Lighting control system is a complex system engineering, and there are many means in its control such as hand, electric, clock control, centralized circuit control, GPRS remote control, etc. In recent years, with wide application of streetlamps and landscape lights, a large amount of power is used up, therefore, the energy-saving technology has become one of the hot research project.At this stage, the main easons of landscape lamp lighting energy consumption reflect that monitoring of control systems is not focused, and real-time monitoring ability is insufficient; Controller routing algorithm network performance is low; Solar street lamps system has short life; photovoltaic control systems are ineffective. Aimming at the above problems, on the basis of the previous work, this paper has made the following innovative achievements:1. Based on Zigbee and GPRS, the urban lighting single lamp light tone of energy-saving technology complete solutions is put forward. The Zigbee and GPRS for data transmission, realize the single lamp intelligent remote real-time monitor. Based on active PFC technology, comprehensive energy consumption is reduced by40%or more, remarkable energy saving.2. Putting forward SINGLE-NODE routing algorithm, based on a combination of ant colony algorithm and routing algorithm, so that the performance of the network get the best play. And the corresponding mathematical model was established, and in theory the validity of the algorithm is verified. The algorithm has been used in the design of the TDFY3400street light controller. In the River East Road of Taiyuan city, landscape lightings are widely used.3. Put forward an improved algorithm of reserved frame-slotted Aloha, the RFSA algorithm reserves slot for serial to be sent by sending a short random number in the micro slot of time frame header. Using special encoding, the reader can determine data reading status from the received random number to reserve corresponding slot.4. A kind of hop-to-hop controlled hierarchical multicast congestion control mechanism combining RED and HTH was presented. With this mechanism, each router determines its congestion status based on current network state. If congestion occurs, it discards with certain probability and report congestion status to upstream router. After router received congestion state from other routers, it will take appropriate measures to increase or decrease transmission rate to some downstream router. At the same time, packet discard number of each link was considered in congestion control to ensure fairness.5. Put forward a kind of the urban street lamp lighting control scheme based on super capacitor photovoltaic technology. Through the super capacitor in connection to the front of the photovoltaic system, insufficient in the illumination, take super capacitors for battery charging control strategy, and reduce the illumination change to charge the condition the influence, to ensure the photovoltaic cells to obtain the most power tracing, storage battery charging and discharging the reasonable demands are met. Finally, the Simulink/Matlab simulation model is established to prove validity of the method. The results show that the method can solve the shortage of the traditional methods, prolong the life of solar street lamps system, and so improve the efficiency.6. Put forward an improved modeling method of RBF neural network photovoltaic battery. With sunshine, temperature and load voltage as input values of RBF neural network model, output power of photovoltaic cells as output values, by adopting RBF neural network, which possess the approximate complex nonlinear function, the model of photovoltaic cells is built, and by using particle swarm algorithm, the RBF neural network is optimized, finally, the dynamic response model of the photovoltaic cells is built.
