Problems solved by technology

The disadvantages of this kind of network mainly include: because CMTS is relatively expensive, many users usually share one CMTS, so the bandwidth that each user can enjoy is quite small; CMTS and CM (each user needs a CM) are relatively expensive , so the investment cost of network construction is high; when users upload data, the noise from each user will generate a huge noise at the signal convergence point (that is, "funnel effect"); since many users share one CMTS, when a certain user equipment appears When a fault occurs, it must be checked one by one, making maintenance difficult

Embodiment 1

[0035] As shown in Figure 1 and Figure 2, this regional integrated information access system includes an integrated information access device and a user terminal information device;

[0036] The integrated information access device includes:

[0037] The passive optical network unit data module 1 converts the downlink data optical signal into a data Ethernet signal and transmits it to the switch module 2, converts the uplink data Ethernet signal from the switch module 2 into a data optical signal and uploads it;

[0038] The switch module 2, after distributing and exchanging the data Ethernet signal from the passive optical network unit data module 1, transmits it to the corresponding Ethernet multiplexer 50 in the Ethernet multiplexer module 5; After the uplink data Ethernet signal of module 5 is processed, it is transmitted to passive optical network unit data module 1;

[0039] The cable TV optical receiving module 3, after processing the received TV optical signal, output...

Embodiment 2

[0054] As shown in FIG. 5 , the TV signal receiving and processing module in this embodiment is a radio frequency signal amplifier module 13 , that is, the radio frequency signal amplifier module 13 replaces the cable TV light receiving module 3 in the first embodiment. Radio frequency signal amplifier module 13 is provided with radio frequency signal amplifier, the radio frequency signal input interface of radio frequency signal amplifier connects TV signal input cable 14, the radio frequency signal output interface of radio frequency signal amplifier (this radio frequency signal output interface is the radio frequency signal output of radio frequency signal amplifier module Interface) is connected to the corresponding radio frequency interface in the Ethernet multiplexer module 5 through the distributor 4, after the radio frequency signal amplifier in the radio frequency signal amplifier module 13 amplifies the TV radio frequency signal from the TV signal input cable 14, after...

Abstract

The present invention provides a regional comprehensive information access system, which comprises a comprehensive information access device and a user terminal information device; an Ethernet wave coupling device module and a network management module are arranged in the comprehensive information access device, one or more Ethernet wave coupling device(s) are contained in the Ethernet wave coupling device, and an Ethernet wave coupling device is contained in the user terminal information device; the mixed signal interface of the Ethernet wave coupling device in the user terminal information device are connected with the mixed signal interface of the corresponding Ethernet wave coupling device in the comprehensive information access device through a coaxial cable. The present invention can process the data signal and the television signal to form a data / television mixed signal, the signal is transmitted to the user through a coaxial cable, the television signal and the data signal are separated at the user terminal, and the data signal and the television signal are not affected during the transmission; the funnel effect can be effectively eliminated; the maintenance is easy, and convenient; and the present invention has a perfect network management function.

Description

technical field [0001] The present invention relates to a cable signal transmission system, in particular to a regional integrated information interface capable of mixing cable television signals and data signals and transmitting them to users through the same coaxial cable, and separating cable television signals and data signals at user terminals. This regional integrated information access system is suitable for integrated information access in areas such as residential quarters and buildings. Background technique [0002] At present, the cable TV network used by radio and television stations to transmit TV signals (one-way transmission) is the HFC network. The HFC network is a hybrid network composed of optical fiber and coaxial cable. The optical fiber is laid to the community, even to the building or unit. [0003] In order to develop two-way services, radio and television stations must build a two-way broadband network or carry out two-way transformation on the exist...
