This paper proposes a distributed remote calibration prototype based on a cloud\u2013edge\u2013end architecture by integrating intelligent sensing, Internet of Things (IoT) communication, and edge computing technologies. The prototype employs a high-precision frequency-to-voltage conversion module leveraging satellite signals to address traceability and value transmission challenges in remote calibration, thereby ensuring reliability and stability throughout the process. Additionally, an environmental monitoring module tracks parameters such as temperature, humidity, and electromagnetic interference. Combined with video surveillance and optical character recognition (OCR), this enables intelligent, end-to-end recording and automated data extraction during calibration. Furthermore, a cloud-edge task scheduling algorithm is implemented to offload computational tasks to edge nodes, maximizing resource utilization within the cloud\u2013edge collaborative system and enhancing service quality. The proposed prototype extends existing cloud\u2013edge collaboration frameworks by incorporating calibration instruments and sensing devices into the network, thereby improving the intelligence and accuracy of remote calibration across multiple layers. Furthermore, this approach facilitates synchronized communication and calibration operations across symmetrically deployed remote facilities and reference devices, providing solid technical support to ensure that measurement equipment meets the required precision and performance criteria.<\/jats:p>","DOI":"10.3390\/sym17091434","type":"journal-article","created":{"date-parts":[[2025,9,3]],"date-time":"2025-09-03T08:04:15Z","timestamp":1756886655000},"page":"1434","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Design and Implementation of a Novel Intelligent Remote Calibration System Based on Edge Intelligence"],"prefix":"10.3390","volume":"17","author":[{"given":"Quan","family":"Wang","sequence":"first","affiliation":[{"name":"China Electric Power Research Institute, Wuhan 430074, China"},{"name":"National Center for High Voltage Measurement, Wuhan 430074, China"},{"name":"Key Laboratory of Measurement and Test of High Voltage and Heavy Current, State Administration for Market Regulation, Wuhan 430074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiliang","family":"Fu","sequence":"additional","affiliation":[{"name":"China Electric Power Research Institute, Wuhan 430074, China"},{"name":"National Center for High Voltage Measurement, Wuhan 430074, China"},{"name":"Key Laboratory of Measurement and Test of High Voltage and Heavy Current, State Administration for Market Regulation, Wuhan 430074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xia","family":"Han","sequence":"additional","affiliation":[{"name":"State Grid Shanxi Marketing Service Center, No. 10 Wuluo Street, Xiaodian District, Taiyuan 030002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaodong","family":"Yin","sequence":"additional","affiliation":[{"name":"China Electric Power Research Institute, Wuhan 430074, China"},{"name":"National Center for High Voltage Measurement, Wuhan 430074, China"},{"name":"Key Laboratory of Measurement and Test of High Voltage and Heavy Current, State Administration for Market Regulation, Wuhan 430074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jun","family":"Zhang","sequence":"additional","affiliation":[{"name":"China Electric Power Research Institute, Wuhan 430074, China"},{"name":"National Center for High Voltage Measurement, Wuhan 430074, China"},{"name":"Key Laboratory of Measurement and Test of High Voltage and Heavy Current, State Administration for Market Regulation, Wuhan 430074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xin","family":"Qi","sequence":"additional","affiliation":[{"name":"China Electric Power Research Institute, Wuhan 430074, China"},{"name":"National Center for High Voltage Measurement, Wuhan 430074, China"},{"name":"Key Laboratory of Measurement and Test of High Voltage and Heavy Current, State Administration for Market Regulation, Wuhan 430074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xuerui","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Grid Shanxi Marketing Service Center, No. 10 Wuluo Street, Xiaodian District, Taiyuan 030002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"012032","DOI":"10.1088\/1742-6596\/2815\/1\/012032","article-title":"Research on calibration method for measurement error of multiple rate carrier energy meter","volume":"2815","author":"Zhang","year":"2024","journal-title":"J.
