Design Of Telephone Gateway Subsystem In Intelligent System Of Home Furnishing

With the improving of people’s living standard, intelligent homefurnishing has been rapidly developed. In order to meet the generalresidential demand for smart home furnishing, this thesis designs atelephone gateway, which can realize boththe function of automatictelephone alarm andswitching between two systems. When thegateway connect to the intelligent home furnishing system, thegateway is used as the indoor machine and at this time it not onlycan communicate with Ethernet Gate Module but also Dial thepre-set telephone numberby the alarm pulse.This paper contains three parts:the hardware design,softwaredesign and testing for the hardware.And we use AT91SAM7X512asthe hardware controller and four processes for software. Also we testthe interface and circuit of the hardware.In this design we make full use of the telephone line system laidin generally cells to achieve the goal of reducing the cost.
