Abstract
The invention relates to a cloud service mode-based remote verification system of a digital multimeter. A remote server end gives out and transports transmission standards to a client end. A standard device is connected with a to-be-verified meter via a multi-way switch, thereby facilitating channel switching of all detection items. A mobile terminal supporting NFC is used for reading to-be-verified meter information and verification records of NFC electronic tags on the to-be-verified meter. A verification software front panel sends the to-be-verified meter information and the verification records to the remote server end via network, thereby achieving real-time interaction of data. After the verification is finished, a cloud database for storing the verification records and the verification data is established on a cloud end via a cloud server, thereby facilitating record searching and data sharing. The mobile terminal is used for reading in the verification records of the NFC electronic tags of the to-be-verified meter so as to easily verify reading of information of the to-be-verified meter next time. Compared with a manual verification mode of a traditional digital multimeter, verification efficiency is greatly increased and errors caused by manual factors are reduced.
