Description
Technical field
The present invention relates to a kind of vehicle control syetem controlling Intelligent video equipment；It passes through vehicle-mounted home control mould
Block connects mobile Internet, mutual with intelligent household control terminal, completes the management function of home equipment, and it belongs to
A kind of at vehicle-mounted Internet of Things, inter-vehicle information system.
Background technology
Along with the people's continuous pursuit to quality of the life, the requirement enjoyed for home audio-visual is more and more higher, sound equipment
The crowd of fan rises the most year by year.In numerous audio-visual devices, as a example by " courage machine ", at fever sound equipment circle courage
Machine this seem old out-of-date equipment and but enjoy high praise, deeply liked by a lot of Fanciers, why courage machine
Have the status so do not replaced？First we look at that what is " courage machine ".
So-called " courage machine " i.e. discharge-tube amplifier being commonly called as at sound equipment circle.1904, first electron tube in the world
In the Fleming's subordinate birth of English physicist.Fleming obtains the patent right of this invention for this.The mankind
The birth of first electron tube, indicates that the world is thence into electronic age.First computer is with 1.8 in the world
Ten thousand electron tubes, take up an area 170m*2, weight 30t, power consumption 150kW.
Electron tube shortcoming is a lot, such as volume is big, power consumption big, heating severity, the life-span short (the most thousand of hours),
Power utilization efficiency is low, fragile structure, need high voltage power supply and distortion is high.The comprehensive distortion of discharge-tube amplifier refers to
Number THD is generally up to 2%-4%.After transistor produces, owing to " volume is little, power consumptive province " the most just instead of electricity
Son pipe, the progress of technology, cause electron tube to move towards to decay from prosperity.The most it is eliminated at most fields, but
Music Appreciation field is still enlivened, and why this is？
Originally electron tube machine is up to the distorted portion of 2%-4%, mainly even-order harmonic distortion, and these are abundant just
Even-order harmonic is added in audio signal so that it is sounds and feels mellow melodious.And although transistor machine THD can accomplish very
Low, the such as 0.1% even lower high-fidelity that can be described as, but transistor self cannot produce even-order harmonic, Er Qieqi
Subharmonic is higher than electron tube.For from sense of hearing, human ear is more sensitive to odd harmonic distortion, subjective can feel
Stiff, repel；But even-order harmonic distortion is milder to the sensation of people then ratio, and human ear is acceptant, another example is same
Sample explanation this point: the tone color that piano is charming, also in that sound of musical instrument contains abundant even-order harmonic.
Although visible for the technical indicators such as distortion, transistor is better than electron tube, but the distortion of electron tube belongs to
Even ripple, so good with its audibility at audio area electron tube, sound is mellow and full and obtains liking of numerous people.
Also become and music higher pursuit personage is pursued.The such as electron tube power amplifier in high-end field, microphone
Amplifier etc., is all extremely to praise highly with warm soft sound characteristics.
But due to the operation principle of electron tube self, its shortcoming existed also can not be ignored.One piece heated
Metallic plate, when its temperature reaches more than 800 degree Celsius, can form the accelerated motion of electronics, so that can break away from
Metallic plate itself escapes into the space beyond metal surface to their attraction.If in this space plus one ten
(trace of the walking in the snow picture tube arrived said above, just added with 7000--27000 on anode for the forward voltage of several to several ten thousand volts
The high pressure of volt), these electronics will be attracted and fly to forward voltage pole, flow through power supply and form loop current.Electricity
When the work of sub-pipe is to need cathodic metal plate to reach uniform temperature, electron emission state could be good.
Being based on this principle, the work of courage machine is necessary for preheating, and only carries out the preheating of a period of time and just may be used
To reach good working effect.Generally courage machine is preheating to optimum state at least needs 30 minutes, some needs 1 hour.
But when people need to listen music, often have little time preheating of starting shooting in advance, and if etc. get home music to be listened when the most pre-
Heat, needs again to wait for a long time.At home it can be seen that fan's complaint to this problem in some sound equipment forums.
Such as: " when that courage machine just being started shooting, sound is tangible the most how, and after 20 minutes, sound just starts to rise the best
Come, the when that sound going on the right way by the time, through 1 hour.The first symphony of Beethovan one is also drilled and is over.And this
In sound the most just！So, though this Dong Dong fivebyfive of courage machine, it starts too late.”
" after starting shooting 2 hours, state is basicly stable, and sound also has the biggest change (pleasing to the ear and resistance to listen), but recently
Work overtime every day 8 and go home, listen half an hour to be necessary for sleep after being preheating to state, be really intended to solve this lance
Shield.”
