| The intelligentized indoors communication systems are usually net-jointed in mariner of laying out line currently, we adopted the infrared wireless net-joint in order to reduce the cost and enhance the flexibility of the system. Its basic configuration is blocking many kinds of the functional circuitries which carry through communication with each other by the infrared light ,and do remote-transmission by the line of electric powers and telephone.This paper outspreaded its discussion enclosing the network design of the intelligentized indoors communication systems, and discussed deeply how to organize indoors networks, and put forward the net-jointed project based on infrared communication after comparing fully the performances of every system design projects. This paper introduced principally how to design infrared wireless net-jointed system, and expatiated the key parts in detail, such as infrared wireless communication, net-connection in lines, carrier wave in electric power line, and so on. In this paper we can realize optic-electricity transform by the modulation, demodulation, coding, decoding for the signal; we can enhance the anti-jamming and secrecy performance of the system by means of the encrypted communication; we designed all sorts of the functional circuit module in reason, and enhanced the net- jointed flexibility of the system; which operates expediently and has friendly interface by adopting the phonetic circuit ; we adopts mostly the SCM technology, which has better expansibility and lower cost .we here has successfully proposed the solution for the remote- transmission of the IrDA device in the system design and debug process, and discuss and analyze the carrier wave in the electric power.The intelligentized indoors communication systems in this paper has assed the system debugging time after time, and used in slap-up dwelling house, which proves fully its rationality and feasibility, it possess the wide market foreground.
