Design A Tunnel Lighting Control System Based On Zigbee Technology

With the development of the Internet,the era of the Internet of Things has arrived.The application of wireless control technology has spread to every comer of our lives.The awareness of energy conservation and environmental protection is also constantly strengthening.Tunnel lighting is a major link in tunnel construction.A good tunnel lighting system can not only ensure the normal passage of tunnel vehicles,reduce the occurrence of traffic accidents,but also automatically close the lamp when there is no vehicle.Turn off the lamp to reduce energy waste.It saves the cost of tunnel operations.Therefore,it is very necessary to design a tunnel lighting intelligent control system.According to the characteristics of tunnel lighting and the actual feasibility,the research status of tunnel lighting at home and abroad is investigated by reading related literatures,and different technologies are compared and analyzed.Based on the characteristics of Zigbee convenient networking,a Zigbee Lighting control system about tunnels is designed.From the analysis and comparison of various popular lamps on the market,it is more suitable to compare the LED light as the light source of tunnel illumination.The structure of the LED lamp was analyzed.Improve the lighting efficiency of LED lamps.The main workflow of the system is to use the sensor to collect the corresponding data,and use the wireless transmission method to transmit the collected data to the coordinator node,The data is displayed on the interface of the host computer.People can know the tunnel lighting situation in real time,and can send corresponding control command.The lamp is controlled by the wireless network according to the actual situation.The system can be mainly divided into two parts:the hardware part of the wireless sensor node and the software part and the design of the host computer.The core chip used in the hardware part is CC2530.With this chip,a fully functional wireless network can be built with minimal cost.The design of the hardware mainly includes:the selection of the sensor,the design of the serial interface,and the selection of the controller.The software function program is designed mainly in the IAR software platform,and mainly includes programming for communication with the host and programming for receiving and processing terminal sensor data.The host computer is designed using the Qt platform.The monitoring interface has the function of displaying the status of the luminaire in real time,switching the control mode,and freely monitoring the frequency adjustment function.When the tunnel luminaire fails,it can alarm in time to facilitate the daily maintenance and repair of the staff.The safety of tunnel lighting is guaranteed.Finally,the whole system was tested.Through the test,the system can not only realized the intelligent control of the tunnel lighting,but also reduced the workload of the staff and reduced the operating pressure of the tunnel by using the fault detection function.