Some users first notify before even going home that household starts shooting preheating, and waiting has got home listens again.Visible courage machine this
The problem needing preheating is the most universal and anxious to be resolved.But for people unmanned in family and that every day is the most on and off duty
For, allow household help start the most unpractical.
Moreover, a lot of transistor power amplifiers equally need preheating in fact, here it is the most a lot of American blend
Cd decoding and prime do not have power switch, and if you remove to see their specification, producer can advise that you lead to the most forever
Electricity, does not shut down.
But along with the rise of technology of Internet of things, the remote control of household is become feasible.In recent years, automobile bond
Networking causes extensive concern as a kind of new direction in intelligent transportation field.Along with consumer to vehicle safety,
Comfort type, intellectuality, networking require improve constantly, the development of Hyundai Motor electronics by computer, communication,
Microelectronics, sensor, network technology incorporate in entire vehicle design, make automobile by traditional engineering goods to machine
Electrical integrated new high-tech product develops.
In following development, automobile will be no longer isolated unit, but becomes the network node of movement；Vehicle-mounted
Control system, as the important component part of vehicle electronics, uses the skills such as CPU, satellite fix, communication, control
Art provides safe and environment-friendly and comfortableness function for driver；As the part of intelligent automobile, vehicle-mounted control
System includes automobile computer, Intelligent navigator, drive recorder, in-vehicle multi-media system etc. from hardware.Car
Borne control system may be constructed independent network in car, it is also possible to becomes a net by connecting mobile Internet
Network node, it is achieved more networks function, in terms of computer realm, vehicle control syetem is that the calculating of a movement is put down
Platform.
Preheat although existing Intelligent video vehicle control syetem can realize remote opening courage machine.But household electrical appliances are set
Standby when being controlled starting device work, often at audio-visual devices once receiving after control instruction switches on power immediately
Open work.But every day comes off duty, road conditions is all not quite similar, and the road conditions on road be change unpredictably,
There are the various factors of instability, including congestion in road or that the road is clear is without hindrance；Particularly, in next peak period
Be frequently encountered by the most serious situation of blocking up especially, or be out of order etc. temporarily emergency case time cause interim traffic congestion,
Then get home the time and the startup time is not one and stablizes constant.When at present courage machine remotely being controlled, due to
When starting courage machine, how long the preheating parameter such as lacks accurate optimization.This is it is possible to cause the start preheating of courage machine
Too early, user does not also get home, and causes energy waste, and courage organic electronic tube lifetime shortens.It is also possible to the start of courage machine pre-
Too late, user to family is not preheating to perfect condition to heat yet, experiences to the appreciation of user and impacts.
There are problems in visible current vehicle-mounted house control system:
1, preheating courage machine control instruction sends the time and there is deviation the actual time of getting home, causes courage machine long for preheating time,
Energy waste, shortens the courage machine life-span.Or preheating time is too short, user to family is also not reaching to perfect condition.
2, navigation information shows at console, and driver needs to shift sight, causes driving danger.
3, control button is at console, and driver needs to shift sight, causes driving danger.
4, GPS tests the speed and itself there is error, and GPS terminal machine can receive the radio wave from 4 satellites, solve
Quaternary Nonlinear System of Equations just can determine that the locus of vehicle.Use the method can record terminating machine (mobile phone) to exist
Two space coordinates of 5s time starting point, so that it is determined that the displacement within the 5s time, then draw travel speed.
Due to range finding time delay, climate change and the impact of terrestrial magnetism, there is error in GPS positioning precision, if satellite clock
With user clock error 10ns, be then equivalent to pseudorange error 3m.GPS distance range rate error is relatively big, error rate
Up to more than 4%.
5, gps signal is unstable, weak or enter the situation in tunnel when running into signal, it is impossible to obtain real-time speed, make
Anticipated time Estimate of getting home is become to be forbidden.
6, the navigation anticipated time of getting home is forbidden, and the actual time of getting home is often very big with the relation of road conditions, traditional optimization
Method is to combine electronic chart real-time road to select optimal route, but, electronic chart can only obtain current road conditions,
And road conditions can change when driving, the most precalculated anticipated time of getting home is not accurate enough.
Visible, prior art still exists a lot of needs and optimizes and the problem of improvement.

Detailed description of the invention
Along with the rise of technology of Internet of things, the intelligence degree of home appliance is more and more higher, i.e. intelligent appliance equipment will
Being the trend of future development, current intelligent appliance equipment is typically by the screen of the terminal device such as mobile phone, panel computer
Operation realizes subscriber terminal equipment and remotely controls.The present invention proposes a kind of can remotely control the vehicle-mounted of sound equipment courage machine
Control system, and problem present in existing vehicle control syetem is optimized, improve and sound equipment courage machine is started
The accuracy of time estimation, improves manipulation convenience and the security of vehicle control syetem, brings not for user
The same long-distance intelligent preheating is experienced.
