Description
Technical field
The utility model belongs to the automatic control technology field, is specifically related to a kind of automobile hand brake improper use warning device.
Background technology
People use the travelling brake system through regular meeting in the driving, and brake system our parking brake of often saying just but is not held in esteem and looks.In fact, for automotive safety, parking brake and travelling brake system no less important, because of the accident that parking brake et out of order or improper use cause of common occurrence: not letting go stops just starts the error that car is new hand Chang You, serious oil consumption not only, also can cause parking brake malfunctioning because of brake facing wearing and tearing, in addition smolder on fire, jeopardize driver's life; Forgotten to pull the hand brake during if stop or parking brake is not moved the position to and just left, car may glide from the slope, gently then breaks road facility, damages car, the heavy then passerby that wounds.
Summary of the invention
At deficiency and defective that prior art exists, the purpose of this utility model is to provide a kind of automobile hand brake improper use warning device.
In order to realize above-mentioned task, the utility model adopts following technical solution to be achieved:
A kind of automobile hand brake improper use warning device, comprise interface chip, infrared pickoff, Hall element, micro controller system, alarm unit and speech chip, wherein, interface chip, infrared pickoff, Hall element, alarm unit and speech chip are connected with micro controller system respectively.
Other technologies characteristics of the present utility model:
Described interface chip adopts the MC33993 multiple way switch to detect interface chip.
Described infrared pickoff adopts the D203B pyroelectric infrared sensor.
Described Hall element adopts the ATS276 Hall element.
Described micro controller system adopts STC89C52 type micro controller system.
Described alarm unit comprises buzzer phone, AUTOMOTIVE RELAY and flasher, and described buzzer phone is connected with micro controller system respectively with AUTOMOTIVE RELAY, and described flasher is connected with AUTOMOTIVE RELAY.
Described speech chip adopts the ISD25120 chip.
This device is gathered signal with sensor, and Single-chip Controlling is reported to the police, and with speech chip auxiliary prompting chaufeur, can reduce the generation of the traffic accident that causes because of the parking brake improper use effectively, has guaranteed the safety of chaufeur.This apparatus structure is simple, and function practicality and cost are low, and be convenient for installation and maintenance.
Description of drawings
Fig. 1 is annexation scheme drawing of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail.
The specific embodiment
As shown in Figure 1, a kind of automobile hand brake improper use warning device based on technical solutions of the utility model, comprise interface chip, infrared pickoff, Hall element, micro controller system, alarm unit and speech chip, wherein, interface chip, infrared pickoff, Hall element, alarm unit and speech chip are connected with micro controller system respectively.
In the utility model, interface chip adopts the MC33993 multiple way switch to detect interface chip, MC33993 is that a programmable multiple switch detects interface device, can detect 22 way switch amount incoming signals, whether this chip is opened for detection of automobile key switch in this device, and detected on off state is sent to micro controller system by SPI; If be in opening, then send a high level signal to micro controller system; If be in closed condition, then send a low level signal to micro controller system.
Infrared pickoff adopts the D203B pyroelectric infrared sensor, be installed in the driver's seat both sides, the infrared radiation that this sensor will be surveyed and receive by detective cell is transformed into faint voltage signal, outwards output after field effect transistor in being contained in probe is amplified, whether be positioned at the driver's seat for detection of chaufeur, if chaufeur exists, then send a low level signal to micro controller system; If chaufeur does not exist, then send a high level signal to micro controller system.
Hall element adopts the ATS276 hall sensor, is installed on the automobile hand brake, for detection of the braking mode of parking brake, if be in braking state, then sends a high level signal to micro controller system; If be in not braking state, then send a low level signal to micro controller system.
Micro controller system adopts the STC89C52 micro controller system.This is a kind of low-power consumption, high-performance CMOS 8 8-digit microcontrollers, has 8K at system programmable Flash memory device.On single-chip, have dexterous 8 bit CPUs and Flash able to programme.Mainly for the treatment of sensor signal and control warning output.
Speech chip adopts the ISD25120 speech chip, this chip is the premium quality product of new generation that ISD company produces, have anti-outage, tonequality good, need not special-purpose characteristics such as voice development system, and can clean repeatedly, recording playback, information is forever preserved, and is easy to use.Record information of voice prompt in the speech chip in advance, when the improper use of chaufeur parking brake, as one sees fit it is carried out voice reminder.
Alarm unit comprises buzzer phone, AUTOMOTIVE RELAY and flasher, and described buzzer phone is connected with micro controller system respectively with AUTOMOTIVE RELAY, and described flasher is connected with AUTOMOTIVE RELAY.
When the work of this device, the detection signal of micro controller system receiving sensor judges whether whether parking brake uses correct, need to carry out alarm.Micro controller system judges that the situation of parking brake improper use has 3 kinds of combinations:
1) the vehicle switch signal is high level, and Hall element detects high level, and this moment, automobile was in opening, but parking brake is braking mode;
2) the vehicle switch signal is low level, and Hall element detects low level, and pyroelectric infrared sensor detects low level, and this moment, automobile was not opened, and chaufeur exists, and parking brake is braking not;
3) the vehicle switch signal is low level, and Hall element detects low level, and pyroelectric infrared sensor detects high level, and this moment, automobile was not opened, and chaufeur does not exist, and parking brake is braking not.
The improper use of micro controller system chaufeur parking brake is preceding 2 kinds of whens combination, and the control speech chip carries out voice suggestion, and the operation that makes chaufeur brake/unclamp parking brake according to voice suggestion is so that safe driving or parking; If when being judged as the 3rd kind of combination, then export a high level and give AUTOMOTIVE RELAY, allow the motor turning signal lamp glimmer, buzzer phone sends chimes of doom simultaneously, reminds chaufeur to note in time taking measures.
Used electronic devices and components are commercially available known product in the device of the present utility model, and those skilled in the art can realize the connection of each electronic devices and components according to the application's technique effect.
