2. Because the current building area utilization rate is high, the size of an elevator shaft reserved in a building is limited, a high-rise elevator is adopted at present, and assuming that an elevator with 25 floors and a load capacity of 1000Kg and 13 passengers are allowed, the maximum effective area of the elevator cage is 0.37m according to the current national standard2Then 13 people's elevator needs the maximum effective area of the car to be 2.4m2The corresponding well space of car area increase just needs synchronous increase and the required space of elevator door machine also can the grow, consequently, space will be as little as possible and the elevator can bear the weight of between as much as possible the conflict in the elevator well. In addition, part of elevator door structure is big burden, such as: large gate distance, super high door, super heavy door and the like need to be driven by a high-power door motor, but the size of the structural space of a standard elevator car is limited, so that the requirement of the size of the installation space of the high-power door motor cannot be met; under the condition, the structural design of the elevator car needs to be changed, and simultaneously, the design of increasing the elevator shaft space or properly reducing the effective passenger carrying area of the elevator car needs to be carried out, and at the moment, the corresponding performance configuration of the elevator can only be reduced.
3. At present, if a door machine system is put into use, if a component has a fault hidden trouble, the door machine system can still be used continuously and maintenance personnel can not know the situation as long as the door machine can be opened and closed, and the maintenance personnel can only maintain the door machine until the door machine fails and cannot work, at the moment, the maintenance period is long, and therefore the elevator can be used by passengers.

The second embodiment of the invention provides a novel intelligent complementary door motor double-driving method, which comprises the following steps: when the two intelligent drivers of the two door machines are in a normal state, the main control system of the SCAN elevator door machine controller sets the two intelligent drivers of the two door machines into a master mode and a slave mode through a CAN communication mode, wherein one intelligent driver of the door machine is used as a main control unit and works in a speed mode, and the other intelligent driver of the door machine is used as a slave control unit and works in a torque mode.
It should be noted that when a fault occurs, the master control system of the SCAN elevator door motor controller stops the master and slave control modes, quits the operation of the faulty group of working units, and adjusts the normal group of working units to a single machine operation mode.
The system provided by the first embodiment of the invention can realize the method. When two intelligent drive plates (intelligent drivers of a gantry crane) are in a normal state, a master control system of a controller of the SCAN elevator door motor sets the two intelligent drive plates into a master mode and a slave mode through a CAN communication mode, wherein one intelligent drive plate is used as master control and works in a speed mode, and the other intelligent drive plate is used as slave control and works in a torque mode; the intelligent elevator door control system comprises a master control intelligent drive board, a slave computer and a slave computer, wherein the master control intelligent drive board is used for controlling door opening and door closing signals of an elevator door and sending the signals to the master control intelligent drive board, the master control intelligent drive board is used for acquiring the position of the current elevator door through rotary encoding installed on a door motor, the slave control intelligent drive board is connected with the master control intelligent drive board through CAN data, and the master control intelligent drive board sends. At the moment, when the load of the door motor is heavy due to the structure of the elevator door, one door motor system with relatively small power and volume is used as a speed control mode, and the other door motor system is used as a torque compensation mode, so that the normal open and closed door operation conditions of the elevator can be completely met in the complementary control mode. Meanwhile, the master and slave control intelligent drive plates detect self faults or matched motor faults and rotary editing faults, namely fault information is sent to the master control system of the SCAN elevator door motor controller through CAN communication, and the master control system of the SCAN elevator door motor controller stops using the master control system. Once a fault occurs, the master control system of the SCAN elevator door motor controller stops master and slave control modes and switches and adjusts the control modes, a group of door motor intelligent drive plates and devices with the fault quit operation, a group of door motor intelligent drive plates which normally work are adjusted into a single machine operation mode, one door motor intelligent drive plate controls a door motor matched with the door motor, and rotary encoding position data installed on the motor are obtained. At the moment, one of the door machines is damaged, and the elevator can also run in an emergency, so that the emergency use of the user is not influenced.
A third embodiment of the present invention provides a novel early warning type intelligent complementary dual-drive system for a door operator, and the difference between this embodiment and the first embodiment is that, referring to fig. 3, the
When the two intelligent drive plates are communicated with the main control system of the SCAN elevator door motor controller, the main control system of the SCAN elevator door motor controller not only distributes the working states of the two intelligent drive plates, but also records the running states of the two intelligent drive plates, and the early warning intelligent module 9 processes various states according to the conditions of the two intelligent drive plates and makes corresponding early warning prompts. The warning processing mode and the prompt are shown in the following table:
