Problems solved by technology

[0002] Most of the traditional elevator door control systems are composed of inverters, motors and bistable limit switches. This speed control system based on limit switches increases the system's dependence on the hardware structure. Damage to a certain limit switch will cause the door to The elevator system cannot operate normally, which affects the performance of the entire elevator system. The limit switch has a certain service life and needs to be replaced regularly, which causes a waste of manpower, material resources and financial resources.
In addition, there are still many imperfections in the software of the traditional elevator door machine speed control system. The same control system cannot be applied to elevator doors with different door widths. It has functions such as fault-free self-reset, power-on automatic door closing, and system fault tolerance. The degree of automation is low, which increases the frequency and difficulty of debugging by maintenance personnel, and reduces the flexibility and reliability of the system

Description

technical field [0001] The invention belongs to the field of automatic door control, in particular to an intelligent frequency conversion control device for elevator doors with limitless switches. Background technique [0002] Most of the traditional elevator door control systems are composed of inverters, motors and bistable limit switches. This speed control system based on limit switches increases the system's dependence on the hardware structure. Damage to a certain limit switch will cause the door to The elevator system cannot operate normally, thereby affecting the performance of the entire elevator system. The limit switch has a certain service life and needs to be replaced regularly, which causes a waste of manpower, material resources and financial resources. In addition, there are still many imperfections in the software of the traditional elevator door machine speed control system. The same control system cannot be applied to elevator doors with different door wid...
