Description

A kind of extendible intelligent disconnection control device

Technical field

The utility model belongs to automatic test technology field, relates to a kind of functional part for Auto-Test System or equipment interface adapter, specifically a kind of extendible intelligent disconnection control device.

Technical background

In the ATS of complex electronic equipment is set up, for different tested objects and test request, need to develop special test interface adapter.Adapter is the requirement that realizes fault diagnosis and fault isolation, and in signal input, output side signal face need to design manual intervention interface, due to the difference of equipment under test and testing requirement, often needs to develop special purpose interface adapter.A lot of measurands all belongs to same type, and they are often Intelligent Communications Interface difference, the difference of signal kinds and signal way, if be all designed to special test interface adapter, can cause raising cost of testing system, reduce testing apparatus utilization factor, the prolonged test system lead time.

Utility model content

The purpose of this utility model is to provide a kind of extendible intelligent disconnection controller, it is the universal intelligent manual intervention interface of test interface adapter in ATS, according to different tested objects to different testing requirements such as signal injection, picking up signal, signal isolation and kind of interface, by the setting to intelligent disconnection controller, can meet the different testing requirement of a class computerized equipment, thereby realize General design.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of extendible intelligent disconnection control device, comprise casing, it is characterized in that: on described casing, be provided with controller panel, on described controller panel, be provided with embedded computer bus interface, in casing, be provided with power protection unit and controller, described controller includes power supply interface, system interface, modulation interface, CPU module, controller module, bus driver module and isolation transceiver, wherein said CPU module and power supply interface, controller module, system interface, modulation interface and isolation transceiver connect simultaneously, described bus driver module is connected with CPU module by controller module.

Preferably, described isolation transceiver is 4.

By technique scheme, the beneficial effects of the utility model are:

1, the tailored version design that has realized interface adapter manual intervention interface transfers General design to, original technology can be merged into a universal test system for multiple detection systems of different model equipment under test, reduce system cost, improve test macro utilization factor.

2, the integrated multiple serial ports of multimode blocking, by being connected with different interface drivers, can meet the Interface Expanding demand of system.

3, interface adapter adopts modularization, General design.Adopt interrupt mode for the data processing module that needs real-time response, and the processing of communication queue adopts general fashion, system interface adopts the mode of interrupting to realize Data Update and processing; Each module can be regarded the unit working alone as, when operation, works in coordination, and completion system function.
