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.

Description

technical field [0001] The invention relates to a remote verification system of a digital multimeter based on a cloud service mode. technical background [0002] The verification of traditional digital multimeters needs to be transported to the verification laboratory, and the manual verification mode is adopted, which has defects such as low verification efficiency, large errors, and waste of manpower and material resources. The invention is a remote verification system of a digital multimeter based on a cloud service mode, and its verification is greatly improved in terms of verification efficiency and accuracy.
