Abstract
The utility model discloses a two -wire system digit intercom system, including IP center management machine, IP gate host computer, the plural number digital floor distributor of platform and the indoor extension of plural number platform IP, IP gate host computer passes through the net twine with IP center management machine and digital floor distributor respectively and is connected, digit floor distributor is connected with the indoor extension of plural number platform IP through two heart yearns or telephone line, and digital floor distributor meets DC power supply, simultaneous transmission communication signal is supplied power through two heart yearns or telephone line to digit floor distributor to the indoor extension of IP. The utility model discloses numeral intercom system simple structure, do not need additionally to lay the numeral and talkback the cable and can accomplish whole floor numeral and talkback to upgrade and transform. Old cable can utilize again, and construction convenience can reduce the transformation cost.
Description
[technical field]
This utility model relates to building conversational system, particularly relates to a kind of two-wire system digital intecommunication system.
[background technology]
Building conversational system is a door bell and button system, i.e. realize in multilamellar or skyscraper visitor, resident family and
Building's management center communicates with each other, carries out communication for information and realize the management that Vomitory safe to community controls
System.
Client can be called resident family by the main frame before cell gate downstairs and talked with it easily, and is not having
Call property management personnel in the case of having band key, assist to open unit lock, and resident family the most also may be used
With the keying of control unit door, resident family can operate indoor unit and carry out calling property management personnel, doorway master
Machine this can also receive resident family's alarm signal at any time and pass to host notification community guard on duty, system is not only
Enhance high residential building safeguarding work, and greatly facilitate resident family, reduce many unnecessary upper and lower
Building bothers, and links up more convenient and quicker safe and reliable.
The analog-interphone of the intercom system employing analog communication techniques that old community is traditional, analog-interphone
Voice, signaling and signal are debugged on transmitter receiver carrier frequency in continuous wave mode, and the one processed through amplification etc.
Communication mode.The signal such as image, voice is the most unstable, is easily affected by other factor.And connecting line is divided into power supply
Line and holding wire, holding wire is usually 6 heart yearns.Digital intercom is the most ripe, the most generally carries out numeral right
Say in system upgrade transformation, need rewiring, constructional difficulties between floor light current well, and waste resource.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of simple in construction, line resource can be again sharp
With, it is not necessary to extra laying digital intercom cable, the two-wire system digital intecommunication system that improvement cost is relatively low.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is, a kind of two-wire system numeral
Intercom system, including IP centre management machine, IP doorway main frame, plural number number of units word floor distributor and plural number platform
IP indoor unit, IP doorway main frame is connected by netting twine with IP centre management machine and numeral floor distributor respectively
Connect；Numeral floor distributor is connected with plural number platform IP indoor unit by two heart yearns or telephone wire, numeral floor
Allotter connects DC source；Numeral floor distributor is powered by two heart yearns or phone alignment IP indoor unit,
Transmit signal of communication simultaneously.
Above-described two-wire system digital intecommunication system, plural number platform floor distributor is concatenated by netting twine.
Above-described two-wire system digital intecommunication system, described netting twine is twisted-pair feeder or coaxial cable.
Above-described two-wire system digital intecommunication system, described signal of communication includes that video signal, audio frequency are believed
Number and control signal.
Above-described two-wire system digital intecommunication system, described IP indoor unit is that digital visual intercommunication is indoor
Machine, described IP doorway main frame is digital visual intercom machine.
This utility model digital intecommunication system simple in construction, need not additionally lay digital intercom cable can be complete
Become entire building layer digital intercommunication upgrading.Old cable can re-use, easy construction, can reduce and change
Cause this.
[accompanying drawing explanation]
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the theory diagram of this utility model embodiment two-wire system digital intecommunication system.
In figure, 1.--netting twine；2.--RVV two heart yearn or telephone wire.
[detailed description of the invention]
Structure and the principle of this utility model embodiment two-wire system digital intecommunication system are as it is shown in figure 1, include prison
Control center IP supervisor, IP doorway main frame, number that (digital visual intercom machine) is identical with floor quantity
Word floor distributor and with resident family's quantity identical IP indoor unit (digital visual intercommunication indoor set).
Surveillance center's IP supervisor is connected by netting twine with the IP doorway main frame in building, transmits video, audio frequency
And control signal.
IP doorway main frame is connected by netting twine with floor distributor, and netting twine can be twisted-pair feeder or coaxial cable；
Floor distributor works in Width funtion, connects DC18V-36V DC source.The LAN interface of IP doorway main frame leads to
Cross netting twine and connect the floor distributor of each floor.Each floor distributor has 8 tunnel two heart yearn interfaces, can connect
Entering 8 road IP indoor units, export 8 road DC12V power supplys simultaneously, power supply is transmitted with signal one line.
IP indoor unit is connected by RVV two heart yearn or telephone wire with floor distributor.Pass with ICP/IP protocol
Defeated video, audio frequency and control signal.IP indoor unit has 2 core Data Input Interfaces, and 2 core data are defeated
Incoming interface is simultaneously as power input interface.Power supply and the transmission of data same interface.
Two-wire system digital intecommunication system is using power line as information and the dual-purpose transport vehicle of power supply, the most slotting
I.e. use.In the digital intercom upgrading of old community, it is not necessary to rewiring.
