Abstract
The invention discloses a switching-type Ethernet network bridge with a self error code testing function. The switching-type Ethernet network bridge with the self error code testing function comprises a conversion chip, an Ethernet PHY module, an E1 interface module and a state detection module, wherein the state detection module comprises a processing module, a temperature detection module and a communication detection module. The processing module is connected to the conversion chip, and the temperature detection module and the communication detection module are connected to the processing module. The switching type Ethernet network bridge with the self error code testing function has an advantage that the state detection module is arranged to monitor operation of the bridge, and accordingly when states including error codes or abnormal temperature occur, alarming is carried out, and maintenance staff can rapidly carry out repairs according to displayed faults.
Description
Technical field
The present invention relates to a kind of bridge, particularly relate to a kind of switching Ethernet bridge that carries error code testing function.
Background technology
Bridge (Bridge) is as a clever repeater.Repeater receives signal from a network cable, amplifies them, is sent into next cable.Comparatively speaking, bridge is sharper to the information handing down from the outpost of the tax office.Bridge is a kind of technology that frame is forwarded, and according to MAC blockette, can isolate collision.Bridge couples together a plurality of network segments of network in data link layer.
Bridge couples together two similar networks, and the circulation of network data is managed.It works in data link layer, distance or scope that not only can extended network, and performance, reliability and the fail safe that can improve network.After network 1 is connected by bridge with network 2, bridge receives the packet that network 1 sends, check the address in packet, if address belongs to network 1, it is just abandoned, on the contrary, if the address of network 2, it just continues to send to network 2. can utilize bridge isolation information like this, and same network number is divided into a plurality of network segments (belonging to same network number), isolate the safe network segment, prevent the user's unauthorized access in other network segments.Due to the segmentation of network, each network segment relatively independent (belonging to same network number), the fault of a network segment can not have influence on the operation of another network segment.
Existing bridge, when breaking down, needs maintenance person to go to check that fault makes mistakes a little, expends a large amount of time, and there is no warning function, only quits work and could be perceiveed having damaged, and has stopped the possibility of repairing.
Summary of the invention
Object of the present invention is to overcome the deficiency of present technology, and a kind of switching Ethernet bridge that carries error code testing function is provided, and solves existing bridge and need to expend the shortcoming of plenty of time when repairing.
The present invention is achieved through the following technical solutions: the switching Ethernet bridge that carries error code testing function, comprise conversion chip, ethernet PHY module, E1 interface module and state detection module, on described conversion chip, be provided with HDLC interface and MII interface, described E1 interface module is connected on the HDLC interface of conversion chip, ethernet PHY module is all connected on the MII interface of conversion chip, described state detection module comprises processing module, temperature detecting module and communication check module, described processing module is connected to conversion chip, temperature detecting module and communication check module are connected in processing module, on conversion chip, be also connected with a synchronous DRAM and clock module.
Described conversion chip adopts xBridge2.0 chip.
On described state detection module, be connected with display module and alarm.
Described display module is display or indicator light.
The invention has the beneficial effects as follows: this device arranges state detection module, the operation of device is monitored, when there is the states such as error code, temperature anomaly, report to the police, maintenance personal can place under repair fast according to the fault showing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but structure of the present invention is not limited only to following examples:

Conversion chip of the present invention adopts xBridge2.0 chip, and this chip can be realized the connection between local area network (LAN) and wide area network; Ethernet PHY module adopts AC101-TF chip, connects outside Ethernet, completes transmission and the data processing of Ethernet data bag; E1 interface module adopts XRT82D20 chip, connects outside wide area network, and the signal of wide area network is carried out to line coding, decoding, and the function that completes jitter suppression.
On described state detection module, be connected with display module and alarm, display module is display or indicator light, processing module in state detection module adopts LPC2210 flush bonding processor, communication check module is mainly monitored the communication conditions between conversion chip, ethernet PHY module, E1 interface module three, the working temperature of temperature detecting module supervising device; While there is the situations such as error code, temperature anomaly at device, communication check module and temperature detecting module transmit a signal to processing module, and processing module is controlled alarm equipment alarm and is shown to staff by display module, and display indicates or indicator light indication.
When the present invention uses, need pairing to use, between two wide apart local area network (LAN)s and wide area network, this device is all set, can realize easily the transparent interaction of data between two wide apart local area network (LAN)s.
