Zigbee street lamp control system
With the development of social economy and technology, urban street lamp control system has gradually changed from time or illumination control to more energy saving single lamp remote intelligent control. At the same time, the intelligent and networked lighting control system is also the development direction and inevitable trend of the future city street lamp, home lighting control. This paper introduces an intelligent remote street lamp control system which combines zigBee AD hoc network module with GPRS DTU, street lamp control terminal, acoustoptic and infrared sensor.
The system topology is shown as follows:
1. Control terminal: mobile phone or PC is used as the control terminal to obtain the state of remote street lamps through the network or SMS or manually control the state of remote street lamps;
Two, data server:
1. Obtain and store the information status of remote street lamps in real time, and automatically send abnormal status to the mobile phone of the manager by SMS;
2. Real-time feedback of street lamp information to the control terminal;
3. Send the command sent by the control terminal to the remote street lamp;
Data transmission terminal: ZigBee routing +GPRS DTU can realize the zigBee street lamp network data sent to the server through GPRS DTU; And to obtain the instructions issued by the server and sent to the specified single lamp control node;
Four, single lamp control node:
Single lamp control node uses ZigBee as data transmission coordination channel to realize real-time dynamic control of street lamps. At the same time, a feed-like sensor is used to obtain the external state information dynamically.
System functions:
· Single lamp can be remotely monitored and luminance can be adjusted;
· The lamp can be switched on and off automatically according to the ambient light, and the luminance of lamps can be adjusted to ensure the use needs;
· According to whether there are pedestrians/vehicles on the road to achieve brightness gradient, more energy saving;
· When a street lamp is damaged, it can alarm and report the specific location of the faulty lamp;
· Data such as electricity consumption, lighting rate and power consumption of street lamps can be provided, and historical records can be queried for clearer and more convenient management;
