In the modern logistics system, warehouse is not only the center of commodity storage, but also the key link of efficiency and cost control. Efficient warehouse management is inseparable from scientific and reasonable lighting scheme, which is directly related to the work efficiency, operation safety and energy consumption of employees. With the rapid development of the Internet of Things technology, 24G millimeter wave radar human micromotion sensor, as an innovative technology, is gradually becoming an important promoter of the intelligent upgrade of warehouse lighting. This paper will deeply discuss the application of this technology in the warehouse lighting scheme, analyze its advantages, working principle, implementation strategy and future development trend, aiming at providing a set of efficient, energy-saving and intelligent lighting solutions for warehouse managers.

Introduction: The challenges facing warehouse lighting

Traditional warehouse lighting mostly uses a fixed lighting mode, that is, regardless of whether someone is active in the warehouse, the light remains constant brightness. This method not only wastes a lot of power, but also may cause light pollution when there is no personnel working, affecting the visual comfort of night operators. In addition, long-term exposure to strong light may also adversely affect the storage environment of goods in the warehouse. Therefore, looking for an intelligent lighting system that can automatically adjust brightness according to personnel activities has become an urgent problem to be solved in warehouse management.

Second, the technical advantages of 24G millimeter wave radar human micromotion sensor

2.1 High-precision detection

24G millimeter wave radar human micromotion sensor uses millimeter wave frequency band for non-contact detection, and can accurately identify human micromovements in the warehouse, such as walking, bending, raising hands and other subtle movements. Compared with infrared sensor, which is susceptible to the interference of environmental factors such as temperature and humidity, millimeter wave radar has stronger anti-interference ability and higher detection accuracy.

2.2 Long-distance Coverage

Thanks to the characteristics of millimeter wave, 24G millimeter wave radar sensor can achieve a long detection distance and cover a large area, which is suitable for empty and tall space environment in warehouses. This means that even in large warehouses, effective monitoring and lighting control of the whole area can be achieved.

2.3 Low power design

Using advanced low-power technology, 24G mmwave radar sensors can maintain low energy consumption during standby and detection, helping to reduce the operating cost of the entire lighting system. At the same time, its high sensitivity allows the sensor to respond to human activity in a short time, avoiding unnecessary energy consumption.

2.4 Intelligent Linkage

By integrating into the intelligent lighting system, the 24G millimeter wave radar human micromotion sensor can achieve seamless docking with other intelligent devices (such as LED lamps, controllers, etc.), and automatically adjust the light brightness, switch status, etc., according to personnel activities, to achieve intelligent management of warehouse lighting.

Third, intelligent lighting scheme design based on 24G millimeter wave radar

3.1 System Architecture

The intelligent lighting system is mainly composed of 24G millimeter wave radar human micromotion sensor, intelligent luminaries, controller and cloud platform. The sensor is responsible for real-time monitoring of personnel activities in the warehouse, and the data is transmitted wirelessly to the controller; According to the received data, the controller can accurately control the intelligent lamps and realize the intelligent adjustment of the lights. The cloud platform is responsible for remote monitoring, data analysis and policy optimization, providing warehouse managers with a comprehensive and intuitive lighting management interface.

3.2 Working Principle

When there are personnel activities in the warehouse, the 24G millimeter wave radar human micromotion sensor immediately captures the human micromotion signal and converts the signal into an electrical signal to send to the controller. According to the preset algorithm, the controller analyzes the location, frequency and intensity of the person's activity, and then adjusts the brightness of the light in the corresponding area. For example, in areas where people are frequently active, the brightness of the light automatically increases to a higher level; In unmanned areas or areas with less human activity, the light automatically reduces the brightness or turns off to achieve the purpose of energy saving.

3.3 Scenario Application

Warehousing and warehousing areas: In the high-frequency activity areas such as cargo loading and unloading, warehousing and warehousing, the intelligent lighting system can automatically adjust the brightness of the light according to the movement of personnel and goods, ensuring that the working area is fully lit and improving work efficiency.

Aisle between shelves: The use of sensors to monitor the flow of people in the aisle between shelves, and dynamically adjust the brightness of the lights on both sides of the channel, both to ensure the safety of the operation and avoid unnecessary energy waste.

Warehouse office area: According to the rest time and working status of the office staff, intelligent adjustment of the lighting brightness of the office area to create a comfortable office environment.

Emergency lighting: In an emergency, the intelligent lighting system can quickly switch to the emergency lighting mode to ensure the smooth progress of personnel evacuation and rescue work.
