In order to effectively and reliably trace the quality of the smart watt-hour meter before supply, all samples for full performance test before supply need to be kept. In this paper, under the conditions of existing warehouses, the layout of smart energy meter warehouse is rationally designed to achieve the maximum storage capacity. Using the Internet of Things technology, we develop an intelligent gyration library that meets the requirements of the actual warehouse, and at the same time, we develop a set of intelligent warehouse management system. Through the binding of RFID tags and measuring instruments, the unique identity of measuring instruments in the warehouse is established, based on RFID group reading technology, the status of measuring instruments in the warehouse is automatically monitored, the warehouse is automatically counted, and the inspection cycle management of measuring instruments is realized. The application of the Internet of Things technology helps to solve the problem of sample management of measuring instruments and enriches the means of management of measuring instruments warehouses.
Electric energy measurement as a basic work, an accurate measurements play a vital role for the economic interests of both parties of power supply, the standardized management of the measurement laboratory at all levels is a direct factor that directly affects the fairness of measurement. Currently, the management of metering laboratories generally uses one-dimensional bar code as the recognition object, advances the testing process by manual management, most of the test data requires human input to generate reports. There are many problems and potential risks in this process: Data cannot be saved completely, cannot trace the status of inspection, the inspection process isn’t completely controllable and so on. For the provincial metrology center’s actual requirements of the whole process management for the performance test of the power measuring appliances, using of large-capacity RF tags as a process management information media, we developed a set of general measurement experiment management system, formulated a standardized full performance test process, improved the raw data recording mode of experimental process, developed a storehouse automatic inventory device, established a strict test sample transfer and storage system, ensured that all the raw data of the inspection can be traced back, achieved full life-cycle control of the sample, significantly improved the quality control level and the effectiveness of inspection work.
