Capacitance type flexible electronic tide staff

Abstract

The invention discloses a capacitance type flexible electronic tide staff. The tide staff comprises a flexible tide staff body serving as a sensor element and a processing circuit, wherein the flexible tide staff body comprises a plurality of flexible capacitance plates which are arranged in rows and tide staff supporting bodies which are embedded in the flexible capacitance plates and is used for improving the strength of the tide staff body and preventing errors due to the telescopic size of the length direction of the electronic tide staff, the flexible capacitance plates and the processing circuit are connected through a circuit and are used for achieving the function of the water level measurement, and the flexible capacitance plates are in a structure that adjacent two capacitance plates are arranged in the staggered mode. The tide staff is simple in structure, convenient to use, high in resolution power, little in accumulated error and large in water level measuring range. The tide staff can be bent, flexible capacitance plates serve as sensor elements and can be used for analog measurement and digital measurement, the high resolution is achieved through the analog measurement of the capacitance plates, the error is reduced through the digital measurement of the capacitance plates, and the tide staff is made of flexible materials.

Description

technical field [0001] The invention relates to a capacitive flexible electronic water gauge. Background technique [0002] At present, the liquid level measurement tools in the prior art include capacitive liquid level gauges, electronic water gauges or electrode type liquid level gauges; there are the following defects: [0003] 1. Due to the limitation of the measurement principle of the capacitive liquid level gauge, the range of the high-precision capacitive liquid level gauge is very small, which cannot meet the needs of a large range. [0004] 2. The measurement of the electronic water gauge depends on the contact between the electrode and the water surface. The higher the resolution or the larger the range, the more electrodes there are, and it is difficult to increase the range. The scale body of the electronic water gauge is made of rigid materials. Due to the limitation of transportation conditions, the length of the single body of the electronic water gauge is v...
