As shown in Figure 1, the disclosed intelligent lock car of the utility model pass window device mainly is made of microprocessor MCU, executive circuit, current sensor and power supply; A signal input part of microprocessor links to each other with the automobile ignition switch line, another signal input part of microprocessor links to each other with the automobile locking holding wire, and the another signal input part of microprocessor links to each other with the signal output part of current sensor in being connected on vehicle dormer window and Car window electric machine current supply circuit; The signal output part of microprocessor rises window/link to each other with relay coil that the skylight disable motor opens/stops with the Control of Automobile vehicle window respectively by executive circuit, and control rises opening/stopping of window motor, thus the pass window of Control of Automobile.

After automobile engine was extinguished, when promptly the automobile ignition switch line was the OFF state, the utility model microprocessor was in wait state; When the car owner sent vehicle-locking signal, when promptly the automobile locking holding wire was the ON state, microprocessor was started working; Signal output part output control signal of microprocessor by executive circuit, makes a car door of automobile rise the window motor and starts working, rises window; After this glass for vehicle window was raised to the top, time-delay a period of time, microprocessor began to export next control signal, made the next car door of automobile rise the window motor and started working, rises window; After this glass for vehicle window was raised to the top, time-delay a period of time, microprocessor was exported next control signal again, made another car door of automobile rise the window motor and started working, rises window; So move in circles, microprocessor is exported control signal successively, make four car door vehicle windows of automobile/and the skylight close successively.In rising window machine operation process, in case vehicle window is raised to the top, after liter window motor is stuck, the electric current that rises in the window motor current supply circuit raises, the current sensor senses that is connected in the motor current supply circuit is after vehicle window has been raised to the top to this situation, microprocessor cuts off this road immediately and rises the window motor control signal, makes this road rise the window motor and quits work, to prevent that rising the window motor is burnt because of long-time locked rotor current raises.

Fig. 2 is the utility model physical circuit figure.As shown in the figure, mainly (seven NPN darlington transistor array U4, triode T1～T4, resistance R 13～R20), current sensor H1 and power supply U2 (5V voltage stabilizing chip 78L05) constitute the utility model by microprocessor U3 (model PIC16C505), executive circuit.

The working signal end pin 3 of forbidding of microprocessor U3 links to each other with the automobile ignition switch line by socket A3.After automobile engine was flame-out, the pin 3 of U3 was a low level, and microprocessor U3 is in wait state; When automobile engine was worked, the pin 3 of U3 was a high level, and microprocessor U3 is in and forbids duty, prevented in vehicle traveling process, occurred because automatic blocking causes the maloperation of automatic pass window.

Another signal input part of microprocessor is that the pin 5 or 6 of the utility model enabling signal control end U3 links to each other with the automobile locking holding wire by toggle switch X1, socket A4.If the vehicle-locking signal that the car owner sends is a positive pulse signal, 1,3 conductings of toggle switch X1, the pin 6 of U3 is a high level, microprocessor U3 starts working; If the vehicle-locking signal that the car owner sends is a undersuing, 1,2 conductings of toggle switch X1, the pin 5 of U3 is a low level, microprocessor U3 starts working.

After the microprocessor U3 work, the pin one 3 output high level of U3 drive relay J 1 coil through Darlington transistor U4 and make normal battle closed, and it is charged to make automobile electric car-window, skylight rise window motor current supply circuit.

Six road signal output part pin ones 2,11,10,9,8,7 of microprocessor U3 are exported high level successively, by seven darlington transistor array U4, drive lifting relay rising control coil negative pole and skylight oblique deascension, the sliding control end negative pole that closes successively; If former car lifting relay rising control coil is anodal control, then toggle switch X2, X3, X4, X5 connect 1,3 positions, make triode T4, T3, T2, T1 conducting in the executive circuit, power to relay coil, again referring to Fig. 3, what so just can drive that former car is equipped with rises anodal control of window relay or negative pole control (skylight is negative pole control), makes to rise the charged adhesive of relay coil that the window motor opens/stops, make the controlled charged rotation of window motor that rises, rise window.The utility model microprocessor U3 exports control signal successively, make and rise the rotation of window motor, that is to say, each microprocessor is only exported a control signal, make one to rise the window machine operation, after having only a vehicle window to be raised to the top, microprocessor is just exported another control signal, makes another rise the window machine operation.

