The utility model relates to the technical field of
sports equipment, in particular to a three-antenna
wireless command sender. The utility model provides a three-antenna
wireless starting device which comprises a shell, an MCU main control board,
wireless serial port modules and a switch button, a battery is arranged in the shell, the three wireless
serial port modules are integrated on the MCU main control board, sending of the three wireless
serial port modules is controlled through the MCU main control board, and the wireless serial port modules are connected with the switch button. According to the wireless starting device, the accuracy and reliability of instruction receiving of the wireless starting device are effectively improved, timing and zeroing are performed through the switch button, the operation is simple, and the practicability of the wireless starting device is improved. The technical problem that in the prior art, in the
electromagnetic interference environment, the accuracy and reliability of the timing equipment for receiving the instruction of the wireless command sender are poor is solved, and the aim that the timing equipment can accurately receive the instruction sent by the wireless command sender in the
electromagnetic interference environment is achieved.
