Description
Technical Field
The invention relates to the technical field of elevator fault alarming, in particular to an elevator abnormity alarming system and method.
Background
The phenomenon that the elevator rushes to the top of a hoistway continuously due to failure of effective stopping when the elevator ascends to an upper end station is referred to as top rushing of the elevator. The squatting bottom of the elevator refers to the phenomenon that the elevator cannot be effectively stopped and collides with a pit when moving downwards to a bottom end station. Leveling of the elevator means that the car sill and the landing sill are about to move on the same plane when the car approaches a stop. An elevator safety loop refers to a loop in which all electrical safety devices are connected in series.
The abnormal phenomena of top flushing, bottom squatting and uneven floor detection monitored by the existing elevator are all from the original factory circuit of an elevator manufacturer, when the top flushing and the bottom squatting are abnormal, the elevator manufacturer only reports a safety loop fault, the safety loop fault is a wide concept, and when one or more safety component switches meet the triggering condition required by the safety loop, the safety loop fault can directly cut off the power supply of an elevator driving host machine to cause the elevator stopping. However, if no owner or property personnel pass when the elevator stops, if elevator maintenance personnel patrol the abnormal elevator, the time may be very long, only the mechanical structure is impacted under the condition that the elevator is empty, and if the elevator has wounded and has too serious injury and can not automatically give an alarm, the damage can not be measured without the invention. Moreover, the time when the abnormality occurs and the accurate abnormality information cannot be clearly known, and the maintenance personnel cannot know which elevator has the fault in real time.

The condition that the elevator is not at the top-rushing position or at the bottom-squatting position is indicated by being smaller than the first threshold and larger than the second threshold, the elevator is proved to be in a normal running range, and since no feedback signal of the laser diffuse reflection photoelectric device is received when the elevator stops in the normal running range, the condition that the uneven floor of the elevator exceeds the limit range of up-and-down deviation is indicated, namely serious uneven floor abnormity is considered to occur.
The position of the top-rushing or bottom-rushing part of the invention can just receive two feedback signals. Because the length of the photoelectric switch retro-reflection sheet towards the top and the bottom of squatting is longer than the length of the electric switch retro-reflection sheet for detecting the flat bed, the purpose of setting the photoelectric switch retro-reflection sheet to be longer is to ensure that two feedback signals can be received when the top and the bottom of squatting are generated, and when the elevator generates the top or the bottom of squatting, the elevator mechanical structure of the original factory can also force the elevator to stop running.
The number of the third photoelectric switch retro-reflecting sheets is the same as the number of elevator stopping layers, and when each photoelectric switch retro-reflecting sheet is located on an elevator flat floor, the first laser diffuse reflection photoelectric device and the second laser diffuse reflection photoelectric device are located at corresponding positions. In practical application, the number of the photoelectric switch retro-reflection sheets is the same as the number of elevator stopping layers (for example, 25 photoelectric switch retro-reflection sheets are needed for 25 floors, namely 1 for each floor), the installation position of the photoelectric switch retro-reflection sheet on each floor is determined to ensure that when the installation floor is at an elevator flat floor, the first laser diffuse reflection photoelectric device and the second laser diffuse reflection photoelectric device are within the range of the photoelectric switch retro-reflection sheets, and therefore whether each elevator floor is at the elevator flat floor can be detected in practical operation.
