Abstract

The invention discloses a test system based on an universal interface board of a VxWorks system. The test system comprises an upper computer, a to-be-tested interface board and a bottom board; the to-be-tested interface board is connected with the CPCI connector on the bottom board through the CPCI connector, and the bottom board communicates with the upper computer through the Ethernet. The VxWorks6.9 operating system creates an interactive receiving task and an interactive sending task with an upper computer; the priority of the receiving task is set as high priority 99, a control and communication instruction including an initialization instruction, a data sending instruction and a data receiving instruction for receiving each drive sent by an upper computer are used, the instruction inthe receiving task is analyzed, and a processing function is called for processing after the instruction is obtained; the priority of the sending task is set to be higher than 98, and data sent by other nodes of the peripheral driver is sent to the upper computer through the task for testing of the upper computer. According to the invention, the test efficiency and the test reliability of the universal interface board are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of automated testing, and relates to a testing system based on a VxWorks system universal interface board. Background technique [0002] Interfaces such as 1553B bus, CAN bus, serial port, digital input and digital output are common interfaces in the aerospace field. In order to meet the requirements of generalization and scalability, these interfaces are usually integrated into a board. An integrated system of different functions. Traditionally, the debugging of interface boards needs to write specific test software according to specific interfaces. The test process usually requires placing the boards in a chassis or cabinet, and connecting the actual peripheral nodes or related bus analysis tools externally for sending and receiving tests. , this method depends on the reliable physical connection between the chassis and the interface board, and is limited by the form of the physical interface of the chass...
