Problems solved by technology

[0004] Due to the single control strategy of the above methods, the operation is troublesome, and it is easy to frequently misoperate the street lamps in case of abnormal interference, the control error is large, and the environmental influences such as weather, season, time and geographical location cannot be considered, and it is impossible to achieve on-demand The purpose of turning on the lights does not guarantee traffic safety
[0005] At present, the dimming control methods in the night time period mainly include the following: (1) All-night lights: Most of the street lights in our country adopt the control mode of all-night lights (street lights are in a full-on state all night), which will cause electric energy unnecessary waste and reduce the service life of lamps
(2) Mid-night light: that is, in the second half of the night, the lighting control mode is adopted in 1 / 2 (the lamp is on every other) and 1 / 3 (the lamp is on every two) lighting control mode. Although this method saves power, it will lead to uneven illumination. It affects the comfort of driving, brings hidden dangers to traffic safety, and increases the difficulty and cost of construction

Embodiment 1

[0041] Embodiment one: see figure 1 , according to the present invention, a lighting system that relies on environmental data and fuzzy control of street lamps in different time periods. It includes single lamp controller, centralized controller and remote monitoring center. Data transmission in this system is based on two different wireless communication modes (short-distance ZigBee communication mode and long-distance GPRS communication mode). The ZigBee network realizes the communication between the single lamp controller of each street lamp and the centralized controller, and the GPRS network realizes the communication between the centralized controller and the remote monitoring center (22). When the remote monitoring center (22) needs to check the street lamp status information, the sensor module of the street lamp single lamp controller is responsible for collecting the street lamp status information in real time, and uploads the ZigBee networking module (15) to the cen...

Embodiment 2

[0042] Embodiment two: see figure 2 with image 3 , the main tasks completed by the single lamp controller are: join the ZigBee network, read / write street lamp data, send and receive and process the data and commands of the ZigBee network, and operate the street lamp according to the received command. The network communication module (12) of the single-lamp controller is responsible for the communication networking of the single-lamp node, and mainly handles interruptions correspondingly. There are two types of interrupts to be processed: one is ZigBee network interruption, and the other is serial port interruption. After the network communication module (12) starts and initializes, it needs to wait to join the network. After joining the network, it waits for an interrupt to be generated. After receiving the interrupt, it performs an interrupt processing program, and performs different operations according to different interrupts. The ZigBee network interrupt is used to rece...

Embodiment 3

[0043] Embodiment three: see Figure 4, the centralized controller collects the data of each single lamp controller in the jurisdiction area through the ZigBee networking module (15), and sends these data to the GPRS wireless communication module (19), so the centralized controller is equivalent to the lighting system. gateway. After the centralized controller receives the control command issued by the remote supervision center (22), the command is converted through the protocol, and sent to the ZigBee networking module (15) through the serial port, and the centralized controller receives the ZigBee networking module (15) at the same time. The data and the received data are encapsulated according to the protocol, sent to the public network server (20) through the GPRS wireless communication module (19), and record the time. In addition, the concentrator is designed with a button circuit (18), which can configure the system to change the control mode of the street lamp and upd...

Abstract

The invention discloses an environmental-data-based lighting system and method for fuzzy control of street lamps in different periods. The system comprises three components: single lamp controllers, a concentrated controller and a remote monitoring center. Combined with ZigBee short-range wireless network technology and GPRS remote wireless network technology, the system and method can achieve remote control on and information exchange among the street lights. In view of the fact that the control strategy for the street light control technology is too simple to meet the requirement of on-demand lighting under complicated and changing environmental factors, the invention provides an environmental-data-based lighting system and method for fuzzy control of street lamps in different periods. In the system and the method, the influencing factors regarding the environmental luminance at dawn and the dusk as well as the vehicles and pedestrians on street in the middle of the night are considered respectively, and through the fuzzy control methods adopted in different periods, it is possible to improve the control precision of the system so as to meet the dual requirement of both lighting quality and power conserving. According to the invention, it is not only possible to realize fuzzy control to the lighting of street lamps in different periods based on environmental data, but also possible to detect the power consumption of each street lamp, the tilting of a lamp post, and the road water in real time.

Description

technical field [0001] The invention relates to the field of intelligent control technology of street lamp lighting, in particular to a lighting system and method for fuzzy control of street lamps in time periods based on environmental data. Background technique [0002] With the increasing number of street lamps on the road, the municipal government continues to improve the road lighting system in order to maximize the saving of electric energy. There are two main parts in the application of energy-saving control technology to the lighting system of urban street lamps, one is the switch light control at dusk and dawn, and the other is the dimming control during dark hours. [0003] At present, the switch light control methods in dusk and dawn hours mainly contain the following: (1) manual control: mainly turn on and off street lights with manual operation. (2) Timing control: mainly based on time as the switch light, completed by the timer control, can switch the light at ...
