working principle
This device is composed of a light curtain for measuring vehicle length, an opposite-beam one-line positioning switch, a laser sensor scanner for measuring vehicle width and vehicle height, a high-speed signal processing module, and a computer.
The staff drove the vehicle vertically to the area of the measuring device at a speed of 3-7km/h, and the through-beam one-line infrared status switch of the length measuring part in the measuring device began to work. When the head of the vehicle travels to the last set of through-beam one-line positioning switches, the laser scanners installed on the left and right sides above the vehicle to measure the width and height of the vehicle start to work, and when the head of the vehicle under test enters the infrared light curtain that measures the length of the vehicle , the length dimension can be obtained. When the rear of the vehicle under test drives away from the last set of through-beam one-line positioning switches, the width and height dimensions of the vehicle under test are obtained. Finally, after high-speed signal processing and software synthesis, the three-dimensional graphics of the tested vehicle are displayed, and moving parts such as rear view mirrors can be removed by software.
main feature
High degree of automation: Automatically measure the length, width and height of the vehicle outline, and the measurement process does not require manual intervention.
Fast speed: software that integrates parallel algorithms and runs on high-performance industrial computers with multiple CPUs. Automatically measure the outline dimensions of cars (including the height of the cargo box panel) at low speeds (3-7km/h), and it takes about 5-25 seconds to detect a car.
High measurement accuracy: The measurement accuracy is ≤±20mm, which can meet the requirements of Article 3 (8) in the “Notice on Further Strengthening the Administration of Vehicle Announcements and Registration Relevant Matters” in the document of the State Economic and Trade Commission (Guo Shi Jing Industry [2002] No. 768). Paragraph 1: Requirements for the allowable range of dimensional tolerance of vehicle products ± 1%.
Visualization of the inspection process: The three-dimensional outline graphics and size data of the vehicle are dynamically displayed on the computer screen. Data processing can be performed according to the requirements of the national standard GB1589-2004 "Road Vehicle Outline Dimensions, Axle Loads and Quality Limits", and the influence of factors such as position indicator lamps and rearview mirrors can be easily filtered out.
The measurement results are stored in the database for easy access and review.
Strong practicability: The "no-stop" pass-through detection method is adopted, and the requirements for the driver's operation are low; the equipment installation does not occupy the site.
The measurement system has obvious advanced nature, high stability and reliability, good scalability and flexibility, convenient operation, convenient calibration and maintenance, and long effective service life.
The system software is WINDOWS operating system, using visual programming tools, SQL database, reasonable man-machine interface, powerful detection function, high detection efficiency, simple operation, easy maintenance, strong scalability, and high networking compatibility.
Network interface: The system software is linked with the vehicle detection network to facilitate control and data exchange. The system also has networking interfaces with management departments at all levels, which can be programmed according to the requirements of users and local management departments.
