Flood Triggered Automated Camera System (FTACS)

When the Department of Natural Resources of Australia decided that they needed to capture data about the natural flooding of a cave, they turned to a hacker to get results. The goal was to photograph the area during these floods with an automated system. In the end, they used a gutted Lumix digital camera mounted in a trash can, covered in aluminium foil. Though it sounds a bit silly, the final product turned out quite nice. You can see the build log, schematics, and results on the project page.

In this case the event they are trying to capture pictures of a cave flood with a Flood Triggered Automated Camera System. The system consists of a camera that is connected to a moisture sensor so that the a camera can start taking pictures when the sensor gets wet. Pictures will continue to be taken every 15 minutes until the moisture levels go back to normal. Since it is being installed in a remote location it needed to be self sustaining.

The water sensor is an interesting design since it has the ability of killing the power to the entire system when the conditions are dry. This is done by using a Darlington transistor feeding a relay.

Sometime, the GPRS coverage & priority issue is a turning down subject in our AVLS operations. Despite of GPS data errors and interferences, we choose to add SMS  mode for failsafe function to our AVLS architecture. It’s not really a big deal to develope the back engine, but in considering the alarm dispacthing functions. Maybe, it will become another turning down factor in our bussiness. the dispatcher should be really intelligent to determine the raw data despite of many of uncertainty factors that always bother. We bought a quad-core dell 1U rack server in order to replace our old beloved application server, a 4 pentium 4 Dell 5U tower server. We done doing upgrades to database server, and now working on the back-end & front-end application test. In another hand, we are migrating the Telemery System for waterworks…. developing a friendly GUI for Flood Monitoring System plus testing the alarm dispatching functions, still handling data loses in ABB EM meters integrations… sigh!
