Problems solved by technology

When the on-site spare parts need to be used in an emergency, if it is impossible to confirm whether they are available due to long storage time or storage environmental factors, if they return to the factory for testing, the operation of the equipment will inevitably be affected in time, so it is necessary to be able to confirm the order at the operation site board availability

Embodiment Construction

[0018] Taking the SIMADYN D board as an example to illustrate the board test system of the present invention, the system includes a cabinet, a test computer (PC workstation), a test host module and a man-machine interface module. The test host module mainly completes the realization of the test principle of the board under test, tests the main functions of the board under test to determine the usability, and realizes the construction of the test standard signal source at the same time. The man-machine interface module realizes the data interaction between the test PC and the test host, realizes the collection and storage of test data, and can perform the calibration operation of the standard signal source.

[0019] At present, the types of SIMADYN D boards running in the control and protection equipment of the DC transmission system can be basically divided into five types: processor board, memory card, IO board, communication board, and optical technology measurement board:

Abstract

The invention relates to a board card test system. The system comprises a cabinet, a test computer, a test host module and a man-machine interface module, wherein the cabinet comprises a standard board card and a replaceable board card, and is used for inserting a board card to be tested; the test host module is arranged in the standard card in the cabinet and used for testing the main function of the board card to be tested, so as to determine the usability and construct a test standard signal source; and the man-machine interface module is arranged in the test computer and used for realizing the data interaction between the test computer and the test host module, so as to realize the collection and storage of test data and calibrate the standard signal source. In the invention, the complete standard operation system which is capable of testing five types of board cards is constructed; and when in use, the test system can directly test a single board at a client site without any special devices and the limitations of the environment and the device, so that the verbose process that board cards are tested after being returned to the factory is omitted, the time is saved and the operation of the device can not be influenced.

Description

technical field [0001] The invention relates to a board test system. Background technique [0002] SIMADYN D system is a scalable hardware platform based on backplane bus and multi-processor. Since 2000, the control and protection equipment in the domestic HVDC transmission system has adopted the technology with SIMADYN D as the hardware platform. The wide use of SIMADYN D in the field of direct current transmission makes the maintenance and management of its spare parts more and more important. [0003] The testing of single boards in the factory is very strict and the procedure is very complicated, which requires the factory's process and quality assurance measures. However, it is very difficult to use the factory's testing technology to test the single boards at the customer's site, which is limited by the environment and equipment, and even impossible. When the on-site spare parts need to be used in an emergency, if it is impossible to confirm whether they are availab...
