It realizes one-to-one monitoring and management of street lamps. Installation and construction is simple and quick, without damaging the status quo of the equipment and not damaging the environment. It does not affect the normal life and work order, no need to set up special lines, easy to install and modify, ready to use, no need to debug, easy to use, greatly reducing energy saving and construction costs.
First, the status quo and development trend
a) The status quo of urban lighting: The traditional lighting management system based on clock control and manual control has the following problems:
1, a large number of urban lighting: the use of traditional control methods, difficult to manage.
2, the coverage of the city lighting system is wide: the operation of the system needs to send people and vehicles to patrol every night, especially the damaged street lights can not be found in time, which affects the effect and uniformity of urban lighting, increasing maintenance personnel and maintenance costs .
3. Adopt manual management mode: It is necessary to adjust the clock controller to the site, which is difficult to work. Especially when it is necessary to complete some urgent special tasks, it is even more difficult to respond quickly to meet the requirements of the leaders and cause negative impacts.
4, can not be found in time for various faults: there are security risks. It is also impossible to count data such as voltage, current, power, and power usage of the entire system.
5. Due to the inability to adjust the time of switching lights in time, the waste of electricity is serious.
6. With the increasing improvement of urban street lighting technology: higher requirements for the diversification and scalability of this technology. For example, in addition to the monitoring of cables, wires, street lamps, and light bulbs, such as the statistics of electricity consumption and the automatic drainage of roads, the unified management of buildings, landscapes, advertisements, and green lighting, and the intelligent irrigation of green belts.
7. Due to the backwardness of the lamp control system: Up to now, there is no control system in the country, which can implement point-to-point control of street lamps, resulting in a large amount of waste of cables and wires, which destroys the environment and increases construction costs, and also increases maintenance. Difficulty and cost.
b) Trends in urban lighting development :
With the continuous development of economic and social civilization, street lamps are no longer limited to street lighting, but through the perfect combination of science and art, to create a good lighting effect, and establish the city's brand image. Therefore, modern society will have higher and higher requirements for the management and maintenance of street lamps. In order to comply with the development of the times, the development trend of urban lighting management will tend to:
1. Unified switch and centralized control: centralized monitoring and unified management, so that the entire city lighting can achieve “one knife†control.
2, real-time monitoring: real-time monitoring of the fault of the electric (road) street light (bulb), at any place, under any circumstances, any time, the operator and the person in charge can find the location and lights of the line fault in time Rod position, as long as the maintenance personnel are notified, the fault can be eliminated in time.
3. Flexible setting: With the seasonal changes and special circumstances, it is necessary to flexibly adjust the lights of the whole city. It can turn on and off the lights of any street lamp, part or all of the street lights at any time. All you have to do is just a click on the keyboard.
4. Query and statistical report: realize the functions of querying, retrieving, monitoring, counting, maintaining and updating the lighting data at any time. For each day, the status of the equipment and the alarm information are recorded and the report data is formed forever.
5. Reasonable energy saving: According to the actual needs of work and life, the area, road section, time period and any street lamp can be set in advance for time switch, automatic control, monitoring, and real-time switch control. According to the needs of different seasons and weather changes, set the time on the computer, the system can automatically complete the switch, not only save manpower, but also eliminate the contradictions and mistakes caused by human factors, more effective energy saving, better solution Street lights, landscape lights all night long and the contradiction between lighting energy saving and safe lighting.
Now only need to set the working time on the microcomputer, the street light will automatically become the interval light pole or the same pole bright half lighting (all without additional wiring and construction), but also to protect the key parts (area) bright The safe location (area) is not bright or light, the place where the activity is needed is bright, the place where there is no activity and no need is not bright or less bright, only this one saves 25%--52%, which can save energy. purpose.
It is precisely because of the current management problems of urban lighting, and the future development trend, it is very necessary to build an advanced urban lighting monitoring system to reduce the difficulty of work, improve work efficiency, save energy, and enhance the city's brand image. The KSDC-A urban carrier street lamp energy-saving monitoring and management system independently researched and developed by the company has completed the remote automatic communication and real-time copying of the urban carrier energy-saving street lamp intelligent control system, industrial and civil (water, electricity, gas, heat) tables at home and abroad. Reading, metering, monitoring, control, charging and management are the new generation of products that are still being developed around the world!
Second, the system constitutes
The urban carrier street lamp energy-saving monitoring and management system mainly consists of a monitoring center, a concentrator, a carrier street lamp terminal controller, a carrier set metering terminal, and software. The system can be composed of different scales and different requirements according to different city conditions. (See the composition on the next page)
a) Monitoring Center: It is mainly responsible for the monitoring and management of the city's lights, including the instructions for issuing the switch lights and receiving the data of the terminal lights of the carrier lights. It can realize the control methods of annual timing control, daily timing control, pre-planning timing control, forced control, light control and time control for single lamp, whole and partition. In addition to fixed monitoring center, it can also realize mobile control center control.
