Embodiment
The invention will be further described below in conjunction with drawings and Examples.
Structured flowchart as shown in Figure 1, field monitoring equipment (1), transmission network (2), monitoring center's service end (3), monitoring center's client (4).
Field monitoring equipment (1) is by remote measurement intelligent rainfall meter (11), rubble flow infrasonic sound warning horn (12), and ultrasonic mud level meter (13) and image monitoring equipment (14) are formed.Be responsible for the collection and the processing of information such as on-the-spot rainfall amount, rubble flow infrasonic sound, mud position, image.Remote measurement intelligent rainfall meter (11) is put somewhere in the mudstone basin (this ground is the index place that the basin forms rubble flow), rain gage can be in real time with by the time (in minute) rainfall record, store and be sent to early warning system.The structured flowchart of remote measurement intelligent rainfall meter (11) specifically comprises as shown in Figure 2: rain sensor (111), signal gathering unit (112), data processing unit (113), data transmission unit (114).Rain sensor (111) is converted into pulse information with rainfall amount information, signal gathering unit (112) is counted the pulse that rain sensor (111) produces, data processing unit (113) filters and stores data, and data transmission unit (114) transmits packing data.
Rubble flow infrasonic sound warning horn (112) can receive seedbed, basin avalanche thing and enter the ditch bed, and rubble flow flows at the ditch bed, goes out the mountain pass, enters the infrasound signals of piling up fan and entering the main stem overall process.Thereby, can judge rubble flow generation and mobile, determine when warning on one's own initiative.The structured flowchart of rubble flow infrasonic sound warning horn (12) specifically comprises as shown in Figure 3: infrasound sensor (121), signal gathering unit (122), data processing unit (123), data transmission unit (124).Infrasound sensor (121) is gathered infrasound signals and is converted into electric signal, signal gathering unit (122) is to the electric signal of gathering infrasound sensor and be placed on filtering, data processing unit (123) filters and stores data, and data transmission unit (124) transmits packing data.
Ultrasonic mud level meter (13) monitoring mud position, when rubble flow circulation section was relatively stable, on ultrasonic sensor hanger canal bed, it was interim to measure rubble flow, implements to report to the police with the difference of mud position, and its lead depends on the distance at the equipment and the exit or entrance of a clitch.The structured flowchart of ultrasonic mud level meter specifically comprises as shown in Figure 4: ultrasonic probe (131), signal gathering unit (132), data processing unit (133), data transmission unit (134).Ultrasonic probe (131) transmits and receives ultrasound wave, according to hyperacoustic round-trip delay computed range, then range data is sent to signal gathering unit (133), signal gathering unit is gathered range data and is carried out filtering, data processing unit (133) filters and stores data, and data transmission unit (134) transmits packing data.
Image monitoring equipment (14) is placed in the basin and goes out near the debris flow gully bed of mountain pass, and it can be sent to system with the rubble flow image in real time.In addition, according to the image analysis principle, even under the condition of a video camera, if the distance of known incident angle and video camera and subject then can obtain parameters such as rubble flow flow velocity, width and tap height according to the image that photographs.The structured flowchart of image monitoring equipment (14) specifically comprises as shown in Figure 5: video camera (141), image acquisition units (142), picture coding unit (143), image transmitting unit (144).
Transmission network (2) is responsible for the data (rainfall, mud position, infrasonic sound, image etc.) of collection in worksite are uploaded to central station.Optionally transmission mode comprises GPRS/CDMA/3G or wired multiple communication modes such as (optical fiber, ADSL), according to on-site actual situations, selects flexibly.
Monitoring center is the native system information processing centre, comprises monitoring center's service end (3) and monitoring center's client (13).The disaster information that each field monitoring point device (1) is gathered is pooled to monitoring center's service end (3) by transmission network (2), monitoring center's service end (3) is handled and is stored information, related service department can utilize monitoring center's client (4) with relevant leader, monitors in real time and inquires about by multiple modes such as wireless network, Internet.
Monitoring center's service end (3) is made up of rainfall information receiving processing system (31), infrasonic sound message pick-up disposal system (32), mud position message pick-up disposal system (33), image receiving processing system (34).Rainfall information receiving processing system (31) receives and handles rainfall data, stores and adds up, and calculates rainfall intensity values such as rainfall accumulated value and ten minutes, a hour, 24 hours, and carries out early warning according to preset threshold and judge.Infrasonic sound message pick-up disposal system 32 receives infrasound signals, when signal has certain duration (reaching about 1 minute greater than 10 seconds) and certain intensity (the super 0.1pa of sound pressure level), can determine that just rubble flow takes place.Mud position message pick-up disposal system (33) receives and handles mud position information, from recording at the bottom of mud position and the primitive groove bed and obtain the rubble flow depth of water, if the ditch bed is more stable, then can calculate rubble flow flow velocity, flow according to depth of water section, its alarming threshold value is then decided by concrete basin.Image receiving processing system (34) receives and processing image information, writes down rubble flow in ditch bed flow motion overall process on the one hand, on the other hand according to video camera to ditch bed distance and incident angle, calculate the rubble flow surface velocity, tap height, the fluid width, and calculate parameters such as rubble flow flow.
Monitoring center's client 4 is made up of information display unit (41), data analysis unit (42), threshold value dispensing unit (43).Information display unit (41) is with the real-time information and the warning message of various diagrammatic forms demonstration rainfall, infrasonic sound, mud position, and the image information of monitoring point.Data analysis unit (42) is carried out statistical study to real-time and historical data, and rainfall, infrasonic sound, mud position and image information are carried out overall treatment judge, decision-making body can be according to this information issue yellow (from the threshold value of rainfall), orders such as orange (from infrasonic sound and mud position information) and red (from image) three kinds of alarms, issue are simultaneously withdrawn, taken refuge, close traffic line.Threshold value dispensing unit (43) can be managed for configuration alarm threshold value, improves alarm threshold value thereby constantly revise.
Adopt mud-rock flow early alarm system of the present invention, can be not reaching as yet under the technical conditions of accurate forecast at present, based on alarm, bound fraction faces a kind of mitigation means of the energy of reporting achievement.Before this, each individual event in the system all has the example of many practicalities, and native system organically makes up it, excavate every advantage, reach and complement each other, corroborate each other, bring into play modern communications technology simultaneously, make decision-making body can in time issue alarm, to reduce or to avoid casualties.
