Abstract
The utility model discloses a car parking braking indicator, comprising an integrated operational amplifier changing speed signals into digital signals; the output terminal of the integrated operational amplifier and the parking braking signal are respectively connected to the input terminal of a singlechip; the output terminal of the singlechip is connected with a sounder controlled by the singlechip. The high and low level signals produced by a parking brake being fastened and loosened and the signals from a speed sensor are sent to the circuit formed by the singlechip and judged and processed by the singlechip, which enable the sounder to produce sound alarm signals, indicating the driver to loosen the braking handle and thereby avoiding the damage to the vehicle brake block and the motor.
Description
Technical field
The utility model relates to the alarm set of brake system of car braking during standstill operation, belongs to electronic product.
Background technology
Present automobile generally all is equipped with parking brake indicator lamp (some vehicle is not installed this indicator lamp in early days), and its effect is: light during the tension braking during standstill, extinguish when loosening braking during standstill, note brake-applying handle with the prompting navigating mate.But because it only can provide the light caution, and be subjected to the circumscribed reason in installation site, and just can not play its due effect sometimes, make navigating mate in the situation down train of having forgotten to loosen Parking Brake, and cause braking brake pad wear, and driving engine is caused damage to automobile.
Summary of the invention
The purpose of this utility model is: provide a kind of and do not remind navigating mate to correct the automobile parking braking reminiscences of this mistake with the mode of audible alert when loosening Parking Brake behind running car.
The purpose of this utility model realizes by following scheme: described automobile parking braking reminiscences comprises the integrated operational amplifier that vehicle speed signal is transformed into digital signal, the mouth of integrated operational amplifier and parking brake signals are received respectively on the input pin of micro controller system, and the mouth of micro controller system is connected with by monolithic processor controlled sound-producing device.
As a kind of improvement, described sound-producing device comprises aerotron and the microphone device that drives microphone device.
As a kind of further improvement, described microphone device is loudspeaker or buzzer phone.
As a kind of further improvement, described microphone device is the voice integration module.
As a kind of further improvement, the mouth of described micro controller system also is connected with the light alarm set.
Owing to adopt above technical scheme, described automobile parking braking reminiscences comprises the integrated operational amplifier that vehicle speed signal is transformed into digital signal, the mouth of integrated operational amplifier and parking brake signals are received respectively on the input pin of micro controller system, and the mouth of micro controller system is connected with by monolithic processor controlled sound-producing device.With tension with loosen high and low level signal that Parking Brake produces and send in the circuit that constitutes by micro controller system from the signal of car speed sensor, after carrying out judgment processing by micro controller system, produce audible ringing signal by microphone device, thereby remind chaufeur loosen the brake handle, avoided the infringement that automobile brake brake facing and driving engine are caused.
Description of drawings
Accompanying drawing is the schematic diagram of the utility model embodiment.
The specific embodiment
As shown in drawings, a kind of automobile parking braking reminiscences comprises the integrated operational amplifier 4 that vehicle speed signal 2 is transformed into digital signal, the mouth of integrated operational amplifier 4 and parking brake signals 1 are received respectively on the input pin of micro controller system 5, and the mouth of micro controller system 5 is connected with the sound-producing device 6 by micro controller system 5 controls.Described sound-producing device 6 comprises aerotron 61 and the microphone device 62 that drives microphone device 62.Described microphone device 62 is loudspeaker or buzzer phone, also can adopt the voice integration module.
Perfect as a kind of technical scheme, the mouth of described micro controller system 5 also can reconnect the light alarm set.
Its principle of work is as follows: at first will be based on having on the automobile and the high and low level signal that switch produced of Parking Brake interlock and the signal (being generally impulse singla) of car speed sensor generation.If these two kinds or a certain equipment are not installed on the automobile, should be installed additional earlier.The signal that car speed sensor produces should meet the requirement of cmos digital circuit, if can not meet the demands, uses signal processing circuit and carries out the shaping processing.
With tension with loosen high and low level signal that Parking Brake produces and send in the circuit that constitutes by micro controller system from the signal of car speed sensor, carry out judgment processing by micro controller system after, produce audible ringing signal by microphone device.Situation one: if the level signal (for example high level) that Parking Brake produces is to loosen Parking Brake to produce, then no matter vehicle speed signal has (driving) not have (parking) does not all produce alarm sound; Situation two: Parking Brake produces if the level signal (for example low level) that Parking Brake produces is tension, do not produce alarm sound when then not having vehicle speed signal (parking), when being arranged, vehicle speed signal (driving) produces alarm sound, illustrate it is the driving of tension Parking Brake at this moment, remind navigating mate in time to loosen Parking Brake.After Parking Brake loosens, formation situation one, alarm sound stops immediately.
Characteristics of the present utility model are: only utilize signal that switch produced and the vehicle speed signal that links with Parking Brake, the processing of this product of process just can realize its purpose.And the automobile of producing later in general 2002 all has these two kinds of signals (even if do not have, installing additional also comparatively simple) basically.Therefore, no matter be automaker or vehicle maintenance and repair, decorate producer, installs all very simply, its installation site does not have specific (special) requirements yet, needs only in driving compartment.Particularly,, add this product, can increase a practical function as long as increase 4-6 bar wire harness for the automaker.
Description of drawings of the present utility model is as follows:
1---parking brake signals input end: high level (or low level) during the tension braking during standstill, low level when loosening braking during standstill (or high level).
2---the vehicle speed signal input end: pulse-free signal during parking has the consecutive pulses signal during driving.Also other can distinguish the signal that stops and drive a vehicle.
4---signal processing unit: generally compare device and come processing signals with integrated operational amplifier.Its effect is: 1, process the signal into the high-low level signal that meets the cmos digital circuit requirement; 2, signal 2 is processed into two kinds of different states.Therefore this circuit input impedance does not have influence to former car circuit substantially greater than a megaohm.
5---micro controller system: its effect is: the various combination to signal 1,2 carries out judgment processing, when tension Parking Brake and driving occurring, produces alerting signal, drives microphone device 62 and produces alarm sound.
62---microphone device: loudspeaker or buzzer phone.
R1, R2 are divider resistance, are connected on certain input end of integrated operational amplifier, as a comparison the reference voltage of signal.
C1, R3 are the reset circuit of micro controller system.
R4 is a current-limiting resistance, and T is for driving the middle low power aerotron of microphone device.
X, C2, C3 constitute the external crystal oscillating circuit of micro controller system internal oscillator.
