A technologically oriented university from Latvia has developed software and embedded sensors network system for process control and automated decision making without human intervention. The operational information systems and technical system’s software adapted to specific applications ensures high reliability of processes and precise manipulation with objects. The embedded system is set up as a ROM chip with a stored management program and/or operating system.
The technology has passed initial field tests in agriculture industry. For the agriculture, crucial measurements included: soil and terrain parameters, such as pH and soil moisture, soil temperature and bulk density, water holding capacity, etc. All this information can be obtained by means of the analysis of optical and microwave remote sensing data, or by a set of suitable sensors placed on the field. In order to reduce the number of sensors and optimize the agricultural job, the sensors can be placed on board of tractors or other machinery that is moving within the area to be monitored.
For data transfer the technology utilizes the international standard ISOBUS. The data transfer between sensors and management/control unit usually is achieved through wireless network. The wireless sensors transmit a continuous data stream, which is remotely monitored through Farm Management Information System (FMIS).
The wireless sensors transmit every 30 seconds a data stream containing information in a digital coding through a network (Wireless Sensor Network, WSN). The ISOBUS Task Controller is deployed in a Data Management System (DMS), which gets the continuous data flow from the sensor network, then format this data stream in a defined structure and send these structures to the remote FMIS (Farm Management Information System) into the farm premises. The DMS gets stream of data from the WSN using a serial UART link. The DMS gests the localization data from a GNSS receiver (standard GPS receiver) through an ISOBUS interface. The DMS communicate with the FMIS using a GSM module hosted by the VECAN system. The DMS sends the stream of data to the VE-CAN module through the ISOBUS network.
User can connect with the system over a smartphone to command: (1) start stream (data collection and communication to FMIS), (2) stop Stream, and to display information about (3) communication channel status (working/not working) and (4) average value for each sensor.
All this facilitates faster, more productive and better performance, increases the safety of processes and reduces operational costs.
The developed system can also be applicable and even advisable in the social sphere (sick people, care of preterm babies) and in mining (manipulation of machinery and monitoring/controlling environmental parameters). The developed embedded system is cost effective, user friendly with low power consumption. Its also multi functional, miniature, efficient data processing, storage and include communication system. The systems are built into manageable objects and provide an optimal performance mode for the pre-programmed operations. The universal controller is designed for highly precise automation tasks. Software development ensures functional customization of the system.
The university is looking for commercial agreement with technical assistance including contracts for the system’s adaptation to specific needs and technology consulting. The system developers offer professional advice, to find and correct faults that prevent correct operation and provide system updates.
