FPGA Based Processing Unit for a Checkweigher

Abstract

Abstract. This paper presents FPGA based module for a checkweigher utilizing Zynq type advanced signal processor. Developed module creates new possibility of implementation of advanced data processing algorithms for real-time signal filtering. Moreover, developed module makes possible data fusion from both position sensor, as well as driving coil of checkweigher. As a result the dynamic characteristic of weighting module can be effectively corrected, leading to significant improvement of functional characteristic of checkweigher. As a result the higher accuracy of measurements may be achieved.

Integrated SCADA Checkweigher System

“…With the array of unprocessed data loaded into the MATLAB database, signal processing stage starts. Figure 6 presents the signal processing algorithm implemented in the system [4]. Acquisition of the measurement is realized by parameterized step response function of the first order inertial object fitting:…”

“…Measurement errors are especially connected with vibrations, usually transmitted from the floor [3]. In order to remove the influence of this error source, good quality filters and signal processing algorithms have to be used [4].…”
