Description

The network processing controller card that carrier state detects

Technical field

The utility model relates to the network processing controller card that a kind of carrier state detects.

Background technology

Current, single-chip computer control system has been widely used in the every field such as family, industry, but these embedded systems great majority or use separately, with extraneous communication main or by serial ports or other such as 485, the special purpose interface such as CAN realizes.Development along with computer technology and network technology, network communication is increasingly general, the advantage of network communication is to utilize ripe procotol, can realize that teledata is mutual fast, so it is more and more important that equipment and the external world carry out communication by network, general all by control card realization equipment and the connection of being connected, but existing control card only provides single input and list output, the integrated use of inconvenient large number quipments.

The utility model content

The purpose of this utility model is to overcome the shortcoming and defect of above-mentioned prior art, and the network processing controller card that provides a kind of carrier state to detect solves the drawback that prior art inconvenience is used in many equipment connections.

The purpose of this utility model is achieved through the following technical solutions: the network processing controller card that carrier state detects, comprise processor, two PHY modules, the SATA controller, USB controller and PCI bridge, described processor, the SATA controller, the USB controller is connected a pci bus and connects with the PCI bridge, two PHY modules are connected on the gmii interface on the processor, one of them PHY module provides two Ethernet interfaces, another PHY module provides two optical fiber interfaces, described SATA controller provides a CF interface, and the USB controller provides USB interface.

Also be connected with the state-detection display module on the described processor, described state-detection display module is a plurality of LED display lamps, and described LED display lamp is corresponding one by one with each interface.

Also be provided with two RS232 interfaces on the described processor.

Also be connected with the FLASH memory on the described processor.

Described processor is connected with real-time clock (RTC) module and eeprom memory by an iic bus.

The beneficial effects of the utility model are: with two Ethernet interfaces, two optical fiber interfaces, two serial interfaces, can realize that many equipment carry out the data interaction between Ethernet, wide area network, the serial ports, the LED lamp is set in this device the communication conditions of each interface is carried out the outside demonstration, be convenient to the working condition that the staff grasps system.
