Urban Roadside Advertising Intelligent Controller

Civic roadside advertisement brand is located sides of road in the city, striking, economical and practical, beautifying civic environment. So, it is in good graces of many advertisement corporations and users in recent years.Without controlling facilities for a special purpose now, current lamp-box advertising brand combines and makes use of common ballast of fluorescent lamp, consequently it frequently .goes wrong, and it has many disadvantages, such as simplistic control mode, shorter lamp-life, great EMI interfere and poor effect of energy conservation.With green illumination and engineering, of energy conservation putting into practice in our country, it is much higher to request of EMI and energy conservation on electronic equipments. Therefore, it is inevitable trend and extremely imperative to develop a kind of lamp-box controller with little EMI interfere, efficient, multi-function, durable and economic.The new developed and researched advertising lamp-box controller is provided with the centralized control mode, the centralized supply power way and the reserve lights mode. By this means, lamp-box advertisement brand with multi-function, little EMI interfere, efficient, durable and economic can be designed.Firstly, the whole idea of scheming design is presented, and it is elaborated in detail to every component part of main machine and its fundamental working tenets.Secondly, it is made detailed introduce to every component part of branch machine and its fundamental working tenets, which emphatically expound the circuit project of high-frequency main power and the reserve lights control way, and so on.Finally, communication between main machine and branch machine is discussed in detail. It is analyzed to power line carrier technology and DTMF technology. And working way and communication agreement of DTMF is illuminated. In conclusion part, further research-orientation in future is elaborated.
