Portable wireless network road traffic monitoring instrument

The utility model discloses a portable wireless network road traffic monitoring instrument, comprising a pick-up head used to collect image, a video collect chip SAA7114, a memorizer SRAM, a DSP chip and a programmable logic device CPLD (FLEX10K50). The signal line of the pick-up head is connected with the input of the video collect chip SAA7114 and the output programmable logic device CPLD of the video collect chip. The CPLD is connected with the memorizer SRAM and the control end of the DSP chip. The bus line of the DSP chip is simultaneously connected with the bus line of the computer. The utility model uses the high-speed DSP as the center processor, bases on the video image processing technique and the pattern recognition theory, together with the advanced wavelet nerual network technique to recognize and track the moving target. Thus the utility model has the advantages of little operation, good real-time performance, high precision, etc.
