The Street Lamp Controlling System

This paper has designed software and hardware of the street lamp controlling system. In order to advance the real time and veracity of the sample the system used dual 12 bit ADS7864 converter. The ADS7864 is a high speed,low power,6 channel,sample/hold analog-to-digital converter. The system not only used the keyboard display integrate circuit of HD7279A in order to predigest circuit and decrease disturb that of unsure but also increased the watch-dog circuit on the safe side work. It cite CDT protocol in the correspondence. It not only organize and send telesignal data,telemetering data etc to main station but also receive the command of main station to implement telecontrol command according to the protocol.The system provides local display of telemetering data,telesignal data,baud rate,local address and telecontrol implement command etc. It was proved that the system can run safe and credibility,promotes efficiency of the city street lamp controlling system,prolong the street lamp using time and save a great deal of money,...
