ProDSP Technologies has finished the development of a new generation industrial sensor under the “Funding to micro and small enterprises for innovation activities” (2018-1.1.1-MKI) tender financed by the National Research, Development and Innovation Office.

Sensor producers and industrial and logistic system providers (OEMs) in the global market are manufacturing systems specialized in specific industries (e.g. production lines, delivering and warehouse handling systems). The OEMs do not always have the needed innovation potential to keep up with the drastically improving technology. In the motion control systems they use multiple optical sensors (encoders) to sense position and other measurements, which mostly use incremental coding. These solutions have their technical limits, which make it difficult to adapt to user expectations and to develop the new generation of their products. To overcome these limits, ProDSP Technologies has developed a submicron accurate optical sensor (SpaceNC) able to measure absolute position based on a radically new principle of operation.

The result of the one and a half year long project is the prototype of a position measuring industrial SpaceNC sensor. During the project we developed the electronic, optical and mechanical parts of the sensor, a demonstration platform simulating the real operating environment and a characterization platform for characterizing the tool.

Our project lasted from January 1st, 2019 to June 30th, 2020 with a budget of 132.292.565 HUF for which ProDSP Technologies has received 94.473.895 HUF funding from the National Research, Development and Innovation Office.

The position sensing allows high-speed calculation of 2D absolute position at 100 kHz with better than 0.01 um resolution and with sub-micrometer accuracy. The applied technology also makes possible multi-dimensional measurements, e.g. 3D position of a light source by triangulation. The core technology does not change if the optical setup is different. It makes possible to apply the SpaceNC in several engineering applications.

Combination of SpaceNC 2D absolute position encoding and real-time 2D absolute position decoding techniques can be applied for reading of the 2D absolute code, which is printed on a surface. In this case the technology has excellent parameters:

  • High Precision in position sensing, i.e. sub-micrometer accuracy
  • Contactless measurement
  • Up to very high relative speed (200m/s) between the sensor and the scale

Application examples:

  • Measurement of position of a hydraulic piston
  • Determining of position of an elevator cabin
  • Real time localisation and position sensing in assembly lines in factory automation
  • 3D robot / forklift tracking
  • Deformation, load sensing, condition monitoring of machine parts, early detection of failure

Technical advantages:

  • Offering one-fit-for-all solutions, nanometer-precision, 1D to 6D contactless absolute position measurement in working volumes from <1 cm3 up to >1 km3 and beyond
  • 100-1000 higher frame rate than existing imager-based solutions up to few 100 kHz, 10-100 times larger resolution in 1D to 6D position than COTS-based Multi-D encoders today

We have reached a remarkable milestone in the SpaceNC project. The hardware development is finished in the first year of the project, the prototype sensors are manufactured. A demonstration and a characterisation platform was also developed in this period. We have started the test measurements of the sensors and we are working on a demo application. The project was really challenging because of the complexity of the development, but our developers were persistent and hard-working, so we could overcome the obstacles. The results are promising so far, it will be exciting to see the results in practice.

A new generation of industrial sensor technology will be developed by ProDSP Technologies cPlc. The project is funded by National Research Development and Innovation Office in the framework of „Funding to micro and small enterprises for innovation activities (2018-1.1.1-MKI)” programme.

Encoder Manufacturers and OEM-s are selling highly specialized products for applications in specific industries (e.g. production lines, logistics and warehouse management systems). In these systems, thousands of optical encoders are used for position sensing and other measurements, which are mostly applying incremental encoding methods. Due to their limited innovation potential, encoder producers and encoder-user-OEMs are facing difficulties to answer the market needs and to develop their next generation of products, which can’t be implemented with the State-Of-the-Art (SOA) encoder technologies. In addition, the highly fragmented market is doomed to low volume, low-profit optical encoder production, therefore they are seeking for new solutions in order to gain solid competitive advantages. In order to overcome these limitations, a sub-micron, absolute positioning optical sensor (SpaceNC) will be developed by ProDSP Technologies, based on a radically new operating principle.

The new principle of operation enables continuous condition monitoring and fault detection of the industrial equipment for our customers. By applying a new paradigm in the encoder industry, SpaceNC will be the only multi-dimensional, high-speed, industrial position sensor technology on the optical encoder market, offering solutions for new market needs, which are beyond the scope of existing encoder sensors:

  • owing to the spatial, multi-dimensional submicron precision absolute position sensing provides high-quality information, improves reliability and safety, thereby error detection becomes more effective,
  • thanks to the modular design, our encoder can be customized and applied in a wide range of applications, consequently the greater production number results lower price, compared to existing solutions.

The main result of the project will be the prototype of the SpaceNC industrial position encoder, which will be distributed as a unique product in the first business period. Electronics, optical and mechanical parts will be developed during the project period, furthermore characterization and demonstration platforms will be established in order to characterize the device and demonstrate its operation in a laboratory environment.

Our initial market segment is the EU region, main target groups are OEM-s and Encoder Manufacturers, who are willing to exploit the possibilities of SpaceNC position encoding technology.

Project duration: January 2019 – 30th of June 2020.
