Embodiment Construction

[0032] The invention proposes an automatic test scheme of the ARINC659 bus, which solves the requirements of large demand, complex functions and high safety in the batch application of the current ARINC659 bus, and improves the test efficiency and application range of the ARINC659 bus.

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] figure 1 The system test plan of the present invention is given, including: RS232 serial port module, main controller module, power supply module and tested ARINC659 module.

[0035] The RS232 module is used to complete the information interaction between the upper computer and the test system. The main controller module sends the test options to the upper computer through the RS232 module, and the user can select the test option through the super terminal in the upper computer.

[0036] The main controller module receives the test options from the host computer, selects the ...

Abstract

The invention discloses an automatic testing system for ARINC659 buses, and can solve the problem of in-batch testing of the ARINC659 buses. The automatic testing system has a complete testing function, is simple to operate, and provides an effective testing means for wide popularization and application of the ARINC659 buses. The automatic testing system for the ARINC659 buses is characterized in that according to a testing scheme, the system comprises an RS232 serial port module, a main controller module, a power supply module and tested ARINC659 modules. The RS232 module is used for completing information interaction between an upper computer and the testing system, a user can select testing options by a hyperterminal in the upper computer, and the RS232 module sends the testing options to the main controller module. The main controller module receives the testing options from the upper computer, selects the tested modules according to the testing options, and completes full-function testing for each tested module. The power supply module is used for generating all tertiary power supplies required by the testing system.

Description

technical field [0001] The invention relates to the field of system-level testing, in particular to the field of testing buses in aviation systems. Background technique [0002] The ARINC659 bus is a data bus proposed by HoneyWell and successfully applied to the aircraft information management system of Boeing 777. It has the characteristics of high throughput, strict fault isolation, and definite data transmission. High-integrity backplane bus with high fault tolerance and robustness on and space (storage space). Due to the high security and high reliability of this bus, it has been used in many domestic aircraft models, and the demand is showing a trend of increasing year by year. [0003] The ARINC659 module is to improve the versatility of the ARINC659 bus. Based on the ARINC659 bus protocol, it develops a circuit module that realizes the bus physical layer and data link layer functions. Due to the large demand, complex functions and high security requirements of this ...
