Summary of the invention
It is an object of the invention to overcome electric motor car in prior art to make a noise the less shortcoming that can not remind pedestrian, it is provided that a kind of electric motor car pedestrian's sound prompt device that can automatically send sound prompting pedestrian and implementation method.
It is an object of the invention to be achieved by following technical proposals:
A kind of electric motor car pedestrian's sound prompt device, including speaker and controller, is connected by audio transmission line between speaker and controller, and it is anterior that speaker is arranged on electric motor car, and controller is also connected with vehicle speed sensor and gear position sensor.Vehicle speed sensor and gear position sensor detect speed and gear information, once exceed the threshold value of setting, and controller controls speaker and sends the pedestrian around sound prompting, and pedestrian is aroused attention by sound, it is to avoid the generation of vehicle accident.
As a kind of preferred version, the sound frequency that speaker sends includes the frequency less than 1600KHz.The phonosensitive of treble frequency is declined by old people, it is therefore desirable to the especial sound frequency less than 1600KHz, increases old people's sensitivity to sound.
As a kind of preferred version, electric motor car pedestrian's sound prompt device also includes radar sensor, and radar sensor is also connected with controller.Radar sensor measures electric motor car and the distance of the pedestrian that walks, and once less than the distance of restriction, the speed of the most no matter electric motor car or gear, speaker directly sends sound prompting.
As a kind of preferred version, speaker surface is provided with circular baffle plate, and circular baffle plate is also connected with motor, and motor is connected with controller；Circular baffle plate is provided with two circular arc perforates, and two circular arc perforates are symmetrical in the circular baffle plate center of circle.Circular baffle plate can rotate, and by the circular baffle plate rotated, sound is by the same the most erratic transmission of perforate rotated, and sound size that speaker sends difference over time sends change to make pedestrian around hear, it is easier to cause the attention of pedestrian.
As a kind of preferred version, the radian of circular arc perforate is 90 ° to 120 °.
As a kind of preferred version, electric motor car front portion is provided with several vertical rotating shafts, and vertical rotating shaft is also connected with motor；Vertically it is fixedly connected with described speaker in rotating shaft.Vertically rotating shaft can adjust speaker towards, can measure, by radar sensor, the direction that the direction of pedestrian adjusts the direction alignment pedestrian of speaker.
The implementation method of a kind of electric motor car pedestrian's sound prompt device, based on a kind of electric motor car pedestrian's sound prompt device, comprises the steps:
Step 1, vehicle speed sensor obtains speed information, and gear position sensor obtains gear information, and controller obtains speed and gear information；
Step 2, if speed or gear information exceed the threshold value of setting, then controller sends control signal, and control signal sends alarm sound through audio transmission line to speaker, speaker；
Step 3, radar sensor obtains electric motor car and neighbouring pedestrian's range information, if distance limits distance less than first, then controller sends and controls signal to motor, and motor controls circular baffle plate and rotates.
As a kind of preferred version, if step 3 also includes that distance limits distance less than second, then motor controls vertical rotating shaft rotation, makes speaker towards the direction of nearest pedestrian.
The invention has the beneficial effects as follows, electric motor car pedestrian's sound prompt device can effectively remind pedestrian around to have electric motor car close, it is to avoid pedestrian does not hears the generation that the sound of electric motor car causes the accident.And pedestrian can be reminded by the present invention efficiently, considerably increase the probability of pedestrian's acoustic.Present configuration is simple, practical.
