Abstract
This utility model provides the device of a kind of static level level measuring based on ultrasonic ranging principle, including liquid container, sensor storehouse, ultrasonic sensor, front-end processing circuit plate.This utility model relates to the measurement of the civil engineering structure such as vertical displacement of foundation ditch, tunnel, subway etc., it is intended to avoids existing static liquid level to be brought this defect of measurement error by ball float and guide rod, is greatly improved in the certainty of measurement to works.
Description
Technical field
This utility model relates to the device of a kind of static level level measuring based on ultrasonic ranging principle.
Background technology
At present the level measuring method of static level generally by measure the change of hydrostatic level self liquid level obtain by
Survey the vertical discrepancy in elevation of object, react level change by the height change of the ball float contacted with liquid level.Install on ball float guide rod
Sensor, guide rod following water-level lifting, its changing value is converted to the signal of telecommunication, is sent to data collecting system by sensor.
This method obtaining liquid level change by measuring the change of float displacement can produce error greatly:
1. the error that ball float infiltration produces: ball float contacts with liquid level, and liquid forms semilune around ball float, and ball float is upper and lower
Move and all can be stained with liquid, thus bring measurement error；
2. the error that guide rod tilts, bar wall friction produces: ball float, in upper and lower change process, occurs guide rod inclination, guide rod
With the friction of sidewall, these situations all can affect the accuracy of measurement, produces systematic error；
3. the error that buoyancy change produces: the change of temperature and atmospheric pressure can bring the variable density of liquid, and is non-thread
Property, thus cause the buoyancy suffered by ball float to change, and then bring the error of ball float height change.
Summary of the invention
In order to solve above-mentioned technical problem, the utility model proposes a kind of static level based on ultrasonic ranging principle
The device of level measuring, with this defect of error avoiding existing static level monitoring system to be brought by ball float, a kind of nothing of design
The contactless ultrasound wave static leveling device of ball float, has bigger in the vertical displacement certainty of measurement to works
Improve.
Ultrasound wave static level level measurement device described in the utility model includes: liquid container, sensor storehouse, ultrasonic
Wave sensor, front-end processing circuit plate, described sensor position in storehouse is arranged on sensing in the upside of liquid container, ultrasonic sensor
The bottom centre in device storehouse, the inside in sensor storehouse is provided with front-end processing circuit plate, and sensor storehouse upper side wall is provided with cable connector,
The sidewall of liquid container is provided with liquid container passage, and the downside wall of liquid container is provided with fluid connection mouth.
This utility model also proposed a kind of method of static level level measuring based on ultrasonic ranging principle, described
Ultrasound wave static level water level measurement method make use of in connected container, liquid always seeks the level with identical potential energy
Principle, measures the vertical drop between each measuring point.A ultrasound wave static level level measuring is set up at relatively stable point
Device, as datum mark, all sets up a ultrasound wave static level level measurement device in each position of several tested points,
Then with fluid connection pipe by quiet with several ultrasound wave measuring point for the ultrasound wave static level level measurement device of datum mark
Power level level measurement device connects at respective fluid connection mouth.When tested point vertically produces displacement, the change of liquid level
Amount can be obtained by ultrasonic sensor range measurement principle.
The utility model has the advantages that compared with existing hydrostatic leveling technology, this utility model use based on super
The static level level measuring of sound ranging principle is contactless static level level measuring, and it is not in use by conventional static water
The ball float used in locating tab assembly system, it is to avoid because ball float infiltrates, ball float guide rod tilts, bar wall friction, temperature and air buckling
Change the error brought, improve the certainty of measurement of works vertical displacement largely.
