Multi-granularity SMT production line energy consumption modeling method

Abstract

The invention provides a multi-granularity SMT (surface mount technology) production line energy consumption modeling method, which comprises the following steps of: constructing a ternary matrix group (attribute matrix, abbreviated as [a] matrix); a power matrix, called a [p] matrix for short; the timer matrix is called as a [t] matrix for short. And the modeling and calculation of real-time energy consumption, state energy consumption and total operation energy consumption of SMT equipment energy consumption, process energy consumption, production line energy consumption, order energy consumption and workshop or enterprise energy consumption are realized by utilizing real-time attributes, power and accumulative timing. Wherein the ternary matrix group is easy to obtain, [a] a matrix is an equipment state matrix and can be obtained by reading a corresponding address of an equipment PLC (Programmable Logic Controller); the [p] matrix is an equipment starting, dormancy and operation power matrix and is a static data matrix; and the [t] matrix accumulative timing matrix can be realized at the equipment end through the operation of multiplying and accumulating (+ =) the unit time t and the [a] matrix. According to the method, the calculation process can be subjected to lightweight processing in a database, energy consumption modeling and calculation can be achieved without replacing hardware equipment such as an intelligent electric meter, a basis is provided for research in the core technical fields such as an SMT production line precise online energy efficiency optimization technology and a high-fidelity physical space-twin space mapping technology, and the method is suitable for popularization and application. And finally, the realization of energy consumption measurement, prediction, control and twinborn evolution of the SMT production line is facilitated.
