Embodiment
Embodiment 1
As shown in Figure 1, 2: a kind of vehicle safe driving voice prompting device comprises the humidity sensor 1L2 that is arranged on the car body, the control module 2U3 that is connected with the humidity sensor 1L2 of institute, speech chip 3 and the loudspeaker 4U2 that is connected with described control module 2U3 successively; The probe of described humidity sensor 1L2 is located at door outside, humidity sensor 1L2 is the reed humidity sensor, the signal that humidity sensor 1L2 detects is judged through described control module 2U3, and the default voice of controlling in the described voice signal spread out of through described loudspeaker 4U2, are provided with voice power amplifier 5 between described speech chip 3 and the described loudspeaker 4U2.
Control module 2U3 adopts the PIC16F73 chip, also can select the PIC16C73 chip for use, when program design and corresponding port when using, RA0-RA3 pin that need control module 2U3 is set to the analog input mouth, other input ports are arranged to the high-low level detection and are got final product, and the voice in the speech chip 3 can be directly to the speech chip 3 that default voice are sent in producer's customization.
Humidity sensor 1L2 is mainly used in the vehicle ' that detects rainy day, carefully drives the driver who travels in the rain so that remind.Humidity sensor 1L2 adopts reed humidity sensor L2, and when not raining water erosion, reed humidity sensor two reeds separate and middle no any conducting medium, make humidity sensor 1L2 be output as high level; When rainwater watered reed humidity sensor L2 two reeds, because two reeds are separated by very closely, rainwater becomes conductor made humidity sensor 1L2 be output as low level.The low level output of reed humidity sensor L2 is delivered to control module 2U3RB2 pin and is carried out the signal judgement.After the RB2 pin detects low level, system will report " the rainy day driving please notes safety " if reed humidity sensor L2 is low level always, then every 30 minutes newspapers once, note driving to remind the driver.Certainly, more accurate for making testing result, reed humidity sensor L2 probe can be installed on door outside, fall under water as long as the sky is rainy, but then the reed humidity sensor arrives with regard to Sensitive Detection.
Be connected with the displacement transducer 6 that detects vehicle launch on the described control module 2U3.Vehicle launch detects by displacement transducer 6 and detects realization, testing circuit is by displacement transducer among Fig. 26, grievance parts such as U1D are formed, when displacement transducer 6 detects displacement signal, and after the amplification shaping of U1D is handled, signal is passed to the RA3 pin of control module 2U3, be used for vehicle launch and detect identification and prompting.
After the car key energized, control module 2U3 is with all measuring abilities of initialization.First function that detects is exactly whether the RA3 pin of seeing control module 2U3 has signal to occur, and whether reaches predetermined level degree, and the signal that detects because of displacement transducer 6 is output as simulating signal, if translational acceleration is fast more, then output quantity is just big more.So the RA3 pin is arranged to the analog sampling mouth, can realizes easily that vehicle launch detects.
After detecting enabling signal, loudspeaker 4U2 sends the voice suggestion of " this is had a pleasant journey to wish you ".
When vehicle launch after three minutes, fasten seat belts in order to remind the driver, the voice suggestion of " for your safety, Buckle Up " is then arranged.
Be connected with the mercury cut-off 7 that detects pavement behavior on the described control module 2U3.In the vehicle ' process, can run into the very poor situation in road surface, make vehicle electric wave or other security incidents take place significantly.The vehicle ' road conditions detect by mercury cut-off 7 detection signals, when the road surface is steady, mercury cut-off 7 generally can not move, the RB7 pin of control module 2U3 detects and is low level, but when running into the road surface situation when very poor, then mercury cut-off 7 is started working, and promptly high level pulse occurs on the RB7 of control module 2U3 pin, can detect the bad information of road conditions.
After jolting significantly appears in vehicle, prompting device will have the voice suggestion of " road conditions are bad, please note safety ", after its prompting mode is prompting for the first time, the secondary prompting just can occur after 30 minutes.
Be connected with the light sensor 8 that detects the weak degree of light intensity on the described control module 2U3.When vehicle ' during at foggy weather, the driver wants SC, is used to detect the sensor in greasy weather and is finished by photosensitive detection circuit and humidity measuring circuit combination, and light face testing circuit is made of R25, VD3.
To detect ambient brightness low to a certain degree the time when photosensitive, in addition if any the mist crystallization when the humidity sensor 1L2 reed, system is then thought at the greasy weather driving vehicle, when travelling in the greasy weather, then loudspeaker 4U2 sends the voice suggestion of " greasy weather travels; please note safety ", its prompting mode be preceding once the prompting with after once the prompting be separated by 30 minutes.
In addition, because night, light was very dim, can detect the driving at night with the mode of photosensitive detection, when when driving a vehicle night, then loudspeaker 4U2 sends the voice suggestion of " night, driving please noted safety ", and points out and be spaced apart 30 minutes.
Be connected with the high-frequency signal monitor 9L1 that detects the communication apparatus operation conditions on the described control module 2U3.Mainly be to travel at the driver to connect in the way or big mobile phone etc., whether this class communication apparatus working state detecting method can utilize " cell phone incoming call sudden strains of a muscle " detection high-frequency emission signal of selling on the market to exist.Because mobile communication equipment in use, can constantly send high-frequency signal to the service equipment station, promptly have stronger high-frequency energy radiation, utilize " the cell phone incoming call sudden strain of a muscle " of selling on the market can detect book and have or not the phenomenon of making a phone call, physical circuit is seen devices such as L1 among Fig. 2, VD1, VD2.Occur if control module 2U3 RA3 pin has detected signal, then loudspeaker 4U2 can send the voice suggestion of " travel in the way, please do not phone with mobile telephone ".But, when vehicle is in halted state, call in if any phone, continuous three voice suggestions of " you have phone, please answer " are then arranged.
Be connected with the alcohol sensor 10 that detects alcohol concentration on the described control module 2U3.Utilize alcohol sensor 10, can the air of finite concentration alcohol content be detected, the circuit of the quick detection of relevant wine has been selected the filament sensor for use, the utility model is after the RA1 of control module 2U3 pin detects certain amplitude, then loudspeaker 4U2 sends the safety for you, please do not drive " voice suggestion, and every 5 minutes the prompting once.
Be connected with the door magnetic detector 11 that detects the car door open and close on the described control module 2U3.Utilize door magnetic control system mode, can whether close the car door of vehicle in travelling and detect, because at present a lot of vehicles all are equipped with burglar alarm, so can directly extract signal, behind vehicle launch, not shut car door if the door magnetic signal detects from the door magnetic signal lines of alarm, be that loudspeaker 4U2 has the voice suggestion of " car door does not shut; please detect ", in order to be simple and easy to system, the signal of four car doors adopt " with " form.
