Problems solved by technology

[0009] However, according to the multi-level speed control scheme, although it is possible to ensure availability in terms of power consumption only when the no-load driving speed is higher than the load driving speed in consideration of the soft start of the motor through the inverter, since making the no-load The motor driven during driving stops, so that a large amount of starting power is consumed when restarting the motor, when the no-load driving time is shorter than the load driving time, due to the high restart rate and large power consumption, the actual availability is low, making this scheme Applicable only to job sites or equipment where air consumption is approximately 50% or less

Abstract

The present invention relates to a compressor operation control system and method for saving energy. The present invention analyzes operation record data recorded by monitoring the real-time operation status of a compressor, and actively drives the compressor with a PID pressure control method and an on / off control method depending on a change in air demand in a real environment, thereby reducing unnecessary operation of the compressor to thus be able to minimize power waste and maximize energy saving efficiency.

Description

technical field [0001] The present invention relates to a system and method for controlling the drive of a compressor for energy saving. More specifically, the present invention relates to a system and method for controlling the drive of a compressor for energy saving that enables a proportional-integral-derivative (hereinafter, referred to as "PID") control scheme and multi-level speed The (multi-step speed) control schemes are automatically switched between each other to drive the compressor according to the scheduling information, which is when the administrator provides the multi-stage speed (on / off) controllable interval (section) of the compressor And the monitor screen of the information about the real-time driving situation of the compressor and the corresponding interval selected to set the multi-stage speed (on / off) control scheme as the driving control scheme of the compressor and then set when driving the compressor, Among them, using the driving recording data ob...