Below in conjunction with the drawings and the specific embodiments, the present invention is further described.
As shown in Figure 2, the present invention provides a kind of vehicle control syetem controlling Intelligent video equipment,
Including: wireless communication module: include GSM, one of GPRS, 3G/4G, WIFI or a combination thereof；
GPS module: obtain user current location and map traffic information, by navigation way road conditions segmentation according to the map,
When calculating each section estimated time of passing and estimate to get home；
Travelling data acquisition module: include CAN interface, is connected the real-time speed of acquisition with automobile CAN-bus,
Obtain the actual of current road segment and pass through the time；
Calibration module: compare GPS module and the data of travelling data acquisition module, when current road segment actual passes through
Between carry out ratio calculation with anticipated meter by the time, obtain difference FACTOR P；
Preheating electrical control module: containing controlling the various instructions of sound equipment courage machine, to preheating time of sound equipment courage machine and pre-
The setting of heat pattern；
Described processor, receives the P value of anticipated get home time and the travelling data acquisition module of described GPS module,
Estimate after calculating calibration to get home the time, after the preheating time be given further according to sound equipment courage machine control module, with calibration
The anticipated time of getting home compares, and sends warm-up control according to comparative result by wireless communication module and instructs.
Prior art relies on GPS map traffic information calculate anticipated getting home the time, and actual road conditions are not under steam
Disconnected change, the deviation of GPS map road conditions and actual road conditions certainly exists, it is contemplated that the problem that the time of getting home is forbidden is difficult to
Overcome.
On the other hand, GPS tests the speed and itself there is deviation, due to range finding time delay, climate change and the impact of terrestrial magnetism,
There is error in GPS positioning precision, if satellite clock and user clock error 10ns, is then equivalent to pseudorange error 3m.
As a example by the speed of automobile 100km/h travels.3min distance travelled reaches 5000m.When highway plane line style
During for circular curve, motorcycle travels on arc highway, and GPS mensuration is car speed of straight-line travelling on string.
Running car is 420m at radius, when central angle is the circular curve highway of 60 °, when actual travel mileage 439.6
During m, the distance travelled of GPS range finding is 420m, and error is 19.6m, and error rate reaches 4.5%.If by this circular arc
The shape section time is 20s, then actual vehicle speed be the speed that 79.1km/h, GPS record be 75.6km/h, less than real
Border speed 3.5km/h, error rate is positive 4.4%.
Visible GPS tests the speed and itself there is error rate, and GPS map road conditions there is also error's composition error will be bigger,
Accurately the estimation time of getting home is difficult to.
The advantage using such scheme is, the present invention utilizes the CAN interface of travelling data acquisition module directly to obtain
Take the actual speed of running car, GPS tested the speed and estimates that the time of getting home calibrates, it is thus achieved that estimating the most accurately
Get home time value.Concrete grammar is, utilizes the CAN interface of travelling data acquisition module directly to obtain running car
Actual speed, obtain the actual of current road segment and pass through the time.The actual of current road segment is passed through by described calibration module
The anticipated meter that time and GPS module are given carries out ratio calculation by the time, obtains difference FACTOR P.By difference FACTOR P
It is multiplied with each section estimated time of passing, estimates to get home after obtaining calibrating follow-up each section estimated time of passing and calibration
Time.Computing formula is:
P=current road segment is actual by time/current road segment estimated time of passing
The anticipated time * P that gets home that gets home the time=estimate after calibration
Owing to each section on travel route has continuity, situation about getting congestion the most also have continuity and
Tendency, if current road segment jam situation and GPS map road conditions have deviation, then the reality of subsequent section in certain journey
Also deviation can be there is with GPS map road conditions in road conditions, therefore by the difference system of deviation between current road segment and GPS map road conditions
Number P substitutes into the anticipated of subsequent section and gets home the time so that estimate that the accuracy of time of getting home is greatly improved.
The another advantage using such scheme is, except the calibration of error to GPS own, collecting vehicle information mould
Block can also make up the deficiency of GPS module, when gps signal is unstable or vehicle does not has gps signal when sailing tunnel into, and can
The anticipated time of getting home is calibrated by the CAN interface continuation real-time speed of acquisition.
Further, also include by wireless communication module, the duty of sound equipment courage machine is fed back to user.
Advantage is, utilizes communication module can realize the feedback of information, it is simple to solve preheating situation in user is real-time family.
Further, preheating electrical control module was estimated to get home the time after calibration according to the preheating time of preheating electrical equipment,
Direct or prompting user sends pipeline start up by preheating instruction, including 3 kinds of patterns, is described separately these three pattern below.
