Automatic test and collection device and method of smart meter

The invention discloses an automatic test and collection device and an automatic test and collection method of a smart meter, belonging to the field of the smart meter. The device comprises an environmental test chamber, a data collection card and a control computer. The test method comprises the steps as follows: the control computer sets test items of the smart meter, and transmits test parameters to the environmental test chamber; the environmental test chamber finishes testing of the smart meter according to received signals of different test items, and the control computer controls the data collection card to collect the test data of the smart meter by setting the information to be collected. The collection method comprises the steps as follows: the smart meter of executing the test items uploads a voltage signal of the test data of an internal element to the data collection card; the data collection card uploads the voltage signal of the test data to the control computer after processing, and the control computer transmits the received test data to a data storage module to store. The device and the method disclosed by the invention are mainly applied to reliability tests such as an acceleration test, a strenuous test and the like of the smart meter, so that the blank of test equipment in the field is compensated.
