Problems solved by technology

At present, the traditional debugging method used in China is to customize specific debugging equipment for the project, and then connect to a dedicated debugging computer for debugging and software loading. Specifically, use independent external debugging equipment and develop special test programs for separate tests. The traditional method has the following disadvantages: For different project products, it is necessary to customize special debugging equipment and develop special test programs, and the compatibility is poor, which increases repeated development work

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] 1. Composition

[0025] Such as figure 1 , figure 2 As shown, the aviation general test equipment debugging box is composed of LCD display screen, aviation socket adapter board, main control board, etc. The "main control board" is composed of: main control CPU, DDR2SDRAM, NandFlash, power circuit, LCD screen display interface circuit, GPIOs control circuit, relay matrix switching circuit, ADC sampling interface circuit and various interface sockets. The PC end communicates with the main control CPU through RS232, USB, and RJ45, and controls the switching of the relay matrix switching circuit through the GPIO interface circuit. The switched signal is connected and debugged through the socket of the main control board and the PC end. After the input 5-way power supply is conditioned by the ADC sampling interface circuit, it is input t...

Abstract

The invention discloses a debugging box for avionics universal test equipment. The debugging box includes a main control board, and the main control board includes a main control CPU, a relay matrix switching circuit and a GPIOs expansion circuit. The main control CPU receives switching signals sent by a PC terminal, and controls the GPIOs expansion circuit to switch the relay matrix switching circuit according to the switching signals, to establish a required test channel for a product under test. According to the debugging box for avionics universal test equipment, for different projects, only debugging operating software of the corresponding projects needs to be written according to a template; when the identical debugging box is used, only a corresponding debugging cable needs to be matched and then corresponding debugging software is opened at the PC terminal, and the university of a debugging device is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of avionics, and relates to an avionics universal test equipment debugging box capable of testing various display control systems. Background technique [0002] With the rapid development of the aviation industry, aircraft projects of various models and functions are increasing day by day, especially the single-function chips in the past are gradually replaced by multi-functional and high-performance chips, and the integration of products becomes higher. Generalization and generalization create favorable conditions. At present, the domestic traditional debugging method is to customize specific debugging equipment for the project, and then connect to a dedicated debugging computer for debugging and software loading. Specifically, use an independent external debugging equipment and develop a dedicated test program for separate tests. The traditional method has the following disadvantages: For different projec...
