In the matrix switching system, a four-line resistive touch screen is adopted, so that the control interface is beautiful and elegant, and more luxuriant; the graphical control interface enables man-machine interaction to be more friendly, visual and simple; the interface is flexible and can be changed according to preferences of users; and high-performance high-bandwidth and high-speed switching chips are adopted for switching, so that optional switching between AV input and output signals can be realized.
Description
Technical field
The utility model relates to a kind of matrix switch system, especially a kind of matrix switch system that is used for the switching of AV signal.
Background technology
AV series matrix switch system is to switch the high-performance intelligence matrix switch equipment that designs for the demonstration of sound, vision signal specially; Be used for the synchronous or asynchronous arbitrary passage that switches to the audio frequency and video output channel of each road audio frequency and video input signal, and independently of one another between output channel.Briefly; Exactly can be with any display that is shown to any prior appointment in the multichannel input signal of coming in; " matrix " itself is a mathematical concept, and it is the abbreviation of an electronic product in electron trade, and its full name is called " matrix switch system "." matrix " two words in the matrix switch system are matrix concept of having quoted in the higher mathematics linear algebra.In this electronic product of matrix switch system, refer generally under the situation of multichannel input, have the output of multichannel to select, form matrix structure.In producing and living, numerous working people's wisdom is powerful, so it has just been done " matrix " by abbreviation.Generally speaking, matrix switch system is one type of equipment that switches the multiple signals input and output.Popular says; Matrix switch system is exactly to be that one or more audio-video signal is transferred to one or more display device respectively in fact; As: the two computers main frame is wanted a shared display, and matrix switch system can switch to the content on the two computers main frame arbitrarily on same or a plurality of displays.Yet the gorgeous inadequately exquisiteness of the output screen color of common matrix switch controller, interface are abundant inadequately, and be simultaneously also elegant in appearance inadequately.
Summary of the invention
The utility model is in order to solve defective and the deficiency that above-mentioned prior art exists; Provide a kind of output screen exquisiteness lucuriant in design, elegant in appearance, interface abundant, can realize between the AV input/output signal any switching be used for the matrix switch system that the AV signal switches.
The technical scheme of the utility model: a kind of matrix switch system that is used for the switching of AV signal; It comprises matrix mainboard, control keypad and power panel; Control keypad and power panel are connected to the matrix mainboard respectively, and said matrix mainboard is provided with AV input/output interface and serial control interface.
Preferably, said control keypad is the four-wire ohm touch-screen.
Preferably, said AV input/output interface and serial control interface are standard RCA joint, and said AV input/output interface comprises AV video input/output interface and AV audio frequency input/output interface.
The utility model adopts the four-wire ohm touch-screen; Make that the control beautiful interface is generous and abundanter; More the close friend is more intuitively simpler in the man-machine interaction that graphically makes at control interface; And flexible interface can be changed according to user preferences, switches the switching chip that adopts high-performance high bandwidth and high speed degree to switch, and can realize any switching between the AV input/output signal.
Description of drawings
Fig. 1 is the theory diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed explanation, but be not restriction the utility model protection range.
As shown in Figure 1; A kind of matrix switch system that is used for the switching of AV signal; Comprise matrix mainboard, control keypad and power panel, control keypad and power panel are connected to the matrix mainboard respectively, and said matrix mainboard is provided with AV input/output interface and serial control interface.The control keypad is the four-wire ohm touch-screen.The matrix mainboard is provided with AV input/output interface and serial control interface, and AV input/output interface and serial control interface are standard RCA joint, and the AV input/output interface comprises AV video input/output interface and AV audio frequency input/output interface.
The product of the utility model is mainly used in occasions such as radio and television engineering, the multimedia conferencing Room, large scale display engineering, television teaching, command and control center.Product has functions such as outage scene protection, audio-visual synchronization or separation switching, and possesses the RS232 communication interface, can make things convenient for and PC, and remote control system or various far-end control appliance (like PC, central control system etc.) are used.The AV matrix has synchronous and asynchronous two kinds of working methods.System works can be carried out audio-visual synchronization and switch when the method for synchronization; System works can be carried out Voice & Video and switch respectively when asynchronous system.All can revise system operating mode through serial ports and button.System when the synchronous working mode is switched, is main with the video channel state by asynchronous, and voice-grade channel switches with video channel synchronously.
The interface of the utility model is divided into video input, output interface, audio frequency (left and right sound channels) input output interface, interface is a standard RCA joint, can be connected with the audio frequency and video lead-out terminal of various sound equipments or multimedia equipment.The utility model provides standard RS-232 communication interface, and it is various to allow the user to use, and far-end control appliance (like PC, central control system etc.) is controlled the AV matrix system.
The front panel of the utility model adopts 4.3 cun very color touch-screens, adopts the ARM9 framework, the four-wire ohm touch-screen; Pixel esolving degree 480X272, exquisiteness lucuriant in design, elegant in appearance; The interface is abundanter, and more the close friend is more intuitively simpler in the man-machine interaction that graphically makes at control interface, and flexible interface can be changed according to user preferences; Switch the switching chip that adopts high-performance high bandwidth and high speed degree to switch, realize any switching between the AV input/output signal.
The utility model has realized that mainly the matrix switch system of AV signal lays the foundation for realizing radio and television engineering, the multimedia conferencing Room, large scale display engineering, television teaching later on, accelerates the pace of construction of social informatization.
