Execution in step S1 after multimedia player is started working starts microprocessing unit and all circuit of microprocessor, and finishes the guiding of required software and the initialization of interior each assembly of elements of microprocessor.
Then, microprocessor execution in step S2 is operated in low frequency mode, and execution in step S3, and the dormancy time of doze output is set, and microprocessing unit enters park mode.Park mode can be the park mode that microprocessing unit carries, and also can realize by coding, and this does not influence realization of the present invention.Simultaneously, multimedia player is in off-mode, not consumed power.
Microprocessing unit wakes back execution in step S4 up, by the voltage condition of power processor detection power unit, and execution in step S5, judge whether power unit is in low-voltage state.If power unit voltage is lower, execution in step S9 then, microprocessing unit enters unlimited park mode, just restarts after power unit is changed battery.If power unit voltage is normal, execution in step S6 then, detect the entry condition of multimedia processor, and execution in step S7, judge whether entry condition is true, if be true, execution in step S8 then, microprocessing unit enters normal mode of operation, otherwise returns execution in step S3, and microprocessing unit enters park mode once more.At this moment, multimedia processor is in off-mode, and microprocessor work is at park mode, and just multimedia player remains on low-power consumption mode.
After microprocessor enters normal mode of operation, will drive multimedia processor and play the multimedia messages that the passenger selects according to passenger's operation, comprise music, film etc., perhaps employing wireless mixed-media network modules mixed-media allows passenger's browsing page, obtains the information such as weather, traffic, hotel of Reiseziel.Certainly, microprocessor also will receive data updated, information such as the music of upgrading as needs, film, and these all can carry out under the microprocessor normal mode of operation.
The flow process of multimedia processor entry condition trace routine is described below in conjunction with Fig. 3.When microprocessor detected the multimedia processor entry condition, at first execution in step S11 according to the detection signal of mobile vibration detection module, judged whether to detect moving or vibration signal more than the frequency threshold value in time span.This time span and frequency threshold value all are written to before microprocessing unit is started working in the storer of microprocessor, and can inquire about these two parameters during microprocessing unit work can acquisition time length and frequency threshold value parameter.
If microprocessor judges detects moving or vibration signal more than the frequency threshold value in time span, execution in step S15 then, otherwise execution in step S12.
Among the step S12, microprocessing unit just judges whether continue to detect the active signal that human body exists in time span by physical activity situation in human detection module length detection time.If continue to detect the human activity signal, execution in step S15 then.If fail to continue to detect the human activity signal in the time span, represent passenger or shopping cart for a long time away from multimedia player, microprocessor execution in step S13.
Among the step S13, microprocessing unit judges whether to receive new ID information of identification code, if the ID identification code that receives changes, execution in step S15 then, otherwise execution in step S14 further judges whether to receive infrared ray or less radio-frequency power-on command, as receives power-on command, execution in step S15 then, otherwise return the execution original program.
Among the step S15, microprocessing unit detects surrounding environment luminance brightness actual value by the environmental light brightness detection module, and contrast_environment luminance brightness actual value and the environmental light brightness upper limit threshold, the lower threshold that are stored in the storer, if the environmental light brightness actual value is between upper limit threshold and lower threshold, execution in step S16, the entry condition of multimedia processor is set to very, continues to carry out original program if surrounding environment luminance brightness actual value not between upper limit threshold and lower threshold, is then returned.
By said method as seen, microprocessor detects when whether starting multimedia processor, need to judge and in time span, detect moving or vibration signal more than the frequency threshold value, perhaps receive power-on command, perhaps receive new ID information of identification code, perhaps continue to detect the human activity signal in time span, and surrounding environment luminance brightness actual value is between environmental light brightness upper limit threshold and lower threshold the time, just the multimedia processor entry condition is set to very.Like this, passenger or shopper are long-time near multimedia player, and the surrounding environment luminance brightness is when being fit to, and multimedia processor just can start, and multimedia player is play the multimedia messages that passenger or shopper need watch.
