Technical Field

The invention relates to a water depth measuring device, in particular to an electronic sounding rod.

Background

The sounding rod is one of the main tools for measuring water depth, and is generally a calibrated and readable scale rod made of metal or other materials and provided with a chassis. The scale interval of the measuring rod needs to consider the size of the measured water depth and the water surface wave amplitude, the regional distribution of the measuring rod body is recommended to be determined according to a table from small to large, and the scale mark is obvious and clear no matter wet water exists. When the device is used, the depth measuring rod is vertically inserted into water, and the current water depth value is read through the scales. The depth measurement rod has the characteristics that the distance between the river bottom and the water surface is directly measured, the method is simple and direct, but the flow velocity is increased along with the increase of the depth, the observation is difficult to increase, and the depth measurement precision is difficult to ensure, mainly because the depth measurement rod is difficult to keep vertical due to the action of underwater water flow; the river bottom is difficult to accurately judge; large water surface floating, etc.

Disclosure of Invention

The invention aims to provide an electronic depth sounding rod which can automatically measure the depth of water and send data to a receiving device, is convenient to use and can quickly measure the depth.

In order to achieve the purpose, the invention adopts the following technical scheme:

An electronic depth sounding rod comprises a rod body, wherein stainless steel contacts are arranged on the rod body at equal intervals and are connected with a contact position judging and processing circuit, and the contact position judging and processing circuit adopts a CMOS decoding and encoding circuit; the contact position judging and processing device comprises a rod body, a contact position judging and processing circuit, a three-dimensional angle sensor, a three-axis accelerometer, a control unit, a wireless transmitting circuit, a battery and a charging circuit, wherein the rod body is internally provided with the three-dimensional angle sensor and the three-axis accelerometer, the contact position judging and processing circuit, the three-dimensional angle sensor and the three-axis accelerometer are connected with the control unit, the control unit is also connected.

Preferably, the control unit adopts an MSP430 single chip microcomputer.

Preferably, the rod body is a plastic pipe, and the stainless steel contact is arranged on the outer wall of the plastic pipe.

Among the above-mentioned technical scheme, set up the stainless steel contact on the body of rod and can measure the degree of depth of intaking of the body of rod, the body of rod length of wading into water promptly, three-dimensional angle sensor can measure the inclination of the body of rod for the horizontal plane, the state that the body of rod touched the end can be experienced to the triaxial accelerometer, the control unit begins to measure the body of rod length of wading into water when the body of rod touched the end, and the body of rod relative to the angle of inclination of horizontal plane that measures according to three-dimensional angle sensor, then can calculate out the vertical depth of water by the control unit according to trigonometric function relation, and send the depth of water. The depth rod does not need to keep the rod body vertical, can better detect the water bottom and is very convenient to use.

Detailed Description

The invention will be further explained with reference to the accompanying drawings:

As shown in fig. 1, the electronic depth measuring rod comprises a rod body 1, wherein a plurality of stainless steel contacts 2 are arranged on the rod body 1 at intervals, the stainless steel contacts 2 are connected with a contact position judging and processing circuit, and the contact position judging and processing circuit adopts a CMOS decoding and encoding circuit. The three-dimensional angle sensor 3 and the three-axis accelerometer 4 are arranged in the rod body 1, the contact position judging and processing circuit, the three-dimensional angle sensor and the three-axis accelerometer are connected with a control unit MSP430 single chip microcomputer (not shown), the MSP430 single chip microcomputer is further connected with a wireless transmitting circuit, a battery and a charging circuit, the charging circuit is connected with a solar cell panel 5, and the solar cell panel is arranged at the top of the rod body. Usually, the rod body is made of a plastic pipe, and the stainless steel contact is arranged on the outer wall of the plastic pipe. After the rod body goes deep into water, part of the stainless steel contacts are immersed into the water and are short-circuited, and the contact position judgment and processing circuit detects the short-circuited contact position, so that the immersion length of the rod body into the water can be known, and the vertical depth of the water can be calculated through a trigonometric function relation. The three-dimensional angle sensor can measure the angle between the rod body and the horizontal plane, and the three-axis accelerometer can sense when the rod body is contacted with the bottom of the river channel through the change of the acceleration of the rod body.

The embodiment is only an illustration of the concept and implementation of the present invention, and is not a limitation, and technical solutions without substantial changes are still within the protection scope under the inventive concept.
