In the hot download of the "Green Lighting Technology Special Issue" in May, how can you miss it!
With the increasing emphasis on urban lighting engineering, the workload of street lighting management, monitoring, control and maintenance is increasing and the contradiction between limited human and material resources is becoming increasingly prominent. Therefore, wireless remote monitoring of street lamps will become a future development trend.
The intelligent street lamp control system independently developed by Shanghai Shunzhou Electronic Technology Co., Ltd. is specially developed for the specific characteristics of street lamp management and strictly in accordance with the national standard "Electrical Equipment Safety Design Manual" and other standards. It can increase the processing and communication functions on the basis of monitoring the various equipments and environments such as the existing power distribution equipment and control equipment of the street lamp system, effectively reducing the construction cost of the system. The intelligent street lamp control system uses advanced communication technology and computer network technology to match the actual situation of street lamp management, and has many innovations in terms of its practicability, reliability, technological advancement and economy.
The urban intelligent lighting system has the following characteristics:
1. Each set of street lamps has a separate on-off function, which means “single lamp single control†can be realized, and the voltage, current and power factor of each lamp can be monitored.
2. The street lamp management system software can realize the functions of different modes such as “one bright one†or “two bright ones†according to the actual needs of the user and according to the brightness requirements of different time periods at night;
3, with latitude and longitude clock control function, according to the local latitude and longitude, according to seasonal changes and daily sunrise, sunset time, automatically adjust the switch light time. The user does not have to enter a specific switching time, the control system can automatically achieve the on-off function.
4. In addition to the function of automatic switching light in the morning and evening, the street lamp control system can use the strategy control to realize the automatic switching function at other times during the night;
5. The communication from the collector to the terminal control platform of each loop in the street light control system is a wired network or a wireless transmission mode;
6. Each loop in the streetlight control system has a metering function. The data of the remote meter is realized through RS485 communication, wireless network, etc. The street lamp control system needs to finally transmit the power consumption of each loop to the corresponding energy supervision platform control. Room, can automatically generate electricity consumption daily report, monthly report and annual report, and dock with the energy supervision platform.
In summary, the ZigBee Light Link (ZLL) lighting control standard can be used to complete the system. ZLL is specifically designed for lighting applications. Thanks to this optimized design, ZLL products can easily achieve color settings, dimming levels and brightness settings, storage scene modes and automatic light control for maximum convenience and maximum energy efficiency. . System functions can be as simple as turning on/off the lights, or as complex as a full-featured home lighting solution, bringing light to the city while also achieving energy savings.
