With the rapid development of embedded systems technology , new design ideas and platforms emerging , increasingly wide applications . Traditional engineering test equipment commonly used discrete components constitute , bulky , power consumption , and poor anti-jamming capability shortcomings . SOPC ( programmable on-chip system ) is based on the FPGA of the SOC ( on-chip system ) to solve the program , the CPU, memory , I / O , digital logic resources system design requires functional unit integrated in a chip , and the flexibility to re- configure 's . Therefore , compared with the traditional instrument design patterns , testing instruments of the advanced technology used in engineering design is a breakthrough, helps to reduce the number of components to reduce system power consumption , extend system functionality , save development costs , shorten development cycle. This topic combined with a wide range of applications engineering test Low Strain Pile Integrity Tester , the study of low strain reflected wave acquisition system based on SOPC design . Resources on this topic using Altera's 32-bit Nios Ⅱ embedded soft -core processors and Cyclone Ⅱ the FPGA chip , the design of embedded hardware platform , and hardware and software co-design , the system quickly build . Low Strain Pile integrity testing of the system structure and function , the system by SOPC core module , signal acquisition modules, power modules , and a variety of interfaces , and completed the design and commissioning work . Real-time and reliability requirements for the system , successfully μC/OS- Ⅱ operating system ported to the the SOPC system platform . The system has good stability , low cost, low power consumption, etc. , can be widely used in low strain integrity testing of pile foundation . Meanwhile , the use of the SOPC flexible reconfigurability , the system can be quickly reconstructed to meet the needs of the other engineering detection applications , the modular design for intelligent instruments , provides a development platform for virtualization . The topics of research on the design of the new engineering test equipment has a certain reference value .
