The invention can realize information sharing between various frequency conversion equipments, and has good scalability and high reliability.

Description

technical field [0001] The invention relates to the technical field of frequency conversion control systems for ships, in particular to a frequency conversion control system, method and electronic equipment. Background technique [0002] There are more and more applications of frequency conversion control systems on ships, and the control objects are becoming wider and wider. Conventional ones include cooling sea water pumps, low-temperature fresh water pumps, engine room fans, air-conditioning compressors, anchor winches, etc., to achieve as many energy-saving goals as possible . [0003] At present, the commonly used control method is single-machine single-control, but this control method has poor integration and almost no information interaction capability. It is difficult to fully synchronize when multi-machine cooperative control is required, and the comprehensive control effect is poor. In the input mode, variable signals are difficult to share, resulting in low utili...

AI Technical Summary

Problems solved by technology

This kind of frequency conversion control system often leads to inflexible control due to over-centralization, and the frequency conversion equipment between various central control cabinets cannot be controlled cooperatively, and the line difference can be expanded.
