Study on the communication robustness of detecting equipment based on wavelet multi-resolution analysis

This paper studies the CAN bus communication model of complex intelligent detecting equipment under serious electromagnetic working condition, analyses the effects of the serious interference to the equipment and reasons of the errors in data transmission when working. This paper employs the wavelet multi-resolution analysis, due to the property of time-frequency localization and multi-scale analysis; the disturbed CAN communication signal can be decomposed, filtered and reconstructed. This results in Simulink show that the communication robustness in interfered detecting equipment is improved greatly after wavelet transform.
