Summary of the invention
In order to solve deficiency of the prior art, the utility model provides a kind of and has looked the audio transmission data switching exchane based on coaxial cable, has the port loop inhibit feature, compact conformation, and stability is high.
The purpose of this utility model realizes by the following technical solutions:
Look the audio transmission data switching exchane based on coaxial cable, mainly partly constitute by single-chip microcomputer, exchange chip, network transformer, interface module, power module, network monitoring module, EEPROM, duplexer, low pass filter etc., interface module is connected to exchange chip by network transformer, exchange chip utilizes multichannel composite signal and data wire to be connected with led module, EEPROM and duplexer, EEPROM is connected to single-chip microcomputer, power module is used for power supply, the Detection ﹠ Controling function of port is integrated in forms the network monitoring module on the wiring board.
Described interface module, form by input port and output port, output port mainly is made of RJ45 and F type joint, be integrated with network transformer in the RJ45, has the lightning protection function, there are RJ45 and F type to connect the data upper united mouth of first two form, F type joint upper united mouth can connect mixed signal, RJ45 data upper united mouth is unsettled does not at this moment connect, and can connect vision signal separately yet, and this moment, RJ45 was as the data upper united mouth, there are RJ45 and F type to connect the data second line of a couplet mouth of first two form, RJ45 second line of a couplet mouth is only walked data, and F type joint second line of a couplet mouth is a Hybrid port, can walk vision signal and data simultaneously; Input port is the coaxial cable F type interface and the RJ45 interface DATA input of TV and DATA mixed signal, make input port two-way optional, output port is 5 coaxial cable F type interfaces and two 10M ether data-interfaces, DATA In both can do data input and output interface simultaneously, each port is supported 10Mbps speed, the user can carry out this locality configuration by the CONFIG port, provide isolation between the user based on the VLAN of port, come the communication of Self-cascading or user port to be merely able to be exchanged to trunking port, thereby prevent the reciprocity communication between the user.
Described network monitoring module, integrated design has the embedded monitoring management software in it, can monitor each port and EOC module in real time, when finding that certain port and EOC module have passage obstruction or anomaly, take corresponding measure to remove passage immediately and stop up and lead the reason condition, make system avoid being absorbed in network paralysis, have the port loop inhibit feature.
Described switch adopts the connector mode to be connected with the EOC plate, and compact conformation is convenient to produce debugging.
Owing to adopted above technical scheme, the utlity model has following beneficial effect:
1, a coaxial cable F type TV/DATA mixes input, and a RJ45 interface DATA input has accomplished that input interface is two-way optional;
2,5 F type interface transmission coaxial-cable radio frequency cable TV signals and Ethernet data are set;
3, intelligent port control, the state of detection port and EOC bridge notes abnormalities and recovers automatically;
Radio frequency is straight-through when 4, cutting off the power supply, and does not influence TV and normally watches;
5, all of the port can independently turn-off;
6, automatic MAC address learning and maturation;
7, loop detection and inhibition;
8, external server carries out the automatic and manual configuration based on HTTP/DHCP;
