Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
The human-computer interface system that has video monitoring described in the utility model as shown in Figure 2, comprises system processing unit, is used for operation system and utilization software; Graphics Processing Unit (GPU) is used for video image and configuration picture are synthesized processing; With the graphics processing unit that Graphics Processing Unit (GPU) is connected, be used to finish the synthetic and individual operation of multi-path video data; Graphics processing unit is connected in the I2C mode with system processing unit simultaneously, finishes various functions with the instruction of accepting system processing unit; And with the display unit of Graphics Processing Unit (GPU), i.e. LCD MODULE.
As shown in Figure 3, be the scheme arrangement figure of the utility model preferred embodiment.This scheme partly is a core with U4, U5, U7, U8, assists and partly realizes the purpose of this utility model with U1, U2, U3, U6.
Concrete, U4 is the system processing unit (CPU) in this programme, uses the Xscale framework of compatible ARM instruction set, dominant frequency 400MHz is used for operation system and utilization software.Because native system adopts the (SuSE) Linux OS of increasing income, use the gui software of independent development, this has certain requirement to cpu performance.
U1 is SRAM, is mainly used in storage user formulation data, and by the back-up source power supply, data are not lost inside guaranteeing after the power down.
U2 is SDRAM, and the operation of main program at ordinary times all here.
The U3 system storage is mainly used in and is depositing the bootloader of system, linux kernel, GUI and various driver.
U5 is a graphic process unit, it mainly acts on is that display graphics is done acceleration conversion on the hardware, handle the vision signal of U8 input, and vision signal is added on the raw frames, the register space of itself, video memory spatial mappings simultaneously also can be as coprocessor work to the memory space of U4.By 32 position datawires, 25 bit address lines connect between it and the host CPU, and U4 can read and write inner all registers of U5 and memory space.U5 also carries a lcd controller simultaneously.
U6 is system's video memory, is mainly used in to deposit video data, comprises picture bottom data and video data.
U7 video image memory is mainly used in the video image of depositing in the processing procedure.
The U8 graphics processing unit adopts the chip with the decoding of four-way high-quality video, and its inner integrated 4 tunnel 10 analog to digital converters (ADC) are mainly used in and finish the synthetic of 4 road video images, functions such as convergent-divergent.Mainly there are the exchange of video data in U5 and U8.U5 carries out convergent-divergent to it then as required with the video data of BT601 form reception from U8, schemes the stacked processing that adds.
Shown in Figure 4 is the schematic circuit diagram of the utility model preferred embodiment.The system works principle of Fig. 3, the utility model preferred embodiment shown in Figure 4 is as follows:
After system start-up, U4 carries out initialization by the I2C bus to U8, make it can receive 4 road Phase Alternation Line systems or TSC-system CVBS (composite video) signal, U8 is respectively to carrying out 4 road or 3 road or 2 tunnel synthetic one tunnel video signal flows that meet the ITU.BT601 agreement on demand after 4 road analog video signal AD conversion, also can be directly one road gating wherein be transferred to U5.When using multichannel synthetic, the value of can be as required revising the U8 particular register by the I2C bus is adjusted position, size and the display mode (such as the vertical mirror demonstration etc.) of each road video image.
After U5 receives vision signal from U8, can adjust its different display positions on LCD (LCD) as required and show size, also can intercept current video frame as required, the quantity of preserving frame of video is relevant with the Installed System Memory size.
In the utility model embodiment, U8 part periphery mainly comprises the input of 4 road analog videos.Show as Fig. 5, composite video signal (CVBS) by electric resistance partial pressure after capacitor C coupling be input in the video frequency processing chip.For reliability is provided, reduce interference on the video data line to the damage of chip, placed an analog video signal privacy protection device D in this programme in video input, every road.
Because general required on the industrial man-machine interface of video monitoring needs to watch in real time a state of running status, product line states and the surrounding environment of equipment part, can realize that the storage of single-frame images gets final product.The utility model is integrated into video module in the man-machine interface, and can receive nearly four tunnel analog video input, has satisfied this demand in market fully.
More than be preferred forms of the present utility model, according to the disclosed content of the utility model, some identical, replacement schemes that those of ordinary skill in the art can expect apparently all should fall into protection range of the present utility model.
