Embodiment 1

[0021] Embodiment 1. Substance leakage control method

[0022] The substance leakage control method in this example is a method of controlling the stepping motor through a single-chip microcomputer to accurately control the leakage amount of a certain substance: the substance leakage control method described is to use a single-chip computer software program to control the speed and rotation angle of the stepping motor. A method of precisely controlling the amount of leakage of a substance. The method for controlling the rotation speed and the rotation angle of the stepping motor is a method of controlling the rotation speed and the rotation angle of the opening disc through the stepping motor. As for the opening disc, the center of the disc is fixed on the drive shaft of the stepping motor, and there is a fan-shaped opening area formed by a set center angle on the disc. The fan-shaped opening angle described in this example is 15 degrees-180 degrees. The upper plane of the o...

Embodiment 2

[0023] Embodiment 2. Substance leakage control method

[0024] The difference between the substance leakage control method in this example and the substance leakage control method in Embodiment 1 is: according to the size of the substance, a long-necked funnel with a suitable lower port diameter can be selected, and a substance can be selected first, such as soybeans with a diameter of 8 mm. As an example, select a plastic long-necked funnel with a diameter of 1 cm and a length of 30 cm, select a disc made of plastic material with a fan-shaped gap, the radius of the disc is 10 cm, and the fan angle is temporarily taken as 60 degrees. The program sets an initial rotation speed of the stepping motor, and sets an alarm clock time, and sets the stepping motor to rotate only one circle after reaching the alarm clock time, and then staggers the opening part of the opening disc from the lower nozzle of the funnel, after downloading the program , turn on the power supply, after the st...

Embodiment 3

[0025] Embodiment 3. Substance leakage control method

[0026] The difference between the substance leakage control method in this example and the substance leakage control method in Embodiment 1 and Embodiment 2 is: if the stepper motor rotates one revolution, the leakage of soybeans is 10 grams, and the required soybeans are 30 grams, then the program can be modified , Appropriately reduce the rotation speed of the stepping motor so that 30 grams of soybeans are leaked out every time the stepping motor rotates. The rest of the material leakage control method of this example is the same as that described in Embodiment 1 and Embodiment 2, and will not be repeated.

Abstract

The invention discloses a substance leakage control method, which belongs to the technical field of electronic information control. The method is such a method that controls a stepping motor through a single-chip microcomputer to accurately control the leakage amount of a certain substance and that controls the rotating speed and the rotating angle of the stepping motor through a single-chip microcomputer software program to accurately control the leakage amount of a certain substance. The advantages of the invention are as follows: the method, compared with other quantitative substance-obtaining methods or devices, uses fewer chips, so an entire device employing the method is small in size, simple in principle, exquisite in structure, low in power consumption and low in cost; and the method is extremely wide in application range, is suitable for various substances of different states (such as granular or powdery), exhibits strong functions through the single-chip microcomputer and the software thereof, enables the leakage amount of substances to be accurate, and is thus worth of being adopted and popularized.

Description

technical field [0001] The substance leakage control method disclosed by the invention belongs to the technical field of electronic information control, and specifically relates to a method for precisely controlling the quantitative leakage of substances through the rotation of an opening disc by controlling a stepping motor by a single-chip microcomputer. Background technique [0002] Stepper motor is a common electromechanical product, and its control application has been widely used in industrial, civil, commercial and other fields. For the quantitative and timing leakage control of substances, the common method is to put the required amount of substance each time in a fixed container, and control the amount of the required leakage substance by leaking the amount of a container each time. This method The amount of material in each container needs to be loaded in advance, which is too complicated, and the amount of loading is very limited, which is very inconvenient. Abro...
