Abstract
The invention provides a height measuring and early warning method for a geotube for sludge dewatering, which solves the problems that the height of the geotechnical pipe pocket in a filling process is difficultly monitored and measured by a staff all the time due to the changing height and the increased volume of the geotechnical pipe pocket and the like. A working wavelength of 635nm is used by a laser sensor (insight-60), a measuring range of the laser sensor is 0.05-60m and the typical precision of the laser sensor is +/-1.5mm. The data is transmitted by using Bluetooth and an analogue signal of an early warning program is generated. The height measuring and early warning method using the laser sensor can be continuously performed, and the early warning process can be effectively carried out while the height is measured accurately, so that the potential safety hazard in a construction site is greatly reduced.
Description
Technical field
The present invention relates to the remote sensing technical field, relate to particularly that a kind of geotextile tube bag that is used for sludge dewatering is highly measured, the untouchable laser-measured height method of early warning.
Background technology
At present, the geotechnological pipe racks height in the filling is difficult to monitoring constantly.Because the geotechnological pipe racks height when filling constantly promotes, and volume is excessive, make survey crew be difficult near measuring.In addition, after arriving safe altitude, fill like untimely stopping, geotextile tube has and possibly break, because job site personnel is more, can cause more serious construction accident.Therefore, the timely early warning of geotechnological pipe racks safety packed height is the key factor that guarantees construction safety.
Highly measure and use stadimeter usually, more is triangular measuring transducer, ultrasonic sensor.
Triangular measuring transducer can be worked under the situation that color of object changes preferably, still, when fixing or target is too bright at angle on target, its performance predictability variation.In addition, the general range of triangular measuring transducer is only limited in the 0.5m.
Ultrasonic sensor is to run into the characteristic that barrier reflects according to ultrasound wave to measure.Wherein, the target of ultrasound examination must be in and the transducer vertical orientation, and the drift angle is not more than 10 °.All can cause corresponding error in occasion windy, that thermograde is bigger.
Therefore; The method that we have selected for use untouchable laser sensor (insight-60) to measure, this method is accurately convenient, and precision is higher; Measuring distance length no matter; Equally quick accurate measurement, and have data storage and data output (the computer output interface is arranged) function, be convenient to the storage and the processing of measurement data.Not only volume is little, from heavy and light, is convenient to the reviewer and carries, and is simple to operation, significantly reduced Measuring Time, improved the accuracy of measuring.
The method of typical case's laser ranging has impulse method, phase method, interferometric method etc., and these methods respectively have characteristics, are applied to different measurement environment and field of measurement respectively.The measurement range of impulse method from tens meters to kms up to ten thousand, precision is a rice magnitude, is mainly used in scientific research and military field, such as the range observation of the ground moon etc.; The measurement range of phase method from several meters to several kms, precision reaches a millimeter magnitude, is mainly used in geodetic surveying and engineering survey; Distance about interferometric method general measure centimetre, precision is mainly used in the forecast of geologic hazard up to micron dimension.Survey in the high work at geotechnological pipe racks, we have selected for use phase type laser sensor (insight-60) to measure and early warning.
Summary of the invention
The objective of the invention is to the geotextile tube bag in the filling, highly the moment changes, and volume increases, the people monitors problems such as measurement for being difficult to the moment, a kind of non-contact laser relative height measurement that provides and the method for early warning.
The present invention uses a kind of new pattern laser sensor (insight-60), and not only volume is little, in light weight, and need not cooperative target and can reach a millimeter class precision.
The present invention adopts following technical scheme: adopting self-supporting standard elevating lever is base, on connect L type support, can fix two laser sensors, a horizontal positioned, vertical placement, and guarantee to penetrate light source on same surface level.Through setting, so that reach the purpose of early warning security height to simulating signal.Through horizontal range control, can record the height that actual geotextile tube bag is filled.This device to terminal, can write down corresponding data through the Bluetooth wireless transmission data automatically.
Above operations all can realize the real-time automatic monitoring measurement, and each association relies on Bluetooth transmission to main frame, devices such as reduced data line.Increase the operability of field and working-yard.
Aforesaid a kind of geotextile tube bag height measurement method that is used for polluted bed mud, described self-supporting standard elevating lever overall height can reach 15 meters, and vertical load 50kg can bear stable state wind speed strong gale.
Aforesaid a kind of geotextile tube bag height measurement method that is used for polluted bed mud, described laser sensor uses the operation wavelength of 635nm, and measurement range is 0.05-60m.Typical accuracy is ± 1.5mm.Use the Bluetooth transmission data, and the simulating signal of early warning program is arranged.

Embodiment
Setting geotextile tube bag mid point is horizontal laser light sensor predeterminable range A (m) to the elevating lever distance.The use elevating lever rises, and after the altitude information that vertical laser sensor is measured is safe altitude, stops.The geotextile tube bag promptly can begin to fill, and along with the rising of geotextile tube bag, the horizontal laser light sensor can receive reflection ray, and when measured data were predeterminable range A (m), the beginning early warning was reminded.Stop time-delay to occur owing to fill in the engineering, be decided to be safe altitude so actual geotextile tube bag highly differs.The elevating lever that can rise makes when the horizontal laser light sensor records distance once more for A (m), writes down data that vertical laser sensor is surveyed automatically.At this moment, these data are the true altitude that this geotextile tube bag is filled.Because the geotextile tube bag is filled and is generally always had 4 layers, only need to continue the rising elevating lever, corresponding adjustment preset data gets final product.
Claims (6)
