Description of drawings
Fig. 1 is the structured flowchart of the utility model embodiment and intelligent electronic device, external data memory.
Fig. 2 is the workflow diagram of the utility model embodiment.
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
Vehicle-mounted WIFI multimedia electronic equipment of the present utility model is installed on the vehicles such as automobile or train, can with communicate such as intelligent electronic devices such as smart mobile phone, panel computers, and can receive data from external data memory.
Referring to Fig. 1, the vehicle-mounted WIFI electronic multimedia of present embodiment is established 1 and is had controller 10, two WIFI modules 11,12, storer 13, usb 14 and power module, wherein power module is made of transformation module 16 and Voltage stabilizing module 17, transformation module 16 is by accumulator 15 power supply, and power module is to controller 10, two WIFI modules 11, power supplies such as 12.
In the present embodiment, storer 13 can be flash memory (flash) or electrically erasable read-only memory (EEPROM), also can be other nonvolatile memories, store the HTML(Hypertext Markup Language) file in the storer 13, these files can be read, watch by common web browser.The data that storer 13 is stored can be visited by controller 10, and namely controller 10 can read the data that storer 13 is stored, and also can write new data to storer 13.
Two WIFI modules 11 of vehicle-mounted WIFI multimedia electronic equipment 1,12 frequency of operation are inequality, and WIFI module 11 is used for and intelligent electronic device 21, communicate as smart mobile phone etc., and its frequency of operation is lower, is the 2.4G hertz.
WIFI module 12 is used for receiving the data that external data memory 22 sends, and is mainly used in the data that storer 13 is stored are upgraded, and its frequency of operation is higher, is the 5G hertz.Like this, the speed that outside data-carrier store 22 can be higher sends to controller 10 with data, and controller 10 stores the data that receive in the storer 13 into, thereby realizes the Data Update to storer 13 rapidly.For example, automobile can be at short notice by the Data Update of WIFI module 12 realizations to storer 13 when the rest station that rests in midway.
In addition, vehicle-mounted WIFI multimedia electronic equipment 1 also is provided with a usb 14, removable memory 20 can carry out exchanges data by usb 14 and controller 10 as USB flash disk, portable hard drive etc., and controller 10 also just can be by usb 14 visit removable memories 20.Certainly, also store the HTML (Hypertext Markup Language) file in the removable memory 20.
The power module of vehicle-mounted WIFI multimedia electronic equipment 1 comprises transformation module 16 and Voltage stabilizing module 17, transformation module 16 is used for converting the electric energy that accumulator 15 stores to low-voltage DC, and by Voltage stabilizing module 17 low-voltage DC is stabilized in fixing voltage, as 5 volts voltage, and offer controller 10, WIFI module 11,12 and module such as storer 13, usb 14.
The principle of work of vehicle-mounted WIFI multimedia electronic equipment is described below in conjunction with Fig. 2.Vehicle-mounted WIFI multimedia electronic equipment will judge whether to receive request signal after starting, and namely execution in step S1 if receive request signal, judges further whether this request signal is the request signal that issues data, i.e. execution in step S2.The signal that request issues data be by such as intelligent electronic devices such as smart mobile phone, panel computers to the request signal that vehicle-mounted WIFI multimedia electronic equipment sends, ask vehicle-mounted WIFI multimedia electronic equipment to issue the data that are stored in storer or the removable memory to intelligent electronic device.
If vehicle-mounted WIFI multimedia electronic equipment judges that the request signal that receives is the signal that is issued data by the request that intelligent electronic device sends, execution in step S3 then, the WIFI module 11 lower by frequency of operation issues the data that its request issues based on HTTP(Hypertext Transport Protocol) to intelligent electronic device, and execution in step S4, whether judgment data issues finishes, finish as not issuing, then continue to issue data, finish until data distributing.
Because the data that vehicle-mounted WIFI multimedia electronic equipment issues are HTML (Hypertext Markup Language) files, the passenger uses the generic web page browser on the intelligent electronic device namely can read and watch the HTML (Hypertext Markup Language) file.In addition, because intelligent electronic device is visited the data of storing in the vehicle-mounted WIFI multimedia electronic equipment by WIFI, so the speed of data distributing is very fast, even the passenger watches video file, also can watch swimmingly.And the data that intelligent electronic device receives do not use intelligent electronic device by the flow resource of 3G network visit internet all from the local storage of vehicle-mounted WIFI multimedia electronic equipment, save passenger's expense expenditure.
Among the step S2, be not the signal that request issues data if judge request signal, then execution in step S5 judges whether this signal is the signal of Data Update.When vehicle-mounted WIFI multimedia electronic equipment needs data in the updated stored device 13, to receive the data that outside data-carrier store sends by the higher WIFI module 12 of frequency of operation, outside data-carrier store will send the more signal of new data to vehicle-mounted WIFI multimedia electronic equipment this moment.If vehicle-mounted WIFI multimedia electronic equipment judges that what receive is the signal of Data Update, execution in step S6 then, the data that receive from external data memory by WIFI module 12, and the data that receive are stored in the storer 13.
At last, execution in step S7, whether judgment data is upgraded finishes, and finishes as renewal, and then the end data refresh routine does not finish if upgrade, and then continues to receive data, finishes until Data Update.
Certainly, owing to vehicle-mounted WIFI multimedia electronic equipment also is connected with removable memory 20, therefore can be by updating stored in the Data Update that removable memory 20 interior data also can realize vehicle-mounted WIFI multimedia electronic equipment.
The passenger uses intelligent electronic device to be connected with vehicle-mounted WIFI multimedia electronic equipment by WIFI, and receive the data that vehicle-mounted WIFI multimedia electronic equipment issues, the passenger can use the generic web page browser in the intelligent electronic device namely can watch the HTML (Hypertext Markup Language) file like this, need software be installed at intelligent electronic device, and can be at a high speed, receive data at low cost, make things convenient for the passenger in the compartment, to watch data in the storer that is stored in vehicle-mounted WIFI multimedia electronic equipment.
It is emphasized that at last the utility model is not limited to above-mentioned embodiment, also should be included in the protection domain of the utility model claim as the change of the frequency of operation of two WIFI modules, the variations such as change that power module constitutes.
