Abstract
The utility model discloses an intelligent on-off prompting device of an automobile handbrake. The intelligent on-off prompting device comprises a pressure sensor, a photoelectric sensor and a buzzer, wherein the pressure sensor is installed on a clutch pedal; the photoelectric sensor is installed at two sides of the handbrake; the pressure sensor, the photoelectric sensor and the buzzer are connected with a singlechip respectively; and the singlechip is further in signal connection with an ignition switch. The intelligent on-off prompting device is simple in structure, easy to realize and capable of prompting a driver to loosen the handbrake in time, so that the corrosion to the mechanical transmission part of the automobile is reduced; and the intelligent on-off prompting device has a certain instruction meaning for standard operation of the driver.
Description
Technical field
The utility model belongs to the process control field, relates to the auxiliary device of vehicle, is specifically related to a kind of vehicle parking brake intelligence and opens and closes alarm set.
Background technology
Braking during standstill generally is called parking brake, and its effect is exactly when stopping, and gives resistance of automobile, makes automobile not slip car.Just parking brake pins transmission shaft or trailing wheel.Braking during standstill is little more a lot of than the power of service brake, only is that do not slip car when stopping on road, sloping road just passable.Almost all be furnished with parking brake on each automobile now, parking brake has become one of requisite stopping brake instrument of present automobile.Though nowadays most of automobiles all have the parking brake pull-up or remove warning light on gauge panel; But most of chaufeurs particularly the chaufeur of new hand's steering vehicle often take the eyes off the gauges the dish in addition the gauge panel of failing to understand; Therefore forget pull-up or remove parking brake that the lighter can make a mess of parking brake through regular meeting, weight person can cause traffic accident; Make damaged vehicle, harm people's life security.Therefore, necessary pull-up or releasing to parking brake reminded, thereby both protected hand brake device, avoided traffic accident again, protected the life security of chaufeur.
Summary of the invention
To defective of the prior art or deficiency, the purpose of the utility model is, provides a kind of vehicle parking brake intelligence to open and close alarm set.
For realizing above-mentioned technical assignment, the utility model is taked following technical solution:
A kind of vehicle parking brake intelligence opens and closes alarm set; It is characterized in that; Comprise and pressure sensor that is installed on the pedal of clutch and the opto-electronic pickup that is installed in both sides on the parking brake also have a buzzer phone, pressure sensor, opto-electronic pickup; Buzzer phone is connected with a micro controller system respectively, and micro controller system also is connected with the ignition lock signal.
Other characteristics of the utility model are:
Said pressure sensor is selected the HK-610G pressure sensor.
Said opto-electronic pickup is selected the PT-A photoelectric switch.
Said micro controller system adopts the MC9S12XS128 micro controller system.
The utility model vehicle parking brake intelligence opens and closes alarm set, and is simple in structure, realizes easily, is easy to realize, can remind chaufeur in time to unclamp parking brake in advance, reduces the wearing and tearing to the vehicle mechanical running part, and the chaufeur standard operation is had certain directive significance.
Description of drawings
Fig. 1 is that the vehicle parking brake intelligence of the utility model opens and closes the alarm set structured flowchart.
Fig. 2 is the position view of opto-electronic pickup at parking brake.Being labeled as among the figure: 1, parking brake, 2, opto-electronic pickup, 3, light beam hole.
Below in conjunction with the specific embodiment the utility model is done further to explain.
The specific embodiment
Referring to Fig. 1, present embodiment provides a kind of vehicle parking brake intelligence and opens and closes alarm set, comprises the pressure sensor that is installed on the pedal of clutch, is installed in the opto-electronic pickup on the parking brake, and ignition lock signal and buzzer phone, and they link to each other with micro controller system respectively.
Referring to Fig. 2, opto-electronic pickup 2 is positioned at parking brake 1 both sides, makes light beam hole 3 symmetries on the opto-electronic pickup 2, when parking brake 1 pull-up, and light beam hole 3 light-permeables, when parking brake 1 was removed, light beam hole 3 was blocked.
In the present embodiment, pressure sensor is selected the HK-610G pressure sensor, and opto-electronic pickup is selected the PT-A photoelectric switch, and micro controller system adopts the MC9S12XS128 micro controller system, and above-mentioned each components and parts are supplied power by Vehicular accumulator cell.Its cardinal principle is; By the ignition lock signal; Pressure sensor signal judges that automobile is in starting state or halted state; Judge parking brake pull-up or disarm state by opto-electronic pickup, whether micro controller system works according to ignition lock signal, pressure sensor signal and photo-sensor signal will control buzzer phone.
(1) open ignition lock, the ignition lock signal is imported micro controller system, is contained in the variation of the pressure sensor detection clutch-pedal pressure on the pedal of clutch; Along with chaufeur slowly lifts pedal of clutch, the pressure of pedal of clutch reduces gradually, explains that chaufeur will start vehicle; The pull-up of opto-electronic pickup judgement this moment parking brake is still removed, and photoelectric switch breaks off if parking brake is not removed then, at this moment; Micro controller system judges that according to closing the signal that the electric switch transmission returns parking brake opens and closes situation, when photoelectric switch breaks off, explains that parking brake do not remove; At this moment, the Single-chip Controlling buzzer phone reminds chaufeur to remove parking brake; If parking brake is removed, photoelectric switch is closed, explain that chaufeur removed parking brake, and buzzer phone is not worked at this moment.Can guarantee that parking brake does not start preceding releasing at vehicle by actv. like this, can reduce damage the vehicle mechanical running part.
(2) close ignition lock.When vehicle stopped, ignition lock was closed, at this moment, and ignition lock signal input micro controller system; Micro controller system judges this moment whether parking brake is pulled on, if do not pull the hand brake, then photoelectric switch breaks off, and this moment, the Single-chip Controlling buzzer phone was not worked; Forget when pulling the hand brake that when chaufeur photoelectric switch is connected, explain that chaufeur do not pull on parking brake as yet; At this moment, the Single-chip Controlling buzzer phone sends alarm signal, reminds chaufeur to pull on parking brake.
Claims (4)
