This paper introduces a design of the whole event collection test system for electricity information acquisition system. The system reproduces the scene noise, simulates the field wiring mode and attenuates the analog signal. The whole test system simulation field environmental impact, automatically generate events and sampling results, recording equipment acquisition process, the better effects of different sampling scheme of the whole event validation. Testing system has been applied to actual testing work of this paper, the research results of relevant power carrier communication product evaluation, selection, and is of great significance in promoting the whole event gathering effect promotion.
