Provided are a smart full frequency domain 2.4G unidirectional frequency hopping communication method and system. The method comprises: during code matching, a transmitter is near to a receiver, bidirectional communication is performed to implement code matching, and after code matching is successful, the transmitter and the receiver both possess an independent identification code and an independent original communication frequency, and synchronisation is established; in subsequent data transmission, unidirectional communication is adopted, and data need not be returned for confirmation, in order to increase the communication distance; each time data is transmitted, a data frame comprises the following information: a synchronous clock + reservation channels 1-N + data 1-M; the reservation channels 1-N are randomly generated by an MCU in the transmitter, and channel values within 1-N are different from one another. The system implements non-directional frequency hopping, increasing adaptability, and full frequency domain frequency hopping, reserving more devices spaces, and efficiently utilising frequency resources; during data transmission, unidirectional communication is used, and the receiver need not return data; the present invention is suitable for long-distance remote control. |
