Abstract
The embodiment of the invention discloses an automatic alarm method based on bank security. The method includes the following steps: under a usual normal work state, acoustic parameters of voices of a teller during communication with a customer are acquired automatically from a backstage and amplitude, frequency, voice intensity and pronunciation speed of the voices are analyzed and quantized and stored in a memory and used as voice characteristics under a normal state; real-time acoustic characteristics of a current teller are acquired regularly at a specific period and then compared with the acoustic characteristics under the normal state and when two or more characteristics in the comparison result exceed a set alarm threshold, the backstage alarms automatically. Through adoption of the automatic alarm method based on the bank safety, according the change of the acoustic characteristics of the teller, whether threats exist is judged and automatic alarm is sent.
Description
Technical field
The present invention relates to a kind of automatic alarm method, relate in particular to a kind of automatic alarm method based on bank safety.
Background technology
Current, when bank's grain is plundered, Receptionist is on the hazard and controls, and can not report to the police timely, to retrieve a loss, and lawless person is controlled in time, thus, need to aly can, according to sales counter staff's state, judge the threat automatic alarm existing.
Summary of the invention
Embodiment of the present invention technical matters to be solved is, a kind of automatic alarm method based on bank safety is provided.Can judge whether to exist to threaten according to the change of teller's acoustic feature, and automatic alarm.In order to solve the problems of the technologies described above, the embodiment of the present invention provides a kind of automatic alarm method based on bank safety, comprise the following steps: under normal operation in normal state, parameters,acoustic from the sound of backstage automatic acquisition teller and customer communication, analyze wave amplitude, frequency, loudness of a sound, the rate of articulation of described sound, and quantize to be accessed in storer, as the sound characteristic under normal condition; With some cycles, periodically obtain current teller's real-time acoustic feature, and compare with the sound characteristic under described normal condition, when the result of described comparison has more than two or two features to exceed the alarming threshold value of setting, report to the police automatically in backstage.Further, sound characteristic under described normal condition is regularly obtained real-time acoustic feature and the acoustic feature of having stored to be compared in the cycle of setting, if in threshold values, preserve described real-time acoustic feature temporarily, and obtain next real-time acoustic feature, then row is relatively, obtaining under number of times of setting, continuously normal real-time acoustic feature is carried out comprehensively, and calculate comprehensive acoustic feature as the sound characteristic under normal condition.Implement the embodiment of the present invention, there is following beneficial effect: can judge whether to exist to threaten according to the change of teller's acoustic feature, and automatic alarm.
Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below the present invention is described in further detail.A kind of automatic alarm method based on bank safety in embodiments of the present invention, comprise the following steps: under normal operation in normal state, parameters,acoustic from the sound of backstage automatic acquisition teller and customer communication, analyze wave amplitude, frequency, loudness of a sound, the rate of articulation of described sound, and quantize to be accessed in storer, as the sound characteristic under normal condition; With some cycles, periodically obtain current teller's real-time acoustic feature, and compare with the sound characteristic under described normal condition, when the result of described comparison has more than two or two features to exceed the alarming threshold value of setting, report to the police automatically in backstage.Sound characteristic under described normal condition is regularly obtained real-time acoustic feature and the acoustic feature of having stored to be compared in the cycle of setting, if in threshold values, preserve described real-time acoustic feature temporarily, and obtain next real-time acoustic feature, row relatively again, obtaining under number of times of setting, continuously normal real-time acoustic feature is carried out comprehensively, and calculate comprehensive acoustic feature as the sound characteristic under normal condition.Above disclosed is only a kind of preferred embodiment of the present invention, certainly can not limit with this interest field of the present invention, and the equivalent variations of therefore doing according to the claims in the present invention, still belongs to the scope that the present invention is contained.
Claims (2)
1. the automatic alarm method based on bank safety, it is characterized in that, comprise the following steps: under normal operation in normal state, parameters,acoustic from the sound of backstage automatic acquisition teller and customer communication, analyze wave amplitude, frequency, loudness of a sound, the rate of articulation of described sound, and quantize to be accessed in storer, as the sound characteristic under normal condition; With some cycles, periodically obtain current teller's real-time acoustic feature, and compare with the sound characteristic under described normal condition, when the result of described comparison has more than two or two features to exceed the alarming threshold value of setting, report to the police automatically in backstage.
2. method according to claim 1, it is characterized in that, sound characteristic under described normal condition is regularly obtained real-time acoustic feature and the acoustic feature of having stored to be compared in the cycle of setting, if in threshold values, preserve described real-time acoustic feature temporarily, and obtain next real-time acoustic feature, row relatively again, obtaining under number of times of setting, continuously normal real-time acoustic feature is carried out comprehensively, and calculate comprehensive acoustic feature as the sound characteristic under normal condition.
