Description

A kind of low-power consumption WIFI module

Technical field

The utility model relates to a kind of WIFI module, relates in particular to a kind of WIFI module of super low-power consumption.

Background technology

Internet of Things is a present popular research direction both domestic and external, the what is called Internet of Things is exactly the information exchange that various transducers in company's life collect to be crossed wireless sensor network be connected with the Internet, to realize a kind of network to intellectuality identification, location, tracking, monitoring and the management of object.

In Internet of Things is built, be the core component of Internet of Things as wireless transmission function, yet present wireless transport module ubiquity power consumption is high, bulky shortcoming.

Summary of the invention

For addressing the above problem, the utility model provides a kind of low-power consumption WIFI module.

The WIFI module that the utility model provides comprises 32 single-chip microcomputers, the WIFI chip, and antenna, the Flash memory, switch, wherein WIFI chip, Flash memory, switch, antenna all are connected with single-chip microcomputer.

The WIFI chip comprises a mac processor, RF transceiver, RF front end and application processor.

Wherein said WIFI chip adopts high pass WIFI chip AR4100.

This utility model patent possesses stand-by power consumption less than 4 micromicroamperes, simultaneously do not need operating system and driver to get final product work, can be widely used in medical treatment, transducer and Internet of Things, RFID field, mainly solved high bandwidth (150Mbps), free drive is moving, low-power consumption, the technical problems such as small size, simple to operate and support complete software secondary development, be suitable for very much all kinds of embedded systems, Internet of Things, intelligence sensor field.Company's product is widely used in wireless senser, medical treatment, the fields such as data acquisition at present.

Description of drawings

Fig. 1 is the schematic diagram of implementation method of the present utility model;

Fig. 2 is that the WIFI module synthesis that the utility model provides is used schematic diagram.

Embodiment

As shown in Figure 1, hardware components of the present utility model mainly comprises 32 single-chip microcomputers 1, WIFI chip 2, Flash memory 3, antenna 4 and switch 5.Wherein WIFI chip, Flash memory, switch, antenna all are connected with single-chip microcomputer.

The utility model uses high pass WIFI chip AR4100 and EFM single-chip microcomputer to form super low-power consumption WIFI module.

Single-chip microcomputer 1 adopts 32 Cortex-M3, in traditional single-chip microcomputer field, has some to be different from the requirement that general 32 bit CPUs are used.At industrial control field, customer requirements has the speed of interrupting faster, and Cortex-M3 has adopted the Tail-Chaining interrupt techniques, fully interrupts processing based on hardware, can reduce at most by 12 clock periodicities, can reduce in actual applications 70% and interrupt.

WIFI chip 2 is integrated tcp protocol stack comprises a mac processor, RF transceiver, RF front end and application processor.

Flash memory 3 is used for depositing WIFI driver and user data.

2.4G paster antenna 4 is used for wireless signal transmission and reception.

MOS switch 5 can be turned off wireless portion when module is not worked.

Fig. 2 uses schematic diagram for the WIFI module synthesis that utility model provides.

The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of the utility model protection.
