According to requirements in GB21861-2014Items and methods of motor vehicles safety technology inspectionissued by Ministry of Public Security, heavy and medium trucks, special motor vehicles and trailers shall be measured with outside dimensions automatic measuring device which shall comply with metrological regulations with a maximum permissible error of ± 1% or ± 20mm.
The traditional means of detection is still in the stage of manual measurement. There tend to be great errors in the data and measurement cannot be monitored.
This product can detect the length, width and height, axle number and spacing of the vehicle through raster more accurately than the traditional manual detection and has passed certification of Anhui Institute of Metrology. The product is absolutely superior to the existing video detection and radar detection which are greatly influenced by natural environment, difficult to implement and cost more.
The product consists of the core control unit, information acquisition unit (gantry, grating), video monitoring unit (optional), voice broadcast unit (optional) and LED display unit (optional).
Function and Performance
The vehicle external contourgraph is mainly used to automatically detect the feature size of the vehicle’s external contour. Integrating optical, electronic, computer and other high technologies in one, the product can realize automatic, visualized and networked detection process and online access to data of the vehicle’s external contour to greatly improve the detection efficiency.
Non-contact online measurement: The vehicle does not need to stop during the measurement process
Wide measurement range: Special measuring light curtain of a high collection speed is developed to detect a variety of models
High measurement accuracy: Measuring error of no more than 1%/20mm
High degree of automation: Automatic detection process without human intervention
High measurement speed: Parallel detection of the vehicle’s length, width and height
High scalability: The system design adopts modular thinking to facilitate the subsequent function extension
Convenient communication: Integrate with other information systems of the user to acquire or send data
High reliability: The product uses sophisticated technology and simplified and modular design thinking to achieve a high reliability
Easy maintenance: In case of failure, the user may inspect the product to quickly identify and easily disassemble and replace the failed part
Safety: The product has adopted comprehensive safety design and will not pose a safety risk to vehicles and personnel during the process of use.
1. A 10 meters wide and 5 meters long horizontal platform is required to be provided on the assembling floor. The height error should not exceed 1% and a roof is preferred to prolong its service life.
2. The gantry should be customized according to the requirements of Keli and installed in the slot on the ground, and a crane is required during the installation process.
3.Eight pairs of raster modules are required, three to measure the length, two to measure the width and three to measure the height, installation should be performed by professional and technical personnel due to requirements for high accuracy.
4.The back-stage module can be flexibly deployed on WINDOWS of a general computer.
Advantages of the Product
1.The product adopts raster detection to get rid of disadvantage of the existing video detection of being greatly influenced by natural environment.
2. The product is easy to implement so as to get rid of disadvantage of the existing video detection of long time and great difficulty to implement.
3. The product is cost-effective and the entire device is about 200,000 yuan, so as to get rid of the disadvantage of the existing radar detection of high cost.
