一种交通监控光纤传输系统的设计与实现
|
摘要
本课题来源于哈尔滨锐科光电技术有限公司的项目—工业与交通用监控光端机。这是为克服具备同等功能的模拟光端机的缺陷而研制的项目，该项目要求用单纤对传一路视频信号和一路数据信号，同时要保证所研制的光端机具有较大的温差变化适应性。
虽然光纤专用通信系统已经得到了广泛的应用，但是它的应用也主要局限在模拟通信方式之下。模拟信号传输的最大缺点是图像质量的损伤是积累的，易产生失真。把模拟视频信号数字化后，可以解决上述模拟电视难于解决的问题，并产生令人鼓舞的新特性。但是在数字视频信号码流中存在随机的长连的“0”或“1”，不适合在光纤信道中传输。论文中详细论述了其原因并给出了切实可行的解决方法。
同时为了实现对现场摄像机的控制，还需回传一路数据信号。这一路数据信号的速率较低，不适合光纤信道传输，需要进行调制。
本文利用波分复用的方式实现了信号的对传，并设计出了具体的实现电路。最后对视频信号和数据信号的各项性能指标进行了严格的测试。通过实验，证明了方案的正确性和可行性。
This task comes from the plan of Harbin Rock Opto-electronic Technique
Co.,LTD-the digital optical transmitter and receiver used in industry and
traffic ,which has been studied in order to conquer the disadvantages of analog device .It must accurately transmit one video signal and reversely transmit one data signal in one fiber and work well when the temperate has changed greatly.
Although the special system of optical communication has already used widely ,its communication mode mainly depends on analog communication. The most disadvantage is that the damnification of image quality is accumulated and it will cause the distortion of video signal .When the video analog signal has been changed into digital signal ,it will not only conquer the problem that analog signal communication posses ,but also bring many new characters. There exist random long successive "0" or "1" in the code of image signal, which are not fit for the transmit of the optical channel. This paper makes a brief discussion on its reason and also gives out a practical method to solve the problem .When the temperate has changed greatly .The system will also transmit one reversal data signal in order to control the vidicon on site .Because the date rate is very low and can not fit for transmitter in optical channel ,it is necessary to modulate the signal.
The system makes use of the WDM mode to realize two reverse signals transmitter in one fiber and designs the practical circuit .At last ,the paper gives out the accurate capabilities that are attributed to the video signal and the data signal. The experiment proves that this method is both right and practical.
