| The study is a cooperative project with Southwest Oil and Gas Field Company. The stray current tester is used to collect stray current signal. It has some features such as low-Power,automation and flexible configure.To match users'requirements, the study use MSP430F1611 as key device. The system consists of five modules, which are core module, data acquisition module, data save module, power module and display and control module, realize the function of data acquisition, clock reading and writing, system configuration, keyboard control, SD card data saving. Modify and maintain the system is convenient by adopt C language programming. It is proved that the stray current tester has achieved remarkable result by experiments. The tester can satisfy the needs of users, increase the degree of automation and reduce the labor strength in industrial production. |
