1. A intelligent home control bus having at least one input node (sensor, announcer) A and at least a output node (operator, listener) L, wherein the control instructions are input from the input node A, and transferred to the output node L through a control bus, and the output node L outputs a logic operation result based on the instructions; the network have the following features: the node A being a control device for transmitting data, node A having at least one input circuit for inputting a special logical state, and node A having at least one event data packet, wherein the node A transmits the event data packet to the bus when the state of the input circuit is varied; the node L being a device for receiving data and performing a operation, the node L having at least one output circuit for outputting a special logical state, the node L having at least one read-write memory for storing the data packet generated in the programming process; After received the event data packet transmitted from the node a through the bus, the node L compares it with the data packet stored in the memory, and determines the output logical state according to the result of the comparing.
