Abstract
The invention belongs to avionics fields, especially relate to the general acquisition and interpretation method of a kind of flight parameter, and the universal flight parameter collector using this method, flight parameter collector are fitted and fixed on collector mounting rack by the way of the docking of four rectangles.The different characteristic signal that all related systems of similar platform aircraft or sensor export is acquired by this method and product respectively according to maximization mode and domain based mode to be defined with interface, mainly the identical signal in different model aircraft is drawn and is connected to multiplex channel, unlike signal, which draws, to be connected to inequality and defines channel, to realize versatility, stability and anti-interference of the product on homologous series aircraft.
Description
Technical field
The invention belongs to avionics field, general acquisition and the interpretation side of a kind of flight parameter are especially related to
Method.
Background technique
Core product of the flight parameter collector as flight data recording system, on main harvester sensor and other
The flying quality of airborne equipment is transmitted after arranging to the data of acquisition by prescribed form by bus outward.Current Domestic Aircraft
Due to use demand difference, also numerous and complicated, the aircraft of each model need the airborne signal of acquisition and recording each to aircraft type
It is not identical, cause equipped flight parameter collector product also different, even if the hardware device of demand is the same, due to individual
Parameter type is different, and signal reduction method is different, and flight parameter collector cannot be unified for one kind, form a variety of flight parameters and adopt
Situation coexists in storage, is unfavorable for standardized production, is unfavorable for string part on machine and uses, spares reserve and allotment also have larger difficulty.
The present invention is acquired respectively using maximization mode and domain based mode and is defined with interface, and identical signal is drawn to be connected to be multiplexed and is led to
Road, unlike signal, which draws, is connected to inequality channel, and the General design of product is realized using the method that difference signal mutual exclusion defines.
Summary of the invention
Goal of the invention: the object of the present invention is to provide a kind of universal flight parameter collectors to design, to realize homologous series
The versatility of aircraft flight parameter acquisition unit.
Technical solution:
A kind of general acquisition and interpretation method of flight parameter, which is characterized in that pressed in flight parameter General collector
It handles, the inequality parameter of different model is packaged by original definition, data pass through under ground-support device respectively according to signal kinds
After load, Data Processing Ground Station parses inequality acquisition parameter according to type machine information respectively, specifically includes the following steps:
Step 1: acquiring each system of similar platform aircraft or sensor signal according to maximization mode and domain based mode point
It is not acquired and is defined with interface；
Step 2: the same acquisition of the identical signal definition of homologous series aircraft output to flight parameter General collector is logical
Road, inequality Modulation recognition are defined into the fixed area of flight parameter General collector；
Step 3: the data of acquisition and recording identify different fly according to type machine information on ground data processing platform
The signal of machine acquisition and recording completes the parsing and interpretation of each model airplane data.
A kind of universal flight parameter collector, which is characterized in that rear-mounted connector uses four rectangular configurations, flight ginseng
Number collector is connected on collector mounting rack, and with each system of aircraft by connector abutting joint, and rear-mounted four rectangle connects
It connecing device and is divided into tetra- cavitys of A, B, C, D, the acquisition signal for avoiding each system of aircraft or sensor from exporting is interfered between each other,
It is defined into different cavity body according to each signal characteristic subregion, improves the reliability and anti-interference of product；Forward type connector
Using circular configuration, it is connected with ground-support device, improves the ease for maintenance of product.
The utility model has the advantages that a kind of universal flight parameter collector realized based on signal mutual exclusion method provided by the invention,
It can be realized using identical flight parameter collector in homologous series different model aircraft, reduction uses the product by the user type, real
The mass that now produces, standardization, improve the stability and reliability of product, reduce design production cost, reduce spare part type,
It reduces and ensures difficulty, improve outfield flight parameter collector generalization degree.
Detailed description of the invention
Fig. 1 is a kind of flight data recording system functional block diagram based on universal winged ginseng collector design.
Specific embodiment
It is described in further detail below by specific embodiment is novel to the present invention:
It is as shown in Figure 1 the flight data recording system functional block diagram based on universal winged ginseng collector design.Flight ginseng
Acquisition control core product of the number collector as flight data recording system, is responsible for each system of homologous series aircraft or sensor is defeated
The acquisition of signal out.Each interface module works independently in the universal flight parameter collector, receives, acquires each system of aircraft
Different type parameter, main computer module obtain each interface module data by internal bus, pass through after collated and packing processing
HDLC bus transfer is recorded to each recording equipment.Realize that the key of product versatility is the acquisition and uniformly of front end data
Processing need to be in flight parameter collector since the information such as different model aircraft acquisition number of signals, restoring method are not quite similar
It handles, the inequality parameter of different model is packaged by original definition, data pass through ground-support device respectively according to signal kinds
After downloading, Data Processing Ground Station parses inequality acquisition parameter according to type machine information respectively.
Flight parameter collector is mounted on collector mounting rack using rear-mounted four rectangular connectors docking mode, and with
Each system of aircraft is connected.Rear-mounted four rectangular connector is divided into tetra- cavitys of A, B, C, D, to avoid each system of aircraft or sensor
Export to the types acquisition signal such as the universal winged ginseng power supply of collector, simulation, switch, HB6096, RS-422 between each other by
It to interference, is defined into according to each signal characteristic subregion in the different cavity body of four rectangular connector of collector rear panel, to improve
The reliability and anti-interference of product；It is connected using forward type cylindrical connector with ground-support device, improves the easy dimension of product
Shield property；Flying to define inside ginseng collector using Modulation recognition, unified acquisition and recording format, identical signal, which draws, is connected to multiplex channel,
Unlike signal, which draws, is connected to inequality channel, to realize the General design of flight parameter acquisition interface.
