Abstract
The utility model relates to a protection instrument for a vehicle, which comprises a keyboard circuit, a light-sensitive circuit, a press-key interrupting circuit, a CPU, an audio alarm circuit and a light coupling control circuit. A new generation CPU part is adopted to make the utility model has the advantages of enhancement of functions, improvement of reliability, simplification of hardware design and low cost. The utility model has the protection measures of the automatic conversion of far lamps and near lamps at the time of driving at night and cipher recognition; when a vehicle is illegally invaded, the utility model has the series measures of automatic power cut performance, fuel cut-off performance, alarms, nebulization, etc. to maintain the safety of drivers and the vehicle.
Description
The utility model belongs to vehicle security personnel field, particularly a kind of automotive security instrument.
Along with automobile quantity increases, the automotive safety problem becomes increasingly conspicuous.When two car nighttime meetinges, often because of far and near lamp conversion in time cause dazzling the eyes and jeopardize traffic safety, the incident that the stolen even chaufeur of automobile is subjected to grievous injury also happens occasionally, far away, low beam conversion of the prior art adopts simple photaesthesia electronic circuit to make controller, can't adapt to complicated situation, and existing thief-proof driving skills art product is not provided with far, the low beam automatic exchanger.Prior art also has following shortcoming: 1, the circuit complexity has hindered and has popularized; 2, pay attention to Vehicle anti-theft, and ignored the personal safety of chaufeur.
It is simple that the purpose of this utility model provides a kind of hardware, makes full use of software resource, volume is little, takes into account the automotive security instrument of night travel, meeting safety, anti-auto theft and chaufeur personal safety.
The automotive security instrument comprises that keyboard circuit, 2 groups of photosensitive circuits, 2 button junction circuits, CPU, audible alarm circuit, 3～8 groups of light corners close control circuit, the output of two groups of photosensitive circuits meets P30, the P33 of CPU respectively, and the output of keyboard circuit is connected with P1 mouth pin P20～P27 of CPU.CPU adopts GMS97L51, GMS97L52, GMS97C51 and GMS97C52, a kind of in 4 kinds of chips.
The utility model is owing to adopted the CPU that includes EPROM, make the I/O mouth of CPU can both provide the user to use, each I/O mouth line can drive a relay or high power transistor under application program management, the multi-mode operation when meeting surreptitiously to finish automobile, outage, oil-break, spraying, warning etc.Because the aforementioned techniques measure makes hardware design very simple, makes full use of software resource, volume is little, is suitable for batch manufacturing, is easy to generally promote.Utilize 8 electricity consumption branch roads of 8 difference Control of Automobile of P2 mouth, make auto theft person be difficult to succeed, therefore, chaufeur is met when robbing, and needn't worry automobile, can wait for an opportunity to withdraw, and guarantees that self escapes injury.
Fig. 1 is a composition frame chart of the present utility model.
Fig. 2 is the utility model schematic circuit diagram.
As shown in Figure 1, the utility model comprises CPU (1), 2 groups of photosensitive circuits (2), (3), keyboard circuit (4), 2 key junction circuits (5), (6), audible alarm circuit (7), control circuit (8), (9), (10), (11), (12), (13), (14), (15) are closed in the light corner.GR1, GR2 are photoconductive cell among Fig. 2, and coupled VT1, VT2 and 2 resistance are formed photosensitive circuit jointly.
Button S1, S2 among Fig. 2 promptly constituted aforementioned 2 key junction circuits (5), (6).
The light corner closes that control circuit closes device CNY17-1 by the light corner and transistor VT3, VT4, VT5 and relay constitute, and totally 8 groups of control circuits are closed in the light corner, and circuit is identical, only draws 1 group among Fig. 2, all the other omissions.
Circuit such as () Fig. 2 omitted power supply, crystal oscillator commonly used, reset as shown in Figure 2.Keyboard circuit links to each other with the P1 mouth 8 Tiaokou lines of CPU, wherein P10-P13 respectively is connected to 1 10K pull-up resistor, P14-P17 respectively connects keyboard by 1 diode, have 16 keys: 0,1,2,3 ... F, circuit all connects, energising back cpu reset also waits for that chaufeur inputs 8 figure place passwords by keyboard, behind the input password, CPU checks immediately, errorless as password, CPU will connect automobile igniting circuit etc. by I/O mouth control peripheral hardware, and chaufeur can be driven, wrong as the password input, CPU will cut off interlock circuit by relay, and the siren sound after 10 seconds of delaying time is after a period of time of delaying time again, CPU will cut off more electricity consumption branch road, and spraying (nuisanceless smog) is deterred the burglar.Safety with protection chaufeur and automobile.
The button junction circuit provides two kinds of manual type of alarms, and in a single day button S1 presses and will import interrupt signal by P32, and CPU will carry out alert program immediately.Button S2 presses by P34 input interrupt signal, and CPU postpones to carry out alert program after 600 seconds, and these two keys are according to circumstances applied in a flexible way by chaufeur.
In Fig. 2, what link to each other with P37 is audible alarm circuit, comprises 1 power discharging IC LM386, and alarm sound is to form with software simulation, through the P37 of CPU output, by sending loud speaker Y to send chimes of doom after the LM386 amplification.During night travel, send a car as the place ahead, GR1 is reduced by the place ahead light irradiation resistance far away immediately, VT1, the VT2 conducting, the VT2C electrode potential produces negative saltus step and sends interrupt signal by P33 to CPU, CPU responds interruption, carries out interrupt service routine and makes P20 become active potential by high potential, even relay J discharges, turn-off lamp far away, connect low beam, realize far away, low beam is changed automatically, after the time-delay several seconds, close low beam again, Kaiyuan City's lamp, and after CPU carries out interrupt service routine, reactionless temporarily to the light conditions that GR1 detects, at this moment CPU need pass through the GR2 detection front automobile illumination in the photosensitive circuit (2), record front automobile lamp far away as GR2 and do not close, then CPU can make lamp far away luminous in short-term by J, and the signal front automobile is closed lamp far away.
According to real case, and the automobile circuit complicated situation, the automotive security instrument should take variation to be connected with automobile circuit, makes that auto theft person is irregular to follow, and strengthens the result of use of automotive security instrument with this.
