A balanced stable system for elevator

The utility model discloses a balanced stable system for elevator, balanced stable system includes that signal stable system, rotational speed are with the speed matching system, and through the reasonable connected mode between pressure sensor, transport mechanism and the PLC controller of elevator, make signal transmission stable, avoid the distortion, lose etc. Simultaneously, satisfy certain relation between the acceleration of pressure sensor's output valve, servo motor's rotational speed, elevator, make the elevator the in -process of operation steady, comfortable, avoid the pause and transition in rhythm or melody to reduce the wearing and tearing of elevator operation in -process between to spare part, improve the life of elevator. 本实用新型公开了种用于电梯的平衡稳定系统，所述平衡稳定系统包括信号稳定系统、转速/加速度匹配系统；并通过电梯的压力传感器、传送机构与PLC控制器之间的合理的连接方式，使信号传输稳定，避免失真、丢失等；同时，压力传感器的输出值、伺服电机的转速、电梯的加速度之间满足定的关系，使电梯在运行的过程中平稳、舒适、避免顿挫，并减少电梯运行过程中对零部件之间的磨损，提高电梯的使用寿命。
