Abstract

The invention discloses a wireless packet remote monitoring system for a city road light-emitting diode (LED) lamp. The system mainly comprises a monitoring center, a remote monitoring terminal, remote terminal equipment and a street lamp; the monitoring center communicates with the remote monitoring terminal through a transmission network; and the remote monitoring terminal is in communication connection with multiple pieces of remote terminal equipment arranged on the street lamp. Because micro control unit (MCU) and system on chip (SOC) technologies are integrated to form an intelligent module with an adaptive control algorithm in the remote terminal equipment, and a series of LED lamp constant current modules driving different voltages and powers can be formed through electrically erasable programmable read only memory (EEPROM) digital write-in, the invention has the advantages that: information is exchanged timely and accurately, intelligent monitoring is realized and scheduling and management degree is high.

Description

City paths of LEDs lamp packet radio long distance control system

Technical field

The present invention relates to a kind of supervisory system, particularly relate to a kind of city paths of LEDs lamp packet radio long distance control system.

Background technology

Street lamp illumination system is the requisite public utility in city, and it has directly reacted its construction level and the cityscape in a city.The streetlight monitoring system of China develops to some extent in recent years, but also is in developing stage, starts late in light regulation and control, research aspect energy-conservation.The utilization rate of light regulation and control in Gary road lamp management system accounts for 70%, and Europe accounts for 40%～50%, and the Asia accounts for 10%～15%, accounts for 15%～20% in Japan and Korea S., and China is less than 1%., compared with developed countries, China's city street lamp management system is bigger in the energy-conservation gap of light regulation and control.

The open and close control of present domestic most city street lamps is still by every transformer (panel box) decentralised control, and have a lot of problems: (1) system complex is difficult to unified management; (2) the lighting system broad covered area is difficult in maintenance, safeguards the strength wretched insufficiency; (3) the switch control efficiency is low, the electricity consumption serious waste phenomenon; (4) there is potential safety hazard, can't grasps the street lamp running status fast, no safety guarantee.

Road lamp management system " manual patrol ", real-time are poor in order to overcome, the handling failure inefficiency, expend shortcomings such as lot of manpower and material resources, and China begins monitoring technique is applied to the city illumination field from the nineties.But the streetlight monitoring system of China all adopts the single communication mode at present, adopt wireless data transmission radio station private network communication, GSM/GPRS communication or adopt wired solution to communicate, GPRS takies communication network, when large-scale festivals or holidays, telephone traffic was bigger, be easy to cause congestion information, make streetlight monitoring be obstructed.So, be necessary to study the wireless automatic network-building supervisory system of novel ad hoc mode, with real-time control with detect every LED lamp source, if the data that note abnormalities are then reported to the police and located.Thereby realize Intellectualized monitoring, scheduling and the management of real-time information interaction between street lamp and the Surveillance center.

Summary of the invention

The object of the present invention is to provide that a kind of information is handed in time, city paths of LEDs lamp packet radio long distance control system accurately.

For achieving the above object, technical solution of the present invention is:

The present invention is a kind of city paths of LEDs lamp packet radio long distance control system, and it mainly is made up of Surveillance center, remote monitoring terminal, RTU (remote terminal unit) and street lamp; Employing RS232 serial communication of described Surveillance center or multiple networking mode communicate with remote monitoring terminal and are connected, realize exchanges data, remote monitoring terminal adopts AdHoc dynamic group net technology to communicate with a plurality of RTU (remote terminal unit) that are installed on the street lamp to be connected, remote monitoring terminal is responsible for RTU (remote terminal unit) monitoring and management, accept the operational order of Surveillance center and return the single lamp state and the analog quantity information of the terminal of having jurisdiction over collection.

Described RTU (remote terminal unit) comprises microprocessor, data acquisition module, executor module and RS232 serial communication modular; Described data acquisition module, executor module, RS232 serial communication modular all are connected with the signal output or the input port of microprocessor.

After adopting such scheme, the present invention has following characteristics:

1) traditional led drive circuit is transformed, to overcome the infringement of too high defective of direct current constant-current circuit energy consumption and peak voltage to the LED device.

2) RTU (remote terminal unit) adopts MCU and SOC technology to be integrated into the intellectualized module with adaptive control algorithm, writes by the EEPROM numeral, can form the series LED lamps constant flow module that drives different voltages and power.

3) adopt high-performance section bar pipeline exhausting formula heat dissipation technology to improve radiating efficiency and LED optical efficiency.

4) adopt the wireless automatic network-building technology of AdHoc, set up LED street lamp illumination system remote monitoring platform, digital management level in LED urban lighting system is provided, realize remote energy-saving control, further reduce its energy consumption.

So the present invention has the information friendship in time, accurately, Intellectualized monitoring, scheduling and the high advantage of management degree.

The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
