Background technology:
Landslide is the slippage geological phenomenon that slope Rock And Soil occurs along used logical shear breakage, and industrial and agricultural production is usually given on landslide and people's lives and properties bring about great losses, have or even destructive disaster.China is the country on mountain more than, and mountain area accounts for 69.4% of China's land total area, and mountain area population accounts for the over half of country's total population.Mountain area geology complex structure, ecological environment frailty; Along with Construction of The Mountainous Region speed is accelerated, ecologic environment is destroyed, and the mountain region disasters such as rubble flow, landslide, avalanche, mountain torrents break out frequently.According to statistics, mountain region disaster causes China's economic loss to reach 5,700,000,000 yuans every year on average, and wherein landslide accounts for more than 60%.The struggle on the mankind and landslide is long-standing, and the method for use is greatly to being divided into: 1. simple observation method; 2. station observation method is established; 3. instrument observation method; 4. pattern-recognition method; 5. GSM monitoring method; 6. radar scan.Often kind of a method has relative merits, or monitoring accuracy is low, can not 24 hours round-the-clock monitoring, alarmings; Have high input, be not easy to apply.First three methods all needs on sliding mass major cracks or limit, crack, install displacement monitoring sensor or equipment, if major cracks is the region not easily arrived workmen, just increases installation difficulty and danger.
Summary of the invention:
The technical problem to be solved in the present invention be to provide the monitoring of a kind of measuring accuracy high, affected by environment little, non-contact type, easy to use, can print and be undertaken reporting to the police and the method using wireless network to be transmitted by information remote and device by setting the early warning value that comes down by real-time automatic measuring.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: invent a kind of landslide monitoring alarm method based on laser ranging and device, its gordian technique is: by multiple runing rest, laser range finder, form measuring system, control module, memory, wireless module, interface module, digital display screen composition monitoring alarm host machine, together with siren composition monitor and alarm system, be stored in the various data in monitor and alarm system, can not disappear because of power-off, see Fig. 1.Solar panels, controller for solar, accumulator composition electric power system.
In FIG, laser range finder is for measuring the distance of base station to monitoring point reflecting plate, and runing rest is three-dimensional rotation support, comprises hand head and base support, laser range finder can be driven to make three-dimensional rotation and find range to the position set; Control module is responsible for providing timed power on/off signal, process the various information transmitted by wireless network and laser range sensor, send data to digital display screen, memory and differentiate whether shift value (or change in displacement speed) reaches the alarming threshold value of setting; Wireless module is responsible for receiving and transmission information; Siren is used for onsite alarming, and its principle of work flow process is shown in Fig. 2.Solar panels convert solar energy into electrical energy and be sent in accumulator by controller for solar to store, by accumulator for measuring system and monitor and alarm system provide the electric power of needs.
The present invention has the following advantages:
1, monitoring accuracy is high, and general measure scope is less than 3mm in the measuring error of 0.05-200 rice;
2, antijamming capability is strong, affected by environment little, volume is little, lightweight, device convenient and flexible installation, not by the various influence of topography, the especially very unattainable area of some workmens;
3, speed simple to operate is fast, and monitoring is more flexible, can carry out dynamic monitoring to object (falling rocks, landslide).
4, long distance wireless operation and inquiry can be carried out to monitoring device at any time.Wait at the scene without the need to operating personnel, when reaching the early warning value of setting, device automatically wirelessly report and alarm information to Surveillance center, and send sound and light alarm.
5, this monitoring mode belongs to contactless monitoring, monitoring field need not near or enter monitored area, equipment is not fragile, reusable yet, reduce maintenance cost.
