Abstract

The invention discloses automatic test equipment. According to the equipment, an industrial personal computer is used for sending a network message, controlling to-be-tested equipment to act, to the to-be-tested equipment and receiving feedback data of the to-be-tested equipment; the industrial personal computer sends data to a 1553b interface of the to-be-tested equipment through a 1553b interface, and the data is used for testing the 1553b interface of the to-be-tested equipment 8; the industrial personal computer sends data to an rs422 interface of the to-be-tested equipment through an rs422 interface, and the data is used for testing the rs422 interface of the to-be-tested equipment; the industrial personal computer tests a parallel input/output interface of the to-be-tested equipmentthrough a PCI-1762 switching value input/output board; a one-path serial interface of the industrial personal computer is connected with a corresponding multi-path serial interface of the to-be-testedequipment through an IO test box, and the IO test box switches on the serial interface of the to-be-tested equipment according to an instruction of the industrial personal computer; and a GPS test box converts a GPS signal of a GPS antenna into a differential signal and inputs the differential signal into a second pulse interface of the to-be-tested equipment.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to an automatic testing equipment. Background technique [0002] For some special-purpose computer products, the application is more extensive, the output is very large, and there are many functions, and the testing process is complicated and cumbersome. With manual testing, it takes several hours to test a computer, which consumes a lot of labor costs, and the product progress is often lagging behind; and manual testing is highly involved, and errors or missing test items are inevitable. , product quality is difficult to be guaranteed. In view of the above problems, a special test equipment with a high degree of automated testing is needed to achieve the purpose of improving test efficiency and ensuring product quality. Contents of the invention [0003] The purpose of the present invention is to provide a host monitoring system based on a plug-in architecture, which is used to...
