Integrated Recorder Test System

Abstract

The invention provides a protective comprehensive recorder testing system, and aims to provide a testing system, which has high testing property and a powerful function and is convenient to use. According to a technical scheme for implementing the testing system, a computer combination system is electrically connected with an adapter box combination system, the adapter box combination system is used for transmitting a signal from a testing socket to a driving panel combination (19) or a back panel socket through an internal connecting line to finish transmission of a tested signal of a comprehensive recorder, the testing signal entering a driving panel passes through a conversion circuit in the driving panel, and a signal-end low-voltage signal coming from a tested crash survivable memory unit (CSMU) and a central processing unit (CPU) is converted into a double-end differential signal inside the comprehensive recorder performance testing system; a low-voltage signal-end differential signal of the tested CPU enters the testing socket through a testing tool, and a PSU (Program Storage Unit) testing tool (24) ad a CPU testing tool (27) are used for switching the tested signal to the driving panel combination system and testing software in order to realize testing of two paths of direct-current output signals and testing of 16 paths of discrete magnitude signals.

Description

technical field [0001] The invention relates to a test system for a protective integrated recorder, especially capable of testing the protective integrated recorder (ISR), the power supply unit (PSU), the central processing unit (CPU), and the anti-crash component inside the protective integrated recorder. (CSMU) and CPU chip for functional and performance testing test system. Background technique [0002] The test equipment widely used in the prior art is a test with single function, single display mode, simple man-machine interface, poor readability, and lack of versatility and expandability. Usually, the equipment under test protection type comprehensive recorder is composed of anti-crash component CSMU, central processing unit CPU and power supply component PSU. The test equipment needs to carry out ISR test, power supply component test (PSU test), central processing unit component test (CPU test), anti-crash component CSMU test (CSMU test) and central processing unit c...

AI Technical Summary

Problems solved by technology

Generally, the test system for testing the above-mentioned equipment mainly developed by a single-chip computer cannot meet the requirements of the protective comprehensive recorder when testing the power supply components, central processing unit components, anti-crash components and CPU chips inside the protective comprehensive recorder. device testing requirements

This kind of single-chip microcomputer hardware and software platform with single function needs to develop component test equipment when component testing is needed. If there are several components, it is necessary to develop several component test equipment. In this way, on the one hand, it brings development costs and The result of high management costs, on the other hand, not only increases the size of the test equipment, which is not conducive to product debugging and fault diagnosis, but also cumbersome operations, low efficiency, and increased costs
