DMC and our partners designed, manufactured, and programmed several fixed stations and several mobile test stations for use in our client\u2019s controlled burn laboratory. The client has strict reliability and performance requirements for the data acquisition system due to the costly nature of setting up and executing the tests (in both time and expense).<\/p>\n\n\n\n
DMC used UEI\u2019s PowerDNA Cube platform to ensure maximum uptime and reliability. The UEI hardware platform is mechanically and electrically ruggedized for operation in harsh conditions and can be configured with a variety of different I\/O channels.<\/p>\n\n\n\n
DMC developed a C++ application (using the Poco framework<\/a> and ZeroMQ<\/a>) that runs directly on the Cube\u2019s operating system. The Cube is configured to run a standard Linux kernel with a real-time API, so all development can be done using the familiar GNU toolchain. This application acquires and processes data during a test, and then sends that data to a network location for analysis and long-term storage.<\/p>\n\n\n\n For accurate thermocouple temperature measurements, DMC implemented cold junction compensation (CJC) calculations in the UEI Cube software per the client\u2019s standards.<\/p>\n\n\n\n The data acquisition stations were synchronized using the Precision Time Protocol (PTP) to ensure that data from all stations could be time-aligned and correlated for post-processing.<\/p>\n\n\n\n Acquired data is streamed in real-time to a centralized server using ZeroMQ. There, data streams are processed based on the test\u2019s custom configuration, offering dozens of preset or customizable formulas (e.g., min, max, integral, derivative, mass flow calculations, heat release rate) selected to meet the client\u2019s requirements for that burn test.<\/p>\n\n\n\n To ensure that no valuable test data is lost if the network location is unavailable, data is cached locally in a Sqlite database until it can be uploaded to permanent storage in a SQL Server Columnstore.<\/p>\n\n\n\n DMC developed an ASP.NET Core web backend and a React frontend for operators, engineers, and managers to interact with the test station configurations and historical data.<\/p><\/p>\n\n\n\n Some notable features of this application include:<\/p><\/p>\n\n\n\n DMC\u2019s use of Commercial-Off-The-Shelf (COTS) hardware paired with several layers of custom software integration provided our client with a robust, flexible, and scalable system to meet their testing needs. DMC continues to work with this client to add new features to the system.<\/p>\n\n\n\n Learn more about DMC’s Test and Measurement Automation<\/a> expertise and contact us<\/a> for your next project.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":" DMC and our partners designed, manufactured, and programmed several fixed stations and several mobile test stations for use in our client\u2019s controlled burn laboratory.
