Afterwards the gradient of car floor not should be greater than its entopic 5%.Peace is weighed in GB7588-2003 with car inclination angle
Full clamp brake synchronization extent.The instrument at existing measurement angle of inclination, is all only applicable to static measurement, i.e., only can be in measured object
Its angle of inclination is measured when body remains static, it is impossible to it is surveyed when testee is kept in motion
Amount.This causes that existing device cannot carry out effective dynamic measurement to the gradient of car floor in elevator safety gear action,
And then so that the regulation on the gradient of car floor after safety tongs action in standard GB/T 7588-2003 is in and leaves unused
State.Tester only can carry out subjective judgement to the gradient of car floor after safety tongs action, and can not be by instrument
Accurately measured.
The content of the invention
Surveyed it is an object of the invention to provide a kind of gradient easy to use, can be during exercise to car floor
Amount, and the accurate elevator safety clamp brake dynamic synchronization tester of test result.
To achieve the above object, elevator safety clamp brake dynamic synchronization tester of the invention include housing, single-chip microcomputer and
3-axis acceleration sensor, single-chip microcomputer is connected with power supply and display device, single-chip microcomputer be provided with the first I/O interface, the second I/O interface,
3rd I/O interface, SCL pins and SDL pins；First I/O interface is connected with by compressing switch, and second I/O interface connects institute
State display device；3rd I/O interface is connected with the bluetooth module for outwards installing preparation censorship measurement information；Three axle
Acceleration transducer is provided with SCL pins and SDL pins；The SCL of the SCL pins connection 3-axis acceleration sensor of single-chip microcomputer draws
Pin, the SDL pins of single-chip microcomputer connect the SDL pins of 3-axis acceleration sensor；
The single-chip microcomputer, 3-axis acceleration sensor and power supply are respectively positioned on enclosure interior, and the display device is embedded on housing.
The surface of shell is provided with groove, and the display device is embedded in the groove；The surface of display screen and housing table
Face is flush.
The display device is liquid crystal input and output expansion board, and liquid crystal input and output expansion board includes display screen and keyboard,
Keyboard is located at the lower section of display screen and is embedded on housing.
Simple structure of the present invention, is easy to movement, easy to use.When using, place this invention on lift car floor, beat
Open by compressing switch, then carry out safety tongs braking maneuver.Now single-chip microcomputer continuous firing under the power supply of power supply.Safe clamp brake
Afterwards, if car floor is inclined must cause 3-axis acceleration sensor run-off the straight, 3-axis acceleration sensor leads to signal
Cross SCL pins and SDL pins pass to single-chip microcomputer, single-chip microcomputer shows on the display apparatus the angle of inclination of car, measurement knot
Fruit is more accurate.Bluetooth module can easily by detection information of the invention（The dynamic of car floor after safe clamp brake
Angle of inclination information）Send external equipment to, such as carry computer, mobile phone, the flat board equipment of Bluetooth receiving function, enter one
Step facilitates operating personnel to monitor detection process by external device.In current social, people very get used to mobile phone, flat board and
Computer, the equipment of bluetooth module is highly convenient for the present invention and is connected with these equipment, makes the use habit of the present invention and people
It is relative to connect, it is easy to popularization and application of the invention.
Structures shape of the invention its small volume, after measurement terminates, again can easily by the present invention from car
In take out of.
If display screen protrudes housing, it is easy for being subject to the collision and impact of external items；The surface of display screen and housing
Surface is flush, and has both facilitated the outside display data of display screen, and serve protective effect to display screen.
