The data acquisition system (DAS) developed at Structural Integrity Associates (SIA), known as Fire Engine system is a robust and portable data acquisition solution developed for measuring accelerometers and other instrumentation in challenging field environments. Designed to endure extreme conditions, including severe vibration and background noise, high impact, harsh weather, and temperature extremes, the system is utilized in industrial settings requiring reliability and compactness. The current CAPSTONE project focuses on upgrading the Fire Engine to improve functionality, durability, and adaptability for diverse applications. Key upgrades include: 1. Battery Backup Integration: Ensuring uninterrupted operation during temporary power outages, the project involves identifying a compact, off-the-shelf solution that can provide at least 10 minutes of backup power. The chosen system must fit within the existing cabinet and withstand field transport conditions. a. The potential electrical Noise should be anticipated and filtered, and the quality of data should not be decreased. b. Battery Recharging, should not change temperature inside the DAS 2. Integrated 120V Power Output: Adding a dedicated 120V output allows the Fire Engine to power auxiliary devices, such as laptops, eliminating the need for external power strips and streamlining field setups. 3. Connection Panels Options i. Strain Gauge Recording Panel: Designing a modular panel to facilitate strain gauge data acquisition supports up to 16 channels with configurable circuit options (¼, ½, and full bridge configurations). This panel will include features such as completion resistors and grounding dip switches, optimizing it for flexibility in various field applications. ii. Improved BNC Panel Connectivity: Addressing noise issues caused by microdot connectors, the project seeks to enhance the reliability of connections between the NI-9231 module and the BNC panel. Proposed solutions include circuit board-mounted connectors and a robust external interface to reduce data inconsistencies. iii. Laser Distance Sensor Panel: Developing a modular and swappable panel for integrating laser distance sensors includes provisions for power supply and streamlined connections to the DAS system. This addition enhances the system’s versatility for distance measurement applications. This comprehensive upgrade project emphasizes innovative engineering design, seamless integration of components, and rigorous testing to ensure field readiness. The enhanced Fire Engine will serve as a versatile and reliable tool for diverse data acquisition needs.
