Reconstruction of Resistance Strain Sensor Experiment Platform Based on NI-WSN

In order to improve the level of experimental teaching of resistance strain sensor in higher vocational college, an experiment platform based on NI-WSN is reconstructed. First, the theory of wireless sensor networks is introduced. Second, the basic principle of resistance strain sensor is introduced. Then, the system structure is introduced. The resistance strain sensors and computer are connected with NI device. So the measured signal is sent to the computer, which can be analyzed and processed the data obtained from the above. It not only provides a convenience for students ´ experiment, but also makes implementation of network laboratory into possible. It improves the detection principle practical ability of students greatly, data analysis of experiment is more clear and accurate, save the education cost, and the teaching effect has been greatly improved. It is the reconstruction of the existing experiment equipment in our college. This is what is new in the paper.
