Energy Consumption Detection Method of Printing Press Based on Hall Effect

The work aims to form a digital inspection system for the energy consumption of printing presses by the Hall element method. By establishing a framework system for the energy consumption index model of printing presses, a power consumption evaluation standard of printing presses was formed based on the total power consumption index, average value index, and power consumption ratio index, and the energy consumption evaluation criteria were improved. The Hall element with high sensitivity and good stability was used as the energy consumption detection element. The detection circuits of the Hall effect, magnetically balanced current and voltage Hall sensors were analyzed. The current and voltage of each load circuit were measured by voltammetry power measurement method and the detection data were digitized through the A/D conversion module. Then, the collected digital signals were calculated, output, and displayed through the hardware control core. The CAN bus was used to implement digital information exchange between the hardware control system and the upper computer. As a result, a digital energy consumption detection system platform for the printing press group was formed, which realized the data interaction between the peripheral equipment and the upper computer, and made the printing press group take data as the core. Through energy consumption detection, energy efficiency analysis, energy cost control, and energy index optimization, energy efficiency was improved. The realization of energy consumption detection can not only reduce the redundant power consumption, but also is conducive to monitoring the stability of the circuit. It is feasible to use the Hall element method to realize the energy consumption detection of the printing press group.
