Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HVAC systems face challenges in efficiently configuring and managing wireless sensors, leading to difficulties in optimal environmental control within buildings.
Innovation Solution
The implementation of a building controller that enrolls and configures wireless devices, such as temperature and humidity sensors, through a user interface, allowing for the storage of device identifiers and display of screens to solicit information, enabling effective communication and control of HVAC components via wireless communication links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless sensors are used in HVAC systems, then system flexibility and ease of installation are improved, but device complexity and configuration difficulty increase
Solution Approach 1:
The system performs self-configuration through automatic enrollment where the building controller automatically discovers, enrolls, and configures wireless sensors without requiring manual intervention. The controller solicits identifiers automatically and stores them in memory, enabling the system to configure itself autonomously.
Solution Approach 2:
The building controller prepares configuration data structures and memory allocations in advance before wireless sensors are actually installed. The system pre-establishes enrollment protocols and identifier storage mechanisms, so that when sensors are added, the configuration process is already prepared and can proceed automatically.
2Measurement precision
If manual configuration of wireless devices is implemented, then device identification accuracy is improved, but time consumption and operational complexity increase
Solution Approach 1:
Wireless sensors automatically transmit their identifiers to the building controller during the enrollment process. The controller receives and stores these identifiers without requiring manual data entry, thereby maintaining accurate device identification while eliminating the time consumption associated with manual configuration.
3Adaptability or versatility
If multiple wireless devices are enrolled, then system monitoring capability is improved, but system complexity and management difficulty increase
Solution Approach 1:
The building controller implements a universal enrollment and management interface that handles all types of wireless sensors (temperature, humidity, occupancy) through the same process. The controller stores identifiers for multiple devices in a standardized memory structure and manages them through unified configuration screens, allowing the system to scale to multiple devices without proportionally increasing management complexity.

AI summary
An HVAC controller for controlling an HVAC system may be configured to enroll one or more wireless devices, and once one or more wireless devices are enrolled, to prompt the user to enter an identifier, a location, a device type and/or a function for one or more of the enrolled wireless devices. The HVAC controller may use the identifier, location and/or device type to identify each of the enrolled devices. This may facilitate a user in selecting various sensors to participate in sensor averaging, identifying where certain sensor data is originating, identifying devices having a low battery condition, as well as performing other tasks as desired.
