if the spot check before the supply is a test after the bid in the national net, the electromagnetic compatibility test in the pattern test and the special test does not need to be used for the case library project test of all projects, because the electromagnetic compatibility test has destructiveness on the products, after the pattern test and the special test before the supply, the bid maker designs the products to have the normal working requirement in the electromagnetic environment, and then the subsequent test is to waste a great deal of manpower and material resources; secondly, the centralized bid-recruitment and goods-supply amount is large, the on-site installation time is short, the task is heavy, and the task of the spot inspection department is heavy. Based on the method, the functions, the performances and the insulation are tested for the spot check detection before the supply, so that the test flow is faster, and the centralized test of the supplied products can be more comprehensively carried out; the test cases of the main performance test and the environmental impact test of the three-remote DTU, the FTU, the two-remote DTU and the TTU of the network access special detection are simplified, and the specific steps are as follows:

The low temperature test the high temperature test selects performance test cases of different state input quantity, remote control, direct current input analog quantity, alternating current input analog quantity and resolution in the event recording station, and the tests are taken from the main performance test. Then in the primary performance test project, these test cases may be culled.
The wet heat test and the insulation resistance test are tested simultaneously, so that test cases are simplified.
After simplifying the test cases according to the distribution automation detection procedure and the historical detection cases, the method can comprise the following steps:
and the test cases with the same test case comprising the most detection purposes and the least detection adverse effects are used as targets, and the simplified test cases are optimally designed according to the detection conditions and the detection purposes of the historical detection cases. After simplifying the test cases, the method may include: the test case is optimally designed according to the detection effect so as to comprise more detection purposes, so that the test efficiency is improved, and meanwhile, the adverse effect of detection is reduced;
storing all simplified test cases;
the simplified test cases are associated with corresponding terminal types and terminal detection types, namely, different detection types have the functions of functional test, precision test, remote signaling anti-shake, remote control and the like, and different detection types in the case library can be the same corresponding case.

The energy supply detection content is shown in the following table:
Figure BDA0001602267350000071
Figure BDA0001602267350000081
(5) Electrical performance test
And (3) performing performance index test at normal ambient temperature, wherein un=220v, in=5a, and the test data voltage and current errors are less than 0.5%, and the active power and the reactive power are less than 1%.
(6) Power supply impact test

a plurality of detection terminals belonging to the same class can simultaneously execute detection on the premise of not affecting the detection efficiency and the detection precision;
for example: who tests the function, precision, insulation, etc. before; the pattern test is a test performed to verify whether the product meets all requirements of the technical specifications. It is an essential link in new product identification. Only through the model test, the product can be formally put into production, however, for product certification, the certification of the redesigned new product is generally not performed.

The configuration method should place destructive experiments such as surge in electromagnetic compatibility at the end of the experiment, ensure the smooth performance of the experiment and improve the test efficiency.
The network access professional detection is a special test for obtaining network access qualification for manufacturers, and the test items do not need to be subjected to comprehensive type test item test. The special detection test items are all tested according to the technical conditions of centralized bidding of the national network company, and the test structure is used for guiding the distribution terminal shipping standard of centralized bidding of the national network. For IP protection grade, 72 hours stable operation, damp heat and other time consuming problems which are related to the attention of each manufacturer on a flow production line and the tested items of pattern tests can not be tested, the efficiency is improved, and the production quality is improved.
In the special detection process, the performance can be tested before the function is tested by the configuration method of the use case library, whether the precision calibration of a manufacturer is accurate in factory test or not is monitored, if the performance error is not, the method can directly process according to disqualification in the subsequent function test.
Electromagnetic compatibility can be placed in the final test of special detection on the configuration of the use case library.
Before and after the goods are delivered, the product quality of each terminal of a manufacturer is detected mainly aiming at centralized bidding projects of power supply companies in various provinces of the national network. The detection of the two parts is relatively close to the field guidance, so that strict and detailed tests on functions, performance accuracy, electromagnetic compatibility, insulation and the like of the field terminal are required.
The sequence of electromagnetic compatibility and function and performance tests on the configuration method can be carried out by referring to the type test and network entry special detection.
Before detection, importing all the information of the inspection terminal; in the detection, the system can record the detection time, detection duration, detection state and the like of each test item of various terminals, and can automatically count the average detection duration of each item of different detection types and different types of terminals.
The test system flexibly arranges the test item sequence of each inspection terminal, and comprises the following specific steps:
A. b, C, D, E, F is six inspection terminals arranged according to the inspection time, and it is assumed that three modules K1, K2, K3 and A, B of the test system are detected on K1, C, D is detected on K2, K3 is idle, and E, F is the completion of the detection of the test items on K3;
