Abstract

The invention discloses a workshop equipment energy online monitoring and control system. Each to-be-monitored machine in a workshop is equipped with a PLC for acquiring a starting signal of equipment, is equipped with an EMU4-HD electric energy module for acquiring real-time electric energy data of the machine, or is equipped with a pulse module A for acquiring cooling water consumption data of the machine, or is equipped with a pulse module B for collecting natural gas consumption data of the machine; then, a CC-Link communication module is adopted to be connected with each machine to serve as a communication slave station, and the CC-Link communication module is connected to a server; and then the supervisor computer is connected to the server to feed back and control the start and stop of each machine. According to the invention, energy signals of each machine, electric energy, cooling water, steam, natural gas and the like can be monitored respectively, and a feedback control mode with fewer control circuits can be adopted.

Description

technical field [0001] The invention relates to an energy-saving technology in the electromechanical industry. Background technique [0002] Modern industry has continuously improved the requirements for enterprise production management. It not only monitors and controls the status of the production site, but also requires the combination of on-site information and management information to establish a fully integrated, open, and comprehensively automated information platform to form a comprehensive management system. Comprehensive processing of information such as decision-making, management, planning, scheduling, process optimization, fault diagnosis, and on-site control. [0003] At present, China only collects and draws data on energy consumption of factory energy-consuming equipment, and there is no high-throughput analysis and calculation of these data. Even the designated server is only for a certain aspect of data collection function, requires specific host computer...
