project about data collection and analysis based on the platform of S3CEB2410 is provided.The testing system is made up of the collection unit and the processing unit. Based on the key technologies such as dynamic magnify technology, advance trigger technology, two stage pipeline technology, data collection unit is realized. On the demand of the processing requirement, loose-coupling processing unit is designed. In the end, each function module of the testing system is debugged. From the result, the design of each function module is satisfied with the technical demands.Software design, debug methods and software developing flow are discussed in this paper, which is dived into two parts. One is data collection software that is developed in the Quartus environment, the other one is data process software that is realized in the EMBEST IDE environment and based on the platform of S3CEB2410.Debugging and testing performance characteristic of the whole system is accomplished. From the results show that the pile testing system is a high performance processing system with steady capability, accuracy, and is satisfied with the demands of the pile integrity testing system.
