Description
Technical field
This utility model relates to M2M moving communicating field, particularly relates to the M2M module of a kind of built-in SIM.
Background technology
Along with popularizing of mobile communication technology application, mobile communication technology is applied to Internet of Things, industrial automation
Demand get more and more.At present, SIM will not be built in inside modules by each M2M Module manufacturers, needs module user at oneself
Circuit on increase SIM interlock circuit, use external SIM, but this method all have an obvious shortcoming:
1. need user to increase extra SIM circuit, add hardware cost.
The most external SIM easily occurs that the situation of loose contact, impact use.
The most external SIM circuit adds the design difficulty of Electro Magnetic Compatibility.
These three shortcoming can bring various problem during design and use, makes troubles to the application of M2M module.
Summary of the invention
For the problems referred to above, this utility model provides the M2M module of a kind of built-in SIM, makes the fastness of SIM more
Height, the application circuit of M2M module more simplifies, and uses more convenient.
The technical solution adopted in the utility model is:
A kind of M2M module of built-in SIM, including radio frequency unit, network communication unit, data and control processing unit and
UART/SPI interface, radio frequency unit, network communication unit, data and control processing unit be embedded in M2M module, UART/SPI connects
Mouth is located at M2M module-external, and radio frequency unit is connected with network communication unit both-way communication, network communication unit and data and control
Processing unit two-way communication connects, and data and control processing unit are connected with UART/SPI interface both-way communication, in M2M module also
Being built-in with SIM unit, it is embedded with SIM, and SIM unit is connected with network communication unit both-way communication.This utility model
SIM is directly integrated in M2M inside modules, and built-in SIM is initialized by module when initializing, and reads relevant
Authentication information, after being connected to network, starts network transmission function.
Further, described network communication unit is GPRS communication unit, gsm communication unit, 2G communication unit, 3G communication
One in unit, 4G communication unit.
Further, described radio frequency unit includes antenna, wave filter, amplifier and the wireless transceiver being sequentially connected with, real
Existing conversion between air analog signal and digital signal.
SIM is built in M2M inside modules by this utility model, and the hardware cost and the hardware designs that reduce client are complicated
Degree, adds the reliability of equipment.

Detailed description of the invention
The M2M module of a kind of built-in SIM, as it is shown in figure 1, be provided with radio frequency unit 1, GPRS communication unit in M2M module
Unit 2, data and control processing unit 3 and SIM unit 5.Radio frequency unit 1 includes the antenna 11 being sequentially connected with, wave filter 12, puts
Big device 13 and wireless transceiver 14, radio frequency unit 1 is connected with GPRS communication unit 2 both-way communication, for realizing wireless signal
Conversion between transmitting-receiving and GPRS analogue signal and digital signal.GPRS communication unit is two-way with data and control processing unit
Communication connects, for encoding data according to procotol and decoding.Data and control processing unit 3 and be located at M2M mould
UART/SPI interface 4 both-way communication outside block connects, and this unit, as the control core of M2M module, is built-in with GPRS network
Driver, UART/SPI driver and Network ← → UART/SPI data penetration transmission control program, it is achieved that to number of modules
Control according to transparent transmission process.SIM unit 5 is connected with GPRS communication unit 2 communication, equipped with SIM in SIM unit 5.
Workflow of the present utility model is as in figure 2 it is shown, M2M inside modules is integrated with SIM chip, and module is initializing
Time, built-in SIM is initialized, and reads relevant authentication information, after being connected to GPRS network, start network transmission merit
Energy.
