Detailed Description
Embodiments of the horn opening platform for directional vehicles based on orientation detection according to the present invention will be described in detail with reference to the accompanying drawings.
The automobile horn is divided into an air horn and an electric horn according to sound power; the shape of the device is divided into three types, namely a cylinder shape, a spiral shape and a basin shape; the loudspeaker is divided into a high pitch loudspeaker and a low pitch loudspeaker according to the sound production frequency.
The air horn operates on the principle that a metal diaphragm vibrates to generate sound by using the airflow of compressed air, and therefore, the air horn is required to be used above an automobile with an air compressor. The air horn is generally arranged on a motor bus and a heavy truck, and particularly when a long-distance transport vehicle runs in mountainous areas or bends and other places, the air horn buzzes, so that the attention of pedestrians and drivers of opposite vehicles can be effectively reminded. Because the air horn has large volume and good aftersound, the sound is pleasant and the sound is far from the propagation. The air horn is generally cylindrical and uses two horns, high pitch and low pitch, to work in combination.
The working principle of the electric horn is to make the metal diaphragm vibrate by utilizing electromagnetic attraction to make a sound. The horn is widely applied to automobiles, is divided into three types, namely a cylindrical shape, a spiral shape and a basin shape according to the structural form, and is generally made into the spiral shape or the basin shape.
The commonly used electric horn can be classified into a mechanical type and an electronic type according to its operation. The electronic horn is divided into a contact type and a contactless type. The contact type electric horn controls the on-off of the exciting current in the electromagnetic coil by utilizing the closing and the opening of the contact, so that the iron core (or the armature) moves up and down at a certain frequency. And the metal diaphragm is vibrated to generate sound. The contactless electric horn uses electronic circuit to control the on-off of exciting current in electromagnetic coil, so that the iron core moves at a certain frequency and drives the metal diaphragm to vibrate to produce sound.
The electric horn has the advantages of convenient energy, simple structure, small volume, small mass, small noise, easy maintenance, loud and bright sound, pleasant tone quality and the like.
The contactless electric horn overcomes the defect that the horn is changed in sound due to ablation and oxidation of the contact type electric horn, thereby being more durable. And its tone and volume are easier to adjust than the contact type, so it is a development direction of the horn of the car.
Fig. 1 shows a diagram of the internal wiring of a horn for vehicles according to the prior art of the present invention.
At present, the usage mode of the vehicle horn is single, namely when a driver finds that a nearby human body or a vehicle body exists around, the driver presses a horn starting mechanism of a steering wheel to implement one-way warning operation of a loudspeaker at the front end of the vehicle, and obviously, the single whistle mode has the following disadvantages: the action of whistling that sets up the speaker at vehicle front end is relatively poor to the human body or the warning effect of automobile body in other positions of vehicle to and when there is not nearer human body or automobile body at the vehicle front end, this kind of operation of whistling causes the puzzlement to the human body or the automobile body of vehicle front end, causes noise pollution to the vehicle front end environment simultaneously.

Except for the fact that it contains many statements with hardware features, the linguistic form, description style, and syntax of VHDL are very similar to a general computer high-level language. The structural features of the VHDL program are to divide an engineering design, or design entity (which may be a component, a circuit module or a system) into an external (or visible part, and port) and an internal (or invisible part), which relate to the internal functions and algorithm completion of the entity. After an external interface is defined for a design entity, once its internal development is complete, other designs can invoke the entity directly. This concept of dividing the design entity into inner and outer parts is the fundamental point of VHDL system design. VHDL has powerful language structure, and can describe complex logic control by simple and clear source code. The method has a multi-level design description function, is refined layer by layer, and can directly generate circuit level description. VHDL supports the design of synchronous, asynchronous, and random circuits, which is incomparable with other hardware description languages. VHDL also supports various design methods, both bottom-up and top-down; the method supports both modular design and hierarchical design.
