REMOTE MEASUREMENT AND CONTROL SYSTEMS

MONITORING AND CONTROL OF PHYSICAL AND CHEMICAL QUANTITIES

The remote measurement systems are capable of real-time collection of data, analyzing and processing. The technology can be used purely for monitoring or to control processes, e.g. to ensure a well-timed irrigation in greenhouses if the soil humidity drops, in sport halls if the air pressure reaches a critical value, or to control illumination.

OUR SOLUTIONS

The system consists of a programmable logic controller (PLC) capable of collection data from various sensors (to measure pH, humidity, solution concentrations, pressure, temperature, air humidity, carbon dioxide concentrations, etc.) and inter-integrated circuit (I²C) computer bus enabling communication.

The recorded data are exported to a secured database in short intervals, e.g. one record per second, and can be safely accessed on a local network (LAN) or internet (WAN) by the user using a web interface. The interface also allows to load the history of measurements and provides their statistical analysis. Moreover, the data can be also accessed by an external device, such as relay, to take actions based on the measured data, e.g. regulate heating or start the irrigation.

APPLICATIONS

The system is universal and the applications are limited only by the sensors. However, the capabilities of modern sensors are almost limitless with respect to common engineering applications, and their price is still decreasing. To give a few examples, the concept can be utilized for instance to measure:

  • air temperature and humidity,
  • temperature of water solutions (range -20 °C to 133 °C, IP 68),
  • pH (in the interval from 0 to 14 with resolution of 0.002),
  • electrical conductivity (3 types of sensors, ranges 0.5 - 50,000 µS/cm, 5 - 200,000 µS/cm, 10 - 1,000,000 µS/cm),
  • oxidation reduction potential (range +/- 2000 mV, operating temperature 1 °C - 99 °C),
  • oxygen dissolved in water solution (range 0 - 20 mg/L, max. temperature 50 °C),
  • pressure (2 types of sensors, ranges 0 - 7.5 PSI and 0 - 100 PSI),
  • light intensity (range 0.1 - 40,000 Lux, operating temperature -30 °C - +80 °C),
  • wind speed (range 0.5 - 50 m/s),
  • atmospheric carbon dioxide concentration (ranges 0 - 2000 ppm and 0 - 5000 ppm).

Based on the measured quantities, any device can be controlled or switched by contactors or relays.

We are proud that our system has been chosen to control optimum conditions for the Laboratory of Silence in the Czech pavilion at Universal Exposition (EXPO 2015) hosted by Milan, Italy.
