Embodiment Construction

[0029] refer to figure 1 Shown is the operating environment diagram of the preferred embodiment of the traffic whistle safety warning system of the present invention. In this embodiment, the traffic horn safety warning system 10 is installed and operated in a portable electronic device 1 (such as a mobile phone, PDA). The portable electronic device 1 is connected to the earphone 2 through communication, and the earphone 2 may be a wired earphone or a wireless earphone (such as a Bluetooth earphone). The earphone 2 includes a microphone 20 . The portable electronic device 1 also includes, but not limited to, a display screen 11 , a storage device 12 and a processor 13 .

[0030] refer to figure 2 Shown is a functional block diagram of a preferred embodiment of the traffic whistle safety warning system of the present invention. The traffic whistle safety warning system 10 includes a pre-storage module 101 , a prompt module 102 , a collection module 103 , a processing module...

Abstract

The invention relates to a traffic whistling safety warning system and a traffic whistling safety warning method. The traffic whistling safety warning method comprises the steps of pre-storing a reference spectrum characteristic parameter value and a reference sound pressure value of motor vehicle horn sound in a storage device of a portable electronic device; acquiring environmental noise signals around the portable electronic device in real time through a microphone; carrying out fast Fourier transform on the acquired environmental noise signals, then carrying out digital filtering, and calculating a spectrum characteristic parameter value and a sound pressure value of the digitally filtered environmental noise signals; stopping voice signals played in an earphone connected with the portable electronic device when the difference between the spectrum characteristic parameter value of the digitally filtered environmental noise signals and the reference spectrum characteristic parameter value is less than a preset error value and the sound pressure value of the digitally filtered environmental noise signals is greater than the reference sound pressure value, and playing the digitally filtered environmental noise signals. According to the invention, the motor vehicle horn sound can be transmitted to the ears of a user synchronously, thereby prompting the user to pay attention to the traffic safety.

Description

technical field [0001] The invention relates to a prompt system and method, in particular to a safety warning system and method for traffic horns applied to portable electronic devices. Background technique [0002] Many smartphone users like to wear headphones to listen to music or make calls when they travel. During travel, due to the noisy environment, in order to enjoy music more clearly, users often turn the earphone volume to a higher state. In this case, the user may not be able to hear the siren warning sound of the car behind him, which brings certain hidden dangers to the user's personal safety. Contents of the invention [0003] In view of the above, it is necessary to provide a traffic horn safety warning system, which can collect the horn sound of motor vehicles in real time through the microphone in the earphone, and transmit it to the user's ear, thereby reminding the user to pay attention to traffic safety. [0004] In addition, it is also necessary to pr...
