A whole machine intelligent testing method and system for a power system protection device

Abstract

The invention discloses an electric power system protective device whole machine intelligent test method and system, which can automatically throw the handle seat of a device power supply and triggers a scanner to scan the device bar code through sensing whether the device is stably arranged in the appointed position. An intelligent control center obtains a real test module name and board card control data through a local mapping database according to the attribute of the device; a driving board card switching mechanism makes adjustment according to the configuration of the hardware of the device and automatically realizes the secondary mapping of the physic connection line; the intelligent test control center automatically enters the whole machine test mode and performs the accuracy calibration or verification; the system is provided with two independent modules, wherein one is on the left and the other one is on the right, for a main and standby test; when the accuracy calibration on the left side is finished, the right side is automatically driven to perform scanning and testing, which realizes the 0 waiting in the testing time. The whole process realizes the intelligent guidance and control of the discretization test flow, effectively reduces the test labor intensity and complexity, and greatly improves the test efficiency for mass batch of the whole machine production.

Description

technical field [0001] The invention relates to the field of complete machine intelligent testing of power system protection devices. It is suitable for mass production testing of power system secondary protection devices. Background technique [0002] In recent years, the rapid development of world power grid construction has driven the rapid growth of power secondary equipment. The wide application of microcomputer protection devices has made microcomputer protection manufacturers overwhelmed: one is to increase production capacity, and the other is to expand the recruitment of a large number of production testers. At the same time, they have to reconsider the original manual test method to greatly improve production test efficiency. , in order to reduce the increasingly high cost of labor expenditure. [0003] The manual testing process is cumbersome, the testing is complicated, the efficiency is low, there are no testing specifications to follow, and the power protecti...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems of mass production and testing of existing protection devices: too many testing links and discrete processes; too many power-on times in the entire testing process, which wastes time; the proportion of manual testing links is too large; there is no specification for testing low test efficiency, etc., a method and system for intelligent testing of power system protection devices are proposed

The invention effectively solves the problem of connection control of test lines with different optional boards for the same slot number, the problem of continuous control of discrete test behavior of a single device, the problem of automatic identification from device order information to test modules, and the problem of multiple device tests. Continuous control problems, etc.
