Testing method for verifying reliability of electricity utilization information collecting device

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.
