可视化门禁系统的研究与实现
|
摘要
随着社会经济的发展,人民生活水平不断提高,传统的门禁系统渐渐退出历史舞台,新型门禁系统势必替代旧式门禁系统,成为门禁系统发展的‘风向标’,而可视化门禁系统便有这种‘风向标’的潜能。可视化门禁系统集红外线传感器、指纹采集系统、摄像装置及LED数码管等器件于一体,是一种红外热感指纹可视化门禁系统。它是在红外热感装置探测光线和温度信号变化的情况下,利用感光元件将信号传输到控制电路,从而控制LED感应灯。在有人靠近或远离本装置时,经红外热感装置将进行信号变化的传输,进而引起摄像装置的自动开闭,以实现可视化。
With the development of social economy, the people's living standard has been continuously improved. The traditional access control system gradually withdraws from the stage of history. The new access control system is bound to replace the old access control system and become the‘weathervane'of the access control system, The visual access control system then there is such a' weathervane' potential. Visual access control system integrates infrared sensors, fingerprint collection systems, camera devices, LED digital tubes and other devices into one, it is an infrared thermal fingerprint visual access control system. It is in the light and temperature change of the infrared thermal signal device, the photosensitive element transmits the signal to the control circuit, so as to control the LED induction lamp. When someone is near or away from the device,the infrared thermal device will transmit the signal changes, thereby causing automatic opening and closing the camera device, to achieve visualization.
