Abstract: As an essential carrier for communication in acquisition devices, communication cards directly affect the timeliness and accuracy of power data collection. Traditional communication cards rely on manual management, and there is no detection device that can comprehensively test the operation of various functions of the communication cards. Based on this, this paper develops a detection and management device for communication cards in acquisition terminals. The detection device is designed with 4 GPRS communication modules in its hardware structure,capable of inserting 16 standard communication card sockets to achieve synchronous testing of multiple modules. At the same time, management software is developed to achieve the service tracking in entire process of communication cards. Test results show that the communication cards detection and management device developed in this paper can effectively reduce the time for testing cards, improve work efficiency, reduce the risk of communication card information security, and enhance the management level of the entire life cycle of communication cards.
