In addition, the spectral camera 2 is used for acquiring light of a specific wavelength, and is also used for imaging according to the acquired light of a specific wavelength, and uploading the resulting image to the main control device 1 . At the same time, the main control device is used to judge whether the image is consistent with the pre-stored standard image of the reflective coating 31 according to the image uploaded by the spectrum camera 2, and unlock the door after the judgment is consistent.

It is not difficult to find out from the above content that since the entire system only needs to pre-store a standard image of the reflective coating 31 in the main control device to realize identity recognition, there is no need to establish an additional large database to store the identity information of relevant personnel , thereby reducing the cost of the entire system. In addition, when performing identity recognition, the entire system obtains light of a specific wavelength through the spectral camera 2 for imaging, and the main control device compares the image formed by the spectral camera 2 with the internal pre-stored standard image, and judges whether the image is consistent with Whether the standard image of the pre-stored reflective coating 31 is consistent, and the door lock is opened after it is determined to be consistent. Since the spectrum camera 2 can only image light of a specific wavelength, the intensity of the infrared light emitted by the infrared light emitting device 1 is the same as The wavelength of light reflected by the reflective coating 31 needs to be pre-matched in the system, so that the access control card is not easy to be cracked, and the security of the entire system is improved. At the same time, since the infrared light emitting device and the spectrum camera are only opened by the main control device after the signal receiving module receives the radio frequency signal sent by the signal transmitting module, in general, the infrared light emitting device 1 and the spectrum camera 2 are both In the closed state, it can effectively reduce the power consumption of the whole system.
