Part One: Introduction of human body sensing technology

1.1 Background of human body sensing technology

Human body sensing technology is a kind of technology that realizes automatic monitoring by sensing human body infrared radiation signal. The basic principle is to use the infrared radiation sensor to sense the heat radiation of the human body, so as to judge the existence of the human body and realize the automatic control of the corresponding equipment.

1.2 Application of traditional human body sensor switch

The traditional human body induction switch usually adopts infrared induction and ultrasonic induction technology. However, there are some shortcomings in the use of these technologies, such as short sensing distance and sensitivity to ambient light, which limit their application in the field of stair lighting.

2.1 Principle of radar body sensor

Radar body sensor uses the principle of radar reflection of objects. Its working process is similar to the radar system, by transmitting continuous weak radar signals, and receiving and analyzing the signal reflected back by the target object to judge the position and dynamic information of the target object.

2.2 Characteristics of radar body sensor

(1) Long sensing distance: radar body sensors can achieve long-distance monitoring, which is more advantageous than traditional infrared sensing technology.

(2) Not affected by ambient light: the radar human body sensor is not affected by ambient light, and can achieve accurate human body sensing.

(3) Strong anti-interference ability: the radar human body sensor can still accurately sense the human body in a complex environment, and has a high anti-interference ability.

Part three: Application of radar human body sensor in stair lighting

3.1 Function of radar body sensor

Radar body sensor plays a key role in stair lighting and can realize intelligent stair lighting control. By sensing the presence of the human body or not, timely adjust the lighting brightness of the stairs to provide a good lighting effect, but also to achieve efficient use of energy.

3.2 Advantages of stair lighting system

(1) Energy saving and environmental protection: the stair lighting system is controlled by intelligent induction without manual operation, which can effectively reduce energy waste and improve energy utilization efficiency.

(2) Safe and reliable: the stair lighting system can intelligently adjust the lighting brightness according to human activities, and provide sufficient lighting in time to improve the safety of pedestrians in the stairwell.

(3) Comfortable experience: the stair lighting system can intelligently adjust the lighting brightness according to the position of the human body to provide users with a comfortable lighting environment. Whether it is day or night, the user will feel the appropriate lighting when walking on the stairs, avoiding uncomfortable problems such as glare or lack of light.

3.3 Application examples of radar human body sensor in stair lighting

(1) Automatic sensor switch: the radar body sensor can be connected with the lighting equipment, and when the user is sensed to approach the stairs, the lighting equipment will be automatically turned on. When the user leaves after a certain time, the lighting equipment automatically shut down, to achieve the function of automatic induction switch.

(2) Intelligent dimming control: the radar body sensor can intelligently adjust the lighting brightness according to the user's position and activity. For example, when the user approaches the stairs, the lighting system will automatically increase the brightness to provide adequate lighting, and when the user leaves, the lighting system will gradually reduce the brightness, achieving energy savings and comfort for human activities.

(3) Application of energy saving strategies: the radar body sensor can be connected with the intelligent control center of the stair lighting system to formulate energy saving strategies according to the user's activities. For example, increase the brightness of the lighting during the period of intensive personnel and reduce the brightness during the period of sparse personnel, so as to achieve the purpose of saving energy.

4.1 Working principle of radar body sensor

The radar body sensor determines the position and dynamic information of the object by sending a continuous weak radar signal and receiving and analyzing the signal reflected back by the object. When a human body is near the position installed by the radar body sensor, the sensor will receive the radar signal reflected back by the human body, so as to determine the presence of the human body. The sensor transmits this information to the control center of the stair lighting system, and performs corresponding lighting regulation according to the set strategy.

4.2 Working principle of stair human sensor switch

Stair body sensing switch is a device designed based on the working principle of radar body sensor. It usually includes radar sensor, control chip, relay and other components. When someone approaches the staircase where the switch is located, radar sensors sense the presence of the human body and send a signal to the control chip. The control chip determines whether the lighting device needs to be turned on or off, and uses the relay control signal to achieve the corresponding operation.

Radar human sensor Stairway human sensor switch principle plays an important role in stair lighting. It realizes long distance and accurate human body sensing through the principle of radar reflection, has the advantages of strong anti-interference ability and is not affected by ambient light. The application in the stair lighting system makes the lighting have the functions of intelligence, energy saving, environmental protection, safety and reliability, and provides users with a comfortable lighting experience.

In the future, with the continuous progress of science and technology, the application of radar human sensor stairway human sensor switch will continue to expand and improve. For example, it can be combined with smart home systems to achieve linkage with other devices, such as smart audio, smart door locks and other devices, to achieve a more convenient user experience and comprehensive intelligent control.

In addition, with the development of artificial intelligence technology, the radar human sensor staircase human sensor switch can also autonomously perform intelligent lighting adjustment by learning and analyzing the user's behavior habits. For example, according to the user's time habits and space needs, the system can automatically adjust the brightness and color of the lighting, providing more personalized and accurate lighting services.
