Abstract
The utility model discloses a building talkback network coupler with the communication of analog and digit. The building talkback network coupler comprises a digital signal processor connected with a local area network and a digital to analog converter connected with an analog control system, wherein the digital signal processor is connected with the digital to analog converter; the digital to analog converter receives analog signals of sound and video of the analog control system, converts the analog signals into digital signals and inputs the digital signals into the digital signal processor; and the digital signal processor receives a digital signal of the local area network and processes the digital signal thereof, and the processed digital signal is converted into analog sound and video and can be input to the analog control system by the digital to analog converter. With the technical scheme, the network coupler can realize the mixed use of an indoor extension analog system and a digital system, so as to bring more convenience for a user.
Description
Technical field
The utility model relates to a kind of net connection device, in particular the building talkback net connection device that simulation and digital indoor unit can be public in building conversational system.
Background technology
Building conversational system can be divided into analog equipment and digital product according to the technology difference that realizes, analog equipment is to adopt 485 bus modes to realize, digital product is to adopt ICP/IP protocol netting twine transmission means to realize, analog equipment and digital product cannot be used with in a system in principle, especially indoor unit, all have the limited problem of product category for analogue system and digital system like this, otherwise the cost input that will increase identical style type enlarges product category.
The utility model content
At the deficiencies in the prior art, the utility model provides a kind of simulation and building talkback net connection device of digital communication of having concurrently, and it can realize that indoor unit analogue system and digital system use with.
Have the building talkback net connection device of simulation and digital communication concurrently, it is characterized in that: comprise a digital signal processor that is connected with local area network (LAN) and the digital to analog converter that is connected with analog control system, digital signal processor and digital to analog converter communicate to connect.
The analog signal conversion that digital to analog converter receives the Voice ﹠ Video of analog control system becomes digital signal to input to digital signal processor.
Digital signal processor receives local netting index word signal processing, and the Voice ﹠ Video that converts simulation through digital to analog converter to is transported to analog control system.
Adopt the network connector after the above-mentioned technical scheme, it can realize using with of indoor unit analogue system and digital system, brings more convenience to the user.
