In AIoT applications, sensors are one of the core components, which are responsible for sensing the external environment. We are committed to the development, production and sales of laser sensors based on VCSEL, providing a variety of laser sensor products and overall solutions for AIoT applications. Xinliang intelligent laser sensors include proximity sensors, laser ranging sensors and lidar; covering applications from smart homes, industrial control, intelligent driving and security.
Traffic flow monitoring
The traffic flow and event monitoring system is one of the important components of a new generation of urban road and highway intelligent transportation. There are currently three commonly used solutions on the market: 1) coil-based technology detection system: low investment, but extremely high construction and maintenance costs; 2) microwave technology-based monitoring system: less affected by weather, but poor resistance to electromagnetic interference; 3) based on Video monitoring system: easy to install and greatly affected by weather.
As the core sensor supplier of VCSEL, Xinliang Intelligent has extremely strong solution capability. Its medium and long-range laser ranging sensors make up for the shortcomings of the video detection system. By combining the traffic software analysis system to complete the monitoring of traffic flow and velocity, vehicles and road abnormal events.
Principle of the scheme: This scheme consists of two single-point laser ranging sensors (the specific model depends on the use environment), the control board and the basic installation structure. Two laser ranging sensors are installed at an angle of 40 °, one measuring vertically and the other downward. The main control board collects the data of the two sensors and calculates and outputs the vehicle type recognition result through the internal algorithm. The result can be displayed on the external LED screen or directly transmitted to the customer's main system.
Solution advantages: high recognition accuracy, fast response speed, multi-scene application, high frame rate and high performance, high system integration, easy installation, and support for expanded function development.
The 50-200m distance measuring sensor A4 is the key device of this solution, which is used for vehicle model identification, vehicle flow statistics, captain speed detection, ETC trigger, vehicle over-height detection, monitoring of vehicles entering and exiting highway gates, parking lot entrances, etc.
The 50-200m laser distance sensor A4 is a cost-effective distance sensor. It has a number of technical patents and is specifically designed for high-speed moving targets, such as helicopters, cars, and trains.
advantage:
u Use VCSEL light source, high reliability;
u High precision and long distance;
u Measurement frequency up to 200 / 1000Hz;
u Real-time performance is good; waterproof and dustproof IP67;
u Wide operating temperature range -30-60 ° C;
u Small size: 55x60x35mm.
