The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to describe technical scheme of the present invention in detail.
Fig. 1 is the structured flowchart of elevator starter system in the present invention.
As shown in Figure 1, the control setup of elevator is main reception signal and the parts of signal transmission.Elevator control gear is connected with motor driver, door lock shunting device, door machine, main contactor and band-type brake contactless switch.In the time that elevator control gear possesses starting demand, as receive outside call instruction in the same way, gate signal is closed in Xiang Menji transmission, triggers door lock shunting device simultaneously.Short circuit door lock thus, main contactor starts adhesive after the contact signal of door lock shunting device being detected.Elevator control gear is exported run signal to motor driver, and elevator drive main frame is carried out to excitation.When after door-closing in-place, discharge door lock shunting device, elevator control gear drives band-type brake contactless switch, and band-type brake is opened, and elevator moves immediately.
Below describe the flow process of above-mentioned whole pre-starting in detail, referring to Fig. 3:
Step 100, elevator control gear receive outgoing call in the same way or instruction, and described elevator control gear closes gate signal to the output of door machine.This step is the necessary condition of door lock shunting device action.
