As the important technology feature, method for safety monitoring of the present invention and system had both possessed traditional function of utilizing wired or RF networking and reaching monitoring and detect, and hearing ability that again can the anthropomorphic dummy is come the monitoring of environmental sound variation.After debugging, can be automatically and discern normal ambient sound reliably, distinguish the alerting signal that various unit monitoring system is sent reliably.This method is utilized the path of the air medium of nature as the alerting signal transmission, networks with various warning devices by real-time continuous ground monitoring voice signal.Because do not need the networking of wiring or RF signal, thereby can bring into play its dirigibility to greatest extent, low price, easy for installation.Can network with any existing Shi Chang Bao alarm device, have compatible widely.Can be with three-dimensional or four-dimensional, the signal coupling of promptly expanding the information dimension of commercially available acoustic alarm signal improves system reliability and reduces false alarm.
The system integration principle of for example fire prevention of general alarm of the present invention, Smoke prevention, anti-coal gas as shown in Figure 1.Now its basic functional principle is summarized as follows,
If wherein sensor 1,2 or sensor N are when alert takes place, the alerting signal of sounding respectively S1, S2 or SN, by shown in Figure 2 multistage, the above acoustic coupling principle of one-level or secondary for example, system's microphony sensor is to the sound mix signal of this alerting signal and neighbourhood noise and background, the alerting signal that report to the police in the promptly interior at home unit that distributes or monitoring sensor sent and mixed signal and the detected signal synthesis waveform of supervisory system and the spectrogram of interference sound and environmental noise are as Fig. 3.Signal processing unit at first switching signal becomes spectrogram, carries out further signal analysis again, feature extraction and signal identification.Its principle and procedural representation such as Fig. 4.
In above-mentioned signal analysis, on feature extraction and the signal identification basis,, then can expand the reliability of its signal identification if the variation of signal is further encoded; The multi-dimensional signal coupling as shown in Figure 5.
One typical applied in any combination frequency coding, time encoding and intensity coding scheme have shown the reliability that how to improve signal transmission and identification, thereby have improved the reliability of the alerting signal identification of supervisory system.
Typical as shown in Figure 5 special-purpose alerting signal has comprised:
The time dependent rule of signal frequency: f1 f2 f3
Signal duration is rule over time: T1 T2 T3
With the signal intensity change with time: P1 P2 P3
About the warning accuracy rate, be p as if environmental noise or other machine and the equitant false alarm rate of non-alerting signal in a certain characteristic frequency (or frequency conciliation) alerting signal and the daily life, then its warning accuracy rate is (1-p).Add frequency coding (N kind frequency, as N=3 then N!=6) after, the warning accuracy rate is (1-p
).Add time encoding (M section time such as M=3 then M!=6) after, the warning accuracy rate is (1-p
* M!).Add intensity coding (L section intensity such as L=3 then L!=6) after, the warning accuracy rate is (1-p
* M! * L!).Along with the increase of codec complexity, the warning accuracy rate is also along with improve.
Visit the probability that calibration signal is not promptly failed to report: as long as alerting signal is kept the sufficiently long time (time requirement of T 〉=system's reliable detection) and enough intensity, intelligence system has high verification and measurement ratio.
Signal excessively a little less than, as too far away apart from intelligent monitor system, may cause system's detection difficult because of alarm.The pass of attenuation of signal intensity and distance is:
The quantitative relationship of decay is: I (r)=I (r=1)-20log (r
2) 1≤r≤∞
I (r) is the intensity of signal in the r distance.I (r) with the signal of distance r relation as shown in Figure 6.
Typical at home all in the square scope of 20m, corresponding to the maximum monitoring distance of r=10m.This is typical monitoring range at home.In this scope, peak signal decays to 40dB.
Even under very big at home situation, major part must be in the square scope of 40m.When r=20m, maximum signal attenuation still is 52dB.Because the strength retrogression of sound, away from alarm, signal reaches intelligence system and may decay to too faint level (decay is greater than 50dB) and make intelligence system can't detect its signal as if the center detection system.An easy as shown in Figure 7 signal adapter can address this problem for this reason.
Alerting signal among Fig. 7 is when intensity is amplified, and shown in Fig. 7 a, its frequency should be converted into a new signal frequency, thereby can avoid the self-sustained oscillation of alerting signal.For this reason, the frequency setting of signal must limit to some extent, amplifies and drift in order to avoid signal feedback causes the self-excitation of signal.With the principle of bandpass filter restricting signal feedback shown in Fig. 7 b.
If frequency coding is arranged, then need use logical frequency of a plurality of bands or thin shape bandpass filter, in order to avoid signal feedback and cause self-sustained oscillation.
Intelligence system of the present invention can be designed to have recognition function and self-learning function.
This intelligence system can be remembered different alerting signal sources by pre-study.When a certain specific alerting signal of test, press the learning functionality key of intelligence system, intelligence system will extract and remember the key feature in time this alerting signal source.
This intelligence system can be discerned different alerting signal sources by detection, thereby improves the efficient and the accuracy of reporting to the police.
This intelligence system can have self-teaching and improve the function of resolution, can accurate recognition go out real alerting signal, and distinguish out the environmental background signal.
This system is comprehensively multi channel signals detection also, thereby improves the level of intelligence and the identification certainty of system.
