Description
Technical field
The present invention relates to railway transportation equipment field, especially relate to a kind of be widely used in the urban rail transit vehicles fields such as railway locomotive, motor-car, high ferro train, subway compatible shield door and the controlling device for doors of safety door, system and method thereof.
Background technology
There is subway construction project in many cities, the whole nation, and screen door is as auxiliary product, effectively can improve waiting environment, improves the safety of subway circulation, also can reduce the operation cost of subway simultaneously.Because different subway lines, different subway station (outdoor platform and subterranean stations), may select different door systems.Outdoor platform selects safety door system usually, and subterranean stations then selects screen door usually.In screen door a unit two fan Men Youyi driven by motor, and in safety door system a unit two fan doors respectively by two driven by motor.Door lock, for ensureing that two fan doors in cell gate close locking, is avoided arbitrarily being opened.Two fan door end limits in cell gate are embedded with trapezoidal rubber strip, because the inertia of door body can make trapezoidal rubber strip deformation after two fan door door-closing in-places, afterwards because the effect of reverse elastic force makes two fan doors mutually flick, in order to ensure that intermediate gap meets the demands, motor has a smaller power and drags the mutual jam-packed of two fan doors, ensure that door lock falls smoothly, locking two fan door simultaneously.
At present, the door control unit DCU(DoorControlUnit in accelerator control system, the abbreviation of door control unit) be only applicable to control motor, and two motors in safety door system in cell gate need to control two DCU.When closing two fan doors in cell gate in the technical data of door system, intermediate door seam there are certain requirements, in order to ensure that intermediate door seam meets the demands, motor door close put in place after can again to a power, allow two fan doors extruding in cell gate, door lock also can be made to fall smoothly.And in safety door system, in tug unit door, two motors of two fan doors are controlled by two DCU, be difficult to accomplish that two motors act in agreement, namely mean that the step of two fan doors is difficult to consistent, when likely causing two fan doors to close, crack between a door and its frame can not meet requirement and door lock can not fall smoothly.Door head lock is as a part for accelerator control system, for security consideration, Dang Menguan puts in place, by door locking, shield door/safety door effectively can be avoided passenger may to be made accidentally to drop on rail by arbitrarily opening damage, and avoid the serious accident that therefore may cause.
Two motors in safety door system in each cell gate are controlled by two DCU, increase space requirement, and the uniformity difficulty of two motor steps also increases.Meanwhile, a cell gate needs two DCU to control, and corresponding control line, holding wire also increase to some extent, therefore installs the space also corresponding increase required for DCU.And two DCU control two motors in a cell gate respectively, related data is difficult to accomplish real time contrast, compensation, so be difficult to accomplish acting in agreement of the two fan doors that two motors act in agreement in i.e. cell gate.When this just may cause two fan doors to close, crack between a door and its frame can not meet requirement or the door lock situation that can not fall smoothly occurs, namely wherein the more another Yishanmen of Yishanmen puts in place in advance, in order to ensure that middle crack between a door and its frame and lockup meet the demands, motor can give a power again after door-closing in-place, to allow extruding, this will produce the door early put in place and run boundary, and the door that evening arrives is to not position, thus door lock can not be fallen.
