RV Hookup Pedestal Control for Reservation-Based Utility Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recreational vehicle (RV) parking facilities lack integrated automated systems that allow for remote reservation and control of utility services, such as electrical power, water, and sewage, necessitating on-site staff for managing and preventing unauthorized access.
Innovation Solution
An automated system utilizing multiservice hookup pedestals with programmable logic controllers (PLCs), smart switches, and smart valves, integrated with reservation software, enables remote activation and deactivation of utility services based on reservation information and sensor data, eliminating the need for on-site staff and ensuring secure access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If on-site staff are used to manage and prevent unauthorized access to RV parking facilities, then security and access control are improved, but labor costs and operational complexity increase
Solution Approach 1:
The system enables automated self-service operation where the RV parking facility manages itself through integrated sensors, PLCs, and reservation systems. The hookup pedestals automatically detect vehicle presence, verify reservations, and activate utility services without human intervention, eliminating the need for on-site staff while maintaining security and access control
Solution Approach 2:
Manual mechanical systems of staff monitoring and accessing parking sites are replaced with an automated electronic control system. PLCs receive sensor data, process reservation information, and automatically control utility service activation through hookup pedestals, substituting human operational complexity with automated electronic control
2Productivity
If automated reservation systems are implemented, then operational efficiency is improved, but integration with utility service activation becomes complex
Solution Approach 1:
The reservation system and utility service activation system are merged into a single integrated automated control system. The PLC receives both reservation data and sensor information, then automatically coordinates parking site assignment and utility service activation, eliminating the need for separate manual coordination processes
Solution Approach 2:
The hookup pedestal serves multiple functions: it detects vehicle presence through sensors, communicates with the PLC for reservation verification, activates utility services, and provides power to the parking site. This multi-functional design simplifies system integration by consolidating multiple operations into a single universal interface
3Extent of automation
If self-service hookup pedestals are used, then labor requirements are reduced, but integration with reservation systems is lacking
Solution Approach 1:
The system implements feedback loops where sensors continuously monitor vehicle presence and status, communicate this information to the PLC, which then verifies reservation data and adjusts utility service activation accordingly. This feedback mechanism enables the self-service pedestal to adapt its operation based on real-time conditions and reservation status
Solution Approach 2:
The system performs preliminary actions by pre-assigning parking sites through the reservation system before the guest arrives. The PLC stores this reservation information and automatically activates utility services when the vehicle is detected, eliminating the need for on-site manual activation and enabling seamless integration between reservation and service delivery

AI summary
The automated system provides automated and remote monitoring, control, communication, and management of recreational vehicle parking facilities, providing guests access to electric, water and sewer services via onsite hookup pedestals. Following the guest's reservation, payment and arrival at the correct parking site which is verified by sensors monitoring the sites, the system activates one or more hookup pedestals via smart switches and smart valves on separate power circuits from the sensors. A PLC operates with a smart switch to close the switch and deliver electrical power and also operates with the smart valve's actuator to an open flow state and a, and the electrical power activates a manual switch that disengages a cover latch which provides access to the dump station inlet. When a reservation window ends or the site is vacated, the system deactivates the hookup pedestals to end access to the utility services while the sensors remain active.
