Description
Technical field
The utility model relates to the elevator technology field, special relevant with a kind of elevator perpendicularity detecting apparatus.
Background technology
Along with the development of national economy, elevator has become the indispensable vehicles in people's daily life, and the quality of elevator also becomes the focus that everybody pays close attention to.Elevator closes people, fault and stops ladder, moves the elevator running quality problem such as undesired and day by day increase.For this reason, except improving elevator design, manufacture and installation quality, to supervision and inspection, periodic inspection and the current check of elevator, be also very important work.Wherein detection technique is current slightly weak link, in order to ensure elevator safety, reliable, normal operation, the detection of elevator can not rest on simple measurer and instrument and do qualified and underproof judgement by the requirement of act.std, the development of detection technique should improve the precision that detects numerical value, reduces the uncertainty of measuring system, the validity that the raising measured value is consistent with actual true value.
Traditional elevator detects generally by manually completing, and detection time is long, and process is loaded down with trivial details, efficiency is low, and the detecting instrument of developing intellectual resource has important effect for the raising detection efficiency, so the inventor designs a kind of elevator perpendicularity detecting apparatus, and this case produces thus.
The utility model content
Fundamental purpose of the present utility model is to provide a kind of elevator perpendicularity detecting apparatus, forms and has multi-functional microsystem, and measurement precisely, fast, is easy to carry simultaneously.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of elevator perpendicularity detecting apparatus, comprise obliquity sensor, microprocessor, display unit; Obliquity sensor connects the input end of microprocessor, and display unit connects the output terminal of microprocessor.
Described obliquity sensor, comprise signal gathering unit, amplifying circuit and A/D change-over circuit; Ultra-weak electronic signal signal gathering unit collected by amplifying circuit is amplified, and amplifying circuit output connects the A/D change-over circuit, through the A/D change-over circuit, inputs to microprocessor.
Described obliquity sensor, microprocessor, display unit are arranged in housing, and the mounting means of housing and UUT is magnet adsorption.
Described display unit is LED display.
The demonstration data of described display unit are 1000 times of angle of inclination tangent value.
The output terminal of described microprocessor connects alarm unit.
Described microprocessor communicates and is connected with host computer by RS-232.
After adopting technique scheme, as long as it directly is positioned over to position to be detected, because angle of inclination causes stressed difference, the F that makes a concerted effort that the sensitive element pendulum is suffered will depart from gravity value G, its output signal F value becomes linear approximate relationship within the specific limits with inclination angle theta, and signal output will keep linear output relation with this inclination angle within the specific limits.This electric signal is inputed in microprocessor and processed, through converting, draw angle of inclination.The utility model measuring accuracy is high, light portable, easy to operate, cheap.
The accompanying drawing explanation
Fig. 1 is the utility model preferred embodiment module diagram;
The module diagram that Fig. 2 is the utility model preferred embodiment obliquity sensor;
Fig. 3 is measuring principle schematic diagram in the utility model preferred embodiment.
Embodiment
By reference to the accompanying drawings, to the utility model, preferred embodiment is described in further details.
A kind of elevator perpendicularity detecting apparatus, the functional module mainly comprised as shown in Figure 1, obliquity sensor 1, microprocessor 2, display unit 3, alarm unit 4, host computer 5.
The principle of obliquity sensor 1 as shown in Figure 3, adopts " solid pendulum " formula structure to be measured in the present embodiment, when the position of detecting has tilt angle theta, the solid pendulum, it is comprised of pendulum 71, cycloid 72, support 73, and pendulum 71 is subject to the effect of gravity G and pendulum pulling force T, and its bonding force is F.Wherein, the angle that θ is cycloid and vertical direction.While measuring, can think that F and θ are linear in small angle range.The pumping signal produced by signal source is added on pendulum, if sensor in plumbness, pendulum is in plumbness, signal is output as zero; When it tilts to a direction, the F that makes a concerted effort changes, and F and θ are linear, as long as collect like this value of F with joint efforts, just can draw the θ angle of inclination.
Microprocessor 2 can adopt at present the single-chip microcomputer of maturation on the market, carries out the processing to signal on obliquity sensor 1, according to the linear relationship of F and θ, finally draws θ.In order to ensure detecting precision, 4/1000 and 2/1,000 two critical gradient is set, the 4/1000 critical gradient as elevator traction sheave, the 2/1000 critical gradient as angle sheave and governor sheave in the inside of microprocessor 2.When the elevator diverse location surpasses critical gradient, the alarm unit 4 connected by microprocessor 2 is realized reporting to the police, and type of alarm can be multiple, such as buzzer warning, or the alarm lamp flicker etc.In the present embodiment, connect LCD display on microprocessor 2 as display unit 3 simultaneously, the data that detect are shown.
In addition in order to make remote monitoring, and data transmission is convenient, and the RS-232 that passes through on microprocessor 2 communicates and is connected with host computer 5.
When the utility model is used, obliquity sensor 1, microprocessor 2, display unit 3 are arranged in a housing, and the mounting means of housing and UUT is magnet adsorption, simple operation like this.Obliquity sensor 1 directly can detect angle of inclination, then it is changed into to electric signal and inputs in microprocessor 2 and processed, and by it, calculates the angle of inclination value, on LCD display, is shown.The utility model is used simple to operate, easy to carry, and precision is high.
Above-described embodiment is only for the inventive concept of the present utility model of explaining, but not to the restriction of the utility model rights protection, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should fall into protection domain of the present utility model.
