Embodiment Construction
[0019] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.
[0020] refer to figure 1 As shown, the elevator system of the present invention includes a first logic unit 1, a plurality of terminal deceleration switches 2 and a first detection unit 3, wherein the plurality of terminal deceleration switches 2 can be realized by using an existing structure, and its The installation height in the hoistway can also be determined by the designer according to the conventional design in the field, and the first detection unit 3 can be realized directly by using an existing encoder. Similar to the prior art, the first logic unit 1 can also control the start, run and stop of the elevator, and can also use the first detection unit 3 to detect the position and speed of the elevator, so as to further monitor the running state of the elevator. control.

The invention discloses an elevator system, which comprises a first logic unit, a plurality of terminal deceleration switches, a first detection unit, a second logic unit and a second detection unit, wherein the first logic unit is used for detecting the position and speed of an elevator by using the first detection unit; the second logic unit is used for detecting the position and speed of the elevator by using the second detection unit; the first logic unit and the second logic unit are used for detecting the position and speed of the elevator independently, and can be used for independently controlling the elevator to decelerate or stop emergently; and the first logic unit and the second logic unit are used for monitoring whether the working state of the other party is normal. By applying the first logic unit and the second logic unit for redundancy safety protection, extremely high safety protection performance can be achieved.
Description
technical field [0001] The present invention relates to an elevator system. Background technique [0002] In the current elevator system, a main control board is generally used as the central control module of the whole system. In addition to the main control board, there are usually a plurality of terminal deceleration switches, an encoder and the like. The main control board can control the start, run and stop of the elevator, and can also use the encoder to detect the position and speed of the elevator, so as to further control the running state of the elevator. [0003] In order to ensure the safety of elevator passengers, the industry has extremely high design requirements for the safety protection performance of elevator systems. However, the current elevator system is difficult to provide high security protection capability, because it only adopts a single main control board as the central control module of the whole system. It may directly cause danger to the occup...
