1. Significance of street lamp monitoring system:
The urban street lamp lighting system is an important symbol of urban modernization. The street lamp monitoring system is an indispensable means of advanced scientific management methods and measurement and control of street lighting, and has a qualitative leap compared to the original clock-controlled timing switch management. On the information highway leading to the 21st century, the street light monitoring system is of great significance in promoting the modernization of city construction, informationization, energy saving, beautifying the city, and convenient management.
2. System function
1) Remote control: The management center computer automatically controls the monitoring group to turn on/off the group lights according to the schedule set by the season, temporarily change the on/off, and additionally uses the light control time control combined with on/off. Realize the monitoring of night lights, midnight lights, landscape lights, and high-rise floodlights. When the host computer is not online or due to an unexpected situation, the monitoring terminal of each monitoring point can automatically run according to the last set time, ensuring the system. Stable and reliable.
2) Telemetry: automatic inspection or random detection of voltage, current, power factor, active power and frequency and other operating parameters of each monitoring point, automatic calculation, statistics, query each street lamp control lighting lamp rate.
3) Remote communication: access to on/off status of each terminal, door opening switch, flooding, smoke alarm, cable anti-theft alarm, fault and alarm, etc. to ensure the system operates normally and normally.
4) Remote adjustment: Reasonable pressure regulation, energy saving, and can extend the use of lamps
5) Remote Video: Adding video surveillance functions on some important road sections allows more intuitive monitoring of the site
6) Satellite Timing: Accurately Calibrating the System Clock
7) Electronic map: integrated GIS electronic map information platform, vectorized map zooming, panning, target locking, quick search and other operations
8) Online version management software: Internet remote login function, support remote query, remote management and remote maintenance. The support center monitors hierarchical management and multiple sub-control centers can be set up
3. Comparison of system advantages:
China Mobile's GPRS network has a wide network coverage (100% urban coverage), signal stability, real-time performance, strong scalability, good anti-interference, easy installation, and low cost advantages, GPRS network Provides a reliable wireless transmission platform for street light monitoring systems. The entire system saves 10-20%. There is no need for a traditional patrol car to check back and forth, saving manpower and material resources.
Adopting the traditional data transmission radio communication mode not only requires the construction of a transmission tower, but also has a very limited coverage. It has a fixed position and cannot be moved, and the investment cost is high. The wider the coverage, the higher the construction cost. With the continuous development of urban construction, the higher the number of buildings to be built up, will hinder the communication between the tower and the terminal. Moreover, due to the effects of bad weather, other disturbances, and the difficulties of inspection, there are many drawbacks in the street lamp monitoring system.
