The utility model relates to a serial port wireless network card with a mobile storage function, which is composed of a serial port interface, a WLAN baseband chip, a radio frequency module, a NAND Flash storage device, an EEPROM (electrically erasable programmable read-only memory), an antenna and a power chip set. The serial port wireless network card provided by the utility model has the mobile storage function, and has a WLAN wireless network card function.
Description
Technical field
The utility model relates to a kind of serial ports wireless interface module with Mobile Storage Function MSF, it can be used as mobile storage and uses, for the low side devices of only having serial ports provides mobile storage and wireless network card dual-use function, for the low side devices user provides mobile storage and wireless transmission flexibly.
Background technology
At present, the USB interface mobile storage is a kind of very popular mobile memory medium, and it provides easily has the storage of data mobile on the equipment of hi-speed USB interface, mutual function, and the WLAN wireless technology also becomes the standard technique of numerous network applications day by day.But also exist a large amount of equipment at industrial circle at present and adopt the low side processor, it does not have hi-speed USB interface, a lot of equipment needs again a large amount of data storage and transmission.How serial ports Mobile Storage Function MSF and serial ports wireless network card are combined, the equipment for the low side devices user provides mobile storage and wireless transmission, do not have ripe solution at present.
The utility model content
The utility model has well been realized the combination of serial ports mobile storage and serial ports wireless network card, for the low side devices user provides mobile storage and wireless transmission flexibly.
A kind of serial ports wireless network card with Mobile Storage Function MSF, by serial interface, WLAN baseband chip, radio-frequency module, NAND Flash memory, EEPROM, antenna and power supply chip, formed, the WLAN baseband chip is comprised of serial ports, CPU core, parallel data grabbing card, coordinate radio-frequency module and antenna to realize wireless network card function, the data of user's storage can be stored in to the function that NAND Flash storage medium is realized mobile storage by parallel data grabbing card; Signal is converted to the signal of 802.11 serial protocols through the WLAN baseband chip, radio-frequency module is modulated into the baseband signal of 802.11 serial protocols the radiofrequency signal of 2.4GHz or 5GHz, through antenna and other WLAN wireless device communications.The data of user's storage store NAND Flash into by the parallel data mouth or read from NAND Flash, have realized the function of mobile storage.
Process wireless network data and mobile storage data by the WLAN baseband chip shunting with CPU core.Its concrete technical scheme is as follows:
The WLAN baseband chip data type good according to predefined with CPU core, can accurately judge the data type that host computer sends, and store in NAND Flash as network data processing or as the mobile storage data respectively according to different data types.The realization that WLAN baseband chip and radio-frequency module and antenna are complete the function of wireless network, network data has realized the wireless network data interactive function by this link processing; The mobile storage data processor stores NAND Flash into by the parallel data mouth or reads from NAND Flash, has realized the function of mobile storage.
In the utility model, the WLAN baseband chip has serial ports, CPU core and parallel data grabbing card.
In the utility model, NAND Flash memory is directly connected on the WLAN baseband chip by parallel data grabbing card, and NAND Falsh is as mobile memory medium, and the WLAN baseband chip directly is stored in user's data in NANDFlash.
The beneficial effects of the utility model are, wireless and Mobile Storage Function MSF have been integrated on the equipment with serial ports, and the user can realize wireless network and Mobile Storage Function MSF flexibly by the AT+ instruction.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Concrete connected mode of the present utility model as shown in Figure 1, wherein:
The 1st, serial interface, the 2nd, power supply, the 3rd, there is the WLAN baseband chip of CPU core, the 4th, EEPROM, the 5th, radio-frequency module, the 6th, antenna, the 7th, NAND Flash.
Wherein the serial interface part is mainly network interface card and other equipment for connecting Mobile Storage Function MSF; The power unit Main Function is that the power supply of introducing by interface is converted into to different voltage sources according to the needs of each device of network interface card of Mobile Storage Function MSF.
Main Function with WLAN baseband chip part of CPU core is that wireless network data and mobile storage data are processed in shunting.
Wireless network card function of the present utility model partly comprises that WLAN baseband chip with CPU core and assembly thereof, radio-frequency module, antenna form.802.3 network signal be converted to the signal of 802.11 serial protocols through the WLAN baseband chip, radio-frequency module is modulated into the baseband signal of 802.11 serial protocols the radiofrequency signal of 2.4GHz or 5GHz, passes through antenna and other WLAN wireless device communications.
Mobile storage of the present utility model partly comprises that WLAN baseband chip and NAND Flash with CPU core form.The user passes to the mobile storage data by the AT+ instruction WLAN baseband chip with CPU core, and baseband chip stores the mobile storage data into NAND Flash again.
Industrial circle low side processor device use the utility model can be by realizing wireless network and Mobile Storage Function MSF by the AT+ instruction flexibly.
