Abstract
In this paper,it’s mainly about the detailed design and of the Automatic toothpaste machine control systems.Analysis of automatic toothpaste machine required to achieve the functional requirements; Understanding the same type of toothpaste machine with the working principle, basic structure, composition and function of the system; Knowing some basic usage of electronic components and the components of selection method, and how to achieve to the Realization of systems.
Automatic toothpaste machine is a simple product of mechatronics,it includes infrared technology,SCM technology,relay,motor technology and so on.Through the control of infrared sensors,trigger the motor’s working,then control the etrusion volume of the toothpaste through the trip of the motor.And this is the main technical route of the Domestic-automatic toothpaste machine.
The design includes the choice of the microcontroller, the circuit connection and the program. It has detailed instructions of the circuit master plan and program in this paper, The design consistent with the current theme "low-carbon life" ,and as much as possible to save the life of a variety of resources.
