Building management system with automatic remote server query for hands free commissioning and configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current HVAC control systems require significant resources and are prone to human error in manual configuration, often relying on default parameters that may not accurately represent device operating characteristics, leading to system errors difficult to diagnose and remedy.
Innovation Solution
A building management system with a master controller that queries slave devices for identification codes, connects to a remote server database, and configures devices based on received configuration information, eliminating the need for manual entry and default values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual configuration methods are used to set device parameters in HVAC systems, then flexibility and adaptability are maintained, but significant resources and time are required and human error is prone
Solution Approach 1:
Device configuration data is prepared and stored in a database before the devices are installed or connected to the system. When a device is added to the HVAC system, the master controller automatically queries the database using the device's identification code and retrieves the pre-configured parameters, eliminating the need for manual configuration during installation.
Solution Approach 2:
The system enables automatic self-configuration of HVAC devices through the master controller querying slave devices for their identification codes, automatically retrieving corresponding configuration data from the database, and applying the settings without human intervention. This self-service mechanism reduces both time and error rates.
2Productivity
If default parameters are used for device configuration, then resource requirements are reduced, but the parameters may not accurately represent the operating characteristics of the controlled devices
Solution Approach 1:
Instead of using uniform default parameters for all devices, the system stores and applies device-specific configuration parameters tailored to each individual device's model, manufacturer, and operational characteristics. The master controller retrieves customized parameter sets from the database based on each device's unique identification code, ensuring locally optimized settings.
3Adaptability or versatility
If manual configuration is performed, then customization to device specifics is possible, but the process is time-consuming and error-prone
Solution Approach 1:
The system creates and stores digital copies of device configuration data in a centralized database during the manufacturing or commissioning phase. These configuration copies include all necessary parameters for specific device models and are automatically retrieved by the master controller when devices are added to the system, eliminating repetitive manual configuration work.

AI summary
A building management system includes a communications bus, slave devices connected to the communications bus, a remote server that includes a slave device configuration database, and a master controller connected to the communications bus. The master controller is configured to query the slave devices for device identification codes, receive device identification codes from the slave devices, and connect to the remote server. The master controller is further configured to transmit device identification codes to the slave device configuration database, receive slave device configuration information from the slave device configuration database, and control the slave devices based on the slave device configuration information.
