The V1 Beidou short message handheld terminal developed by Dingjian (Shenzhen) Communication Technology Co., Ltd. can provide real-time positioning and SMS communication functions through Beidou satellites in an environment without a public network. When electric power workers conduct field inspections, they often encounter environments without a public network. At this time, the short message function of V1 is used to send inspection data and information to the background through satellites. The command center monitors the power grid lines in real time through background data to ensure the safety of the power grid.
