Description
Technical field
The utility model relates to aircraft weight fields of measurement, is specifically related to a kind of aircraft weight and center of gravity Smart Instrument for Measuring.
Background technology
China's exploitation aircraft weight and center of gravity monitoring equipment are started to walk comparatively early.Early 1980s, a kind of electronic weighing appliance had once filled up the blank that in China's aeronautical engineering, aircraft maintenance is weighed, and also had other aircraft weighting systems to come out.This kind of localized equipments once obtained applying of certain limit in aircraft maintenance field, and especially the lightweight aircraft of the military and part aircraft factory were once the main users of this kind equipment.But they fail to enter aircarrier aircraft maintenance industry substantially.According to analysis, because these equipment have employed by apical pore under aircraft abdomen as hard point bar none, between apical pore and bearing rod, use wheel spoke type sensor as measurement component, promoting aircraft by hydraulic jack is the mode that sensor is weighed.Although it is simple that this form has system architecture, the feature that number of sensors is few and cost is low.But the lifting distance due to 3 hydraulic jack is difficult to ensure accurate synchronization, and the angular force component often produced makes sensor weight bearing situations occur error, and hidden danger therefore in operation is larger.Especially to the aircraft of weigh tens tons and even hundreds of tons, because will be promoted by 3 hydraulic jack, the wheel spoke type sensor contacted under push rod completes measurement under stable loaded state with the bulb of aircraft apical pore to make to be positioned at push rod, and sensor cannot get involved the firm aircraft of any secondary safety measures when load-bearing.When measurement terminates, 3 hydraulic jack need steadily synchronously to drop to sensor load removal.There is the unsafe factor being difficult to expect in whole operating process.
Summary of the invention
The purpose of this utility model is to solve the problem, and provides a kind of aircraft weight and center of gravity Smart Instrument for Measuring.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of aircraft weight and center of gravity Smart Instrument for Measuring, comprise front wheel electronic scale, main wheel electronic scale, hoistable platform, laser ranging unit, aobvious control unit, laser ranging unit sends data to aobvious control unit, aobvious control unit sends control signal to hoistable platform, the lifting that hoistable platform provides signal adjustment hoistable platform according to aobvious control unit realizes aircraft horizontal adjustment, wheel electronic scale and main wheel electronic scale and laser ranging cell data carries out weight and then center of gravity calculation shows before the collection of aobvious control unit.
Described laser ranging unit is that the difference in height data of aircraft left-right and front-back measurement point and horizontal parallel data are sent to aobvious control unit by laser range finder.
The beneficial effects of the utility model are: solve that current aircraft weight center of gravity measurement workload is large, efficiency of weighing is not high, improve the problems such as accuracy is difficult to and equipment applicability is not strong.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
