Description

A kind of emergent broadcast multi-channel adaptation device

Technical field

The utility model relates to broadcaster technical field, be specifically related to a kind of emergent broadcast multi-channel adaptation device.

Background technology

High speed development along with national economy, outlying district, minority area broadcast are covered work and increasingly pay attention to by Party and government, local governments at all levels wish that the demand being carried out public opinion by radio broadcasting is particularly urgent, the effect that particularly broadcast system plays in accident highlights its importance day by day, and existing broadcast covers system can't be fully solved the particular/special requirement of emergent broadcast. Each province and district city, county carried out the construction of " village of village rings " engineering on a grand scale in recent years, the problem solving remote villages broadcast listening well, it is that villagers' committee notifies to provide platform immediately by " village of village ring " system simultaneously, but for " village of village rings " emergent broadcast, the content broadcasted is needed to may be from frequency modulation broadcasting, medium wave broadcast, it is also likely to be the sound accompaniment of TV, it is also possible that ip voice, in emergent broadcast, the priority of signaling conventions also has difference, so the emergent broadcast multi-channel adaptation device for emergent broadcast feature arises at the historic moment.

Utility model content

For the deficiency existed in prior art, this utility model purpose is to be in that to provide a kind of emergent broadcast multi-channel adaptation device, simple in construction, reasonable in design, achieve a set of broadcasting equipment adaptation to plurality of information resources, reduce repeated construction, reduce cost of equipment maintenance, practical, it is easy to promote the use of.

To achieve these goals, this utility model is to realize by the following technical solutions: a kind of emergent broadcast multi-channel adaptation device, including ATCA structure cabinet, cabinet backplate, board socket, two-supply circuit, bus backplane and CPCI55 socket, ATCA structure cabinet inside is provided with two-supply circuit and bus backplane, and the cabinet backplate of ATCA structure cabinet is provided with four identical board sockets of size dimension.

As preferably, described bus backplane is provided with four CPCI55 sockets, CPCI55 socket is connected with system bus respectively, and described system bus includes �� and 12V main power supply line, Ethernet ETH holding wire, RS485 control bus, AES/EBU audio-frequency bus and analogue audio frequency bus.

As preferably, the accommodation of four board sockets on described cabinet backplate is of a size of 138.2mm*165.5mm.

The beneficial effects of the utility model: (1) is at village level emergency broadcase system, it is achieved that a set of broadcasting equipment adaptation to plurality of information resources;

(2) one machines can the board of integrated multiple difference in functionalitys, integrate the plurality of information resources of frequency modulation broadcasting, medium wave broadcast, television field frame and ip voice different priorities, reduce repeated construction, reduce cost of equipment maintenance;

(3) two-supply circuit works simultaneously, backups each other, it is ensured that emergency broadcase system work is uninterrupted, reliable and stable.

Accompanying drawing explanation

This utility model is described in detail below in conjunction with the drawings and specific embodiments;

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of this utility model bus backplane.

Detailed description of the invention

For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with detailed description of the invention, this utility model is expanded on further.

With reference to Fig. 1-2, this detailed description of the invention is by the following technical solutions: a kind of emergent broadcast multi-channel adaptation device, including ATCA structure cabinet 101, it is installed on the cabinet backplate 102 within ATCA structure cabinet 101, board socket 103, two-supply circuit 104, it is installed on the bus backplane 105 within described ATCA structure cabinet 101 and CPCI55 socket 106, two-supply circuit 104 works simultaneously, backup each other, ensure that emergency broadcase system work is uninterrupted, the cabinet backplate 102 of ATCA structure cabinet 101 is provided with four identical board sockets 103 of size dimension, bus backplane 105 is provided with four CPCI55 sockets 106.

It should be noted that described CPCI55 socket 106 is connected with system bus 107 respectively, described system bus 107 includes �� and 12V main power supply line, Ethernet ETH holding wire, RS485 control bus, AES/EBU audio-frequency bus and analogue audio frequency bus.

The accommodation of described four board sockets 103 is of a size of the board of 138.2mm*165.5mm, insert the audio detection including one or more on the board of board socket 103 and process circuit and embedded MCU, on plate, the software system of MCU adopts embedded OS WINCE or LINUX, communication interface has the form such as Ethernet interface and RS485, frequency modulation, medium wave, one or more voice signal input port of television field frame or ip voice, various board buses are consistent, can be inserted into any board socket 103 of ATCA structure cabinet 101, board is powered and is provided by EBI is unified.

The core of this detailed description of the invention is to integrate the system bus of Ethernet ETH holding wire, RS485 control bus, AES/EBU audio-frequency bus and analogue audio frequency bus, solve the problem that conventional apparatus is difficult to pool together frequency modulation broadcasting, medium wave broadcast, television field frame and ip voice multiple voice information source, according to priority automatically select output, its advantage is at village level emergency broadcase system, it is achieved that a set of broadcasting equipment adaptation to plurality of information resources.

This detailed description of the invention adopts standardized EBI and power supply, consistent board size, every kind of board can have one or more audio sources input and monitoring to process circuit, each board passes through bus interactive information, main control unit is with analog/digital audio output interface, output is selected by the priority in each board audio sources signaling, one machine can the board of integrated multiple difference in functionalitys, collection frequency modulation broadcasting, medium wave broadcast, the plurality of information resources of television field frame and ip voice different priorities is integrated, not only reduce repeated construction, it is greatly reduced cost of equipment maintenance, there is wide market application foreground.

Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described. Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.
