Embodiment Construction

[0027] Such as figure 1 Shown, the present invention discloses a kind of smashed detection method that is applied to ATM machine, comprises the following steps:

[0028] In step S1, the sound signal and the vibration signal within the monitoring area of ​​the ATM machine are collected at the same time; the size of the monitoring area is determined by the range that can be collected by the sound collection equipment used and the range that can be detected by the vibration detector used.

[0029] In step S1, the collected sound signals and vibration signals are converted from analog signals into digital signals.

[0030] In step S2, judge whether described vibration signal is the vibration signal that ATM machine was smashed according to the intensity of described vibration signal, if vibration signal is strong vibration signal, then enter step S4, if vibration signal is weak signal, then Go to step S3;

[0031] In step S2, if the value of the vibration signal is greater than ...

Abstract

The present invention provides a smashed detection method and a smashed detection system applied to an ATM. The smashed detection method comprises the following steps: A, simultaneously acquiring a sound signal and a vibration signal within the range of a monitoring area of an ATM; B, judging whether the vibration signal is a vibration signal indicating that the ATM is smashed according to the intensity of the vibration signal, if the vibration signal is a strong vibration signal, entering a step D, and if the vibration signal is a weak vibration signal, entering a step C. The smashed detection method of the present invention has the beneficial effects that: a sound and vibration fusion method is adopted, a sound signal processing technology is introduced, and multiple judgments are performed on the basis of the vibration signal, thus the phenomena of false alarm and missing alarm caused by that only a vibration detector is used in the ATM at present can be effectively solved; in addition, identification judgment is added, so that an identification result is more reliable, and detection for other destroy sounds is also added, thus alarm judgment can be effectively made for the situation that the ATM is drilled and sawed.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a smashed detection method and system applied to an ATM. Background technique [0002] With the popularization and rapid increase of ATM (Automatic Teller Machine, automatic teller machine) machines, cases of violent crimes such as ATM machines being smashed and drilled are also increasing, bringing huge economic losses to banks. At present, banks often use vibration detectors to detect ATM machines being smashed, drilled and other criminal acts. However, the location where the shock detector is installed is different, and its alarm effect is different. Under normal circumstances, the vibration detector is installed inside the ATM machine and on the cash deposit safe, but it is often caused by human factors such as accidentally touching the detector when the ATM machine adds money, and false alarms are caused by impact drilling and drilling the wall due to insufficient s...
