A smart home signal transmission system and method comprises a transmission terminal and a control terminal, wherein the structure has the characteristics of transmission terminal contains wireless signal receiving end which receives the signal from remote control and connects with transmission line. Transmission terminal contains emitting transducer which can convert electrical signal into ultrasonic -wave signal. Transmission line can transmit ultrasonic -wave signal. The system has simple structure, easy operation and low economic cost, conducive to mass large scale application. A smart home signal transmission method characterizes in following: a) determining whether there is wireless transmission obstruction environment and carrying out wireless communication by remote control for smart home to control smart home if there is no obstruction. The signal transmission system has humane communication design and selects signal transmission mode according to the environment. By utilizing ultrasonic -wave transmission, the signal transmission system only needs to match with transducer in using, which is economic and efficient.
Description
technical field [0001] The present invention relates to a signal transmission system and method of home equipment, in particular to a signal transmission system and method of smart home. The invention belongs to the technical field of signal transmission systems and methods for household appliances. Background technique [0002] At present, the signal transmission between various smart homes mostly adopts the transmission mode of electric signal, and the transmission between electric signals is used to achieve the purpose of control and feedback. The transmission of electrical signals is susceptible to external interference, and the short transmission distance cannot realize remote control. [0003] To this end, it is necessary to design a signal transmission device and method for smart home, which can convert the control signal into an ultrasonic signal, then transmit it through the original transmission line, and then decode it at the control end to convert the received u...
