Embodiment Construction

[0042] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0043] The present invention adopts the object-oriented software development thinking because the protection measurement and control device that adopts DSP processor all adopts modular design and encapsulation, so for the factory debugging of protection measurement and control device, it is mainly to CPU and peripheral circuit (AC input circuit) , Communication circuit, open-in and out-circuit, operating circuit and man-machine interface) reliability detection. The present invention frees debuggers from cumbersome procedures through the modular design of the software structure and test flow, and turns it into a fast and efficient automatic test of the assembly line.

[0044] Each assembly line test sets the test station according to the test items...

Abstract

The invention discloses a DSP-based assembly line autotest method of a protection and monitoring device. The method specifically comprises the following steps that (1) one or more test items are selected by debugging personnel through a menu, and each test item comprises an alternating current sampling board test, a communication board test, an input and output board test, an operation panel test and a human-machine interface test; (2) as for the selected test items, test boards corresponding to the selected test items are connected with the protection and monitoring device to be tested; (3) after the tests of the selected test items are finished, test results of the protection and monitoring device are output through a human-machine interface, wherein if it is prompted that the tests are passed, it is indicated that the protection and monitoring device is up to standards and can be put in storage, if it is prompted that the tests are abnormal, troubleshooting is conducted on the protection and monitoring device. According to the DSP-based assembly line autotest method of the protection and monitoring device, a complete-machine test or a single-board test can be selected according to requirements, the test mode is flexible, a test of qualification or disqualification is judged through software, the interference caused by human factors is reduced, and the debugging efficiency and the quality of the protection and monitoring device are improved.

Description

technical field [0001] The invention relates to a DSP-based automatic test method for a pipeline of a protection measurement and control device, belonging to the technical field of power system automation. Background technique [0002] Due to the powerful functions of the protection measurement and control device, the debugging process is relatively complicated. For the factory commissioning of the protection measurement and control device, every test link requires the commissioning personnel to repeat the wiring, then increase the amount of test, and finally judge whether the product is qualified by comparing a series of standards. The inspection process is cumbersome, repetitive, and inefficient, and the technical level of the debugger directly determines the overall level of the product. [0003] The emergence of DSP (Digital Signal Processor) has brought revolutionary significance to the protection and control devices of the power system. It makes the calculation speed ...
