Summary of the invention
Technology of the present invention is dealt with problems: overcome the deficiencies in the prior art, a kind of data conversion system based on carrier aircraft platform is provided, this system is easily implemented in engineering, can the mutual conversion of data layout effectively between implementation platform simulating signal and digital signal and level.
First the reference voltage of AD device MAX191 in interface adapter is exported to air computing machine, interface adapter is returned after the slide rheostat of air computing machine, after AD conversion, variation relation according to its return voltage and reference voltage calculates its resistance change rate, thus obtain current carrier aircraft height according to the corresponding relation of resistance change rate and air height, and be converted to ARINC 429 data that airborne collision avoidance system can receive.
Technical solution of the present invention: a kind of data conversion system based on carrier aircraft platform, its feature is high-precisionly to calculate current platform air altitude information, wherein:
Processor receives the analog sampling signal from A/D chip in processing procedure, be treated to air altitude information, for ensureing data correctness, need by smoothing for AD sampled data algorithm, prevent altitude information saltus step on a large scale, be the ARINC 429 agreement recompile of 203 according to No. Label by air altitude information, and the step-by-step of control ARINC 429 protocol conversion chip exports, the time interval is 35 ~ 50 milliseconds simultaneously.

Arbitrary feature disclosed in this instructions (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
As shown in Figure 1, for ensureing the interchangeability requirement of interface adapter, the reference voltage exporting air computing machine to have employed the internal reference voltage of AD device MAX191, this builtin voltage is used because MAX191 is same in AD sampling process, when chip self difference may be there is and causes reference voltage to have a nuance in this builtin voltage, sampled level amplitude is divided into 4096 parts by chip itself, therefore different MAX191 is in the reference voltage situation in conjunction with self, (example: different two panels MAX191 that the reference voltage nuance existed also can be eliminated on year-on-year basis, output reference voltage is respectively 4.096V and 4.1V, its every a amplitude of samples is for being respectively 0.001V and 0.0010254V, it is 4096 on year-on-year basis), thus ensure sampling precision consistance, improve air altitude information processing accuracy, meet interchangeability requirement.In order to ensure the interchangeability of interface adapter on identical machine, just require that the reference voltage exporting air height computer to is accurate, in interface adapter, have employed the device MAX191 internal reference voltage of MAXIM company as the reference voltage exporting air computing machine to.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature of disclosing in this manual or any combination newly, and the step of the arbitrary new method disclosed or process or any combination newly.
