CSD-8F series motor vehicle speeding on-site verification device

Series of motor vehicle speeding on-site verification devices
1. Overview
-Series of motor vehicle speeding on-site verification devices are independently developed by Zibo Chuangyu Electronics Co., Ltd. and are based on R high-performance 3-bit microcontrollers. The core intelligent testing instrument is used to test the vehicle's power performance and handling performance. The system uses a large-screen LCD display with Chinese character prompts to display multiple test data and curves in real time, which is clear and intuitive. The test items adopt menu-based operation, which is simple and easy to use. Sensor coefficients and test parameters are automatically stored by the system and will not be lost after power failure, and there is no need to re-enter. The whole machine design conforms to ergonomics and is easy to control. It is an ideal testing equipment for the automobile manufacturing industry, automobile maintenance industry, automobile testing, scientific research department and agricultural machinery testing department
Equipped with a standard R3 interface, the test results can be sent to Other computers can also be controlled by the system computer to complete the entire test project. Users can easily perform secondary analysis, processing or storage of the data using a system computer or laptop. (See the appendix for data format details)
This machine provides a level self-check signal of . (corresponding to a vehicle speed of .km/h), which facilitates calibration and maintenance of the instrument.
2. Main test items
Vehicle speed test: test distance, test time, average vehicle speed (minimum stable vehicle speed, maximum stable vehicle speed)
Slide test: initial taxi speed, taxi distance, taxi time
/> Braking test: initial braking speed, braking distance, braking time, maximum deceleration, average deceleration, (fully developed average deceleration)
Acceleration test: acceleration distance, acceleration time, final acceleration speed As well as the speed, distance and time at the beginning and end of the shift
