Referring to fig. 2, an embodiment of the present invention provides an auxiliary control system for an elevator, which is configured in a conventional elevator, and the auxiliary control system for an elevator includes a traction structure 10, for example, the traction structure 10 is a steel wire rope, an auxiliary motor 20 is also configured on the elevator, for example, the auxiliary motor 20 can be configured on a counterweight or a car of the elevator, an energy storage device 30 is also configured on the elevator, the energy storage device is connected to the auxiliary motor 20, and the auxiliary motor 20 is also connected to an auxiliary control device 40. In a possible embodiment, an elevator main machine disposed in a machine room is connected to one end of a steel wire rope, the other end of the steel wire rope passes through an auxiliary motor 20 and is connected to a rope head assembly 50 disposed at the top of a hoistway, in an actual application process, the auxiliary motor 20 is used as a diverting pulley in a default state, no influence is exerted on a traction process of the steel wire rope, an elevator car moves up and down in the hoistway under the driving of the steel wire rope, in the operation process, an auxiliary control device 40 monitors an operation state of the elevator in real time, for example, the auxiliary control device 40 may be connected to an elevator control system, acquires elevator operation state information fed back by the elevator control system in real time, and determines whether the operation state corresponds to a preset state, at a certain moment, the auxiliary control device 40 determines that a current operation state of the elevator corresponds to the preset state, and accordingly generates a corresponding auxiliary control command immediately, and sends the auxiliary control command to the auxiliary motor 20 to control the auxiliary motor to perform a corresponding auxiliary operation, such as, but not limited to, auxiliary braking, auxiliary energy harvesting, etc.

In the embodiment of the invention, the traditional elevator is improved, and the additional auxiliary motor 20 is configured on the basis of the traditional elevator, so that the additional auxiliary functions such as auxiliary braking, auxiliary energy collection and the like can be improved for the elevator on the basis of not influencing the normal operation of the traditional elevator, thereby realizing safer elevator riding experience, effectively utilizing the redundant energy generated in the elevator operation process, reducing the energy consumption and energy utilization in the elevator operation process and improving the economic benefit of using the elevator.

In a possible embodiment, the auxiliary control device 40 monitors the operation state of the elevator in real time, and determines that the operation state of the elevator is a preset abnormal state at a certain time, for example, the elevator is still moving in a flat-bed state currently, so that the elevator control system determines that the elevator has abnormal movement, that is, determines that the elevator is in an abnormal elevator stopping state, at this time, the auxiliary control device 40 receives the above abnormal state monitoring information fed back by the elevator control system, determines that the operation state of the elevator is the preset abnormal state, thus determining that the operation state of the elevator meets the preset state, and immediately generates a corresponding auxiliary control command, for example, the auxiliary control command is an auxiliary braking command, and sends the auxiliary control command to the auxiliary motor 20. After receiving the auxiliary braking instruction, the auxiliary motor 20 short-circuits the three-phase power line of the auxiliary motor 20 to make the auxiliary motor 20 in a star-closed state, and in this state, the auxiliary motor 20 stops rotating, i.e., the movement of the steel wire rope is inhibited, thereby assisting the elevator to brake.