(1) when anticipated after described calibration get home the time less than or equal to preheating time of sound equipment courage machine time, directly or carry
Show that user issues pipeline start up by preheating by wireless communication module and instructs.
This mode feature is that sound equipment courage machine starts in time, and shortcoming is to be likely to be due to after current road segment road conditions are much better than
Continuous section, vehicle is the highest in a certain section speed, starts preheating electrical equipment according to an instantaneous value, if subsequent section road conditions
Change, easily cause the situation that user when having preheated still does not gets home.
(2) when anticipated after described calibration get home the time less than or equal to preheating time of sound equipment courage machine time, carry out credible
Degree is analyzed, and gets home the preheating time less than or equal to the sound equipment courage machine time, the most directly if anticipated after described calibration after N minute
Connect or point out user to instruct by issuing pipeline start up by preheating；If after described calibration, the anticipated time of getting home is more than sound after N minute
Ring the preheating time of courage machine, the most do not carry out any operation.
The feature of this pattern is, when the time of getting home anticipated after vehicle alignment in a transient state less than or equal to sound equipment courage machine
Preheating time time, start sound equipment courage machine the most immediately, and be by the Analysis on confidence of a period of time, concrete grammar
Be after the calibration after verification N minute the anticipated time of getting home the most still less than or equal to the preheating time of sound equipment courage machine.If N
After calibration after minute, the anticipated time of getting home still then thinks credible, the most directly less than or equal to sound equipment courage machine preheating time
Or prompting user issues pipeline start up by preheating instruction.If the anticipated time of getting home is pre-more than sound equipment courage machine after the calibration after N minute
The heat time, then illustrate that situation just now is insincere, be owing in route, a certain section road conditions are much better than other sections,
Too fast at a certain non-intersection speed so that after being calibrated by this section, anticipated time transients value of getting home is less than or equal to sound
Ring courage machine preheating time, and subsequent section is blocked up seriously, estimates that the time of getting home is the biggest after subsequent section after calibration
Preheating time in sound equipment courage machine.The most do not start intelligence courage machine.Have an advantage in that, be substantially reduced preheating electrical equipment
Start too early, preheat the appearance of excessive situation；Disadvantageously, N is excessive, easily causing startup too late, N is too small then
Easily cause inspection invalid, it sometimes appear that meal of getting home the most is not preheating to the situation of perfect condition.
(3) when anticipated after described calibration get home the time less than or equal to+N minute preheating time of sound equipment courage machine time, enter
Row Analysis on confidence, gets home the preheating time less than or equal to the sound equipment courage machine time if anticipated after described calibration after N minute,
Then direct or prompting user instructs by issuing pipeline start up by preheating；If after described calibration, the anticipated time of getting home is big after N minute
The preheating time of sound equipment courage machine, repeat the above steps the most again.
The feature of this pattern is, by preposition for the Check-Out Time of pattern (2), combines pattern (1) and (2)
Advantage, in the case of ensureing as far as possible to start in time, carried out again Analysis on confidence, be in these three pattern
Good one.
Choosing for N, can have two ways, one is the optional N of fixed value in the range of 1-5 minute, excellent
Select 3 minutes.Another kind is the change model of time value of repeatedly being got home by (such as one week) same route in the short time
Enclose the value as N, the such as one week interior difference fastest to family's time with time of getting home the most slowly.
Further, also include the task of completing the heating of sound equipment courage machine according to user setup timing, and start arriving
By communication module, execution instruction is issued to courage machine during the time；
This is simplest start by set date function, the most too much repeats.Preferably, described execution instruction is issued to
Sound equipment courage machine is by realizing data interaction with server wireless network connection, and then by server controls sound equipment courage machine.
Further, vehicle control syetem of the present invention also includes input module and output module.
Its function is, input module sends instructions under being used for carrying out and arranges functional mode.Output module is used for feeding back
The information such as duty.
Further, described input module includes phonetic entry end touch input end, and described touch input end is arranged on
On console and on steering wheel.
The advantage using this scheme is, overcome control button at console, operator need shift sight,
Easily cause the hidden danger that driving is dangerous.Being simultaneously located on steering wheel and console by touch input end, driver exists
Touching the button on steering wheel in traveling and can complete operation, security is greatly improved.Meanwhile, the people in copilot
Member can also assist operator by console.Driver more can directly use phonetic entry to carry out operation control
System, safer reliably.Owing to interior space is little, the installation site of phonetic entry end is not required to be particularly limited to,
As long as the phonetic order of driver can be received.
Further, described output module, including voice output end block and display output, speech output end is used for
The voice messaging of playback process device feedback；Described display output, is used for showing content and providing operation interface, institute
The display output stated is screen；Described screen is arranged on console and steering wheel.
