Embodiment 1

[0029] A liquid level detection and adjustment method designed based on a single-chip microcomputer using solar power supply, comprising the following steps:

[0030] 1) When the power supply starts, the sunlight shines on the photovoltaic panel, and the photovoltaic panel converts the light energy into electrical energy, and then further collects and transmits the electrical energy to the booster circuit through the internal circuit, and the booster circuit boosts the voltage and performs rectification and filtering , the DC voltage after rectification and filtering is supplied to the central processing unit through the power supply circuit, so that the central processing unit starts to work;

[0031] 2) Acquisition and detection of liquid level information. A pressure sensor for testing the liquid level value is placed inside the liquid. The liquid acts on the surface of the pressure sensor and generates a pressure value. The pressure sensor converts the pressure value into a...

Embodiment 2

[0036] This embodiment is further optimized on the basis of the above embodiments. Further, in order to better realize the present invention, when the power supply is started, it also includes a backup power supply mode, and the backup power supply mode is generated by photovoltaic panels. The abundant electric energy will be stored in the battery pack through the power control circuit. When the light intensity is not enough to generate electricity or at night, the battery pack will release the electric energy stored inside, and after the power control circuit transforms and stabilizes the voltage, it will be supplied to the central processing through the power supply circuit. device.

Embodiment 3

[0038] This embodiment is further optimized on the basis of any of the above-mentioned embodiments. Further, in order to better realize the present invention, it also includes a background control step. The background management center will issue a collection instruction to the central processing unit, and the central processing unit will Process the collection instruction and complete corresponding operations such as liquid level collection, liquid level adjustment, and liquid level optimal value setting according to the collection instruction.

Abstract

The invention discloses a liquid level detection and adjustment method with solar power supply based on a single-chip microcomputer. The method comprises the following steps of power supply starting in which a photovoltaic panel converts luminous energy into electric energy, and electric energy is supplied to a central processor via a power supply circuit so that the central processor starts working; liquid level information collection and detection in which a pressure sensor converts a pressure value into an analog voltage signal and outputs the analog voltage signal; level switch; central control in which the central processor receives the digital level, processes and analyzes a result, and then compares the result with a preset value to form a control instruction; and liquid level adjustment in which the central processor emits the control instruction and transmits the control instruction to a control circuit, the control circuit converts the control instruction into an electric signal which can be executed by a solenoid value, and the solenoid valve is open and closed to adjust the liquid level value. Power is supplied to a liquid level detection and adjustment system in the solar power supply manner, sensor technology is utilized, and according to the liquid level detection and adjustment method, non electric quantity information is converted into electric quantity information with the liquid pressure intensity principle.

Description

technical field [0001] The invention relates to the fields of sensor application technology, clean energy utilization technology, etc., and specifically relates to a liquid level detection and adjustment method based on a single-chip microcomputer design using solar power. Background technique [0002] The characteristics of the internal pressure of a liquid are: the liquid is subjected to gravity; the liquid has fluidity. Because the liquid is affected by gravity, there is a pressure inside the liquid caused by the gravity of the liquid itself. From the experimental results and theoretical deduction, it is shown that this pressure is equal to the product of the mass per unit volume of the liquid and the depth of the liquid. That is, p=ρgh (where g≈9.8 Newton / kg is the local acceleration of gravity). According to the formula, the pressure inside the liquid is related to the depth, the depth increases, the pressure also increases. [0003] The formula of liquid pressure is:...
