The technical advantage of the utility model: with the microcontroller is the embedded system of core, has characteristics such as expense is little, size is little, function is strong.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.
Description of drawings
Fig. 1 is the present embodiment entire block diagram.
Fig. 2 is that the present embodiment microprocessor is connected scheme drawing with video module.
Fig. 3 is that the present embodiment microprocessor is connected scheme drawing with mixed-media network modules mixed-media.
Fig. 4 is that the present embodiment microprocessor is connected scheme drawing with FLASH ROM.
Fig. 5 is a present embodiment video acquisition order drawing.
Fig. 6 is present embodiment elevator monitoring signal procedure figure.
The specific embodiment
With reference to shown in Figure 1.The utility model has adopted with treater as CPU, and the function of CPU comprises and realizes video data acquiring control, video data packing, the transmission of wireless module.
Video module, memory module, wireless network module all link to each other with treater.
Fig. 2 is the junction circuit of present embodiment video module and microprocessor.Because what adopt is 8-bit ITU-R BT.656 output, therefore only needs 8 position datawires and a pixel clock.TVP5150 controls through iic bus, and tone, contrast ratio, brightness, degree of saturation specific humidity and acutance etc. can be set.Owing to be high-frequency signal, the disturbance rejection of circuit there is certain requirement.
Fig. 3 is that the present embodiment microprocessor is connected scheme drawing with mixed-media network modules mixed-media.Being connected through interfaces such as MII, RMII of mac controller and PHY realizes.In IEEE802 consensus standard series, data link layer comprises LLC and MAC two sub-layer.Wherein MAC is responsible for accomplishing the envelope of Frame
Dress, deblocking, transmission and receiving function.The structure of Physical layer PHY has certain difference along with the difference of transfer rate.MII is the interface that connects data link layer and Physical layer.According to agreement, the function that requires the MII interface to have has: the read/write clock of data and frame separator is synchronous; Independently read/write data passage is provided; For MAC layer and PHY layer provide corresponding management and support full-duplex mode, for networks such as 10BaseTest, from the output of ethernet PHY chip is exactly to transmit required differential signal.But, also needing a network isolation transformer, network isolation transformer can play effects such as suppressing common mode interference, isolation circuit and impedance match.
Fig. 4 is a present embodiment NAND FLASH module and the scheme drawing that is connected of microprocessor.NAND FLASH is connected on 6410 the Xm0 bus, and data line is 8, uses Xm0DATA0-Xm0DATA7, because NAND is the non-linearity addressing, so without the link address line.What MLC type FLASH adopted is the 3.3V power supply, receives VDDIO.FALE is the address enable end of NAND FLASH, and when this signal when being high, what expression was sent is the address, and this moment, NAND FLASH sent the location through N time, and here N time is the 1Byte of the big or small byte number of the total space of NAND FLASH/at every turn.What FCLE represented to send is order, for example Erase order.FREn and FWEn connect the read-write of NAND.FRnB is the busy judgement of NAND FLASH.
Fig. 5 is a present embodiment video acquisition program flow diagram, and at first the ARM microprocessor is configured through IIC TVP5150, and requests to be collected such as success back begin to gather video information after the request comes.
