Description

Technical Field

[0001] The present invention relates to the technical field of electric energy meter data testing, and in particular to an automated virtual meter platform and method for simulating an intelligent device acquisition environment. Background Art

[0002] With the increase in the types of data acquisition terminals for electric energy meters and the improvement of data acquisition process and processing requirements, the on-site meter reading environment has become increasingly complex. Traditional test methods are difficult to simulate the complex meter environment on site, such as carrier meter networking failure, abnormal data item response, etc. The actual environment is difficult to build and fixed, and cannot meet the test requirements of various types and a large number of electric energy meters required for testing, as well as the requirements of simulating various abnormal situations.

[0003] In the existing test methods, if a small number of simple electric energy meters are used for testing, the test of the electric energy meter data acquisition terminal can be barely achieved manually, but the efficiency is low. When simulating the field environment and conducting stress testing, the test requirements are complex and require a lot of human resources and time. In addition, the test cases cannot be converted into automation, resulting in a lot of repetitive work for testers. The existing test methods cannot flexibly configure test scenarios, such as changing meter types, meter reply data values, abnormal responses, etc. These test requirements are difficult to achieve in the actual environment and cannot be completed by simple test tools or methods, which limits the effectiveness and reliability of the test. In addition, due to the complexity and variability of the field environment, the existing automated test methods are greatly limited in practical applications. Automated test tools often cannot adapt to complex field environments, resulting in inaccurate test results or inability to complete test tasks.

[0004] In view of the above problems, an automated virtual meter platform and method for simulating the intelligent device acquisition environment are designed to solve the above problems. The on-site meter reading environment is simulated in a virtualized way, and the flexible configuration of test scenarios is achieved, the test efficiency is improved, and repetitive work is reduced. It also promotes the application of automated testing in the test of electric energy meter data acquisition terminals, which has important practical significance. Summary of the invention

The automation master station platform directly calls this database when comparing meter reading data; in order to more conveniently understand the detailed functions of the automated virtual table platform, the following three main parts are listed:

[0074] (1) Functional category: narrow-bandwidth mode switching, blacklist test;

[0075] Narrow-bandwidth mode switching: Switch between meter reading modes for different carriers. When narrowband carrier communication is selected, the virtual meter platform replies that the communication mode is 1. When broadband carrier communication is selected, the virtual meter platform replies that the communication mode is 2.

[0076] Blacklist test: For the table test that is not connected to the network on site, blacklist processing is added. The virtual table platform will not reply to the slave node selected in the blacklist or reply F101 without carrying data;

[0077] (2) Commands: configure walking characters, configure loop setting data items, configure single and three phases, configure data item exceptions;

[0078] Configuration of the data: By setting the minimum and maximum values ​​of the data, setting the jump time and jump value, simulate the field meter data

[0079] Configure loop setting data items: By loop setting the freezing time interval, the loop setting data items simulate the stress test under long-term operation time on site.

[0080] Configure single-phase and three-phase: Differentiate the data structure of different types of meters by configuring single-phase and three-phase. When set to a three-phase meter, it supports variable assignments such as A\B\C phase voltage and current. When set to a single-phase meter, it only supports variable assignments such as A phase voltage and current.

[0081] Configuration data item exception: It is used to simulate the inconsistent data response of meters from different manufacturers in complex on-site environments. You can configure table 698 to respond to DAR type, table 645 to respond to empty value, no response, or response to abnormal D101 (D201, etc.).

[0082] (3) Enablement class: configure preamble, configure delayed reply, configure module ID, and configure phase information.

[0083] Configure the preamble: The test meter reply carries the preceding frame (FE FE FE FE).

[0084] Configure delayed reply: Delayed reply of meter data can be used to simulate poor carrier environment and reply timeout on site;

[0085] Configure module ID: create a module replacement action by modifying the module ID;

[0086] Configure phase information: Create abnormal phase sequence action by modifying the phase information.
