Description

Technical Field

[0001] The present invention belongs to the technical field of street lamps, and in particular relates to a street lamp with air environment monitoring function. Background Art

[0002] Streetlights are an important part of infrastructure. With the development of society, street lighting has gradually become large-scale, but the existing streetlights are still relatively simple in function and only serve as lighting at night. At present, air monitoring equipment is unevenly distributed and costly. Independent air monitoring stations are usually limited in distribution, making it difficult to fully cover all areas of the city. In addition, it is costly to set up monitoring equipment separately, especially in remote areas. Due to the lack of monitoring stations, it may be impossible to accurately understand the local air quality conditions. Based on the current situation, a streetlight with air environment monitoring is proposed. The air environment monitoring equipment is integrated into the streetlight, which can use the existing distributed streetlights to monitor the air environment, saving resources and costs. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 It is a structural block diagram of the present invention. DETAILED DESCRIPTION

[0024] In order to better understand the purpose, structure and function of the present invention, the present invention is clearly and completely described below in conjunction with the accompanying drawings.

[0025] like Figure 1 The street lamp with air environment monitoring shown is characterized in that it includes: a lamp pole, a lighting device and an air monitoring device installed on the lamp pole, and a control system. The lighting device is used for lighting at night. In this embodiment, the lighting device is an LED lamp installed on the upper part of the lamp pole; the air monitoring device is used to monitor the environmental quality around the street lamp in real time, and provide timely and accurate air quality information to relevant departments and the public. The present invention integrates the air monitoring device on the street lamp, which greatly improves the comprehensive service capacity of the street lamp facilities. Compared with the traditional independent monitoring equipment, this integrated design does not require the construction of a separate monitoring site, reduces the cost and installation and maintenance workload, saves land resources and construction costs, and improves the utilization efficiency of the equipment; at the same time, due to the wide distribution of street lamps, air environment monitoring of every corner of the city is realized, which makes up for the defect of uneven distribution of traditional monitoring sites and forms a more comprehensive and sophisticated air quality monitoring network; it provides important data support for the intelligent management of the city, helps to achieve accurate governance and optimization of the urban environment, and improves the overall quality of the city and the quality of life of residents.

[0026] The control system includes a controller and an air monitoring module, a data processing module and a communication module electrically connected to the controller.

[0027] The controller is connected to the lighting device, that is, the controller is connected to the LED lamp to control the on and off of the LED lamp. In this embodiment, the lamp pole is also provided with a photosensitive sensor connected to the controller, and the photosensitive sensor is used to collect the brightness of the light near the street lamp and convert it into an electrical signal, and transmit the converted electrical signal to the controller. The controller sends instructions to the LED lamp according to the brightness of the light detected by the photosensitive sensor, adjusts the brightness of the LED lamp, achieves the purpose of energy saving and comfortable lighting, and realizes a good road lighting effect.

[0028] The air monitoring module is connected to the air monitoring device and is used to transmit the air signal monitored by the air monitoring device to the controller. In this embodiment, the air monitoring device is an infrared transmitter and an infrared receiver arranged on the lamp pole. Since infrared transmitters and infrared receivers are arranged on all lamp poles, the air quality between two corresponding lamp poles can be monitored by corresponding infrared transmitters and infrared receivers. This air monitoring device mainly uses non-dispersive infrared absorption method (NDIR) to detect sulfur dioxide and nitrogen oxides; during the detection process, the infrared transmitter emits continuous broad-spectrum infrared light, which passes through the gas to be tested, wherein infrared light of a specific wavelength will be absorbed by sulfur dioxide or nitrogen oxide molecules, and the unabsorbed infrared light reaches the infrared detector; the infrared detector measures the intensity of the received infrared light, and by comparing the intensity difference between the incident light and the outgoing light, the absorption degree of the gas to the infrared light of a specific wavelength can be calculated; the calculation is based on the Lambert-Beer law. This method has the advantages of high accuracy and fast response speed, and is suitable for real-time monitoring of sulfur dioxide and nitrogen oxides. Of course, the air monitoring device may also be an air monitor installed on a lamp pole to monitor air temperature, air humidity, PM2.5, air visibility, and wind volume. This is a prior art and will not be described in detail here.

[0029] The data processing module is used to process the air signal received by the controller to generate an image signal; the communication module is used to connect to an external terminal and transmit the signal in the control system to the external terminal. Furthermore, the control system also includes a warning module connected to the controller, and the warning module is connected to a warning device; the warning module is used to instruct the controller to give a prompt to the warning device when the air signal value in the controller exceeds a threshold value. The warning device can be set as a buzzer and installed on an external terminal; when the buzzer sounds an alarm, the relevant department can take measures to improve the environmental quality, such as strengthening the emission supervision of enterprises in the area, or initiating emergency emission reduction measures.

[0030] In this embodiment, the communication module is connected to the external terminal through wireless technology; the wireless technology is 5G, WiFi, Bluetooth or LoRa. Among them, for the central area of ​​the city, WiFi transmission can be used; for some application scenarios with extremely high requirements for data real-time, 5G technology transmission can be used to ensure that the data is delivered to the relevant departments in a timely manner; for short-range ranges, such as data interaction with nearby mobile monitoring equipment or maintenance personnel's handheld terminals, Bluetooth transmission can be used; for scenarios with a wide coverage range and low power consumption requirements, LoRa transmission can be used. For example: in a large industrial park, some areas have good 5G signals, and street lights use 5G to transmit data; while in places with weak signals at the edge of the park, it switches to LoRa transmission; on city streets, if there are public WiFi hotspots nearby, street lights give priority to WiFi transmission to save communication costs.

[0031] Of course, the control system also includes a power module, which is connected to a power source and is used to provide power to the control system. The power source can use the power supply facilities of the existing street lamp itself to reduce operating costs. A display screen electrically connected to the controller is also provided on the lamp pole, and the public can obtain air quality information within this range from the display screen.

[0032] In the present invention, the lamp pole is made of high-strength, corrosion-resistant materials to ensure that the street lamp can operate stably outdoors for a long time and withstand various adverse weather conditions. The control system can be integrated into a microprocessor installed in the lamp pole to process and analyze the collected data in real time, remove abnormal values ​​and interference, and ensure the accuracy and reliability of the data; the microprocessors on multiple street lamps within a range are transmitted to the superior control center through the communication module, and multiple system centers are then uniformly uploaded to the general control center, and the transmission is from bottom to top, which is convenient for the relevant departments to centrally manage and plan.

[0033] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
