Abstract
The invention relates to the technical field of elevators, in particular to a protection circuit and a protection method for an elevator door motor. The protection circuit for the elevator door motor comprises a main control panel, a car top plate and a door motor controller, wherein a unique ID code which cannot be changed is built in the door motor controller; the main control panel is connected with the car top plate through a communication interface; the car top plate is connected with the door motor controller through an RS485 interface in a terminal control mode; and the purposes of door opening/closing operation and authorization are achieved.
Description
Technical field
The present invention relates to elevator technology field, particularly relate to a kind of elevator door-motor protective circuit and guard method.
Background technology
The vertical conveyor of elevator to be a kind of with electrical motor be power, is equipped with box like gondola, takes advantage of people or carrying goods for tier building.Elevator, as the transport facility of vertical direction, has become important Architectural Equipment and indispensable at skyscraper and public place.Along with the development of computer technology, automatic technology and Power Electronic Technique, modem elevator has become typical electromechanical integrated product.Along with the raising of overall national economy strength, the personal consumption level of the people rises appreciably, real estate developer releases medium-to-high grade little high level and high-rise residential building one after another energetically, has driven increasing rapidly of residential lift, becomes the main growth factor in whole elevator market.
Traditional door machine controller, the mode of switch gate has the modes such as Terminal control, point operation control, Non-follow control and demo mode.General control systems output switch gate signal, utilize the Terminal control pattern of door machine controller, opposite house machine carries out switch gate operation, but does not have to carry out communication with the control system of elevator, cannot realize the operation of switch gate and the object of mandate.
Summary of the invention
The object of the invention is to provide a kind of elevator door-motor protective circuit and guard method for the deficiencies in the prior art, the operation of switch gate and the object of mandate can be realized.
For achieving the above object; the present invention adopts following technical scheme: a kind of elevator door-motor protective circuit; it comprises master control board, sedan-chair top board and door machine controller; door machine controller is built-in with a unique and ID code that can not change; described master control board is connected with sedan-chair top board by communication interface, and sedan-chair top board is connected with door machine controller with Terminal control pattern by RS485 interface.
Described communication interface CANBUS interface.
It also comprises inspection switch, and inspection switch communication connects described master control board.
A kind of elevator door-motor guard method, door machine controller built-in one unique and ID code can not be changed, after sedan-chair top board reads the ID code of door machine controller by RS485, and mate, after the match is successful, door machine controller just can normally work; Sedan-chair top board carries out communication by RS485 interface and door machine controller, and door machine controller sends a handshake frames every 500ms, after sedan-chair top board receives handshake frames, returns an acknowledge signal to door machine controller, then think sedan-chair top board and the communication of door machine controller normal; When elevator is in standby time, do not send handshake, when there being call instruction, sedan-chair top board and door machine controller carry out communication and shake hands; Under elevator is in normal condition, only shake hands successfully, the Terminal control pattern of door machine controller could use, and namely system is in significant condition; When elevator is in inspecting state or urgent motor-operated running state, after sedan-chair top board receives the communication signal of master control board, even if sedan-chair top board and door machine controller are not shaken hands successfully, Terminal control pattern is also effective, avoids occurring in installation process the situation of switch gate occurring.
Beneficial effect of the present invention is: a kind of elevator door-motor protective circuit of the present invention and guard method, all can realize the operation of switch gate and the object of mandate.
Accompanying drawing explanation
Fig. 1 is functional block diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further illustrated: as shown in Fig. 1; a kind of elevator door-motor protective circuit of the present invention; it comprises master control board 1, sedan-chair top board 2 and door machine controller 3; door machine controller 3 is built-in with a unique and ID code that can not change; described master control board 1 is connected with sedan-chair top board 2 by communication interface, and sedan-chair top board 2 is connected with door machine controller 3 with Terminal control pattern by RS485 interface.Described communication interface CANBUS interface.Further, it also comprises inspection switch 4, and inspection switch 4 communication connects described master control board 1, presses inspection switch 4 and makes elevator be in inspecting state.Control system is by RS485 and Terminal control pattern, and opposite house machine controller 3 carries out switch gate control simultaneously, thus reaches the operation of switch gate and the object of mandate.
A kind of elevator door-motor guard method of the present invention, door machine controller 3 built-in one unique and ID code can not be changed, after sedan-chair top board 2 reads the ID code of door machine controller 3 by RS485, and mate, after the match is successful, door machine controller 3 just can normally work; Sedan-chair top board 2 carries out communication by RS485 interface and door machine controller 3, door machine controller 3 sends a handshake frames every 500ms, after sedan-chair top board 2 receives handshake frames, return an acknowledge signal to door machine controller 3, then think sedan-chair top board 2 and door machine controller 3 communication normal; When elevator is in standby time, do not send handshake, when there being call instruction, sedan-chair top board 2 and door machine controller 3 carry out communication and shake hands; Under elevator is in normal condition, only shake hands successfully, the Terminal control pattern of door machine controller 3 could use, and namely system is in significant condition; When elevator is in inspecting state or urgent motor-operated running state, after sedan-chair top board 2 receives the communication signal of master control board 1, even if sedan-chair top board 2 and door machine controller 3 are not shaken hands successfully, Terminal control pattern is also effective, avoids occurring in installation process the situation of switch gate occurring.Control system is by RS485 and Terminal control pattern, and opposite house machine controller 3 carries out switch gate control simultaneously, thus reaches the operation of switch gate and the object of mandate.
The above is only better embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in patent claim of the present invention change or modify, and are included in patent claim of the present invention.
