An Example Smart Building Network Based on HD-PLC

HD-PLC is the new standard for high-speed wireline networks. Based on the IEEE 1901 and ITU-T G.9905 international standards, HD-PLC offers megabit speeds over up to several kilometers of wiring (AC/DC powerlines, twisted-pair, coax, phone lines, etc.). The combination of high-speed, long-distance communication, and physical media flexibility makes it well suited for a wide variety of building automation systems (BAS).

In this article, we review an example smart building network built using HD-PLC. This network can integrate multiple systems found in modern smart buildings, including IP cameras, environmental sensors, security systems, building comfort systems, lighting, and more. Thanks to HD-PLC’s multi-hop technology, any node can act as a repeater to extend network range and robustness. This network can scale to support up to 1024, distributed across the building, using any wiring available.

 


 

Support High-Bandwidth Applications

Originally developed for multimedia networks in residential applications, HD-PLC supports blazing-fast megabit data rates (up to 240Mbps, PHY) over powerlines and other physical media. It has since been enhanced with industrial-grade robustness mechanisms to ensure reliable operation in smart building systems. These characteristics make it well-suited for IP camera networks.

The left side of the network diagram shows a standard CCTV surveillance application using HD-PLC CCTV-IP cameras. HD-PLC uses IP-based communications (IPv4 or IPv6 multicasting) to encapsulate packets as UDP messages. This means that IP cameras are able to draw power from the main supply and also use it to transfer high-definition video to the central surveillance station. This simplifies the deployment of IP-based CCTV systems, since you don’t need to install new wiring to support the bandwidth required by these cameras.

Develop Faster, Smarter LON Systems

In 2017, LonMark adopted HD-PLC as the new standard for high-speed wireline networks. Compared to the previous LonWorks solution that was limited to 78kbps over twisted-pair and just 5.4kbps over power line, HD-PLC brings a significant speed advantage to wired control networks. Now system designers can get the cost savings of using existing wiring infrastructure along with the bandwidth they need to build smarter systems.

The right side of the network diagram illustrates a typical LON building automation scenario. The backbone for this network is provided by the main power line, to which a variety of standard LON systems are attached. HD-PLC is fully compatible with LON, and all of the devices are able to behave exactly as they would in any other LON system.

At the top of the diagram is the LON network server (LNS) with SCADA and BMS clients. LonMaker for Windows is another client that one might use in this network to manage installation and maintenance software. These clients are easily connected to the powerline backbone using an HD-PLC/Ethernet adapter.

Connected below the LNS database are HD-PLC LON nodes. These can be connected directly to the powerline, as in Section A. Alternately, they can be connected to an Easylon® HD-PLC router from Gesytec (Sections B and C), which enables seamless translation from HD-PLC LON to other LonWorks channels like the familiar TP/FT-10 physical layer.

In this smart building network example, HD-PLC replaces the existing LON/IP backbones, which require costly Ethernet cabling. By using the same wiring infrastructure used for power distribution, HD-PLC greatly reduces installation cost. It also improves system reliability, since the backbone is now independent of other IT equipment like Ethernet switches.

Simplify Network Deployment and Management

System integrators appreciate the simplicity of HD-PLC. Its built-in multi-hop technology takes the guesswork out of network planning and design by providing the plug-and-play simplicity of a mesh network. With this technology, the nodes in the network dynamically calculate route cost and select the best route based on link quality. This eliminates bottlenecks and improves robustness, since the network will automatically reroute traffic if any given node fails.

MegaChips HD-PLC solution comes with Network Manager software that makes it easy to configure, monitor, and manage complex networks. The bottom of the network diagram shows how the installation laptop can be connected using an HD-PLC/USB adapter to easily manage the network. Simply plug the HD-PLC/USB adapter into any power outlet, and you’re instantly able to connect to the building automation network.

I've also been making use of Brinks during the last 7 years and recognized I was shelling out too much. There are some very good home security system monitoring alternatives to be found that can be in a nutshell about half the cost for the very same level of service. Worthwhile researching to save some moolah mainly given that a few do not demand any commitment that the big guys require. Waste.

I've also been using ADT Security for the last five years and suspected I had been handing over way too much. Currently there are some great security monitoring choices to choose from which happens to be effectively half the selling price for the matching level of service. Definitely worth investigating in order to save moolah most definitely since a number of do not require any commitment which the big dealers demand. Shame.

I actually have been making use of ADT for the last 5 years and was aware I'd been paying much too much. Presently there are several nice security system monitoring choices available that happens to be quite simply one half the amount for the very same level of service. Truly worth exploring to avoid wasting some hard cash especially considering the fact that many do not demand any commitment that the big dealers demand. Shame. Has any one put into use https://safehomecentral.com or https://affordable-alarm-monitoring.com for security alarm monitoring yet? The costs seems to be reasonable but always curious in other's reviews when trying anyone different.

We have been using Protection 1 during the last 6 years and assumed I have been shelling out much too much. There are a handful of outstanding alarm monitoring choices these days which can be more or less 1 / 2 the selling price for the matching level of service. Definitely worth investigating to save bucks especially due to the fact some don't require any commitment which the big dealers require. Waste. Has anyone used https://safehomecentral.com for burglar alarm monitoring as of yet? The cost appears excellent but often curious in other's information when attempting someone different.
