Using LabVIEW and CompactRIO, we created the Biorep perfusion system quickly and cost-effectively

Biorep Technologies is a company that designs the equipment needed to isolate specific cells (islets) in the pancreas. This complex process involves more than 20 different pieces of equipment, 5 of which require a high degree of automation. The automation of these machines employs different platforms and programming languages. As the company grows, new problems arise, with multiple learning curves, lengthy documentation, and different communication protocols between tier-one platforms, making it inefficient.

After getting a good understanding of NI products, we started using LabVIEW for all of our robotics, which required only a common platform, a learning curve, and a much simpler supply chain. Its sophisticated debugging tools and remote troubleshooting capabilities have saved us over $10,000 in time and travel costs.

Using LabVIEW and CompactRIO, our software engineers created a complex automated instrument in just 3 months. The instrument includes multi-axis motion control (stepper motors), precise chamber temperature control, and sophisticated fluid handling (electric valve matrix control). We developed the software architecture using LabVIEW Real-Time and the LabVIEW FPGA Module. Real-world motion simulation with the LabVIEW NI SoftMotion Module allows us to predict and optimize designs and evaluate different design concepts before making physical prototypes. Using LabVIEW and CompactRIO, our development time was reduced from 12 months to 3 months and the need to develop custom control software and drivers was avoided.

We initially used the Biorep perfusion system as a tool to test the ability of in vitro islets. Its capabilities have since been extended to measure the secretions of different cells differentiated from primitive pancreatic stem cells, and have become an integral part of pharmaceutical companies’ search for new drugs.

Monitoring Atmospheric Ozone Conditions on a Global Hawk UAV Using CompactRIO

Challenge: Develop an ozone monitoring instrument that can work on NASA’s Global Hawk Unmanned Aeronautical Vehicle. It is required to be able to communicate with the ground, perform local streaming of data, and be able to synchronize via the Network Clock Protocol (NTP).

Solution: Use CompactRIO to issue commands, control and communicate with the Unmanned Ozone Monitoring System (UAS O3).

The CompactRIO-based ozone monitoring device was successfully assembled on a NASA Global Hawk drone at NASA Dryden Flight Research Center

The Earth System Research Laboratory in Boulder, Colorado, part of the National Oceanic and Atmospheric Administration, has been studying the processes that govern chemical reactions in the Earth’s atmosphere and long-term climate change to predict atmospheric changes. behavioral patterns.

The ozone monitoring instrument we’ve been using is 22 years old and weighs 57 pounds. We need to upgrade the instrument, reduce weight, and add networking capabilities.

Our new UAS O3 ozone tester is an absorption dual beam UV intensity meter. One beam is used to measure ozone conditions in the collected atmospheric sample, and the other beam is passed through the same atmospheric sample through an ozone filter. The instrument weighs only 37 pounds, uses 28V DC power supply, and has an adjustable sampling rate from 0.5 to 10 Hz.

The Compact RIO controller meets the high processing speed, low power consumption, high mechanical strength, and size requirements of a test instrument, enabling the processing of unpressurized atmospheric data from unmanned aircraft (such as NASA’s Global Hawk UAV) at altitudes of 64,000 feet.

Controlling Echogen Energy Systems’ Waste Heat Engines

Challenge: Develop a real-time application to control and monitor Echogen Energy Systems’ waste heat engines, while creating a Windows-based application to enable remote and local monitoring of the overall system.

Solution: Develop a LabVIEW application on the CompactRIO platform to control the waste heat engine, using multi-PID closed-loop control to achieve system determinism requirements.

Echogen Energy Systems’ waste heat engines are geared towards industrial waste heat recovery and can capture heat from a variety of energy sources. Based on its basic equipment, we developed a controller and plant health monitoring system for a waste heat engine with a nominal net rating of 250kW.

To achieve strict I/O synchronization metrics, we chose the CompactRIO real-time controller. This heat engine is primarily designed for testing, and the system requirements include the acquisition of more than 75 sensor signals and the control of more than 40 instruments via Modbus, analog, and digital signals. In addition, on the basis of the read system variables (eg: system pressure, fluid temperature, turbine load), we employ a multi-PID control algorithm to control this system.

In the system architecture, the system is run remotely, but we designed a local human-machine interface (HMI) to realize control and monitoring. At the same time, we use Ethernet connection between Windows computer and real-time controller running LabVIEW application to realize network-published shared variables, so as to complete process data interaction and message-based information communication.

At the same time, the CompactRIO controller running the LabVIEW real-time application has a multi-core central processing unit. The NI Distributed System Manager has given us a lot of help in the development process, allowing us to comprehensively monitor the information of each system in the network, manage the published data, and access the network publishing and sharing without developing applications by ourselves. Variables and I/O Variables. We can even remotely debug and calibrate process parameters by adjusting the values ​​of network-published shared variables without any HMI. Using a variety of toolkits and development Modules from NI allows us to quickly adapt the system to meet the further needs of our customers.
