A kind of matrix of the utility model based on built-in intersection nuclear technology, to realize the switch unit of handoff functionality and make independently circuit-board card or connector integrated circuit board respectively as output unit, the input unit of output/input channel, mate the corresponding unit plate of pegging graft during use, can realize the matrix product of different scales, switching unlike signal.
This matrix comprises with motherboard communicates to connect and intersects nuclear plate specifically, and with intersect output board and the tablet that nuclear plate communicates to connect.Output board is provided with the output channel unit; Tablet is provided with the input channel unit.So-called channel unit had both comprised the circuit of realizing signal transfer functions, comprised the connector of realizing linkage function or the connector of other kinds again.
With reference to the intersection nuclear plate that specifies shown in Figure 2, comprise handover module, the tablet interface that is used to connect described tablet, the output board interface that is used to connect described output board of realizing the signal handoff functionality, the motherboard interface that is used to connect motherboard, and communicate by letter with handover module and to realize the CPU of switching controls; This CPU is by motherboard interface and the mutual control information of systems control division branch (seeing the systems control division branch among Fig. 1).Each several part specifically is described below:
Intersect and examine: the core of intersection nuclear technology, it mainly is made up of CPU and switching chip, also comprises the power supply that it is required certainly.Wherein, CPU is responsible for communicating with system control panel, and the work of chip is switched in control.The switching chip is used for finishing the switching of signal.Different switching chips can form different matrix-type, for example: if the switching chip of analog video can form the analog video switching matrix; If digital video is at a high speed switched chip, can form high definition, SD, DVI and HDMI switching matrix.And the switching chip of different scales also can form the matrix of different corresponding scales.
The tablet interface: be connected with tablet, tablet links to each other with the signal source of reality, for matrix is provided by the source that provides.As required and the type of switching chip can select different tablets, thereby form different matrixes.And one intersect nuclear and have a plurality of input interfaces usually, and the tablet that can insert varying number as required comes the gating matrix scale.
The output board interface: be connected with output board, output board links to each other with the signal receiver/terminal of reality, provides purpose for matrix switches.Equally can be as required and the different output board of type selecting that switches chip with tablet, thus different matrixes formed.And one intersect nuclear and have a plurality of output interfaces usually, and the output board that can insert varying number as required comes the gating matrix scale.
Motherboard interface: be connected with motherboard, intersect nuclear and the required power supply of input/output board and be connected with system control panel.
The concrete course of work is as follows:
As required corresponding intersection nuclear and input/output board are inserted.It is AD8113 (16X16), MT8816 (16X8) etc. that analog video switching intersection is endorsed with the switching chip of selecting for use, digital video switch to be intersected and to be endorsed with the switching chip of selecting for use to be M21111 (17X17), M21121 (34X34), VSC3139 (72X72), VSC3140 (144X144) etc., can to select according to required matrix size.Can select whether to place CPU on the input/output board as required, it mainly is some effective status data of being responsible for being provided with or reading signalling channel, and the interior CPU of nuclear of being convenient to intersect knows the residing state of passage immediately.The CPU in the nuclear of intersecting also has a main function exactly when controller or host computer switch software and carry out the signal switching, the data that it is sent here by system control panel are learnt concrete switching channel way, give then and switch the instruction of chip control corresponding, corresponding input channel and output channel connection will be realized switching thereby switch chip.Then, will with Signal Terminal that output board links to each other on show.For example: the digital video high definition switching matrix of a 32X32 if desired, except selecting a suitable cabinet correspondingly, can select for use and switch the built-in intersection nuclear that chip is M21121.If 16 passages are arranged on the every input/output board, so only need to select the input/output board of each two digital high-definition.So just can form a required digital video high definition switching matrix.On tablet, connect corresponding high-definition signal source, on output board, connect display terminal, such as oscilloscope, be connected with controller/switching software finish after, power on, just can switch normally.Have data communication from powering between controller/switching software and the system control panel, also be like this between system control panel and the intersection nuclear always.If first via signal source is switched on all No. 32 display terminals, on controller or switching software, to operate accordingly, system control panel will obtain switch data.System control panel can be given these data the CPU in the built-in intersection nuclear again.The nuclear that intersects obtains will operating the switching chip after these data, write some control commands and data to it, will be thereby switch chip according to the gained data with corresponding input and output channel connection, promptly import 1 passage and all be communicated with all 32 tunnel output channels, other input channel and this 32 tunnel output channel are all turn-offed.Like this, will show identical signal at all 32 display terminals that link to each other with output board, all be the data of signal source 1.Different switching chips, its control command and time sequential routine have difference slightly, but fairly large switching chip, general memory and the control register that oneself is all arranged.In most cases, all be earlier its control register to be provided with, and then write and the relevant data of passage switching.Common switching chip all has parallel and two kinds of control modes of serial, can select as the case may be.Comparatively speaking, parallel control speed can be fast, but control that needs and data wire can be more, and the speed of Serial Control can be slow, but required control and data wire can lack.Switching the job order that chip generally follows is the advanced horizontal reset in back that powers on, and allows it be in known state, writes its control register then, chip initiation setting just, afterwards just can write data.Also just having finished corresponding signal after having write switches.
Some are used for the chip that high definition is switched, and as M21111 (17X17), M21121 (34X34), VSC3139 (72X72), VSC3140 (144X144), their bandwidth is all very high, can be used for the switching of DVI signal simultaneously and needn't change and intersect nuclear.Because the DVI interface has four road signals, they are one, so can not switch like that with high-definition signal.So need input/output board to give to intersect and examine the type that a signal is determined switching signal, this can accomplish fully, so only need to change input/output board just passable if want that a high definition matrix is become the DVI matrix.The DVI tablet can be connected to main frame or other signal source equipment of DVI interface, and output board can be connected to the display terminal of DVI interface, and as display, television set etc., this is a kind of matrix product that development space and market are arranged very much.Its also compatible SD signal switches, and also being only needs the replacing input/output board just passable.
The above; it only is the preferable embodiment of the utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection range of the present utility model.
