Description

Wireless communication module comprising MCU

Technical field

This utility model is related to a kind of wireless communication module, more particularly to a kind of to include MCU (Micro Control Unit, micro-control unit) wireless communication module.

Background technology

At present, wireless communication module needs outside addition SIM (Subscriber as a passive communication device Identification Module, client identification module) card circuit, corresponding peripheral circuit could realize corresponding function, Note is such as received and dispatched, called, received and dispatched TCP (Transmission Control Protocol, transmission control protocol)/UDP (Point to Point Protocol, it is right to put for (User Datagram Protocol, UDP) data, PPP Point agreement) or network interface card dial up on the telephone.Also a kind of wireless communication module is to be internally integrated SIM integrated circuits, this wireless Although communication module outside need not add SIM circuit, production cost is also of a relatively high.

Either outside addition SIM circuit, has still been internally integrated SIM integrated circuits, and production cost is higher, and IMSI (International Mobile Subscriber Identification, international mobile subscriber identification) number is solid Fixed, once network signal to be registered is bad, network registry failure may result in and cannot use.

Utility model content

The technical problems to be solved in the utility model is to overcome wireless communication module in prior art to need outside adding Plus SIM circuit or be internally integrated SIM integrated circuits, therefore the defect for causing production cost higher, there is provided a kind of comprising MCU's Wireless communication module.

This utility model is solving above-mentioned technical problem by following technical proposals：

A kind of wireless communication module comprising MCU, its feature are that the wireless communication module includes processing module, penetrates Frequency module, MCU and memory module, the processing module include SIM interface and UART interface, and the MCU is connect with the SIM respectively Mouth and the UART (Universal Asynchronous Receiver/Transmitter, universal asynchronous receiving-transmitting transmitter) Interface is electrically connected, and the processing module is electrically connected with the radio-frequency module and the memory module respectively；

The MCU is used for producing IMSI number information, and the IMSI number information is sent to described by the SIM interface Processing module, the processing module are used for receiving the IMSI number information and producing signal of communication sending to the radio-frequency module, The radio-frequency module is used for receiving the signal of communication and producing radiofrequency signal, and the processing module is additionally operable to the IMSI number Information is sent to the memory module, and the memory module is used for storing the IMSI number information.

In this programme, compared to adding SIM circuit, the low cost of the MCU in addition, therefore reduce described wireless Communication module production cost.

It is preferred that the MCU is used for producing at least 2 IMSI number information, and at least 2 IMSI number information are sent respectively To the processing module.

In this programme, the MCU can be by producing multiple IMSI numbers, and the switching being capable of achieving between operator, so as to keep away Exempt from the network signal registered because of some bad and lead to not situation about using.

It is preferred that the MCU is electrically connected by serial communication with the UART interface.

It is preferred that the wireless communication module is 2G (Generation Mobile Telecommunication System technology) wireless communication module, the 3G (third generations Mobile communication technology) wireless communication module or 4G (forth generation mobile communication technology) wireless communication module.

On the basis of common sense in the field is met, above-mentioned each optimum condition, can combination in any, obtain final product this utility model respectively compared with Good example.

Positive effect of the present utility model is：

The wireless communication module comprising MCU that this utility model is provided is without the need for outside addition SIM circuit or is internally integrated SIM integrated circuits, you can realize corresponding communication function, so as to reduce production cost, and can produce multiple IMSI numbers, can be real Switching between existing operator, leads to not situation about using so as to the network signal for avoiding registering because of some is bad.

Description of the drawings

Structural representations of the Fig. 1 for the wireless communication module comprising MCU of this utility model preferred embodiment.

Specific embodiment

A preferred embodiment is named, and combines accompanying drawing to become apparent from intactly illustrating this utility model.

As shown in figure 1, the wireless communication module comprising MCU that the present embodiment is provided includes MCU1, processing module 3, storage Module 4 and radio-frequency module 5, processing module 3 include SIM interface 21 and UART interface 22, and MCU1 is electrically connected with SIM interface 21, MCU1 is also electrically connected by serial communication with UART interface 22, and memory module 4 and radio-frequency module 5 are electrically connected with processing module 3 respectively Connect, in the present embodiment, the wireless communication module is 2G wireless communication modules, it is not limited to 2G wireless communication modules, 3G wireless communication modules or 4G wireless communication modules can be selected according to practical situation.
