With the rapid development of urban distribution networks, especially in large civil buildings and residential areas, it is required to use indoor distribution rooms (stations) for power supply, which is conducive to meeting the electricity needs of urban residents. The power supply of distribution rooms (stations) is directly linked to an indispensable part of users' daily lives, and their reliable power supply capacity and quality are not only a direct reflection of the economic benefits of power enterprises, but also correspond to immeasurable social benefits. Unmanned distribution rooms (substations) are geographically dispersed, which is the main reason why operation and maintenance personnel cannot detect faults or hidden dangers in a timely manner, resulting in greater losses. Therefore, environmental monitoring in distribution rooms (substations) has become an urgent problem to be solved. Hidden dangers such as human destruction, illegal entry, excessive harmful gases, fire linkage, underground cable trench immersion, as well as greater losses caused by failure to detect faults or hidden dangers in a timely manner, require a "real-time online, centralized monitoring intelligent inspection and monitoring system". The establishment and application of this system can overcome the blindness of regular maintenance, reduce maintenance frequency, lower maintenance costs, and delay maintenance cycles, and truly achieve condition based maintenance for operation management departments, thereby improving equipment operation rate and unmanned distribution rooms. The operation provides a powerful technical support platform. The system described in this article is designed for this purpose and has extremely high application value. The intelligent environment monitoring and early warning system for unmanned distribution rooms (substations) is an important part of evaluating the environmental status of the site. It is necessary to provide technical support for risk analysis, fault diagnosis, and maintenance strategy decision-making.

The intelligent inspection and monitoring system for power distribution rooms (substations) utilizes modern computer technology, network technology, image technology, security monitoring, anti-theft alarm, and environmental comprehensive monitoring technology to launch a complete solution for unmanned intelligent power distribution room (substation) monitoring, warning, and linkage. It realizes the status monitoring of sulfur hexafluoride gas content, oxygen content, ozone content, temperature and humidity, access control, and video information in the environment of the unmanned intelligent power distribution room (substation). According to the pre-set start-up plan, it intelligently controls equipment such as air conditioning, video, heating, dehumidification, ventilation, and water pumps. At the same time, signals such as fire alarms and smoke can be introduced for intelligent linkage, and the transmission of status information is transmitted to the monitoring center through various communication methods. Staff can view the real-time situation in various unmanned intelligent distribution rooms (stations) in the monitoring center, reducing the intensity of inspection personnel, strengthening the security and fire monitoring of unmanned intelligent distribution rooms (stations), and improving the operation of unmanned intelligent distribution rooms (stations). This effectively improves the automation and modernization level of information management in unmanned intelligent distribution rooms (stations), and provides a complete solution to achieve ubiquitous power Internet of Things management.

The intelligent inspection and monitoring system for the distribution room (station) is constructed into a centralized management and distributed processing mode intelligent inspection and monitoring system consisting of intelligent environmental control terminals, environmental monitoring subsystems, linkage control subsystems, and security monitoring subsystems.
