Abstract

A control system for a construction elevator is provided. Output AC of a main contactor is converted through a frequency converter to generate and output frequency variable power which drives the motor of the construction elevator to operate. Control of an electrical system of the construction elevator is realized without an independent PLC module or a special controller, and the problems of large size and high cost caused by the independent PLC module or the special controller can be solved. The control system of the construction elevator does not have to be wired with the independent PLC module or the special controller in the prior art, and problems of poor system reliability and installation debugging difficulties due to complex wirings can be solved. The control system of the construction elevator can be arranged only by adjusting the parameters of the frequency converter, and the subsequent maintenance of the control system of the construction elevator is realized. The problems of complex maintenance in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of construction elevators, in particular to a control system for construction elevators. Background technique [0002] In the prior art, the electrical control system for the construction hoist is made separately, generally including a PLC hardware module or a dedicated controller, and a frequency converter for motor driving the construction hoist. [0003] Such as figure 1 As shown, the PLC module or controller 101 receives signals collected by the electrical system of the construction elevator, outputs signals for controlling the peripheral electrical system 100 (that is, the electric control circuit part of the construction elevator), and outputs signals for controlling the forward rotation, reverse rotation, and running speed of the motor. The signal is sent to the frequency converter 102, and the frequency converter 102 also outputs feedback signals such as operation or failure to the PLC module or the...
