Design Of Monitoring System Control Module Based On MCU

As China's reform and opening up and socialist modernization drive to speed up the pace, Factories and office buildings of enterprises are becoming increasingly large scale. And neighborhood has become an increasingly large. Traditional security measures are to build high walls and supplemented by regular patrols of security personnel. This is not only time consuming and can not do a full rage of monitoring. If you had not been able to find illegal invasion and deal with timely, cameras were installed in a secure area in order to protect property and personal safety. Real-time monitoring images can be sent to the security control room in order to enhance the rate of dealing with emergency and to protect property and personal safety.This work includes the design of code mixer and decoder. This article briefly introduces the principle of monitoring system and gives the location of the code mixer and decoder in the control system schematic diagram. The design of code mixer and decoder are all based on STC microcontroller. Code mixer is used to solve the operation conflict when the digital hard disk recorder and matrix switching host send commands to the decoder at the same time. Decoder is used to control the head and lens.The content of this paper is to discuss the above.The chapter one outlines the significance of monitoring system and introduces MCU development process.The chapter two elaborates on STC microcontroller and gives the monitoring system diagram.The chapter three shows Control system design principles, anti-interference design and debugging methods.The chapter four elaborates on code mixer and decoder hardware design.The chapter five shows mixer and decoder code program flow chat.
