Description

Technical Field

[0001] The utility model relates to the technical field of street lamp control, and more particularly to a compact street lamp lighting controller. Background Art

[0002] In modern urban lighting systems, street lighting controllers play a vital role, responsible for monitoring and managing the operating status of street lights. However, traditional street lighting controllers have some significant flaws in their design and practical application, which seriously affect their performance, cost and market promotion.

[0003] First, the manufacturing cost of traditional controllers is high, mainly due to their complex circuit design, cumbersome production process and expensive material selection. The high cost not only increases the purchasing pressure of consumers, but also limits the application of products in a wider range of fields.

[0004] Secondly, the bulk of traditional street lighting controllers not only brings many inconveniences during the installation process, especially in space-constrained environments, but also increases transportation and warehousing costs. The inconvenience of large equipment in the logistics process further affects the market competitiveness of the product.

[0005] Furthermore, the external communication antenna in the traditional design seriously affects the waterproof performance of the controller. The external antenna destroys the overall sealing of the device, making the controller susceptible to erosion by moisture and dust in harsh outdoor environments, thereby reducing its service life and stability.

[0006] Finally, traditional controllers are relatively difficult to maintain due to their complex structure. Once a failure occurs, the process of repairing and replacing parts is often time-consuming and labor-intensive, increasing maintenance costs and difficulty.

[0007] In summary, traditional street lighting controllers have problems that need to be improved in terms of cost, size, waterproof performance and maintenance. Utility Model Content

[0075] Working principle:

[0076] The utility model is mainly reflected in the interaction and data flow between its internal modules. First, the external antenna on the side of the shell receives external wireless signals. These signals are transmitted to the CAT1 communication module via the SMA antenna base. The communication module is responsible for processing these signals and exchanging data with the power chip module through the universal asynchronous receiver and transmitter interface;

[0077] The power chip module serves as the energy management center of the entire controller, responsible for monitoring and managing the distribution and use of electrical energy. It connects to the first power module (DC-voltage conversion module) to ensure a stable DC power supply to all components within the main control module. It also uses the current acquisition module to obtain real-time current information in the circuit for precise energy management.

[0078] The voltage stabilization module is located below the main control module. It ensures voltage stability for the entire system through the voltage stabilization substrate and the modules on it. The second power supply module (AC-voltage conversion module) converts external AC power into the DC power required by the voltage stabilization module. At the same time, the voltage acquisition circuit module monitors voltage changes in real time. When the voltage fluctuates, the conversion circuit module (pulse width modulation conversion circuit module) adjusts its output to maintain voltage stability. The relay controls the on / off state of the street light according to the control signal.

[0079] The connection between the modules is mainly achieved through board connectors. The first board connector is responsible for data exchange within the main control module and between it and the voltage regulator module, while the second board connector is responsible for the connection within the voltage regulator module and with the external power supply. These connectors not only simplify the circuit design, but also improve the reliability and maintainability of the system.

[0080] The principles of compact street lighting controller are mainly reflected in the following aspects:

[0081] Modular design:

[0082] The controller consists of two core parts: the main control module and the voltage stabilizing module. Each module has its own specific functions and roles. This design makes the entire system more concise and efficient.

[0083] The main control module is responsible for processing data, controlling the switching and brightness adjustment of street lights, while the voltage stabilization module ensures stable power output. The two work together to maintain the normal operation of the system.

[0084] Power Management:

[0085] The voltage stabilization module ensures system voltage stability by stabilizing the substrate and the various circuit modules on it, preventing damage to equipment caused by voltage fluctuations. This design greatly enhances the stability and reliability of the controller.

[0086] Intelligent Control:

[0087] The collaborative work of the power chip module and the current acquisition module enables refined management of electrical energy. By monitoring current and voltage in real time, the controller can precisely control the on / off status and brightness of streetlights, thereby improving energy efficiency.

[0088] The CAT1 communication module and SMA antenna base give the controller powerful wireless communication capabilities, allowing it to remotely receive instructions and adjust the status of street lights in real time, realizing intelligent management.

[0089] Cost-effectiveness:

[0090] By deeply optimizing the circuit scheme and device structure, the controller successfully reduced costs by more than 40% while maintaining the integrity of product functions, which greatly improved the product's market competitiveness.

[0091] In summary, the principles of compact street lighting controllers are mainly reflected in modular design, power management, intelligent control, and cost-effectiveness. These principles together ensure the stability, intelligence, and economic benefits of the controller.
