Electronic elements testing bus automatic control device especially for digital logic and micro-command logic cards - uses micro-controller or automatic control device which is controlled by micro logic device for testing electronic components

摘要

The electronic control system uses a controller(4) controlled by microprocessor, which controls via a logic control unit(5) the testing bus(7) for testing electronic circuits(C1-C3) controlled by their microprocessor(2) without interrupting their operation. Data from the microprocessor is parallel transmitted to the control unit, and the control unit data is transmitted in parallel to the microprocessor. The control electronic device data is transmitted in series by the testing bus to the test elements, and the response of each of them is transmitted to control device along the same bus. ADVANTAGE - Is adaptable to different types of test bus, and permits testing of different electronic elements. Can be applied to all microprocessors but in association with logic cards controlled by test bus.
