Problems solved by technology

[0002] In the interconnection bus network of airborne avionics airborne equipment, there are a large number of data communication messages between terminal devices. During the message processing process, it is necessary to identify and store the messages in the network. The current common practice is to collect all the messages on the bus After receiving it, analyze and store it one by one, but this method takes up more hardware and software resources, making the operation very complicated and affecting the efficiency of data processing

Embodiment Construction

[0025] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0026] like figure 1 As shown, a method for fast identification and collection of airborne bus message data mainly includes four parts: avionics message serial-to-parallel conversion control, avionics message remote terminal address decoding, terminal address template data writing control, and address bit comparison control , the airborne bus message data rapid identification and collection method includes:

[0027] Step 1: the CPU writes the remote terminal address bit data template to be collected into the latch 12 through the data bus 11;

[0028] Step 2: Avionics message serial-to-parallel conversion 16, converting the serial message of the avionics bus 13 into parallel data;

[0029] Step 3: converting the 5-bit remote terminal addre...

Abstract

The invention discloses rapid airborne bus message data recognition and acquisition method, and relates to content of a message monitor and storage method for airborne equipment interconnection bus networks in airborne avionics. The method mainly comprises four parts of avionics message serial / parallel conversion control, avionics message remote terminal address decoding, terminal address templatedata writing control and address bit comparison control. According to the method, identification and screening of remote terminal data in data buses are realized by adoption of an address decoding and comparison manner according to the characteristic of remote terminal address bit identification in avionics data, so that the problem of remote terminal message discrimination in airborne bus networks is effectively solved.

Description

technical field [0001] The invention relates to the technical field of computer control, in particular to a method for quickly identifying and collecting airborne bus message data. Background technique [0002] In the interconnection bus network of airborne avionics airborne equipment, there are a large number of data communication messages between terminal devices. During the message processing process, it is necessary to identify and store the messages in the network. The current common practice is to collect all the messages on the bus After receiving them, they are analyzed and stored one by one, but this method takes up more hardware and software resources, which makes the operation very complicated and affects the efficiency of data processing. Contents of the invention [0003] The purpose of the present invention is to address the above-mentioned problems, propose a kind of airborne bus message data rapid identification and collection method, realize effective remo...