In rising window machine operation process, in case vehicle window is raised to the top, after liter window motor is stuck, being connected on current sensor H1 in the motor current supply circuit, to detect this situation be after vehicle window has been raised to the top, the state of the microprocessor U3 that links to each other with the signal output part of current sensor H1 judges that pin 4 is high level, U3 cuts off this road immediately and rises the window motor control signal, makes this road rise the window motor and quits work, to prevent that rising the window motor is burnt because of long-time locked rotor current raises.In running, microprocessor U3 judges once that every 20mS if current sensor H1 output low level, microprocessor U3 allows this road to rise the window machine operation, if current sensor H1 output high level, microprocessor U3 cuts off this road output immediately.

In specific embodiment of the utility model, the 7th pin of microprocessor U3 closes window Electric Machine Control end with the slip of controlled skylight and links to each other; The 8th pin closes window Electric Machine Control end with the oblique deascension of controlled skylight and links to each other; The 9th pin rises window Electric Machine Control end with controlled right front door and links to each other; The 10th pin rises window Electric Machine Control end with controlled right back door and links to each other; The 11st pin rises window Electric Machine Control end with controlled left back door and links to each other; The controlled left front door of the 12nd pin rises window Electric Machine Control end and links to each other.

Workflow of the present invention is: four power windows of automobile and power sunroof rise the window motor divides and works one by one sequentially for six times, each vehicle window and skylight close finish the back at interval 300mS start next vehicle window and rise the window motor.Simultaneously, microprocessor U3 when detecting it for high level, makes any one output pin of working become low level every the level state of 20mS judgement primary current sensor output rapidly, cuts off the power supply that rises the window motor, and it is stopped the rotation.

Concrete workflow: when the 3rd pin of microprocessor U3 is in low level state, when its 5th pin is subjected to a negative pulse or the 6th pin and is subjected to a positive pulse, the 13rd pin of U3 becomes high level by low level, and automotive window and skylight rise the conducting of window motor current supply circuit, power supply.After microprocessor postpones 300mS, the 12nd pin becomes high level by low level, make the right front door of automobile rise the window machine operation, close window through executive circuit, behind the time-delay 10s, be after vehicle window is raised to the top, the 12nd pin of microprocessor U3 becomes low level again by high level, rise the window motor side, stop the rotation, in rising the 10s clock of window machine operation, U3 is every the 4th pin (judgement pin) of a U3 of 20mS detection, when the 4th pin becomes high level by low level, U3 becomes low level with the 12nd pin of U3 by high level immediately, cuts off this road output.Microprocessor U3 postpones 300mS, and the 11st pin of U3 becomes high level by low level, starts right back door and rises the window motor, and its course of work is identical with above-mentioned the 12nd pin.After right back door pass window finished, microprocessor U3 postponed 300mS, and its 10th pin becomes high level by low level, started left back door and rose the window motor, closes window, and its course of work is identical with above-mentioned the 12nd pin.So circulation is one time, four car door vehicle windows of automobile and skylight is closed finish.

The selected current sensor of the utility model mainly contains hall device (H1) SJ411, integrated transporting discharging (U1) TL072 and forms, SJ411 is a linear current detection means, characteristics be can realize electrical isolation, be detected big electric current and the isolation between the induced signal, and the small-signal and the detected big electric current of output are proportional.Wherein, the typical differential operational amplification circuit of forming by U1A and R5, R6, R7, R21, the voltage comparator of forming by U1B, W1, the reverse input end of U1B (5 pin) is adjusted to a reference voltage through W1, this voltage is set in the output voltage values of electric current that H1 senses U1A when reaching 13A, the load current that 5A～7A is arranged during the lifting motor operate as normal approximately, the electrical signal of reaction that this moment, H1 produced is very small, after differential amplifier amplifies, output voltage is still well below the threshold voltage of U1B, 7 pin of U1B still are low level output, control circuit operate as normal; When vehicle window is raised to the summit, lifting motor is stuck, electric motor loop electric current rise rapidly (more than the 15A), when surpassing 13A, the output voltage of U1A rises rapidly, surpass the U1B threshold voltage, output pin (7 pin) upset is high level, through 4th pin (judgement pin) of R12 to U3, make U3 finish the control loop of working in advance, stuck lifting motor loop open circuit, to arrive 0A under the induced-current at H1 place is rapid, current sensor output pin (7 pin) upset is low level, guarantees to carry out next door and window lifting motor and works.But adjust the threshold voltage of W1 setting voltage comparator, to set with size to the protective current initial value.

