The EOC host machine comprises an EOC module, an Ethernet access management exchange chip, and an Ethernet interface. The EOC module comprises an EOC control module and a filter, an Ethernet access chip, a Flash, and a RAM. The Ethernet access chip is connected with the Ethernet access management chip. The filter is connected with a coaxial cable. A signal detection circuit is disposed between the EOC control module and the Ethernet access management exchange chip. The host machine is used as the EOC host machine.
Description
Technical field
The utility model relates to the EOC technical field, and a kind of EOC main frame with the autoboot function is provided.
Background technology
EOC (Ethernet Over Coax) technology is exactly that the IP data are mixed with cable TV signal after treatment, and by same coaxial cable access user, thereby has good adaptability, and neatly networking, its overcome former multiple network bidirectional rebuilding scheme register one's residence constructional difficulties, cover the problems such as cost height and transformation cycle be long, and its access bandwidth can satisfy at present and the demand of significant period of time in future, the present requirement of a kind of adaptation, and high performance-price ratio data access scheme easy to implement.In recent years, the EOC technology based on the cable tv coax data signal obtains develop rapidly.Although present multiple EOC technology technical system is different, all can be applicable to cable TV network, by the coaxial cable transmission of data signals, to finish the co-cable transmission that realizes voice, data, video, realize the integration of three networks of television network broadcast.
Active EOC technology is that data-signal is modulated on the radio-frequency carrier by the technical system of determining, is beneficial to transmit at Cable, passes through constructed restoring data signal at user side again.
At present, the EOC main frame has restarts the also many of function, but the equipment that also do not have that has is restarted function, need to restart all and must realize restarting function by artificial outage.The concrete method for restarting of present stage is as follows:
1, manual power-off restarting EOC main frame
When can only then again switching on by manually outage that equipment reconfigures or crashes, restart the EOC main frame.
2, restart the EOC main frame by order
Restart the EOC main frame by order, this mode shows slightly advantage than front a kind of mode, can Remote configuration equipment, and utility command realizes restarting function.Main frame does not crash but prerequisite needs EOC, if crash, needs artificial power-off restarting.
3, restart the EOC main frame by WEB or webmastering software
Carry out configuration and the management of EOC main frame by WEB or webmastering software, compare this method and be better than front two kinds of methods, many functions of network management also can remote reboot.But the deadlock situation appears in equipment, and that also needs manually to arrive the device context power-off restarting.
Summary of the invention
The utility model provides a kind of stability that can improve the EOC local side for the deficiencies in the prior art, improves the stability of network, reduces a kind of EOC main frame with the autoboot function of attendant's workload.
The utility model is by the following technical solutions to achieve these goals:
A kind of EOC main frame with the autoboot function, comprise the EOC module, network interface management exchange chip, Ethernet interface, the EOC module comprises EOC control module and the filter that is connected with the EOC control module, the network interface chip, Flash, RAM, described network interface chip is connected with the network interface managing chip, described Ethernet interface is connected with network interface management exchange chip, described filter connects coaxial cable, it is characterized in that: be provided with signal deteching circuit between described EOC control module and network interface management exchange chip, between network interface management exchange chip and the EOC control module, mutually transmit to the other side, when signal that the inspection of network interface management exchange chip is returned less than the EOC control module, network interface management exchange chip managing chip is with regard to the whole device of autoboot.
In the such scheme, described EOC control module comprises chip AR7410 and chip AR1500, and described AR7410 is connected with AR1500, and described AR1500 connects filter, and described AR7410 connects the network interface chip.
In the such scheme, described network interface management exchange chip also is connected with the JTAG/ICE interface, URAT interface, 2 RAM and Flash.
In the such scheme, described network interface management exchange chip adopts multiport exchange chip KSZ8695.
The utlity model has following beneficial effect:
The utility model crashes such as burst, and the hardware automatic detection function is as short as several seconds as many as and can finishes the connection registration by autoboot in one minute, reduces maintenance, farthest improves internet security and network stabilization.
Description of drawings
Fig. 1 is the utility model system block diagram.
