Gas detection system of automatic teller machine

Abstract

The embodiment of the invention provides a gas detection system of an automatic teller machine. The gas detection system comprises a gas sampling module arranged in the automatic teller machine and a main control module electrically connected with the gas sampling module, the main control module is used for sending a sampling work instruction to the gas sampling module, and the gas sampling module is used for collecting gas in the automatic teller machine according to the sampling work instruction sent by the main control module; the gas detection module is connected with the gas sampling module; the data processing module is electrically connected with the gas detection module; the gas detection module is used for analyzing and detecting the gas collected by the gas sampling module and outputting a detection result electric signal, and the data processing module is used for outputting a gas abnormity warning signal according to a numerical comparison result of the detection result electric signal output by the gas detection module and a local threshold value. According to the invention, the abnormal gas in the automatic teller machine can be rapidly, accurately and conveniently detected, and the equipment safety and the public safety are guaranteed.

Description

technical field [0001] This application relates to the field of gas detection, in particular to a gas detection system for self-service teller machines. Background technique [0002] Self-service teller machine (Asynchronous Transfer Mode, ATM) is a high-tech product integrating computer technology, network technology, electromechanical technology, and automatic control technology. It is the key equipment for banks to realize self-service. As a common public facility, ATM machines are widely distributed and the users are complex, so their safety issues have always attracted much attention. For a long time, the focus of attention has always been on how to ensure the safety of ATM withdrawals, and safeguards such as preventing fraudulent brushes or being robbed during the withdrawal process have developed rapidly and have been gradually improved. As ATM machines are public funds deposit and withdrawal equipment, the issue of public security guarantee should not be limited to ...

AI Technical Summary

Problems solved by technology

[0003] Most of the common dangerous goods are volatile and semi-volatile organic compounds, which have good affinity and transfer characteristics to human skin and the surface of banknotes, so indirectly, banknotes will have corresponding organic residues, while self-service in the prior art The teller machine lacks related technologies for abnormal identification of banknotes that have indirectly come into contact with dangerous goods
