A method for automatic detection and tracking of a water level aims at not only being capable of measuring the water level but also being capable of tracking the water level in real time. The invention firstly provides a set of automatic water level detection and tracking device which comprises water level detection probes, probe wires, an alternating current excitation circuit, a signal detection and processing circuit, a single chip microcomputer, a stepping motor, a connecting gear, a lead screw, a lead screw base, a lead screw, an instrument stand and a mounting table. The water level detection probes are fixed perpendicular to the horizontal plane, the top ends of the water level detection probes are level with one another, the bottom ends of the water level detection probes are arranged in a stair-stepping mode. The signal detection and processing circuit is connected to the single chip microcomputer which is connected to the stepping motor. A rotating shaft of the stepping motor is connected to the connecting gear which is engaged with the lead screw. The lead screw base is connected to the instrument stand, and the automatic water level detection and tracking device is fixed on the mounting table. Water level measurement is performed according to weak electric conduction characteristics of water, and water level tracking is achieved according to the on-off state of the three water level detection probes of T1, T2 and T3.
Description
technical field [0001] The invention relates to a water level detection and tracking method, which belongs to the technical field of automatic detection, in particular to a device capable of detecting and tracking the water level. Background technique [0002] In many scientific research projects, experimental projects and hydrological observations, it is not only necessary to detect the water level in real time, but also to measure parameters such as flow velocity and temperature changes at different depths of the water surface and below the water surface. For example, in the thermal power plant's physical model experiment of thermal drainage, it is necessary to accurately measure the water level, the flow velocity of the water surface, the temperature distribution of the water surface and different depths below the water surface, in order to study the hydrothermal characteristics of the thermal drainage, which requires the flow rate instrument , The temperature gauge can m...
