ATM anti-theft card system / ATM anti-mask alarm principle
Using the advanced laser guidance ranging and positioning system in the military field, the accuracy reaches millimeter level, and accurately judge whether there is an abnormal state in the ATM teller card slot! Ensure that the false alarm rate reaches 1 in 10,000. Once an abnormal change is found in the card slot, it immediately sends a signal to the central control system and the 110 linkage device through the network and the signal port. At the same time, it links the on-site video surveillance host to record the criminal's video recording. , At the same time can link the on-site sound and light device. Has applied for the national patent right.
Implementation principle:
First, multi-point ranging is performed on the card reader of ATM machine and other self-service equipment and its surroundings through a high-precision laser ranging system, and the measurement result is saved as a reference value. During normal operation, the card reader of the self-service equipment such as ATM machine is measured according to a certain period or preset conditions, and compared with the stored measured value according to the received measured distance value, when the measured distance value does not exceed the alarm distance When the parameter value is maintained, the current state is maintained; when the measured distance value exceeds the alarm distance parameter value, indicating that the physical state or form around the reader has changed, an alarm signal is sent to the control module, and the continuous alarm time is counted. If the continuous alarm time statistics exceed the threshold value of the pre-warning time parameter, the control module sends out pre-warning instructions and pre-warning warning signals through the Internet of Things module, and at the same time avoids false alarms caused by normal actions such as card insertion;
This system uses a phase-type laser ranging module to achieve high-precision laser multi-point ranging. A laser protective net can be formed around the card reader. Because the device is hoisted at a certain distance in front of the self-service device, it is not only convenient to set up, good concealment, and no need to damage Self-service equipment, flexible installation location, can be installed within a distance of 0.05 meters to 20 meters from the ATM machine card reader; in addition, the laser light path of the device not only has a large detection range, but also is not easily affected by the environment and electromagnetic interference, effectively solving the traditional The problem of equipment false alarms and omissions.
The Internet of Things module is specially set in the system, which can monitor the card slot status of the ATMs of each network point in real time through the central network, and can report to the center in time for any abnormal conditions of the card slot. At the same time, it can be connected with Yuantuo's SMS alarm module to send SMS alarm to relevant personnel or the SMS platform of the public security department.
