Method for accurately testing remained riding allowance of elevator

Abstract

The invention discloses a method used for accurately measuring the elevator riding margin, which belongs to the sensing and measuring technical field. The technical proposal includes that stiffening material with proper Yong`s modulus is arranged between an elevator car and an elevator traction rope, or between two elevator traction ropes; a resistor stain gage is adhered on the surface of the stiffening material; the resistor strain gage constructs a huygens bridge circuit. The elevator bearing causes the deformation of the stiffening material, so as to cause the resistance variation of the resistor strain gage; the variation in the huygens bright circuit is converted into the voltage variation; a microprocessor MCU is adopted to read, process and compute the voltage variation; thereby, the accurate measurement of the riding margin of the elevator is realized. The method used for accurately measuring the elevator riding margin is different from the traditional elevator overweight alarm mode and solves the informing problem of the elevator riding information for the passengers.

Description

technical field [0001] The invention relates to the technical field of sensing and measurement, in particular to a method for accurately measuring the passenger capacity of an elevator. Background technique [0002] The elevator, which has a history of more than a hundred years, is an important building equipment that has long been familiar to people. With the rapid development of elevator technology, the elevator has changed from the most primitive load elevator to the exquisite passenger elevator today. With the expansion of cities in today's era, high-rise buildings With the increasing number of people and the improvement of architectural design, the ubiquitous elevator is an indispensable tool in people's life. At the same time, people have higher and higher requirements for elevators. [0003] In our country, elevators with advanced control technology are becoming more and more popular in recent years, especially in many newly-built intelligent buildings, various high-...

AI Technical Summary

Problems solved by technology

[0006] At present, there is no specific method for how to solve the elevator ride margin

Moreover, the existing elevator overweight alarm mechanism does not fully consider the passenger's need to know the specific number of people, and the accurate detection method of the elevator can take the margin will improve the service quality of elevator products and greatly improve the overall efficiency of the elevator. Provide customers with a cheap, safe and comfortable elevator service
