Simultaneously, a processing module U1 gets into state of dormancy when the automobile is flame -out totally, and it can be waken up by the 2nd processing module U2. The utility model discloses a take alarm clock to remind on -vehicle infotainment system of function sets up one of them processing module continuation work under the automobile flameout state through two processing module to according to its timing setting, can awaken another processing module up when reaching the settlement condition of regularly reminding, thereby reach the purpose that the alarm clock was reminded, and reduced quiescent current's influence.

Description

A kind of vehicle entertainment system with alarm clock calling function

Technical field

This utility model relates to vehicle-mounted multimedia equipment, particularly to a kind of vehicle entertainment system with alarm clock calling function.

Background technology

At present, vehicle audio entertainment systems is also more and more extensive in passenger car, commercial car and the application on engineering machinery vehicle, and the application of these vehicles is concentrated mainly on long-distance passenger transportation, shipping and in engineering project, it is characterized as being long-duration driving, or continuous operation, it is easy to produce fatigue driving.At clock display functionally, display screen is usually driven by driving chip by existing vehicle audio entertainment systems structure by uniprocessor, and alarm clock is then that utilize that processor calls on car outer puts equipment, realizes such as speaker etc..And equipment of putting outside these typically requires vehicle power and is powered, but it is under ACCOFF state at automobile ignition wire, namely when automobile stops working completely, clock cannot show, more can not play alarm clock calling function, and existing solution is that the power supply externally putting equipment and display screen changes into normal power supply source, but this can bring again the problem that quiescent current is excessive.

Summary of the invention

The purpose of this utility model is the defect in order to overcome above-mentioned background technology, it is provided that a kind of vehicle entertainment system with alarm clock calling function.

A kind of vehicle entertainment system with alarm clock calling function, including clock crystal oscillator, the first processing module, the second processing module and display screen, described first processing module includes connecting the clock end that is connected with described clock crystal oscillator of switch control terminal of automobile ignition wire and puts the signal output part that unit is connected and the first communication ends being connected with described second processing module with car outside；Second communication end that the display drive end that described second processing module includes being connected with described display screen is connected with described first processing module and timing module；Described timing module is connected with described automobile ignition wire, starts timing when automobile flameout；Described second processing module sends wake-up signal by described second communication end to described first processing module according to the signal of timing module.

Further, described first processing module also includes storing the storage module arranging parameter.

Further, described timing module also includes timing and arranges end.

Further, described display panel type is negative polarity LCDs

Vehicle entertainment system with alarm clock calling function of the present utility model, arranged by double; two processing modules, under automobile flameout state, one of them processing module works on, and arrange according to its timing, another processing module can be waken when imposing a condition up what reach timed reminding, thus reaching the purpose of alarm clock calling, and reduce the impact of quiescent current.

Accompanying drawing explanation

Fig. 1 is the system architecture schematic diagram in an embodiment of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, a kind of vehicle entertainment system with alarm clock calling function of the present utility model is further described.

A kind of vehicle entertainment system with alarm clock calling function, including clock crystal oscillator the 1, first processing module U1, the second processing module U2 and display screen 2.Being wherein the first processing module U1 output being realized clock signal by clock crystal oscillator 1 as reference, the second processing module U2 drives display screen 2 to display according to clock signal.Meanwhile, the first processing module U1 enters resting state when automobile is completely flame-out, and it can be waken up by the second processing module U2.

Concrete, the first processing module U1 includes switch control terminal CTRL, clock end signal CN, signal output part OUT, storage module 3 and the first communication ends DATA_1.Switch control terminal CTRL connects automobile ignition wire ACC, first processing module U1 obtains the different conditions of automobile ignition wire ACC by it, thus controlling the duty of the first processing module U1, when automobile ignition wire ACC is in completely flame-out, the first processing module U1 enters resting state.Clock end then connects clock crystal oscillator 1, obtains time signal accurately by the pulse signal of clock crystal oscillator 1.Signal output part OUT is then put unit 4 outside and is connected with car, such as speaker etc..For realizing alarm clock calling function.Further consisting in the second processing module U2 and carry out the mutual aspect of information, the first processing module U1 utilizes the first communication ends DATA_1 and the second processing module U2 to realize the mutual of information and instruction.Storage module 3 then for storing relevant configuration information, performs for the first processing module U1.

Second processing module U2 then includes display drive end DIR, second communication end DATA_2 and timing module 5.Wherein show that drive end DIR connects display screen 2, in the present embodiment, the display screen 2 realizing time showing can adopt digital LCD, when not wasting system resource, the second processing module U2 can to support the integrated process circuit unit that the 8Bit microprocessor that LCD segment encode drives is core component.It utilizes second communication end DATA_2 and the first processing module U1 to realize the mutual of information and instruction, and mainly transmission wakes instruction and temporal information up.The segment encode being mainly used in digital LCD when the first processing module U1 is in normal operation drives, it is achieved the display of digital dock.Another in conjunction with timing module 5, after the first processing module U1 enters resting state, start timing, simultaneously with timing module 5 for basis reference, continue to realize clock display.In timing module 5, it is connected with automobile ignition wire ACC, and for obtaining the power-up state of system, when automobile ignition wire ACC turns off, and the first processing module U1 enters resting state, it starts timing.

When current time meets alarm clock calling condition, timing module 5 notifies that the second processing module U2 sends wake-up signal to the first processing module U1.After second processing module U2 receives the instruction of timing module 5, send wake-up signal by second communication end DATA_2 to the first processing module U1 by second communication end DATA_2.Multimedia system is started shooting, and the first processing module U1 calls car puts unit 4 outside, it is achieved the function of alarm clock calling.Under preferable case, timing module 5 also includes timing and arranges end, and user can arrange the setting having held alarm clock by timing.

In preferred embodiment, in order to reduce the size of quiescent current, display screen 2 can adopt the LCDs of negative polarity.

Both relevant quiescent current parameter request be can have been met by above example, clock display and alarm clock calling function when automobile stops working completely realized again.

Above in conjunction with accompanying drawing, embodiment of the present utility model is explained in detail, but this utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, it is also possible to make various change under the premise without departing from this utility model objective.
