起重机节能控制系统的设计

Design Energy-saving Control System of Crane

针对起重机在工作过程中的能耗问题,设计了一种起重机节能控制系统。本系统主要由主电路和控制电路组成,主电路以三相IPM模块为核心,控制电路是以单片机+SLE4520为核心的最小微机系统。控制电路产生6路SPWM控制信号,有序地控制主电路IPM模块中IGBT开关管的通断,将起重机重物下放过程中产生的再生电能无污染地送回电网再利用,不仅实现节能环保,还能有效降低起重机系统发热量,保证起重机的安全生产,提高系统的稳定性,减少故障率。

Design An energy-saving control system of crane in the paper in order to solve the problem of energy consumption. This system mainly consists of main circuit and control circuit, the three-phase IPM module is the core of the main circuit,control circuit based on MCU ＋ SLE4520 the minimum microcomputer system as the core,the control circuit produce six SPWM control signals, in order to Control the IGBT on-off switch tube of the IPM module,the renewable energy of weight down process can be sent back to the grid, the control system achieves energy conservation and environmental protection,and it can reduce System calorific value of crane,improve the stability of the system, reduce the failure rate.
