Detailed Description
The following description is presented to enable one of ordinary skill in the art to make and use the invention. The preferred embodiments in the following description are by way of example only and other obvious variations will occur to those skilled in the art.
In order to better understand the pedestrian traffic violation identification method in the invention, firstly, nouns related to the embodiment of the invention are explained.
Positioning
The user part of the GPS consists of a GPS receiver, data processing software and corresponding user equipment such as a computer meteorological instrument and the like. The GPS satellite navigation system is used for receiving signals sent by the GPS satellites and performing navigation, positioning and other works by using the signals. These three parts together form a complete GPS system.
Abbreviations for geographic information science. The system is a technical system for collecting, storing, managing, operating, analyzing, displaying and describing the related geographic distribution data in the whole or partial earth surface (including atmosphere) space under the support of a computer hard and software system.
And positioning each street lamp and longitude and latitude of each device through a GPS positioning technology, and drawing the street lamps and the longitude and latitude of each device on a GIS map correspondingly.
Communication system
The communication technology between the intelligent street lamp control system and the street lamp control cabinet adopts a 4G communication technology, a 4G internet of things card is inserted into an urban intelligent lighting control terminal in the street lamp control cabinet, and data information is uploaded to the intelligent street lamp control system, telemetering, remote signaling and remote control data are sent, alarm data are sent and the like through a 4G mobile network; the intelligent street lamp control system issues an instruction to the street lamp control cabinet through the mobile internet, the 4G card of the intelligent lighting terminal of the control cabinet receives instruction information, and the next action is correspondingly executed according to the instruction.
Because the coverage range of the network signals of the operators 2G/3G/4G is wide, the network signals can be practically used
The region of 2G/3G/4G service is also very wide. Second, the terminal can roam freely in the signal coverage, the developer does not need to develop any other communication equipment (which is responsible by the operator), and the use of the terminal is convenient. The cost of mobile communication terminals has been greatly reduced due to their popularity. In the communication mode, optical fiber communication is adopted conventionally, and although the optical fiber transmission quality is higher, the construction cost is higher because the optical fiber is laid by excavating movable soil. Therefore, the design considers that 4G communication is adopted as a communication mode between the control system and the street lamp control cabinet.
Under the current time node, the 4G communication technology is mature and widely applied. Before 5G has not been truly popular, a 4G network is represented by the highest network speed of the current social communication network, and a 4G internet of things card implemented through the 4G network has the advantage that other network systems are difficult to achieve, and is more powerful and stable in terms of network stability, network transmission and coverage. At present, the dependence of people on a communication network has risen to a new peak in history, and from eating, drinking and playing medical travel, the whole normal operation of society becomes more and more difficult without an internet of things card. The construction application of the intelligent street lamp of the urban road is the 4G internet of things communication technology, and the intelligent street lamp monitoring center can remotely control the on-off lamp of the street lamp in various strategies and modes through the 4G communication technology. The Internet of things card is used for networking transmission data to a platform or a server through the Internet of things card by arranging the Internet of things card in hardware equipment, and then can receive related instructions sent by the server and transmit the related instructions to the equipment for analysis and execution.
Communication system
In the street lamp control cabinet, the instruction transmission communication among the electric energy measurement terminal, the electric leakage monitoring terminal and the concentrator terminal and the intelligent street lamp illumination control terminal adopts an RS485 communication technology. When the RS485 interface is used, for a specific transmission line, the maximum cable length allowed from the RS485 interface to the load for data signal transmission is inversely proportional to the baud rate of the signal transmission, and the length data is mainly affected by factors such as signal distortion and noise. In theory, when the communication rate is 100Kbps or less, the longest transmission distance of RS485 can reach 1200 meters, but in practical application, the transmission distance is also different due to the transmission characteristics of the chip and the cable. In the transmission process, a method of adding relays can be adopted to amplify signals, and at most eight relays can be added, namely, the maximum transmission distance of RS485 can reach 10.8 km theoretically. In the aspect of urban road street lamp power supply, the electric energy loss of a street lamp cable line is often considered, and each street lamp cable which is changed from a street lamp special box is generally not more than 1.5 km. Therefore, the RS485 technology is applied to the street lamp electric energy measurement, the street lamp control function can be realized without adding a relay or laying an optical fiber, and the purpose of realizing intelligent street lamp measurement by utilizing the existing power supply cable is truly achieved.
Electrodeless dimming
The electrodeless dimming is in a lighting period, and the illumination intensity of the external environment and the illumination intensity requirement of the pedestrian vehicle in different periods are different. Intelligent street lamp system is provided with LED with electrodeless dimming function
The street lamp, the single lamp controller installed in the lamp or the lamp post can execute dimming according to a system preset control strategy, for example, the lamp is adjusted to 100% illumination when the demand is high, the lamp is adjusted to 80% illumination when the demand is high, and the lamp is adjusted to 50% illumination when the demand is low.
Power supply line leakage monitoring
The electric leakage monitoring terminal is arranged in the street lamp control cabinet, the detection range of the electric leakage monitoring terminal covers the whole circuit, the distance is not limited, and the monitoring input current (secondary side current of the transformer) is generally set to be in the range of 0-500 m A. The leakage monitoring terminal is used for monitoring the leakage state of the street lamp, provides alarm output during leakage, has the advantages of simple use, flexible and convenient installation, reliable operation, complete functions, friendly interface and the like, and is formed by adding the leakage monitoring terminal and background leakage monitoring software on the basis of installing the intelligent street lamp illumination control terminal.
When the street lamp power supply line has electric leakage, the electric leakage monitoring system timely and accurately sends information to the hands and the background of the operator on duty, and the site is automatically powered off, so that electric shock accidents are prevented; after the leakage fault is eliminated, the leakage protection outage and reclosing functions can be remotely eliminated.
