Design And Research On Smart Relay Measuring System Base On ARM

Relay plays an important role in various fields of national economy, especially in industry control board. For a relay, whether it can work well and truly is an important guide line to its reliability. The contacts act right or not can be decided by analyzing the contact voltage drop of relay, which is a key test item in most relay reliability examination equipment. With the development of science and technology, various examination methods take place. In this article, a new test smart system based on ARM is introduced.At the beginning of this paper, the working principle and application of electromagnetic relay is analyzed in depth. The main parameters of the relay are studied by test principle, as such pick-up / release voltage and time, shock resistance, coil resistance. A novel smart relay testing system based on ARM Cortex kernel is designed.On software platform, the system selected the 1AR software platform and LabVIEW program development environment, IAR integration platform C-SPY mode of J-LINK emulator can achieve a seamless link and support the ARM mode to compile. The LabVIEW program development environment is used to design the host computer PC control interface. The LabVIEW interface can control upper and lower limits values of test parameters, and display the results of test parameters.Finally, this proposed system is tested based on software and hardware design. The results show that actual test results and expected results are basically consistent, and the system has accurately test for relay parameters. The platform is a new viable solution for multi-parameter set of relays, and it can be significant cost savings with high economic value and market prospects.
