Description
Technical field
The present invention relates to a kind of reservoir dam monitoring devices, specifically a kind of to monitor system applied to reservoir dam
Centralized Controller.
Background technology
Concrete dam and stone masonry dam are built up after water storage uses, water, silt, wave, uplift pressure, temperature and the earthquake the effects that
Under, it necessarily deforms, seriously causes to collapse, case is too numerous to enumerate.Dam safety monitoring technology is international concern problem.
Dam structure safety monitoring system is related to multiple ambits such as optics, sensor, electronics, two ranks of development experience
Section：
1, observation stage (1891~1964 years), also referred to as prototype measurement.Because the level monitoring in the stage is relatively low, only pair
The monitoring instrument being placed on dam structure manually observe and detect, and records dam real-time status.
2, the stage of security viewpoint direction finding safety monitoring transformation and development (nineteen sixty-five is so far).It gradually anticipates in domestic external monitor field
Know the limitation of instrument detection, just dam is combined using artificial inspection with Instrument observation.Wherein Japan, the U.S. are earliest
The country of walkaround inspection is carried out, then also all regulation must carry out dam for the country such as France, Canada of Italy and Norway
Manual inspection, to effectively avoid the defect for only carrying out safety monitoring to dam with observation instrument.But due to manually patrolling
The variation on dam surface can only be observed, and the variation of the labyrinth of its inside and security risk are difficult to distinguish, it is therefore necessary to
Invent a kind of monitoring technology that can at any time, everywhere, in time, efficiently reflect and detect dam safety issuess.The later stage sixties,
External many countries are studied and are manufactured to the instrument and equipment for monitoring dam safety automatically：Japan realizes on arch dam first
Automatic collection is carried out to monitoring data；Later, Italy successively realizes plumb instrument deformation auto-monitoring and centralization acquisition number
According to system；1989, Canada will carry out the automation inspection of the functions such as data acquisition, storage, processing, long-range and analysis
Examining system is mounted on dam.China carries out dam deformation since the eighties and monitors, and also has developed distributed intelligence detection
Data collecting system, wireless communication module and the software systems for safeguarding dam network safety information.
Two ways is used to dam deformation monitoring in the world at present：
1, according to basic point elevation and position, theodolite, spirit level, electronic distance meter or laser collimator, GPS, intelligence are used
Can total powerstation etc. come measure dam body surface monument, elevation and change in location at surveyor's beacon.The three-D displacement data that measuring point can be achieved are surveyed
Amount；
2, the instrument for installing or burying some monitoring displacements on dam body surface is typically only capable to measure the individual event displacement number of measuring point
According to (horizontal displacement or vertical displacement).Common displacement monitoring instrument has displacement meter, crack gauge, dipmeter, sedimentometer, vertical line to sit
Mark instrument, tensile-line instrument, multipoint displacement meter and strain gauge etc..
For deformation monitoring equipment, from the perspective of from several respects such as precision, stability, installing engineering amount, maintenance, prices, it can be full
The equipment of sufficient requirements almost without.Dam body internal displacement monitoring can only use traditional individual event displacement monitoring equipment, need
Pre-plugged or drilling installation are wanted, construction is inconvenient, and there is presently no good alternatives；Three dimensions that dam body surface displacement uses
It is easy for installation according to monitoring device, performance is stable, precision is high, but is influenced by geographical environment, mounting condition is restricted, and cost
It is high.
Research and development one kind is not influenced by geographical environment as a result, and the response time is fast, and high certainty of measurement is convenient for, it can be achieved that self calibration
Realize that the dam deformation automatic monitoring system of intelligent digitalized management is significant.
Patent of invention《Reservoir dam depression and horizontal displacement Trigger jitter detection device and detection method》[the patent No.
ZL201410450657.8] and《Reservoir dam depression and horizontal displacement monitoring system》[patent No. ZL201410450695.3] is detailed
The thin principle and method for elaborating to monitor dam deformation based on Principles of Laser.Key technology is to pass through observation point using laser beam
" cross " refraction generate clear figure and obtain characteristic value-chord length and the intercept of the longitudinal axis to calculate dam deformation degree.System
Including monitor controller and centralized manager, firm end is arranged outside dam body in centralized manager, if laser is emitted and direct projection to
Dry equidistant monitoring point, and a datum mark monitor is respectively set at each monitoring point, as shown in Figure 1.When work
To datum mark monitor a series of control commands occur for host computer, allow to open laser in the case that obtaining each monitor always
Device, while emitting shooting image command to monitor.It is finished through image procossing and characteristic value is stored in EEPROM, host computer is waited for have
Close order.Centralized manager can realize GPRS or RS485 data communications with host computer, and dam deformation data are for statistical analysis
Digital intelligent safety management can be realized, prevent trouble before it happens, avoid dam body from the accidents such as collapsing and occur.
But in above-mentioned two patent of invention, the laser via baffle of Centralized Controller is horizontal by laser via baffle
Control mechanism and laser via baffle vertical control mechanism are moved and are fixed, (the object when baffle is by foreign impacts
Shock or strong wind), baffle is easy to damage, and leads to water inlet or dust in Centralized Controller babinet, influences Centralized Controller
Operation cause can not accurate measurements reservoir dam.
