Research on curing monitoring system of a variable step adaptive algorithm of the CAN bus

Traditional monitoring system of curing machines can hardly meet controlling requirement not only because it is interfered easily by the hostile environment of locale in the respect of data acquisition, but also it has a low processing speed of data and weak communication ability. This study establishes a CAN bus monitoring network which can fully utilize the powerful digital signal processing ability of DSP, and adopts a new sort of variable step LMS adaptive filtering algorithm. The algorithm resolves better the contradiction between filtering speed and precision, and then improves the accuracy of data acquisition and the real-time data processing through controlling step-size factor. Furthermore, it optimizes the performance of the filter. The CAN bus network achieve effectively the real-time sharing and monitoring of data, besides, because of the open structure, the study also supplies a foresighted thought for the later construction and capacity expansion of the system.
