Yet,, find to exist inconvenient to the power supply that inserts floor road Ethernet switch and optical network unit at user side along with large-scale networking and operation; Difficulty of construction is big; Operation and maintenance expenses are with high, and many shortcomings such as management inconvenience have been brought very big inconvenience to broadband operation.Mainly adopt upper end remote power feeding mode to inserting floor road Ethernet switch and optical network unit at present; This mode is to merge to a network port to the signal of remote exchange and power supply; Be transferred to the corridor switch to data and power supply simultaneously through transmission medium; But the upper end remote power feeding is owing to receive the restriction of ethernet twisted pair transmission range to estimate the influence of thunder and lightning, and used practicality receives great limitation, simultaneously; No matter the no user online is arranged; Remote power feeding equipment all always to this city corridor Ethernet switch and optical network unit power supply, has increased the useful life that O&M cost has also reduced Ethernet switch and optical network unit simultaneously, and therefore solution is very urgent to the problem of the power supply of equipment such as corridor switch and optical network unit.
Summary of the invention
The purpose of the utility model is to provide network signal monitor-type wideband data adapter, and it is low to overcome in the prior art the effective power resource utilization rate of wideband data adapter, has the defective of potential safety hazard in short, the feeding circuit in wideband data adapter useful life.
To achieve these goals, the technical scheme of the utility model employing is following:
Network signal detects the molded breadth tape adapter unit, comprises the computer network interface card interface, detection module, control module, AC-DC module and the Ethernet access device interface that connect in order, and the mains supply interface that is connected with the AC-DC module.
Further, said detection module comprises the integrated operational amplifier that is connected with computer network interface card interface, with signal input part and the signal output part of this integrated operational amplifier is connected, signal output part is connected with control module signal generator.
Further, said control module comprises the trigger that is connected with the signal output part of signal generator, with the switching circuit that signal discrepancy end is connected with the output of this trigger, signal output part is connected with the AC-DC module.
Again further, said mains supply interface is connected with the 220V AC network.
Compared with prior art, the beneficial effect of the utility model is:
1. the utility model can detect the signal of user computer network interface card automatically, and starts voluntarily to the ethernet end device power supply, thereby obtains network signal.
2. when the utility model detects the user and breaks off network, can turn-off voluntarily, accomplish unloaded zero output, save the energy.
3. when current supply circuit and terminal equipment short circuit, can close automatically, thereby reach the protection self and the purpose of terminal equipment.
4. the utility model has been eliminated the potential safety hazard in the feeding circuit, and it is low to have overcome feeding circuit electric energy availability, has prolonged the useful life of equipment greatly, has improved the practical value of adapter.
