HomePort: An intelligent home control system

In the last couple of year's computer based home control systems are getting more and more common in modern homes. For instance these systems take care of light control, heat control and security systems. The latest trend is to use wireless communication like Z-Wave and ZigBee to interconnect different components in these systems. One of the characteristics is that each system, like for instance heat and light, has their own specific way of using the communication system. This paper describes a way to connect different home control systems through an intelligent gateway, called a HomePort. The HomePort consists of a number of subsystem communication drivers, a virtual communication layer, an interpreter and a PC-based compiler for a high level control language, called GIL (gateway intelligence language). The focus in this paper will be on the upper two layers in the HomePort, the interpreter and the application layer.
