Testing method for verifying reliability of electricity utilization information collecting device

Abstract

The invention provides a testing method for verifying the reliability of an electricity utilization information collecting device. The testing method includes the following steps: building an electricity utilization information collecting device reliability model, determining a failure mode, a failure criteria and a failure statistic principle, carrying out a temperature-humidity-constant stress accelerated life test on the electricity utilization information collecting device, carrying out failure statistic, analyzing test data obtained through the accelerated life test, and obtaining the accumulated failure probability and the reliability. According to the testing method for verifying the reliability of the electricity utilization information collecting device, the temperature-humidity-constant stress accelerated life test on the electricity utilization information collecting device is guided to be carried out by building the electricity utilization information collecting device reliability model, and estimated values of reliability characteristic variables under the normal use condition are derived through failure data under the accelerated condition to verify whether the reliability of the electricity utilization information collecting device meets requirements or not.

Description

technical field [0001] The invention relates to a test method, in particular to a test method for reliability verification of electricity information collection equipment. Background technique [0002] In the construction of electricity consumption information collection system, due to the large scale of the system, many types of collection equipment, various operating environments, long continuous operation time, complex communication media and communication protocols, the reliability of collection equipment is becoming more and more prominent, which restricts the collection System promotion and application. [0003] In order to achieve the goal of full coverage and full collection of the electricity information collection system, it is required that the collection equipment can operate reliably for a long time in various operating environments (including electromagnetic environment, climate environment, etc.). At the same time, the functions realized by the power consumpt...
