Abstract
The utility model relates to automobile safety driving techniques and discloses an automobile speeding voice prompt device based on a singlechip microcomputer (SCM). The device comprises the SCM, a vehicle speed sensor, a vehicle speed setting module and a voice broadcaster, wherein the vehicle speed setting module is formed by button switches; an input terminal of the SCM is connected with the vehicle speed sensor and the vehicle speed setting module respectively; and an output terminal of the SCM is connected with an input terminal of the voice broadcaster. During speeding, the voice broadcaster is controlled to carry out speeding voice prompt by the SCM, so that traffic accidents caused by the speeding of an automobile can be reduced effectively.
Description
Technical field
The utility model relates to the vehicle security drive technology, particularly a kind of SCM Based overspeed of vehicle sound prompt device.
Background technology
In recent years, China's arteries of communication cause develops rapidly, and meanwhile, the traffic safety situation is also severe unusually, and the annual road traffic accident that causes because of hypervelocity and the personal casualty that causes thus are very outstanding.Though most of high-grade automobile is equipped with GPS vehicle overspeed alarming device at present, also there is special GPS to sell on the market, but price is all more than thousand yuan, update software also needs certain expense, for the low and middle-grade cars of domestic major part, press for the reliability height, the overspeed of vehicle sound prompt device that price is lower.
Summary of the invention
The purpose of this utility model is to provide a kind of SCM Based overspeed of vehicle sound prompt device, can be attached under the situation that does not change the car inner structure on the automobile of various models, realizes intelligent voice prompt, and is simple in structure, the reliability height, and price is lower.
For achieving the above object, the utility model is achieved by the following technical solutions.
A kind of SCM Based overspeed of vehicle sound prompt device, it is characterized in that, the speed of a motor vehicle setting module, the voice announcer that comprise micro controller system, car speed sensor, formed by button switch, the input end of described micro controller system connects described car speed sensor and described speed of a motor vehicle setting module respectively, and the mouth of described micro controller system connects the input end of described voice announcer.
Characteristics of the present utility model and further the improvement are:
Described micro controller system is selected the STC89C52 micro controller system for use.
Described car speed sensor is selected the ATS276 Hall element for use.
Described voice announcer comprises the volume adjusting unit that speech chip that model is ISD25120 and X9104 solid state non-volatile digital regulation resistance constitute.
Described speed of a motor vehicle setting module is the button switch that seven buttons are formed, seven corresponding seven different velocity standards of button.
The input end of described micro controller system also is connected with for the wireless receiving module that receives the different frequency signals pulse, and described micro controller system mouth is connected with the wireless transmitter module for the pulse of emission different frequency signals.
SCM Based overspeed of vehicle sound prompt device of the present utility model, the road standard of the limited speed that the speed of a motor vehicle of setting with the user or wireless receiving module receive, the current vehicle speed input micro controller system that car speed sensor is sensed, micro controller system is through computing and conversion, when hypervelocity, by the voice suggestion that exceeds the speed limit of Single-chip Controlling voice announcer, can effectively reduce overspeed driving car and the traffic accident that causes.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the general frame figure of SCM Based overspeed of vehicle sound prompt device of the present utility model.
The specific embodiment
With reference to Fig. 1, be the general frame figure of SCM Based overspeed of vehicle sound prompt device of the present utility model.Wherein, this device speed of a motor vehicle setting module, voice announcer of comprising micro controller system, car speed sensor, being formed by button switch; The input end of micro controller system connects the mouth of car speed sensor and speed of a motor vehicle setting module, and the mouth of micro controller system connects the input end of voice announcer.
Car speed sensor of the present utility model is finished by the ATS276 Hall element, the Hall element reliability is higher, and this sensor pin is few, and treatment circuit is simple, signal is handled easily, and signal output only just can be imported micro controller system through 1 pull-up resistor and filter capacitor.
Speed of a motor vehicle setting module of the present utility model adopts seven button switches as the device of user's setting speed.The standard of the limited speed of road roughly has 7 gears, adopts the corresponding 7 kinds of standard speeds of seven button switches, is directly inputted to the I/O interface of micro controller system, and the driver just can select 7 kinds of different speed, has so both simplified circuit layout, can improve overall degree of stability again; Wherein, wireless transmitter module sends 7 kinds of different frequency signal pulses, represents 7 kinds of different frequencies, is received data and is stored micro controller system by wireless receiving module, analyzes 7 kinds of different standard of the limited speed by software programming.
Voice announcer of the present utility model comprises the volume adjusting unit that speech chip that model is ISD25120 and X9104 solid state non-volatile digital regulation resistance constitute, and it has the 120s record playback time, can realize the voice segment recording and make up playback at random.X9104 solid state non-volatile digital regulation resistance, it has the tapping point that can be visited by sliding unit between each unit and 2 end points; The position of sliding unit is by CS, and U/D and INC3 input end control by Single-chip Controlling resistance size, reaches the purpose that improves the warning volume one by one, strengthens the warning effect.
SCM Based overspeed of vehicle sound prompt device of the present utility model, at first whether open the input micro controller system by automobile, after micro controller system receives the information of automobile unlatching, the speed of a motor vehicle that the road speed limit that receives with wireless receiving module or user set is standard, make comparisons with the current automobile speed of input micro controller system, when current automobile speed is higher than the required standard speed of a motor vehicle, micro controller system is through computing and conversion, by the voice announcer that is connected with the mouth of the micro controller system prompting of broadcasting, remind the user to reduce the speed of a motor vehicle; In addition, volume adjusting module can also be regulated the volume of voice suggestion under varying environment, can effectively reduce overspeed driving car and the traffic accident that causes.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, the utility model is not limited to above-mentioned specific embodiments, and above-mentioned specific embodiments only is schematic, guiding, rather than restrictive.Those of ordinary skill in the art under the situation that does not break away from the scope that the utility model claim protects, can also make a variety of forms under the enlightenment of this specification sheets, these all belong to the row of the utility model protection.
