Abstract
The invention discloses an application method of a small switching matrix board based on a PC mainboard. The small switching matrix board based on a PC mainboard adopts a standard PCI interface commonly used by a PC mainboard, has no an independent case arranged on a traditional matrix, and needs no independent power supply additionally provided for the matrix per se. Meanwhile, a remote communication control line for connection is not needed any more, and when controlled by a PC, the connection can be realized by the PIC interface directly and can also be carried out through C-BUS or an external serial port. The invention can greatly reduce the extra space occupied by the traditional matrix, lower production and application costs and increase the flexibility and the usability of a system, not only provides convenience for the application of actual conditions such as televisionrelay, and the like, but also improves the working stability of the system. Therefore, the design way of the novel matrix is an economic, practical, convenient and stable design application.
Description
Technical field
The present invention relates to a kind of application process of matrix switcher.
Background technology
Matrix in the electron trade, full name is called matrix switcher, refers generally to have under the situation of multichannel input the output of multichannel to select, and forms matrix structure.Matrix switcher (hereinafter to be referred as matrix) is widely used in the link that fields such as TV station, broadcasting station, cable TV network need signal dispatching.Mainly be to be applied to large-screen splicing, video conference engineering, the occasion that audio frequency and video engineering, monitoring, broadcast control or the like need the multichannel audio-video frequency signal to be used alternatingly.
The scale of matrix differs, differs in size, and kind also is multifarious.But classical matrix all has a common characteristic, and that has adopted the standalone chassis structure exactly, has the independent current source power supply.In use, the matrix cabinet is fixed on the very big special instrument stand that takes up room.By various control mode, it is long-range such as control ports such as PCs to use connection to be connected to, thus the normal control of realization matrix, as shown in Figure 1.So just need take a large amount of additional spaces, expend a large amount of unnecessary resource and costs, simultaneously because the lifting of system cost causes the decline of the market competitiveness.And in the process of controlling by the control pair matrix, be subjected to the influence of mal-conditions such as on-the-spot electromagnetic signal, can have a strong impact on the control ability of system, reduce the reliability of system works, increased unnecessary puzzlement for TV station, broadcasting station etc. needs the user of high stability duty.The client moves difficulty when having other to need simultaneously, installs, dismantles loaded down with trivial details.So just press for a kind of novel gating matrix that not only can solve rig-site utilization but also can avoid above problem.
Summary of the invention
For solve that current matrix run in application process serious such as the space waste, extra cost is too high, system reliability is not high, move the loaded down with trivial details problem of installing, make that system works is more stable, efficient is higher, save more cost, make space resources obtain more effectively utilizing, the present invention has designed a kind of application process of the small-sized switching matrix integrated circuit board based on the PC mainboard.
Technical scheme of the present invention is: should adopt based on small-sized switching matrix integrated circuit board of PC mainboard the PC mainboard general standard pci interface, the standalone chassis that does not have classical matrix to carry, not needing additionally provides independent current source for matrix itself again.In using on-the-spot actual application, this kind of matrix integrated circuit board is installed on the mainboard of user's PC inside, the novel matrix integrated circuit board is powered by its mainboard by the PC internal electric source.Owing to the integrated circuit board of novel matrix has been installed to user's PC inside, so just saved classical matrix not only wasting space, but also cost of idleness and install and move loaded down with trivial details old-fashioned traditional cabinet, no longer needed the matrix cabinet is installed to and not only take up room but also load and unload difficulty, move on the inconvenient instrument stand.Owing to be to be installed to PC inside,, during PC control, both can directly realize simultaneously, also can be undertaken by C-BUS or external serial ports by pci interface so no longer need to use the telecommunication control line to connect.
Internally, the novel matrix integrated circuit board adopts the connection of the standard pci interface realization of PC mainboard to mainboard, the matrix integrated circuit board is inserted in the PCI slot of PC mainboard, realizes that by pci interface the PC mainboard is to the power supply of matrix integrated circuit board and the internal communication of PC mainboard and matrix.Externally, adopt the distant interface design of DVI-A, realize transmission and the access of REF external synchronization signal and the use of CBUS communication interface of signalling channel; Adopt the DB9 interface to satisfy the control needs of other PC simultaneously to matrix.During installation, the novel matrix integrated circuit board is installed to the PC mainboard by pci interface, matrix plate is fastened on the PC cabinet by metal baffle.The DB9 connector that has externally only kept the serial communication effect, and the DVI-A connector that plays signal connection effect, the input and output of matrix and CBUS communication, REF External Reference synchronizing signal all are to realize picking out by the DVI-A interface.The novel matrix integrated circuit board will be hidden in the cabinet of PC fully like this.Simultaneously because the influence of on-the-spot undesired signals such as above-mentioned electromagnetism to matrix stopped in the metallic shield effect of PC cabinet fully.When the user need control matrix by PC, both can carry out the exchange of communication data by the pci interface between mainboard and novel matrix integrated circuit board, can realize control by external serial line interface (DB9) again.
Beneficial effect of the present invention: can significantly reduce the shared exceptional space of classical matrix, reduce the cost of producing and using, the flexible availability that has increased system; Not only provided convenience, but also increased the job stability of system for the application of actual conditions such as television relay.So, we can say that the design of novel matrix is a kind of economic, practical, convenient, stable design application.