After multimedia processor starts, microprocessor will detect external condition and whether meet the multimedia processor cut-off condition.The process flow diagram of multimedia processor cut-off condition trace routine as shown in Figure 4.When microprocessor detects the cut-off condition of multimedia processor, execution in step S21 at first, detect surrounding environment luminance brightness actual value by the environmental light brightness detection module, and judge that whether the environmental light brightness actual value is greater than upper limit threshold, execution in step S26 in this way, the entry condition of multimedia processor is set to vacation.If surrounding environment luminance brightness actual value is less than upper limit threshold, execution in step S22 then, judge that whether the environmental light brightness actual value is less than lower threshold, represent then that in this way the surrounding environment luminance brightness is too small, passenger or shopper can't watch multimedia messages, microprocessor is execution in step S26 also, and the entry condition of multimedia processor is set to vacation.If the environmental light brightness actual value is greater than lower threshold, execution in step S23 then.
Among the step S23, microprocessing unit is according to the detection signal of mobile vibration detection module, judges whether not detect in time span moving or vibration signal more than the frequency threshold value, execution in step S24 in this way, otherwise return the execution original program.
Among the step S24, microprocessing unit is by human detection module human body active signal, and judge whether in time span, to fail to continue the human body active signal, if fail to continue to detect the human activity signal, represent passenger or shopper for a long time away from multimedia player, then execution in step S25.If human detection module continues to detect the human activity signal in time span, then return and continue to carry out original program, and the entry condition of multimedia processor is not set to vacation.
Among the step S25, microprocessing unit judges whether do not receive new ID identification code in time span, if do not receive, microprocessor is execution in step S26, and the entry condition of multimedia processor is set to vacation.If microprocessing unit receives new ID identification code in time span, then return the execution original program.
By multimedia processor shutdown testing conditions flow process as seen, when the environmental light brightness actual value is greater than upper limit threshold or less than lower threshold around, the entry condition of multimedia processor is vacation, be that multimedia player does not all start under too bright or too dim environment, to save the electric energy that multimedia player consumes.
Simultaneously, if in time span, microprocessor does not detect above the moving or vibration signal of frequency threshold value, and do not receive new ID information of identification code, and fail to continue to detect the human activity signal, also the entry condition of multimedia processor is set to vacation, and multimedia processor promptly enters shutdown and handles, to save electric energy.
Thus, if passenger or shopping cart are for a long time away from multimedia player, human detection module promptly can't continue to detect physical activity information, mobile vibration detection module also can't detect and move or vibration signal, and multimedia player can not receive new ID identification code yet, multimedia processor is just closed, to save electric energy.
And multimedia player is provided with wireless network module, can get online without being tethered to a cable by wireless network module when the passenger waits, and in time understands the practical information such as weather, traffic, hotel of Reiseziel.In addition, when the passenger waits, also can watch the film that is stored in the storer or listen song etc., multimedia player provides multiple recreation and amusement mode for the passenger, also makes things convenient for the passenger to obtain the information of multiple practicality greatly simultaneously.
Certainly, in the foregoing description, multimedia player is provided with microprocessor and two processors of multimedia processor, and during actual the use, above-mentioned two processors can only realize that by a central processing unit this does not influence enforcement of the present invention.
In addition, because passenger or shopper promote baggage cart or shopping cart when moving ahead, the terrestrial magnetic field detection module will constantly provide detected terrestrial magnetic field signal to microprocessor.Therefore, during practical application, can cancel mobile vibration detection module, microprocessor judges by the variation of the voltage signal magnitude of voltage that detection terrestrial magnetic field detection module provides whether baggage cart or shopping cart are moved.Correspondingly, multimedia processor entry condition trace routine with close in the condition trace routine, microprocessor judges whether to start or cut out multimedia processor by the signal that the signal substituting that detects the terrestrial magnetic field detection module and provide moves the vibration detection module and provides.
Simultaneously, multimedia player is not limited to be applied in that airport lounge, harbour, station waiting room provide the recreation and amusement service for the passenger or play the information of extensive stock in the supermarket, can also be used in tourist district, playing the recommended information at each sight spot, perhaps in places such as exhibition, museum, play the required information of obtaining of various people.
In addition, the time span of human detection module human body active signal and mobile vibration detection module detect the time span of mobile or vibration signal and can be set by the staff, two time spans can be identical, also can be inequality, and this does not influence enforcement of the present invention.
At last, it is emphasized that to the invention is not restricted to above-mentioned embodiment, also should be included in protection scope of the present invention such as the change of time span, the change of environmental light brightness upper limit lower threshold, the subtle change such as change of wireless network module.
