In the time of sensor installation group, as shown in Figure 4 and Figure 5, described multiple sensor groups are evenly distributed on around protected area, and each sensor group is apart from border, protected area 20KM; Described one point sensing device is by being more than or equal to the spacing word order of 50 meters on basement rock.
Below each part mentioned above principle of work is specifically described:
The present embodiment adopts main three homophase bender hydrophone composition one point sensing device groups that detect primary seismic wave, to improve seismic wave first motion accuracy of detection and to eliminate the interference that non-seismic event causes.
One point sensing device is by highly sensitive piezoelectric ceramic piece and the vertical single compressional wave wave detector forming to spring weight, and it can detect the primary seismic wave of higher-frequency (near earthquake) delicately, can improve the inhibition ability that periphery is disturbed by the setting of measurement bandwidth simultaneously;
Sensor group: above-mentioned three wave detectors are laid on basement rock by the interval word order of 50 meters, to form the detecting sensor group SQ1-SQ8 of single-point.As shown in Figure 6, if interfering seismic sources is positioned at sensor S1 in one line, S2, on the middle separated time of S3 with the position at sensor S2 distance 300 places, now, interfering seismic sources distance and sensor S1, S2 distance approximately 304, can be calculated vibrations compressional wave and arrive sensor S1, the arrival time difference of S3 and arrival sensor S2 is 0.67ms, the measuring and calculating of the time length by arrival time difference can effectively identify closely the vibrations of (in 300 meters) and disturb, three wave detectors detect that interference source vibration signal first motion has the obvious time difference (>0.5ms) to be identified as interference, hardware circuit is easy to this identify.Because earthquake generally all occurs in the place of underground several kilometers to tens kilometers, therefore, the time difference that its seismic wave arrives each wave detector will, much smaller than 0.5ms, can wrong differentiation be not interference.
When sensor group is laid; as Fig. 7-Fig. 8 and in conjunction with as shown in Fig. 5, in the present embodiment, eight groups of sensor groups are laid in respectively to protected area around; each sensor group is apart from the about 20Km in border, protected area; for the ease of calculating, be uniformly distributed as far as possible, establishing protection zone radius is 5Km; source depth is 10Km; it is 25Km that sensor is laid radius, and velocity of longitudinal wave is 6Km/s, and shear wave velocity is 3.5Km.
: compressional wave arrives the required time T p=L/6=of nearest sensor group
/ 6;
Shear wave arrives the required time T s=D/3.5=in border, protected district
/ 3.5;
Earthquake pre-warning duration △ T=Ts-Tp(arrives the mistiming on border, protected district from the secondary wave of reporting to the police).
As can be seen from the figure in the middle of source location is in two sensor groups on bisectors time, it is the longest that compressional wave passes to the distance L that sensor group walks, and that shear wave passes to the distance on border, protected district is constant, i.e. △ T minimum.Therefore the duration △ T that, this system at least can early warning to the destructive near earthquake of different distance is:
20Km：△T=4s
30Km：△T=6s
40Km：△T=7.5s
50Km：△T=8.8s
60Km：△T=10s
70Km：△T=11.3s
80Km：△T=12.5s
90Km：△T=13.7s
100Km：△T=14.9s
Seismic waveshape identification and warning module disturb fast with intensity and identify the received vibration signal of sensor group; in the time meeting trigger alarm condition, the terminal to protected district is sent alerting signal immediately, and the whole identification trigger alarm signal process time is less than 0.1 second.Its each several part ultimate principle:
Vibrations are disturbed and nearly macroseism identification: first the waveform voltage signal from three one point sensing devices is differentiated through amplitude, if all exceed set threshold value, also to carry out phase bit comparison, in the time that first motion arrival time difference is greater than 0.5ms, be judged as due to the interference of nearly source, AND circuit is output as " 0 ", and CPU does not carry out recording processing to signal waveform, does not also send triggering command simultaneously.If contrary signal from 500 meters with ruinous earthquake compressional wave far away, Qi San road signal first motion arrival time difference should be less than 0.5ms, is now output as " 1 " with door, and CPU processor sends alarm command at once, carry out the identification estimation of waveform recording and earthquake intensity grade simultaneously, and send it to information terminal.
Earthquake intensity grade identification estimation: in the time being defined as nearly macroseism and sending warning triggering command through above-mentioned identification; A/D gets off front several waveform recordings of this primary seismic wave; and immediately its amplitude-frequency characteristic is compared; estimate this earthquake to the issuable earthquake intensity grade in protected district, its result is counted leaflet unit by network and is sent in real time information terminal (this process is generally less than 0.25s).
Warning trigger pip real-time Transmission: this function is mainly counted leaflet unit, vpn routers and Wireless Date Transmission Channel by network and completed.In the time receiving the warning triggering command that CPU processor sends, network is counted leaflet unit and is sent alarm command by vpn routers and Wireless Date Transmission Channel to the information terminal of real-time connection LAN (Local Area Network), after earthquake intensity grade estimates (than late about 0.2 second of alarm command), then send earthquake intensity grade to information terminal.
Report to the police and trigger: when early warning information terminal PC prow first detects after certain number alarm unit trigger alarm instruction that network transmits, trigger corresponding sound, light crossing-signal (information how long arriving in addition with secondary wave) by RS232 serial ports immediately.
Seismic source information measuring and calculating and demonstration: in trigger alarm, terminal PC then then compares with first instruction of second request trigger alarm unit triggers, can obtain the orientation (as shown in Figure 3) of focus.Main orientation is in the geophone group direction of first triggering, and deflection second triggers angle and two groups of time difference correlations (maximum is no more than 22.5 °) that geophone group triggers of geophone group.Epicentral distance can poor by the secondary triggered time of the first triggering geophone group (being that shear wave triggers moment-compressional wave triggering moment) be determined.Destruction (earthquake intensity) grade to one's respective area, the compressional wave amplitude-frequency characteristic that can trigger geophone group by first is estimated.After calculating out, above-mentioned seismic source information can be presented on relevant display screen.
The automatic startup of protective device: some lifeline engineering project, as oil, feed channel, nuclear power facility etc. and the high-speed cruising vehicles, as high ferro, express elevator etc. must be closed and stop before ruinous earthquake arrives, in order to avoid cause serious secondary disaster.This system can be sent the instruction of closing and braking to different LAN subscriber in advance, is also above-mentioned alarm command, automatically starts different protective device (non-this patent product facility), to realize the fast and safely response of above-mentioned each system.

Step1, multiple spot detect primary seismic wave;
Step 2, detection primary seismic wave signal carry out intensity and Phase Processing, identification undesired signal;
