CONTROLLING SYSTEM IN ELEVATOR

Elevator control system

The invention provides an elevator control system associated with maintaining operation of a high-lift elevator, capable of well exerting stopping action near the bottom layer and high-layer testing operation according to the elevator control system. In the maintaining operation of a high-lift elevator, the maintaining operation speed (low-speed operation speed) is reduced from current 30m every minute to 15m every minute when it drops toward the bottom layer and when the elevator carrier exceeds the bottom layer to reach a limit switch (4). According to a preferable exertion mode of the invention, a final limit switch (5) may be prevented from action caused by damped oscillation of the elevator carrier via ladder variable of a speed indication and the maintaining time may be shortened when the high-lift elevator is in maintenance.

... 一种电梯，使用树脂包覆缆绳(31～33)内部的金属线，由收发信器(15、16)进行非接触性的信号传送。缆绳固定部(7、8)将2根缆绳内的金属线相互间连接并构成电气性闭环路。即使缆绳内金属线接通电流，漏出电流也不会流向电机(4)等。结果是不会从外部受到影响或者对外部造成影响。又，不需要进行插入专用信号线等的改造。即使不依存于环路构成的方式也能使用。由此，可提供不需要尾线而可在电梯控制装置(5)与电梯厢上控制装置(14)之间进行信息通信的电梯。 ...

Safe operation system of elevator

The invention provides a safe elevator operation system which can guarantee safety and reasonably keep a elevator working on. The invention confirms the elevator lobby door or the elevator cage door to be in an open state in the conditions except in a condition where the elevator lobby door(24N-1,N,N+1) and the elevator cage door(14) are in an opposite state and the elevator cage(1) are in a stop state, allows the elevator cage(1) to work in a preset safety operation mode in a limiting condition of guaranteeing safety, according to the door opening state information, for example the opening information of a amplitude detector(17,27N-1,N,N0+1). Consequently, the invention can facilitate passengers in a possible range.

AC motor controller

Elevator

The invention provides an elevator apparatus, which can measure the speed or position of the mobile body with a simple structure. On a surface portion of a guide rail of the mobile body which is used for guiding the elevator carriage and balancing the weight, a first conductor portion and a second conductor portion with different electromagnetic properties are arranged alternatively along the length direction of the guide rail. The mobile body is provided with a vortex sensor opposite to the first conductor portion and the second portion. When the mobile body is up and down, the vortex sensoralternately measures the first conductor portion and the second conductor portion. And a signal processing device measures the position or speed of the mobile body based on the output signal of the vortex sensor.
