Embodiment Construction

[0010] Below in conjunction with accompanying drawing and embodiment the patent of the present invention is further described.

[0011] figure 1 , press the reset button through the keyboard, the metal moving probe 4 rises to the position of the photoelectric sensor 3, wait for the desired water level to be set, after setting the water level, press the start button, the metal moving probe 4 reaches the set water level, figure 2 , through the P3.6 port 14 detection level of the single-chip microcomputer, if it is low level, it indicates that the water in the water tank is insufficient, turn on the water inlet pump 8, and the water pump stops water intake when the water in the water tank reaches the set water level, otherwise the opposite . When the water in the water tank descended, the metal moving probe 13 descended with the decline of the water level, and carried out tracking water level control. After the water in the water tank was all used up, the single-chip microcom...

Abstract

The invention discloses a continuous water-level control system based on a singlechip, which is used for realizing continuous control and water level tracking. The system mainly comprises circuits such as a singlechip controller module, a stepping motor driving module, a water level detection module, a water inlet/outlet module and the like, wherein the stepping motor is a digital control motor which is used for converting electric pulse into angular displacement, i.e., the stepping motor rotates by a fixed angle along a set direction once a pulse signal is given. A water level signal is acquired by using a metal bar and the electric conductivity of water, the output level of a singlechip port is used for controlling a relay to control a water pump, the steps of the stepping motor are counted, and a practical water level in a water tank can be measured in real time through a simple digital model, so that continuous control and water level tracking are realized, and the water level is displayed in real time through a liquid crystal. The scheme has the characteristics of novel design thought, simple principle, easiness in realizing, high accuracy and the like; and the control system has important signification to the improvement of the industrial automation level and the living water quality.

Description

technical field [0001] The invention relates to a novel energy-saving and environment-friendly water level control system, in particular to an industrial process control for automatic detection and control of the water level. Background technique [0002] Water level control technology has broad application prospects in the field of production and life. In the field of production, the automatic detection and control of water level is a key technology of industrial process control, which is of great significance for improving the automation level of industrial process control. In the field of life, with the increasingly prominent contradiction between human beings and the surrounding living environment, people are paying more and more attention to the issue of water resources. In our country, whether it is residential quarters in cities or household users in vast rural areas, water pumps are often used to pump water for water supply. In the past, this water supply method was...
