家用视频监控门禁系统自动采集存储设计与实现

Designation and application of automatic capture and storage in domestic video monitored control system

利用红外热释电传感器及BISS0001专用信号处理芯片设计出较理想的自动控制系统,用于控制CCD进行视频采集,实现了对人体目标进行监控、视频采集和存储。设计过程中,通过调整电路封锁控制时间Ti和延时控制时间Tx,实现了CCD视频采集器在一次触动过程中进行图像的3次连拍和存储;同时,利用光敏电阻对环境光照度检测来辅助采集系统的补光照明,实现了在低照度条件下,采集系统的LED灯和图像采集同时同步触发,达到了理想效果,其较强的实用性和高的性价比能很好地应用于家庭式或小型企业门禁视频监控管理。

A automatic control system is designed based on pyroelectric infrared radial sensor and BISS0001 signal processing slug,with which CCD image sensor can monitor human target,capture videos and storage images.By adjusting the circuit of lockout time Ti and delayed time Tx,3-times serialograph and images storage are realized with CCD image sensor in one triggering.In addition,when the CCD video monitored control system is working in insufficient illuminance,the high-light LED can automatic be unblocked synchronous based on photoresistance compensator.With its good practicabilities and low cost,it can be widespread used in housing estate and minitype enterprise practicability.
