Step S2: the control module 2 receives the voice information and sends the voice information to the voice output module 3;

step S3: voice output module 3 reports voice message output, and control module 2 sends control signal to mutual visual module 4 demonstration simultaneously.

In step S3, voice driver module 31 adjusts the broadcast volume of the voice message, and the speaker broadcasts and outputs the voice message, and in interactive visualization module 4, the light emitting diodes execute the control signal, and the number of turned-on light emitting diodes is directly proportional to the input intensity of the voice message. When the control module 2 does not receive the voice message, the control module 2 sends a waiting signal to the interactive visualization module 4 again within the preset time, the light emitting diodes in the interactive visualization module 4 are turned on, and the number of turned-on light emitting diodes is in direct proportion to the broadcast volume.

Specifically, it is assumed that the interactive visualization module 4 is composed of N _ max light emitting diodes, and when the broadcast key is not operated, the light emitting diodes are in an off (not _ work) state, and the light emitting diodes are off (not on); when a broadcast key is pressed for a long time, the control module 2 sends a waiting signal to the interactive visualization module 4, the working state of the interactive visualization module 4 enters a waiting signal input (waiting _ input) state from a closing (not _ work) state, at this time, the number of the light emitting diodes which are opened is N _ wait, the N _ wait light emitting diodes are in direct proportion to the broadcast volume, and the N _ wait light emitting diodes are equal to the N _ max light emitting diodes when the broadcast volume is maximum; when the control module 2 receives voice information, the control module 2 sends a control signal to the interactive visualization module 4, the working state of the interactive visualization module 4 is adjusted from a waiting signal input (waiting _ input) state to a receiving signal input (getting _ input) state, at the moment, the number N _ get of the light-emitting diodes which are turned on is in direct proportion to the input intensity of the voice information, and N _ get is more than or equal to 0 and is more than or equal to N _ wait; when the control module 2 does not receive the voice information, the interactive visualization module 4 enters a waiting signal input (waiting _ input) state again within a preset time (for example, 2 seconds), and at this time, N _ wait LEDs are normally white and bright; when the broadcast key is released, the working state of the interactive visualization module 4 is a closed (not _ work) state, and the light emitting diode is closed.

The vehicle voice broadcasting system collects voice by adding the voice input module, the voice output module broadcasts the voice of a driver in a vehicle to the outside, for example, when the driver needs to reverse the vehicle, the driver directly gives a voice to ask you for backing up, the voice input module acquires the voice information, the voice output module externally broadcasts the voice information, pedestrians can directly know the intention of the driver, information communication between the driver and surrounding pedestrians, cyclists and drivers is greatly promoted, the intention of the driver is directly transmitted to the pedestrians and the cyclists, the requirement of the driver is timely and flexibly conveyed, the pedestrians can conveniently know the intention of the driver, the adaptability is wider, the driving safety is effectively improved, the interactive visualization module is added, the driving safety is further improved, the driver can conveniently adjust the broadcasting volume of the voice output, the use experience of the driver is improved. On the other hand, due to the fact that the vehicles, the pedestrians and the cyclists directly interact with each other, the pedestrians and the cyclists can know the intention of the driver conveniently, unnecessary whistling is reduced, and noise pollution of cities is further reduced.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by the worker in the light of the above teachings without departing from the spirit of the utility model.
