LGP have several gas recovery and electricity generation sites around Perth and interstate. While at LGP he code cut a SCADA (Supervisory Control And Data Acquisition) package that was used for many years until a cost effective commercial replacement was found. He also developed and made a full landfill gas engine management system using Atmel 8535 micros as the core embedded control device, some of which are now used as signal control at CMR. <br><br>Mike has been an active member at the CMR railway for over 10 years and in that time has refurbished 3 locomotives of his own and become very involved in the railways signalling system. The team at Castledare have built a new signal box at Niana and it is being developed as an automated signal control station for the Niana area rail network. It has two PC’s on Ubuntu OS and a Click PLC all controlled from a custom SCADA system implemented using Gambas3 a VB look a like. This is a very nice package and a true RAD. The Castledare signals are generally stand alone and are using Arduino Uno’s connected to our 433 mHz wireless network back to the local signal box. These signals use ultrasonic train detection or track mounted treadle switches. Some are also used to operate electro mechanical or pneumatic points at remote locations.<br><br>Mike will be showing us all this and more on the day.</div></div></div></div></div></div>
