Problems solved by technology

As a result, it sometimes took a long time before non-resident maintenance personnel arrived on site
In addition, when multiple elevators are installed in non-adjacent locations or when elevators operate independently, rescue work cannot be performed by adjacent elevators.

[0029] Figure 1 to Figure 3 is a diagram showing an embodiment of the elevator according to the present invention, wherein, figure 1 is a schematic diagram of a so-called electronic safety elevator 100 , in which the interior of a hoistway 90 is shown. figure 2 yes figure 1 A block diagram of the control portion of the electronic safety elevator 100 is shown, image 3 yes figure 1 An example diagram of the control flow of the electronic safety elevator 100 is shown.

[0030] Such as figure 1 As shown, a governor rope 20 is connected to the car 10 of the elevator 100 . The speed governor 21 is installed near the floor surface of the hoistway 90 via the speed governor rope 20 . To the car 10 of the elevator 100 is also connected one end side of a main rope 50 for driving the elevator car 10 up and down. The other end of the main rope 50 is connected to the counterweight 40 after being wound around a plurality of sheaves. The middle portion of the main rope 50 is wound ...

[0056] Figure 4 to Figure 6 Another example of the elevator 100 which concerns on this invention is shown. Figure 4 and figure 1 Correspondingly, it is a schematic diagram of the hoistway 90 of the elevator 100, wherein the elevator 100 has a mechanical safety device, and the mechanical safety device has a limit switch in the prior art. Figure 5 yes Figure 4 The control block diagram of the elevator 100 shown, Figure 6 yes Figure 4 The control flow diagram of the elevator is shown. The difference between this embodiment and the above-mentioned first embodiment is that there is no electronic security controller in this embodiment.

[0057] In the elevator in the prior art, the elevator control device 60 is not provided with an electronic safety controller, but only the elevator controller 61 is provided. In addition, in order to detect the position of the elevator car 10, a detected board 75 is installed on each floor. When the elevator car 10 is ascending and desc...

Abstract

The present invention provides an elevator that prevents passengers from being inside the elevator car for a long time. The elevator (100) comprises a first pulse generator (31) mounted on a driving motor (30), two second pulse generators (22a, 22b) mounted on a speed controller (21), and an elevator control device (60). The elevator control device comprises a distance count comparator unit (613) and an elevator stop command unit (613) that emits a stop instruction to the elevator in case of abnormal conditions. When the output error of the second pulse generators output by the distance count comparator unit is the predetermined value or less, a rescue operation (130) instruction is emitted. When an elevator usage normal operation processing (110) or an elevator stop command part allows the elevator to temporarily stop, the elevator car is moved to the nearest floor to allow passengers to get off.

Description

technical field [0001] The invention relates to an elevator, in particular to the rescue operation after the emergency stop of the elevator. Background technique [0002] Patent Document 1 discloses an example of a prior art elevator. In the elevator disclosed in this gazette, the output of the encoder installed on the governor for detecting the position of the elevator car and the height position of the elevator car installed in the vertical direction of each elevator car are used to detect the position of the elevator car. The optical sensor is compared to monitor the position of the elevator car. In the rescue operation, adjacent elevator cars are used to rescue passengers, and the height of each elevator car is directly detected by optical sensors, so as to more accurately and quickly align the heights of the two elevator cars. [0003] Patent Document 2 to Patent Document 4 disclose other examples of existing elevators. The above document discloses an elevator appara...
