Abstract: After grounding or other abnormalities that endanger the personal safety of on-site personnel occur in the current substation, insufficient attention is paid to on-site operators, who are unable to quickly evacuate due to the alarm information and are exposed to high-risk operating environments. Through research, our research group has independently designed and produced a comprehensive personal safety warning and management system for power production sites. It can send out sound and light alarms in the first time after abnormal situations occur, reminding on-site personnel to quickly evacuate the site, and optimizing on-site disposal methods. It can overcome the long-standing problems on site such as slow access to grounding information, inconvenient access to safety tools, and inadequate grounding disposal. It plays a significant role in ensuring the personal safety of on-site operators and improving grounding disposal efficiency.
