Description

Speech-sounds type safety device for automobile

The utility model is about a kind of auto-safety mechanism, and particularly a kind of auto-safety mechanism that uses the voice informing mode is to guarantee the safety of running.

Automobile is in the industrial and commercial now society, the important vehicle, however also make society and vehicle drive person itself exist potential danger.Just in case car maintenance is bad, automobile spare part et out of order and driver produce carelessness etc., promptly probably driver and other people is damaged.And in the equipment of present most of automobile, do not provide sufficient safety apparatus or arrangement for detecting etc., so the potential danger of automobile, to not obtaining suitable solution so far.

In these danger factor, in fact if can be taken precautions against in advance, then should obtain adequate solution, for example, that car door does not close is appropriate, reversing carelessness, hand brake for release, hypervelocity, safety strap are not buckled well, engine speed is too high, water tank temperature is too high, the brake rubber block wearing and tearing are excessive ... Deng, though subproblem, in some car type, improved, for example, the installing one brake rubber block excessive indicator lamp that weares and teares on instrument, but this mode are for the driver, might not do suitable prompting, particularly when the driver has no time to care for appearances plate.So,, in fact benefit and not quite for traffic safety even adorned this kind indicator lamp.

Based on these shortcomings, if can provide one to detect the situation of automobile with every safety apparatus, and in time remind driver or passenger with voice mode, then the traffic safety degree will improve, and the driver can understand condition of the vehicle totally with this device, and the timely reaction when driving is also arranged.

Therefore, main purpose of the present utility model is for a kind of speech type auto-safety mechanism is provided, it can detect respectively that car door does not shut, reversing, stopping brake lock, speed per hour, safety strap, engine speed, engine temperature, water tank temperature, brake rubber block abrasion situation ... or the like situation, and inform that with voice mode the driver takes strain.Therefore, under of the present utility model assisting, will make that driving is safer, to ensure the security of the lives and property.

Other purpose of the present utility model and effect will be with following detailed descriptions, and consult accompanying drawing and more clear and definite,

Description of drawings:

Fig. 1 is control circuit figure of the present utility model;

Fig. 2 is a temperature perception circuit of the present utility model;

Fig. 3 is the utility model engine speed circuit for detecting;

It is speed sensitive part of the present utility model that Fig. 4 A-4C shows;

Fig. 5 shows it is the circuit for detecting of the utility model car door, safety strap, the employing of trunk lid.

Control circuit figure of the present utility model as shown in Figure 1, wherein, circuit has a microprocessor U1 as control core of the present utility model, its input port I/P1-I/P10 links detector 1-10 respectively, and the function of detector 1-10 is respectively the situation of automobiles such as detecting car door, brake rubber block, speed sensitive, safety strap, temperature perception, engine speed, trunk lid, reversing.Its microprocessor U1 is the microprocessor of a nibble, its have in addition X1, X2, GND, VCC, etc. the configuration of known pin position.

Fig. 2 shows the temperature perception circuit of the utility model preferred embodiment, in the utility model design, has 2 modules, and one another is the sensing engine temperature then in order to the sensing water temperature, and when temperature surpassed set point, the perception circuit triggered microprocessor immediately.In each module, include a temperature sensor s1, the temperature signal that it senses will be handled via an op amp op1, op2, op3, in a single day can when detecting temperature, promptly send an energizing signal to microprocessor U1 shown in Figure 1 by the mouth of op3 above a predetermined set-points.In this circuit, variable resistance VR1 is used for temperature and sets.

Fig. 3 shows engine speed circuit for detecting of the present utility model, and it is the operating speed that is used for detecting engine.In this circuit, detect the high tension cord of engine with a speed sensor S2, take out frequency, the treater of electric pressure converter F/V, op amp op5 is become voltage signal, send an energizing signal to microprocessor U1 shown in Figure 1 via op amp op4, frequency.Similarly, in this circuit, but power transformation becomes the setting that resistance VR2 is used for speed.

Fig. 4 A-4C shows speed sensitive part of the present utility model, for detecting speed, the utility model adopts an infrared light emitting diode 31, one infrared receiver diode 32, has a rotating disc 33 between the two, this rotating disc has porous disc structure (shown in Fig. 4 B), when this rotating disc 33 is subjected to the transmission of speed meter rete cord institute, relative infrared light will or be interdicted by the square hole on the rotating disc 33, this phenomenon will be received by infrared receiver diode 32, thereby can produce the ON/OFF interrupted singal, speed is high more, its ON/OFF frequency high more (consulting Fig. 4 C circuit), this signal will be converted into voltage signal to electric pressure converter F/V via a frequency, again with the velocity ratio of setting, produce energizing signal to microprocessor by the mouth of op amp OP6.Variable resistance VR3 is the usefulness of setting speed.

Fig. 5 shows the circuit for detecting that car door in the utility model, safety strap, trunk lid are adopted, and wherein detection switch S3 is in order to detect the usefulness of above-mentioned each signal.Resistance R 1 is a current-limiting resistance, its objective is that being used for protective circuit can not have the input of big electric current.Capacitor C 1 is a high-pass filter, and purpose is the possible misoperation in order to prevent that high-frequency signal from producing.Z1 is a surge absorber, and purpose is to absorb surge voltage in the circuit.D1 is a reverse protection diode, and purpose is when the input high pressure is reverse (bearing), can protective circuit.When this circuit does not close situation such as appropriate, that safety strap is not fastened, trunk is not built at the detecting car door, can send an energizing signal to microprocessor U1 via foregoing circuit.

Microprocessor U1 has a replacement end, is connected in reset switch RST, can be subjected to the manual reset switch of controlling usefulness as control when operation.The mouth 0/P1-0/P10 of microprocessor U1 is the input end SEC1-SEC10 that is connected among the sound circuit U2, employed sound circuit U2 is-20 seconds speech ICs in the utility model, stops to control the control that pin STOP is subjected to microprocessor U1.SEC1-SEC10 respectively is controlled to be the triggering control line, with as the usefulness that triggers sound circuit U2.Can trigger language IC and send various countries' speech.In this embodiment, send language and comprise (for example);

1. car door does not shut

2. note reversing

3. stopping brake lock is not put

4. speed per hour is above 100 kilometers

5. safety strap does not tie up

6. engine speed is too high

7. water temperature is too high

8. the brake rubber block wearing and tearing are many

Some voice signals after producing via sound circuit, are promptly delivered to the input end VIN of audio amplifier circuit U3 by its speech output end AUD, therefore, this voice signal can amplify through amplifying circuit U3, and are sent by a loudspeaker SP and to inform speech sound signal.

Via above circuit structure, and the control of microprocessor U1 inner control program, can be with the corresponding signal of each detector 1-10, correctly deliver to relative speech trigger control line SEC1-SEC10 one of them, make sound circuit send corresponding voice data to amplifying circuit, amplified broadcast.

In sum, the utility model really provides an auto-safety mechanism that has a practical value, and it can be used as the auxiliary device of running safety, may situations in time inform the driver with various.
