Description

The 3G wireless communication module

Technical field

The utility model relates to wireless communication technology, is specifically related to a kind of 3G wireless communication module for realizing radio communication.

Background technology

3G(3rd-generation, 3G) be the 3G (Third Generation) Moblie technology, refer to support the honeycomb mobile communication technology of high speed data transfer.The 3G service can transmit sound and data message simultaneously, and speed is generally more than hundreds of kbps.In the prior art, the 3G wireless communication module generally is built in the main equipment, for example set up this module at panel computer or tax control machine, can realize that main equipment carries out information interaction by the 3G wireless network, but this be built in 3G wireless communication module in the main equipment general with the shared processor of main equipment, increased the utilance of processor, reduced the speed of service of main equipment, simultaneously, the 3G wireless communication module of this structure does not have versatility, namely cannot move to other main equipment from a main equipment and use.Relative with built-in 3G wireless communication module, external 3G wireless communication module has stronger versatility, usually, external 3G wireless communication module is that the 3G card of surfing Internet directly is plugged on port corresponding to main equipment, it also is to need to adopt the processor of main equipment to carry out information processing, and self does not have disposal ability and storage capacity.

The utility model content

For the deficiencies in the prior art, it is a kind of from provided with processor and the very strong 3G wireless communication module of versatility that the utility model provides, and it can use quickly and easily and carry out the 3G radio communication in multiple main equipment.

For achieving the above object, the utility model adopts following technical scheme:

The 3G wireless communication module, it comprises processor, internal memory, flash memory, power supply, and described internal memory, flash memory and power supply all link to each other with processor, and described processor is provided with a USB HOST interface, and described USB HOST interface is connected to a 3G card of surfing Internet.

Preferably, described 3G wireless communication module comprises that further one is used for the USB device of storage, and described USB device links to each other with processor, and USB device is stored the information that this 3G wireless communication module receives, and has avoided information loss.

Preferably, described processor also is provided with a UART interface, the external main equipment of described UART interface, realize the information interaction of 3G wireless communication module and main equipment, this main equipment can be panel computer or tax control machine or other can external 3G wireless communication module equipment.

Preferably, described processor is TCC8902, and TCC8902 is the microprocessor that Telechips company adopts ARM11, and it is based on the 65nm manufacture craft, and frequency reaches 650MHz – 800MHz.

The 3G wireless communication module that the utility model is set forth, compared with prior art, its beneficial effect is: the utility model 3G wireless communication module is from provided with processor, self have operation and disposal ability, can be placed on the multiple main equipment, highly versatile, and simplified the input and output work of host device processor, do not affect the speed of service of main equipment, and it uses simple, convenient, only need be connected with main equipment by corresponding interface and get final product, himself also have simultaneously and stores and other wireless communication abilities, for main equipment realization radio communication provides multiple channel.

Description of drawings

Accompanying drawing 1 is the structured flowchart of the utility model 3G wireless communication module;

Accompanying drawing 2 is the application schematic diagram of 3G wireless communication module.

Embodiment

Below, by reference to the accompanying drawings and embodiment, 3G wireless communication module of the present utility model is described further, so that clearerly understand the utility model technological thought required for protection.

As shown in Figure 1,3G wireless communication module 100, it comprises the 3G wireless communication module, it comprises processor 1, internal memory 2, flash memory 3, power supply 4, described internal memory 2, flash memory 3 all links to each other with processor with power supply 4, wherein, internal memory 2 adopts DDR2 internal memory (adopting the FBGA packing forms), flash memory 3 adopts NAND FLASH flash memory (the non-linear macrocell pattern of its inner employing, for the realization of solid-state large-capacity internal memory provides cheap effective solution), power supply 4 is Switching Power Supply, and its output voltage has 3.3V, 1.8V, 1.4V, 1.2V, can satisfy the voltage requirements of processor and other structures.Processor 1 is provided with a USB HOST(USB holotype) interface 12, this USB HOST interface is connected to a 3G card of surfing Internet 6, realizes the 3G radio communication.

For the information that this 3G wireless communication module 100 is received is stored, avoided information loss, comprising also in the 3G wireless communication module that one is used for the USB device 5 of storage, the OTG(On-The-Go that this USB device 5 is provided with by processor) interface links to each other with processor 1.

Thereby 3G wireless communication module 100 and main equipment 7 be by processor 1 be provided with a UART Interface realization the two be connected realize information interaction, this main equipment 7 can be panel computer or tax control machine or other can external 3G wireless communication module equipment.

As preferred version, processor 1 adopts the TCC8902 processor, and TCC8902 is the microprocessor that Telechips company adopts ARM11, and it is based on the 65nm manufacture craft, and frequency reaches 650MHz – 800MHz.
