Abstract:
1. A remote communication system of a network, comprising a plurality of control units electrically connected to a plurality of external loadings, wherein each control unit serially connected to a main controller and the control unit at next stage through a transmission terminal and a transmitter, each of the control unit comprising: a signal converter electrically connected to the external loading for receiving a signal responded by the external loading and transmitting a control signal to the external loading; a microcontroller electrically connected to the signal converter for receiving a response signal from the signal converter and transmitting a control signal to the signal converter, and the microcontroller at least comprising a universal asynchronous receiver/transmitter, the universal asynchronous receiver/transmitter comprising a receiver and a transmitter, and the receiver electrically connected with a transmitter of a universal asynchronous receiver/transmitter at a previous stage and the transmitter electrically connected to a receiver of a universal asynchronous receiver/transmitter at a next stage; a switch, including a first input port, a second input port and an output port and the first input port electrically connecting to the transmitter of the universal asynchronous receiver/transmitter, the second input port electrically connecting to the microcontroller and the output port electrically connecting to a response terminal; wherein the main controller is configured to transmit a first packet to read data from a single or all control units, and the switch turns on and responds data to the main controller; the main controller is configured to transmit a second packet and executes writing data to the microcontroller if a connection index and a target unit address of the second packet are equal; the main controller is configured to transmit a third packet and writes data to all control units if a target unit address of the third packet is zero.
