Problems solved by technology

[0002] With the continuous improvement of people's living standards, intelligent information identification technology has been widely used. At present, for the identification of intelligent information, when 30-300KHZ low-frequency signals are used for positioning key activation and encrypted information identification, it is easy for information mobile terminals to send encrypted information. The frequency of information occurrence is too low, and the verification and transmission time is too long, resulting in poor signal transmission. Therefore, the existing COSCO (above 1 meter) distance intelligent information identification technology sends information using UHF signals of 0.3-3GHZ. When using The location key activation and encrypted information identification by ultra-high frequency signals will have a recognition range of more than 2 meters or even tens of meters, causing security problems, and the interface is not clear. At the same time, the information mobile terminal is inconvenient to carry. identification, causing the information identification time to be too long

Abstract

The invention discloses an intelligent information identification adopting method using an ultrahigh and ultralow frequency signal transmission way. The method is characterized in that a controller and an information card are provided and comprises the following steps that: S1, the controller emits a low-frequency signal regularly or after being triggered, and the information card enters a low-frequency signal zone and is activated by the low-frequency signal; S2, the information card activates a secret key in the low-frequency signal, new encryption information is generated after operation, and then information is sent to the controller by an ultrahigh-frequency signal; and S3, the controller receives the encryption information, carries out comparison to determine whether the result is wrong after operation, and generates a drive signal for carrying out switching control on a main switch, or carries out punching attendance information identification, or carries out system recording and displaying on effective information automatically. With the method, identification recording and transmission of information can be carried out effectively; the equipment can be carried conveniently; the display interface is clear; the identification time is short; the operation is convenient; and the identification safety range is ensured.
