摘要
针对采用"一线通"等外置设备进行多个监控信号共缆传输的实际应用过程中存在信号易受干扰、隐蔽性差、施工难度大、调试复杂等问题,利用OFDM、FDM和电路微型化等技术开发核心芯片,将其嵌入普通监控摄像机后,可使监控摄像机的安防监控系统抗干扰能力更强、安装更简单、隐蔽性更强、维护成本更低。
In view of the problems encountered when using external device like ＂one line control＂ to make multiple monitoring signals transfer in one line that the signal may be interfered easily and has poor concealing ability,the construction difficulty is big and the system is not easily adjusted,the author uses the technology of OFDM,the technology of FDM and miniature circuit to develop different core chips that embedded in normal monitoring video camera.The advantages are making the system of security-monitoringhave strong anti-interference ability,concealing ability, lower maintenance cost and be installed more easily.
