Description

Technical Field

[0001] The present invention relates to the technical field of electric energy meter testing, and in particular to an automatic testing method and device for an electric energy meter. Background Art

[0002] Traditional energy meter testing methods mainly rely on manual operation of test equipment and energy meters to meet the test conditions or scenarios and working conditions in the test. For example, the tester needs to manually press the button of the energy meter, observe the flashing status of the LED indicator, perform short-circuit operations on the test pins or contacts, and open / close the meter cover / module cover / terminal cover and other operations. This manual operation method has the following problems: it consumes a lot of human resources and increases the test cost: since the energy meter function test involves multiple operation steps, a large number of testers are required, resulting in high labor costs; it is easily affected by human factors, resulting in unstable test results and low accuracy: there are certain errors and randomness in manual operation, which can easily lead to deviations in test results and affect product quality assurance; the test efficiency is low and it is difficult to meet the needs of rapid product iteration: the manual operation test is slow, which is difficult to meet the needs of rapid product development and iteration, and delays the time to market.

[0003] For the existing test contents that require operation, such as pressing the button or keyboard of the electric energy meter, opening / closing the cover or switch of the electric energy meter, the manual operation can be replaced by the introduction of equipment such as manipulators, but the following problems still exist: High cost: A set of robot-type equipment that supports the completion of the corresponding manual operation includes software systems and hardware equipment, which is expensive, costing hundreds of thousands. If you want to meet the test of batch electric energy meters, you need to introduce multiple sets of equipment, the development cost is soaring, and the cost performance is low; The equipment is bulky and requires a large amount of space: Compared with an electric energy meter itself, the robot equipment occupies a large space, and the laboratory needs to provide more space to meet the operation requirements during the test; Poor product adaptability: For the fast-iterating electric energy meter products, their physical structure will change with the continuous development of the product, and the physical structure of the products for different customers and markets will also be greatly different due to the differences in demand. It is difficult to achieve compatibility with different products and different versions.

The analog circuit may include circuit elements and circuit connection diagrams. The analog signal board simulates the signals generated by various operation behaviors on the electric energy meter through the analog circuit, such as button pressing, LED indicator flashing, opening and closing of the meter cover, etc. The interface and signal specifications of different types of electric energy meters need to be considered in the design process to ensure the accuracy and reliability of the analog signal. After starting the test, the corresponding test case is read in the test case library, and according to the instructions in the test case, the analog signal board is controlled to output the corresponding analog operation signal. The analog operation signal is used to simulate manual operation, and the test result corresponding to the electric energy meter to be tested is obtained according to the analog operation signal; by replacing manual operation with automation, manpower input can be reduced and testing costs can be reduced; the hardware circuit simulation operation behavior is more stable and accurate, avoiding the specific errors caused by manual operation, and improving the reliability of the test results; the introduction of automated testing can quickly execute multiple test cases at the same time, significantly improving test efficiency and shortening the test cycle; due to the implementation of automated testing and the replacement of manual input, for mature test scenarios and test cases, 24h uninterrupted stable operation can be achieved, and rapid iteration can be achieved in conjunction with the product agile development process.
