[0002] At present, the annual power consumption of urban public lighting accounts for about 4% to 5% of my country's total power generation, and accounts for 30% of my country's lighting power consumption, which is equivalent to the annual power generation of the Three Gorges Hydropower Project (85 billion kwh). , but street lighting is mostly low-efficiency lighting, lack of energy-saving management, power utilization is less than 65%, power waste...

Abstract

The invention discloses a LoRa technology-based intelligent streetlamp management system, and relates to the fields of a wireless communication technology and a sensor technology. The intelligent streetlamp management system comprises streetlamp sensing nodes, a data processing terminal, an information center and a repair reporting client end, wherein each streetlamp sensing node is in bidirectional wireless communication with the data processing terminal through a LoRa communication mechanism; each streetlamp sensing node transmits streetlamp state information, ambient light strength information and PM2.5 monitoring data to the data processing terminal; the data processing terminal performs real-time processing on the data from each streetlamp sensing node, controls on-off and luminance of a corresponding streetlamp, and transfers the received information and data to the information center; the information center performs analysis, statistics and storage on the information and data from the data processing terminal; and the repair reporting client end can provide a suggestible maintenance scheme. By virtue of the intelligent streetlamp management system, electric energy utilization rate of the streetlamp or a landscape lamp can be improved, and energy efficiency management and energy saving can be realized; and the intelligent streetlamp management system has the advantages of multi-stage concentrated management, flexible monitoring modes and high expandability.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] refer to figure 1 , The intelligent street lamp management system based on LoRa technology of the present invention includes n street lamp sensing nodes U11-U1n, data processing terminal U2, information center U3 and repair client U4.

[0029] The street lamp sensing nodes U11 to U1n perform two-way wireless communication with the data processing terminal U2 through the LoRa communication mechanism. The street lamp sensing nodes U11 to U1n send street lamp status information, ambient light intensity information and PM2.5 monitoring data to the data processing terminal U2.

[0030] The data processing terminal U2 performs real-time processing on the information and data from the street lamp sensing nodes U11-U1n, and issues control commands to the street lamp sensing nodes U11-U1n to control the on-off and brightness status of the street lamps. At the same time, the data processing terminal U2 forwards the received information and data to the information center U3.

[0031] The information center U3 analyzes, counts and stores the information and data from the data processing terminal U2, and at the same time can send a control signal to the street lamp sensing nodes U11-U1n through the data processing terminal U2, and judge whether the street lamp needs to be according to the status information of the street lamp. For maintenance, the location information of the street lamps that need to be maintained is transmitted to the repair report client U4.

[0032] The repair reporting client U4 receives the street lamp status and location information from the information center U3, provides a suggested repair plan, and supports arranging supporting maintenance personnel to go for inspection and maintenance. The repair reporting client U4 is represented as a mobile device APP or computer application software.

[0033] refer to figure 2 Take the street lamp sensing node U11 of the intelligent street lamp management system based on LoRa technology of the present invention as an example, which includes a solar power supply module U111, a light sensor U112, a PM2.5 sensor U113, an MCU module U114, a street lamp control unit U115 and a first LoRa Communication module U116.

[0034] The solar power supply module U111 is used to supply power to the light sensor U112, the PM2.5 sensor U113, the MCU module U114, the street lamp control unit U115 and the first LoRa communication module U116. The solar power supply module U111 can be equipped with a super capacitor or a rechargeable battery, and realizes the power supply of the nighttime light sensor U112, PM2.

[0035] The light sensor U112 is used to sense ambient light intensity and transmit the ambient light intensity value to the MCU module U114.

[0036] The PM2.5 sensor U113 is used to sense the PM2.5 concentration value and transmit the PM2.5 concentration value to the MCU module U114.

[0037] The MCU module U114 is used to receive the ambient light intensity value and the PM2.5 concentration value from the light sensor U112 and the PM2.5 sensor U113; The street lamp control strategy is sent to the street lamp control unit U115; the MCU module U114 sends the ambient light intensity value and the PM2.5 concentration value to the first LoRa communication module U116, and simultaneously receives it through the first LoRa communication module U116 Control commands from data processing terminal U2.

[0038] The street lamp control unit U115 completes the control of the corresponding street lamp switch and brightness according to the control command issued by the MCU module U114.

[0039] The first LoRa communication module U116 completes the transparent transmission of data and commands between the data processing terminal U2 and the MCU module U114.

[0040] refer to image 3, the data processing terminal U2 of the intelligent street lamp management system based on LoRa technology of the present invention includes a first LoRa communication module U21, an ARM processing module U22 and an extended communication module U23.

[0041] The second LoRa communication module U21 completes the transparent transmission of data and commands between the first LoRa communication module U116 and the ARM module U22.

[0042] The ARM processing module U22 formulates a second street lamp control strategy according to the overall law of the ambient light intensity values around each street lamp managed by the data processing terminal U2, and sends control to the street lamp sensing nodes U11-U1n through the second LoRa communication module U21 Order. The ARM processing module U22 is connected with the extended communication module U23 through RS485.

[0043] The extended communication module U23 can be expressed as a GPRS module, a WI-FI module or a 4G module, and transmits location information such as ambient light intensity value, PM2.5 concentration value and road to the information center U3, and receives the information center U3 according to the patent implementation. According to the specific needs of personnel, the corresponding control commands of the third street light control strategy are formulated.

[0044] The priority of the street light control strategy is: the third street light control strategy > the second street light control strategy > the first street light control strategy.
