The invention discloses a communication apparatus between bus and bus station platform. The communication apparatus comprises the following elements arranged on a bus station platform: a control key, a first microcontroller, a first wireless receiver and a first wireless transmitter. The communication apparatus also comprises the following elements arranged in the main control console of the bus: a second wireless receiver, a second microcontroller, a display screen distance sensor and a second wireless transmitter. The control key, the first wireless receiver and the first wireless transmitter are connected with the first microcontroller; the first wireless transmitter and the second wireless receiver communicate through wireless signals; the first wireless receiver and the second wireless transmitter communicate through wireless signals; the second wireless receiver, the second wireless transmitter, the distance sensor and the display screen are connected with the second microcontroller through the control circuit. According to the invention, a bus driver can know instantly whether there are passengers to board the bus in an approaching bus station platform. If there are no passengers to board or get off, the bus does not have to stop at the platform, therefore, effectively saving fuels and the traveling time as well.
