Abstract

The invention discloses a fiber channel-based general automatic test system, and belongs to the field of automatic test. The system comprises an automatic test system and an automatic test system network. The test system consists of automatic test equipment, a test adapter, a switching network, an extended resource module and a tested unit; and detection and analysis of the tested unit are realized together. The test system network consists of a local automatic test system and a non-local automatic test system network and realizes networked test system function. The system makes full use of two properties of a fiber channel, namely input/output (I/O) channel technology and network technology. The high-speed storage performance of the I/O channel technology is used as an internal communication protocol of the automatic test system, the network performance is used as a transmission protocol of the test system network, the structure of the traditional automatic test system is accommodated under the condition that the system construction is not changed, and good compatibility is realized.

Description

technical field [0001] The invention belongs to the field of automatic testing, relates to a universal design of an automatic testing system, and in particular relates to a universal testing system based on an optical fiber channel. Background technique [0002] Automatic Test System (ATS for short) is a testing device that automatically performs process monitoring, fault diagnosis and result analysis on a unit under test (Unit Under Test, UUT for short). With the rapid development of computer and communication technology, information-based electronic equipment has become more and more complex, and it has become more difficult to perform process monitoring, fault diagnosis and processing functions on complex electronic equipment. Traditional special testing equipment can no longer meet the huge functional testing of different equipment. It is particularly important to build a generalized automatic test system. The generalized automatic test system can adapt to the test requ...
