Problems solved by technology

At present, due to the different use requirements of domestic aircraft, the types of aircraft are also complicated. Each type of aircraft needs to collect and record different aircraft signals, resulting in different flight parameter collector products, even if the required hardware equipment is the same. , due to the different types of individual parameters and different signal restoration methods, the flight parameter collectors cannot be unified into one type, resulting in the coexistence of multiple flight parameter collectors, which is not conducive to standardized production, not conducive to the use of serial parts on the aircraft, and spare parts storage and allocation are also relatively difficult. great difficulty

Embodiment Construction

[0012] The novel of the present invention will be described in further detail below by means of specific embodiments:

[0013] Such as figure 1 Shown is the functional block diagram of the flight data recording system designed based on the general-purpose flight reference collector. As the core product of the acquisition and control of the flight data recording system, the flight parameter collector is responsible for collecting the output signals of various systems or sensors of the same series of aircraft. Each interface module in the general-purpose flight parameter collector works independently to receive and collect different types of parameters of each system of the aircraft. The main computer module obtains the data of each interface module through the internal bus, and transmits it to each recorder through the HDLC bus after sorting and packaging. device to record. The key to realizing product generalization lies in the acquisition and unified processing of front-end...

Abstract

The invention belongs to the field of avionics, and particularly relates to a universal collection and interpretation method for flight parameters and a universal flight parameter collector adopting the method. The flight parameter collector is installed and fixed to a collector installation frame by adopting a four rectangle butt joint mode. According to the method and product, different featuresignals output by all related systems or sensors of similar platform aircrafts are collected and subjected to interface definition according to a maximized mode and a regional mode separately, same signals in different types of aircrafts are led to a multiplex channel, and different signals in the aircrafts are led to a mutually different definition channel, so that the universality, the stabilityand the anti-interference performance of the product on the same series of aircrafts are achieved.

Description

technical field [0001] The invention belongs to the technical field of avionics, and in particular relates to a general acquisition and interpretation method of flight parameters. Background technique [0002] As the core product of the flight data recording system, the flight parameter collector mainly collects flight data from on-board sensors and other airborne equipment, sorts the collected data according to the specified format, and transmits them externally through the bus. At present, due to the different use requirements of domestic aircraft, the types of aircraft are also complicated. Each type of aircraft needs to collect and record different aircraft signals, resulting in different flight parameter collector products, even if the required hardware equipment is the same. , due to the different types of individual parameters and different signal restoration methods, the flight parameter collectors cannot be unified into one, resulting in the coexistence of multiple ...
