Description

Technical Field

[0001] The utility model relates to the technical field of energy consumption management, in particular to a monitoring device for portable energy-consuming equipment. Background Art

[0002] Multi-energy monitoring and analysis devices are primarily used to rapidly monitor energy consumption (including media) and analyze energy anomalies in equipment that simultaneously uses multiple energy sources or media (such as electricity / argon, electricity / carbon dioxide, electricity / cutting fluid, and electricity / mixed fluid). These devices are often bulky and fixed in location, making them difficult to move. Therefore, existing methods for collecting energy data typically involve installing transformers on the equipment's distribution cabinet and flow meters on fixed pipelines. However, with current process adjustments, many energy-consuming devices are frequently relocated, which presents challenges for existing energy data collection devices. This is particularly true when a single device uses multiple energy sources simultaneously, such as gas shielded welding machines or mobile local heating equipment, and requires simultaneous collection of multiple signals, including electricity and gas. Data collection requires shutting off the power, installing energy meters and transformers on the distribution cabinet, and installing flow meters on the gas pipelines. This results in power and gas outages, disrupting normal production. Furthermore, this data collection method takes a long time to obtain. Utility Model Content
