Description
Technical field
The present invention establishes and a kind of monitoring ultrasonic appearance, just relates to a kind of monitor that is used to monitor building member and affiliated facility horizontal shift specifically.
Background technology
When engineering construction and various disaster monitoring, the displacement of building member and affiliated facility is one of content of essential monitoring.Traditional monitoring instrument needs manual operations, and artificial reading has increased labour intensity, and accuracy of instrument is limited, then is difficult to reach requirement for the observing and controlling project that high-precision requirement is arranged.And as far as some high accuracy displacement sensor, its higher price has limited its large-scale application again, and can not reflect the variation with the recording level displacement in real time.
Ultrasonic ranging is a kind of non-contact detection mode; In use do not receive factor affecting such as illuminance, electromagnetic field, measured object color; Its information processing is simple; Speed is fast, and cost is low, in robot obstacle-avoiding and location, aspects such as vehicle self-navigation, level gauging have had widely and use.The non-contact ultrasonic stadimeter is according to pulse return pattern work, runs into according to ultrasound wave that characteristic that barrier reflects measures.Ultrasonic transmitter picks up counting in emission to a certain direction emission ultrasound wave simultaneously, and ultrasound wave is propagated in conductive medium, runs into barrier in the way and just returns immediately, and ultrasonic receiver receives that reflection wave just interrupts stopping timing immediately.Through running into the echo that barrier reflects after the emission of continuous detection generation ripple, launch ultrasound wave and the mistiming T that receives echo thereby measure, obtain distance L then.Basic range finding formula is:
L=(△t/2)*C （1）
In the formula: L---the distance that survey;
The time interval between △ t---transmitted wave and the reflection wave;
The velocity of propagation of C---ultrasound wave in conductive medium after the velocity of sound is confirmed, as long as measure the time that ultrasound wave comes and goes, can be tried to achieve L.
Summary of the invention
The present invention is a instrument that can the automatic monitoring object horizontal shift of real-time high-precision that utilizes that ultrasonic technology develops.As conductive medium, can realize the measurement of pinpoint accuracy through liquid.Real-time monitoring simultaneously is beneficial to the timely warning to danger, fails the hidden danger of in time reporting to the police when having eliminated dangerous the generation.
The present invention realizes goal of the invention through following technical scheme:
A kind of ultrasonic level displacement monitor; Comprise the ultrasonic emitting acquisition instrument; Also comprise telescopic corrugated tube, and the spring overcoat that corrugated tube outside, is provided with, casing, intercommunicating pore, reach ultrasonic probe, said ultrasonic emitting acquisition instrument is installed in the casing; Said ultrasonic emitting acquisition instrument is provided with ultrasonic probe; Said corrugated tube one end sealing, the other end is connected with said box sealing and makes ultrasonic probe be in the port of corrugated tube, and said corrugated tube is provided with intercommunicating pore.
A kind of monitoring method of ultrasonic level displacement monitor may further comprise the steps:
(a) at first adjust casing one end of ultrasonic level displacement monitor and the distance between the tested member, make the other end of corrugated tube and spring overcoat can be close to member, mounting ultrasonic probe institute does not at one end move;
(b) secondly in corrugated tube, fill with liquid, fill with the back corrugated tube and be close to member, and still can freely stretch in the horizontal direction, the scalable value of corrugated tube is greater than the maximum possible value of member horizontal shift;
(c) connect the ultrasonic emitting acquisition instrument then; Open the monitoring of ultrasonic emitting acquisition instrument; The measured displacement data in real time records in the data acquisition and processing (DAP) system of ultrasonic emitting acquisition instrument, the initial value when the horizontal shift value of a certain moment member begins to test for this moment ultrasonic investigation value deducts ultrasonic instrument;
(d) when horizontal shift exceeded the warning value that is provided with in advance, instrument can write down and send warning automatically, so that in time take control measure.
The advantage of invention:
The present invention is through utilizing liquid as conductive medium, can solve the requirement to transmission medium of high frequency, high-precision ultrasound wave transmitting device, realizes high-acruracy survey.This device utilizes corrugated tube in axial contractile properties, makes corrugated tube with the displacement of required monitoring member, moves the displacement that the distance of an end can draw member through monitoring fixing ultrasonic probe and the corrugated tube that moves.Utilize connecting pipe principle compensation simultaneously or overflow the liquid in the corrugated tube,, satisfy ultrasonic high accuracy monitoring condition and reduce systematic error to realize in the corrugated tube purpose of full of liquid all the time.The effect of spring overcoat can be protected corrugated tube on the one hand, and the constraint corrugated tube is in radially variation; On the other hand, spring overcoat can closely contact with member, constitutes spring, the tested member system consistent with the corrugated tube displacement, truly reflects the displacement situation of tested member.This instrument test precision is high, utilizes liquid can reach the micron order precision as transmission medium, and the monitoring overall process realizes real time implementation and robotization, and this system does not have specific (special) requirements to component surface simultaneously, be easy to use, and cost is lower.
