Description

A kind of serial port networked module

Technical field

The utility model relates to a kind of electronic module, particularly a kind of serial port networked module.

Background technology

So-called serial port networked module is exactly the electrical unit module serial communication of MCU being converted into ethernet communication, and serial ports is but familiar with for Electronics Engineer again, Serial, UART, RS232, EIA-RS-232C, COM these be all the name of serial ports.Serial ports uses pin few (only having RXD, TXD two lines) due to it, and agreement is simple, and be widely used in the data transmission of electronic equipment, electronic equipment communicate with PC by serial ports, or to be undertaken that external data expands by serial ports be all very general phenomenon.The arrival of cybertimes, also networks in the urgent need to electronic equipment, so when an equipment needs access network based on ethernet time, adopts serial ports to turn the mode of Ethernet the most suitable.And similar products ubiquity in the market poor compatibility, compatibility interface is few, is difficult to Secondary Design, does not support the shortcoming that complicated user application is developed.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of compatible good, and compatibility interface is enriched, and facilitates the serial port networked module of one of user's Secondary Design and the exploitation of complicated user application.

For solving the problems of the technologies described above, the utility model realizes as follows: design a kind of serial port networked module, and it is made up of CPU module, memory module, power module, double contact pin interface, GPLO interface module, UART interface module, SPI interface, IIC interface, network interface and USB interface; CPU module is electrically connected with memory module composition data; CPU module and memory module are electrically connected with double contact pin interface, GPLO interface module, UART interface module, SPI interface, IIC interface, network interface and USB interface composition data respectively; Power module is that above-mentioned each module and interface are powered by circuit.

Further, carry out the speed of data processing in order to accelerate computing machine, described CPU module adopts technical grade ARM9 embedded microprocessor, and dominant frequency is 200MHz.

Further, the conveniently exploitation of user's Secondary Design and complicated user application and hardware circuit design, described double contact pin interface is the double contact pin interface of two group of 40 pin 2.54mm.

Further, in order to high-peed connection Ethernet, described network interface is 10/100Mbps adaptive industrial Ethernet card.

Further, in order to better other interface compatible, as be converted to the interfaces such as RS232/RS422/R485 by outer shifting circuit, described UART interface module is made up of 12 3.3VTTL level UART interface.

Further, in order to design the serial equipment networking being suitable for certain applications, described GPLO interface module is made up of 16 GPIO interfaces able to programme.

Further, in order to compact and be convenient to user's Secondary Design, described serial port networked module size is 120mm × 90mm × 12mm.

Good effect of the present utility model: maximum 12 serial equipments can be connected to Ethernet by the utility model, and support SPI, IIC, USB and multichannel GPIO interface, by using this networking module, user has only needed simple periphery circuit design, the serial port device network server being suitable for certain applications can be designed, realize serial ports I/O equipment to the seamless link of Industrial Ethernet and bidirectional data transfers, various custom feature can be realized simultaneously; Technical grade ARM9 embedded microprocessor is adopted to build, configuration mass storage, run built-in Linux operating system, support multiple file system and complete ICP/IP protocol stack, built-in WebServer is used for optimum configurations and equipment control, support SNMPMIB-II Network Management Protocol, powerful function is that user provides the solution of competitive embedded serial ports to Industrial Ethernet, and power consumption is less than 2W.