The hall device (SJ411) that constitutes current sensor also can replace with a sample resistance, resistance value is 0.02 ohm, allow electric current 20A, differential amplifier circuit is constant, by adjusting the resistance of R5, R6, R7, R21, also can play the identical effect with SJ411, the advantage of doing like this is to reduce cost; Shortcoming is to realize the electrical equipment isolation.

Fig. 3 is the wiring graph of a relation of the utility model lead-out terminal.As shown in the figure, wherein, lead-out terminal B11 links to each other with the automobile electric car-window current supply circuit, and lead-out terminal B12 links to each other with the automotive power sunroof current supply circuit, and lead-out terminal B1～B4 links to each other with the window Electric Machine Control end that rises of four power windows about automobile is forward and backward respectively; Lead-out terminal B5, B6 slide with automotive power sunroof respectively and close window, oblique pass window Electric Machine Control end links to each other.

In existing motorcar electric window and door system, the method that the control of hand-operated lifting switch rises the window motor has two kinds: a kind of is to rise the relay positive pole that the window motor opens/stops by control control; Another kind is to rise the relay negative pole that the window motor opens/stops by control control.As shown in Figure 2, when running into direction switch control relay positive pole that the wire jumper 1,2 of toggle switch X2, X3, X4, X5 is continuous, make T4, T3, T2, T1 rise the power supply of window relay to four respectively by B1, B2, B3, B4; When running into direction switch control relay negative pole, the wire jumper 1,3 of toggle switch X2, X3, X4, X5 is linked to each other, make the 15th pin, the 14th pin, the 13rd pin, the 12nd pin of U4 directly make four to rise the conducting over the ground of window relay respectively, so the present invention can compatible all kinds of power window control circuits by B1, B2, B3, B4.

Just at present car power window circuit system can be divided into two big classes, wherein a class as shown in Figure 3 direction switch and then control and rise the window motor by control relay.Mode, application that another kind of traditional as shown in Figure 4 direction switch is directly controlled lifting motor are also very extensive, such as the mulberry tower sodium series of germany volkswagen company in China's Mainland production; The Buick series that AM General company produces in Chinese Shanghai still adopts this mode, the market of this class vehicle is also very huge, compatible this class vehicle of the present invention's energy, increase by one 5 pin relays at output executing circuit, replace the above-mentioned window relay that rises to realize automatic lifting windows control, figure four is connection layouts of one of them door and window control circuit in four power windows, direction switch at former car equipment is connected in series one 5 pin relays to lifting motor rising control circuit, wherein a normally closed fixed contact connects direction switch, one normally closed armature contact connects lifting motor, the A point of constant open contact in Fig. 2 connects current sensor to positive 12V power supply, the positive 12V power supply of coil one termination, the other end directly connects the output of U4 of the present invention (ULN2003) (with reference to Fig. 2 U4 the 15th, 14,13,12 pin, T4, T3, T2, T1 remove need not), its operating principle is (with reference to Fig. 4): when windowing with hand switch or closing window, because the closure of relay constant close contact, the electric motor loop conducting does not influence machine operation.When the lock car rises window, ULN2003 drives relay work opens normally closed armature contact, the constant open contact closure, electric current by positive source through current sensor, relay, lifting motor, direction switch to power cathode, motor rotates to the vehicle window ascent direction, when glass for vehicle window rises to the summit, current sensor sends shutdown signal, make stuck lifting motor cut off the power supply rapidly (method with noted earlier have the method that rises the window control relay circuit identical), start next road lifting motor work then, so just realized that the lock car closes window automatically.

The above only is preferred embodiment of the present utility model, and protection domain of the present utility model is not limited thereto.Anyly all belong within the utility model protection domain based on the equivalent transformation on the technical solutions of the utility model.
