Pole-Mounted Distribution Box Data Access Without Climbing

The patent applies the dynamics principle by making the front panel movable through an electric telescopic rod mechanism. The front panel can dynamically change its position between extended (accessible) and retracted (protected) states, allowing the system to adapt between security and accessibility requirements. The control mechanism enables the front panel to move outward for data access and then retract for security, resolving the contradiction between these two static requirements.

The patent applies the self-service principle by enabling remote data access through the communication module. The power distribution box can automatically transmit its data (electrical equipment status, environmental parameters, etc.) to remote terminals without requiring maintenance personnel to physically access it. The system serves itself by making data available through network connections, eliminating the need for climbing and manual data collection, thus saving time and improving safety.

The patent applies the intermediary principle by introducing a control mechanism and communication module as mediators between maintenance personnel and the power distribution box. Instead of direct physical access, the control mechanism (with face recognition and card slot) and communication module enable indirect access through automated authentication and remote data transmission. This intermediary layer eliminates the safety risk of climbing while maintaining management efficiency through automated control and monitoring.
