Based on SCM alexipharmic ark control design Abstract:At present, worldwide, with microelectronics technology, a computer and communication technology as the forerunner, take the information technology and the information industry as the center of information revolution is in the ascendant. In order to make our country as quickly as possible economic informatization, catch up with the developed countries, we must accelerate the development level of our country's information technology and information industry. But how computer technology and practical application is more effective combination and effective play its role is the scientific community's hottest topic, also is the current computer application in active unprecedentedly field. This paper mainly introduces a made by AT89C51 alexipharmic ark control circuit. It mainly includes the power supply circuit, the electricity reset circuit, crystal oscillator circuit, switch control circuit, electric heat pipe circuit, alarm circuit and other parts. In this paper the circuit structure and work principle of a detailed introduction. Circuit after the operation, it can automatic timing control alexipharmic ark of plus electric heating tube and power outages, timely effectively completed to rack tableware or other articles disinfection job. Has the circuit is simple, easy to make, use agile, etc. Through the change circuit, can further understanding to the application of SCM circuit function expansion and instructions application skills.
