Embodiment Construction

[0073] The present invention will be further elaborated below in conjunction with embodiment.

[0074] Such as figure 1 As shown, the tester in the present invention includes: an industrial computer, a switching box, an insulation withstand voltage tester, and a cable. The industrial computer is used to realize the operation of the test system and obtain the test results; among them, the main control module sends instructions to other functional modules and processes the return instructions of other modules; the CAN communication module realizes the communication between the industrial computer and the switching box Communication; multimeter measurement module to collect measurement results. The switching box receives, analyzes and executes relevant operation instructions from the main control module; among them, the function switching module analyzes the instructions sent by the main control module, and sends the analyzed information to the test point switching module; the t...

Abstract

The invention relates to a comprehensive self-checking method of an automatic tester. The tester comprises an insulation and voltage resistance tester, a plurality of switching boxes, a main control module and a universal meter measurement module, wherein the main control module and the universal meter measurement module run on an industrial personal computer; a function switching module and a test point switching module connected with a tested point run in each switching box; and the main control module sends instructions to the function switching modules, the function switching modules analyze the instructions and send the instructions to the test point switching modules, and the function switching modules and the test point switching modules control on-off of related relays according to the instructions to realize self-inspection, and the self-inspection comprises conduction self-inspection, short circuit self-inspection, insulation self-inspection, anti-electricity self-inspection, switching box self-inspection and relay residual life self-inspection. According to the comprehensive self-checking method of the automatic tester, the detection coverage is wide, the accuracy of subsequent testing is ensured, and a guarantee is provided for normal use of equipment.

Description

technical field [0001] The invention relates to the field of automatic testing, in particular to a comprehensive self-checking method of an automatic testing instrument. Background technique [0002] The automatic tester is widely used in the fault detection of large-scale equipment and complex cable network, and it can find potential problems of equipment early. The performance index of the automatic tester itself is the prerequisite for other equipment testing. However, most of the current research on automatic testers is in the scope of their tests, and they have not fully detected their own possible faults. Contents of the invention [0003] The technical problem solved by the present invention is: to provide a comprehensive self-inspection method for an automatic tester, capable of fully automatic and full-coverage detection of the tester's own functions, ensuring that the automatic tester's own performance indicators are qualified, and does not affect the testing of...
