In the future, the market capacity of the industry will reach 400 billion yuan, with huge development space. Industry analysts believe that contract energy management will become a lever to incite the entire energy-saving market.
Typical, incarnation
Xiamen Yuangu Information Technology Co., Ltd. and the owner agreed on the energy-saving target of the project in the form of contract, and the company provided energy-saving equipment and services for the owner, and the owner shared the energy-saving benefits with the company. After the expiration of the contract, the energy-saving equipment shall be owned by the owner.
Yuangu will make full use of urban lighting energy-saving comprehensive solutions and building energy-saving solutions, and implement contract energy management projects with the owners in the field of building and lighting energy-saving.
Contract energy project management process:
Energy-saving benefit sharing mode of contract energy project: the function of GPRS wireless remote monitoring system for street lamps and landscape lamps
(1) Remote control function: it supports automatic control of switch lights, latitude and longitude control switch lights and instant manual switch lights when inputting schedules, and also supports remote control by SMS.
(2) Telemetry function: The central control room can conduct automatic inspection according to the set time period, or randomly telemeter the running status of street lamps and landscape lamps in various sections of the city, and inquire about the incoming voltage, three-phase current, power consumption, contactor switch status, ambient temperature, short circuit and open circuit of each distribution control cabinet; Through the analysis of these data, useful data such as the line status, lighting rate and fault cause of street lamps and landscape lamps are obtained. In addition, the operator can also manually patrol and select the operation of each monitoring terminal at any time.
(3) Alarm function: When the monitoring equipment terminal actively gives an alarm or the monitoring center finds an alarm during telemetry, the central control room can automatically report the fault by voice or text, and support SMS alarm. The alarm contents include: lighting during the day, turning off the lights at night, and abnormal opening of the power distribution cabinet door.
(4) Remote meter reading: The monitoring terminals of street lamps and landscape lamps can be connected with smart meters with RS485 communication interface, and the electricity consumption of each street lamp and landscape lamp line can be uploaded to the monitoring center, which solves many problems such as high cost and inconvenient control brought by manual meter reading in the past.
(5) Data query, data statistics and printing functions
A) Inquire the current, voltage, illumination rate and operation data of electrical equipment of each monitoring point at any time, and print and archive them;
B) Inquire the historical data of each monitoring point for one month, one day or a period of time;
C) Inquiring the switching time and lighting time of each monitoring point;
D) Inquire about the settings of street lights, landscape lights, night lights and night lights at each monitoring point;
E) the basic settings of the query system;
(6) User management function: The system software has the function of user rights management. According to the actual needs, set up multiple users with different permissions. After users with different permissions log in to the system, they can only perform various operations permitted by their permissions in the system.
raise
(1) GIS Geographic Information System: Build a real-time and visual geographic information service platform. Based on geographic information, the existing system is integrated, and all kinds of data such as street lamps, cable geographic location, loop layout and real-time dynamic information of monitoring points are collected for centralized management, analysis and query, so as to provide real-time visual information for managers.
(2) Large-screen projection: The system can display the monitoring picture on the large-screen projection, and intuitively display the information and orientation of the street lamp and landscape lamp monitoring system. The operator can conveniently display the monitoring information of various street lamps and landscape lamps through the operation of the microcomputer keyboard.
(3) The mobile phone remote control switch light is on.
(4) Time synchronization of satellite clock or network clock server. 1, system composition
YG-FD-T 1 Street lamp cable anti-theft system is mainly composed of anti-theft front end and anti-theft end. The anti-theft front end is mainly composed of switching power supply, power supply control panel, relay and other high-voltage accessories. Each front end can have multiple anti-theft ends, and the front end is installed in the street lamp control box. The anti-theft terminal is mainly composed of intelligent voltage detection module and intelligent short message sending module. The anti-theft terminal is installed on the last lamp post at the end of the cable.
2. The working principle of the system
The system structure is shown in the figure. When the street lamp is turned off, the anti-theft front-end equipment provides 48V weak DC power to the cable. When the street lamp is turned on, the front-end equipment turns off the 48V DC power supply, and the cable is powered by the 220V AC power supply. When the street lamp cable is cut off artificially and the anti-theft terminal cannot detect one of these two voltages, it will immediately output an alarm signal to the administrator's mobile phone.
3. Main technical indicators of street lamp cable anti-theft system
(1) When the line is disconnected and sent to the designated mobile phone, the delay of receiving SMS alarm information by the mobile phone (under normal GSM network) is less than 30 seconds;
(2) Monitor and give an alarm for the open phase and disconnection of urban street lamp power supply lines (AC380V/220V);
(3) Support automatic identification of mobile and Unicom GSM network SIM cards;
(4) Support SMS to set three alarm numbers;
(5) Support SMS to set alarm content;
(6) Support to modify the mobile phone number of the short message receiver;
4. System characteristics
The adapter controlled by (1) microprocessor makes the system run with high reliability and the false alarm is close to zero.
(2) The system automatically adapts to the change of site conditions and changes according to the change of regional conditions, which can effectively detect the abnormal situation of lines and even distinguish between lighting faults and cable anomalies;
(3) The installation mode is simple and easy to install in the existing street lamp and transformer system;
(4) High-level detection ability, able to detect theft, determine alarm and give quick feedback to make security personnel respond;
(5) Low maintenance cost and convenient system operation. Not affected by sunshine, rain, fog, snow and other climates;
(6) Waterproof design, which can be used in harsh environment;
