With the continuous development of smart city, energy saving, multi-aspect control, cost saving, intelligent control and other aspects are constantly proposed, which promote the innovation of various industries and accelerate the upgrading of products. Smart light pole also comes into being based on this background. Intelligent lamppost is an important part of the construction of smart city, and its appearance is inseparable from the intelligent hardware of the light control core - single light controller.
Single light controller, in a word, can realize the control of each street lamp controller, mainly used in smart light pole, multi-function pole or customer specified occasions. The following take the single light controller of Hangzhou Sanqian Smart City Technology Co., Ltd. as an example, to talk about the functional characteristics of the single light controller.
1. What is the single light controller?
The single lamp controller of Hangzhou Sanqian Smart City Technology Co., Ltd. is specially designed for single street lamp control terminal, the basic task is to realize the single lamp longitude and latitude control, timing control, manual control and other control modes; Intelligent switching control mode; Intelligent adjustment of street lights bright, switch and other functions, to achieve on-demand lighting, in order to achieve the urban road lighting automatic control, fine management, energy saving and emission reduction purposes.
2. Working principle of single lamp controller
The working principle of the single light controller of Hangzhou Sanqian Smart City Technology Co., Ltd. is to use Cat1/ broadband carrier communication technology for data transmission. The collected data of LED street lamps, lamp turning off, voltage, current and power factor are submitted to the monitoring center through the network, and the control instructions from the monitoring center are received to complete the switching and brightness adjustment of lighting facilities.
3, single light controller system composition
The single light controller transmits data based on Cat1/ broadband carrier communication technology and is directly connected to the server to realize the management and control of single light by background software. The single light controller without communication module cannot be used alone, but must be used with the intelligent centralized controller and the intelligent light pole management platform system:
Single-light controller: Controls the host to receive instructions from the monitoring center, turns on and off lights and adjusts voltage at the single-light level, and proactively collects single-light fault information and reports it.
Centralized controller: is responsible for controlling the operation of the network, issuing the command of the monitoring center to the single light controller, and feeding the controller and line information back to the monitoring center.
Smart light pole management platform: responsible for issuing various instructions, turning on and off the light and responding to special emergencies.
4, the characteristics of single light controller
1. Energy consumption saving: According to the field needs, switching and dimming strategies can be developed according to season, time period and illumination, which can greatly save energy consumption and extend the service time of lamps.
2. Fast and convenient installation: using wireless 4G Cat1 technology, no need to lay communication lines, remote single light monitoring, remote timing inspection, automatic fault alarm can be realized by using the original power line.
3. Reduce operation and maintenance costs: intelligent control, equipment self-inspection, reduce manpower, material resources, operation and maintenance expenses, help enterprises effectively reduce the operation of the north of the city, improve management efficiency.
5. Function characteristics of single light controller
a. Data acquisition: real-time monitoring of street lamp voltage, current, power, electric energy and light duration and summary, real-time identification of electric energy data;
b. Intelligent control: it can realize the timing function control, latitude and longitude control, timing switch, illumination control, weekly working mode, switch control and delay start of street lamp. It can implement both the concentrator controller strategy and the single lamp controller's own control strategy.
c. Fault detection: intelligent algorithm is adopted to detect the working state of street lamps and abnormal alarm of street lamps, which is convenient for users to monitor and maintain lamps. It supports leakage detection and lamp pole tilt detection, and supports active fault reporting function.
d. Fault alarm: The controller has built-in alarm functions for ultra-low voltage, current, and ultra-high power faults, as well as protection device fault alarms.
e. Support remote equipment maintenance: it can check the working status of the equipment remotely, automatically detect the abnormal situation of trip, leakage, air switch, etc., assist maintenance personnel to find out the cause of the fault, and greatly save the maintenance cost.
f. Built-in energy saving policy function: Supports periodic turning on and off of the local latitude and longitude and dimming policy. Supports automatic dimming according to the preset light when the Internet is disconnected or offline, and automatically runs the built-in energy saving policy of a single lamp.
g. One-click configuration: Supports one-click query and one-click control, improving deployment, operation and maintenance efficiency.
In addition, according to the project requirements, Hangzhou Sanqian Smart City Technology Co., Ltd. can provide customized single light controller options. At present, there are NB-iot, 4G, Cat1, Zigbee, LoRa, PLC and other options. Welcome to consult.
