Abstract
The invention discloses a kind of detection cage guide depth of parallelism device, belong to cage guide flatness detection field.Device is made up of housing, gyroscope acceleration transducer, PSD position sensor, laser, operational amplifier, data acquisition module, PC；Its middle shell is fixed on single guide rail, laser is radiated at the PSD sensor outside being exposed to and realizes the measurement of the initial value to vertical angle, during full detection, gyroscope realizes the measurement of the perpendicularity to single guide rail, it is arranged on another root guide rail by another identical device, realize the measurement to the two amount, this 2 covering device measurement to data realize analog quantity by data acquisition module and pass to PC host computer respectively to the conversion of digital quantity and realize the contrast of 2 set waveforms, thus realize the measurement to 2 guide rail parallelisms.
Description
Technical field
The present invention relates to cage guide flatness detection field, especially Multi-Parameter Measuring System for Elevator Rails field.
Background technology
In elevator industry, typically can evaluate the quality of an elevator in terms of three: safety, comfortableness and functional.
The depth of parallelism problem of guide rail can be serious have influence on elevator run safety and comfort level.But traditional measuring method exists
Many disadvantages.Modern measuring method useful RSU sensor, the most useful laser measurement, but these methods however accumulate exactly
Error is big, otherwise due to laser range, the problem of focal length telemeasurement can not cause certainty of measurement the highest, not be suitable for high level
The measurement of cage guide.
Traditional method error of measuring is big, is limited to the level of survey crew, it is impossible to objective obtains the real of guide rail
Parameter, and the measurement of real-time each position can not be realized.
Summary of the invention
Technical problem solved by the invention is to utilize two groups of gyroscope acceleration sensor often groups by 1 gyroscope structure
Becoming, such two groups are separately mounted on two guide rails, it is achieved the real-time detection to the depth of parallelism of cage guide.
In order to solve the problems referred to above, the technical solution of the present invention is: be fixed on vertically by psd optical position sensitive sensors
Direction is used for determining gyro reference angle value, is then fixed on often organizing gyroscope on single guide rail, it is achieved to elevator
The Real-time Collection of guide rail data, and data will be collected be converted into digital quantity through stm32 built-in ad process, it is sent to host computer
The waveform realizing every guide rail side-play amount shows.
This device can solve the focal length of laser, the problem of short distance areal survey, also solves traditional measurement method and is subject to
It is formed on the restricted problem of survey crew level.And employ ARM7 microprocessor, it is achieved that the process real-time to data,
Make measurement equipment lighter, measure cost and reduce.
