The working method of technical solutions of the utility model, is divided into two large divisions: embedded mode and computing machine control and information processing manner:
(1) embedded mode
Embedded mode has two parts: the embedded mode of ARM7 and ARM9.The embedded mode of ARM7 mainly realizes collection, transmission, pre-service, transceiving data and instruction.The embedded mode of ARM9 mainly realizes forwarding data and instruction, and system alarm exports.
(2) computing machine controls and information processing manner
Computing machine controls to comprise following functions with information processing manner:
1. time-frequency conversion, wavelet transformation, wavelet package transforms and HHT extract eigenvector to vibration signal;
Traditional vibration signal characteristics parameter extracting method shortcoming is the assumed condition of feature based parameter short-term stationarity, Short Time Fourier Transform is utilized to investigate signal in a time frequency resolution determined, can not with the change tread adjustment time frequency resolution of signal, it is only described the static nature of signal, have ignored behavioral characteristics, this is a natural defect.When carrying out Short Time Fourier Analysis to every frame signal, the size of frame length determines the temporal resolution of system.When frame length is less, temporal resolution is high, but can be subject to the adverse effect of window function thus reduce frequency resolution, easily to jump signal tetchiness; When frame length is larger, although above-mentioned shortcoming can be overcome, but runs counter to the assumed condition of short-term stationarity, make analysis result occur distortion.The vibration signal that circumference fence sensor-based system collects is non-stationary signal, and its spectral characteristic changes in time.Therefore, when using the vibration signal of classic method to above-mentioned non-stationary to analyze, the accuracy of result can be restricted.In order to solve the defect of Short Time Fourier Analysis method when processing non-stationary signal, we introduce the methods such as time-frequency conversion, wavelet transformation, wavelet package transforms and HHT, window when can widen low frequency signal selectively.
2. Data fusion technique realizes multiple spot vibration detection simultaneously, simultaneously multipoint positioning;
Multiple spot vibration detection and simultaneously multipoint positioning are one of difficulties of vibration perception perimeter security crime prevention system.Traditional vibration detection and location how based on single-sensor, and provide One-Point Location result.But in actual applications, the generation of multiple spot invasion situation cannot be avoided, now just need the method that can realize multiple spot vibration detection and multipoint positioning.We introduce in nearly 10 years and are developed rapidly and entered the Data fusion technique of many applications, and by special hardware design, realize the detection and positioning to invading some vibration signals more.
3. tree-shaped categorised decision technology, human assistance learning process isotype recognition technology Optimizing Mode coupling, realizes invader and cuts, climbs, crosses, pushes over the identification that circumference fence invades behavior.
Intrusion behavior identification is another difficulties of vibration perception perimeter security crime prevention system.Traditional recognition method often can run into the not high problem of pattern match degree in practice process.Cause the reason of this problem to have two aspects, be that the sensing hardware designing natural of security system is not enough on the one hand, cause the limitation that pattern match degree improves; Be the deficiency of algorithm for pattern recognition on the other hand, be difficult in theory improve pattern match degree.We introduce tree-shaped categorised decision technology, human assistance learning process isotype recognition technology, fully utilize the vibration information that multiple sensor and sensor unit group collect, carry out Optimizing Mode coupling from hardware configuration and theoretical algorithm two aspect, thus improve matching degree.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
