Abstract

The utility model provides a deep-water high-accuracy sensor device which belongs to the sensor technical field for liquid level measurement. The utility model fixes two hydraulic pressure sensors with good consistency on a certain high difference under a water area for monitoring, and guarantees that the other sides of measuring surfaces of the two sensors keep correspondence with the atmospheric pressure, that is, the other sides of the measuring surfaces of the two sensors are communicated with air of water surface, thereby forming a measuring device which is not affected by the atmospheric pressure. The device can be used to form a water level measuring system of low cost and form a set of accurate and efficient automatically measuring system in conjunction with the prior embedded computer technology, computer network, GPRS network or other technologies, thereby achieving the whole river basin real-time monitor and water situation report of rivers. Therefore, the utility model provides a basic measuring means and support for the water situation automatic monitoring.

Description

Deep water position high-precision sensing apparatus
Technical field
The utility model relates to the sensor device that a kind of high-precision deep water level measuring is used.
Background technology
Present river, the river, the lake, most important level measuring in the hydrographic survey in storehouse, the hydraulic department measuring error requires to reach ± 1cm, current in the river, the river, the lake, when the main adopts pressure sensor in scenes such as storehouse carries out level measuring, and pressure transducer measurement water level is P=ρ gh according to theoretical foundation mainly, by formula P=ρ the gh static pressure of water and the density of water as can be known, acceleration of gravity, the height of water level is relevant, converse water level value according to this formula, and the water level of measure field is because environmental change, such as temperature, density, degree of purity, variations such as place and then make ρ, g changes, because the unpredictability of this change, thereby utilize this method to be difficult to reach the measuring error requirement of hydraulic department.In order to guarantee measurement accuracy, generally all adopting artificial observation is that main mode is carried out, and has greatly influenced the efficient and the informationalized development of regimen of water regime monitoring.Though a lot of relevant automatic measurement solutions are arranged, all can't ensure the deep water position, the measurement result under the situations such as water level wide fluctuations.
Summary of the invention
The purpose of this utility model provides problems such as a kind of atmospheric pressure interference that can overcome, fluid density fluctuation, provides a kind of sensor device for carrying out the dark level gauging of high precision.
The purpose of this utility model is achieved in that a kind of deep water position high-precision sensing apparatus, comprise sensor 1 and sensor 2, sensor 1 directly contacts with hydraulic pressure with sensor 2 one ends, the other end communicates with atmosphere by the air duct 4 with cable 3 one, keeps certain height poor between sensor 1 and the sensor 2.Sensor 1 and sensor 2 adopt parameter characteristic basic identical.
Deep water provided by the utility model position high-precision sensing apparatus utilizes to have better conforming two hydraulic pressure sensors, by they being fixed on the difference in height of determining under the waters to be monitored.And opposite side and the atmospheric pressure of guaranteeing the measurement face of these two sensors be consistent, and just by pipeline opposite side communicated with the air of the water surface, thereby constitute a measurement mechanism that not influenced by atmospheric pressure.Utilize this device can constitute a water level measurement system cheaply, cooperate technology such as current embedded computer technology, computer network or GPRS network can constitute the very accurate and automatic measurement system efficiently of a cover, realize that the monitoring in real time of full basin and the regimen of rivers reported.Thereby for the automatic monitoring of regimen provides basic measurement means and support.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model adopts following structure: a kind of deep water position high-precision sensing apparatus, comprise sensor 1 and sensor 2, sensor 1 directly contacts with hydraulic pressure with sensor 2 one ends, the other end communicates with atmosphere by the air duct 4 with cable 3 one, keeps certain height poor between sensor 1 and the sensor 2.Sensor 1 and sensor 2 adopt parameter characteristic basic identical.
Principle of the present utility model is: sensor 1 and sensor 2 have consistance preferably, with they logical being fixed on the height difference H of determining under the waters to be monitored, and opposite side and the atmospheric pressure of guaranteeing the measurement face of these two sensors are consistent, just opposite side is communicated with the air of the water surface, thereby constitute a measurement mechanism that not influenced by atmospheric pressure by pipeline 4.By to the obtaining of two sensor measurement data, and the difference of their relative positions can calculate the water surface elevation value.And because these two sensors are under the same environment, suffered extraneous factor influences basically identical, when the parameter characteristic basically identical of two sensors, then can utilize its difference to reduce sensor and be subjected to extraneous factor to influence the error of generation.When relevant measurement scheme matches, can obtain than independent measurement hydraulic pressure precision high many measurement result.Import embedded computer, computer network or GPRS network into by the data that cable 3 obtains sensor, can constitute the very accurate and automatic measurement system efficiently of a cover, realize that the monitoring in real time of full basin and the regimen of rivers reported.Thereby for the automatic monitoring of regimen provides basic measurement means and support.
