A fee-control card-meter interaction data and sequential obtaining system and an obtaining method are provided; the system comprises a file server, a main control computer, an information obtaining tool and an information processing device connected in sequence; when the fee-control card-meter are under an interaction online state, the information obtaining tool can sense card-meter interaction signals and transmit same to the information processing device; when the fee-control card-meter is under a non-interaction offline state, the information processing device can form ammeter or power purchasing card simulation signals, and interacts with the card-meter through the information obtaining tool, thus obtaining card-meter interaction signals. The main control computer reads the interactiondata and sequential signals processed by the information processing device, and can transmit the data to the file server for storage. The system and method can effectively improve the fee-control card-meter interaction data and sequential obtaining efficiency, accuracy and integrity, thus providing technical supports for developing the fee-control ammeter and power purchasing card interaction sequential and message accuracy detections.