2) Concentrator: A concentrator shall be installed under each transformer station area, and the concentrator may be installed anywhere with three-phase electricity. The concentrator can control the carrier to download the street lamp terminal controller and the carrier (water, electricity, gas, heat) table and other carrier terminators.
The concentrator and all the carrier street lamp terminal controllers and carrier function table and carrier function terminator in the field form a secondary network, which can directly use the low-voltage power line carrier communication, without the need to lay a special line, the construction is simple and quick, and it is easy to newly install and old engineering. Ready to use, no need to debug, no maintenance, easy to use, low cost.
The computer of the management control center and the concentrator of the site form a first-level network, in which a telephone line, a radio, a dedicated line, an optical fiber or a broadband network can be selected for communication.
3) Real-time control (carrier street light terminal controller): The carrier lighting terminal controller is a self-designed and researched successful power equipment management product in accordance with the State and the Ministry of Electric Power and relevant international standards. (There is no such product at home and abroad) It is difficult to manage the long-term energy conservation, control and detection of electrical equipment, such as large oil fields and industrial equipment.
IV) Carrier Set Metering Terminal: The carrier meter is a new generation of power carrier set-end terminal products that our company independently designs, researches and develops under the strict ISO9002 standard control conditions according to the State and the Ministry of Power and relevant international standards. (The product fully realizes the requirement of the Ministry of Construction to propose the "integrated design of the carrier control system must be integrated with the metering system"). It integrates energy metering, data acquisition, error-free transmission, data permanent storage, time-sharing billing, reminder of electricity charges, and continuity. Control and other functions in one. The system products: high efficiency, energy saving, stable operation, safe and reliable, flexible management, convenient operation, real-time accurate, 100% copying success rate, data accuracy rate of 100%, control rate of 100%.
5) Carrier lighting remote energy-saving monitoring software: The system has the function of monitoring the fault of the electric line (road) street light. The operator can easily find the location and location of the line fault. As long as the maintenance personnel are notified, the fault can be eliminated in time. Such as: street lamp repair, used to drive all street lights during the day, in order to find faults one by one, obviously waste. Now, as long as you look at the microcomputer and write down the fault light pole number, you can go straight to the light pole to overhaul, the target is clear, and the work efficiency is greatly improved.
The installation of the network system does not damage the current situation of the facility and the surrounding environment, does not affect the normal work and life order, the construction is simple and the construction period is short. The monitoring center can manually or automatically use the electricity consumption, the switch light schedule, the lighting rate, Parameters such as switch status are collected. All historical data can be queried and printed at any time as needed, and various daily, monthly and annual reports are automatically generated.
6) System configuration: It can realize system related functions such as user operation authority configuration, data backup, system parameter setting and so on.
VII) The system functions can be arbitrarily extended according to needs: such as unified management of lighting for buildings, landscapes, advertisements, greening, automatic pumping of roads and monitoring of urban air quality, automatic spraying of roads, etc.
Third, the system features
a) Install the network system: no additional wiring is required, and the cost is low. It is easy to install new street lamps and old street lamps. It does not damage the current situation of the facilities and the surrounding environment. It does not affect the normal work and life order. The construction is simple and short, the construction period is short, and the cables and wires can be saved to the maximum extent. The function extension space is large, which is advocated today. A good scientific and intelligent management device for a conservation-oriented society.
b) There is very flexible scalability: if you need to add control units or projects under the same transformer, you only need to increase the carrier function control terminal.
3) Automatic on/off operation can be carried out every day: 8 kinds of timers can guarantee the working day and the power will be automatically turned off and off at different times on holidays. The electrical equipment can be partitioned and managed by line.
4) Through the setting of microcomputer and concentrator: prevent unauthorized persons from operating and ensure that the circuit breaker is safe and reliable. According to the power consumption situation, it can be judged that the unattended power equipment operates. All operating parameters (automatic on/off time, area division) can be set at any time in the management terminal, enabled at any time, and easy to manage.
5) Saving power and maintenance costs: In the microcomputer control software, the area, the road segment, the time period, the next one, and the second interval are used to automatically control the time switch, and the switch control can also be performed in real time. According to the needs of different seasons and weather changes, the system can be self-finished by setting the time in advance on the microcomputer. It not only saves manpower, but also eliminates the contradictions and mistakes caused by human factors, and effectively saves energy.
