Electronic Repairing & Product Development
Successful Projects
Services done to Sri Lanka Railway
In order to improve the train service in year 2000, ten Class M9 locomotives were imported from ALSTOM France. As the new technology was not well known repairs and maintenance work was not done as required and eight locomotives were out of operation for last few years. ITI engineers diagnosed the faults on the engine control unit and repaired them within a reasonable time frame. Therefore SLR was able to launce another M9 locomotive for service. More information »
Services done for Rice Research Institute-Bathalegoda
A request was made by Rice Research Institute (RRI) at Bathalegoda to repair faulty laboratory equipment. Upon inspecting the equipment the ETL engineers were able to repair all the equipment worth millions of rupees.
Automated Weather station
ITI received the first offer for the weather station in end of 2010, from Department of National Botanical Gardens to purchase an automated weather station to install at new dry zone botanic garden at Hambanthota. More information »
Wind Speed Measurement System
An order for the first wind speed measurement system was requested by BAM Holding (Pvt) Ltd. Additionally a wind data logger was developed with the anemometer and the wind wane. The system was designed in such a way to mount outdoor environment and to withstand corrosion effects near sea side installations. More information »
Automated Rain Gauge Project
According to the offer given by the Department of Meteorology we were able to supply twenty automated rain gauge stations in year 2008. All station were installed for online rainfall monitoring. This helps a lot to issue early warning messages to public during continuous rainfall. More information »
Initial Studies to Improve the Expertise
RFID Access System and Ticketing System
RFID is a wireless short distance technology that is simple in working principle but has great benefits. RFID has applications in logistics, passports, tickets, toll roads, library, etc. A study was carried out to understand the principle of RFID and its modules. Using this exposure two separate projects were designed, a RFID based ticketing system and a RFID based secure door access system.
The RFID based ticketing system was developed into initial stages with the software interface developed and interfaced to the RFID card through the PC. The RFID based secure door access system was developed in terms of hardware and software and tested at the Electro Technology Laboratory. The initial design and development was successful, however there is scope for further improvement.
GPS Tracking System
GPS provides reliable location and time information in all weather and at all times and anywhere on or near the Earth when and where there is an unobstructed line of sight to four or more GPS satellites. This feature could be adapted to various applications such as real time asset tracking, traffic guidance, etc. The initial study was to interface a GPS module to a PC and through Google Earth (free application), the position could be tracked. The data from the GPS could be stored for further analysis to retrace the path or sent in real time through GPRS for real time position tracking.
Automated Street Lamp System
Street lamps are very important to keep the cities and surroundings alive during the night time. However with the recent energy prices it is necessary to find some alternative solutions to do the street lightening. Even the LED street lamps with solar systems are available in the market it is not feasible to replace the existing street lamps with this technology. Therefore it is necessary to find some alternative solution to use the existing street lamps around the country effectively.
It is a common observation that the street lamps installed in some locations are operative during the day time due to unplanned maintenance. This situation is present in Colombo city limits as well. This is mainly due to the manual operation of the street lamps. The energy that waste due to improper operation of the street lamps is very huge. This makes a considerable impact for the economy of the country and in several ways. In order to address the above issue an automatic street lamp controlling system was designed and tested for harsh operation.
According to the discussion that we had with the Colombo Municipal Council (CMC) they use photocell based automatic street lamp controlling systems. But due to maintenance issues some of the systems failed. However the system developed by ITI does not have the above maintenance issue since it uses a timer technology. Also the system is adjusting its ON/OFF time according to the seasonal changes. At the moment CMC had requested to install three units in Colombo city as a pilot project. Depending on the success of this project a technology transfer option will be considered.
