Description

Network communication controller with multiple up going port communication modes

Technical field

The utility model relates to a kind of network communication controller, particularly a kind of network communication controller with multiple up going port communication modes.

Background technology

Serial server or network communication controller are host computer is passed in a kind of data acquisition induction-arrangement protocol conversion of the equipment with down going port by up going port networked devices, traditional network communication controller all is based on single-chip microcomputer, resource and speed are limited, be difficult to the Coordination Treatment of a plurality of interfaces of expansion and a plurality of tasks, can't accomplish multiple interfaces and high speed communication.Therefore has only simple and single up going port communication modes, can not satisfy the demand of the different up going port connected mode of different users, bring the user many inconvenience is arranged, particularly can't realize the requirement of the required multiple interfaces compatibility mode of user, increase the use cost of the many Application of Interface of user.

Summary of the invention

Goal of the invention: the utility model provides a kind of network communication controller with multiple up going port communication modes at the deficiencies in the prior art.

Technical scheme: a kind of network communication controller described in the utility model with multiple up going port communication modes, it comprises the down going port that contains the RS485 interface, it is characterized in that, it also comprises the ARM9 processor that links to each other with down going port, and the up going port that links to each other with the ARM9 processor is provided with ethernet controller interface module, RS232 interface module and RS485 interface module; The networked devices of up going port can read the data of the networked devices of down going port from the arbitrary interface module ethernet controller, RS232 or the RS485 of the up going port of network communication controller.

Beneficial effect: the utility model can possess the network communication controller of multiple communication modes simultaneously, made things convenient for user's host computer configuration networking, can greatly facilitate the demand of different users's networking monitoring, help the compatibility between difference and the interface equipment, save cost.

Description of drawings

Fig. 1 is the module map with network communication controller of multiple up going port communication modes.

Embodiment

As shown in the figure, the resourceful ARM9 processor of processor adopting of network communication controller with multiple up going port communication modes is as kernel, selected processor self has three serial ports, with a SPI interface, expand two serial ports very easily again by the SPI interface, and processor has also been expanded ethernet controller very easily.The down going port that is connected with the ARM9 processor is provided with 4 RS485 interfaces and is used for being connected with downstream plant.Connected up going port comprises ethernet controller interface module, RS232 interface module and RS485 interface module.During use, the user can be as required, can switch the RS485 of up going port and the selection of RS232 by inner short circuit cover, and the data acquisition induction-arrangement protocol conversion of the equipment of down going port by the arbitrary interface in the up going port, is uploaded to the networked devices of host computer,

The processor embedded OS of can packing into, can realize the management and dispatching coordination parallel processing of a plurality of tasks, thus realize the real-time communication of up going port Ethernet and serial port very easily, and the real-time communication of four serial ports of down going port, improve communication speed, also made things convenient for user's interface.

Claims (1)

1, a kind of network communication controller with multiple up going port communication modes, it comprises the down going port that contains the RS485 interface, it is characterized in that, it also comprises the ARM9 processor that links to each other with down going port, and the up going port that links to each other with the ARM9 processor is provided with ethernet controller interface module, RS232 interface module and RS485 interface module; The networked devices of up going port can read the data of the networked devices of down going port from the arbitrary interface module ethernet controller, RS232 or the RS485 of the up going port of network communication controller.
