Method for controlling networking of regional street lamps

Abstract

The invention provides a method for controlling networking of regional street lamps, and the method can be used for solving the technical problem of interrupted street lamp control signal caused by communication failure. The technical scheme adopted by the invention is as follows: the method is based on a power line carrier technology, and urban street lamps are strobed by output power lines of acontrol transformer of a master controller at a station end. The method is characterized by comprising the following steps: defining transverse sections and vertical sections to form an area crossed grid structure formed by four sections; setting at least one subcontroller of the control transformer in each grid structure; and setting a transverse street transformer or vertical street transformeron the joint of the defined transverse and vertical sections respectively. The method has the advantages that by utilizing a regional grid type layout, when the communication on a certain position ofthe transformer is failed, the communication can be switched over by virtue of a wireless communication module in other regions, so that the communication smoothness is ensured.

Description

technical field [0001] The invention relates to the construction of an urbanized lighting system, specifically a management and control method for street lamps in a cross grid area formed on the basis of four horizontal and vertical road sections. Background technique [0002] Street lamp control technology is a control technology that has developed rapidly in recent years. Many cities have used monitoring control and data acquisition systems to monitor urban street lamps. At present, there are mainly the following control methods used in street lighting: loop control method, and street lamp single lamp control system based on microcomputer control. [0003] 1. Loop control method. It is to control the street light circuit with A, B, and C separately, and use a single-chip microcomputer or PLC controller to control different circuits to achieve energy-saving effects. The advantage of this control method is that the cost of the controller is low and the control is simple. ...

AI Technical Summary

Problems solved by technology

[0005] For the communication method using power carrier technology, the centralized controller generally manages the range of street lamps to which a transformer belongs, and cannot be controlled across the transformer. A transformer must be installed with a centralized controller. Therefore, for large-scale control, the amount of centralized control is large, and the management is complicated. Hardware cost and installation cost are too high

[0006] For ZIGBEE short-range wireless communication, the wireless communication method is relatively subject to external interference, so generally the range of a centralized controller is relatively small, generally no more than 200 lights, and for large-scale control, the centralized control requires a large amount of management and complex management. Hardware cost and installation cost are too high

[0007] The above two methods are basically divided according to road sections, so the requirements for the concentration of the street lamp area are high, and there are too many nodes installed. The long-distance wireless communication method is generally used between the centralized controller and the microcomputer management center, so it is limited by the long-distance wireless communication method. The interference is large, and it is difficult to achieve a seamless link. When it is severely interfered or a partial power failure occurs, it may cause a large area of ​​communication failure, and it is difficult to achieve a good management effect

Due to the use of GPRS transmission in the prior art, once a section of the road is shielded or blocked by the signal, the communication of the control signal will cause failure, which will inevitably affect the lighting of the road in this section.
