基于PLC的霓虹灯广告屏控制系统的设计

ABSTRACTNeonThe neon ad screen is one of the means the company advertises its ownimage and product.Strong mobility,low energy consumption,economical utility,long life span,good effect,flexible manufacturing,and variety of colorsIn this paper,the screen structure and operation principle of neon advertisementare described,and the general-purpose of the programmable controller is high,theprogram control is easy,and the application range is wide,the strong interferenceprevention ability,and the high reliability,etc.are controlled,and the control systemof the screen of the advertisement of the neon advertisement is described The designof the temp based on the PLC control system is well suited for neon switchadjustments,resolving time and direction of scintillation,and how fast,reliable,andconvenient operation.In the paper,we first proposed a design for the neon ad screen.Next,soft hardware design of neon ad screen control system was completed.Thehardware portion includes the I /O layout and the PLC option,and the softwareportion contains flow charts and program trapezoidal diagrams.Finally we test thecontrol system designed through the system and meet the design requirements.Keywords:neon advertising screen;PLC;control system
