Scalable ultrasound and volume flow sensor platform for optimising energy efficiency in industry

 

Scalable ultrasound and volume flow sensor platform was nominated for the XXV. Innovationspreis Thüringen 2022

On Nov. 30, 2022 in Weimar, the IMMS Institut für Mikroelektronik- und Mechatronik-Systeme gemeinnützige GmbH (IMMS GmbH) has been nominated in the category "Industry and Material" for the scalable ultrasonic and volume flow sensor platform "sUSe" on the XXV Innovationspreis Thüringen 2022. The platform is intended for the optimization of energy efficiency in industry. The system will be prepared for market launch with the development partner SONOTEC GmbH from spring 2023.

Platform helps save energy for compressed air in industry 
 

"Even before the energy crisis, industry was combating leaks in compressed air lines, as they cause the most energy losses and thus also unnecessary costs. In view of the current price development, it is even more important for companies to find such leaks, evaluate losses and initiate maintenance measures," explains Dr. Tino Hutschenreuther, subject area manager for system design at IMMS. 

Up to 10% of electrical energy is used in a wide variety of industries to generate compressed air alone, for example to drive machines and cylinders, transport materials or small parts, cool molded or cast parts, flush gas tanks or operate exhaust, ventilation and drying systems. On average, 30% of this compressed air is lost due to leakage.

In order to significantly reduce such losses, the IMMS has developed the sUSe electronics platform for an automatable solution for the sensors of the cooperation partners SONOTEC GmbH and Postberg+Co. GmbH. The sUSe system consisting of platform and sensors can be retrofitted in industrial compressed air systems to 

permanently monitor them, improve energy efficiency and save CO2 emissions.

For the first time worldwide, the system combines hybrid sensor technology and data fusion in one device which allows for a holistic and continuous monitoring 

Until now, leaks in compressed air systems have been measured, analyzed, located and documented in reports by service technicians, usually commissioned externally, using individual sensors or various devices. Continuous monitoring usually does not take place and the data can neither be networked nor connected to ERP systems. 

The sUSe platform developed at the IMMS forms the basis of a worldwide novel, holistic monitoring system for compressed air systems. It consists of the platform and several ultrasonic and volume flow sensors that are distributed over a compressed air system, networked and permanently installed. 

On the one hand, volume flow sensors from the partner Postberg measure the amount of compressed air flowing through at various points in the system. This is related to the quantity fed into the compressed air system. On the other hand, ultrasonic sensors from SONOTEC GmbH, which are also integrated in the system, acoustically locate leaks and evaluate their loss. 

With the sUSe platform, all data from a wide variety of sensors are merged and digitally processed. This data fusion enables a comprehensive evaluation, because now leakage points and total volume flow are considered together. As a result, the share of losses in the total consumption of compressed air can be precisely allocated. 

"With this completely new concept of evaluating compressed air losses holistically, companies can concentrate on the major construction sites with sound data," Hutschenreuther continues.

"After all, about 70 percent of compressed air losses can be attributed on average to about 10 percent of leaks, which you can now target and eliminate first with maintenance measures."

Electronics platform, AI-based signal processing, communication solution, performance features 

Since compressed air is supplied in varying quantities at changing points for many applications, such as for various actions of an industrial robot, the sUSe platform and all associated sensors must operate synchronously in terms of time. Therefore, IMMS has taken a modular approach to the design of the hardware components. The sensors acquire data simultaneously via a synchronization mechanism to ensure the real-time capability of the system. The algorithms implemented by IMMS are used to evaluate the different channels within the system and make a statement. AI accelerators can be retrofitted via an expansion slot to significantly increase processing power. 

This edge AI platform for decentralized data processing is used for each measuring point of the monitoring system. In order to be able to adapt the system very flexibly for different applications without having to make changes to the hardware, the IMMS developed the signal processing components using a model-based design technology and configured the application algorithms for FPGA integration on this basis. Suitable communication interfaces and protocols were implemented for integration into maintenance systems and the corresponding communication capability of the platform was established. 

In detail, the platform offers a completely digital data structure, sampling rates up to 400 kHz for synchronous and phase-accurate sampling for analog and digital sensors, broadband measurements, exchangeable algorithms, scalable computing power, sensor data fusion, calibration function, cloud integration and networking via various techniques and protocols, and connectivity to ERP systems.

Market launch 2023 and potential for further applications 

"In view of the current dynamics on the subject of energy saving, the market launch planned for 2023 comes at the right time," says Michael Münch, Managing Director of SONOTEC GmbH. Beyond the monitoring of compressed air systems, he also sees versatile application potential in predictive maintenance, process monitoring and quality assurance. He added that the modular platform architecture has been developed in such a way that very specific market requests can be effectively handled with different sensor combinations. "We assume that completely new market segments can be opened up with the technology," Münch concludes.

About the Innovationspreis Thüringen 

The Innovationspreis Thüringen annually honors outstanding innovations from Thuringia. The aim is to honor innovations as well as the players behind them and to motivate companies to incorporate the competitive factor of innovation even more intensively into their corporate philosophy and to make greater strategic use of it. The competition shines a spotlight on innovative achievements, publicizes success stories, supports networking and achieves greater visibility beyond the borders of Thuringia. With a total of 100,000 euros in prize money, the Innovationspreis Thüringen is one of the most highly endowed state innovation prizes in Germany and is awarded in four categories. An independent jury of regional and national experts from business and science evaluates the submissions according to, among other things, degree of innovation, entrepreneurial performance and market potential.
