本文实现了光缆监测站自动监测终端设备的设计方案，通过嵌入式硬件系统和软件的协同工作，该监测设备能够对通信光缆进行在线实时监测，并且能够实时探测到通信光缆的故障点，方便了通信光缆的维护工作。该系统在业务板卡的设计，以及CAN控制通信总线的使用都增强了设备的兼容性和系统的可扩展性，并且增加了环境监测单元来自动调节环境温度，以保证系统安全可靠运行。(This automatic monitoring stations to achieve a fiber optic terminal equipment design, through the embedded hardware systems and software work together, the monitoring device can communicate on-line real-time monitoring of fiber optic cable and communication cable in real time to detect the point of failure, to facilitate the communication cable maintenance. The system is in the business card design, and the use of CAN bus control communication devices have enhanced compatibility and system scalability, and increased environmental monitoring unit to automatically adjust the temperature to ensure the system safe and reliable operation.)

说明：  Owing to the broad application value of audio watermarking in remote transmission and mobile extraction, it is very important to study watermarking approaches against A/D and D/A conversion. Based on wavelet decomposition and cepstrum technology, an audio watermarking algorithm is proposed where the low-frequency wavelet coefficients are chosen for cepstrum transforming. Then, the obtained cepstrum data shows stable for watermark hiding by the methods of edging data cutting and statistical mean modification. The synchronization is not required in the algorithm. Experimental results show that the proposed algorithm can resist on the attack of A/D and D/A successfully with features of large capacity and zero bit error. It will be helpful for the mobile audio in secure broadcast and management in the
