DATA TRANSCEIVER OF HOME AUTOMATION SYSTEM

摘要

PURPOSE: A data transceiver of the home automation system is provided for a user to use conveniently home appliances by controlling and monitoring many home appliances connected to a PC through a single adapter. CONSTITUTION: The first transistor(Q110) works when a regular signal is inputted to a base connected to the first micro-computer(310). The second transistor(Q120) driven by receiving a control signal from the second microcomputer, cuts off the signal flowed into the second micro-computer(410) when the first transistor outputs the signal. The adapter(200) inverts the signal which is output from the first or second transistor, and transfers the signal, which is converted into the regular voltage level for the communication with a PC(100), to the PC through a transmitting end.
