Hi everyone, I'm part of a team of engineering students who are looking to design a system that can check for fence breakages and send a message to your phone instantly, while using zero power until a breakage occurs. I would be interested to know if many people consider fence monitoring a problem, the price you would value a monitoring system at or if you have any problems that you think are more pressing. Thanks
G'day Chris, Fence repairs and maintenance can take up a lot of time, so any system that can help you determine when and where a problem occurs would be handy. I'm interested in how you this would work in practice - is it only for when a breakage occurs? Stock and wildlife can damage and put pressure on fencing infrastructure without actually causing a break. A system that can identify when a fence is being tested or breached would also be useful.
Hey Chris, breakages in fencing (e.g. cows pushing through) are quite time-consuming and expensive, so anything to alert farmers early is welcome news! The farmers I know love checking on their fences regularly; however, especially during harvest (most farms these days are mixed-farming enterprises) there is little time to check on fences. Good luck with your project! Maxie
Hi. A typical fence failure is from a tree falling across it and pressing it flat. The wires do not necessarily all break but their proximity changes as does their proximity to the ground and ground leakage. Measuring conductor continuity is therefore a bit pointless. Variation in capacitance between wires may help as might ground leakage (except in wet weather). Strain gauges on wires would be expensive but potentially viable - a fallen tree may increase or decrease strain on a fence and this strain propagates a long way. Remote area farmers spend a fortune monitoring fences by light aircraft or 4wd or motorbike circuits.
Hi Chris and other contributors to this blog. I invite you to give me a call. i am manager at Pakton Technologies, who have been involved in electric fence electronics for over 20 years. We could help you out or have you add to our development. I am interested to know if you are talking about electrified fences or non-electrified fences (which also interests us). The monitoring of security electric fences has been around for along time - usually the monitoring was seen on computers. We applied that technology to Currawinya's Bilby Fence many years ago. And now we have this technology in our Electric Fence Station (seen from computer and phone). Last year we also launched an IP Energiser with an app for checking fences. No cost for the app and no sim in the IP energiser. The best place to take a look is http://www.pakton.com.au/sec_products_IP.php or at JVA (Australian brand) http://www.jva-fence.com.au/docs/IP_Energizer_Brochure.pdf http://jva-fence.com/agric/ipenergizer/index.html I would love to hear more about your project and wish you well. it is an interesting area.

Hi Chris, Agersens (www.agersens.com) is releasing the worlds first virtual fence system later this year. Called eShepherd this GPS based system will not only enable farmers to set alerts when animals cross a fence boundary but will also shepherd them back into the paddock. It can be used to reduce pressure on existing fencing or fencing in poor repair, and is not affected by falling trees, flood, or fire. Its real value comes from being able to create and remove fences at will, and optimise stocking rate to feed availability. Rotational or cell grazing programs can be fully automated, and the system can be managed from a smartphone or tablet. The technology was developed by CSIRO and Gallagher are a lead investor in the technology. Agersens is located in SproutX in Melbourne.
