Abstract

The invention relates to an automatic test system which comprises a host unit and an intelligent test bed, wherein the host unit is connected with the intelligent test bed through a data wire and comprises an execution control module, a communication module and a scheme configuration module; test equipment comprises a plurality of power sources, a plurality of error plates, a serial port server, a reference clock source, a standard table and a plurality of meter positions; the multiple meter positions are used for mounting of external meters to be tested; each power source and each error plate are arranged at each meter position; the power sources and the meter positions are the same in number; a test configuration file generated by the scheme configuration module sends a control instruction to the serial port server through the communication module; the serial port server receives a pulse signal emitted by the reference clock source and sends the control signal to the power source, the error plate and a standard meter which correspond to each meter position, thus simultaneously finishing control on parameters corresponding to the power source, the error plate and a standard meter which correspond to each meter position.

Description

technical field

[0001] The invention relates to the field of power meter production, in particular to the post-production test of the power meter. Background technique

[0002] With the rapid expansion of computer application fields, computer programming technology can be used to realize batch automatic testing and replace heavy and repetitive manual testing, thereby greatly improving the efficiency of testing. In the power industry, there are many traditional power terminal products, which are divided into electric energy meters, electric energy meter intelligent data collectors (referred to as: collectors), intelligent data concentrators (referred to as: concentrators), distribution transformer monitoring and metering terminals ( Abbreviation: distribution transformer), these devices are divided into many models. In order to meet the needs, major domestic instrument manufacturers will design, develop and produce different types of equipment or the same equipment but diffe...

Embodiment 3

[0041] see again figure 2 .

[0042] The invention provides a test method for an automated test system, comprising the steps of:

[0043] S1: Place the meter under test

[0044] The external instrument to be tested is placed on the table position; the initialization button is pressed, and the initialization button generates a trigger signal, and the trigger signal is sent to the executive through the communication link generated by the serial server and the communication module. control module.

[0045] S2: Smart test bench initialization

[0046] The execution control module calls the test scheme file generated by the scheme configuration module, and the execution control module, according to the test configuration file, uses the serial port server for the power source, error board, The standard board and the reference clock source send initialization control commands.

[0047] S3: Start testing the external instrument under test

[0048] Press the test button, the tes...
