Elevator control system with retina recognition function

Abstract

The invention relates to an elevator control system with a retina recognition function. The elevator control system comprises a car and a center control mechanism arranged in the car. The center control mechanism comprises a panel and a center control assembly. A displacement adjusting mechanism is in transmission connection with a camera and comprises a height adjusting assembly and a horizontal adjusting assembly. The height adjusting assembly comprises a first motor, a first drive shaft, a first gear and a lifting rod. The horizontal adjusting assembly comprises a transmission frame, a guide unit, a second motor, a second drive shaft and a second gear. A work power source module comprises a work power source circuit. In the elevator control system with the retina recognition function, precise control over the displacement of the camera is achieved through the displacement adjusting mechanism, thus a retina of a user can be precisely collected and recognized, and the practicability of the system is improved. In the work power source circuit, the model of an integrated circuit is M5230L, the integrated circuit is provided with two branches of direct voltages to be output, the applicable range of the work power source circuit is increased, and the practicability of the system is improved.

Description

technical field [0001] The invention relates to the field of elevator control systems, in particular to an elevator control system with the function of eye membrane recognition. Background technique [0002] The hardware of the elevator control system is composed of car control panel, hall door signal, PLC, frequency converter, and speed control system. The frequency converter only completes the speed control function, while the logic control part is completed by PLC. PLC is responsible for processing the logical relationship of various signals, so as to send start and stop signals to the inverter, and at the same time, the inverter also transmits its working status to PLC to form a two-way communication relationship. The system is also equipped with a rotary encoder and PG card coaxially connected with the motor to complete speed detection and feedback, forming a speed closed loop and a position closed loop. In addition, the system must also be equipped with a braking resi...

Problems solved by technology

[0003] In the existing elevator control systems, many of them have the user's identity recognition function, part of the recognition method is to use the eye mask recognition method. The height of the recognition mechanism is fixed, so that different users will affect their recognition experience due to the difference in height during the recognition process, reducing the practicability of the system; not only that, but in the process of running the current system, all It is necessary for the working power supply circuit to output a stable working voltage, all of which use conventional voltage-stabilizing transistors for voltage-stabilizing output, but due to the lack of output voltage circuits, the practicability of the system is reduced
