Publication No. CN2364647Y's《CPU building talkback automatic switch-boards》, it is noted that host, extension set and its line and power supply, main,
Extension set includes master, extension set, control circuit, power supply and line, it is characterised in that host is with whole extension sets only with one
Quad is connected in parallel, and host computer control circuit includes microcontroller IC22051, double-audible frequency device IC38870 and control relay
Switching tube N1, N2 of device J1, J2 action；Extension set control circuit includes microcontroller IC2 ' 1051, double-audible frequency device IC3 ' 8870
And switching tube N1 ', the N2 ' of control relay J1 ', loudspeaker S1 action.In practice, this system indoor unit has necessarily
Standby electric current, such as 150mA powered, about 1.8W using 12V.The unit of one building talkback, such as 30 layers, every layer 4
Family, a unit totally 120 family, total standby current are 150mA × 120 families=18000mA, that is, the electric current of 18A, are considered
To the pressure drop of low-voltage power supply and reserved, the power supply power-supply service of a unit will more than 30A.Since total current is bigger, just
Take into full account the thickness of power cord, or subregion power supply, for example every 5 layers put a power supply.
The content of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of electricity-saving type building conversational system.
Technical solution is used by the utility model solves its technical problem：
A kind of electricity-saving type building conversational system, including doorway host, decoder, indoor unit and power supply composition, the solution
Code device is built-in with the mainboard being connected with power supply, and microcontroller is provided with the mainboard of the decoder, and the indoor unit passes through super
Five class cables are connected with decoder.
As a preference, the power supply switching of the extension set is controlled by decoder, is provided with the decoder
Power supply switch circuit.
As a preference, liquid crystal display, loudspeaker, microphone and button are provided with the extension set.
As a preference, the decoder includes the communication interface of doorway host and connecing for control indoor unit
Mouthful.
As a preference, RS232 communicating circuits, amplifying circuit are additionally provided with the mainboard of the decoder.
The beneficial effects of the utility model are：The system does not have by the optimization design powered to extension set when extension set is standby
Any electric current, greatly reduces the conduction time of extension set, not only extend product service life, while also save mass energy and
Fund, meets current energy-saving and environment-friendly trend.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the utility model.
Embodiment
It is with reference to the accompanying drawings and embodiments, right in order to which the object, technical solution and advantage of the application are more clearly understood
The utility model is further elaborated.For the thorough explanation present invention, it is special that some can be related in following description
Determine details.And in these no specific details, the invention can still be realized, i.e., the technical staff in fields uses this
These of place describe and state that the others skilled in the art into fields can more effectively introduce their work essence.
With reference to Fig. 1, a kind of electricity-saving type building conversational system, including doorway host 1, decoder 2, indoor unit 3 and power supply 4
Composition, the decoder 2 are built-in with the mainboard 5 being connected with power supply 4, microcontroller 51 are provided with the mainboard 5 of the decoder 2,
The indoor unit 3 is connected by surpassing five class cables with decoder 2, i.e., the microcontroller 31 of original indoor unit 3 moves on to decoder 2
On, indoor unit 3 does not set microcontroller 31.Exgt Bat extension battery switching circuit 21 is provided with the decoder 2, in control room points
The power supply of machine 3, wherein indoor unit 3 are powered by decoder.Liquid crystal display, loudspeaker, Mike are provided with the indoor unit 3
Wind and button, decoder 2 is by the failure of current of indoor unit 3 when standby, so the electric current of indoor unit 3 is equal to 0 when standby, only
Have when being connected to the calling that doorway host 1 comes, 2 ability of decoder is just powered by the power on of called extension set, extension set.
The decoder 2 includes the interface of doorway host communication interface and control extensions.On the mainboard 4 of the decoder
RS232 communicating circuits 53, amplifying circuit 54 are additionally provided with, wherein RS232 communicating circuits 53 are responsible for and doorway host 1 and central tube
Communication process between reason machine, with 54 cooperating of amplifying circuit.
It was verified that the system has good economic benefit, calculated with a certain 1000 family of cell, during unused this technology
The standby electricity consumption of indoor unit in 1 year is：When 1.8W × 24 are small × watt-hour=15768 degree of 365 days × 1000 family=15768000,
15768 degree × 0.6 yuan /=9460 yuan of degree, after having used this technology, due to the standby zero current of extension set, 9460 yuan will be saved in 1 year,
About 10,000 yuan.
