Problems solved by technology

[0006] Most of the existing bus voice station announcement systems are manually operated by the driver, which is prone to omission and misreporting
Since the prompt sound of the bus voice station announcement system is constant, when there are many people in the bus and the environment inside the bus is noisy, the prompt sound is often submerged by the noise. missed the next stop

Embodiment 1

[0032] If the vehicle-mounted receiving module receives the information transmitted by the transmitter at the next station---Xinjiekou bus station, it means that the bus that is running is still five minutes away from Xinjiekou station, and this information will be transmitted to the central processing unit, and the central processing unit transmits the information instruction of "coming soon to Xinjiekou Station" to the voice broadcast module. The environmental noise input unit in the voice broadcast module receives the environmental noise signal, and converts the environmental noise signal into a digital environmental noise signal by analog-to-digital conversion, and outputs it to the environmental noise processing unit; the environmental noise processing unit reverses the digital environmental noise signal The digital environmental noise signal with the opposite amplitude and opposite phase is obtained by phase processing, and the gain is adjusted, and then output to the spe...

Abstract

The invention discloses an automatic bus-stop reporting device and belongs to the technical field of voice prompt equipment. The automatic bus-stop reporting device comprises a vehicular receiving module, a central processing unit, a voice playing module, and a power supply module. The voice playing module comprises an environmental noise input unit, an environmental noise processing unit, and a voice output unit. The environmental noise input unit is used for converting an analog environmental noise signal to a digital environmental noise signal. The environmental noise processing unit is used for inverting the digital environmental noise signal in order to obtain another digital environmental noise signal with the same amplitude and an inverted phase and performing gain adjustment on the another digital environmental noise signal. The voice output unit is used for receiving and performing digital-to-analog conversion on the digital environmental noise signal subjected to gain adjustment and then superposing an obtained signal on an audio file in a silent environment and outputting the final signal. The automatic bus-stop reporting device automatically adjusts the volume of the voice playing device according to the environmental noise in a bus, thereby being very intelligent.

Description

technical field [0001] The invention relates to an automatic bus stop announcement device, which belongs to the technical field of voice prompt devices. Background technique [0002] Due to its traffic network covering the whole city, the bus has become an indispensable means of transportation for people to go out. In order to improve work efficiency, buses operating in large and medium-sized cities only need to have one driver in each bus by setting up an automatic coin-operated system and a voice announcement system in the bus. The voice station announcement system can remind passengers of the arrival location and time of the next station, which brings great convenience to passengers. [0003] The application number is 201210275329.X, and the application date is August 5, 2012. The patent application discloses a bus arrival reminder system, which is composed of a vehicle-mounted terminal, a network server and a client. The intelligent device of the positioning module and...
