Abstract
The utility model provides a landslide monitoring alarm device based on laser ranging, and belongs to the technical field of the disaster prevention and reduction. The landslide monitoring alarm device based on laser ranging comprises a laser rangefinder, a three-dimensional rotary bracket, a monitoring alarm host, an alarm whistle, and a data recorder. The landslide monitoring alarm device based on laser ranging has advantages of non-contact monitoring mode, high measurement precision, strong anti-interference capability, little influence by environment, no influence from various terrains (especially some construction workers hard to reach areas), small size, light weight, flexible and convenient installation for the device, nobody waiting on a monitoring site, etc. By using a fixed sampling time interval or selective examination mode at any time, a plurality of monitoring points are automatically high accurate, high reliable, real-time, continuous, remote wireless monitoring and alarm. The landslide monitoring alarm device based on laser ranging can be widely applied to automatic monitoring and alarm such as landslides, collapse and falling stone.
Description
Technical field:
The present invention relates to use laser range finder to carry out automatic continuous monitoring to In Situ Displacement of Slope, be specifically related to a kind of landslide monitoring warning device based on laser ranging.Belong to the technical field of preventing and reducing natural disasters.
Background technology:
Landslide is slope Rock And Soil along the slippage geological phenomenon of being used to logical shear breakage and occurring, and industrial and agricultural production is usually given on landslide and people's lives and properties are that 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. establish station observation method; 3. instrument observation method; 4. pattern-recognition method; 5. GSM monitoring method; 6. radar scan.Every kind of 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 need to be installed sensor or the equipment of displacement monitoring on the main crack of sliding mass or limit, crack, if main crack is to be difficult for workmen the region arriving, has just increased installation difficulty and danger.
Summary of the invention:
The technical problem to be solved in the present invention be to provide high, affected by environment little, the non-contact type monitoring of a kind of measuring accuracy, easy to use, can real-time automatic measuring print and report to the police and use wireless network by the device of information remote transmission by the settings early warning value that comes down.
A landslide monitoring warning device based on laser ranging, forms measuring system by runing rest (1), laser range finder (2); Memory (3), control module (4), interface module (5), wireless module (6), digital display screen (7) composition monitoring alarm host machine, together with datalogger (9), siren (8) 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.
Runing rest (1) is three-dimensional rotation support, comprises hand head and base support, can drive laser range finder to do three-dimensional rotation to multiple positions of setting and find range; Control module (4) is responsible for providing total system timed power on/off signal, positional information is provided to runing rest (1), the various information that processing is transmitted by wireless network and laser range sensor, send data and differentiate displacement the alarming threshold value that whether reaches setting to memory (3), datalogger (9); Wireless module (6) is responsible for receiving and transmission information; Siren (8) is for onsite alarming.
The present invention has the following advantages:
1, monitoring accuracy is high, and general measure scope is less than 2mm in the measuring error of 0.05-250 rice;
2, antijamming capability is strong, affected by environment little, volume is little, lightweight, device convenient and flexible installation, adopt contactless installation, be not subject to the various influences of topography, especially the very unattainable area of some workmens;
3, speed simple to operate is fast, monitors more flexibly, can carry out dynamic monitoring to object (falling rocks, landslide).
4, can to monitoring device, carry out long distance wireless operation and inquiry at any time.Without operating personnel, wait at the scene, while reaching the early warning value of setting, device automatically with wireless mode report and alarm information to Surveillance center, and send sound and light alarm.
5, this monitoring mode belongs to contactless monitoring, is not subject to the various influences of topography, the especially very unattainable area of some workmens, monitoring field need not near or enter monitored area, equipment is not fragile, reusable yet, reduce maintenance cost.
Accompanying drawing explanation:
Fig. 1: the structural representation of the utility model device.
Wherein: 1-runing rest; 2-laser range finder; 3-memory; 4-control module; 5-interface module; 6-wireless module; 7-digital display screen; 8-siren; 9-datalogger;
Fig. 2: the scheme of installation of the utility model device.
Wherein: 12-solar panels; 13-monitoring alarm host machine; 14-controller for solar; 15-accumulator; 16-antenna; 17-rain-proof anti-theft case; 18-support; 20-landslide fissure; 21-sliding mass; A1, A2, A3, A4, A5, A6-are landslide monitoring point.
Embodiment:
As shown in Figure 2, consider field use inconvenience, this Landslide Forecast System is selected solar powered.At the local fixed support (18) and the rain-proof anti-theft case (17) that not affected by landslide, solar panels (12) are installed at top, in case, lay controller for solar (14), accumulator (15), monitoring alarm host machine (13), runing rest (1), datalogger, laser range finder is fixed on runing rest, connect all power, data line, choose monitoring point A1, A2, A3, A4, A5, A6.Debugged laser ranging direction, opening power, measures the initial distance data of current each monitoring point to the machine; Set displacement alarming threshold value, sampling time interval, many group reception phones, alarming short message content, tone information.
During each sampling, monitoring alarm host machine is opened all power by the sampling time interval setting automatically, be followed successively by three-dimensional rotation support positional information is provided, laser range finder can be passed to monitoring alarm host machine by the data in each position measurement successively, and data are recorded the data (period, date, time, distance) of each monitoring point after treatment automatically by datalogger.Initial value, currency, the shift value (shift value=current distance value-initial distance value) of the each monitoring point of aobvious screen display of monitoring and alarming system work hours;
During sampling, by wireless network, to monitoring and alarming system, send the request of measurement, monitoring and alarming system is worked by fixed sample monitoring mode immediately, and returns whole measuring point datas on mobile phone or computer.
When shift value is more than or equal to the displacement alarming threshold value of setting, on-the-spot siren rings, monitoring and alarming system sends alarming short message, and the phone setting is dialed in circulation immediately.Remind the displacement of responsible person concerned's observation station to reach the displacement alarming threshold value setting, must take the emergency preplan that comes down at once.
