Test method based on final circular test (FCT) multi-station test device

Abstract

The invention discloses a test method based on a final circular test (FCT) multi-station test device. The test method based on the FCT multi-station test device comprises the following steps: establishing a supply voltage database, writing in an address for a printed circuit board assembly (PCBA) of an electric energy meter, writing in a relay return circuit test program for the PCBA of the electric energy meter, establishing a test database, establishing an impulse test database, establishing a clock test database, fixing the PCBA on a single-station test device, supplying power for the PCBA of the electric energy meter, detecting supply voltage, detecting 485 port, detecting a relay return circuit of the PCBA, detecting the impulse of the electric energy meter, detecting a clock of the electric energy meter, lowering the voltage, detecting battery a current of the PCBA of the electric energy meter, and fetching out the PCBA of the electric energy meter from the single-station test device. The test method based on the final circular test (FCT) multi-station test device has the advantages of being time-saving, labor-saving, high in test efficiency and high in precision of test results.

Description

technical field [0001] The invention relates to a testing method based on an FCT multi-station testing device. Background technique [0002] At present, the normal test of the electric energy meter PCBA board is carried out by a multimeter. During the test, each data parameter of an electric energy meter PCBA board is tested one by one by a multimeter, and then compared with the normal data parameters, so as to realize the normal test of the electric energy meter PCBA board. The following problems exist in the testing method of this multimeter: 1, because can only test a watt-hour meter PCBA board at a time, and need to test parameter by parameter during testing, so this method is not only time-consuming and laborious to test, and test efficiency is low. 2. Since the above-mentioned test devices are all simple devices, the test results are easily affected by other conditions, and the accuracy of the test is low. 3. Since employees sometimes come into contact with the PCBA ...

AI Technical Summary

Problems solved by technology

There are following problems in the testing method of this multimeter: 1, because can only test a watt-hour meter PCBA board at a time, and need to test parameter by parameter during testing, so this method is not only time-consuming and laborious to test, and test efficiency is low

2. Since the above test devices are simple equipment, the test results are easily affected by other conditions, and the accuracy of the test is low

3. Since employees sometimes come into contact with the PCBA board of the electric energy meter during the test process, it is very easy to get an electric shock and cause a safety accident
