Abstract
The utility model discloses a self -correcting gate unit, including speed given, speed given, speed controller, electric current amplitude limiting, current controller, current drive device, current detection device and door driving motor be electric connection in proper order, equal and the logic controller electric connection of current detection device and voltage detection device, logic controller and failure diagnosis electric connection, and failure diagnosis and failure logging electric connection. This self -correcting gate unit has still increased outward through classical velocity feedback and current feedback and has opened the door and the correction of the time of closing the door, according to speed given procedure revise of time to opening the door and closing the door of actual measurement, mainly revises accelerated speed and the speed at the uniform velocity the time, avoids leading to the fact the influence to the clamp force of closing the door, has increased the time correction that opens the door and close the door in the gate unit.
Description
Technical field
This utility model relates to city rail traffic technical field, is specially a kind of self-correcting door control unit.
Background technology
In track traffic, door device is a very important part, direct relation the safety of passenger, also it is one of vehicle arrangement of employing up in metro operation, and door control unit is the brain of door device, it is responsible for receiving command signal and realizes the on-off control of car door, and the relevant current door control unit of safeguard function is all adopt classical velocity feedback and current feedback, do not recognize out, the lockup importance to door device, current door control unit carries out real-time correction all without clamshell doors and the time closed the door, simply when door control unit powers on, switch gate is once at a slow speed, obtain the resistance etc. of this information such as each position, and as controlling this foundation the same day, when in operation, this makes resistance increase due to extruding or other reason of passenger, lockup will extend, lag behind other door in same compartment, at closing time owing to other door shuts, cause that car door returns or rests on this position, it is further continued for closing the door every the 5-10 second, owing to the air pressure in compartment in this process continues to rise, make to close the door and more and more difficult even cannot shut.
Utility model content
The purpose of this utility model is in that to provide a kind of self-correcting door control unit, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of self-correcting door control unit, including speed preset, described speed preset, speed control, current limit, current controller, current driving device, current sensing means and door drive motor are electrically connected successively, described current sensing means, voltage check device, door displacement calculating and speed preset are electrically connected successively, described current sensing means and voltage check device are all electrically connected with logic controller, described logic controller is electrically connected with breakdown judge, and breakdown judge and failure logging are electrically connected.
Preferably, described failure logging is electrically connected with data backup device.
Preferably, speed control is divergence type speed control or without section speed control.
Compared with prior art, the beneficial effects of the utility model are: this self-correcting door control unit, by also add the correction opened the door with lockup outside classical velocity feedback and current feedback, time clamshell doors and the speed preset program closed the door according to actual measurement are modified, main revise the speed accelerated and at the uniform velocity time speed, curve when slowing down generally is not revised, it is to avoid clamping force impacts to closing the door, be in door control unit, add the time adjustment opened the door and close the door.
