Abstract

An induction-based data identification system having real-time response, including a plurality of mobile identity terminals that can be carried, a gateway system, and a background computer. The system configuration and method process are reasonable. It has the features of recording any update status data of the objects and real-time response without being affected by large amount of information. In addition, the mobile identity terminal has a low power consumption, suitable for the occasions of long-time use, such as anti-theft systems of shopping malls, places of detention, and warehouse management.

Claims

1. An induction-based data identification system characterized by real-time response, comprising:

a plurality of mobile identity terminals that can be carried, and the mobile identity terminal is equipped with a controller portion, an alarm portion, an interactive communication storage portion, wherein the interactive communication storage portion comprises a RF receiving portion, a RF transmitting portion, a HF signal induction portion, and a data storage portion, the RF receiving portion is connected to the controller portion via a serial mode and the HF signal induction portion is directly connected with the controller portion via wires;

the data identification system further comprises;

a background computer, which is entered with the data carrying objects of the mobile identity terminal in advance;

a gateway system, which is arranged in a fixed way and provide with an antenna for direct data communication with the RF receiving portion of the interactive communication storage portion of the mobile identity terminal, a communication module that communicates with the background computer, an alarm module and a control module, the antenna transmits HF signals with the command information and data information for receiving by the RF receiving portion of the interactive communication storage portion of the mobile identity terminal in the signal coverage area;

the gateway system transmits HF inquiry signals for inquiry via the antenna, the interactive communication storage portion of the mobile identity terminal can trigger the pre-set response process after its HF signal induction portion receives the HF inquiry signal, and the object data stored in the data storage portion are transmitted in real time manner by the RF transmitting portion, the antenna of the gateway system reads the object data and enter the data into the background computer, then the data are compared with the pre-entered object data in the background computer to judge if the object is in a normal state according to the matching condition;

if the object is determined in an abnormal state, the background computer records the current status data of the object to the background database, and sends abnormal status flag data to the gateway system, and the control module of the gateway system makes its alarm module to give alarms and transmit abnormal status flag data via the antenna, after the RF receiving portion of the interactive communication storage portion of the mobile identity terminal receives the abnormal status flag data, the abnormal status flag data will be directly stored in the data storage portion of the interactive communication storage portion of the mobile identity terminal according to the pre-set response process;

the controller portion of the mobile identity terminal is in a sleep state under the normal state, when the mobile identity terminal enters the antenna signal coverage area of the gateway system, the HF signal induction portion of the interactive communication storage portion of the mobile identity terminal receives high-frequency inquiry signals transmitted from the antenna, the induction signals of the high-frequency inquiry signals are triggered by the HF signal induction portion of the controller portion of the mobile identity terminal, and awaken from the sleep state, to read the data storage portion of the interactive communication storage portion, when the abnormal status flag data are read, the alarm portion of the mobile identity terminal gives alarm and the alarm time information is recorded in the data storage portion of the interactive communication storage portion.

2. The induction-based data identification system characterized by real-time response according to claim 1, wherein the controller portion of the mobile identity terminal can read the data storage portion of the interactive communication storage portion when awaken, and if no abnormal status flag data are read, it is considered to have a normal data checking operation at this time, and the normal data checking operation information is recorded in the data storage portion of the interactive communication storage portion.

3. The induction-based data identification system characterized by real-time response according to claim 1, wherein the mobile identity terminal is also provided with a switching signal generating portion, and the switching signal generating portion is connected with the controller portion;

the switching signal generating portion is equipped with cables, and switching signals are generated by cable breakages, and the cables are used to connect the mobile identity terminal to the object;

when cables break, the switching signal generating portion generates switching signals to awake the controller portion of the mobile identity terminal, the controller controls the alarm portion to give alarm and record the time of cable breakage in the data storage portion of the interactive communication storage portion.
