Description
Technical field
The present invention relates to a kind of information presentation system, particularly a kind of prompt system of transport information.
Background technology
For the support vehicles driving safety, The coast is clear, it is very important that traffic prompting and sign are arranged.In the technology formerly, be mostly with traffic notice board, traffic lights, road sign or traffic police commander etc. for traffic prompting and sign.As a kind of Traffic alarm light circuit control device that Chinese patent (ZL) 200420027288.3 provides, it can and brightly light or close warning lamp automatically according to the dark of ambient light.It is to warn traffic with the bright or blink states of warning lamp.Chinese patent (ZL) 03222111.8 provides a kind of multifunctional safe traffic alarm device, and it can directly provide warning lamp, fog lamp, portable lamp and automobile tonifying Qi for automobile.And for example Chinese patent 200420039011.2 provides a kind of traffic alarm board apparatus, and it is a kind of and automobile accessories, removably is connected traffic alarm board apparatus in the automobile trunk, plays warning function with warning sign.
The traffic prompting sign that is provided in the above-mentioned technology formerly, or be that warning lamp, warning sign, caution poster or the traffic police who is contained in road cross or traffic mark place directly commands; On automobile, load onto other vehicles of warning such as warning lamp, warning sign or people vehicle ' is arranged.The problem that exists is abominable when environment, as to run into big greasy weather or sandstorm weather, just can't see front warning lamp, warning sign and road sign etc., and traffic just can not get safe assurance.Perhaps the driver is careful, or warning lamp, or warning sign or road sign all will be unsafe hidden danger by coverages such as leaves.
Summary of the invention
The objective of the invention is provides a kind of and can show warning in order to overcome existing problem in the above-mentioned technology formerly, can carry out the traffic prompt system of voice suggestion again.More can guarantee vehicle driving safety effectively, reduce traffic hazard, alleviate the crowding phenomenon of road.
To achieve the above object, traffic prompt system of the present invention, it comprises the interior traffic information acceptance system of the car that places in the car and places the car at road cross and traffic mark place to point out emission coefficient outward.
Comprise the receiving system central processing unit in the traffic information acceptance system in the described car, the receiving system storer that is connected with the receiving system central processing unit respectively, infrared eye, voice alerting unit and velometer interface circuit, keyboard and display unit; Described car is pointed out outward and is comprised the emission coefficient central processing unit in the emission coefficient, the infrared transmitter that is connected with the emission coefficient central processing unit respectively, emission coefficient storer and receiver of remote-control sytem.
Describedly place that the voice alerting unit of traffic information acceptance system comprises audio coder ﹠ decoder (codec) in the car, loudspeaker, microphone, input end are connected with the audio coder ﹠ decoder (codec) output terminal and output terminal is connected to loudspeaker driving circuit on the loudspeaker; Output terminal is connected with the audio coder ﹠ decoder (codec) input end and input end is connected to microphone driving circuit on the microphone.
The described receiving system central processing unit that is included in the interior traffic information acceptance system of car is embedded in and is useful on the signal of asking for receiving traffic information and running velocity, and its signal is become the receiving control system that display unit and voice alerting unit are delivered in voice suggestion.
The described car that is included in is pointed out emission coefficient central processing unit in the emission coefficient to be embedded in outward to be useful on and is received the statement number that requires the transport information that sends, and its statement number is sent to launch control system on the infrared transmitter.
As above-mentioned structure, traffic information acceptance system in the car is contained in the car, point out emission coefficient to be contained in road cross or traffic mark place outward in car.Point out the receiver of remote-control sytem in the emission coefficient to send the order that requires to send transport information to the emission coefficient central processing unit outward by car.After the emission coefficient central processing unit receives and requires to send the order of transport information, then read the statement number that sets in advance and be kept at the transport information in the storer, and the statement number information of this transport information is constantly sent by infrared transmitter (at regular intervals).When the ON/OFF key by the keyboard on the traffic information acceptance system in getting off, display unit demonstrates in voice suggestion.The receiving system central processing unit receives the speed of vehicle current driving by the velometer interface circuit, and read the scope of the speed data in the receiving system storer, whether both compare the velocity range of judging current vehicle ' consistent with previous velocity range, then read in the storer corresponding speech data as inconsistent, on the one hand by after the audio coder ﹠ decoder (codec) decoding, deliver on the loudspeaker by loudspeaker driving circuit, send voice suggestion in real time; Demonstrate by display unit on the other hand.Simultaneously, constantly survey by infrared eye in the traffic information acceptance system in the car,, then the transport information that receives is delivered in the receiving system central processing unit if detected transport information; The receiving system central processing unit is read the corresponding speech data of this transport information and by after the decoding of the audio coder ﹠ decoder (codec) in the voice alerting unit, is driven loudspeaker through loudspeaker driving circuit and send voice suggestion from storer.Simultaneously, the receiving system central processing unit demonstrates this transport information with the transport information that receives by display unit.
The effect of traffic prompt system of the present invention is remarkable:
As above-mentioned structure, traffic prompt system of the present invention can either show the transport information of front, can carry out voice suggestion again, this just overcome exist in the technology formerly because can't see the hidden danger that warning lamp, warning sign and road sign bring, make the driver predict the road conditions in the place ahead in advance.
In the traffic prompt system of the present invention, because in car, comprise infrared eye in the traffic information acceptance system, car is pointed out outward and is comprised receiver of remote-control sytem and infrared transmitter in the emission coefficient, make car launch outward transport information and Che Nei receiving traffic information to the requirement of environment and weather unlike formerly technology is desired so harsh.Become more readily available desired transport information.Therefore, the security of vehicle ' also just is guaranteed easily.
Traffic prompt system of the present invention can be constantly be prompted to the driver with voice with the velocity range of vehicle current driving, avoids driving over the speed limit etc., guarantees safe driving.
Traffic prompt system of the present invention is simple in structure, and volume is little, is convenient to install, and is easy to operate, with low cost, easy to utilize.
Traffic prompt system of the present invention is used very extensive, can be used for the traffic prompting, blind-guiding etc.; Change emission coefficient/receiving system into the low-power wireless transmitting/receiving system, also can be used for systems such as navigation.If receiving end (traffic information acceptance system in the car) is installed on the personal device, also can be used as information broadcast system among a small circle, as missing, nearby stores' advertisement, sales promotion etc.
