Abstract: A wireless transmission system capable of automatically adjusting transmission power includes a main wireless apparatus and plural secondary wireless apparatuses, and the main wireless apparatus is capable of detecting the data rate between the secondary wireless apparatuses, and increasing or decreasing the transmission power of any one of the secondary wireless apparatuses by a master controller, or increasing or decreasing the transmission power of the main wireless apparatus, so that the data rate and/or transmitting distance between the main wireless apparatus and the secondary wireless apparatuses can be optimized.

Abstract: A radio frequency transmission system and a radio frequency transmission method are provided. The radio frequency transmission system includes a main control unit and a plurality of transmission units. The frequency transmission method includes the steps of: a plurality of transmission units being connected to a main control network of a main control unit, respectively; when any one of the transmission units transmits data to the main control unit through radio frequency, the other transmission units in a transmittable range receiving the data simultaneously; when a data transmission of the transmission unit in the previous step fails, the data transmission being restarted by the original transmission unit or the data transmission being performed by another one of the transmission units. Thereby, the retransmission efficiency of packet loss can be enhanced and the transmission efficiency of radio frequency can be improved.

Abstract: A wireless transmission device includes a wireless transmission module, a sensing module, a memory module, and a processing module. A wireless transmission system includes a plurality of transmission units and a main control unit. The transmission units are based on the wireless transmission device. Through the wireless transmission device and system of the present invention, when the data transmission of the main control unit and any one of the transmission units fails, another transmission unit having the strongest signal or the highest transmission efficiency transmits data to the transmission unit whose data transmission fails. Thereby, the wireless transmission node of the present invention has repeating and routing functions, thereby improving transmission efficiency and accuracy in wireless communication.
