摘　　要：传统的高压直流分压器校准方法是将仪器送到上级检定机构,或者检定人员到现场进行检定,时间成本巨大并且被检器在运输过程中有损伤的风险,而远程校准可以完美解决这些问题。基于QT开发控制端、现场端软件,通过套接字实现控制端、现场端软件与云平台的通信,再利用云平台转发消息实现控制端与现场端的通信。使用萤石云实现现场画面实时监控及语音通话,以此保证校准的合法性。验证结果表明,基于云平台的高压直流分压器远程校准系统可以实现远程校准的目的。The article aims to realize the remote measurement calibration of the high voltage DC voltage divider.The traditional calibration method is to send the instrument to the higher-level verification organization or the verification personnel to the site for verification,which is time-consuming and has the risk of damage during transportation,while remote calibration can perfectly solve these problems.Based on QT,we developed the console and fieldside software,realized the communication between the software of both sides and the cloud platform through sockets,and then used the cloud platform to forward messages to realize the communication between the two sides.The Ezviz Cloud is applied to realize real-time monitoring of on-site images and voice calls to ensure the legality of calibration.The verification results show that the cloud-based remote calibration system of the high-voltage DC voltage divider can achieve the purpose of remote calibration.
