Abstract

The invention provides a metering automatic testing device, which comprises a main controller, a data collecting unit, a first testing unit, a second testing unit, an analyzing unit and a data communication unit, wherein the data collecting unit, the first testing unit, the second testing unit, the analyzing unit and the communication unit are respectively connected with the main controller; the data collecting unit is used for collecting front end data; the first testing unit is used for simulating the terminal function test; the second testing unit is used for testing a communication protocol; the analyzing unit is used for detecting and analyzing a fault; the data communication unit is used for transmitting data; the main controller consists of an ARM chip, a data storage chip and a chip peripheral circuit; the data collecting unit comprises a plurality of PT / CT sensors and an AD (analog to digital) converter, and the AD converter is arranged between the PT / CT sensors and the main controller; the first testing unit, the second testing unit and the analyzing unit respectively consist of a DSP chip and a peripheral circuit thereof, and are integrated on one PCB (printed circuit board); the data communication unit comprises a wired communication module and a wireless communication module which are integrated on another PCB. The metering automatic testing device has the advantages that multiple testing functions can be realized, and the testing result can be automatically compared and analyzed.

Description

technical field [0001] The invention relates to the technical field of power equipment testing, in particular to an automated metering testing device. Background technique [0002] At present, most of the power terminal tests are done manually. The testers execute the test step by step according to the steps described in the reviewed test cases, compare the actual results with the expected results and draw conclusions, and finally record the conclusions Manually recorded. Even if automatic testing is realized through automated equipment, the testing function is single, and automatic comparison and analysis of test results cannot be performed. [0003] Therefore, there is an urgent need for a metering automatic testing device, which can realize multiple testing functions and can automatically compare and analyze the testing results. Contents of the invention [0004] The technical problem to be solved by the embodiments of the present invention is to provide an automatic ...
